We're also +trying to make cairo better, and learning about the bugs that users +encounter is an essential part of that. So we really appreciate the +extra effort users put in to providing high-quality bug reports. + +There are two acceptable ways to report cairo bugs, and you can choose +which you prefer: + +1) Bugzilla bug tracking database: + + You can use the following web interface to report new bugs, follow + up on previous bug reports, and search for existing, known + bugs. Just use the "cairo" product: + + http://bugs.freedesktop.org + + It is necessary to go through a quick account creation process, + (with email address verification), in order to be able to report + new bugs in bugzilla. We apologize for any inconvenience that might + cause, and hope it won't prevent you from reporting bugs. + +2) Cairo mailing list: + + For people who cannot stand the bugzilla interface, you can just + send an email to cairo mailing list (cairo@cairographics.org). The + mailing list only allows posting from subscribers, so use the + following page for subscription instructions: + + http://cairographics.org/lists + + Again, we apologize for any inconvenience this subscription step + might cause, but we've found it necessary to require this in order + to enjoy spam-free discussions on the list. + + If you don't actually _want_ to be a subscriber to the mailing + list, but just want to be able to send a message, the easiest thing + to do is to go through the subscription process, and then use the + preferences page to disable message delivery to your address. + +Which of the above you use to report bugs depends on your own +preferences. Some people find just typing an email message much easier +than using the web-based forms on bugzilla. Others greatly prefer the +ability to check back on a specific bug entry in bugzilla without +having to ask on the mailing list if an issue has been resolved. + +Regardless of which method you use, here are some general tips that +will help you improve the quality of your bug report, (which will help +in getting the bug fixed sooner): + +1) Check to see if the bug has been reported already. It's pretty easy + to run a search or two against the cairo product in the + http://bugs.freedesktop.org bugzilla database. Another place to + look for known bugs is the cairo ROADMAP: + + http://cairographics.org/ROADMAP + + which shows a planned schedule of releases and which bug fixes are + being planned for each release. + +2) Provide an accurate description of the bug with detailed steps for + how we can reproduce the problem. + +3) If possible provide a minimal test case demonstrating the bug. A + great test case would be a minimal self-contained function in C or + python or whatever language you are using for cairo. The function + might accept nothing more than a cairo context, (cairo_t* in C). + +4) If you feel like being particularly helpful, you could craft this + minimal test case in the form necessary for cairo's test + suite. This isn't much more work than writing a minimal + function. Just look at the cairo/test/README file and imitate the + style of existing test cases. + + If you do submit a test case, be sure to include Copyright + information, (with the standard MIT licensing blurb if you want us + to include your test in the test case). Also, including a reference + image showing the expected result will be extremely useful. + +5) Finally, the best bug report also comes attached with a patch to + cairo to fix the bug. So send this too if you have it! Otherwise, + don't worry about it and we'll try to fix cairo when we can. + +Thanks, and have fun with cairo! + +-Carl diff --git a/CODING_STYLE b/CODING_STYLE new file mode 100644 index 000000000..95ceac04d --- /dev/null +++ b/CODING_STYLE @@ -0,0 +1,291 @@ +Cairo coding style. + +This document is intended to be a short description of the preferred +coding style for the cairo source code. Good style requires good +taste, which means this can't all be reduced to automated rules, and +there are exceptions. + +We want the code to be easy to understand and maintain, and consistent +style plays an important part in that, even if some of the specific +details seem trivial. If nothing else, this document gives a place to +put consistent answers for issues that would otherwise be arbitrary. + +Most of the guidelines here are demonstrated by examples, (which means +this document is quicker to read than it might appear given its +length). Most of the examples are positive examples that you should +imitate. The few negative examples are clearly marked with a comment +of /* Yuck! */. Please don't submit code to cairo that looks like any +of these. + +Indentation +----------- +Each new level is indented 4 more spaces than the previous level: + + if (condition) + do_something (); + +This may be achieved with space characters or a combination of tab +characters and space characters. It may not be achieved with tab +characters exclusively (see below). + +Tab characters +-------------- +The tab character must always be interpreted according to its +traditional meaning: + + Advance to the next column which is a multiple of 8. + +With this definition, even levels of indentation can be achieved with +a sequence of tab characters, while odd levels of indentation may +begin with a sequence of tab character but must end with 4 space +characters. + +Some programmers have been misled by certain text editors into +thinking that 4-space indentation can be achieved with tab characters +exclusively by changing the meaning of tab character to be "advance to +the next column which is a multiple of 4". Code formatted in this way, +making an assumption of a fictitious 4-character-tab will not be +accepted into cairo. + +The rationale here is that tabs are used in the code for lining things +up other than indentation, (see the Whitespace section below), and +changing the interpretation of tab from its traditional meaning will +break this alignment. + +Braces +------ +Most of the code in cairo uses bracing in the style of K&R: + + if (condition) { + do_this (); + do_that (); + } else { + do_the_other (); + } + +but some of the code uses an alternate style: + + if (condition) + { + do_this (); + do_that (); + } + else + { + do_the_other (); + } + +and that seems just fine. We won't lay down any strict rule on this +point, (though there should be some local consistency). If you came +here hoping to find some guidance, then use the first form above. + +If all of the substatements of an if statement are single statements, +the optional braces should not usually appear: + + if (condition) + do_this (); + else + do_that (); + +But the braces are mandatory when mixing single statement and compound +statements in the various clauses. For example, do not do this: + + if (condition) { + do_this (); + do_that (); + } else /* Yuck! */ + do_the_other (); + +And of course, there are exceptions for when the code just looks +better with the braces: + + if (condition) { + /* Note that we have to be careful here. */ + do_something_dangerous (with_care); + } + + if (condition && + other_condition && + yet_another) + { + do_something (); + } + +And note that this last example also shows a situation in which the +opening brace really needs to be on its own line. The following looks awful: + + if (condition && + other_condition && + yet_another) { /* Yuck! */ + do_something (); + } + +As we said above, legible code that is easy to understand and maintain +is the goal, not adherence to strict rules. + +Whitespace +---------- +Separate logically distinct chunks with a single newline. This +obviously applies between functions, but also applies within a +function or block and can even be used to good effect within a +structure definition: + + struct _cairo_gstate { + cairo_operator_t op; + + double tolerance; + + /* stroke style */ + double line_width; + cairo_line_cap_t line_cap; + cairo_line_join_t line_join; + double miter_limit; + + cairo_fill_rule_t fill_rule; + + double *dash; + int num_dashes; + double dash_offset; + + ... + } + +Use a single space before a left parenthesis, except where the +standard will not allow it, (eg. when defining a parameterized macro). + +Don't eliminate newlines just because things would still fit on one +line. This breaks the expected visual structure of the code making it +much harder to read and understand: + + if (condition) foo (); else bar (); /* Yuck! */ + +Do eliminate trailing whitespace (space or tab characters) on any +line. Also, avoid putting initial or final blank lines into any file, +and never use multiple blank lines instead of a single blank line. + +Do enable the default git pre-commit hook that detect trailing +whitespace for you and help you to avoid corrupting cairo's tree with +it. Do that as follows: + + chmod a+x .git/hooks/pre-commit + +You might also find the git-stripspace utility helpful which acts as a +filter to remove trailing whitespace as well as initial, final, and +duplicate blank lines. + +As a special case of the bracing and whitespace guidelines, function +definitions should always take the following form: + + void + my_function (argument) + { + do_my_things (); + } + +And function prototypes should similarly have the return type (and +associated specifiers and qualifiers) on a line above the function, so +that the function name is flush left. + +Break up long lines (> ~80 characters) and use whitespace to align +things nicely. For example the arguments in a long list to a function +call should all be aligned with each other: + + align_function_arguments (argument_the_first, + argument_the_second, + argument_the_third); + +And as a special rule, in a function prototype, (as well as in the +definition), whitespace should be inserted between the parameter types +and names so that the names are aligned: + + void + align_parameter_names_in_prototypes (const char *char_star_arg, + int int_arg, + double *double_star_arg, + double double_arg); + +Note that parameters with a * prefix are aligned one character to the +left so that the actual names are aligned. + +Managing nested blocks +---------------------- +Long blocks that are deeply nested make the code very hard to +read. Fortunately such blocks often indicate logically distinct chunks +of functionality that are begging to be split into their own +functions. Please listen to the blocks when they beg. + +In other cases, gratuitous nesting comes about because the primary +functionality gets buried in a nested block rather than living at the +primary level where it belongs. Consider the following: + + foo = malloc (sizeof (foo_t)); + if (foo) { /* Yuck! */ + ... + /* lots of code to initialize foo */ + ... + return SUCCESS; + } + return FAILURE; + +This kind of gratuitous nesting can be avoided by following a pattern +of handling exceptional cases early and returning: + + foo = malloc (sizeof (foo_t)); + if (foo == NULL) + return FAILURE; + + ... + /* lots of code to initialize foo */ + ... + return SUCCESS; + +The return statement is often the best thing to use in a pattern like +this. If it's not available due to additional nesting above which +require some cleanup after the current block, then consider splitting +the current block into a new function before using goto. + +Memory allocation +----------------- + +Because much of cairo's data consists of dynamically allocated arrays, +it's very easy to introduce integer overflow issues whenever malloc() +is called. Use the _cairo_malloc2(), _cairo_malloc3(), and +_cairo_malloc2_add1 macros to avoid these cases; these macros check +for overflow and will return NULL in that case. + + malloc (n * size) => _cairo_malloc_ab (n, size) + e.g. malloc (num_elts * sizeof(some_type)) => + _cairo_malloc2 (num_elts, sizeof(some_type)) + + malloc (a * b * size) => _cairo_malloc_abc (a, b, size) + e.g. malloc (width * height * 4) => + _cairo_malloc3 (width, height, 4) + + malloc (n * size + k) => _cairo_malloc_ab_plus_c (n, size, k) + e.g. malloc (num * sizeof(entry) + sizeof(header)) => + _cairo_malloc2k (num, sizeof(entry), sizeof(header)) + +In general, be wary of performing any arithmetic operations in an +argument to malloc. You should explicitly check for integer overflow +yourself in any more complex situations. + +Mode lines +---------- + +So given the rules above, what is the best way to simplify one's life as +a code monkey? Get your editor to do most of the tedious work of +beautifying your code! + +As a reward for reading this far, here are some mode lines for the more +popular editors: +/* + * vim:sw=4:sts=4:ts=8:tw=78:fo=tcroq:cindent:cino=\:0,(0 + * vim:isk=a-z,A-Z,48-57,_,.,-,> + */ + + +TODO +---- + +Write rules for common editors to use this style.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations +below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it +becomes a de-facto standard. To achieve this, non-free programs must +be allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control +compilation and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at least + three years, to give the same user the materials specified in + Subsection 6a, above, for a charge no more than the cost of + performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply, and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License +may add an explicit geographical distribution limitation excluding those +countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change.

Distribution Obligations. + + 3.1. Application of License. + The Modifications which You create or to which You contribute are + governed by the terms of this License, including without limitation + Section 2.2. The Source Code version of Covered Code may be + distributed only under the terms of this License or a future version + of this License released under Section 6.1, and You must include a + copy of this License with every copy of the Source Code You + distribute. You may not offer or impose any terms on any Source Code + version that alters or restricts the applicable version of this + License or the recipients' rights hereunder. However, You may include + an additional document offering the additional rights described in + Section 3.5. + + 3.2. Availability of Source Code. + Any Modification which You create or to which You contribute must be + made available in Source Code form under the terms of this License + either on the same media as an Executable version or via an accepted + Electronic Distribution Mechanism to anyone to whom you made an + Executable version available; and if made available via Electronic + Distribution Mechanism, must remain available for at least twelve (12) + months after the date it initially became available, or at least six + (6) months after a subsequent version of that particular Modification + has been made available to such recipients. You are responsible for + ensuring that the Source Code version remains available even if the + Electronic Distribution Mechanism is maintained by a third party. + + 3.3. Description of Modifications. + You must cause all Covered Code to which You contribute to contain a + file documenting the changes You made to create that Covered Code and + the date of any change. You must include a prominent statement that + the Modification is derived, directly or indirectly, from Original + Code provided by the Initial Developer and including the name of the + Initial Developer in (a) the Source Code, and (b) in any notice in an + Executable version or related documentation in which You describe the + origin or ownership of the Covered Code. + + 3.4. Intellectual Property Matters + (a) Third Party Claims. + If Contributor has knowledge that a license under a third party's + intellectual property rights is required to exercise the rights + granted by such Contributor under Sections 2.1 or 2.2, + Contributor must include a text file with the Source Code + distribution titled "LEGAL" which describes the claim and the + party making the claim in sufficient detail that a recipient will + know whom to contact. If Contributor obtains such knowledge after + the Modification is made available as described in Section 3.2, + Contributor shall promptly modify the LEGAL file in all copies + Contributor makes available thereafter and shall take other steps + (such as notifying appropriate mailing lists or newsgroups) + reasonably calculated to inform those who received the Covered + Code that new knowledge has been obtained. + + (b) Contributor APIs. + If Contributor's Modifications include an application programming + interface and Contributor has knowledge of patent licenses which + are reasonably necessary to implement that API, Contributor must + also include this information in the LEGAL file. + + (c) Representations. + Contributor represents that, except as disclosed pursuant to + Section 3.4(a) above, Contributor believes that Contributor's + Modifications are Contributor's original creation(s) and/or + Contributor has sufficient rights to grant the rights conveyed by + this License. + + 3.5. Required Notices. + You must duplicate the notice in Exhibit A in each file of the Source + Code. If it is not possible to put such notice in a particular Source + Code file due to its structure, then You must include such notice in a + location (such as a relevant directory) where a user would be likely + to look for such a notice. If You created one or more Modification(s) + You may add your name as a Contributor to the notice described in + Exhibit A. You must also duplicate this License in any documentation + for the Source Code where You describe recipients' rights or ownership + rights relating to Covered Code. You may choose to offer, and to + charge a fee for, warranty, support, indemnity or liability + obligations to one or more recipients of Covered Code. However, You + may do so only on Your own behalf, and not on behalf of the Initial + Developer or any Contributor. You must make it absolutely clear than + any such warranty, support, indemnity or liability obligation is + offered by You alone, and You hereby agree to indemnify the Initial + Developer and every Contributor for any liability incurred by the + Initial Developer or such Contributor as a result of warranty, + support, indemnity or liability terms You offer. + + 3.6. Distribution of Executable Versions. + You may distribute Covered Code in Executable form only if the + requirements of Section 3.1-3.5 have been met for that Covered Code, + and if You include a notice stating that the Source Code version of + the Covered Code is available under the terms of this License, + including a description of how and where You have fulfilled the + obligations of Section 3.2. The notice must be conspicuously included + in any notice in an Executable version, related documentation or + collateral in which You describe recipients' rights relating to the + Covered Code. You may distribute the Executable version of Covered + Code or ownership rights under a license of Your choice, which may + contain terms different from this License, provided that You are in + compliance with the terms of this License and that the license for the + Executable version does not attempt to limit or alter the recipient's + rights in the Source Code version from the rights set forth in this + License. If You distribute the Executable version under a different + license You must make it absolutely clear that any terms which differ + from this License are offered by You alone, not by the Initial + Developer or any Contributor. You hereby agree to indemnify the + Initial Developer and every Contributor for any liability incurred by + the Initial Developer or such Contributor as a result of any such + terms You offer. + + 3.7. Larger Works. + You may create a Larger Work by combining Covered Code with other code + not governed by the terms of this License and distribute the Larger + Work as a single product. In such a case, You must make sure the + requirements of this License are fulfilled for the Covered Code. + +4. Inability to Comply Due to Statute or Regulation. + + If it is impossible for You to comply with any of the terms of this + License with respect to some or all of the Covered Code due to + statute, judicial order, or regulation then You must: (a) comply with + the terms of this License to the maximum extent possible; and (b) + describe the limitations and the code they affect. Such description + must be included in the LEGAL file described in Section 3.4 and must + be included with all distributions of the Source Code. Except to the + extent prohibited by statute or regulation, such description must be + sufficiently detailed for a recipient of ordinary skill to be able to + understand it. + +5. Application of this License. + + This License applies to code to which the Initial Developer has + attached the notice in Exhibit A and to related Covered Code. + +6. Versions of the License. + + 6.1. New Versions. + Netscape Communications Corporation ("Netscape") may publish revised + and/or new versions of the License from time to time. Each version + will be given a distinguishing version number. + + 6.2. Effect of New Versions. + Once Covered Code has been published under a particular version of the + License, You may always continue to use it under the terms of that + version. You may also choose to use such Covered Code under the terms + of any subsequent version of the License published by Netscape. No one + other than Netscape has the right to modify the terms applicable to + Covered Code created under this License. + + 6.3. Derivative Works. + If You create or use a modified version of this License (which you may + only do in order to apply it to code which is not already Covered Code + governed by this License), You must (a) rename Your license so that + the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape", + "MPL", "NPL" or any confusingly similar phrase do not appear in your + license (except to note that your license differs from this License) + and (b) otherwise make it clear that Your version of the license + contains terms which differ from the Mozilla Public License and + Netscape Public License. (Filling in the name of the Initial + Developer, Original Code or Contributor in the notice described in + Exhibit A shall not of themselves be deemed to be modifications of + this License.) + +7. DISCLAIMER OF WARRANTY. + + COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, + WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, + WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF + DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. + THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE + IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, + YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE + COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER + OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF + ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER. + +8. TERMINATION. + + 8.1. This License and the rights granted hereunder will terminate + automatically if You fail to comply with terms herein and fail to cure + such breach within 30 days of becoming aware of the breach. All + sublicenses to the Covered Code which are properly granted shall + survive any termination of this License. Provisions which, by their + nature, must remain in effect beyond the termination of this License + shall survive. + + 8.2. If You initiate litigation by asserting a patent infringement + claim (excluding declatory judgment actions) against Initial Developer + or a Contributor (the Initial Developer or Contributor against whom + You file such action is referred to as "Participant") alleging that: + + (a) such Participant's Contributor Version directly or indirectly + infringes any patent, then any and all rights granted by such + Participant to You under Sections 2.1 and/or 2.2 of this License + shall, upon 60 days notice from Participant terminate prospectively, + unless if within 60 days after receipt of notice You either: (i) + agree in writing to pay Participant a mutually agreeable reasonable + royalty for Your past and future use of Modifications made by such + Participant, or (ii) withdraw Your litigation claim with respect to + the Contributor Version against such Participant. If within 60 days + of notice, a reasonable royalty and payment arrangement are not + mutually agreed upon in writing by the parties or the litigation claim + is not withdrawn, the rights granted by Participant to You under + Sections 2.1 and/or 2.2 automatically terminate at the expiration of + the 60 day notice period specified above. + + (b) any software, hardware, or device, other than such Participant's + Contributor Version, directly or indirectly infringes any patent, then + any rights granted to You by such Participant under Sections 2.1(b) + and 2.2(b) are revoked effective as of the date You first made, used, + sold, distributed, or had made, Modifications made by that + Participant. + + 8.3. If You assert a patent infringement claim against Participant + alleging that such Participant's Contributor Version directly or + indirectly infringes any patent where such claim is resolved (such as + by license or settlement) prior to the initiation of patent + infringement litigation, then the reasonable value of the licenses + granted by such Participant under Sections 2.1 or 2.2 shall be taken + into account in determining the amount or value of any payment or + license. + + 8.4. In the event of termination under Sections 8.1 or 8.2 above, + all end user license agreements (excluding distributors and resellers) + which have been validly granted by You or any distributor hereunder + prior to termination shall survive termination. + +9. LIMITATION OF LIABILITY. + + UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT + (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL + DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, + OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR + ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY + CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, + WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER + COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN + INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF + LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY + RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW + PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE + EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO + THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU. + +10. U.S. GOVERNMENT END USERS. + + The Covered Code is a "commercial item," as that term is defined in + 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer + software" and "commercial computer software documentation," as such + terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 + C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), + all U.S. Government End Users acquire Covered Code with only those + rights set forth herein. + +11. MISCELLANEOUS. + + This License represents the complete agreement concerning subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the extent + necessary to make it enforceable. This License shall be governed by + California law provisions (except to the extent applicable law, if + any, provides otherwise), excluding its conflict-of-law provisions. + With respect to disputes in which at least one party is a citizen of, + or an entity chartered or registered to do business in the United + States of America, any litigation relating to this License shall be + subject to the jurisdiction of the Federal Courts of the Northern + District of California, with venue lying in Santa Clara County, + California, with the losing party responsible for costs, including + without limitation, court costs and reasonable attorneys' fees and + expenses. The application of the United Nations Convention on + Contracts for the International Sale of Goods is expressly excluded. + Any law or regulation which provides that the language of a contract + shall be construed against the drafter shall not apply to this + License. + +12. RESPONSIBILITY FOR CLAIMS. + + As between Initial Developer and the Contributors, each party is + responsible for claims and damages arising, directly or indirectly, + out of its utilization of rights under this License and You agree to + work with Initial Developer and Contributors to distribute such + responsibility on an equitable basis. Nothing herein is intended or + shall be deemed to constitute any admission of liability. + +13. MULTIPLE-LICENSED CODE. + + Initial Developer may designate portions of the Covered Code as + "Multiple-Licensed".

The sampling and reconstruction kernels are picked in a way that + gives comparable quality when upscaling and downscaling.

Or maybe + > differentiate between NEAREST and FAST in that case? + + If impulse (point) sampling is used, there must be some reconstruction + filter, otherwise no image is produced. That's because the sampling + grid does not match the data grid, and since there is no + reconstruction filter, values between data points are undefined. The + alternative is to use box sampling + no reconstruction. + + 2. Subsampling bits are always set to 1, since this doesn't seem to + affect quality at all. + + 3.

down into the backends. The motivation for this is that not all backends want a surface for the source operand, and by passing the pattern down, backends can choose to convert it to a surface if they need that. + The patch removes the create_surface function pointer from the surface vtable and moves much of that code into a couple of helper functions. The composite, compsite_trapezoids, and show_glyphs backend functions are updated to take a cairo_pattern_t instead of a surface as the source. + Change these functions to not create a surface for the pattern and just pass the pattern down to the backend functions. + New function to translate a set of trapezoids. + Break out the code to adjust and restore surface transformation and repeat settings into _cairo_pattern_prepare_surface and _cairo_pattern_restore_surface. + Split cairo_pattern_create_for_surface into an init function and a create function. + Utility functions to create a surface from a pattern. + Update these backends to work with the new pattern API.

backend + + The rationale behind this change is that when someone is trying to + draw on a SVG surface using image surface patterns, the resulting SVG + file can take up to ridiculous 20 megabytes for 3-4 typical + photographic images in a single SVG file. This also can take + significant amount of CPU time to complete. + + The reason for this behaviour is that currently whenever SVG backend + needs to emit an image tag for a surface pattern it takes a snapshot + of the subject surface, encodes it in PNG, then Base64-encodes and + emits the (huge) resulting string. With use of + cairo_surface_set_mime_data API this can be somewhat improved by + associating JPEG image contents with the corresponding surfaces. + Still this doesn't allow for post-processing of involved photographic + images without regenerating the SVG file. + + As SVG specification allows URIs in the image tag's xlink:href + attribute, it is possible instead of embedding encoded image data to + simply link image files residing physically on the same medium as the + generated SVG file: files on disk under common directory, files on a + web server at common base URI, etc. + + To make this happen we add new (unofficial) MIME type "text/x-uri" and + let users associate URIs with surfaces through + cairo_surface_set_mime_data() API. When SVG backend needs to emit + surface contents and it sees "text/x-uri" attached to the surface, it + emits this data instead of taking snapshot. The URI data is emitted + as is, so correctness check is left solely to the client code. + + doc/public/cairo-sections.txt | 1 + + doc/public/tmpl/cairo-surface.sgml | 7 ++++ + src/cairo-surface.c | 16 ++++++++- + src/cairo-svg-surface.c | 72 +++++++++++++++++++++++++++++++++++--- + src/cairo.h | 1 + + 5 files changed, 92 insertions(+), 5 deletions(-) + +commit d91bab565c54205f8dd7aa8a9de819dc4bc3551c +Author: Chris Wilson <chris@chris-wilson.co.uk> +Date: Tue Mar 2 08:12:52 2010 +0000 + + test: Remove the double-clip from clip-group-shapes + + A push/pop is an implicit save/restore, so a clip applied inside the + group is temporary, whereas a clip applied outside affects both the + geometry inside *and* the application of the group when painted.

For example, the clip must be copied from the surface + onto the fallback image, but this was forgotten causing undue hassle in + each backend. Another example is the contortion the meta surface + endures to ensure the clip is correctly recorded. By contrast passing the + clip along with the operation is quite simple and enables us to write + generic handlers for providing surface wrappers. (And in the future, we + should be able to write more esoteric wrappers, e.g. automatic 2x FSAA, + trivially.) + + In brief, instead of the surface automatically applying the clip before + calling the backend, the backend can call into a generic helper to apply + clipping. For raster surfaces, clip regions are handled automatically as + part of the composite interface. For vector surfaces, a clip helper is + introduced to replay and callback into an intersect_clip_path() function + as necessary. + + Whilst this is not primarily a performance related change (the change + should just move the computation of the clip from the moment it is applied + by the user to the moment it is required by the backend), it is important + to track any potential regression: + +

The tessellations can survive + translations and rotations increasing the probability that they can be + re-used. + - sources and masks are handled using multi-texturing. + - clipping is handled with a scissor and the stencil buffer which + we're careful to only update when they really change. + - linear gradients are rendered to a 1d texture using a triangle + strip + interpolating color attributes.

fcea0f8e08e2fbd448a990b60be0cf16535b45a5 +Author: Chris Wilson <chris@chris-wilson.co.uk> +Date: Fri Sep 16 11:09:22 2011 +0100 + + test: Use the test-traps as the reference images for xlib/xcb + + The test-traps provides a reference implementation of the + traps-compositor as used by xlib, so we can use it to generate the + reference images as well. (Of course checking that test-traps is itself + correct and only differs in the renderer! ;-) + + Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> + +

Now, all 5 operations have backend functions, and all use a consistent convention for argument naming and ordering. The old fill_path has been replaced with a new fill. The old show_glyphs function was recently renamed to old_show_glyphs and has not yet been ported to the new show_glyphs, (so all backends have a NULL show_glyphs function). In fact, of the 5 new backend functions, fill is the only one that has an implementation in any backend.

This is necessarily (as opposed to just + casting to target type) because the two types may not be "compatible" from the + compiler's point of view. Example of types that are not compatbile is structs + vs anything. + + The "dereferencing type-punned pointer will break strict-aliasing rules" from + gcc exactly means: "some code may be assuming that pointers with different + types do not compare equal (or otherwise share the same target object). If + you case a pointer to a different type and dereference it, it may happen + here." However, in our usecase, it's clear that the compiler cannot make any + false assumptions. So we just go ahead and hide it by using a middle cast to + "void *". Since the compiler does not many any aliasing assumptions about + generic pointers, it will not warn either. (Though the problems if any, will + still occure. So this is not an ideal solution to this problem and should be + used very carefully, to no hide useful warnings for when things go loose on + some weird architecture.) + + Another solution would have been to use gcc's "may_alias" function attribute, + but trying to define a may_alias version of __m64 hit a bug in gcc. That is, + try replacing "__m64" with "m64" and define: + + typedef __m64 m64 __attribute__((may_alias)); + + and see it fail to compile.

The PDF file is using character code 0 (glyph 0 due to + Identity-H encoding) as a space character. The CFF specification + defines glyph 0 to be the .notdef glyph. + + The PS backend subsets CFF fonts as a Type1-fallback + font. Type1-fallback creates it's own empty .notdef glyph with an + arbitrary glyph advance of 500. The problem here is the TJ operator + used to output the glyphs depends on the glyph advance being + correct. pdf-operators.c uses the glyph advance returned by + _scaled_glyph_init(). However the PostScript interpreter sees the + glyph advance of 500 for .notdef. This problem does not occur when + generating PDF as the PDF font dictionary contains an list of glyph + advances that override the font metrics. + + Fix this by making Type1-fallback not treat .notdef as special and to + create it the path and metrics obtained from _scaled_glyph_init(). As + a special case, make it not fail if _scaled_glyph_init() is unable to + return a path for .notdef. This was probably the reason Type1-fallback + previously created it's own .notdef glyph as calling + _scaled_glyph_init(_GLYPH_INFO_PATH) for glyph 0 returns + CAIRO_INT_STATUS_UNSUPPORTED for some fonts. + + This ensures the Type1-fallback font metrics match the metrics used + by pdf-operators.c to position the glyphs.

Here is all the math(!): + + A device_transform converts from device space (a conceptual space) to + surface space. For simple cases of translation only, it's called a + device_offset and is public API (cairo_surface_[gs]et_device_offset). + A possibly better name for those functions could have been + cairo_surface_[gs]et_origing. So, that's what they do: they set where + the device-space origin (0,0) is in the surface. If the origin is inside + the surface, device_offset values are positive.

In these + cases device_offset is typically negative. Example: + + application window + +---------------+ + | . | + | (x,y). | + |......+---+ | + | | | <--|-- expose area + | +---+ | + +---------------+ + + In this case, the user of cairo API can set the device_space on + the expose area to (-x,-y) to move the device space origin to that + of the application window, such that drawing in the expose area + surface and painting it in the application window has the same + effect as drawing in the application window directly. Gtk+ has + been using this feature. + + - Glyph surfaces: In most font rendering systems, glyph surfaces + have an origin at (0,0) and a bounding box that is typically + represented as (x_bearing,y_bearing,width,height). Depending on + which way y progresses in the system, y_bearing may typically be + negative (for systems similar to cairo, with origin at top left), + or be positive (in systems like PDF with origin at bottom left). + No matter which is the case, it is important to note that + (x_bearing,y_bearing) is the coordinates of top-left of the glyph + relative to the glyph origin. That is, for example: + + Scaled-glyph space: + + (x_bearing,y_bearing) <-- negative numbers + +----------------+ + | . | + | . | + |......(0,0) <---|-- glyph origin + | | + | | + +----------------+ + (width+x_bearing,height+y_bearing) + + Note the similarity of the origin to the device space. That is + exactly how we use the device_offset to represent scaled glyphs: + to use the device-space origin as the glyph origin. + + Now compare the scaled-glyph space to device-space and surface-space + and convince yourself that: + + (x_bearing,y_bearing) = (-x,-y) = - device_offset + + That's right. If you are not convinced yet, contrast the definition + of the two: + + "(x_bearing,y_bearing) is the coordinates of top-left of the + glyph relative to the glyph origin." + + "In other words: device_offset is the coordinates of the + device-space origin relative to the top-left of the surface." + + and note that glyph origin = device-space origin. + + So, that was the bug. Fixing it removed lots of wonders and magic + negation signs. + + The way I discovered the bug was that in the user-font API, to make + rendering the glyph from meta-surface to an image-surface work I had + to do: + + cairo_surface_set_device_offset (surface, -x_bearing, -y_bearing); + _cairo_meta_surface_replay (meta_surface, surface); + cairo_surface_set_device_offset (surface, x_bearing, y_bearing); + + This suggested that the use of device_offset for glyph origin is + different from its use for rendering with meta-surface. This reminded + me of the large comment in the xlib backend blaming XRender for having + weird glyph space, and of a similar problem I had in the PS backend + for bitmap glyph positioning (see d47388ad759b0a1a0869655a87d9b5eb6ae2445d) + + ...those are all fixed now. + + src/cairo-atsui-font.c | 4 ++-- + src/cairo-directfb-surface.c | 4 ++-- + src/cairo-ft-font.c | 46 +++++++++++++++++++++++--------------------- + src/cairo-glitz-surface.c | 8 ++++---- + src/cairo-ps-surface.c | 12 ++++++------ + src/cairo-scaled-font.c | 8 +++----- + src/cairo-svg-surface.c | 2 +- + src/cairo-xcb-surface.c | 40 ++------------------------------------ + src/cairo-xlib-surface.c | 40 ++------------------------------------ + 9 files changed, 46 insertions(+), 118 deletions(-) + +commit d55da1aa621d76b1411300932be5d37883b25dfa +Author: Behdad Esfahbod <behdad@behdad.org> +Date: Wed Feb 7 00:20:29 2007 -0800 + + [scaled-font] Really ignore ctm translation + + Previously we were ignoring ctm translation in scaled fonts when hashing, but + still storing it into the scaled font.

That's like going utf8 forward. + + On the other hand, if we are fine doing glyphs backward, then we may as + well remove the "backward" flag and ask callers of show_text_glyphs to + produce glyph array going right to left for RTL runs. The idea behind + having a backward flag in the first place was to allow keeping utf8 in + logical order and glyphs in visual left-to-right order. If we don't + do that in practice, there's no point in having the flag. Another design + idea of the flag was to mark right-to-left runs explicitly so the backend + can use this information. In that case we probably better rename it to + "rtl" as the current semantics make it perfectly fine to set a LTR segment + with backward flag on: just revers the glyph array... + + Anyway, the way to determine the right thing to do is to see how Acrobat + extracts text for RTL text in logical vs visual order.

See: + + http://cairographics.org/download/ + +For more information on using git, see: + + http://freedesktop.org/wiki/Infrastructure/git/ + + +Build System +------------ + +We use the autotools build system with cairo, but with various +customizations and advanced features. Reading configure.in is your +best bet to understanding it, or just ask on IRC. + +To bootstrap the build system run ./autogen.sh. After that the +regular "./configure; make; make install" sequence can be used. +See file named INSTALL for more details. + +There is limited support for a win32 build system. +See README.win32 and Makefile.win32 files in various directories. + + +ChangeLog +--------- + +We generate ChangeLog files automatically from the git commit log. +No manual ChangeLog writing is necessary. + + +Copyrights and Licensing +------------------------ + +The cairo library is dual-licensed under LGPL and MPL. See the file +named COPYING for details. The test suites are more liberal, and are +allowed to include GPL code. + +When writing new code, update the file headers to add your (or your +employers) copyright line and contributor line. If adding new files +or splitting a file, copy the file header from other files. + + +Source Code +----------- + +The library source code and headers live in the src/ directory. +See src/README for more information. + + +Regression Test Suite +--------------------- + +Cairo has a fairly extensive regression-testing suite. Indeed, without +these tests it would be impossible to make a cairo release without +introducing tens of regressions. We still manage to introduce +regressions with each release even with the hundreds of tests we already +have. + +The regression test suite is located under the test/ directory. +See test/README for more information. + + +Performance Test Suite +---------------------- + +There is a performance test suite located under the perf/ directory. +A collection of traces of real-world behavior are also available in the +cairo-traces repository, which can be used in isolation or hooked in +with the main performance test suite. See perf/README for more +information. + + +Boilerplate +----------- + +The cairo-boilerplate is a small private library used by the regression +and performance test suites. It includes the boilerplace code needed +to initialize various backends for the test suites, as well as allow +tweaking some of the internal workings of the backends for more testing. + +The boilerplate code is localted under the boilerplate/ directory. +See boilerplate/README for more information. + + +Documentation +------------- + +Cairo uses the gtk-doc system for reference API documentation. + +The reference documentation is located under doc/public. +See doc/public/README for more information. + +For more documentation including frequently asked questions, tutorials, +samples, roadmap, todo list, etc visit: + + http://cairographics.org/documentation/ + +Some of those should gradually be moved to doc/. + + +Utilities +--------- + +We have developed several utilities useful for writing cairo or code +that uses cairo. These tools can be found under the util/ directory. +See util/README for more information. + + +Releasing +--------- + +Now you are a cairo maintainer, so what?

[Note: if you don't have a configure + script, skip down below to the Extremely detailed build + instructions.] + + The configure script attempts to automatically detect as much as + possible about your system. So, you should primarily just accept + its defaults by running: + + ./configure + + The configure script does accept a large number of options for + fine-tuning its behavior. See "./configure --help" for a complete + list. The most commonly used options are discussed here. + + --prefix=PREFIX + + This option specifies the directory under which the software + should be installed. By default configure will choose a + directory such as /usr/local. If you would like to install + cairo to some other location, pass the director to configure + with the --prefix option. For example: + + ./configure --prefix=/opt/cairo + + would install cairo into the /opt/cairo directory. You could + also choose a prefix directory within your home directory if + you don't have write access to any system-wide directory. + + After installing into a custom prefix, you will need to set + some environment variables to allow the software to be + found. Assuming the /opt/cairo prefix and assuming you are + using the bash shell, the following environment variables + should be set: + + PKG_CONFIG_PATH=/opt/cairo/lib/pkgconfig + LD_LIBRARY_PATH=/opt/cairo/lib + export PKG_CONFIG_PATH LD_LIBRARY_PATH + + (NOTE: On Mac OS X, at least, use DYLD_LIBRARY_PATH in place + of LD_LIBRARY_PATH above.) + + --enable-XYZ + --enable-XYZ=yes + --enable-XYZ=auto + --enable-XYZ=no + --disable-XYZ + + Cairo's various font and surface backends and other features can be + enabled or disabled at configure time. Features can be divided into + three categories based on their default state: + + * default=yes: These are the recommended features like PNG functions + and PS/PDF/SVG backends. It is highly recommended to not disable + these features but if that's really what one wants, they can be + disabled using --disable-XYZ. + + * default=auto: These are the "native" features, that is, they are + platform specific, like the Xlib surface backend. You probably + want one or two of these. They will be automatically enabled if + all their required facilities are available. Or you can use + --enable-XYZ or --disable-XYZ to make your desire clear, and then + cairo errs during configure if your intention cannot be followed. + + * default=no: These are the "experimental" features, and hence by + default off. Use --enabled-XYZ to enable them. + + The list of all features and their default state can be seen in the + output of ./configure --help. + +2) Compile the package: + + This step is very simple. Just: + + make + + The Makefiles included with cairo are designed to work on as many + different systems as possible. + + When cairo is compiled, you can also run some automated tests of + cairo with: + + make check + + NOTE: Some versions of X servers will cause the -xlib tests to + report failures in make check even when cairo is working just + fine. If you see failures in nothing but -xlib tests, please + examine the corresponding -xlib-out.png images and compare them to + the -ref.png reference images (the -xlib-diff.png images might also + be useful). If the results seem "close enough" please do not report + a bug against cairo as the "failures" you are seeing are just due + to subtle variations in X server implementations. + +3) Install the package: + + The final step is to install the package with: + + make install + + If you are installing to a system-wide location you may need to + temporarily acquire root access in order to perform this + operation. A good way to do this is to use the sudo program: + + sudo make install + +Extremely detailed build instructions +------------------------------------- +So you want to build cairo but it didn't come with a configure +script. This is probably because you have checked out the latest +in-development code via git. If you need to be on the bleeding edge, +(for example, because you're wanting to develop some aspect of cairo +itself), then you're in the right place and should read on. + +However, if you don't need such a bleeding-edge version of cairo, then +you might prefer to start by building the latest stable cairo release: + + http://cairographics.org/releases + +or perhaps the latest (unstable) development snapshot: + + http://cairographics.org/snapshots + +There you'll find nicely packaged tar files that include a configure +script so you can go back the the simpler instructions above. + +But you're still reading, so you're someone that loves to +learn. Excellent! We hope you'll learn enough to make some excellent +contributions to cairo. Since you're not using a packaged tar file, +you're going to need some additional tools beyond just a C compiler in +order to compile cairo. Specifically, you need the following utilities: + + automake + autoconf + autoheader + aclocal + libtoolize + pkg-config [at least version 0.16] + gtk-doc (recommended) + +Hopefully your platform of choice has packages readily available so +that you can easily install things with your system's package +management tool, (such as "apt-get install automake" on Debian or "yum +install automake" on Fedora, etc.). Note that Mac OS X ships with +glibtoolize instead of libtoolize. + +Once you have all of those packages installed, the next step is to run +the autogen.sh script. That can be as simple as: + + ./autogen.sh + +But before you run that command, note that the autogen.sh script +accepts all the same arguments as the configure script, (and in fact, +will generate the configure script and run it with the arguments you +provide). So go back up to step (1) above and see what additional +arguments you might want to pass, (such as prefix). Then continue with +the instructions, simply using ./autogen.sh in place of ./configure. + +Happy hacking! diff --git a/KNOWN_ISSUES b/KNOWN_ISSUES new file mode 100644 index 000000000..c367f918e --- /dev/null +++ b/KNOWN_ISSUES @@ -0,0 +1,3 @@ +Known Issues +------------ +None diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 000000000..03fa35236 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,83 @@ +include $(top_srcdir)/build/Makefile.am.common + +EXTRA_DIST += \ + KNOWN_ISSUES \ + README.win32 \ + Makefile.win32 \ + build/Makefile.win32.common \ + build/Makefile.win32.inform \ + build/Makefile.win32.features \ + build/Makefile.win32.features-h \ + $(NULL) +#MAINTAINERCLEANFILES += \ +# $(srcdir)/build/Makefile.win32.features \ +# $(srcdir)/build/Makefile.win32.features-h \ +# $(NULL) + +ACLOCAL_AMFLAGS = -I build ${ACLOCAL_FLAGS} + +DIST_SUBDIRS = src doc util boilerplate test perf +SUBDIRS = src doc util +# libpng is required for our test programs +if CAIRO_HAS_PNG_FUNCTIONS +SUBDIRS += boilerplate test perf +endif + +configure: cairo-version.h + +doc: + cd doc && $(MAKE) $(AM_MAKEFLAGS) $@ +test retest recheck: all + cd test && $(MAKE) $(AM_MAKEFLAGS) $@ +perf: all + cd perf && $(MAKE) $(AM_MAKEFLAGS) $@ +check-valgrind: all + cd test && $(MAKE) $(AM_MAKEFLAGS) check-valgrind + cd perf && $(MAKE) $(AM_MAKEFLAGS) check-valgrind +.PHONY: doc test retest recheck perf check-valgrind + + +EXTRA_DIST += \ + AUTHORS \ + BIBLIOGRAPHY \ + BUGS \ + CODING_STYLE \ + COPYING \ + COPYING-LGPL-2.1 \ + COPYING-MPL-1.1 \ + HACKING \ + INSTALL \ + NEWS \ + PORTING_GUIDE \ + README \ + RELEASING \ + autogen.sh \ + cairo-version.h \ + $(NULL) + +DISTCLEANFILES += config.cache + +MAINTAINERCLEANFILES += \ + $(srcdir)/aclocal.m4 \ + $(srcdir)/autoscan.log \ + $(srcdir)/build/compile \ + $(srcdir)/build/config.guess \ + $(srcdir)/build/config.sub \ + $(srcdir)/build/depcomp \ + $(srcdir)/build/install-sh \ + $(srcdir)/build/ltmain.sh \ + $(srcdir)/build/missing \ + $(srcdir)/build/mkinstalldirs \ + $(srcdir)/config.h.in \ + $(srcdir)/configure.scan \ + $(NULL) + +DISTCHECK_CONFIGURE_FLAGS = \ + --enable-gtk-doc \ + --enable-test-surfaces \ + --enable-full-testing \ + $(NULL) + +include $(srcdir)/build/Makefile.am.changelog +include $(srcdir)/build/Makefile.am.releasing +include $(srcdir)/build/Makefile.am.analysis diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 000000000..5ceb0f886 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,1742 @@ +# Makefile.in generated by automake 1.14.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2013 Free Software Foundation, Inc. + +# This Makefile.in is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +@SET_MAKE@ + +# Creating ChangeLog files from git log: + +# We always create a ChangeLog that contains the most recent changes, and +# multiple others for changes between major releases (other than the last such +# segment that we put in 'ChangeLog'.

Platforms with fixes include Sparc, AIX, Windows +(mingw), and Windows (MSVC8). Memory leaks, valgrind issues, and PDF +issues round out our list. + +It's come to light that changes in cairo 1.14 resulted in breakage on +MacOS X 10.4. We've not yet determined whether to fix up the support, +or excise the 10.4-specific code and support only OS X 10.5 or newer. +Meantime, we'll only advertise cairo as working on OS X 10.5. + +Features +-------- + * Improve xcb's handling of per-screen subpixel ordering. If no + Xft.rgba property is specified, default to the screen's subpixel + order. + +API Changes +----------- +None + +Dependency Changes +------------------ +None + +Performance Optimizations +------------------------- + * Improve performance of cpu_to_be32 and be32_to_cpu, making truetype + subsetting of large fonts run about 15% faster. + +Bug Fixes +--------- + * Fix unaligned access on sparc with the compact font format (CFF). + Unlike truetype, all data in CFF is not aligned. + (Debian bug #712836) + * Fix unaligned access on sparc with tor-scan-converter's memory pool. + * Fix crash when loading a PDF with a transformed image. + (fdo bug #85151) + * Fix regression on mingw for bigendian test due to removal of file + extension for executables. + (fdo bug #85120) + * Fix handling of backslash in PDF interpreter + (fdo bug #85662) + * Fix crash in xlib and xcb renderers when swapping a 0-sized glyph + * Fix bug with RTL text in PDF operators + (fdo bug #86461) + * Fix compilation 'cairo-path-stroke-traps.c' with MSVC8 + (fdo bug #84908) + * Fix crash in _fill_xrgb32_lerp_opaque_spans when a span length is + negative. + * Fix valgrind error by releasing pattern created by + cairo_pattern_create_rgb(). + * Fix valgrind errors when running cairo-test-suite. + * Fix memory leak in recording surface replays + (fdo bug #87898) + * Fix destruction of fonts in api-special-cases test. + (fdo bug #87567) + * Fix duplicated surface push on similar-image, preventing trivial GTK3 + program traces from being replayable, with an error message about + invalid values for the size of the input. + (fdo bug #73580) + * Fix crash when win32 surface's image size does not cover the entire + surface. + (fdo bug #53121) + * Fix crash due to obsolete CGFontGetGlyphPath call + (fdo bug #84324) + * Fix several build issues on AIX + (fdo bugs #89338, #89340, #89356, #89354) + * Fix various documentation warnings and errors + +Release 1.14.0 (2014-10-13 Bryce Harrington <bryce@osg.samsung.com>) +==================================================================== +Hard to believe it's been over a year since our last release, but it's +not for lack of activity. This release includes contributions of a wide +assortment of bug fixes, build system improvements, warnings cleanups, +codebase refactoring, test suite repairs, and static analysis work. + +This release is lighter on features (compared with 1.12.10) but includes +a highly demanded rehaul of our image downscaling functionality, which +solves a serious problem experienced by Inkscape users when shrinking +embedded bitmaps in SVG files. The new scaling algorithms are used by +the image backend and by other backends as needed for fallbacks. + + +Features +-------- + + Filtering improvements for the image backend, in particular + down-scaling of images produces filtered images that depend on all the + pixels of the source. When using the image backend you get the + following settings: + + CAIRO_FILTER_GOOD: uses a box filter for scales less than .75 in + either direction. For scales larger than this, the same filter as + CAIRO_FILTER_BILINEAR is used. + + CAIRO_FILTER_BEST: uses a Catmull-Rom filter always. When upscaling + more than 2x this will produce anti-aliased square pixels, similar + to OS/X. + + CAIRO_FILTER_GAUSSIAN: uses PIXMAN_FILTER_BEST, which in current + pixman is the same as BILINEAR. (This is subject to change in the + future). + + xlib and xcb also use the image fallback for GOOD/BEST filters, but + note that other backends do not implement these filtering fixes yet, + however other actions may cause them to use an image fallback which + will cause these filters to be used. + + Improve handling of device transformation and scaling, allowing Cairo + to now support scaling at a device level, permitting easier, more + transparent HiDPI support. + + Support JBIG2 mime data in PDF. This allows embedding of more + compressed JPEG formats within PDF, rather than including the full + uncompressed image. Also, reduce the number of transparency groups + used by PDF to keep the file size small and viewing/printing of the + PDF fast. + + Expand the embedding section to include stencil mask support. + + Reorder font declarations to be in natural order. + + Update the Skia backend to build against current Skia (as of June + 2014). + + Drop Link-Time Optimization (LTO) support from build system. This + seems to have caused much trouble for unclear benefit, and most + distros are reverting or disabling it anyway. + + Optimize VBO size on GL to 1M and to 16k for EGL. This improves + (theoretical) performance for desktop GLX use cases while avoiding + hitting VBO memory size limitations on embedded devices. + +API Changes +----------- + + cairo_surface_set_device_scale, cairo_surface_get_device_scale: + + Sets a scale that is multiplied to the device coordinates + determined by the CTM when drawing to @surface. One common use for + this is to render to very high resolution display devices at a scale + factor, so that code that assumes 1 pixel will be a certain size + will still work. + + cairo_egl_device_get_display, cairo_egl_device_get_context: + + Support get/set of EGLContext and EGLDisplay for egl-based cairo + devices, similar to GLX. + +Dependency Changes +------------------ + + Cairo now requires glib 2.14 for its gobject helper functions, + and pixman 0.30 for downscaling. + + +Bug fixes +--------- + + Don't embed CMYK Jpeg images in svg. + + Fix tests to place output in proper location. + + Fix determination of alpha for all surfaces when recording. + + Extend oversize check to cairo_gl_surface_create_for_texture, so an + error surface is returned if the texture is too large to render to. + + Fix embedding of mime data in PDF and PS files. + + Remove useless error handling in *_reply() functions in XCB. + + Fix a double-free exposed by multithreaded apps creating and + destroying the same font concurrently. + https://bugs.freedesktop.org/show_bug.cgi?id=69470 + + Fix corrupt stacks produced by bugs in operand emission for trace. + + Fix out of bounds array access in format cache for xlib + + Don't rename glyphs used by seac operator. This can cause certain + combined characters to use their decorations (e.g. umlauts on ö) to be + lost during printing of PDFs using evince. + https://bugs.freedesktop.org/show_bug.cgi?id=70364 + + Fix crash on calling cairo_create with a finished surface + + Fix SSIZE_T definition problem when making with MSYS on Windows7 + + Fix one off issue in gl context cleanup + + Fix usage of CAIRO_STACK_ARRAY_LENGTH + + Fix rectangle stroke with non rectilinear pen + + Fix imagemask with pattern source failure on some printers.

Note that there are still a few + regressions remaining. + + +Release 1.12.8 (2012-11-24 Chris Wilson <chris@chris-wilson.co.uk>) +=================================================================== +Another couple of weeks and a few more bugs have been found and fixed, +it is time to push the next point release. Many thanks to everyone who +reported their issues and helped us track down the bugs and helped +testing the fixes. + +Bug fixes +--------- + + Expand the sanity checking for broken combinations of XSendEvent and + ShmCompletionEvent. + + Notice that "The X.Org Foundation" sometimes also identifies itself + as "The Xorg Foundation". + + Handle various ages of libXext and its Shm headers. + + Fix the invalid clipping of the source drawable when using SHM + transport to upload images. + https://bugs.freedesktop.org/show_bug.cgi?id=56547 + + Handle all Type1 postscript operators for better font compatibility. + https://bugs.freedesktop.org/show_bug.cgi?id=56265 + + Fix a couple of memory leaks in Type1 font subsetting + https://bugs.freedesktop.org/show_bug.cgi?id=56566 + + Tighten the evaluation of the start/stop pen vertices, and catch a few + instances where we would use a fan instead of a bevel. + https://bugs.freedesktop.org/show_bug.cgi?id=56432 + + Fix assumption that geometric clipping always succeeds with the + span-compositor. + https://bugs.freedesktop.org/show_bug.cgi?id=56574 + + Fix call to spline intersection when evaluating whether a stoke is + visible. + + Remember to copy inferior sources when using SHM to readback the + surface for use as a source. + +Release 1.12.6 (2012-10-22 Chris Wilson <chris@chris-wilson.co.uk>) +=================================================================== +Thanks to everyone who download cairo-1.12.4 and gave us their feedback. +It truly was invaluable and has helped us to fix many portability issues +that crept in with some of the new features. This release aims to fix +those stability issues and run on a wider range of systems. + +Bug fixes +--------- + + Fix the recording surface to actually snapshot the source and so fix + PDF drawing. + + Calling XSendEvent with an XShmCompletionEvent is incompatabile with + older Xorg servers. + + Reorder CloseDisplay chain so that XShm is not reinstantiated after + shutdown, causing a potential crash if the Display was immediately + recreated using the same memory address. + + Make sure that the Xserver has attached to the SHM segment before + deleting it from the global namespace on systems that do not support + deferred deletion. + + Type1 subsetting support for PDF (and PS) was once again improved to + work with a larger number of PDF readers. + + GLESv2 build fixes and improved support for embedded GPUs. + + Tweak the invisible pen detection for applications that are currently + using too large values for geometric tolerance. + + A build fix for older freetype libraries. + + +Release 1.12.4 (2012-10-05 Chris Wilson <chris@chris-wilson.co.uk>) +=================================================================== +More bugs, and more importantly, more fixes. On the cairo-gl side, we +have refinements to the MSAA compositor which enables hardware +acceleration of comparitively low-quality antialiasing - which is useful +in animations and on very high density screens. For cairo-xlib, we have +finally enabled SHM transport for image transfers to and from the X +server. A long standing required feature, SHM transport offers a notable +reduction in rendering latency by reducing the number of copies +required to upload image data - given hardware and driver support, +cairo-xlib can now perform zero copy uploads onto the GPU. And as usual +Adrian Johnson has been very busy fixing many different corner cases in +cairo-pdf, impoving opacity groups and font subsetting. Last, but not +least, for cairo-image Søren Sandmann Pedersen added support for +rendering glyphs to pixman and using that from within cairo. The new +glyph rendering facility reduces the overhead for setting up the +compositing operation, improving glyph thoughput for the image backend +by a factor of about 4. And before he did so, he also fixed up a few +bugs in the existing glyph rendering code. So many thanks to Andrea +Canciani, Adrian Johnson, Chuanbo Weng, Dongyeon Kim, Henry Song, Martin +Robinson, Søren Sandmann Pedersen and Uli Schlachter for their +contributions, finding and fixing bugs. + +Bug fixes +--------- + + Interior boxes were being dropped when amalgamating regions during + tesselation. + https://bugs.freedesktop.org/show_bug.cgi?id=49446 + + Allow building without gtk-doc installed + + Invalid edge generation whilst reducing complex polygons. + https://bugs.freedesktop.org/show_bug.cgi?id=50852 + + Stroking around tight cusps + + Use locale correct formats for reading font subsetting and valid + buffers. + https://bugs.freedesktop.org/show_bug.cgi?id=51443 + + Ensure that the type1 subset includes all the glyph encodings + https://bugs.freedesktop.org/show_bug.cgi?id=53040 + + Upload the whole source for a repeating pattern. + https://bugs.freedesktop.org/show_bug.cgi?id=51910 + + Fix damage tracking to handle continuation chunks corectly and so + prevent crashes on win32. + https://bugs.freedesktop.org/show_bug.cgi?id=53384 + + Avoid emitting miter joins for degenerate line segments + https://bugzilla.mozilla.org/show_bug.cgi?id=407107 + + Convert the relative path semgents into the backend coordinates + and then back again to user coordinates (cairo_copy_path, + cairo_append_path) + https://bugs.freedesktop.org/show_bug.cgi?id=54732 + + Fix extents computations for a degenerate path consisting only of a + move-to + https://bugs.freedesktop.org/show_bug.cgi?id=54549 + + Prevent crashing on a degenerate project edge after polygon + intersection + https://bugs.freedesktop.org/show_bug.cgi?id=54822 + + + +Release 1.12.2 (2012-04-29 Chris Wilson <chris@chris-wilson.co.uk>) +=================================================================== +After such a long gestation period for the release of Cairo 1.12, we +inevitably accumulated a few bugs that were flushed out by broadening the +test base. Thanks to everybody who tried the release, apologies to any one +unfortunate enough to encounter a bug and many thanks for reporting it. As +a result Adrian Johnson, Alexandros Frantzis, Andrea Canciani, Kalev +Lember, Maarten Bosman, Marcus Meissner, Nis Martensen and Uli Schlachter +have squashed many more bugs and improved the documentation.

A new cairo release! +We are pleased to annouce a new stable release of Cairo that brings many +new features and performance improvements, all whilst maintaining +compatibility with cairo-1.0 and all releases since. We recommend anyone +using a previous release of Cairo to upgrade to 1.12.0. + +The major feature of this release is the introduction of a new procedural +pattern; the mesh gradient. This, albeit complex, gradient is constructed +from a set of cubic Bezier patches and is a superset of all other gradient +surfaces which allows for the construction of incredibily detailed patterns. +In PDF parlance, the mesh gradient corresponds with type 7 patterns. Many +thanks to Andrea Canciani for bringing this to Cairo, and for his work on +making gradient handling robust. + +Not content with just adding another procedural pattern, Cairo 1.12 also +adds new API to create a callback pattern, +cairo_pattern_create_raster_source, that allows the application to +provide the pixel data for the region of interest at the time of +rendering. This can be used for instance, by an application to decode +compressed images on demand and to keep a cache of those decompressed +images, independently of Cairo. When combined with the recording +surface, it should form a useful basis for a deferred renderer. + +With the release of cairo-1.12, we also introduce a new supported +backend for interoperating with X using XCB. Uli Schlachter, also +maintainer of awesome and contributor to libxcb, has volunteered to +maintain cairo-xcb for us. Thanks Uli! + +For cairo-1.12, we have also added some common API to address any +surface as an image and so allow direct modification of the raster data. +Previously, only the Quartz and Win32 backends supported a very narrow +interface to allow for efficient pixel upload. Now with +cairo_surface_create_similar_image, cairo_surface_map_to_image, and +cairo_surface_unmap_image, Cairo exports a consistent method for +treating those surfaces as an image and so allow modification inplace. +These are the same routines used internally, and should support +efficient transfer or direct mapping of the target surfaces as +applicable. + +Another focus over the past year has been to address many performance +issues, without sacrificing the composition model. To accomplish the +goal, once again the rasterisation pipeline was overhauled and made +explicit, giving the backends the freedom to implement their own +specific pipeline whilst also providing a library of common routines +from which to build the pipeline. For instance, this allows the image +backend and the gl backend to composite scan line primitives inplace, +and to then implement custom fallbacks to catch the corner cases that do +not map onto their fastest paths. Similarly, this allows for the Xlib +backend to implement trapezoidation without compromising the other +backends, yet still allow for the pipeline to be used elsewhere for +testing and fallbacks. Clipping was once again overhauled, so that the +common cases for the raster pipelines could be captured and processed +with fast paths with the emphasis on performing geometric clipping to +reduce the frequency of using multi-pass clipmasks. Stroking was made +faster, both by providing specialised fast-paths for simple, yet frequent, +cases (such as stroking around a rectangle) and by reducing the number +of edges generated by the general stroker. + +As part of the focus on performance, Cairo 1.12 introduces some +antialias hints (NONE, FAST, GOOD, BEST) that are interpolated by the +rasterisers to fine tune their performance versus quality. Cairo 1.12 +also introduces a new observation architecture, +cairo_surface_observer_t, which can be used to analyse the amount of +time consumed by drawing commands and help identify inefficiencies in +both Cairo and the application. + +Last, but by no means least, the OpenGL backend has seen significant +work including the port to GLESv2 and the exploitation of advanced +hardware features. Interesting times. + +As always, I would like to thank everyone who contributed to Cairo, +not only through writing code, but also submitting documentation, bug +reports, suggestions and generally having fun with Cairo! In particular +though this release could not have happened without the efforts of +Adrian Johnson, Alexandros Frantiz, Andrea Canicani, Martin Robinson, +Nis Martensen, and Uli Schlachter. Thanks. +-Chris + +Snapshot 1.11.4 (2012-13-12) +============================ +The cairo community is pleased to finally announce the long aniticpated +release candidate for 1.12, 1.11.4, of the cairo graphics library. This +is the first major update to cairo in over a year and brings a large +number of new features; undoubtably a few bugs as well. + +While many people have contributed and have helped to test the release, +providing feedback on 1.10 and suggesting improvements, this release +is the result of a few persevering souls who deserve recognition for their +outstanding contributions: Andrea Canciani (all round bug fixing, +performance tuning and master of the gradients), Adrian Johnson (PDF +supremo) and Uli Schlachter (who stepped forward as maintainer for the +XCB backend). + +Major additions since 1.11.2: + + * cairo_surface_map_to_image API for pixel level access to any surface + + * New antialias hints to control the trade-off between speed and quality + + * A callback pattern, cairo_pattern_create_raster_source, for lazy + decoding of image data. + + * cairo_surface_observer_t, a new type of surface to gather performance + statistics + + * XCB as a supported backend + + * A rewritten compositor pipeline for performance improvements for, but not + limited to, the xlib and image backends. + From ION and PineView through to SandyBridge, every machine I have shows + across the board performance improvement on the cairo-traces: + + i5-2520m gnome-system-monitor: 5.97x speedup + pnv gnome-system-monitor: 4.86x speedup + i5-2520m firefox-asteroids: 4.66x speedup + pnv firefox-asteroids: 4.43x speedup + image firefox-canvas: 3.82x speedup + i5-2520m firefox-canvas-alpha: 3.49x speedup + image firefox-asteroids: 2.87x speedup + pnv firefox-talos-svg: 2.83x speedup + ion grads-heat-map: 2.75x speedup + pnv firefox-canvas-alpha: 2.66x speedup + image gnome-system-monitor: 2.66x speedup + image swfdec-giant-steps: 2.46x speedup + image firefox-canvas-alpha: 2.14x speedup + i5-2520m firefox-talos-svg: 2.03x speedup + image grads-heat-map: 2.02x speedup + ion gnome-system-monitor: 2.00x speedup + pnv firefox-particles: 1.99x speedup + i5-2520m grads-heat-map: 1.96x speedup + pnv firefox-canvas: 1.92x speedup + ion firefox-particles: 1.80x speedup + image poppler-reseau: 1.77x speedup + pnv xfce4-terminal-a1: 1.72x speedup + image firefox-talos-svg: 1.65x speedup + pnv grads-heat-map: 1.63x speedup + i5-2520m firefox-canvas: 1.63x speedup + pnv swfdec-youtube: 1.62x speedup + image ocitysmap: 1.59x speedup + i5-2520m firefox-fishbowl: 1.56x speedup + i5-2520m poppler-reseau: 1.50x speedup + i5-2520m evolution: 1.50x speedup + i5-2520m midori-zoomed: 1.43x speedup + pnv firefox-planet-gnome: 1.42x speedup + i5-2520m firefox-talos-gfx: 1.41x speedup + i5-2520m gvim: 1.41x speedup + pnv ocitysmap: 1.37x speedup + image poppler: 1.31x speedup + ion firefox-canvas-alpha: 1.35x speedup + ion firefox-talos-svg: 1.34x speedup + i5-2520m ocitysmap: 1.32x speedup + pnv poppler-reseau: 1.31x speedup + i5-2520m firefox-planet-gnome: 1.31x speedup + pnv firefox-fishbowl: 1.30x speedup + pnv evolution: 1.28x speedup + image gvim: 1.27x speedup + i5-2520m swfdec-youtube: 1.25x speedup + pnv gnome-terminal-vim: 1.27x speedup + pnv gvim: 1.25x speedup + image firefox-planet-gnome: 1.25x speedup + image swfdec-youtube: 1.25x speedup + ... + +And a plethora of minor improvements everywhere! +-Chris + +Snapshot 1.11.2 (2011-01-23) +=========================== + +In this first snapshot along the way to cairo-1.12.0, we are very excited +to announce the introduction of Bezier surface gradients, known as type +6/7 gradients in PS/PDF parlance. This is the culmination of much work by +the dynamic duo: Adrian Johnson and Andrea Canciani. Thanks guys! + +Also, I want to warmly welcome Uli Schlachter who recently joined the +Cairo community on a mission. That mission is to make cairo-xcb a +supported backend for 1.12. And for this snapshot he has made great +strides in fixing all the bugs I had left behind. Thanks Uli! + +And we have also seen a new contributor, Alexandros Frantzis, who has +begun bringing up cairo-gl for GLESv2 devices. Thanks Alex! + +And lastly, I must also thank Adrian and Andrea for the vast numbers of +bugs that they have tackled between them, fixing all those little corner +cases that lie hidden until too late. + +API additions: + +The ability to construct piece-wise Bezier surface gradients: + + cairo_pattern_create_mesh + + constructs a pattern of type CAIRO_PATTERN_TYPE_MESH using + + cairo_pattern_mesh_begin_patch + cairo_pattern_mesh_end_patch + cairo_pattern_mesh_curve_to + cairo_pattern_mesh_line_to + cairo_pattern_mesh_move_to + cairo_pattern_mesh_set_control_point + cairo_pattern_mesh_set_corner_color_rgb + cairo_pattern_mesh_set_corner_color_rgba + cairo_pattern_mesh_get_patch_count + cairo_pattern_mesh_get_path + cairo_pattern_mesh_get_corner_color_rgba + cairo_pattern_mesh_get_control_point + +The introduction of a unique ID accessible via the mime data type: + CAIRO_MIME_TYPE_UNIQUE_ID + + + + + +Release 1.10.2 (2010-12-25 Chris Wilson <chris@chris-wilson.co.uk>) +=================================================================== +The cairo community is pleased to announce the 1.10.2 release of the +cairo graphics library. This is the first update to cairo's stable 1.10 +series and contains a large number of bug fixes. + +While many people have contributed and have help to test the release, +2 people deserve special recognition for their efforts in tracking down +and fixing bugs, Andrea Canciani and Adrian Johnson.

This is a major update +to cairo, with new features and enhanced functionality which maintains +compatibility for applications written using any previous major cairo +release, (1.8, 1.6, 1.4, 1.2, or 1.0). We recommend that anybody using +a previous version of cairo upgrade to cairo 1.10.0. + +One of the more interesting departures for cairo for this release is the +inclusion of a tracing utility, cairo-trace. cairo-trace generates a +human-readable, replayable, compact representation of the sequences of +drawing commands made by an application. This can be used to inspecting +applications to understand issues and as a means for profiling +real-world usage of cairo. + +The traces generated by cairo-trace have been collected in + + git://git.cairographics.org/git/cairo-traces + +and have driven the performance tuning of cairo over the last couple of +years. In particular, the image backend is much faster with a new +polygon rasterisation and a complete overhaul of the tessellator. Not +only is this faster, but also eliminates visual artifacts from +self-intersecting strokes. Not only has cairo-trace been driving +performance improvements within cairo, but as a repeatable means of +driving complex graphics it has been used to tune OpenGL, DDX, and +pixman. + +Cairo's API has been extended to better support printing, notably +through the ability to include a single compressed representation of an +image for patterns used throughout a document, leading to dramatic file +size reductions. Also the meta-surface used to record the vector +commands compromising a drawing sequence is now exposed as a +CAIRO_SURFACE_TYPE_RECORDING, along with a new surface that is a child of a +larger surface, CAIRO_SURFACE_TYPE_SUBSURFACE. One typical usage of a +subsurface would be as a source glyph in a texture atlas, or as a +restricted subwindow within a canvas. + +Cairo's API has also resurrected the RGB16 format from the past as +the prevalence of 16-bit framebuffers has not diminished and is a +fore-taste of the extended format support we anticipate in the future. +Increasing cairo's utility, we introduce the cairo_region_t for handling +sets of pixel aligned rectangles commonly used in graphics applications. +This is a merger of the GdkRegion and the pixman_region_t, hopefully +providing the utility of the former with the speed of the latter. + +Furthermore cairo has been reworked to interoperate more closely with +various acceleration architectures, gaining the ability to share +those hardware resources through the new cairo_device_t. For instance, +with the new OpenGL backend that supersedes the Glitz backend, hardware +and rendering operations can be shared between a classic OpenGL +application mixing libVA for the hardware assisted video decode with +cairo for high quality overlays all within the same OpenGL canvas. + +Many thanks for the hard work of Adrian Johnson, Andrea Canciani, Behdad +Esfahbod, Benjamin Otte, Carl Worth, Carlos Garcia Campos, Chris Wilson, +Eric Anholt, Jeff Muizelaar, Karl Tomlinson, M Joonas Pihlaja, Søren +Sandmann Pedersen and many others that have contributed over the last +couple of years to cairo. Thank you all! + +Snapshot 1.9.14 (2010-07-26) +============================ + + A quiet couple of weeks, hopefully Cairo is seeing widescale deployment and + we are being to see the results of the stabilisation effort. Clipping bugs + seems to have been the order of the last couple of weeks, with a couple + reported and duly fixed. Thank you Igor Nikitin and Karl Tomlinsion for + finding those regressions.

The chief bug fixer has been Benjamin Otte who not only + made sure that the public API is consistent and being tested for its + consistency, but also ensured that the documentation was up-to-date and + spent time clarifying cases where even the Cairo developers have come + unstuck in the past. Many thanks, Benjamin. However, he was not alone, + as Andrea Canciani continued his fine work in isolating broken corner cases + and proceeding to fix them, and tidying up the quartz backend. And last, but + definitely not least, M Joonas Pihlaja tried building Cairo across a + perverse range of systems and fixed up all the loose bits of code that came + unravelled. Thanks everybody! + +API Changes +----------- + + cairo_surface_set_mime_data, cairo_surface_get_mime_data: + + The length parameter is now an unsigned long (as opposed to an unsigned + int). The parameter is intended to be an equivalent to a size_t without + requiring POSIX types and be large enough to store the size of the + largest possible allocation. + + cairo_gl_surface_create_for_texture: + + This a new surface constructor for cairo-gl that explicitly enables + render-to-texture for foreign, i.e. application, textures. + + cairo_region_xor, cairo_region_xor_rectangle + + A couple of utility routines add to the region handling interface for + the purpose of replacing existing GdkRegion functionality. + +Bugs fixes +---------- + + https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/600622 + + Inkscape was caught in the act of attempting to modify a finished surface. + Unfortunately, we had the ordering of our guards and assertions wrong and + so an ordinary application error was triggering an assert in Cairo. This + lead Benjamin to add a test case to ensure that the entire public API + could handle erroneous input and then proceeded to fix a whole slew of + uncovered bugs. + + + https://bugs.freedesktop.org/show_bug.cgi?id=28888 + + A regression introduced by the special casing of uploading images to an + xlib surface in-place which was ignoring the translation applied to the + image. + + +Snapshot 1.9.10 (2010-06-26) +============================ + + The first "quick" snapshot in the run up to the stable release. The + last snapshot was picked up by the bleeding edge distributions and so the + bug reports have to started to roll in. The most frequent of these are the + introduction of rendering errors by applications that modify a surface + without subsequently calling cairo_surface_mark_dirty(). Make sure the + application developers are aware of increased reliance on strict use of the + Cairo API before 1.10 is released! + + The usual slew of bugs reported and we would like to thank Zoxc for + contributing the WGL interface for cairo-gl, and finding more build + failures on win32. And it just wouldn't be a 1.9 snapshot unless + Benjamin Otte improved the error handling within cairo-gl, as well as + isolating and fixing some more errors in the test suite. The biggest bug of + the snapshot turned out to be a major sign extension issue that had lain + hidden for many years and was suddenly exposed by incorrectly rounding + rectangles when performing non-antialiased rendering. Also to the relief + of many we have included the downstream patch to honour the user's LCD + filtering preferences for subpixel rendering of fonts. The interface + remains private for the time being, whilst the proposed public API is + finalized. + +API changes +----------- + None. + +Snapshot 1.9.8 (2010-06-12) +=========================== + + One major API changes since the last snapshot, and a whole slew of bugs + fixed and inconsistencies eliminated. Far too many bugs fixed to + individually identify. We need to thank Benjamin Otte for his fantastic + work on the cairo-gl backend making it faster and more robust, Andrea + Canciani for finding so many bugs and developing test cases for them, as + well fixing them. And last but not least we must all thank Adrian Johnson for + continuing to eliminate bugs and improving the PostScript and PDF backends. + + This snapshot represents almost 4 months of bug fixing, bringing Cairo to + a point where we consider it almost ready to be a candidate for release. + There are a few known bugs left to be fixed, being tracked in + https://bugs.freedesktop.org/show_bug.cgi?id=24384, so please give Cairo a + whirl and report any regressions. The plan is to release a new snapshot + every other week leading to a 1.10 release with a target date of + 2010-08-16. + +API additions +------------- + CAIRO_FORMAT_RGB16_565 + + 16 bit devices still remain popular, and so with great demand, + CAIRO_FORMAT_RGB16_565 has been restored enabling applications to create + and use 16 bit images as sources and render targets. + + cairo_surface_create_for_rectangle() + + It is common practice to cut an image up into many smaller pieces and use + each of those as a source - a technique called texture atlasing. + cairo_surface_create_for_rectangle() extends Cairo to directly support use + of these subregions of another cairo_surface_t both as a source and as a + render target. + + cairo_region_create() + cairo_region_create_rectangle() + cairo_region_create_rectangles() + cairo_region_copy() + cairo_region_reference() + cairo_region_destroy() + cairo_region_equal() + cairo_region_status() + cairo_region_get_extents() + cairo_region_num_rectangles() + cairo_region_get_rectangle() + cairo_region_is_empty() + cairo_region_contains_rectangle() + cairo_region_contains_point() + cairo_region_translate() + cairo_region_subtract() + cairo_region_subtract_rectangle() + cairo_region_intersect() + cairo_region_intersect_rectangle() + cairo_region_union() + cairo_region_union_rectangle() + + The Cairo region API was actually added a couple of snapshots ago, but we + forgot to mention it at the time. A simple API for the handling of + rectangular pixel-aligned regions by Soeren Sandmann. + + +Backend-specific improvements +----------------------------- +cairo-gl + + Benjamin Otte made more than 200 commits in which he refactored the cairo-gl + backend, reducing a lot of code duplication and enabled him to begin working + on improving performance by reducing state changes and associated overhead. + +cairo-xlib + + Access to the underlying connection to the Display is now thread-safe + enabling cairo-xlib to be used in a multi-threaded application without fear + of random corruption. Thanks Benjamin Otte! + + cairo-xlib will now attempt to use PolyModeImprecise when compositing + trapezoids (i.e. a fill or a stroke operation with a non-trivial path) which + should allow hardware drivers more scope for accelerating the operation at + the cost of potentially incurring minute rendering errors. The mode can be + forced back to PolyModePrecise by setting the antialias parameter to + CAIRO_ANTIALIAS_SUBPIXEL. + +cairo-svg + + A notable improvement was contributed by Alexander Shulgin to enable SVG to + reference external image through the use an extended MIME data type. + +Snapshot 1.9.6 (2010-02-19) +=========================== +API additions +------------- + Add cairo_device_t + + The device is a generic method for accessing the underlying interface + with the native graphics subsystem, typically the X connection or + perhaps the GL context. By exposing a cairo_device_t on a surface and + its various methods we enable finer control over interoperability with + external interactions of the device by applications. The use case in + mind is, for example, a multi-threaded gstreamer which needs to serialise + its own direct access to the device along with Cairo's across many + threads. + + Secondly, the cairo_device_t is a unifying API for the mismash of + backend specific methods for controlling creation of surfaces with + explicit devices and a convenient hook for debugging and introspection. + + The principal components of the API are the memory management of: + + cairo_device_reference(), + cairo_device_finish() and + cairo_device_destroy(); + + along with a pair of routines for serialising interaction: + + cairo_device_acquire() and + cairo_device_release() + + and a method to flush any outstanding accesses: + + cairo_device_flush(). + + The device for a particular surface may be retrieved using: + + cairo_surface_get_device(). + + The device returned is owned by the surface. + +API changes (to API new in the cairo 1.9.x series) +-------------------------------------------------- + cairo_recording_surface_create() + cairo_recording_surface_ink_extents() + + These are the replacement names for the functions previously named + cairo_meta_surface_create and cairo_meta_surface_ink_extents. + + cairo_surface_set_mime_data + + This interface is now changed such that the MIME data will be + detached if the surface is modified at all. This guarantees that + the MIME data will not become out of synch due to surface + modifications, and also means that for the MIME data to be useful, + it must be set after all modifications to the surface are + complete. + +API removal (of experiment API) +------------------------------- + The cairo-glitz backend is removed entirely, (in favor of the new + cairo-gl backend). See below for more on cairo-gl. + +Generic fixes +------------- + + Many improvements for drawing of dashed strokes + + Fix incorrect handling of negative offset + Faster computation of first dash (avoids near-infinite looping) + Approximate extremely fine dash patterns with appropriate alpha value + + Optimize spans-based renderers for repeated rows, (such as in a rounded rectangle) + +Backend-specific improvements +----------------------------- +cairo-drm + + This is a new, direct-rendering backend that supports Intel graphics + chipsets in the i915 and i965 families. It's still experimental and + will likely remain that way for a while. It's already got extremely + good performance on the hardware it supports, so if nothing else + provides a working proof and performance target for the cairo-gl + work for Intel graphics. + +cairo-gl + + Start using GLSL to accelerate many operations. Many thanks to Eric + Anholt and T. Zachary Laine for this work. For the first time, we + have what looks like what will be a very compelling OpenGL-based + backend for cairo (in terms of both quality and performance). + + See this writeup from Eric for more details on recent progress of + cairo-gl (which he presented at FOSDEM 2010): + + http://anholt.livejournal.com/42146.html + +cairo-image + + The image backend is made dramatically faster (3-5 times faster for + benchmarks consisting primarily of glyph rendering). + +cairo-quartz fixes: + + Many fixes from Robert O'Callahan and Andrea Canciani including: + + Fixed gradient pattern painting + Improved A8 image handling + Fixes for "unbounded" and other compositing operators + +cairo-pdf fixes: + + Improvements to embedding of JPEG and JPEG2000 data. + +cairo-ps fixes: + + Fix printing of rotated user fonts. + +Snapshot 1.9.4 (2009-10-15) +=========================== +API additions: + + cairo_meta_surface_create() + cairo_meta_surface_ink_extents() + + Finally exporting the internal meta-surface so that applications + have a method to record and replay a sequence of drawing commands. + + cairo_in_clip() + + Determines whether a given point is inside the current clip. + ??? Should this be called cairo_in_paint() instead? in-clip is the test + that is performed, but in-paint would be similar to in-fill and in-stroke. + +New utilities: + + cairo-test-trace + + A companion to cairo-perf-trace, this utility replays a trace against + multiple targets in parallel and looks for differences in the output, + and then records any drawing commands that cause a failure. + Future plans: + Further minimisation of the fail trace using "delta debugging". + More control over test/reference targets. + +Backend improvements: + + xlib + + Server-side gradients. The theory is that we can offload computation + of gradients to the GPU and avoid pushing large images over the + connection. Even if the driver has to fallback and use pixman to render + a temporary source, it should be able to do so in a more efficient manner + than Cairo itself. However, cairo-perf suggests otherwise: + + On tiny, Celeron/i915: + + before: firefox-20090601 211.585 + after: firefox-20090601 270.939 + + and on tiger, CoreDuo/nvidia: + + before: firefox-20090601 70.143 + after: firefox-20090601 87.326 + + In particular, looking at tiny: + + xlib-rgba paint-with-alpha_linear-rgba_over-512 47.11 (47.16 0.05%) -> 123.42 (123.72 0.13%): 2.62x slowdown + █▋ + xlib-rgba paint-with-alpha_linear3-rgba_over-512 47.27 (47.32 0.04%) -> 123.78 (124.04 0.13%): 2.62x slowdown + █▋ + + +New experimental backends: + + QT + + OpenVG - The initial work was done by Øyvind Kolås, and made ready for + inclusion by Pierre Tardy. + + OpenGL - An advanced OpenGL compositor. The aim is to write a integrate + directed rendering using OpenGL at a high-level into Cairo. In + contrast to the previous attempt using Glitz which tried to + implement the RENDER protocol on top of OpenGL, using the + high-level interface should permit greater flexibility and + more offloading onto the GPU. + The initial work on the backend was performed by Eric Anholt. + +Long standing bugs fixed: + + Self-intersecting strokes. + + A long standing bug where the coverage from overlapping semi-opaque + strokes (including neighbouring edges) was simply summed in lieu of + a costly global calculation has been fixed (by performing the costly + global calculation!) In order to mitigate the extra cost, the + tessellator has been overhauled and tune, which handles the fallback + for when we are unable to use the new span rasteriser on the stroke + (e.g. when using the current RENDER protocol). The large number of + pixel artefacts that implementing self-intersection elimination + removes is ample justification for the potential performance + regression.

This is the first update to cairo's stable 1.8 +series and contains a large number of bug fixes. It is being released +just over one month since cairo 1.8.0. + +This release consists primarily of bug fixes, but there is one notable +new feature, (the ability to build cairo without an external font +backend), and there are a few optimizations as well. See below for +details on these changes and the most important bug fixes. + +While many people have contributed to this release, Chris Wilson +deserves particular mention. He has contributed well over twice as +many changes to cairo since 1.8.0 than everyone else combined. We +greatly appreciate the tremendous efforts of Chris and all cairo +contributors. + +We recommend everyone upgrade to cairo 1.8.2 and hope that everyone +will have lots of fun with cairo! + +-Carl + +New feature +----------- +It is now possible to build cairo without any font backend, (such as +freetype, win32 or quartz). This is most useful when the application +provides custom font rendering through the user-font API. But in the +case where no external font backend is available, and no user-font is +provided, cairo will render with a failsafe font, (a stroked font +covering visible ASCII character). (Behdad Esfahbod) + +Optimizations +------------- +Dramatically speed up compilation with dolt (removes much of the +libtool overhead) (Behdad Esfahbod with thanks to Josh Triplett). + +Several minor optimizations to tessellator (special-cased comparisons, +faster insert for skiplist, etc.) (Chris Wilson). + +Optimize away fractional translation component when doing +EXTEND_NEAREST filtering, (for better performance). + +General bug fixes +----------------- +Allow cloning sub-regions of similar surfaces to fix this bug +(Chris Wilson): + + Crafted gif file will crash firefox + [XError: 'BadAlloc (insufficient resources for operation)'] + https://bugzilla.mozilla.org/show_bug.cgi?id=424333 + +Fix some matrix confusion to fix this regression (Chris Wilson): + + Translucent star exports in a wrong way to PDF + https://bugs.launchpad.net/inkscape/+bug/234546 + +Fix some long-standing bugs with respect to properly computing the +extents of transformed, filtered surfaces (Owen Taylor, Carl Worth, +and Chris Wilson): + + Bad clipping with EXTEND_NONE + http://bugs.freedesktop.org/show_bug.cgi?id=15349 + + Improve filtering handling in cairo-pattern.c + http://bugs.freedesktop.org/show_bug.cgi?id=15367 + + Many thanks to Chris Wilson for digging out and cleaning up + these fixes. + +Fix compilation on Solaris 10 (Chris Wilson): + + Cairo requires -DREENTRANT (along with -D_POSIX_THREAD_SEMANTICS) + to compile on Solaris 10 with pthreads + https://bugs.freedesktop.org/show_bug.cgi?id=18010 + +Fix very old bug causing dashes to be rendered at the wrong length in +fallback images (Adrian Johnson) + + Dashed strokes too long in fallback images + https://bugs.freedesktop.org/show_bug.cgi?id=9189 + +Fix broken dashing when a dashed path starts outside the clip region +(Chris Wilson). + +Avoid range overflow when computing large patterns (Benjamin Otte and +Chris Wilson). + +Avoid crashing due to an invalid font with an incorrect entry in its +CMAP table (Adrian Johnson). + +Fix bugs in computing maximum size of text requests that can be sent +with the Render extension, (avoiding potential crashes when rendering +large amounts of text) (Behdad Esfahbod and Chris Wilson). + +Fix rendering of operators unbounded by the mask (Chris Wilson). + +Fix compilation on systems without compiler support for a native +64-bit type (Chris Wilson). + +Fix several cases of missing error-status propagation.

This requires the user to set a CAIRO_WIN32_STATIC_BUILD +environment variable when compiling (Behdad Esfahbod). + +Release 1.8.0 (2008-09-25 Carl Worth <cworth@cworth.org>) +========================================================= +The cairo community is happy (and relieved) to announce the 1.8.0 +release of the cairo graphics library. This is a major update to +cairo, with new features and enhanced functionality which maintains +compatibility for applications written using any previous major cairo +release, (1.6, 1.4, 1.2, or 1.0). We recommend that anybody using a +previous version of cairo upgrade to cairo 1.8.0. + +The dominant theme of this release is improvements to cairo's ability +to handle text. The highlights include a new "user fonts" feature as +well as a new cairo_show_text_glyphs API which allows glyphs to be +embedded in PDF output along with their original text, (for searching, +selection, and copy-and-paste). Another major feature is a revamp of +cairo's build system making it much easier to build cairo on various +platforms. + +See below for more details. + +User fonts +---------- +This new API allows the user of cairo API to provide drawings for +glyphs in a font. A common use for this is implementing fonts in +non-standard formats, like SVG fonts and Flash fonts. This API can +also be used by applications to provide custom glyph shapes for fonts +while still getting access to cairo's glyph caches. See +test/user-font.c and test/user-font-proxy.c for usage examples. This +is based on early work by Kristian Høgsberg. Thanks Kristian! + +This new API consists of the following functions (and corresponding +_get functions): + + cairo_user_font_face_create + + cairo_user_font_face_set_init_func + cairo_user_font_face_set_render_glyph_func + cairo_user_font_face_set_text_to_glyphs_func + cairo_user_font_face_set_unicode_to_glyph_func + +An additional, new API is + + cairo_scaled_font_text_to_glyphs + +We were previously reluctant to provide this function as +text-to-glyphs support in cairo was limited to "toy" font +functionality, not really interesting for real-world text +processing. However, with user fonts landing, this API is needed to +expose full access to how user fonts convert text to glyphs. This is +expected to be used by text toolkits like Pango, as well as "proxy" +user-font implementations. + +cairo_show_text_glyphs +---------------------- +This new API allows the caller of cairo to provide text data +corresponding to glyphs being drawn. The PDF backend implements this +new API so that complex text can be copied out of cairo's PDF output +correctly and reliably, (assuming the user of cairo calls +cairo_show_text_glyphs). The cairo_show_text_glyphs API is definitely +the most daunting API to debut in cairo. It is anticipated that pango +(and similar high-level text libraries) will be the primary users of +this API. In fact, pango 1.22 already uses cairo_show_text_glyphs. +Behdad was the architect and implementor of this effort. Thanks, +Behdad! + +The cairo_show_text_glyphs API includes the following new functions: + + cairo_show_text_glyphs + + cairo_glyph_allocate + cairo_glyph_free + + cairo_text_cluster_allocate + cairo_text_cluster_free + + cairo_surface_has_show_text_glyphs + +Build system revamp +------------------- +The primary goal of the revamp is to make the build system less +fragile, (particularly for non-Linux platforms). For example, now +people building on win32 will no longer need to maintain a +platform-specific list of files to be built. See the new README.win32 +for details. Also, the .so file will now be installed with a different +naming scheme, (for example, 1.7.6 will install with a .10800 +suffix). Many thanks to Behdad and his small army of helpers! + +Assorted API additions +---------------------- +For API completeness, several missing "getter" functions were added: + + cairo_scaled_font_get_scale_matrix + + cairo_surface_get_fallback_resolution + + cairo_toy_font_face_create + cairo_toy_font_face_get_family + cairo_toy_font_face_get_slant + cairo_toy_font_face_get_weight + +The new cairo_toy_font_face functions provide access to functionality +and settings provided by cairo_select_font_face(). Thanks Behdad! + +cairo-ps/cairo-pdf: More efficient output +----------------------------------------- +Adrian Johnson has been busy fixing all kinds of bugs in PS and PDF +backends, as well making them generate much more compact output by +avoiding things like re-emitting the color or linestyle on every +drawing operation. Thanks Adrian! + +cairo-xlib: dithering +--------------------- +Dithering: Cairo now does simple dithering when rendering to legacy X +servers. This is most visible with 8-bit visuals. Thanks Behdad! + +cairo-xlib: Avoid rendering glyphs out of surface bounds +-------------------------------------------------------- +This seemingly harmless optimization exposed a bug in OpenOffice.org 3 +versions where OO.o was passing bogus surface extents to cairo, +resulting in no text rendered in OO.o. Please contact your +distribution's OO.o maintainers if you see this bug and point them to +the following URL: + + https://bugs.freedesktop.org/show_bug.cgi?id=16209 + +cairo-xlib: Improved performance with X server without Render +------------------------------------------------------------- +Cairo now performs better on remote X servers that lack the Render +extension by being smarter about using X core protocol facilities +instead of falling back to doing all rendering on the client side. + +cairo-ft: respecting FC_FT_FACE +------------------------------- +Previously it was impossible to instruct cairo to do emboldening on a +font face object created from an FT_Face. Cairo now respects and uses +the FC_FT_FACE fontconfig pattern element, so emboldening can be +achieved by using cairo_ft_font_face_create_for_pattern() and a +carefully crafted pattern using FC_FT_FACE and FC_EMBOLDEN. Thanks +Behdad! + +cairo-directfb: backend improvements +------------------------------------ +The directfb backend, though still unsupported, has seen a good deal +of improvements.

Thanks Chris and others! + +Note also that the code that had been in cairo 1.7.x calling into +freetype's optional lcd_filter function was removed from cairo before +the 1.8.0 release. We do expect this code to come back in some form in +the future. + +Snapshot 1.7.6 (2008-09-17 Carl Worth <cworth@cworth.org>) +========================================================== +The cairo community is happy to announce the 1.7.6 snapshot of the +cairo graphics library. This is a "release candidate" for the upcoming +1.8.0 release, so we will greatly appreciate any reports of problems +in this release, and no major changes are currently planned before +1.8. + +Notable changes in 1.7.6 +------------------------ +The largest number of changes since 1.7.4 did not change the +implementation of cairo itself, but instead revamped cairo's build +system. The primary goal of the revamp is to make the build system +less fragile, (particularly for non-Linux platforms). For example, now +people building on win32 will no longer need to maintain a +platform-specific list of files to be built. Also, the .so file will +now be installed with a different naming scheme, (for example, 1.7.6 +will install with a .10706 suffix). Much thanks, Behdad! + +And, as usual, Chris Wilson has made another large round of robustness +improvements, (eliminating dead code, fixing propagation of error +status values, test suite improvements, etc. etc.). Thanks as always, +Chris! + +API changes since 1.7.4 +----------------------- +There have been a few changes of API that was new during the 1.7 +series: + +* Remove cairo_font_options_set_lcd_filter + and cairo_font_options_get_lcd_filter + + Motivation: At the Cairo Summit, this API was determined to be too + specific to the freetype font backend to be in the general + API. A similar API with a cairo_ft prefix might be introduced + in the future. Note that cairo will still respect the + corresponding fontconfig settings for these options. + +* Replace cairo_has_show_glyphs + with cairo_surface_has_show_glyphs + + Motivation: This really is a surface-specific interface, and the + convenience function on the cairo_t is not obviously + necessary. An application can easily call: + + cairo_surface_has_show_glyphs (cairo_get_target (cr)); + + as needed. + +* Add cairo_text_cluster_flags_t + to cairo_show_text_glyphs + cairo_scaled_font_text_to_glyphs + cairo_user_scaled_font_text_to_glyphs_func_t + + Motivation: This flag, (and specifically the + CAIRO_TEXT_CLUSTER_FLAG_BACKWARD value), replaces the + cairo_bool_t backward argument in each of the above + interfaces. This leads to more readable user code, and also + allows future extensibility. + +As always, there are no changes to any API from any major cairo +release, (1.0.x, 1.2.x, 1.4.x, 1.6.x). Cairo maintains the same +compatibility promise it always has. + +Bug fixes since 1.7.4 +--------------------- +xlib: Faster bookkeeping (Karl Tomlinson) + https://bugzilla.mozilla.org/show_bug.cgi?id=453199#c5 + +PS: Fix gradients with non-constant alpha (Chris Wilson) + +Fix deadlock in user-font code (Richard Hughes and Behdad Esfahbod) + http://bugs.freedesktop.org/show_bug.cgi?id=16819 + +Several other minor fixes. + +Snapshot 1.7.4 (2008-08-11 Behdad Esfahbod <behdad@behdad.org>) +=============================================================== +The cairo community is embarrassed to announce availability of the 1.7.4 +snapshot of the cairo graphics library. This is a followup release to the +1.7.2 snapshot to ship a tarball that can actually be built. The only +change since 1.7.4 is including the missing header file +cairo-user-font-private.h in the distribution. + +Snapshot 1.7.2 (2008-08-11 Behdad Esfahbod <behdad@behdad.org>) +=============================================================== +The cairo community is finally ready to announce availability of the 1.7.2 +snapshot of the cairo graphics library. This is embarrassingly the first +snapshot in the 1.7 unstable series of cairo, leading to the eventual release +of cairo 1.8, currently planned for late September. + +This snapshot comes four months after the 1.6.4 release. We have done a +really bad job on getting development snapshots out this cycle, but +hopefully all the API changes for 1.8 are now finished and the remaining +weeks will be spent on bug-fixing. There is more than 400 commits worth +of changes in this snapshot, and those can use some testing. Read on! + +Text, text, and more text! +-------------------------- +The dominant theme of this release, and 1.8 in general, is improvements +around cairo text API. Here is a high-level list of changes with text +handling: + +User fonts +---------- +This is new API allowing the user of cairo API to provide drawings for glyphs +in a font. This is most useful in implementing fonts in non-standard formats, +like SVG fonts and Flash fonts, but can also be used by games and other +applications to draw "funky" fonts. See test/user-font.c and +test/user-font-proxy.c for usage examples. This is based on early work by +Kristian Høgsberg. Thanks Kristian! + +show_text_glyphs +---------------- +This new API allows the caller of cairo to mark text glyphs with their +original text. The PDF backend implements this new API and latest Pango +master uses it. The result is (when bugs are fixed) that complex text can be +copied out of pangocairo's PDF output correctly and reliably. There are bugs +to fix though. A few poppler bugs, and some more in cairo and pango. + +To test show_text_glyph, just grab pango master and this cairo snapshot and +print text in gedit. Open in acroread or evince, select all, copy, paste +in gedit and compare. The Arabic text with diacritic marks is particularly +showing bad. Try with pango/pango-view/HELLO.txt if you are brave +enough. The Indic text is showing improvements, but is still coming out +buggy. + +LCD subpixel filtering using FreeType +------------------------------------- +FreeType 2.3.5 added support for various LCD subpixel filtering, and +fontconfig 2.6.0 added support for configuring LCD filter on a font by font +basis. Cairo now relies on FreeType and fontconfig for subpixel filtering. +This work is based on David Turner's original patch to cairo, maintained +and tested by Sylvain Pasche and others. Thanks all! + +Toy font face constructor and getter +------------------------------------ +Mostly for API completion, but also useful for higher level (like Pango) to +hook into what the user has set using cairo_select_font_face(), making that +toy API a bit more useful. + +FreeType: respecting FC_FT_FACE +------------------------------- +Previously it was impossible to instruct cairo to do emboldening on a font +face object created from an FT_Face. Cairo now respects and uses the +FC_FT_FACE fontconfig pattern element, so emboldening can be achieved by +using cairo_ft_font_face_create_for_pattern() and a carefully crafted pattern +using FC_FT_FACE and FC_EMBOLDEN. + + +PS/PDF: More efficient output +----------------------------- +Adrian Johnson has been busy fixing all kinds of bugs in PS and PDF +backends, as well making them generate much more compact output by avoiding +things like re-emitting the color or linestyle on every drawing operation. +Thanks Adrian! + + +Xlib: Dithering +--------------- +Cairo now does simple dithering when rendering to legacy X servers. This is +mostly visible with 8-bit visuals. + +Xlib: Avoid rendering glyphs out of surface bounds +-------------------------------------------------- +This seemingly harmless change manifested a bug with OpenOffice.org 3 versions +where OO.o was passing bogus surface extents to cairo, resulting in no text +rendered in OO.o. Please contact your distro's OO.o maintainers if you see +this bug and point them to the following URL: + + https://bugs.freedesktop.org/show_bug.cgi?id=16209 + +Xlib: Improved performance with Xrender-less X servers +------------------------------------------------------ +Cairo now performs better on remote, Xrender-less X servers by being smarter +about using X core protocol facilities instead of falling back to doing all +rendering on the client side. + + +Directfb: backend improvements +------------------------------ +The directfb backend, though still unsupported, has seen a good deal of +improvements. Thanks Vlad! + + +Bug fixing and optimizations +---------------------------- +Countless bugs have been fixed and optimizations made, many of them thanks to +Chris Wilson. Thanks Chris! + + +API additions +------------- + +cairo_show_text_glyphs + + This is a new text rendering API. Being a more advanced version of + cairo_show_glyphs(), it is aimed for use by higher-level text toolkits like + Pango, and enables better text extraction from output generated by backends + like PDF and SVG. The PDF backend already implements it, and the upcoming + Pango release will use it. + + To make that API work, a bunch of other additions were made: + +cairo_glyph_allocate +cairo_glyph_free +cairo_text_cluster_t +cairo_text_cluster_allocate +cairo_text_cluster_free +cairo_surface_has_show_text_glyphs + + +cairo_user_font_face_create + + This is the "user" font face constructor, accompanied by a variety of method + signatures, getters, and setters for a callback-based font backend: + +CAIRO_FONT_TYPE_USER +cairo_user_scaled_font_init_func_t +cairo_user_scaled_font_render_glyph_func_t +cairo_user_scaled_font_text_to_glyphs_func_t +cairo_user_scaled_font_unicode_to_glyph_func_t +cairo_user_font_face_set_init_func +cairo_user_font_face_set_render_glyph_func +cairo_user_font_face_set_text_to_glyphs_func +cairo_user_font_face_set_unicode_to_glyph_func +cairo_user_font_face_get_init_func +cairo_user_font_face_get_render_glyph_func +cairo_user_font_face_get_text_to_glyphs_func +cairo_user_font_face_get_unicode_to_glyph_func + + +cairo_scaled_font_text_to_glyphs + + We were previously reluctant to provide this function as text-to-glyphs + support in cairo was limited to "toy" font functionality, not really + interesting for real-world text processing. However, with user-fonts + landing, this API is needed to expose full access to how user-fonts + convert text to glyphs. This is expected to be used by text toolkits like + Pango, as well as "proxy" user-font implementations. + + +cairo_lcd_filter_t +cairo_font_options_set_lcd_filter +cairo_font_options_get_lcd_filter + + These add the possibility to choose between various available LCD subpixel + filters. The available filter values are modeled after what FreeType + provides. + + +cairo_toy_font_face_create +cairo_toy_font_face_get_family +cairo_toy_font_face_get_slant +cairo_toy_font_face_get_weight + + These provide access to functionality and settings provided by + cairo_select_font_face(). + + +cairo_scaled_font_get_scale_matrix +cairo_surface_get_fallback_resolution + + For API completeness. + + +Various new values for cairo_status_t enum + + +Known issues: + +- Type3 fonts generated by cairo's PDF backend may show up in poppler/Evince + in a different color than expected. This is fixed in poppler master branch. + This mostly affects cairo user fonts. The test case test/user-font.c + demonstrates this. + +- User fonts using other fonts in their rendering are currently embedded in + PDF as fallback bitmap glyphs. This will be (hopefully) fixed before 1.8. + The test case test/user-font-proxy.c demonstrates this. + + +Release 1.6.4 (2008-04-11 Carl Worth <cworth@cworth.org>) +========================================================= +The cairo community is wildly embarrassed to announce the 1.6.4 +release of the cairo graphics library. This release reverts the xlib +locking change introduced in 1.6.4, (and the application crashes that +it caused). The community would be glad to sack its current release +manager and is accepting applications for someone who could do the job +with more discipline. + +Revert 'add missing locking in cairo-xlib' +------------------------------------------ +This change was introduced in cairo 1.6.2, but also introduced a bug +which causes many cairo-xlib applications to crash, (with a +segmentation fault inside of XSetClipMask). Instead of attempting +another fix for the broken fix, the change in 1.6.2 has been +reverted. The original bug which the change was addressing has been +present since at least cairo 1.4, so it is not expected that leaving +this bug unfixed will cause any new problems for applications moving +from cairo 1.4 to cairo 1.6. + +At this point, the code of cairo 1.6.4 differs from cairo 1.6.0 only +in the fix for the PostScript-printer crashes. + +Tweak build to avoid linking with g++ +------------------------------------- +Cairo 1.6.4 avoids a quirk in automake that was causing the cairo +library to be linked with g++ and linked against libstdc++ even when +only C source files were compiled for the library. + +Release 1.6.2 (2008-04-11 Carl Worth <cworth@cworth.org>) +========================================================= +The cairo community is pleased (but somewhat sheepish) to announce the +1.6.2 release of the cairo graphics library. This is an update to +yesterday's 1.6.0 release with an important fix to prevent cairo's +PostScript output from crashing some printers. This release also +includes a locking fix for cairo's xlib backend to improve thread +safety. There are no changes beyond these two fixes. + +Fix for PostScript printer crash +-------------------------------- +Adrian Johnson discovered that cairo 1.6.0 was being a bit hard on +PostScript printers, by changing the font matrix very frequently. This +causes some PostScript interpreters to allocate new font objects every +few glyphs, eventually exhausting available resources. The fix +involves leaving translational components of the font matrix as zero, +so that the PostScript interpreter sees an identical font matrix +repeatedly, and can more easily share internal font object resources. + +This fix has been tested to resolve the bugs posted here, (for both +Xerox and Dell printers): + + Printing some PDFs from evince is crashing our Xerox printer + http://bugs.freedesktop.org/show_bug.cgi?id=15348 + + Cairo-generated postscript blocks Dell 5100cn + http://bugs.freedesktop.org/show_bug.cgi?id=15445 + +Add missing locking in cairo-xlib +--------------------------------- +Chris Wilson noticed that cairo 1.6.0 was manipulating an internal +cache of GC object within cairo's Xlib backend without proper +locking. The missing locking could cause failures for multi-threaded +applications. He fixed this in 1.6.2 by adding the missing locks. + +Release 1.6.0 (2008-04-10 Carl Worth <cworth@cworth.org>) +========================================================= +The cairo community is quite pleased to announce the 1.6.0 release of +the cairo graphics library. This is a major update to cairo, with new +features and enhanced functionality which maintains compatibility for +applications written using cairo 1.4, 1.2, or 1.0. We recommend that +anybody using a previous version of cairo upgrade to cairo 1.6.0. + +The most significant new features in this release are dramatically +improved PDF and PostScript[*] output, support for arbitrary X server +visuals (including PseudoColor), a new Quartz backend, and and a new +"win32 printing" backend. See below for more details on these and +other new features. + +New dependency on external pixman library (Thanks, Søren!) +---------------------------------------------------------- +As of cairo 1.6, cairo now depends on the pixman library, for which +the latest release can be obtained alongside cairo: + + http://cairographics.org/releases/pixman-0.10.0.tar.gz + +This library provides all software rendering for cairo, (the +implementation of the image backend as well as any image fallbacks +required for other backends). This is the same code that was +previously included as part of cairo itself, but is now an external +library so that it can be shared by both cairo and by the X server, +(which is where the code originated). + +Improved PDF, PostScript, and SVG output (Thanks, Adrian!) +---------------------------------------------------------- +Users of the cairo-pdf, cairo-ps, and cairo-svg should see a dramatic +improvement from cairo 1.2/1.4 to 1.6. With this release there are now +almost no operations that will result in unnecessary rasterization in +the PDF and PostScript. Rasterized "image fallbacks" are restricted +only to minimal portions of the document where something is being +drawn with cairo that is beyond the native capabilities of the +document, (this is rare for PDF or SVG, but occurs when blending +translucent objects for PostScript). + +This means that the final output will be of higher quality, and will +also be much smaller, and therefore will print more quickly. The +machinery for doing analysis and minimal fallbacks also benefits the +win32-printing surface described below. + +In addition to doing less rasterization, the PostScript and PDF output +also has several other improvements to make the output more efficient +and more compatible with specifications. + +[*] Note: Just before this release, a bug has been reported that the +PostScript output from cairo can crash some printers, (so far the +following models have been reported as problematic Xerox Workcentre +7228 or 7328 and Dell 5100cn). We will implement a workaround as soon +as we can learn exactly what in cairo's output these printers object +to, (and we could use help from users that have access to misbehaving +printers). This bug is being tracked here: + + Printing some PDFs from evince is crashing our Xerox printer + http://bugs.freedesktop.org/show_bug.cgi?id=15348 + +New support for arbitrary X server visuals (Thanks, Keith and Behdad!) +---------------------------------------------------------------------- +As of cairo 1.6, cairo should now work with an arbitrary TrueColor or +8-bit PseudoColor X server visual. Previous versions of cairo did not +support these X servers and refused to draw anything. We're pleased to +announce that this limitation has been lifted and people stuck with +ancient display systems need no longer be stuck with ancient software +just because of cairo. + +New, supported Quartz backend for Mac OS X (Thanks, Brian and Vladimir!) +------------------------------------------------------------------------ +As of cairo 1.6, the cairo-quartz backend is now marked as "supported" +rather than "experimental" as in previous cairo releases. Its API now +has guarantees of API stability into future cairo releases, and its +output quality is comparable to other backends. There have been +significant improvements to cairo-quartz since 1.4. It now uses many +fewer image fallbacks, (meaning better performance), and has greatly +improved text rendering. + +New, "win32 printing" backend (Thanks, Adrian and Vladimir!) +------------------------------------------------------------ +A new win32-printing surface has been added with an interface very +similar to the original win32 surface, (both accept an HDC +parameter). But this new surface should only be called with a printing +DC, and will result in all drawing commands being stored into a +meta-surface and emitted after each page is complete. This allows +cairo to analyze the contents, (as it does with PDF, PostScript, and +SVG backends), and to do minimal image-based fallbacks as +necessary. The analysis keeps things as efficient as possible, while +the presence of fallbacks, (when necessary), ensure the consistent, +high-quality output expected from cairo. + +Robustness fixes (Thanks, Chris!) +--------------------------------- +There has been a tremendous number of improvements to cairo's +robustness. Areas that have been improved include: + + * Proper reporting of errors + + * Responding correctly to invalid input + + * Avoiding integer overflows + + * Avoiding memory leaks on error-recovery paths + + * Making reference counting thread safe + + * Exhaustive testing of memory allocation points + +Other fixes (Thanks, everybody!) +-------------------------------- +Cairo's internal fixed-point representation has been changed from +16.16 to 24.8. This has a direct impact on applications as it allows +much larger objects to be drawn before internal limits in cairo make +the drawing not work. + +The CAIRO_EXTEND_PAD mode is now fully supported by surface +patterns. This mode allows applications to use cairo_rectangle and +cairo_fill to draw scaled images with high-quality bilinear filtering +for the internal of the image, but without any objectionably blurry +edges, (as would happen with the default EXTEND_NONE and cairo_paint). + +Rendering with CAIRO_ANTIALIAS_NONE has been fixed to be more +predictable, (previously image rendering and geometry rendering would +be slightly misaligned with respect to each other). + +The reference manual at http://cairographics.org/manual now documents +100% of the functions and types in cairo's public API. + +API additions +------------- +Several small features have been added to cairo with new API functions: + +cairo_format_stride_for_width + + Must be called to compute a properly aligned stride value before + calling cairo_image_surface_create_for_data. + +cairo_has_current_point + + Allows querying if there is a current point defined for the + current path. + +cairo_path_extents + + Allows querying for path extents, (independent of any fill or + stroke parameters). + +cairo_surface_copy_page +cairo_surface_show_page + + Allow beginning a new document page without requiring a cairo_t + object. + +cairo_ps_surface_restrict_to_level +cairo_ps_get_levels +cairo_ps_level_to_string +cairo_ps_surface_set_eps + + Allow controlling the Post PostScript level, (2 or 3), to + target, as well as to generate Encapsulated PostScript (EPS). + +cairo_quartz_font_face_create_for_cgfont + + Create a quartz-specific cairo_font_face_t from a CGFontRef. + +cairo_win32_font_face_create_for_logfontw_hfont + + Create a win32-specific cairo_font_face from a LOGFONTW and an + HFONT together. + +Thanks, Everyone! +----------------- +I've accounted for 32 distinct people with attributed code added to +cairo between 1.4.14 and 1.6.0, (their names are below). That's an +impressive number, but there are certainly dozens more that +contributed with testing, suggestions, clarifying questions, and +encouragement. I'm grateful for the friendships that have developed as +we have worked on cairo together. Thanks to everyone for making this +all so much fun! + +Adrian Johnson, Alp Toker, Antoine Azar, Behdad Esfahbod, +Benjamin Otte, Bernardo Innocenti, Bertram Felgenhauer, +Boying Lu, Brian Ewins, Carl Worth, Chris Heath, Chris Wilson, +Claudio Ciccani, Emmanuel Pacaud, Jeff Muizelaar, Jeremy Huddleston, +Jim Meyering, Jinghua Luo, Jody Goldberg, Jonathan Gramain, +Keith Packard, Ken Herron, Kouhei Sutou, Kristian Høgsberg, +Larry Ewing, Martin Ejdestig, Nis Martensen, Peter Weilbacher, +Richard Hult, Shailendra Jain, Søren Sandmann Pedersen, +Vladimir Vukicevic + +Snapshot 1.5.20 (2008-04-04 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the tenth snapshot in cairo's unstable 1.5 series. It comes +just two days (and only one working day) after the 1.5.18 +snapshot. The quick snapshot is due to two embarrassing bugs (both +affecting cairo-xlib) that had been introduced in the 1.5.18 +snapshot. The fixes for these are described below along with a few +other fixes, (which hopefully aren't introducing new bugs this time). + +cairo-xlib +---------- +Revert fix from 1.5.18 to allow pattern expansion based on the filter +mode. This fix seemed so boring, (the use case it addresses is almost +never used in practice), that it didn't even get mentioned in the +1.5.18 release notes. However, the "fix" happened to break rendering +that is always used resulting in corrupt image rendering in mozilla, +evolution, and probably everything else that uses cairo. + +Fix to avoid BadMatch errors in cairo_surface_create_similar. These +were introduced, (inadvertently, of course), as part of the fix in +1.5.18 for creating similar surfaces without the Render +extension. Again, thanks to mozilla, (and Vladimir Vukicevic in +particular), for noticing our mistake. + +general +------- +Correctly handle an in-error surface in +cairo_surface_write_to_png. Previously this function would cause an +assertion failure if you gave it a finished surface. Now it cleanly +returns a CAIRO_STATUS_SURFACE_FINISHED result instead. + +Avoid potentially infinite wandering through memory inside +_cairo_hull_prev_valid. Thanks to Jonathan Watt for noticing this +problem: + + https://bugzilla.mozilla.org/show_bug.cgi?id=306649#c21 + +cairo-pdf +--------- +Fix generation of "soft" masks made by drawing to a similar surface +and then calling cairo_mask_surface() with it. + +cairo-svg +--------- +Fix for code that uses cairo_mask() on an intermediate surface which +is later passed to cairo_mask_surface(). + +Snapshot 1.5.18 (2008-04-05 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the ninth snapshot in cairo's unstable 1.5 series. It comes +just 4 days after the 1.5.16 snapshot. We had hoped to not need +another snapshot before the final 1.6.0 release, but several critical +bugs were found and fixed in the last few days, so we thought it +important to let people test the fixes with this snapshot. See below +for details. + +documentation +------------- +The README now lists necessary dependencies. + +Various graphics state defaults are now documented, (source pattern is +opaque black, line width is 2.0, line join is miter, line cap is butt, +miter limit is 10.0, etc.). + +general +------- +Several cleanups have been made along many error-path returns, +(carefully propagating up the original error status values, cleaning +up memory leaks during error recovery, etc.). This is yet another in +Chris "ickle" Wilson's long series of error-handling cleanups during +the 1.5 series. + +Avoid undesired clipping when drawing scaled surface patterns with +bilinear filtering. + +cairo-pdf +--------- +Fix emission of 1-bit alpha masks in PDF output. + +Fix a bug that would cause glyphs to be misplaced along the Y axis: + + http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=%23474136 + + Originally, an issue about a crash, but later leading to the + misplaced glyphs issue being discovered. + +cairo-ps +-------- +Fix misplaced glyphs in cairo's PostScript output. + + This issue occurs when consecutive glyphs are placed far + apart. This case is exercised by the new ft-show-glyphs-table test + case, which was originally inspired by the Debian bug #23474136 + mentioned above. + +Fix more misplaced glyphs in cairo's PostScript output: + + The issue here showed up under very particular circumstance, (when + converting a PDF file with a CFF font with CID Identity-H encoding + and using glyph 0, (defined by the CFF specification as .notdef) + as a space instead). More concretely, this problem appeared when + converting the UbuntuDesktop.pdf file mentioned in this bug + report: + + https://bugs.freedesktop.org/show_bug.cgi?id=15348#c3 + + As usual with arcane font-encoding-specific bugs like this, many + thanks to Adrian Johnson for his magical ability to dive into + specifications and emerge almost instantaneously with fixes. And + thanks to Sebastien Bacher for bringing the bug to our attention. + +cairo-xlib +---------- +Fix serious failure on X servers without the Render extension. + + Since the 1.5.14 snapshot (with support for PseudoColor visuals), + any application attempting to create a "similar" xlib surface would + fail on an X server without the Render extension. Thanks to + Frederic Crozat for pointing out that cairo's test suite was + entirely failing when run against Xvfb. + +Avoid crashing cairo-xlib applications for too-large glyphs + + Naively sending glyphs of any size to the X server will eventually + violate the X limit on maximum request sizes. We now properly + detect when a glyph would be too large and use existing fallbacks + to render the glyph rather than trying to send it to the X server. + +Enable the buggy_repeat workaround for Xorg servers < 1.4 + + We have determined that Xorg 1.3.0 (as packaged in Fedora 8 at + least) has a bug that can result in an X server crash when cairo + uses certain X Render repeat operations, (as exercised by cairo's + extend-reflect test). We avoid this crash by using fallbacks + whenever a repeating surface is needed for any Xorg server with a + version less than 1.4. This is slower, but should prevent the + crash. + + (Meanwhile, there appears to be a separate bug where some X + servers or specific X-server drivers will use random pixmap data + when asked to draw a repeating surface. The buggy_repeat + workaround would also avoid those problems, but we have not yet + characterized whether the new "version < 1.4" is a good + characterization of those problems or not.) + +cairo-quartz-font +----------------- +Implement cairo_font_extents for this backend. + +The cairo-quartz-font implementation added in the 1.5.14 snapshot was +entirely missing support for the cairo_font_extents function. Thanks to +Richard Hult for pointing out this obvious shortcoming, (and obvious +lack of coverage in our test suite): + + CGFont backend returns 0 font extents + https://bugs.freedesktop.org/show_bug.cgi?id=15319 + +Snapshot 1.5.16 (2008-04-01 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the eighth snapshot in cairo's unstable 1.5 series. It comes +less than two weeks after the 1.5.14 snapshot and it really is a +legitimate snapshot, (in spite of sharing this date with that of many +bogus announcements). The major change in this snapshot is that the +cairo-quartz backend is now officially "supported", including new API +to construct a font face from a CGFontRef . Also several bug fixes +have been fixed in many backends. See below for details. + +general +------- +Cairo now depends on pixman 0.10.0 which was recently released. The +latest pixman release can always be found alongside cairo releases at: + + http://cairographics.org/releases + +Increase the precision of color stops for gradients. This fixes a +regression in gradient rendering that had been present since the +1.5.12 snapshot. + +paginated (all of ps, pdf, svg, and win32-printing) +--------------------------------------------------- +Fix assertion failure when some drawing elements are outside the page +boundaries, (this bug was noticed when using Inkscape to print a +drawing with landscape orientation to a portrait-oriented piece of +paper). + +cairo-ps +-------- +Fix of bug causing incorrect glyph positioning. + +Fix handling of CAIRO_OPERATOR_SOURCE. + +cairo-pdf +--------- +More reduction of unnecessary digits of precision in PDF output. + +Fix handling of CAIRO_OPERATOR_SOURCE. + +cairo-svg +--------- +Fix bug in usage of libpng that was preventing cairo_mask from working +with the svg backend. + +Fix transformation of source pattern for cairo_stroke(). + +cairo-win32-printing +-------------------- +Fix fallback resolution, (thanks again to inkscape users/developers +for helping us find this one). + +cairo-quartz +------------ +Mark the cairo-quartz backend as "supported" rather than +"experimental". This means the following: + + * The backend will now be built by default (if possible). + + * We are committing that the backend-specific API (as published in + cairo-quartz.h) are stable and will be supported in all future + cairo 1.x releases. + + * We are committing that the output quality of this backend + compares favorably with other cairo backends, (and that quality + is ensured by good results from the cairo test suite). + + * We recommend that distributions build and distribute this + backend when possible. + +Note that the cairo_quartz_image API (in cairo-quartz-image.h) is +still experimental, will not build by default, (pass +--enable-quartz-image to configure to build it), and may see API +changes before it is marked as "supported" in a future release. + +Put the CAIRO_FONT_TYPE_ATSUI name back into +cairo-deprecated.h. Without this, the cairo 1.5.14 snapshot broke all +builds for applications using the C++ cairomm bindings (and perhaps +others) which have the CAIRO_FONT_TYPE_ATSUI name in their header +files. This breakage happened even for applications not using +cairo-quartz at all. + + Note: Even though the CAIRO_FONT_TYPE_ATSUI name is provided to + avoid this build breakage, we still recommend that bindings and + applications move to the new, and more accurate, + CAIRO_FONT_TYPE_QUARTZ name. + +Replace the implementation of cairo-quartz-font to use CFFont instead +of ATSUI. The CGFont API is a better fit than ATSUI, and this new +implementation is also more correct than the old one as well. + +This also adds the following new API call: + + cairo_public cairo_font_face_t * + cairo_quartz_font_face_create_for_cgfont (CGFontRef font); + +The previous cairo_quartz_font_face_create_for_atsu_font_id function +continues to exist and is part of the supported API going +forward. (However, the old name of that same function, which was +cairo_atsui_font_face_create_for_atsu_font_id is officially +deprecated. Any source code using the old name should be updated to +use the new name.) + +Fix transformation of source pattern for cairo_stroke(). + +cairo-win32 +----------- +Avoid crash in create_similar is cairo_win32_surface_create fails. + +Snapshot 1.5.14 (2008-03-20 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the seventh snapshot in cairo's unstable 1.5 series. It comes +3 weeks after the 1.5.12 snapshot. This snapshot includes support for +arbitrary X server visuals, (including PseudoColor), which was the +final remaining cairo-specific item on the cairo 1.6 roadmap. It also +includes a huge number of improvements to the cairo-quartz backend. So +this is effectively a cairo 1.6 release candidate. We expect very few +changes from now until 1.6 and only for specific bug fixes. + +API Change +---------- +Rename ATSUI font backend to Quartz font backend. This affects the +following usage: + + --enable-atsui -> --enable-quartz-font + CAIRO_HAS_ATSUI_FONT -> CAIRO_HAS_QUARTZ_FONT + CAIRO_FONT_TYPE_ATSUI -> CAIRO_FONT_TYPE_QUARTZ + + cairo_atsui_font_face_create_for_atsu_font_id -> + cairo_quartz_font_font_create_for_atsu_font_id + +This API change is justified by the cairo-quartz backend still be +marked as "experimental" rather than "supported", (though this is one +step toward making the change to "supported" before 1.6). Cairo will +still provide ABI compatibility with the old symbol name, however. + +paginated (all of ps, pdf, svg, and win32-printing) +--------------------------------------------------- +Optimize by not analyzing an image surface for transparency more than +once, (previously all images were analyzed twice). + +cairo-ps and cairo-pdf +---------------------- +Avoiding emitting a matrix into the stroke output when unnecessary, +(making output size more efficient). + +Reduce rounding error of path shapes by factoring large scale factors +out of the path matrix, (ensuring that a fixed-number of printed +digits for path coordinates contains as much information as possible). + +Reduce excess digits for text position coordinates. This makes the +output file size much smaller without making the result any less +correct. + +cairo-ps +-------- +Eliminate bug causing extraneous text repetition on Linux PostScript +output in some cases. + + See: Mozilla Bug 419917 – Printed page contents are reflected + inside bordered tables (Linux-only) + + https://bugzilla.mozilla.org/show_bug.cgi?id=419917 + +Optimize output when EXTEND_PAD is used. + +cairo-pdf +--------- +Fix to not use fill-stroke operator with transparent fill, (else PDF +output doesn't match the cairo-defined correct result). See: + + https://bugs.launchpad.net/inkscape/+bug/202096 + +cairo-svg +--------- +Fix stroke of path with a non-solid-color source pattern: + + http://bugs.freedesktop.org/show_bug.cgi?id=14556 + +cairo-quartz +------------ +Fix text rendering with gradient or image source pattern. + +Handling antialiasing correctly for cairo_stroke(), cairo_clip(), and +cairo_show_text()/cairo_show_glyphs(). + +Correctly handle gradients with non-identity transformations: + + Fixes http://bugs.freedesktop.org/show_bug.cgi?id=14248 + +Add native implementation of REPEAT and REFLECT extend modes for +gradients. + +Fix implementation for the "unbounded" operators, (CAIRO_OPERATOR_OUT, +_IN, _DEST_IN, and _DEST_ATOP). + +Correctly handle endiannees in multi-architecture compiles on Mac OS +X. + +Avoid behavior which would cause Core Graphics to print warnings to +the console in some cases. + +cairo-win32 +----------- +Fix handling of miter limit. + +cairo-win32-printing +-------------------- +Fix to not use a 1bpp temporary surface in some cases while printing, +(so grayscale data is preserved rather than just becoming black and +white). + +cairo-xlib +---------- +Add support for rendering to arbitrary TrueColor X server +visuals. This fixes at least the following bugs: + + cairo doesn't support 8-bit truecolor visuals + https://bugs.freedesktop.org/show_bug.cgi?id=7735 + + cairo doesn't support 655 xlib format + https://bugs.freedesktop.org/show_bug.cgi?id=9719 + +Add support for rendering to 8-bit PseudoColor X server visuals. This +fixes the following bug: + + Cairo doesn't support 8-bit pseudocolor visuals + https://bugs.freedesktop.org/show_bug.cgi?id=4945 + +Snapshot 1.5.12 (2008-02-28 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the sixth snapshot in cairo's unstable 1.5 series. It comes 1 +week after the 1.5.10 snapshot. This snapshot includes the +long-awaited change from 16.16 to 24.8 fixed-point values, (see below +for why you should care). It also includes several backend-specific +bug fixes. + +24.8 fixed-point format +----------------------- +Cairo has always converted path coordinates to a fixed-point +representation very early in its processing. Historically, this has +been a 32-bit representation with 16 bits of integer for the +device-pixel grid and 16 bits of sub-pixel positioning. The choice of +16 bits for the integer coordinate space was based on the 16-bit limit +for X Window drawables. + +This 16-bit limit has proven problematic for many applications. It's +an especially vexing problem when targeting non-X backends that don't +have any 16-bit restriction. But even when targeting cairo-xlib, it's +often desirable to draw a large shape, (say a background rectangle), +that extends beyond the surface bounds and expect it to fill the +surface completely, (rather than overflowing and triggering random +behavior). + +Meanwhile, nobody has ever really needed 16 bits of sub-pixel +precision. + +With this snapshot, the fixed-point system is still in place and is +still using a 32-bit representation, (future versions of cairo might +move entirely to floating-point when targeting PDF output for +example). But the representation now provides 24 bits of pixel +addressing and only 8 bits of sub-pixel positioning. This should give +a much less stifling space to many applications. + +However, the underlying pixman library still has 16-bit limitations in +many places, (it has its roots in the X server as well). Until those +are also fixed, applications targeting cairo image surfaces, or +hitting software fallbacks when targeting other surfaces will still +encounter problems with device-space values needing more than 16 +integer bits. + +generic fixes +------------- +Add a few tests to the test suite to increase coverage. + +Cleanup a few error-handling paths, (propagate error correctly). + +cairo-ft +-------- +Fix handling of font sizes smaller than 1 device pixel. + +cairo-pdf +--------- +Fix to properly save/restore clip when analyzing meta-surface +patterns, (fixing a couple of test-suite failures). + +Implement native support for CAIRO_OPERATOR_SOURCE when the source +pattern is opaque. + +Emit rectangles as PDF rectangles ("re" operator) rather than as +general paths. + +cairo-ps +-------- +Fix to work properly with the 16.16->24.8 change. + +cairo-svg +--------- +Fix CAIRO_EXTEND_REFLECT by using an image fallback, (there's no +direct SVG support for reflected patterns). + +Fix the use of alpha-only masks, (such as CAIRO_FORMAT_A8). + +cairo-quartz +------------ +Add new API for efficiently using image data as a source: + + cairo_surface_t * + cairo_quartz_image_surface_create (cairo_surface_t *image_surface); + + cairo_surface_t * + cairo_quartz_image_surface_get_image (cairo_surface_t *surface); + +For full documentation, see: + + http://cairographics.org/manual/cairo-Quartz-Surfaces.html#cairo-quartz-image-surface-create + +Several fixes for cairo_mask(). + +cairo-atsui +----------- +Change default from from Monaco to Helvetica to be more consistent +with other font backends. + +Snapshot 1.5.10 (2008-02-20 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the fifth snapshot in cairo's unstable 1.5 series. It comes 3 +weeks after the 1.5.8 snapshot. This snapshot adds one new API +function, (cairo_has_current_point), and the usual mix of +improvements, (more efficient PostScript/PDF output, optimized +stroking), and fixes (more robust error-handling, etc.). See below for +details. + +New API +------- +Add a new function to query if there is a current point: + + cairo_bool_t + cairo_has_current_point (cairo_t *cr); + +There is no current point immediately after cairo_create(), nor after +cairo_new_path() or cairo_new_sub_path(). There is a current point +after any of the path-creation functions, (cairo_move_to, +cairo_line_to, cairo_curve_to, etc.). + +With this new function, we also revert the change of the return type +of cairo_get_current_point from cairo 1.5.8, (it's now a void function +again). + +Optimizations +------------- +Optimize stroking code to avoid repeated calculation of redundant +values, (particularly significant for very large, offscreen paths). + +General fixes +------------- +Patch a few more potential buffer overruns, (due to integer +overflow). + +Many fixes and improvements to cairo's error-handling, (ensure that +correct error values are returned, clean up memory leaks on +error-handling paths, etc.). + +Fix a potential infinite loop when stroking a spline with a pen that +has been transformed to a line segment. + +Remove treating NULL as a synonym for a valid cairo_font_options_t* +with default values, (a change that had been introduced as of cairo +1.5.8). + +Remove the altered handling of tolerance and fallback-resolution that +had been introduced as of cairo 1.5.4. + +cairo-xlib +---------- +Pass the original Drawable, (as opposed to the root window), to +XCreatePixmap when creating a similar surface. This gives the X server +more information so that it can be clever and efficient. + +cairo-pdf +--------- +Fix the rendering of repeating and reflecting patterns. + +Ensure miter limit is always >= 1, (smaller limits are not meaningful, +but they can cause some PDF viewers to fail to display pages). + +Generate more efficient output when the same path is used for both +fill and stroke. + +cairo-ps +-------- +Start sharing much of the cairo-pdf code rather than implementing very +similar code in cairo-ps. + +Implement native support for repeating and reflecting linear +gradients. + +Implement reflected surface patterns. + +Ensure miter limit is always >= 1, (smaller limits are not meaningful, +but they can cause some PostScript viewers to crash). + +Generate PostScript that will perform more efficiently and use less +memory on printers, (use currentfile instead of a giant string array +for image data, and avoid using PostScript patterns for paint() and +fill() when possible). + +cairo-svg +--------- +Avoid unnecessary rasterization when copying a "similar" surface to +another svg surface, (allow the SOURCE operator to be implemented with +all-vector operations if there are no underlying objects). + +cairo-atsui +----------- +Eliminate infinite loop when attempting to render an empty string. + +Snapshot 1.5.8 (2008-01-30 Carl Worth <cworth@cworth.org>) +========================================================== +This is the fourth snapshot in cairo's unstable 1.5 series. It comes 2 +weeks after the 1.5.6 snapshot. It adds a few new API functions. Most +notably all callers of cairo_image_surface_create_for_data should now +be calling cairo_format_stride_for_width to compute a legal stride +value. See below for more details. + +New API in cairo 1.5.8 +---------------------- +We've added a new function that should be called to compute a legal +stride value before allocating data to be used with +cairo_image_surface_create_for_data: + + int + cairo_format_stride_for_width (cairo_format_t format, + int width); + +We've also added a new cairo_path_extents function that can be used to +compute a bounding box for geometry such as a single line segment, +(contrast with cairo_path_extents and cairo_stroke_extents): + + void + cairo_path_extents (cairo_t *cr, + double *x1, double *y1, + double *x2, double *y2); + +And finally, we've added a function to allow for querying the +XRenderPictFormat of a cairo-xlib surface: + + XRenderPictFormat * + cairo_xlib_surface_get_xrender_format (cairo_surface_t *surface); + +API changes +----------- +Fix return types of cairo_surface_show_page and +cairo_surface_copy_page. This is an API change to functions that are +new in the 1.5 series, so not an API break compared to any stable +cairo release, (1.0.x, 1.2.x, 1.4.x). + +Change the return type of cairo_get_current_point() from void to +cairo_status_t. This allows the caller to receive a +CAIRO_STATUS_NO_CURRENT_POINT value to distinguish the a current point +at the origin from no current point existing. + +Performance improvement +----------------------- +Improve performance of clipping by using an optimized code path +internally, (with the ADD operator instead of IN). + +General bug fixes +----------------- +Fix various cairo_*_extents functions to initialize the return-value +variables even in the case of a cairo_t in error. + +Treat NULL as a legitimate value for cairo_font_options_t*. [NOTE: +On discussion afterwards, we decided against this change so it has +been removed as of cairo 1.5.10.] + +Fix rendering with CAIRO_ANTIALIAS_NONE to be more predictable, (that +is, to avoid seams appearing when geometry and imagery share an +identical edge). Portions of this fix are in the pixman library and +will appear in a future release of that library. + +Avoid triggering an error for a font size of 0. + +Miscellaneous changes +--------------------- +Require pixman >= 0.9.6. + +There has been a tremendous amount improvement to cairo's +documentation. We're delighted that 100% of the public API has at +least some documentation in the API reference manual. Many thanks to +Behdad Esfahbod and Nis Martensen for leading this effort. + +cairo-pdf and cairo-ps +---------------------- +Eliminate failure when a Type 1 font is embedded with an explicit +glyph 0. + +cairo-pdf +--------- +Implement a more correct and more efficient approach for patterns with +an extend mode of CAIRO_EXTEND_REFLECT. + +cairo-ps +-------- +Fix image masks to properly pack and pad mask bits. + +cairo-quartz +------------ +Take care to only use DrawTiledImage for integer-aligned images, (and +use slower paths to get the correct result in other cases). + +cairo-win32 +----------- +Fix for older versions of mingw. + +Improve the handling of the clipping with the win32 and win32-printing +surfaces. + +Fix rendering of non black/white text. + +Snapshot 1.5.6 (2008-01-15 Carl Worth <cworth@cworth.org>) +========================================================== +This is the third snapshot in cairo's unstable 1.5 series. It comes +about 6 weeks after the 1.5.4 snapshot. The only API addition compared +to 1.5.4 is very minor, (a new value CAIRO_STATUS_TEMP_FILE_ERROR). +The remainder of the changes are the usual accumulation of bug fixes +and improvements. See below for details. + +General bug fixes +----------------- +Fix handling of fonts that contain a mixture of outline and bitmapped +glyphs. There was a change in this handling in 1.5.4 that improved +some cases and also regressed other cases. Now, all cases should be +handled quite well. + +Fix alignment issues that were causing SIGBUS failures on SPARC. + +Fix a regression (which first appeared in 1.5.2) where stroking under +a large scale would sometimes incorrectly replace a miter join with a +bevel join. (Thanks to Keith Packard.) + +Fix reporting of zero-sized extents to be {0,0} rather than +{INT_MAX,INT_MIN}. This avoids several integer overflow and +allocations of massive regions in some cases. + +Fix failures of gradients with no stops, (quartz, ps, and pdf). + +Fix handling of Type 1 fonts on Windows platforms. + +Fix handling of Type 1 fonts with no specific family name in the font +itself, (generate a CairoFont-x-y name). + +Handle NULL string values in cairo_show_text, cairo_show_glyphs, and +friends. + +Many robustness improvements along error-handling paths, (thanks as +always, to Chris "ickle" Wilson). + +Various other minor fixes. + +Paginated backends (PDF/PostScript/win32-printing) +-------------------------------------------------- +Avoid unnecessary rasterization when using a paginated surface as a +source, (such as drawing from one pdf surface to another). + +Fix replaying of paginated surface with more than one level of push/pop +group. + +cairo-xlib +---------- +Fix xlib backend to not consider recent X server release as having a +buggy repeat implementation in the Render extension. + +cairo-pdf +--------- +Fix PDF output to avoid triggering very slow rendering in PDF viewers, +(avoid starting and stopping the content stream for each pattern +emission). + +Support CAIRO_OPERATOR_SOURCE in cases where there is nothing below +the object being drawn. + +Fix to avoid seams appearing between multiple fallback regions. + +cairo-ps (PostScript) +--------------------- +Use correct bounding box in Type 3 fonts. + +Fix several bugs in cairo's PostScript output. These include making +the PostScript output more compatible with recent versions of +ghostscript that are more strict about Type 3 fonts, for +example. + +Fix for win32 to not attempt to create temporary files in the root +directory, (where the user may not have write permission). + +Avoid generating Level 3 PostScript if Level 2 is sufficient. Also, +add code in output documents to alert the user if Level 3 PostScript +is handed to a device that cannot handle PostScript beyond Level +2. + +cairo-directfb +-------------- +Various performance optimizations. + +Fixed support for small surfaces (less than 8x8). + +Provide support for environment variables CAIRO_DIRECTFB_NO_ACCEL to +disable acceleration and CAIRO_DIRECTFB_ARGB_FONT to enable ARGB fonts +instead of A8. + +cairo-os2 +--------- +Allow OS/2 APIs instead of C library allocation functions. + +Snapshot 1.5.4 (2007-12-05 Carl Worth <cworth@cworth.org>) +========================================================== +This is the second snapshot in cairo's unstable 1.5 series. It comes +just over 1 month after the 1.5.2 snapshot. There are no API changes +or additions in 1.5.4 compared to 1.5.2, but there are several bug +fixes, and some optimizations. Most of these apply to particular +backends. See below for details. + +General improvements +-------------------- +Use less memory for spline approximation calculations. + +Change how the tolerance value is interpreted with regard to +fallback-resolution. [Note: On further discussion, we decided against +this change for now. It is removed as of cairo 1.5.10.] + +Fix precision of floating-point values in vector-output backends to +avoid rounding errors with very small numbers. + +Xlib improvements +----------------- +Fix bug in glyph rendering with xlib, (due to everything being clipped +out). This was a regression in the 1.5.2 snapshot that was visible in +the GIMP, for example. See: + + cairo 1.5.2 causes font problems in GIMP 2.4 status bar and evolution 2.12.1 + https://bugs.freedesktop.org/show_bug.cgi?id=13084 + +PostScript improvements +----------------------- +Fix bug leading to invalid PostScript files when rendering +text, (need "0 0 xyshow" instead of "0 xyshow"). + +Fix many issues with Type 3 fonts, including making the resulting text +extractable. + +Quartz improvements +------------------- +Fix font metrics height value for ATSUI, (helps webkit on GTK+ OS X +layout nicely). + +Fix gradients. + +Fix EXTEND_NONE mode for patterns. + +Fix cairo_quartz_surface_create to properly clear the new surface +in cairo_quartz_surface_create. + +Fix to correctly handle 0x0 sized surfaces. + +Optimize drawing of EXTEND_REPEAT patterns for OS X 10.5. + +Snapshot 1.5.2 (2007-10-30 Carl Worth <cworth@cworth.org>) +========================================================== +This is the first snapshot in cairo's unstable 1.5 series. It comes 4 +months after the 1.4.10 release. This snapshot includes significant +improvements to PDF and PostScript output, which is one of the things +in which we're most interested in getting feedback. There are a couple +of minor API additions, and several optimizations, (primarily in the +"print/vector" backends). And there are dozens of bug fixes and +robustness improvements. + +New dependency on external pixman library +----------------------------------------- +A significant change in this snapshot compared to all previous cairo +releases is that cairo now depends on an external "pixman" library for +its software rendering. Previously this same code was compiled +internally as part of cairo, but now the code is separate so that both +cairo and the X server can now share common code, (thanks very much to +Søren Sandmann for his work on separating pixman and maintaining it). + +So users will need to acquire and build pixman before being able to +build cairo. The current release is 0.9.6 and can be obtained from +here: + + http://cairographics.org/releases/pixman-0.9.6.tar.gz + + which can be verified with: + + http://cairographics.org/releases/pixman-0.9.6.tar.gz.sha1 + 66f01a682c64403a3d7a855ba5aa609ed93bcb9e pixman-0.9.6.tar.gz + + http://cairographics.org/releases/pixman-0.9.6.tar.gz.sha1.asc + (signed by Carl Worth) + +Major PDF/PostScript improvements +--------------------------------- +Adrian Johnson has done some long-awaited work to make cairo's PDF and +PostScript output more interesting than ever before. First, many +operations that previously triggered image fallbacks will now be +rendered as native vectors. These operations include: + + PDF: cairo_push_group, cairo_surface_create_similar, + cairo_mask, A8/A1 surface sources, repeating/reflecting linear + gradients. + + PostScript: cairo_push_group, cairo_surface_create_similar, + gradients, bilevel alpha masks, (for example, all values either 0 or + 255 for an A8 mask). + +Not only that, but when an image fallback is required, it will now be +limited to only the necessary region. For example, a tiny translucent +image overlaying a small portion of text would previously caused an +entire PostScript page to be rendered as a giant image. Now, the +majority of that page will be nice text, and there will only be a tiny +image in the output. + +Additionally, the PostScript output now carefully encodes text so that +if it is subsequently converted to PDF, the text will be +selectable. + +This is very exciting progress, and we're hoping to hear from users +during the 1.5 series about how things have improved, (for example, +inkscape users doing cairo-based PDF export: please let us know how +things look). And feel free to pass your thanks along to Adrian for his excellent work. + +NOTE: This much improved PDF output makes more sophisticated use of +functionality in the PDF specification. This means that cairo's output +will sometimes expose bugs in some free software PDF viewers, (evince, +poppler, and xpdf, for example), that are not yet ready for such PDF +files. We're working with the poppler maintainers to get these bugs +fixed as quickly as possible. In the meantime, please double-check +with other PDF viewers if cairo-generated PDF files are not being +rendered correctly. It may be due to a bug in the viewer rather than +in the PDF file that cairo has created. + +Robustness improvements +----------------------- +Chris Wilson has made the largest contribution by far to cairo 1.5.2, +(in number of commits). His more than 150 commits include a huge +number of fixes to increase cairo's robustness. These fixes make cairo +more robust against invalid and degenerate input, (NaN, empty path, +etc.), against size-0 malloc calls, against memory leaks on +error-recovery paths, and against other failures during error +handling. He also implemented atomic operations to cairo, and used +them to fix cairo's previously non-thread-safe reference counting, +again improving robustness. + +Chris has put a tremendous amount of time and effort into writing +analysis tools for this work, and in running those tools and fixing +the problems they report. We're very grateful for this work, and hope +that all cairo users appreciate the more robust implementation that +results from it. + +This work is largely thankless, so it might make sense to notice +sometime that cairo has been running quite smoothly for you, and when +you do, send a quick "thank you" off to Chris Wilson, since it +is all definitely running smoother thanks to his work. + +New API +------- +There are no major additions to cairo's core API. The only new, +generic functions are: + + void + cairo_surface_copy_page (cairo_surface_t *surface); + + void + cairo_surface_show_page (cairo_surface_t *surface); + +which can now be used much more conveniently than the existing +cairo_copy_page and cairo_show_page functions in some +situations. These functions act identically, but require only a +cairo_surface_t* and not a cairo_t*. + +All other API additions are specific to particular backends. + +New cairo-win32 API (new font face function and "win32 printing" surface) +------------------------------------------------------------------------- +There is a new function for creating a win32 font face for both a +logfontw and an hfont together. This complements the existing +functions for creating a font face from one or the other: + + cairo_font_face_t * + cairo_win32_font_face_create_for_logfontw_hfont (LOGFONTW *logfont, + HFONT font); + +There is also a new "win32 printing" surface: + + cairo_surface_t * + cairo_win32_printing_surface_create (HDC hdc); + +This interface looks identical to the original +cairo_win32_surface_create, (both accept and HDC), but the behavior of +this new surface is very different. It should only be called with a +printing DC, and will result in all drawing commands being stored into +a meta-surface and emitted after each page is complete, with analysis +to do as minimal image-based fallbacks as necessary. The behavior and +implementation shares much with the PDF and PostScript backends. + +New cairo-ps API (EPS and PostScript level control) +--------------------------------------------------- +An often requested feature has been the ability to generate +Encapsulated PostScript (EPS) with cairo. We have that now with the +following very simple API. Just do cairo_ps_surface_create as usual +then call this function with a true value: + + void + cairo_ps_surface_set_eps (cairo_surface_t *surface, + cairo_bool_t eps); + +[NOTE: As always with snapshots, it's possible---though not very +likely---that the API could still be modified before a final +release. For example, this is the first public cairo function that +accepts a Boolean parameter. I'm generally opposed to Boolean +parameters, but this is probably the one case where I'm willing to +accept one, (namely a "set" function that accepts a single Boolean).] + +Also, it is now possible to control what PostScript level to target, +(either level 2 or level 3), with the following new API: + + typedef enum _cairo_ps_level { + CAIRO_PS_LEVEL_2, + CAIRO_PS_LEVEL_3 + } cairo_ps_level_t; + + void + cairo_ps_surface_restrict_to_level (cairo_surface_t *surface, + cairo_ps_level_t level); + + void + cairo_ps_get_levels (cairo_ps_level_t const **levels, + int *num_levels); + + const char * + cairo_ps_level_to_string (cairo_ps_level_t level); + +Improvement for cairo-quartz +---------------------------- +Brian Ewins had contributed several improvements to cairo-quartz. These +include an implementation of EXTEND_NONE for linear and radial +gradients, (so this extend mode will no longer trigger image fallbacks +for these gradients), as well as native surface-mask clipping, (only +on OS X 10.4+ where the CGContextClipToMask function is available). + +He also fixed a semantic mismatch between cairo and quartz for dashing +with an odd number of entries in the dash array. + +We're grateful for Brian since not many quartz-specific improvements +to cairo would be happening without him. + +Optimizations +------------- +Optimize SVG output for when the same path is both filled and stroked, +and avoid unnecessary identity matrix in SVG output. (Emmanuel Pacaud). + +Optimize PS output to take less space (Ken Herron). + +Make PS output more compliant with DSC recommendations (avoid initclip +and copy_page) (Adrian Johnson). + +Make PDF output more compact (Adrian Johnson). + +Release glyph surfaces after uploading them to the X server, (should +save some memory for many xlib-using cairo application). (Behdad +Esfahbod). + +Optimize cairo-win32 to use fewer GDI objects (Vladimir Vukicevic). + +win32-printing: Avoid falling back to images when alpha == 255 +everywhere. (Adrian Johnson). + +win32-printing: Avoid falling back for cairo_push_group and +cairo_surface_create_similar. (Adrian Johnson) + +Bug fixes +--------- +Avoid potential integer overflows when allocating large buffers +(Vladimir Vukicevic). + +Preparations to allow the 16.16 fixed-point format to change to +24.8 (Vladimir Vukicevic). + +Fix bugs for unsupported X server visuals (rgb565, rgb555, bgr888, and +abgr8888). (Carl Worth and Vladimir Vukicevic) + +Fix bugs in PDF gradients (Adrian Johnson). + +Fix cairo-xlib to build without requiring Xrender header +files (Behdad Esfahbod). + +Make cairo more resilient in the case of glyphs not being available in +the current font. (Behdad Esfahbod) + +Prevent crashes when both atsui and ft font backends are compiled in +(Brian Ewins). + +Make font subsetting code more robust against fonts that don't include +optional tables (Adrian Johnson). + +Fix CFF subsetting bug, (which manifested by generating PDF files that +Apple's Preview viewer could not read) (Adrian Johnson). + +Fixed error handling for quartz and ATSUI backends (Brian Ewins). + +Avoid rounding problems by pre-transforming to avoid integer-only +restrictions on transformation in GDI (Adrian Johnson). + +Fixed an obscure bug (#7245) computing extents for some stroked +paths (Carl Worth). + +Fix crashes due to extreme transformation of the pen, (seems to show +up in many .swf files for some reason) (Carl Worth). + +Release 1.4.10 (2007-06-27 Carl Worth <cworth@cworth.org>) +========================================================== +This is the fifth update in cairo's stable 1.4 series. It comes +roughly three weeks after the 1.4.8 release. The most significant +change in this release is a fix to avoid an X error in certain cases, +(that were causing OpenOffice.org to crash in Fedora). There is also a +semantic change to include child window contents when using an xlib +surface as a source, an optimization when drawing many rectangles, and +several minor fixes. + +Eliminate X errors that were killing OO.o (Chris Wilson) +-------------------------------------------------------- +Cairo is fixed to avoid the X errors propagated when cleaning up +Render Pictures after the application had already destroyed the +Drawable they reference. (It would be nice if the X server wouldn't +complain that some cleanup work is already done, but there you have +it.) This fixes the bug causing OpenOffice.org to crash as described +here: + + XError on right click menus in OOo. + https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=243811 + +Use IncludeInferiors when using xlib surface as a source (Ryan Lortie) +---------------------------------------------------------------------- +When an xlib surface is used as the source of a draw operation the +contents of child windows are now included in the source data. The +semantics of drawing to xlib surfaces are unchanged (ie: draws are +still clipped by child windows overlapping the destination window). + +Optimize drawing of many rectangles (Vladimir Vukicevic) +-------------------------------------------------------- +Avoid O(N*N) loop when filling many axis-aligned rectangles, (either +many rectangles as separate sub-paths or due to dashing). + +Miscellaneous fixes +------------------- +Fix cairo-perf on Solaris by linking to librt. (Behdad Esfahbod) + +Fix make check for systems that require executable files to have a +particular extension. (Behdad Esfahbod) + +Eliminate some warnings in cairo-quartz. (Brian Ewins) + +Fix build-breaking typo for cairo-directfb. (Chris Wilson) + +Release 1.4.8 (2007-06-07 Carl Worth <cworth@cworth.org>) +========================================================= +This is the fourth update in cairo's stable 1.4 series. It comes just +over five weeks after the 1.4.6 release. This release includes a +thread-safe surface-cache for solid patterns which significantly +improves text rendering with the xlib backend. Also, dozens of error +paths in cairo have been fixed thanks to extensive fault-injection +testing by Chris Wilson. + +Surface cache for solid patterns +-------------------------------- +Originally written by Jorn Baayen, the introduction of a small cache +for surfaces created for solid patterns improves performance +dramatically. For example, this reduces the volume of X requests +during text rendering to the same level as Xft. + +This cache first made its appearance in a 1.3.x snapshot, but was +removed before appearing in any previous major release due to +complications with multi-threaded programs. For example, programs like +evince that would carefully restrict usage of cairo-xlib to a single +thread were unpleasantly surprised to find that using cairo-image in a +separate thread could trigger X requests. + +Behdad Esfahbod designed a fix which was implemented by Chris +Wilson. Now, the necessary X requests are queued up until the next +time the application directly operates on an xlib surface. + +Improved error handling paths +------------------------------ +Chris Wilson continued the excellent work he started in cairo 1.4.4 to +make cairo much more robust against out-of-memory and other errors. He +applied his memory allocation fault injection cairo's main test suite, +(previously he had applied it to cairo's performance suite). + +Chris's testing found dozens of bugs which he fixed. Many of these +bugs had perhaps never been hit by any users. But at least one was +hit by the gnome-about program which resulted in dozens of duplicated +bug reports against that program: + + http://bugzilla.gnome.org/show_bug.cgi?id=431990 + +We were very pleasantly surprised to see this bug get fixed as a +side-effect of Chris's work. Well done, Chris! + +Other fixes +----------- +Cleanup of mutex declarations (Behdad Esfahbod) + +Remove unnecessary clip region from SVG output (Emmanuel Pacaud) + +Remove Xsun from the buggy_repeat blacklist (Elaine Xiong) + +ATSUI: Fix glyph measurement: faster and more correct (Brian Ewins) + +Quartz: fixed 'extend' behaviour for patterns, improved pattern performance, +and a few smaller correctness fixes. (Brian Ewins, Vladimir Vukicevic) + +Release 1.4.6 (2007-05-01 Carl Worth <cworth@cworth.org>) +========================================================= +This is the third update in cairo's stable 1.4 series. It comes a +little less than three weeks since the 1.4.4 release. This release +fixes the broken mutex initialization that made cairo 1.4.4 unusable +on win32, OS/2, and BeOS systems. This release also adds significant +improvements to cairo's PDF backend, (native gradients!), and a couple +of performance optimizations, (one of which is very significant for +users of the xlib backend). See below for more details. + +Repaired mutex initialization +----------------------------- +We apologize that cairo 1.4.4 did little more than crash on many +platforms which are less-frequently used by the most regular cairo +maintainers, (win32, OS/2, and BeOS). The mutex initialization +problems that caused those crashes should be fixed now. And to avoid +similar problems in the future, we've now started posting pre-release +snapshots to get better testing, (subscribe to cairo@cairographics.org +if you're interested in getting notified of those and testing them). + +PDF Improvements +---------------- +Thanks to Adrian Johnson, (cairo PDF hacker extraordinaire), we have +several improvements to cairo's PDF backend to announce: + +Native gradients: + + As of cairo 1.4.6, cairo will now generate native PDF gradients in + many cases, (previously, the presence of a gradient on any page + would force rasterized output for that page). Currently, only + gradients with extend types of PAD (the default) or NONE will + generate native PDF gradients---others will still trigger + rasterization, (but look for support for other extend modes in a + future release). Many thanks to Miklós Erdélyi as well, who did the + initial work for this support. + +Better compatibility with PDF viewers: + + The PDF output from cairo should now be displayed correctly by a + wider range of PDF viewers. Adrian tested cairo's PDF output against + many PDF viewers, identified a common bug in many of those viewers + (ignoring the CTM matrix in some cases), and modified cairo's output + to avoid triggering that bugs (pre-transforming coordinates and + using an identity matrix). + +Better OpenType/CFF subsetting: + + Cairo will now embed CFF and TrueType fonts as CID fonts. + +Performance optimizations +------------------------- +Faster cairo_paint_with_alpha: + + The cairo_paint_with_alpha call is used to apply a uniform alpha + mask to a pattern. For example, it can be used to gradually fade an + image out or in. Jeff Muizelaar fixed some missing/broken + optimizations within the implementation of this function resulting + in cairo_paint_with_alpha being up to 4 times faster when using + cairo's image backend. + +Optimize rendering of "off-screen" geometry: + + Something that applications often do is to ask cairo to render + things that are either partially or wholly outside the current clip + region. Since 1.4.0 the image backend has been fixed to not waste + too much time in this case. But other backends have still been + suffering. + + In particular, the xlib backend has often performed quite badly in + this situation. This is due to a bug in the implementation of + trapezoid rasterization in many X servers. + + Now, in cairo 1.4.6 there is a higher-level fix for this + situation. Cairo now eliminates or clips trapezoids that are wholly + or partially outside the clip region before handing the trapezoids + to the backend. This means that the X server's performance bug is + avoided in almost all cases. + + The net result is that doing an extreme zoom-in of vector-based + objects drawn with cairo might have previously brought the X server + to its knees as it allocated buffers large enough to fit all of the + geometry, (whether visible or not). But now the memory usage should + be bounded and performance should be dramatically better. + +Miscellaneous +------------- +Behdad contributed an impressively long series of changes that +organizes cairo's internals in several ways that will be very +beneficial to cairo developers. Thanks, Behdad! + +Behdad has also provided a utility for generating malloc statistics, +(which was used during the great malloc purges of 1.4.2 and +1.4.4). This utility isn't specific to cairo so may be of benefit to +others. It is found in cairo/util/malloc-stats.c and here are Behdad's +notes on using it: + + To build, do: + + make malloc-stats.so + + inside util/, and to use, run: + + LD_PRELOAD=malloc-stats.so some-program + + For binaries managed by libtool, eg, cairo-perf, do: + + ../libtool --mode=execute /bin/true ./cairo-perf + LD_PRELOAD="../util/malloc-stats.so" .libs/lt-cairo-perf + +Finally, the cairo-perf-diff-files utility was enhanced to allow for +generating performance reports from several runs of the same backend +while some system variables were changed. For example, this is now +being used to allow cairo-perf to measure the performance of various +different acceleration architectures and configuration options of the +X.org X server. + +Release 1.4.4 (2007-04-13 Carl Worth <cworth@cworth.org>) +========================================================= +This is the second update release in cairo's stable 1.4 series. It +comes just less than a month after 1.4.2. The changes since 1.4.2 +consist primarily of bug fixes, but also include at least one +optimization. See below for details. + +Of all the work that went into the 1.4.4 release + +There have been lots of individuals doing lots of great work on cairo, +but two efforts during the 1.4.4 series deserve particular mention: + +Internal cleanup of error handling, (Chris Wilson) +-------------------------------------------------- +Chris contributed a tremendous series of patches (74 patches!) to +improve cairo's handling of out-of-memory and other errors. He began +by adding gcc's warn_unused_attribute to as many functions as +possible, and then launched into the ambitious efforts of adding +correct code to quiet the dozens of resulting warnings. + +Chris also wrote a custom valgrind skin to systematically inject +malloc failures into cairo, and did all the work necessary to verify +that cairo's performance test suite runs to completion without +crashing. + +The end result is a much more robust implementation. Previously, many +error conditions would have gone unnoticed and would have led to +assertion failures, segmentation faults, or other harder-to-diagnose +problems. Now, more than ever, cairo should cleanly let the user know +of problems through cairo_status and other similar status +functions. Well done, Chris! + +More malloc reduction, (Mathias Hasselmann) +------------------------------------------- +After 1.4.0, Behdad launched an effort to chase down excessive calls +to malloc within the implementation of cairo. He fixed a lot of +malloc-happy objects for 1.4.2, but one of the worst offenders, +(pixman regions), was left around. Mathias contributed an excellent +series of 15 patches to finish off this effort. + +The end result is a cairo that calls malloc much less often than it +did before. Compared to 1.4.2, 55% of the calls to malloc have been +eliminate, (and 60% have been eliminated compared to 1.4.0). Well +done, Mathias! + +Other improvements since 1.4.2 +------------------------------ +• Centralize mutex declarations (will reduce future build breaks), + (Mathias Hasselmann) + +• Reduce malloc by caching recently freed pattern objects (Chris + Wilson) + +• Fix some broken composite operations (David Reveman) + https://bugs.freedesktop.org/show_bug.cgi?id=5777 + +Backend-specific fixes +---------------------- +PDF: + • Use TJ operator for more compact representation of glyphs (Adrian + Johnson) + + • Fix glyph positioning bug when glyphs are not horizontal + http://lists.freedesktop.org/archives/cairo/2007-April/010337.html + +win32: + • Fix crash when rendering with bitmap fonts (Carl Worth) + https://bugzilla.mozilla.org/show_bug.cgi?id=376498 + +xlib: + • Turn metrics-hinting on by default (Behdad Esfahbod) + + • Fix edge-effect problem with transformed images drawn to xlib + (Behdad Esfahbod) + https://bugs.freedesktop.org/show_bug.cgi?id=10508 + + • Avoid dereferencing a NULL screen.

It +comes just less than 2 weeks after 1.4.0. We hadn't anticipated an +update this early, but we've managed to collect some important fixes +that we wanted to get out to cairo users as soon as possible, (6 fixes +for crashes, 1 case where graphical elements would not be drawn at +all, a handful of backend-specific bugs, and several important build +fixes). + +There's almost nothing but bug fixes in this release, (see below one +optimization that Behdad did sneak in), so we recommend that everyone +upgrade to this release when possible. + +Thanks to the many people that worked to fix these bugs, and those +that did the work to report them and to test the fixes, (wherever +possible both names are credited below). + +Critical fixes +-------------- +• Fix a crash due to a LOCK vs. UNLOCK typo (M. Drochner fixing Carl + Worth's embarrassing typo). + + http://bugs.freedesktop.org/show_bug.cgi?id=10235 + +• Fix potential buffer overflow, which on some systems with a checking + variant of snprintf would lead to a crash (Adrian Johnson, Stanislav + Brabec, and sangu). + + https://bugs.freedesktop.org/show_bug.cgi?id=10267 + https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=232576 + +• Fix a crash in cairo_stroke_extents or cairo_in_stroke when line + width is 0.0. (Carl Worth and Sebastien Bacher) + + https://bugs.freedesktop.org/show_bug.cgi?id=10231 + +• Fix a crash on certain combinations of X server/video drivers (Carl + Worth and Tomas Carnecky). + + https://bugs.freedesktop.org/show_bug.cgi?id=10250 + +• Fix a crash due to mishandling of invalid user input (Carl Worth and + Alexander Darovsky). + + https://bugs.freedesktop.org/show_bug.cgi?id=9844 + +• xlib: Cleanup server-side glyph caches on XCloseDisplay. This + eliminated a crash detected by the perf suite, (and that + applications could have run into as well). (Chris Wilson) + +Other bug fixes +--------------- +• Fix for some geometry which simply disappeared under some + transformations---a stroked line with an extreme skew in X, for + example (Carl Worth and Jonathan Watt). + + https://bugzilla.mozilla.org/show_bug.cgi?id=373632 + +• SVG: Fix radial gradients for CAIRO_EXTEND_REFLECT and when r0 > r1 + (Emmanuel Pacaud). + +• PDF: Set page group color space to DeviceRGB. + + This fixes incorrect (muddy) transparent colors when rendering cairo + PDF output in some viewers. (Adrian Johnson, Adam Goode, and + MenTaLguY). + + http://lists.freedesktop.org/archives/cairo/2006-November/008551.html + +• win32: Return correct metrics when hinting is off, and fix font + descent computation (Behdad Esfahbod). + +• quartz: Fix glyph interfaces to correctly return user-space rather + than device-space coordinates (Brian Ewins). + + https://bugs.freedesktop.org/show_bug.cgi?id=9568 + +• xcb: Fix parameter-order confusion with xcb_create_pixmap, which now + makes all tests that pass with xlib now pass with xcb (Carl Worth, + Jamey Sharp). + +• Fix some memory leaks in the perf suite (Chris Wilson). + +• Fix perf suite to consider changes in pixman/src (Mathias + Hasselmann). + +Build fixes +----------- +• Don't include pre-generated cairo-features.h file. This was causing + build failures when building with the directfb backend enabled + (Behdad Esfahbod). + + https://bugs.freedesktop.org/show_bug.cgi?id=10189 + +• Eliminate use of maintainer mode from cairo's automake/configure + script. This means that updates to files such as Makefile.am will + take effect, (by rerunning automake and friends as necessary) when + invoking make rather than being silently ignored. (Behdad Esfahbod) + +• Don't compile cairo-deflate-stream.c, which depends on zlib, unless + building the pdf backend which requires it. (Carl Worth, Tor + Lillqvist) + + https://bugs.freedesktop.org/show_bug.cgi?id=10202 + +• Don't make the ps backend link against zlib anymore, since it + doesn't require it (Carl Worth). + +• Use "find !" rather than "find -not" for better portability (Thomas + Klausner). + + https://bugs.freedesktop.org/show_bug.cgi?id=10226 + +• Don't use unsupported visibility attribute "hidden" on Solaris + (Gilles Dauphin, Thomas Klausner). + + https://bugs.freedesktop.org/show_bug.cgi?id=10227 + +Optimization +------------ +• It was Behdad that suggested we focus strictly on bug fixes now that + we shipped so many performance improvements in 1.4.0, but it was + also Behdad that got distracted by the chance to remove a lot of + mallocs from cairo. Paths, gstates, trapezoids, splines, polygons, + and gradient color stops will now use small, stack-allocated buffers + in the most common cases rather than calling malloc as + often. (Behdad Esfahbod). And look for more from Mathias Hasselmann + soon. + +Release 1.4.0 (2007-03-06 Carl Worth <cworth@cworth.org>) +========================================================= +The many people[*] who have been working hard on cairo are very +pleased to announce the long-awaited release of cairo 1.4. This +release comes 4 months after the last stable update release (1.2.6) +and 9 months since the initial release of 1.2.0. + +The release notes below are intended to capture the highlights of the +changes that have occurred from the 1.2 series to the new 1.4.0 +release. + +Performance improvements +------------------------ +Within the cairo project, the last 6 months or so has seen an intense +effort focusing on the performance of cairo itself. That effort has +paid off considerably, as can be seen in the following highlights of +some of the performance differences from cairo 1.2.6 to cairo 1.4.0. + +(Note: The performance results reported here were measured on an x86 +laptop. Many of the improvements in 1.4---particular those involving +text rendering---are even more dramatic on embedded platforms without +hardware floating-point units. Such devices played an important part +of many of the optimizations that found their way into cairo over the +last few months.) + +• Dramatic improvement when drawing objects that are mostly off-screen + with the image backend (with the xlib backend this case is still + slow due to an X server bug): + + image-rgba long-lines-uncropped-100 479.64 -> 4.98: 96.24x speedup + ███████████████████████████████████████████████▋ + +• Dramatic improvement when copying a small fraction of an image + surface to an xlib surface: + + xlib-rgba subimage_copy-512 3.93 -> 0.07: 54.52x speedup + ██████████████████████████▊ + +• Dramatic improvement to tessellation speed for complex objects: + + image-rgb tessellate-256-100 874.16 -> 34.79: 25.13x speedup + ████████████■+ xlib-rgba zrusin_another_fill-415 148.40 -> 13.85: 10.72x speedup + ████▉ + xlib-rgb world_map-800 680.20 -> 345.54: 1.97x speedup + ▌ + +• Dramatic improvement to the speed of stroking rectilinear shapes, + (such as the outline of a rectangle or "box"): + + image-rgb box-outline-stroke-100 0.18 -> 0.01: 24.22x speedup + ███████████▋ + xlib-rgb box-outline-stroke-100 0.46 -> 0.06: 8.05x speedup + ███▌ + + +• Dramatic improvements to text rendering speeds: + + xlib-rgba text_image_rgba_over-256 63.12 -> 9.61: 6.57x speedup + ██▊ + +• 3x improvements to floating-point to fixed-point conversion speeds: + + image-rgba pattern_create_radial-16 9.29 -> 3.44: 2.70x speedup + ▉ + +• 2x improvements to linear gradient computation: + + image-rgb paint_linear_rgb_source-512 26.22 -> 11.61: 2.26x speedup + ▋ + +• 2x improvement to a case common in PDF rendering: + + image-rgb unaligned_clip-100 0.10 -> 0.06: 1.81x speedup + ■+ +• 1.3x improvement to rectangle filling speed (note: this improvement + is new since 1.3.16---previously this test case was a 1.3x slowdown + compared to 1.2.6): + + image-rgba rectangles-512 6.19 -> 4.37: 1.42x speedup + ▎ + xlib-rgba rectangles-512 7.48 -> 5.58: 1.34x speedup + ■+ +NOTE: In spite of our best efforts, there are some measurable +performance regressions in 1.4 compared to 1.2. It appears that the +primary problem is the increased overhead of the new tessellator when +drawing many, very simple shapes. The following test cases capture +some of that slowdown: + + image-rgba mosaic_tessellate_lines-800 11.03 -> 14.29: 1.30x slowdown + ■+ image-rgba box-outline-fill-100 0.01 -> 0.01: 1.26x slowdown + ■+ image-rgba fill_solid_rgb_over-64 0.20 -> 0.22: 1.12x slowdown + + image-rgba fill_image_rgba_over-64 0.23 -> 0.25: 1.10x slowdown + + xlib-rgb paint_image_rgba_source-256 3.24 -> 3.47: 1.07x slowdown + +We did put some special effort into eliminating this slowdown for the +very common case of drawing axis-aligned rectangles with an identity +matrix (see the box-outline-stroke and rectangles speedup numbers +above). Eliminating the rest of this slowdown will be a worthwhile +project going forward. + +Also note that the "box-outline-fill" case is a slowdown while +"box-outline-stroke" is a (huge) speedup. These two test cases +resulted from the fact that some GTK+ theme authors were filling +between two rectangles to avoid slow performance from the more natural +means of achieving the same shape by stroking a single rectangle. With +1.4 that workaround should definitely be eliminated as it will now +cause things to perform more slowly. + +Greatly improved PDF output +--------------------------- +We are very happy to be able to announce that cairo-generated PDF +output will now have text that can be selected, cut-and-pasted, and +searched with most capable PDF viewer applications. This is something +that was not ever possible with cairo 1.2. + +Also, the PDF output now has much more compact encoding of text than +before. Cairo is now much more careful to not embed multiple copies of +the same font at different sizes. It also compresses text and font +streams within the PDF output. + +API additions +------------- +There are several new functions available in 1.4 that were not +available in 1.2. Curiously, almost all of the new functions simply +allow the user to query state that has been set in cairo (many new +"get" functions) rather than providing any fundamentally new +operations.

The XCB backend has been updated to track the latest XCB +API (which recently had a 1.0 release). + +We hope to see these backends become supported in a future release, +(once they are passing all the tests in cairo's test suite). + +The experimental OS/2 backend is new in cairo 1.4 compared to cairo +1.2. + +Documentation improvements +-------------------------- +We have added documentation for several functions and types that +were previously undocumented, and improved documentation on other +ones. As of this release, there remain only two undocumented +symbols: cairo_filter_t and cairo_operator_t. + +[*]Thanks to everyone +--------------------- +I've accounted for 41 distinct people with attributed code added to +cairo between 1.2.6 and 1.4.0, (their names are below). That's an +impressive number, but there are certainly dozens more that +contributed with testing, suggestions, clarifying questions, and +encouragement. I'm grateful for the friendships that have developed as +we have worked on cairo together. Thanks to everyone for making this +all so much fun! + +Adrian Johnson, Alfred Peng, Alp Toker, Behdad Esfahbod, +Benjamin Otte, Brian Ewins, Carl Worth, Christian Biesinger, +Christopher (Monty) Montgomery, Daniel Amelang, Dan Williams, +Dave Yeo, David Turner, Emmanuel Pacaud, Eugeniy Meshcheryakov, +Frederic Crozat, Hans Breuer, Ian Osgood, Jamey Sharp, Jeff Muizelaar, +Jeff Smith, Jinghua Luo, Jonathan Watt, Joonas Pihlaja, Jorn Baayen, +Kalle Vahlman, Kjartan Maraas, Kristian Høgsberg, M Joonas Pihlaja, +Mathias Hasselmann, Mathieu Lacage, Michael Emmel, Nicholas Miell, +Pavel Roskin, Peter Weilbacher, Robert O'Callahan, +Soren Sandmann Pedersen, Stuart Parmenter, T Rowley, +Vladimir Vukicevic + +Snapshot 1.3.16 (2007-03-02 Carl Worth <cworth@cworth.org>) +=========================================================== +New API functions +----------------- +A few new public functions have been added to the cairo API since the +1.3.14 snapshot. These include a function to query the current scaled +font: + + cairo_get_scaled_font + +New functions to query the reference count of all cairo objects: + + cairo_get_reference_count + + cairo_surface_get_reference_count + cairo_pattern_get_reference_count + + cairo_font_face_get_reference_count + cairo_scaled_font_get_reference_count + +And new functions to allow the use of user_data with any cairo object, +(previously these were only available on cairo_surface_t and +cairo_font_face_t objects): + + cairo_set_user_data + cairo_get_user_data + + cairo_pattern_set_user_data + cairo_pattern_get_user_data + + cairo_scaled_font_set_user_data + cairo_scaled_font_get_user_data + +Usability improvement for PDF/PS/SVG generation +----------------------------------------------- +In previous versions of cairo, generating single-page output with the +cairo-pdf, cairo-ps, or cairo-svg backends required a final call to +cairo_show_page. This was often quite confusing as people would port +functional code from a non-paginated backend and be totally mystified +as to why the output was blank until they learned to add this call. + +Now that call to cairo_show_page is optional, (it will be generated +implicitly if the user does not call it). So cairo_show_page is only +needed to explicitly separate multiple pages. + +Greatly improved PDF output +--------------------------- +We are very happy to be able to announce that cairo-generated PDF +output will now have text that can be selected, cut-and-paste, and +searched with most capable PDF viewer applications. This is something +that was not ever possible with cairo 1.2. + +Also, the PDF output now has much more compact encoding of text than +before. Cairo is now much more careful to not embed multiple copies of +the same font at different sizes. It also compresses text and font +streams within the PDF output. + +Major bug fixes +--------------- + • Fixed radial gradients + + The rendering of radial gradients has been greatly improved. In + the cairo 1.2 series, there was a serious regression affecting + radial gradients---results would be very incorrect unless one of + the gradient circles had a radius of 0.0 and a center point within + the other circle. These bugs have now been fixed. + + • Fixed dashing + + Several fixes have been made to the implementation of dashed + stroking. Previously, some dashed, stroked rectangles would + mis-render and fill half of the rectangle with a large triangular + shape. This bug has now been fixed. + + • Fixed transformed images in PDF/PS output + + In previous versions of cairo, painting with an image-based source + surface pattern to the PDF or PS backends would cause many kinds + of incorrect results. One of the most common problems was that an + image would be repeated many times even when the user had + explicitly requested no repetition with CAIRO_EXTEND_NONE. These + bugs have now been fixed. + + • Eliminate errors from CAIRO_EXTEND_REFLECT and CAIRO_EXTEND_PAD + + In the 1.2 version of cairo any use of CAIRO_EXTEND_REFLECT or + CAIRO_EXTEND_PAD with a surface-based pattern resulted in an + error, (cairo would stop rendering). This bug has now been + fixed. + + Now, CAIRO_EXTEND_REFLECT should work properly with surface + patterns. + + CAIRO_EXTEND_PAD is still not working correctly, but it will now + simply behave as CAIRO_EXTEND_NONE rather than triggering the + error. + +New rewrite of quartz backend (still experimental) +-------------------------------------------------- +Cairo's quartz backend has been entirely rewritten and is now much +more efficient. This backend is still marked as experimental, not +supported, but it is now much closer to becoming an officially +supported backend. (For people that used the experimental nquartz +backend in previous snapshots, that implementation has now been +renamed from "nquartz" to "quartz" and has replaced the old quartz +backend.) + +Documentation improvements +-------------------------- +We have added documentation for several functions and types that +were previously undocumented, and improved documentation on other +ones. As of this release, there remain only two undocumented +symbols: cairo_filter_t and cairo_operator_t. + +Other bug fixes +--------------- + • cairo-svg: Fix bug that was preventing text from appearing in many + viewers + + • cairo-ft: Return correct metrics when hinting is off + + • Cairo 1.3.14 deadlocks in cairo_scaled_font_glyph_extents or + _cairo_ft_unscaled_font_lock_face + + https://bugs.freedesktop.org/show_bug.cgi?id=10035 + + • cairo crashes in cairo_create_similar if nil surface returned by + other->backend->create_similar + + https://bugs.freedesktop.org/show_bug.cgi?id=9844 + + • evolution crash in _cairo_gstate_backend_to_user() + https://bugs.freedesktop.org/show_bug.cgi?id=9906 + + • Fix memory leak in rectilinear stroking code + +Things not in this release +-------------------------- + • Solid-surface-pattern cache: This patch had been applied during + the 1.3.x series, but it was reverted due to some inter-thread + problems it caused. The patch is interesting since it made a big + benefit for text rendering performance---so we'll work to bring a + corrected version of this patch back as soon as possible. + +Snapshot 1.3.14 (2006-02-13 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the seventh development snapshot in the 1.3 series, (and there +likely won't be many more before the 1.4.0 release). It comes just +over 3 weeks after the 1.3.12 snapshot. + +Since we're so close to the 1.4.0 release, there are not a lot of new +features nor even a lot of new performance improvements in this +snapshot. Instead, there are a great number of bug fixes. Some are +long-standing bugs that we're glad to say goodbye to, and several are +fixes for regressions that were introduced as part of the optimization +efforts during the 1.3.x series. + +PDF text selection fixed +------------------------ +The inability to correctly select text in cairo-generated PDF has been +a defect ever since the initial support for the PDF backend in the +cairo 1.2.0 release. With the 1.3.14 snapshot, in most situations, and +with most PDF viewer applications, the PDF generated by cairo will +allow text to be correctly selected for copy-and-paste, (as well as +searching). + +We're very excited about this new functionality, (and very grateful to +Adrian Johnson, Behdad Esfahbod, and others that have put a lot of +work into this lately). Please test this new ability and give feedback +on the cairo@cairographics.org list. + +Many thread-safety issues fixed +------------------------------- +We've discovered that no release of cairo has ever provided safe text +rendering from a multi-threaded application. With the 1.3.14 snapshot +a huge number of the bugs in this area have been fixed, and multiple +application dvelopers have now reported success at writing +multi-threaded applications with cairo. + +Other fixes +----------- +Fixed a bug that was causing glyph spacing to be 32 times larger than +desired when using cairo-win32. + +Fixed a regression in the rendering of linear gradients that had been +present since the 1.3.8 snapshot. + +Fixed several problems in cairo-atsui that were leading to assertion +failures when rendering text. + +Fix corrupted results when rendering a transformed source image +surface to an xlib surface. This was a regression that had been +present since the 1.3.2 snapshot. + +Fixed PDF output to prevent problems printing from some versions of +Acrobat Reader, (a single glyph was being substituted for every +glyph). + +And many other fixes as well, (see the logs for details). + +Snapshot 1.3.12 (2007-01-20 Carl Worth <cworth@cworth.org>) +=========================================================== +The relentless march toward the cairo 1.4 release continues, (even if +slightly late out of the starting blocks in 2007). This is the sixth +development snapshot in the 1.3 series. It comes 4 weeks after the +1.3.10 snapshot. + +Performance +----------- +As usual, this snapshot has some fun performance improvements to show +off: + +image-rgba long-lines-uncropped-100 470.08 -> 4.95: 94.91x speedup +███████████████████████████████████████████████ +image-rgb long-lines-uncropped-100 461.60 -> 4.96: 93.02x speedup +██████████████████████████████████████████████ + +This 100x improvement, (and yes, that's 100x, not 100%), in the image +backend occurs when drawing large shapes where only a fraction of the +shape actually appears in the final result, (the rest being outside +the bounds of the destination surface). Many applications should see +speedups here, and the actual amount of speedup depends on the ratio +of non-visible to visible portions of geometry. + +[Note: There remains a similar performance bug when drawing mostly +non-visible objects with the xlib backend. This is due to a similar +bug in the X server itself, but we hope a future cairo snapshot will +workaround that bug to get a similar speedup with the xlib backend.] + +image-rgba unaligned_clip-100 0.09 -> 0.06: 1.67x speedup +■+image-rgb unaligned_clip-100 0.09 -> 0.06: 1.66x speedup +■+ +This speedup is due to further MMX optimization by Soeren Sandmann for +a case commonly hit when rendering PDF files, (and thanks to Jeff +Muizelaar for writing code to extract the test case for us). + +There's another MMX optimization in this snapshot (without a fancy +speedup chart) by Dan Williams which improves compositing performance +specifically for the OLPC machine. + +Thanks to Adrian Johnson, cairo's PDF output is now much more +efficient in the way it encodes text output. By reducing redundant +information and adding compression to text output streams, Adrian +achieved a ~25x improvement in the efficiency of encoding text in PDF +files, (was ~45 bytes per glyph and is now ~1.6 bytes per glyph). + +Bug fixes +--------- +In addition to those performance improvements, this snapshot includes +several bug fixes: + + * A huge number of bug fixes for cairo-atsui text rendering, (for mac + OS X). These bugs affect font selection, glyph positioning, glyph + rendering, etc. One noteworthy bug fixes is that + cairo_select_font_face will no longer arbitrarily select bold nor + italic when not requested, (at least not when using a standard CSS2 + font family name such as "serif", "sans-serif", "monospace", etc.). + All these fixes are thanks to Brian Ewins who continues to do a + great job as the new cairo-atsui maintainer. + + * Fix PDF output so that images that are scaled down no longer + mysteriously repeat (Carl Worth). + + * Fix segfault on Mac OS X dues to attempt to measure extents of a + zero-length string (Behdad Esfahbod). + + * Fix text extents to not include the size of initial/trailing + non-inked characters (Behdad Esfahbod). + +API tweaks +---------- +Three functions have had API changes to improve consistency. Note that +the API functions being changed here are all functions that were +introduced as new functions during these 1.3.x snapshots. As always, +there will not be any API changes to functions included in a major +release (1.2.x, 1.4.x, etc.) of cairo. + +The changes are as follows: + + * Rename of cairo_copy_clip_rectangles to cairo_copy_clip_rectangle_list. + + * Change cairo_get_dash_count to return an int rather than accepting a + pointer to an int for the return value. + + * Change cairo_get_dash to have a void return type rather than + returning cairo_status_t. + +It's possible there will be one more round of changes to these +functions, (and perhaps cairo_get_color_stop as well), as we seek to +establish a unifying convention for returning lists of values. + +Snapshot 1.3.10 (2006-12-23 Carl Worth <cworth@cworth.org>) +=========================================================== +Santa Claus is coming just a little bit early this year, and he's +bringing a shiny new cairo snapshot for all the good little boys and +girls to play with. + +This is the fifth development snapshot in the 1.3 series. It comes 9 +days after the 1.3.8 snapshot, and still well within our goal of +having a new snapshot every week, (though don't expect one next +week---we'll all be too stuffed with sugar plums). + +Speaking of sugar plums, there's a sweet treat waiting in this cairo +snapshot---greatly improved performance for stroking rectilinear +shapes, like the ever common rectangle: + +image-rgb box-outline-stroke-100 0.18 -> 0.01: 25.58x speedup +████████████████████████▋ +image-rgba box-outline-stroke-100 0.18 -> 0.01: 25.57x speedup +████████████████████████▋ +xlib-rgb box-outline-stroke-100 0.49 -> 0.06: 8.67x speedup +███████▋ +xlib-rgba box-outline-stroke-100 0.22 -> 0.04: 5.39x speedup +████■+ +In past releases of cairo, some people had noticed that using +cairo_stroke to draw rectilinear shapes could be awfully slow. Many +people had worked around this by using cairo_fill with a more complex +path and gotten a 5-15x performance benefit from that. + +If you're one of those people, please rip that workaround out, as now +the more natural use of cairo_stroke should be 1.2-2x faster than the +unnatural use of cairo_fill. + +And if you hadn't ever implemented that workaround, then you just +might get to see your stroked rectangles now get drawn 5-25x faster. + +Beyond that performance fix, there are a handful of bug fixes in this +snapshot: + + * Fix for glyph cache race condition in glitz backend (Jinghua Luo) + + * Many fixes for ATSUI text rendering (Brian Ewins) + + * Un-break recent optimization-triggered regression in rendering text + with a translation in the font matrix (Behdad Esfahbod) + + * Fix make check to work on OPD platforms (IA64 or PPC64) + (Frederic Crozat) + + * Fix a couple of character spacing issues on Windows + (Jonathan Watt) + +Have fun with that, everybody, and we'll be back for more in the new +year, (with a plan to add the last of our performance improvements in +this round, fix a few bad, lingering bugs, and then finish off a nice, +stable 1.4 release before the end of January). + +-Carl + +Snapshot 1.3.8 (2006-12-14 Carl Worth <cworth@cworth.org>) +========================================================== +This is the fourth development snapshot in the 1.3 series. It comes +just slightly more than one week after the 1.3.6 snapshot. + +After the bug fixes in 1.3.6, we're back to our original program of +weekly snapshots, each one faster than the one from the week +before. Cairo 1.3.8 brings a 2x improvement in the speed of rendering +linear gradients (thanks to David Turner), and a significant reduction +in X traffic when rendering text (thanks to Xan Lopez and Behdad +Esfahbod), making cairo behave very much like Xft does. + +A few other things in the 1.3.8 snapshot worth noting include a more +forgiving image comparator in the test suite, (using the "perceptual +diff" metric and GPL implementation by Hector Yee[*]), a bug fix for +broken linking on x86_64 (thanks to M Joonas Pihlaja) and an even +better implementation of _cairo_lround, (not faster, but supporting a +more complete input range), from Daniel Amelang. + +[*] http://pdiff.sourceforge.net/ + +Snapshot 1.3.6 (2006-12-06 Carl Worth <cworth@cworth.org>) +========================================================== +This is the third development snapshot in the 1.3 series. It comes two +weeks after the 1.3.4 snapshot. + +We don't have fancy performance charts this week as the primary +changes in this snapshot are bug fixes. The performance work continues +and the next snapshot (planned for one week from today) should include +several improvements. The bug fixes in this snapshot include: + + * Fix undesirable rounding in glyph positioning (Dan Amelang) + + This bug was noticed by several users, most commonly by seeing + improper text spacing or scrambled glyphs as drawn by nautilus. For + example: + + Update to cairo-1.3.4 worsen font rendering + https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=217819 + + * Fix reduced range of valid input coordinates to tessellator + (M Joonas Pihlaja) + + This bug was causing lots of assertion failures in mozilla as + mentioned here: + + CAIRO_BO_GUARD_BITS and coordinate space? + http://lists.freedesktop.org/archives/cairo/2006-December/008743.html + + * Fix several regressions in new tessellator (M Joonas Pihlaja) + + Joonas just had a good eye for detail here. I don't think any + external cairo users had noticed any of these bugs yet. + + * Fix compilation problems of cairo "wideint" code on some platforms + (Mathieu Lacage) + + * Fix failed configure due to broken grep (Dan Amelang) + + This bug was reported here: + + AX_C_FLOAT_WORDS_BIGENDIAN doesn't work because grep doesn't + work with binary file + https://bugs.freedesktop.org/show_bug.cgi?id=9124 + + * Remove the pkg-config minimum version requirement (Behdad Esfahbod) + + Some systems ship with pkg-config 0.15 and there was really no good + reason for cairo to insist on having version 0.19 before it would + build. + +There is also one new (but inert) feature in this snapshot. There's a +new option that can be passed to cairo's configure script: + + --disable-some-floating-point + + Disable certain code paths that rely heavily on double precision + floating-point calculation. This option can improve + performance on systems without a double precision floating-point + unit, but might degrade performance on those that do. + +As of this snapshot, this option does not make any change to cairo, +but it is possible that future versions of cairo will respect this +option and change the implementation of various functions as +appropriate. + +Snapshot 1.3.4 (2006-11-22 Carl Worth <cworth@cworth.org>) +========================================================== +This is the second development snapshot in the 1.3 series. It comes +one week after the 1.3.2 snapshot. + +This snapshot has a couple of significant performance improvements, +and also adds new support for producing multi-page SVG output, (when +targeting SVG 1.2)---thanks to Emmanuel Pacaud. The details of the +performance improvements are as follows: + +1. The long-awaited "new tessellator". + + The credit for this being an improvement goes to Joonas Pihlaja. He + took my really slow code and really put it through its paces to get + the dramatic performance improvement seen below (up to 38x faster + on realistic cases, and more than 10x faster for the zrusin_another + test). + + His own writeup of the work he did is quite thorough, but more than + can be quoted here. Please see his post for the interesting details: + + http://lists.freedesktop.org/archives/cairo/2006-November/008483.html + + (Though note that this snapshot also includes some additional, + significant improvements that were only sketched out in that + email---see "Generating fewer trapezoids"). + +2. More floating-point improvements + + Daniel Amelang continues to work the magic he began in the 1.3.2 + snapshot.

But more importantly, it contains some new +API in preparation for a future 1.4 release, and most importantly, it +contains several performance improvements. + +The bug fixes will not be reviewed here, as most of them are already +described in the 1.2.6 release notes. But details for the new API and +some performance improvements are included here. + +As with all snapshots, this is experimental code, and the new API +added here is still experimental and is not guaranteed to appear +unchanged in any future release of cairo. + +API additions +------------- +Several new API additions are available in this release. There is a +common theme among all the additions in that they allow cairo to +advertise information about its state that it was refusing to +volunteer earlier. So this isn't groundbreaking new functionality, but +it is essential for easily achieving several tasks. + +The new functions can be divided into three categories: + + Getting information about the current clip region + ------------------------------------------------- + cairo_clip_extents + cairo_copy_clip_rectangles + cairo_rectangle_list_destroy + + Getting information about the current dash setting + -------------------------------------------------- + cairo_get_dash_count + cairo_get_dash + + Getting information from a pattern + ---------------------------------- + cairo_pattern_get_rgba + cairo_pattern_get_surface + cairo_pattern_get_color_stop_rgba + cairo_pattern_get_color_stop_count + cairo_pattern_get_linear_points + cairo_pattern_get_radial_circles + +In each of these areas, we have new API for providing a list of +uniform values from cairo. The closest thing we had to this before was +cairo_copy_path, (which is rather unique in providing a list of +non-uniform data). + +The copy_clip_rectangles/rectangle_list_destroy functions follow a +style similar to that of cairo_copy_path. Meanwhile, the dash and +pattern color stop functions introduce a new style in which there is a +single call to return the number of elements available (get_dash_count +and get_color_stop_count) and then a function to be called once to get +each element (get_dash and get_color_stop_rgba). + +I'm interested in hearing feedback from users of these new API +functions, particularly from people writing language bindings. One +open question is whether the clip "getter" functionality should adopt +a style similar to that of the new dash and color_stop interfaces. + +API deprecation +--------------- +The CAIRO_FORMAT_RGB16_565 enum value has been deprecated. It never +worked as a format value for cairo_image_surface_create, and it wasn't +necessary for supporting 16-bit 565 X server visuals. + +XCB backend changes +------------------- +The XCB backend has been updated to track the latest XCB API (which +recently had a 1.0 release). + +New quartz backend +------------------ +Vladimir Vukicevic has written a new "native quartz" backend which +will eventually replace the current "image-surface wrapping" quartz +backend. For now, both backends are available, (the old one is +"quartz" and the new one is "nquartz"). But it is anticipated that the +new backend will replace the old one and take on the "quartz" name +before this backend is marked as supported in a release of cairo. + +New OS/2 backend +---------------- +Doodle and Peter Weilbacher have contributed a new, experimental +backend for using cairo on OS/2 systems. + +Performance improvements +------------------------ +Here are some highlights from cairo's performance suite showing +improvements from cairo 1.2.6 to cairo 1.3.2. The command used to +generate this data is: + + ./cairo-perf-diff 1.2.6 HEAD + +available in the perf/ directory of a recent checkout of cairo's +source, (the cairo-perf-diff script does require a git checkout and +will not work from a tar file---though ./cairo-perf can still be used +to generate a single report there and ./cairo-perf-diff-files can be +used to compare two reports). + +Results are described below both for an x86 laptop (with an old Radeon +video card, recent X.org build, XAA, free software drivers), as well +as for a Nokia 770. First the x86 results with comments on each, (all +times are reported in milliseconds). + +Copying subsets of an image surface to an xlib surface (much faster) +-------------------------------------------------------------------- + xlib-rgba subimage_copy-512 10.50 -> : 53.97x speedup +█████████████████████████████████████████████████████ + +Thanks to Christopher (Monty) Montgomery for this big performance +improvement. Any application which has a large image surface and is +copying small pieces of it at a time to an xlib surface, (imagine an +application that loads a single image containing all the "sprites" for +that application), will benefit from this fix. The larger the ratio of +the image surface to the portion being copied, the larger the benefit. + +Floating-point conversion (3x faster) +------------------------------------- + xlib-rgba pattern_create_radial-16 27.75 -> 3.93 : 2.94x speedup +██ +image-rgb pattern_create_radial-16 26.06 -> 3.74 : 2.90x speedup +█▉ + +Thanks to Daniel Amelang, (and others who had contributed the idea +earlier), for this nice improvement in the speed of converting +floating-point values to fixed-point. + +Text rendering (1.3 - 2x faster) +------------------------------ + xlib-rgba text_image_rgba_source-256 319.73 -> 62.40 : 2.13x speedup +█■+image-rgb text_solid_rgba_over-64 2.85 -> 0.88 : 1.35x speedup +■+ +I don't think we've ever set out to improve text performance +specifically, but we did it a bit anyway. I believe the extra +improvement in the xlib backend is due to Monty's image copying fix +above, and the rest is due to the floating-point conversion speedup. + +Thin stroke improvements (1.5x faster) +--------------------------------------------- +image-rgb world_map-800 1641.09 -> 414.77 : 1.65x speedup +▋ + xlib-rgba world_map-800 1939.66 -> 529.94 : 1.52x speedup +▌ + +The most modest stuff to announce in this release is the 50% +improvement I made in the world_map case. This is in improvement that +should help basically anything that is doing strokes with many +straight line segments, (and the thinner the better, since that makes +tessellation dominate rasterization). The fixes here are to use a +custom quadrilateral tessellator rather than the generic tessellator +for straight line segments and the miter joins. + +Performance results from the Nokia 770 +-------------------------------------- + xlib-rgba subimage_copy-512 55.88 -> 2.04 : 27.34x speedup +██████████████████████████■+ xlib-rgb text_image_rgb_over-256 1487.58 -> 294.43 : 5.05x speedup +████ +image-rgb pattern_create_radial-16 187.13 -> 91.86 : 2.04x speedup +█ + xlib-rgba world_map-800 21261.41 -> 15628.02 : 1.36x speedup +■+ +Here we see that the subimage_copy improvement was only about half as +large as the corresponding improvement on my laptop, (27x faster +compared to 54x) and the floating-point conversion fix also was quite +as significant, (2x compared to 3x). Oddly the improvement to text +rendering performance was more than twice as good (5x compared to +2x). I don't know what the reason for that is, but I don't think it's +anything anybody should complain about. + +Release 1.2.6 (2006-11-02 Behdad Esfahbod <behdad@behdad.org>) +============================================================== +This is the third bug fix release in the 1.2 series, coming less than +two months after the 1.2.4 release made on August 18. + +The 1.2.4 release turned out to be a pretty solid one, except for a crasher +bug when forwarding an X connection where the client and the server have +varying byte orders, eg. from a PPC to an i686. Other than that, various +other small bugs have been fixed. + +Various improvements have been made in the testing infrastructure to prevent +false positives, and to make sure the generated cairo shared object behaves as +expected in terms of exported symbols and relocations. + +There were a total of 89 changes since 1.2.4. The following list the most +important ones: + +Common fixes +------------ +- Avoid unsigned loop control variable to eliminate infinite, + memory-scribbling loop. (#7593) +- Fix cairo_image_surface_create to report INVALID_FORMAT errors. + Previously the detected error was being lost and a nil surface was + returned that erroneously reported CAIRO_STATUS_NO_MEMORY. +- Change _cairo_color_compute_shorts to not rely on any particular + floating-point epsilon value. (#7497) +- Fix infinite-join test case (bug #8379) +- Pass correct surface to create_similar in _cairo_clip_init_deep_copy(). + +PS/PDF fixes +------------ +- Fix Type 1 embedding in PDF. +- Correct the value of /LastChar in the PDF Type 1 font dictionary. +- Improve error checking in TrueType subsetting. +- Compute right index when looking up left side bearing. (bug #8180) +- Correct an unsigned to signed conversion problem in truetype subsetting + bbox. +- Type1 subsetting: Don't put .notdef in Encoding when there are 256 glyphs. +- Add cairo version to PS header / PDF document info dictionary. +- Set CTM before path construction. + +Win32 fixes +----------- +- Get correct unhinted outlines on win32. (bug 7603) +- Make cairo as a win32 static library possible. +- Use CAIRO_FORMAT_RGB24 for BITSPIXEL==32 surfaces too. + +Build system fixes +------------------ +- Define WINVER if it's not defined. (bug 6456) +- Fix the AMD64 final link by removing SLIM from pixman. +- Misc win32 compilation fixes. +- Add Sun Pro C definition of pixman_private. +- Use pixman_private consistently as prefix not suffix. +- Added three tests check-plt.sh, check-def.sh, and check-header.sh that check + that the shared object, the .def file, and the public headers agree about + the exported symbols. +- Require pkg-config 0.19. (#8686) + + +Release 1.2.4 (2006-08-18 Carl Worth <cworth@cworth.org>) +========================================================= +This is the second bug fix release in the 1.2 series, coming less than +two weeks after the 1.2.2 release made on August 8. + +The big motivation for a quick release was that there were a log of +build system snags that people ran into with the 1.2.2 release. But, +by the time we got those all done, we found that we had a bunch of +fixes for cairo's rendering as well.

The 1.2.2 +release maintains source and binary compatibility with 1.2.0 and does +not make any API additions. + +Fix crashes with BGR X servers +------------------------------ +With cairo 1.2.0 many people reported problems with all cairo-using +programs, (including all GTK+ programs with GTK+ >= 2.8) immediately +crashing with a complaint about an unsupported image format. This bug +affected X servers that do not provide the Render extension and that +provide a visual with BGR rather than RGB channel order. + +report: https://bugs.freedesktop.org/show_bug.cgi?id=7294 +fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=9ae66174e774b57f16ad791452ed44efc2770a59 + +Fix the "disappearing text" bug +------------------------------- +With cairo 1.2.0 many people reported that text would disappear from +applications, sometimes reappearing with mouse motion or +selection. The text would disappear after the first space in a string +of text. This bug was caused by an underlying bug in (very common) X +servers, and only affected text rendered without antialiasing, (either +a bitmap font or a vector font with antialiasing disabled). The bug +was also exacerbated by a KDE migration bug that caused antialiasing +to be disabled more than desired. + +report: https://bugs.freedesktop.org/show_bug.cgi?id=7494 +fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=456cdb3058f3b416109a9600167cd8842300ae14 +see also: +Xorg: https://bugs.freedesktop.org/show_bug.cgi?id=7681 +KDE: http://qa.mandriva.com/show_bug.cgi?id=23990 + +Fix broken image fallback scaling (aka. "broken printing") +---------------------------------------------------------- +The various "print" backends, (pdf, ps, and svg), sometimes fallback +to using image-based rendering for some operations. In cairo 1.2.0 +these image fallbacks were scaled improperly. Applications using cairo +can influence the resolution of the image fallbacks with +cairo_surface_set_fallback_resolution. With the bug, any value other +than 72.0 would lead to incorrect results, (larger values would lead +to increasingly shrunken output). + +report: https://bugs.freedesktop.org/show_bug.cgi?id=7533 +fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=1feb4291cf7813494355459bb547eec604c54ffb + +Fix inadvertent semantic change of font matrix translation (Behdad Esfahbod) +---------------------------------------------------------------------------- +The 1.2.0 release introduced an inadvertent change to how the +translation components of a font matrix are interpreted. In the 1.0 +series, font matrix translation could be used to offset the glyph +origin, (though glyph metrics were reported incorrectly in +1.0). However in 1.2.0, the translation was applied to the advance +values between each glyph. The 1.2.0 behavior is fairly useless in +practice, and it was not intentional to introduce a semantic +change. With 1.2.2 we return to the 1.0 semantics, with a much better +implementation that provides correct glyph metrics. + +fix: http://gitweb.freedesktop.org/?p=cairo;a=commit;h=84840e6bba6e72aa88fad7a0ee929e8955ba9051 + +Fix create_similar to preserve fallback resolution and font options (Behdad Esfahbod) +------------------------------------------------------------------------------------- +There has been a long-standing issue with cairo_surface_create_similar +such that font options and other settings from the original +destination surface would not be preserved to the intermediate +"similar" surface.

Congratulations to all contributors to cairo! + +Snapshot 1.1.10 (2006-06-16 Carl Worth <cworth@cworth.org>) +=========================================================== +This is the fifth in a series of snapshots working toward the 1.2 +release of cairo. + +The primary motivation for this snapshot is to fix a long-standing bug +that had long been silent, but as of the 1.1.8 snapshot started +causing crashes when run against 16-bit depth X servers, (often Xvnc +or Xnest). The fix for this adds a new CAIRO_FORMAT_RGB16_565 to the +API. + +This snapshot also includes a rewrite of cairo's SVG backend to +eliminate the dependency on libxml2. With this in place, cairo 1.2 +will not depend on any libraries that cairo 1.0 did not. + +As usual, there are also a few fixes for minor bugs. + +Snapshot 1.1.8 (2006-06-14 Carl Worth <cworth@cworth.org>) +========================================================== +This is the fourth in a series of snapshots working toward the 1.2 +release of cairo. At this point, all major features of the 1.2 release +are in place, leaving just a few bug fixes left. + +In particular, there well be no additional API changes between this +1.1.8 snapshot and the 1.2 release. + +The announcement for 1.1.6 mentioned several API changes being +considered. Only one of these changes was actually implemented +(set_dpi -> fallback_resolution). This change does introduce one +source-level incompatibility with respect to previous 1.1.x snapshots, +so see below for details. + +Here is an abbreviated summary of changes since the 1.1.6 snapshot: + +** API Change ** +---------------- +According to the plan mentioned in the 1.1.6 notes, one source-level +incompatible change has been implemented. The following three +functions have been removed from cairo's API: + + cairo_pdf_surface_set_dpi + cairo_ps_surface_set_dpi + cairo_svg_surface_set_dpi + +and in their place the following function has been added: + + cairo_surface_set_fallback_resolution + +The signature and semantics of the function remains the same, so it is +a simple matter of changing the name of the function when calling +it. As a transition mechanism, this snapshot will (on many systems) +build to include the old symbols so that code previously compiled will +still run. However, all source code using the old names must be +updated before it will compile. And the upcoming 1.2 release is not +anticipated to include the old symbols. + +Finally, it should be pointed out that the old symbols never existed +in the supported API of any stable release of cairo. (In the stable +1.0 releases the PDF, PS, and SVG backends were advertised as +experimental and unstable.) + +And, as always, cairo continues to maintain source and binary +compatibility between major releases. So applications compiled against +supported backends in a stable release of cairo (1.0.4 say) will +continue to compile and run without modification against new major +releases (1.2.0 say) without modification. + +API additions +------------- +The following new functions have been added to cairo's API: + + cairo_surface_get_content + cairo_debug_reset_static_data + cairo_image_surface_get_data + cairo_image_surface_get_format + cairo_image_surface_get_stride + cairo_win32_font_face_create_for_hfont + +New, backend-specific pkg-config files +-------------------------------------- +In addition to the original cairo.pc file, cairo will also now install +a pkg-config files for each configured backend, (for example +cairo-pdf.pc, cairo-svg.pc, cairo-xlib.pc, cairo-win32.pc, etc.) this +also includes optional font backends (such as cairo-ft.pc) and the +optional png functionality (cairo-png.pc). + +These new pkg-config files should be very convenient for allowing +cairo-using code to easily check for the existing of optional +functionality in cairo without having to write complex rules to grub +through cairo header files or the compiled library looking for +symbols. + +Printing backend (PS, PDF, and SVG) +----------------------------------- +Improving the quality of the "printing" backends has been a priority +of the development between cairo 1.1.6 and cairo 1.1.8. + +The big improvement here is in the area of text output. Previously, at +best, text was output as paths without taking advantage of any font +support available in the output file format. + +Now, at the minimum text paths will be shared by using type3 fonts +(for PS and PDF---and similarly, defs for SVG). Also, if possible, +type3 and truetype fonts will be embedded in PostScript and PDF +output. There are still some known bugs with this, (for example, +selecting text in a cairo-generated PDF file with an embedded truetype +font does not work). So there will be some more changes in this area +before cairo 1.2, but do try test this feature out as it exists so +far. + +Many thanks to Kristian Høgsberg for the truetype and type1 font +embedding. + +win32 backend +------------- +Performance improvements by preferring GDI over pixman rendering when possible. +Fixes for text rendering. + +xlib backend +------------ +Fix potentially big performance bug by making xlib's create_similar +try harder to create a pixmap of a depth matching that of the screen. + +Bug fixes +--------- +Among various other fixes, the following bugs listed in bugzilla have +been fixed: + + Bug 2488: Patch to fix pixman samping location bug (#2488). + https://bugs.freedesktop.org/show_bug.cgi?id=2488 + + Bug 4196: undef MIN an MAX before defining to avoid duplicate definition + https://bugs.freedesktop.org/show_bug.cgi?id=4196 + + Bug 4723: configure.in: Fix m4 quoting when examining pkg-config version + https://bugs.freedesktop.org/show_bug.cgi?id=4723 + + Bug 4882: Flag Sun's X server has having buggy_repeat. + https://bugs.freedesktop.org/show_bug.cgi?id=4882 + + Bug 5306: test/pdf2png: Add missing include of stdio.h + https://bugs.freedesktop.org/show_bug.cgi?id=5306 + + Bug 7075: Fix make clean to remove cairo.def + https://bugs.freedesktop.org/show_bug.cgi?id=7075 + +(Many thanks to Behdad Esfahbod for helping us track down and fix many +of these.) + +Snapshot 1.1.6 (2006-05-04 Carl Worth <cworth@cworth.org>) +========================================================== +This is the third in a series of snapshots working toward the imminent +1.2 release of cairo. For a list of items still needing work on the +cairo 1.2 roadmap, please see: + + http://cairographics.org/ROADMAP + +As can be seen in that list, there are no longer any API additions +left on the roadmap. Instead, there is a feature (PDF type 3 fonts) a +performance optimization (X server gradients) and a list of bug +fixes. This gives us a fair amount of freedom to cut the 1.2 release +at almost any point by deciding to defer remaining bug fixes to +subsequent maintenance releases such as 1.2.2 and 1.2.4. + +Before we will do that, we must first be wiling to commit to all the +new API additions. As a heads-up, there are a couple of potential API +changes being considered. (Note that these are changes to new API +introduced during 1.1 so these will not introduce API +incompatibilities compared to the stable 1.0 series). The changes +being considered are: + + cairo_get_group_target: may acquire x and y offset return + parameters. May also be eliminated in favor of + cairo_get_target assuming its role + + cairo_pdf_surface_set_dpi: + cairo_ps_surface_set_dpi: + cairo_svg_surface_set_dpi: These functions may be removed in favor + of a new cairo_surface_set_fallback_resolution + +Additionally there is the possibility of a slight change in the +semantics of cairo_set_line_width. We believe the current behavior of the sequence: + + cairo_set_line_width; ... change CTM ...; cairo_stroke; + +is buggy. It is currently behaving the same as: + + ... change CTM ...; cairo_set_line_width; cairo_stroke; + +We are considering fixing this bug before 1.2 with the hope that +nobody is already relying on the buggy behavior described here. Do +shout if you suspect you might be in that position. + +The items included in this snapshot (since the 1.1.4 snapshot) are +described below. + +API additions +------------- +The long-awaited group-rendering support is now available with the +following function calls: + + cairo_push_group + cairo_push_group_with_content + cairo_pop_group + cairo_pop_group_to_source + cairo_get_group_target + +This API provides a much more convenient mechanism for doing rendering +to an intermediate surface without the need to manually create a +temporary cairo_surface_t and a temporary cairo_t and clean them up +afterwards. + +Add the following missing get function to complement +cairo_surface_set_device_offset: + + cairo_surface_get_device_offset + +PDF backend (API addition) +-------------------------- +The PDF backend now provides for per-page size changes, (similar to +what the PostScript backend got in the 1.1.4 snapshot). The new API +is: + + cairo_pdf_surface_set_size + +Xlib backend (API additions) +---------------------------- +The following functions have been added to allow the extraction of +Xlib surface: + + cairo_xlib_surface_get_display + cairo_xlib_surface_get_drawable + cairo_xlib_surface_get_screen + cairo_xlib_surface_get_visual + cairo_xlib_surface_get_depth + +XCB backend (experimental) +-------------------------- +Update backend so that it now compiles with the recent XCB 0.9 release. + +Bug fixes and memory leak cleanup +--------------------------------- +Various little things, nothing too significant though. + +Snapshot 1.1.4 (2006-05-03 Carl Worth <cworth@cworth.org>) +========================================================== +This is the second in a series of snapshots working toward the +upcoming 1.2 release of cairo. For a list of items still needing work +on the cairo 1.2 roadmap, please see: + + http://cairographics.org/ROADMAP + +The items included in this snapshot (since the 1.1.2 snapshot) are +described below. + +PostScript backend: new printing-oriented API +--------------------------------------------- +We anticipate that with cairo 1.2, toolkits will begin to use cairo +for printing on systems that use PostScript as the spool format. To +support this use case, we have added 4 new function calls that are +specific to the PostScript backend: + + cairo_ps_surface_set_size + cairo_ps_surface_dsc_comment + cairo_ps_surface_dsc_begin_setup + cairo_ps_surface_dsc_begin_page_setup + +These functions allow variation of the page size/orientation from one +page to the next in the PostScript output. They also allow the toolkit +to provide per-document and per-page printer control options in a +device-independent way, (for example, by using PPD options and +emitting them as DSC comments into the PostScript output). This should +allow toolkits to provide very fine-grained control of many options +available in printers, (media size, media type, tray selection, etc.). + +SVG backend: builds by default, version control +----------------------------------------------- +The SVG backend continues to see major improvements. It is expected +that the SVG backend will be a supported backend in the 1.2 +release. This backend will now be built by default if its dependencies +(freetype and libxml2) are met. + +Additionally, the SVG backend now has flexibility with regard to what +version of SVG it targets. It will target SVG 1.1 by default, which +will require image fallbacks for some of the "fancier" cairo +compositing operators. Or with the following new function calls: + + cairo_svg_surface_restrict_to_version + cairo_svg_get_versions + cairo_svg_version_to_string + +it can be made to target SVG 1.2 in which there is native support for +these compositing operators. + +Bug fixes +--------- +At least the following bugs have been fixed since the 1.1.2 snapshot: + +crash at XRenderAddGlyphs +https://bugs.freedesktop.org/show_bug.cgi?id=4705 + +Can't build cairo-1.1.2 on opensolaris due to " void function cannot return value" +https://bugs.freedesktop.org/show_bug.cgi?id=6792 + +Missing out-of-memory check at gfx/cairo/cairo/src/cairo-atsui-font.c:185 +https://bugzilla.mozilla.org/show_bug.cgi?id=336129 + +A couple of memory leaks. + +Snapshot 1.1.2 (2006-04-25 Carl Worth <cworth@cworth.org>) +========================================================== +This is the first in a series of snapshots working toward the upcoming +1.2 release of cairo. (Subsequent snapshot will use successive even +numbers for the third digit, 1.1.4, 1.1.6, etc.) This snapshot is +backwards-compatible with the 1.0 series---it makes a few API +additions but does not remove any API. + +PostScript and PDF backends are no longer "experimental" +-------------------------------------------------------- +The major theme of the 1.2 release is improved PostScript and PDF +backends for cairo. Unlike the 1.0 series, in the 1.2 series these +backends will not be marked as experimental and will be enabled by +default. We encourage people to test this snapshot and the PS/PDF +backends in particular as much as possible. + +The PostScript and PDF output is not yet ideal. + + * One major problem with the PostScript output is that image + fallbacks are used more often than strictly necessary, and the + image fallbacks are at a lower resolution than desired, (the + cairo_ps_surface_set_dpi call is ignored). + + * The major drawback of the current PDF backend implementation is + its text support. Every glyph is represented by a filled path in + the PDF file. The causes file sizes to be much larger and + rendering to be much slower than desired. + +It is anticipated that both of these shortcomings will see some +improvements before the final 1.2 release. + +In spite of those shortcomings, we hope that the PS and PDF backends +will yield faithful results for pretty much any cairo operations you +can throw at them. Please let us know if you are getting obviously +"different" results from the PS/PDF backends than from the image or +xlib backends. + +Other new experimental backends +------------------------------- +This snapshot includes three new backends that did not exist in the +1.0 series: + + * beos backend + + * directfb backend + + * svg backend + +These are all currently marked "experimental" and are disabled by +default. But the SVG backend in particular has seen a lot of recent +development and is very close to passing the entire cairo test +suite. It is possible that this backend will become a fully supported +backend by the time of the cairo 1.2 release. + +Public API additions +-------------------- +There have been a few new API functions added to cairo, including: + +New get_type functions for querying sub-types of object: + + cairo_surface_get_type + cairo_pattern_get_type + cairo_font_face_get_type + cairo_scaled_font_get_type + +More convenience in working with cairo_scaled_font_t with new getter +functions: + + cairo_scaled_font_get_font_face + cairo_scaled_font_get_font_matrix + cairo_scaled_font_get_ctm + cairo_scaled_font_get_font_options + +As well as a convenience function for setting a scaled font into a +cairo context: + + cairo_set_scaled_font + +and a function to allow text extents to be queried directly from a +scaled font, (without requiring a cairo_surface_t or a cairo_t): + + cairo_scaled_font_text_extents + +These new scaled font functions were motivated by the needs of the +pango library. + +Finally, a new path-construction function was added which clears the +current point in preparation for a new sub path. This makes cairo_arc +easier to use in some situations: + + cairo_new_sub_path + +Before the 1.2 release is final we do still plan a few more API +additions specifically motivated by the needs of Mozilla/Firefox. + +Optimizations and bug fixes +--------------------------- +Shortly after the 1.0 maintenance series branched off the mainline +there was a major rework of the cairo font internals. This should +provide some good performance benefits, but it's also another area +people should look at closely for potential regressions. + +There has not yet been any widespread, systematic optimization of +cairo, but various performance improvements have been made, (and some +of them are fairly significant). So if some things seem faster than +1.0 then things are good. If there are any performance regressions +compared to 1.0 then there is a real problem and we would like to hear +about that. + +There has been a huge number of bug fixes---too many to mention in +detail. Again, things should be better, and never worse compared to +1.0. Please let us know if your testing shows otherwise. + +Release 1.0.2 (2005-10-03 Carl Worth <cworth@cworth.org>) +========================================================= +For each bug number XXXX below, see: + + https://bugs.freedesktop.org/show_bug.cgi?id=XXXX + +for more details. + +General bug fixes +----------------- + * 4408 - Add support for dashing of stroked curves + (Carl Worth) + + * 4409 - Fix dashing so that each dash is capped on both ends + (Carl Worth) + + * 4414 - Prevent SIGILL failures (proper use of -mmmx and -msse flags) + (Sebastien Bacher, Billy Biggs) + + * 4299 - Fix crashes with text display in multi-threaded program + (Alexey Shabalin, Carl Worth) + + * 4401 - Do not use sincos function since it is buggy on some platforms) + (Tim Mooney, Carl Worth) + + * 4245 - Fix several bugs in the test suite exposed by amd64 systems + (Seemant Kulleen, Carl Worth) + + * 4321 - Add missing byteswapping on GetImage/PutImage + (Sjoerd Simons, Owen Taylor) + + * 4220 - Make the check for rectangular trapezoids simpler and more accurate + (Richard Stellingwerff, Owen Taylor) + + * 4260 - Add missing channel-order swapping for antialised fonts + (Barbie LeVile, Owen Taylor) + + * 4283 - Fix compilation failure with aggressive inlining (gcc -O3) + (Marco Manfredini, Owen Taylor) + + * 4208 - Fix some warnings from sparse + (Kjartan Maraas, Billy Biggs) + + * 4269 - Fix to not crash when compiled with -fomit-frame-pointer + (Ronald Wahl, Owen Taylor) + + * 4263 - Improve performance for vertical gradients + (Richard Stellingwerff, Owen Taylor) + + * 4231 + * 4298 - Accomodate gentoo and Mandriva versions in X server vendor string check + (Billy Biggs, Frederic Crozat, Owen Taylor) + +win32-specific fixes +-------------------- + * 4599 - Fix "missing wedges" on some stroked paths (win32) + (Tim Rowley, Jonathan Watt, Bertram Felgenhauer, Carl Worth, Keith Packard) + + * 4612 - Fix disappearing text if first character out of surface (win32) + (Tim Rowley) + + * 4602 - Fix shutdown of cairo from failing intermediate, size-0 bitmaps (win32) + Aka. the "white rectangles" bug from mozilla-svg testing + (Tim Rowley) + + * Various portability improvements for win32 + (Hans Breuer, Owen Taylor, Carl Worth) + + * 4593 - Fix font sizes to match user expectations (win32) + (Tor Lillqvist, Owen Taylor) + + * 3927 - Fix to report metrics of size 0 for glyph-not-available (win32) + (Hans Breuer, Owen Taylor, Tor Lillqvist) + + * Add locking primitives for win32 + (Hans Breuer) + +xlib-specific fixes +------------------- + * Fix crash from size-0 pixmap due to empty clip region (xlib) + (Radek Doulík, Carl Worth) + +Release 1.0.0 (2005-08-24 Carl Worth <cworth@cworth.org>) +========================================================= +Experimental backends +--------------------- + * The Glitz, PS, PDF, Quartz, and XCB backends have been declared + experimental, and are not part of the API guarantees that accompany + this release. They are not built by default, even when the required + libraries are available, and must be enabled explicitly with + --enable-ps, --enable-pdf, --enable-quartz or --enable-xcb. + + It is very painful for us to be pushing out a major release without + these backends enabled. There has been a tremendous amount of work + put into each one and all are quite functional to some + extent. However, each also has some limitations. And none of these + backends have been tested to the level of completeness and + correctness that we expect from cairo backends. + + We do encourage people to experiment with these backends and report + success, failure, or means of improving them. + +Operator behavior +----------------- + * Prior to 0.9.0 the SOURCE, CLEAR and a number of other operators + behaved in an inconsistent and buggy fashion and could affect areas + outside the clip mask. In 0.9.0, these six "unbounded" operators + were fixed to consistently clear areas outside the shape but within + the clip mask. This is useful behavior for an operator such as IN, + but not what was expected for SOURCE and CLEAR. So, in this release + the behavior of SOURCE and CLEAR has been changed again. They now + affect areas only within both the source and shape. We can write + the new operators as: + + SOURCE: dest' = (mask IN clip) ? source : dest + CLEAR: dest' = (mask IN clip) ? 0 : dest + +Behavior and API changes +------------------------ + * Setting the filter on a gradient pattern would change the + interpolation between color stops away from the normal linear + interpolation. This dubious behavior has been removed. + + * The CAIRO_CONTENT_VALID() and CAIRO_FORMAT_VALID() macros -- + implementation details that leaked into cairo.h -- have been moved + into an internal header. + + * The cairo_show_text function now advances the current point + according to the total advance values of the string. + +API additions +------------- + * cairo_set_dash can now detect error and can set + CAIRO_STATUS_INVALID_DASH. + +Features +-------- + * When compiled against recent versions of fontconfig and FreeType, + artificial bold fonts can now be turned on from fonts.conf using + the FC_EMBOLDEN fontconfig key. + +Optimization +------------ + * The compositing code from the 'xserver' code tree has now been + completely merged into libpixman. This includes MMX optimization of + common operations. + + * The image transformation code in libpixman has been improved and + now performs significantly faster. + +Bug fixes +--------- + * Several crashes related to corruption in the font caches have been + fixed. + + * All test cases now match pixel-for-pixel on x86 and PPC; this + required fixing bugs in the compositing, stroking, and pattern + rendering code. + + * Negative dash offsets have been fixed to work correctly. + + * The stroking of paths with mutiple subpaths has now been fixed to + apply caps to all subpaths rather than just the last one. + + * Many build fixes for better portability on various systems. + + * Lots of other bug fixes, but we're too tired to describe them in + more detail here. + +Release 0.9.2 (2005-08-13 Carl Worth <cworth@cworth.org>) +========================================================= +Release numbering +----------------- + * You will notice that this release jumped from 0.9.0 to 0.9.2. We've + decided to use an odd micro version number (eg. 0.9.1) to indicate + in-progress development between releases. As soon as 0.9.2 is + tagged, the version will be incremented in CVS to 0.9.3 where it + will stay until just before 0.9.4 is built, uploaded, and tagged. + + So, even-micro == a released version, odd-micro == something in-between. + +Libpixman dependency dropped +---------------------------- + * As of this release, the dependency on an external libpixman has + been dropped. Instead, the code from libpixman needed for cairo has + been incorporated into the cairo source tree. The motivation for + this change is that while cairo's API is stable and ready to be + maintained after the 1.0 release, libpixman's API is not, so we do + not want to expose it at this time. + + Also, the incorporation of libpixman into cairo also renames all + previously-public libpixman symbols in order to avoid any conflict + with a future release of libpixman + +API additions +------------- + * Macros and functions have been added so that the version of cairo + can be queried at either compile-time or at run-time. The version + is made available as both a human-readable string and as a single + integer: + + CAIRO_VERSION_STRING eg. "0.9.2" + CAIRO_VERSION eg. 000902 + + const char* + cairo_version_string (void); /* eg. "0.9.2" */ + + int + cairo_version (void); /* eg. 000902 */ + + A macro is provided to convert a three-part component version into + the encoded single-integer form: + + CAIRO_VERSION_ENCODE(X,Y,Z) + + For example, the CAIRO_VERSION value of 000902 is obtained as + CAIRO_VERSION_ENCODE(0,9,2). The intent is to make version + comparisons easy, either at compile-time: + + #if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(0,9,2) + ... + #endif + + Or at run-time: + + if (cairo_version() >= CAIRO_VERSION_ENCODE(0,9,2)) { /* ... */ } + +Thread safety +------------- + * This release adds pthread-based locking (when available) to make + the caches used by cairo safe for threaded programs. Some may + remember a failed experiment with this locking between the 0.5.1 + and 0.5.2 snapshots, (where even single-threaded programs that + linked with -lpthread would deadlock). We believe that that problem + has been fixed, so we are looking forward to testing and reports + from users with threaded applications. + +Bug fixes +--------- + * The XCB and Quartz backends failed to compiled in the 0.9.0 release + due to minor syntax errors. These have now been fixed. + + * Various crashes in glitz and pixman due to size 0 glyphs have been + fixed. + +Release 0.9.0 (2005-08-08 Carl Worth <cworth@cworth.org>) +========================================================= +Soname change +------------- + * In all prior snapshots, the libtool library versioning was set to + 1:0:0. As this release is intended to mark the beginning of + backwards-compatible releases, the versioning has been incremented + to 2:0:0. You will notice that the numeric extension on the + installed library filename will change similarly. + + This change will also require all cairo-using applications to be + recompiled. We recognize that this may cause some frustration since + this release is backwards-compatible with 0.6.0 and in that sense + "shouldn't" require re-compilation. However, since all historical + snapshots have used the same 1:0:0 version in spite of incompatible + API changes between them, it was essential that the upcoming 1.0 + release series have distinct library versioning. + + All future releases will use the library versioning to properly + indicate compatibility between releases. So, any application + re-compiled now to work with the 0.9.0 will not need to be + recompiled when a compatible 1.0 release of cairo is made in the + future. + +API additions +------------- + * Add new function calls to set/get the current antialiasing mode in + the graphics state: + + cairo_set_antialias + cairo_get_antialias + + This call accepts the same modes recently added for font options + (NONE or GRAY) but affects the rendering of geometry other than + text. The intent of this call is to enable more precise control of + which pixels are affected by each operation, for example to allow + for full-scene antialiasing for seam-free rendering. It is not + expected that non-antialiased rendering will perform better than + anti-aliased rendering. + + * Three new functions were added to provide support for mixed cairo- + and non-cairo drawing to the same surface: + + cairo_surface_mark_dirty + cairo_surface_mark_dirty_rectangle + cairo_surface_flush + + * The return type of the several "reference" functions was change, + (API compatibly), from void to the same type as the argument. The + affected functions are: + + cairo_font_face_reference + cairo_scaled_font_reference + cairo_pattern_reference + cairo_surface_reference + cairo_reference + + This allows a convenient way to assign and reference in a single + statement. + +Semantic changes +---------------- + * The behavior of cairo_set_source with a pattern with a non-identity + matrix was previously not well-defined. The new behavior is as + follows: + + The pattern's transformation matrix will be locked to the + user space in effect at the time of cairo_set_source(). This means + that further modifications of the CTM will not affect the source + pattern. + +cairo-win32 +----------- + * Some portability improvements, (eg. workaround for missing stdint.h). + +cairo-ft +-------- + * Updated to allow compilation with older versions of freetype. + +Bug fixes +--------- + * Fix the unbounded operators to actually produce a correct result, + (previously the results were artificially restricted to the + bounding box of whatever shape was being drawn rather than + extending out infinitely). The fixed operators are: + + CAIRO_OPERATOR_CLEAR + CAIRO_OPERATOR_SOURCE + CAIRO_OPERATOR_OUT + CAIRO_OPERATOR_IN + CAIRO_OPERATOR_DEST_IN + CAIRO_OPERATOR_DEST_ATOP + + * Fix cairo_mask and cairo_mask_surface to transform the mask by the + current transformation matrix (CTM). + + * Fix cairo_set_source to lock the CTM used to transform the pattern. + + * Workaround for X server Render bug involving repeating patterns + with a general transformation matrix. + + * cairo_get_font_face fixed to return a "nil" font face object rather + than NULL on error. + + * cairo_set_font_face fixed to not crash if given a NULL font face, + (which is the documented interface for restoring the default font + face). + + * Fix xlib glyphset caching to not try to free a NULL glyph. + +Snapshot 0.6.0 (2005-07-28 Carl Worth <cworth@cworth.org>) +========================================================== +API changes +----------- +* The prototypes of the following functions have changed: + + cairo_xlib_surface_create_with_xrender_format + cairo_xlib_surface_create_for_bitmap + + A Screen* parameter has been added to each. This allows the cairo + xlib backend to work correctly with multi-head X servers. + +* The following function has been modified: + + cairo_scaled_font_create + + to accept a cairo_font_options_t*. See below fore more details. + +* All opaque, reference-counted cairo objects have now been moved to a + standard error-handling scheme. The new objects to receive this + treatment are cairo_font_face_t, cairo_scaled_font_t, and + cairo_surface_t. (Previous snapshots already provided this scheme + for cairo_t, cairo_path_t, and cairo_pattern_t.) + + This changes two functions to have a return type of void rather than + cairo_status_t: + + cairo_scaled_font_extent + cairo_surface_finish + + And significantly, none of the create functions for any of the + objects listed above will return NULL. The pointer returned from any + function will now always be a valid pointer and should always be + passed to the corresponding destroy function when finished + + The simplest strategy for porting code is to switch from: + + object = cairo_<object>_create (); + if (object == NULL) + goto BAILOUT; + + /* act on object */ + + cairo_<object>_destroy (object); + + to: + + object = cairo_<object>_create (); + if (cairo_<object>_status (object)) + goto BAILOUT; + + /* act on object */ + + cairo_<object>_destroy (object); + + But significantly, it is not required to check for an error status + before the "act on object" portions of the code above. All + operations on an object with an error status are, by definition, + no-ops without side effect. So new code might be written in an + easier-to-read style of: + + object = cairo_<object>_create (); + + /* act on object */ + + cairo_<object>_destroy (object); + + with cairo_<object>_status checks placed only at strategic + locations. For example, passing an error object to another object, + (eg. cairo_set_source with an in-error pattern), will propagate the + error to the subsequent object (eg. the cairo_t). This means that + error checking can often be deferred even beyond the destruction of + a temporary object. + +API additions +------------- +* New functions for checking the status of objects that have been + switched to the common error-handling scheme: + + cairo_font_face_status + cairo_scaled_font_status + cairo_surface_status + +* The _cairo_error function which was added in 0.5.1 has now been made + much more useful. In 0.5.1 only errors on cairo_t objects passed + through _cairo_error. Now, an error on any object should pass + through _cairo_error making it much more reliable as a debugging + mechanism for finding when an error first occurs. + +* Added new font options support with a myriad of functions: + + cairo_font_options_create + cairo_font_options_copy + cairo_font_options_destroy + + cairo_font_options_status + + cairo_font_options_merge + cairo_font_options_equal + cairo_font_options_hash + + cairo_font_options_set_antialias + cairo_font_options_get_antialias + cairo_font_options_set_subpixel_order + cairo_font_options_get_subpixel_order + cairo_font_options_set_hint_style + cairo_font_options_get_hint_style + cairo_font_options_set_hint_metrics + cairo_font_options_get_hint_metrics + + cairo_surface_get_font_options + + cairo_ft_font_options_substitute + + cairo_set_font_options + cairo_get_font_options + + This new font options support allows the application to have much + more fine-grained control over how fonts are rendered. + Significantly, it also allows surface backends to have some + influence over the process. For example, the xlib backend now + queries existing Xft properties to set font option defaults. + +* New function: + + cairo_xlib_surface_set_drawable + + which allows the target drawable for an xlib cairo_surface_t to be + changed to another with the same format, screen, and display. This + is necessary in certain double-buffering techniques. + +New features +------------ +* Sub-pixel text antialiasing is now supported. + +Bug fixes +--------- +* Fixed assertion failure in cairo_surface_create_similar when + application commits an error by passing a cairo_format_t rather than + a cairo_content_t. + +* Avoid division by zero in various places (cairo-ft). + +* Fix infinite loop when using non-default visuals (cairo-xlib). + +* Eliminate segfault in cairo_image_surface_create_from_png_stream. + +* Prevent errant sign-extension of masks on 64-bit architectures + (cairo-xlib and cairo-xcb). + +* Other miscellaneous fixes. + +Snapshot 0.5.2 (2005-07-18 Carl Worth <cworth@cworth.org>) +========================================================== +API changes +----------- +* New functions for creating patterns of a single color: + + cairo_pattern_create_rgb + cairo_pattern_create_rgba + +* Change cairo_surface_create_similar to accept a new type of + cairo_content_t rather than cairo_format_t: + + typedef enum _cairo_content { + CAIRO_CONTENT_COLOR = 0x1000, + CAIRO_CONTENT_ALPHA = 0x2000, + CAIRO_CONTENT_COLOR_ALPHA = 0x3000 + } cairo_content_t; + +* Add new CAIRO_FORMAT_VALID and CAIRO_CONTENT_VALID macros. + +* Remove unused status value: + + CAIRO_STATUS_NO_TARGET_SURFACE + +* Add new status values: + + CAIRO_STATUS_INVALID_STATUS + +* Require libpixman >= 0.1.5 (for necessary bug fixes) + +Bug fixes +--------- +* Fix cairo_surface_write_to_png for RGB24 images. + +* Fix broken metrics and rendering for bitmap fonts. Add mostly + useless bitmap glyph transformation. + +* Fix glyph caches to not eject entries that might be immediately + needed, (fixing intermittent crashes when rendering text). + +* Fix all memory leaks found by running "make check-valgrind". + +ATSUI backend changes +--------------------- +* Allow building against < 10.3 SDK. + +* Prevent crash on empty strings. + +Glitz backend changes +--------------------- +* Require glitz >= 0.4.4. + +* Use frame buffer objects instead of pbuffers for accelerated + offscreen drawing. + +* Minor improvement to gradient pattern creation. + +PostScript backend fixes +------------------------ +* Rewrite of the PS backend to generate more interesting output that + the old big-image implementation. + +Win32 backend fixes +------------------- +* Implement glyph path support. + +* Fix swap of blue and green values in the fill_rectangles path. + +Xlib backend fixes +------------------ +* Add optimization to use XCopyArea rather than XRenderComposite when + transforming only with an integer translation, and using SOURCE + operator or OVER with a source pattern without alpha. + +Snapshot 0.5.1 (2005-06-20 Carl Worth <cworth@cworth.org>) +========================================================== +API changes +----------- +* Removed cairo_status_string(cairo_t*) and add + cairo_status_to_string(cairo_status_t) in its place. Code using + cairo_status_string can be ported forward as follows: + + cairo_status (cr); + -> + cairo_status_to_string (cairo_status (cr)); + +* Removed the BAD_NESTING restriction which means that two different + cairo_t objects can now interleave drawing to the same + cairo_surface_t without causing an error. + +* The following functions which previously had a return type of + cairo_status_t now have a return type of void: + + cairo_pattern_add_color_stop_rgba + cairo_pattern_set_matrix + cairo_pattern_get_matrix + cairo_pattern_set_extend + cairo_pattern_set_filter + + See discussion of cairo_pattern_status below for more details. + +API additions +------------- +* Improved error handling: + + cairo_status_t + cairo_pattern_status (cairo_pattern_t *pattern); + + This snapshot expands the status-based error handling scheme from + cairo_t to cairo_path_t and cairo_pattern_t. It also expands the + scheme so that object-creating functions, (cairo_create, + cairo_pattern_create_*, cairo_copy_path_*), are now guaranteed to + not return NULL. Instead, in the case of out-of-memory these + functions will return a static object with + status==CAIRO_STATUS_NO_MEMORY. The status can be checked with the + functions cairo_status and cairo_pattern_status, or by direct + inspection of the new status field in cairo_path_t. + + Please note that some objects, including cairo_surface_t and all of + the font-related objects have not been converted to this + error-handling scheme. + +* In addition to the above changes, a new private function has been added: + + _cairo_error + + This function can be used to set a breakpoint in a debugger to make + it easier to find programming error in cairo-using code. (Currently, + _cairo_error is called when any error is detected within a cairo_t + context, but is not called for non-cairo_t errors such as for + cairo_path_t and cairo_pattern_t). + +* Fixed cairo_path_data_t so that its enum is visible to C++ code, (as + cairo_path_data_type_t). + +Performance improvements +------------------------ +* Made a minor performance improvement for clipping, (restrict clip + surface to the new intersected bounds). + +* Optimize rendering of a solid source pattern with a pixel-aligned + rectangular path to use backend clipping rather than rasterization + and backend compositing. + +* Optimize cairo_paint_with_alpha to defer to cairo_paint when alpha + is 1.0. + +Bug fixes +--------- +* Fixed memory leak in cairo_copy_path. + +* A build fix for non-srcdir builds. + +PDF backend fixes +----------------- +* New support for path-based clipping. + +* Fix for text rotated to angles other than multiples of π/2. + +Win32 backend fixes +------------------- +* Fix for text extents. + +Xlib backend +------------ +* Implemented a complex workaround for X server bug[*] related to + Render-based compositing with untransformed, repeating source + pictures. The workaround uses core Xlib when possible for + performance, (ie. with CAIRO_OPERATOR_SOURCE or CAIRO_OPERATOR_OVER + with an opaque source surface), and falls back to the pixman + image-based compositing otherwise. + + [*] https://bugs.freedesktop.org/show_bug.cgi?id=3566 + +* Various bug fixes, particularly in the fallback paths. + +Snapshot 0.5.0 (2005-05-17 Carl Worth <cworth@cworth.org>) +========================================================== +This is a pretty big, and fairly significant snapshot. It represents +between 2 and 3 months of solid work from a lot of people on improving +the API as much as possible. I'd like to express my appreciation and +congratulations to everyone who has worked on the big API Shakeup, +(whether in email battles over names, or fixing my silly bugs). + +This snapshot will require some effort on the part of users, since +there are a _lot_ of API changes (ie. no cairo program ever written is +safe --- they're all broken now in at least one way). But, in spite of +that, we do encourage everyone to move their code to this snapshot as +soon as possible. And we're doing everything we can think of to make +the transition as smooth as possible. + +The idea behind 0.5 is that we've tried to make every good API change +we could want now, and get them all done with. That is, between now +and the 1.0 release of cairo, we expect very few new API changes, +(though some will certainly sneak in). We will have some significant +additions, but the pain of moving code from cairo 0.4 to cairo 0.5 +should be a one time experience, and things should be much smoother as +we continue to move toward cairo 1.0. + +And with so many changes coming out for the first time in this 0.5 +release, we really do need a lot of people trying this out to make +sure the ideas are solid before we freeze the API in preparation for +the 1.0 release. + +OK, enough introduction. Here is a (not-quite-complete) description of +the API removals, changes and additions in this snapshot, (compared to +0.4.0) + +API removals +============ +The following public functions have been removed: + +- cairo_set_target_* + + This is a big change. See the description of cairo_create in + the API changes section for how to deal with this. + +- cairo_set_alpha + + Alpha blending hasn't gone away; there's just a much more + unified rendering model now. Almost all uses of + cairo_set_alpha will be trivially replaced with + cairo_set_source_rgba and a few others will be replaced just + as easily with cairo_paint_with_alpha. + +- cairo_show_surface + + Another useful function that we realized was muddling up the + rendering model. The replacement is quite easy: + cairo_set_source_surface and cairo_paint. + +- cairo_matrix_create +- cairo_matrix_destroy +- cairo_matrix_copy +- cairo_matrix_get_affine + + These functions supported an opaque cairo_matrix_t. We now + have an exposed cairo_matrix_t structure, so these can be + dropped. + +- cairo_surface_set_repeat +- cairo_surface_set_matrix +- cairo_surface_set_filter + + These properties don't belong on surfaces. If you were using + them, you'll just want to instead use + cairo_pattern_create_for_surface and then set these properties + on the pattern. + +- cairo_copy + + This was a confusing function and hopefully nobody will miss + it. But if you really don't find cairo_save/restore adequate, + let us know and we have another idea for a potential + replacement. + +And while we're on the subject of removals, we carefully tightened up +the cairo header files so they no longer gratuitously include header +files that are not strictly necessary, (stdio.h, stdint.h, pixman.h, +Xrender.h, etc. and their dependencies). This may lead to some +surprising errors, so keep your eyes open for that. + +API changes +=========== +Here are some of the API changes that have occurred: + +~ cairo_create(void) -> cairo_create(cairo_surface_t *) + + This is the big change that breaks every program. The ability + to re-target a cairo_t was not particularly useful, but it did + introduce a lot of muddy semantic questions. To eliminate + that, cairo_create now requires its target surface to be + passed in at creation time. This isn't too hard to cope with + as the typical first operation after cairo_create was often + cairo_set_target_foo. So the order of those two swap and the + application instead has cairo_foo_surface_create, then + cairo_create. + +~ cairo_current_* -> cairo_get_* + + We had a strange mixture of cairo_get and cairo_current + functions. They've all been standardized on cairo_get, (though + note one is cairo_get_current_point). + +~ CAIRO_OPERATOR_SRC -> CAIRO_OPERATOR_SOURCE +~ CAIRO_OPERATOR_OVER_REVERSE -> CAIRO_OPERATOR_DEST_OVER + + Many of the cairo_operator_t symbolic values were renamed to + reduce the amount of abbreviation. The confusing "OP_REVERSE" + naming was also changed to use "DEST_OP" instead which is + easier to read and has wider acceptance in other + libraries/languages. + +~ cairo_set_pattern -> cairo_set_source +~ cairo_set_rgb_color -> cairo_set_source_rgb + + All of the various functions that changed the source + color/pattern were unified to use cairo_set_source names to + make the relation more clear. + +~ cairo_transform_point -> cairo_user_to_device +~ cairo_transform_distance -> cairo_user_to_device_distance +~ cairo_inverse_transform_point -> cairo_device_to_user +~ cairo_inverse_transform_distance -> cairo_device_to_user_distance + + These names just seemed a lot more clear. + +~ cairo_init_clip -> cairo_reset_clip +~ cairo_concat_matrix -> cairo_transform + + More abbreviation elimination + +~ cairo_current_path -> cairo_copy_path +~ cairo_current_path_flat -> cairo_copy_path_flat + + The former mechanism for examining the current path was a + function that required 3 or 4 callbacks. This was more + complexity than warranted in most situations. The new + cairo_copy_path function copies the current path into an + exposed data structure, and the documentation provides a + convenient idiom for navigating the path data. + +API additions +------------- ++ cairo_paint + + A generalized version of the painting operators cairo_stroke + and cairo_fill. The cairo_paint call applies the source paint + everywhere within the current clip region. Very useful for + clearing a surface to a solid color, or painting an image, + (see cairo_set_source_surface). + ++ cairo_paint_with_alpha + + Like cairo_paint but applying some alpha to the source, + (making the source paint translucent, eg. to blend an image on + top of another). + ++ cairo_mask + + A more generalized version of cairo_paint_with_alpha which + allows a pattern to specify the amount of translucence at each + point rather than using a constant value everywhere. + ++ cairo_mask_surface + + A convenience function on cairo_mask for when the mask pattern + is already contained within a surface. + ++ cairo_surface_set_user_data ++ cairo_surface_get_user_data ++ cairo_font_face_set_user_data ++ cairo_font_face_get_user_data + + Associate arbitrary data with a surface or font face for later + retrieval. Get notified when a surface or font face object is + destroyed. + ++ cairo_surface_finish + + Allows the user to instruct cairo to finish all of its + operations for a given surface. This provides a safe point for + doing things such as flushing and closing files that the + surface may have had open for writing. + ++ cairo_fill_preserve ++ cairo_stroke_preserve ++ cairo_clip_preserve + + One interesting change in cairo is that the path is no longer + part of the graphics state managed by + cairo_save/restore. This allows functions to construct paths + without interfering with the graphics state. But it prevents + the traditional idiom for fill-and-stroke: + + cairo_save; cairo_fill; cairo_restore; cairo_stroke + + Instead we know have alternate versions cairo cairo_fill, + cairo_stroke, and cairo_clip that preserve the current path + rather than consuming it. So the idiom now becomes simply: + + cairo_fill_preserve; cairo_stroke + ++ cairo_surface_write_to_png ++ cairo_surface_write_to_png_stream + + In place of a single PNG backend, now a surface created + through any backend (except PDF currently) can be written out + to a PNG image. + ++ cairo_image_surface_create_from_png ++ cairo_image_surface_create_from_png_stream + + And its just as easy to load a PNG image into a surface as well. + ++ cairo_append_path + + With the new, exposed path data structure, it's now possible + to append bulk path data to the current path, (rather than + issuing a long sequence of cairo_move_to/line_to/curve_to + function calls). + +Xlib and XCB backends +--------------------- + +Any cairo_format_t and Colormap arguments have been dropped from +cairo_xlib_surface_create. There are also two new +cairo_xlib|xcb_surface_create functions: + + cairo_xlib|xcb_surface_create_for_bitmap + (Particular for creating A1 surfaces) + cairo_xlib|xcb_surface_create_with_xrender_format + (For any other surface types, not described by a Visual*) + +All of these surface create functions now accept width and height. In +addition, there are new cairo_xlib|xcb_surface_set_size functions +which must be called each time a window that is underlying a surface +changes size. + +Print backends (PS and PDF) +--------------------------- +The old FILE* based interfaces have been eliminated. In their place we +have two different functions. One accepts a simple const char +*filename. The other is a more general function which accepts a +callback write function and a void* closure. This should allow the +flexibility needed to hook up with various stream object in many +languages. + +In addition, when specifying the surface size during construction, the +units are now device-space units (ie. points) rather than inches. This +provides consistency with all the other surface types and also makes +it much easier to reason about the size of the surface when drawing to +it with the default identity matrix. + +Finally, the DPI parameters, which are only needed to control the +quality of fallbacks, have been made optional. Nothing is required +during surface_create (300 DPI is assumed) and +cairo_ps|pdf_surface_set_dpi can be used to set alternate values if +needed. + +Font system +----------- +Owen very graciously listened to feedback after the big font rework he +had done for 0.4, and came up with way to improve it even more. In 0.4 +there was a cairo_font_t that was always pre-scaled. Now, there is an +unscaled cairo_font_face_t which is easier to construct, (eg. no +scaling matrix required) and work with, (it can be scaled and +transformed after being set on the graphics state). And the font size +manipulation functions are much easier. You can set an explicit size +and read/modify/write the font matrix with: + + cairo_set_font_size + cairo_get_font_matrix + cairo_set_font_matrix + +(Previously you could only multiply in a scale factor or a matrix.) A +pleasant side effect is that we can (and do) now have a default font +size that is reasonable, as opposed to the old default height of one +device-space unit which was useless until scaled. + +Of course, the old pre-scaled font had allowed some performance +benefits when getting many metrics for a font. Those benefits are +still made available through the new cairo_scaled_font_t. And a +cairo_font_face_t can be "promoted" to a cairo_scaled_font_t by +suppling a font_matrix and the desired CTM. + +Quartz backend +-------------- +Tim Rowley put in the work to bring the Quartz backend back after it +had been disabled in the 0.4.0 snapshot. He was not able to bring back +the function that allows one to create a cairo_font_t from an ATSUI +style: + + cairo_font_t * + cairo_atsui_font_create (ATSUStyle style); + +because he didn't have a test case for it. If you care about this +function, please provide a fairly minimal test and we'll try to bring +it back in an upcoming snapshot. + +Snapshot 0.4.0 (2005-03-08 Carl Worth <cworth@cworth.org>) +========================================================== +New documentation +----------------- +Owen Taylor has converted cairo's documentation system to gtk-doc and +has begun some long-needed work on the documentation, which can now be +viewed online here: + + http://cairographics.org/manual/ + +New backend: win32 +------------------ +This is the first snapshot to include a functional win32 backend, +(thanks to Owen Taylor). The interface is as follows: + + #include <cairo-win32.h> + + void + cairo_set_target_win32 (cairo_t *cr, + HDC hdc); + + cairo_surface_t * + cairo_win32_surface_create (HDC hdc); + + cairo_font_t * + cairo_win32_font_create_for_logfontw (LOGFONTW *logfont, + cairo_matrix_t *scale); + + cairo_status_t + cairo_win32_font_select_font (cairo_font_t *font, + HDC hdc); + + void + cairo_win32_font_done_font (cairo_font_t *font); + + double + cairo_win32_font_get_scale_factor (cairo_font_t *font); + +And see also the documentation at: + +http://cairographics.org/manual/cairo-Microsoft-Windows-Backend.html + +Disabled backend: quartz +------------------------ +Unfortunately, the quartz backend code is currently out of date with +respect to some recent backend interface changes. So, the quartz +backend is disabled in this snapshot. + +If the quartz backend is brought up-to-date before the next snapshot, +we would be glad to make a 0.4.1 snapshot that re-enables it, (we do +not expect many more big backend interface changes). + +API Changes +----------- +The font system has been revamped, (as Owen Taylor's work with +integrating pango and cairo gave us the first serious usage of the +non-toy font API). + +One fundamental, user-visible change is that the cairo_font_t object +now represents a font that is scaled to a particular device +resolution. Further changes are described below. + + cairo.h + ------- + Removed cairo_font_set_transform and cairo_font_current_transform. + + Added cairo_font_extents and cairo_font_glyph_extents. See + documentation for details: + + http://cairographics.org/manual/cairo-cairo-t.html#cairo-font-extents + + cairo-ft.h + ---------- + The cairo_ft_font API changed considerably. Please see the + documentation for details: + + http://cairographics.org/manual/cairo-FreeType-Fonts.html + +Performance +----------- +Make the fast-path clipping (pixel-aligned rectangles) faster. + +Add optimization for applying a constant alpha to a pattern. + +Optimize gradients that are horizontal or vertical in device space. + +Xlib: When RENDER is not available, use image surfaces for +intermediate surfaces rather than xlib surfaces. + +Backend-specific changes +------------------------ + Glitz + ----- + Major update to glitz backend. The output quality should now be just + as good as the image and xlib backends. + + Track changes to glitz 0.4.0. + + PDF + --- + Various improvements to produce more conformant output. + +Internals +--------- +David Reveman contributed a large re-work of the cairo_pattern_t +implementation, providing cleaner code and more optimization +opportunities. + + Backend interface changes + ------------------------- + Rework backend interface to accept patterns, not surfaces for source + and mask. + + Remove set_matrix, set_filter, and set_repeat functions. + + More sophisticated backend interface for image fallbacks, + ({acquire,release}_{source,dest}_image() and clone_similar). + +Bug fixes +--------- +Only install header files for backends that have been compiled. + +Fixed some rounding errors leading to incorrectly placed glyphs. + +Many other minor fixes. + +Snapshot 0.3.0 (2005-01-21 Carl Worth <cworth@cworth.org>) +========================================================== +Major API changes +----------------- +1) The public header files will no longer be directly installed into + the system include directory. They will now be installed in a + subdirectory named "cairo", (eg. in /usr/include/cairo rather than + in /usr/include). + + As always, the easiest way for applications to discover the + location of the header file is to let pkg-config generate the + necessary -I CFLAGS and -L/-l LDFLAGS. For example: + + cc `pkg-config --cflags --libs cairo` -o foo foo.c + + IMPORTANT: Users with old versions of cairo installed will need to + manually remove cairo.h and cairo-features.h from the + system include directories in order to prevent the old + headers from being used in preference to the new ones. + +2) The backend-specific portions of the old monolithic cairo.h have + been split out into individual public header files. The new files + are: + + cairo-atsui.h + cairo-ft.h + cairo-glitz.h + cairo-pdf.h + cairo-png.h + cairo-ps.h + cairo-quartz.h + cairo-xcb.h + cairo-xlib.h + + Applications will need to be modified to explicitly include the new + header files where appropriate. + +3) There are two new graphics backends in this snapshot, a PDF + backend, and a Quartz backend. There is also one new font backend, + ATSUI. + +PDF backend +----------- +Kristian Høgsberg has contributed a new backend to allow cairo-based +applications to generate PDF output. The interface for creating a PDF +surface is similar to that of the PS backend, as can be seen in +cairo-pdf.h: + + void + cairo_set_target_pdf (cairo_t *cr, + FILE *file, + double width_inches, + double height_inches, + double x_pixels_per_inch, + double y_pixels_per_inch); + + cairo_surface_t * + cairo_pdf_surface_create (FILE *file, + double width_inches, + double height_inches, + double x_pixels_per_inch, + double y_pixels_per_inch); + +Once a PDF surface has been created, applications can draw to it as +any other cairo surface. + +This code is still a bit rough around the edges, and does not yet +support clipping, surface patterns, or transparent gradients. Text +only works with TrueType fonts at this point and only black text is +supported. Also, the size of the generated PDF files is currently +quite big. + +Kristian is still actively developing this backend, so watch this +space for future progress. + +Quartz backend +-------------- +Calum Robinson has contributed a new backend to allow cairo +applications to target native Mac OS X windows through the Quartz +API. Geoff Norton integrated this backend into the current +configure-based build system, while Calum also provided Xcode build +support in the separate "macosx" module available in CVS. + +The new interface, available in cairo-quartz.h, is as follows: + + void + cairo_set_target_quartz_context (cairo_t *cr, + CGContextRef context, + int width, + int height); + + cairo_surface_t * + cairo_quartz_surface_create (CGContextRef context, + int width, + int height); + +There is an example program available in CVS in cairo-demo/quartz. It +is a port of Keith Packard's fdclock program originally written for +the xlib backend. A screenshot of this program running on Mac OS X is +available here: + + http://cairographics.org/~cworth/images/fdclock-quartz.png + +ATSUI font backend +------------------ +This new font backend complements the Quartz backend by allowing +applications to use native font selection on Mac OS X. The interface +is a single new function: + + cairo_font_t * + cairo_atsui_font_create (ATSUStyle style); + +Minor API changes +----------------- +Prototype for non-existent function "cairo_ft_font_destroy" removed. + +Now depends on libpixman 0.1.2 or newer, (0.1.3 is being released +concurrently and has some useful performance improvements). + +Default paint color is now opaque black, (was opaque white). Default +background color is transparent (as before). + +Renamed "struct cairo" to "struct _cairo" to free up the word "cairo" +from the C++ identifier name space. + +Functions returning multiple return values through provided pointers, +(cairo_matrix_get_affine, cairo_current_point, and +cairo_current_color_rgb), will now accept NULL for values the user +wants to ignore. + +CAIRO_HAS_FREETYPE_FONT has now been renamed to CAIRO_HAS_FT_FONT. + +Performance improvements +------------------------ +Alexander Larsson provided some fantastic performance improvements +yielding a 10000% performance improvement in his application, (when +also including his performance work in libpixman-0.1.3). These include + + * Fixed handling of cache misses. + + * Creating intermediate clip surfaces at the minimal size required. + + * Eliminating roundtrips when creating intermediate Xlib surfaces. + +Implementation +-------------- +Major re-work of font metrics system by Keith Packard. Font metrics +should now be much more reliable. + +Glitz backend +------------- +Updated for glitz-0.3.0. +Bug fixes in reference counting. + +Test suite +---------- +New tests for cache crashing, rotating text, improper filling of +complex polygons, and leaky rasterization. + +Bug fixes +--------- +Fixed assertion failure when selecting the same font multiple times in +sequence. + +Fixed reference counting so cache_destroy functions work. + +Remove unintended copyright statement from files generated with +PostScript backend. + +Fixed to eliminate new warnings from gcc 3.4 and gcc 4. + +Snapshot 0.2.0 (2004-10-27 Carl Worth <cworth@cworth.org>) +=========================================================== +New license: LGPL/MPL +--------------------- +The most significant news with this release is that the license of +cairo has changed. It is now dual-licensed under the LGPL and the +MPL. For details see the COPYING file as well as COPYING-LGPL-2.1 and +COPYING-MPL-1.1. + +I express my thanks to everyone involved in the license change process +for their patience and support! + +New font and glyph internals +---------------------------- +Graydon Hoare has put a tremendous amount of work into new internals +for handling fonts and glyphs, including caches where appropriate. +This work has no impact on the user-level API, but should result in +great performance improvements for applications using text. + +New test suite +-------------- +This snapshot of cairo includes a (small) test suite in +cairo/test. The tests can be run with "make check". The test suite was +designed to make it very easy to add new tests, and we hope to see +many contributions here. As you find bugs, please try adding a minimal +test case to the suite, and submit it with the bug report to the +cairo@cairographics.org mailing list. This will make it much easier +for us to track progress in fixing bugs. + +New name for glitz backend +-------------------------- +The gl backend has now been renamed to the glitz backend. This means +that the following names have changed: + + CAIRO_HAS_GL_SURFACE -> CAIRO_HAS_GLITZ_SURFACE + cairo_set_target_gl -> cairo_set_target_glitz + cairo_gl_surface_create -> cairo_glitz_surface_create + +This change obviously breaks backwards compatibility for applications +using the old gl backend. + +Up-to-date with latest glitz snapshots +-------------------------------------- +This snapshot of cairo is now up to date with the latest glitz +snapshot, (currently 0.2.3). We know that the latest cairo and glitz +snapshots have been incompatible for a very long time. We've finally +fixed that now and we're determined to not let that happen again. + +Revert some tessellation regression bugs +---------------------------------------- +People that have been seeing some tessellation bugs, (eg. leaked +fills), in the CVS version of cairo may have better luck with this +release. A change since the last snapshot was identified to trigger +some of these bugs and was reverted before making the snapshot. The +behavior should be the same as the previous (0.1.23) snapshot. + +Miscellaneous changes +--------------------- +Changed CAIRO_FILTER_DEFAULT to CAIRO_FILTER_BEST to make gradients +easier. + +Track XCB API change regarding iterators. + +Various bug fixes +----------------- +Fix calculation of required number of vertices for pen. + +Fix to avoid zero-dimensioned pixmaps. + +Fix broken sort of pen vertices. + +Fix bug when cairo_show_text called with a NULL string. + +Fix clipping bugs. + +Fix bug in computing image length with XCB. + +Fix infinite loop bug in cairo_arc. + +Fix memory management interactions with libpixman. + +Snapshot 0.1.23 (2004-05-11 Carl Worth <cworth@isi.edu>) +======================================================== +Fixes for gcc 3.4 +----------------- +Fix prototype mismatches so that cairo can be built by gcc 3.4. + +Updates to track glitz +---------------------- +Various fixes to support the latest glitz snapshot (0.1.2). + +Gradient updates +---------------- +Radial gradients now support both inner and outer circles. +Transformed linear gradients are now properly handled. +Fixes for extend type reflect. + +Glitz updates +------------- +Converted shading routines to use fixed point values and introduced a +shading operator structure for more efficient shading calculations. +Support compositing with mask surface when mask is solid or +multi-texturing is available. + +PNG backend cleanups +-------------------- +Fix output to properly compensate for pre-multiplied alpha format in cairo. +Add support for A8 and A1 image formats. + +Bug fixes +--------- +Avoid crash or infinite loop on null strings and degeneratively short +splines. + +New? bugs in cairo_clip +----------------------- +There are some fairly serious bugs in cairo_clip. It is sometimes +causing an incorrect result. And even when it does work, it is +sometimes so slow as to be unusable. Some of these bugs may not be +new, (indeed cairo_clip has only ever had a braindead-slow +implementation), but I think they're worth mentioning here. + +Snapshot 0.1.22 (2004-04-16 Carl Worth <cworth@isi.edu>) +======================================================== +Cairo was updated to track the changes in libpixman, and now depends +on libpixman version 0.1.1. + +Snapshot 0.1.21 (2004-04-09 David Reveman <c99drn@cs.umu.se>) +============================================================= +New OpenGL backend +------------------ +The OpenGL backend provides hardware accelerated output for +X11 and OS X. The significant new functions are: + + cairo_set_target_gl + cairo_gl_surface_create + +Automatic detection of available backends +----------------------------------------- +The configure script now automatically detect what backends are +available, (use ./configure --disable-`backend' to prevent +compilation of specific backends). + +Snapshot 0.1.20 (2004-04-06 Carl Worth <cworth@isi.edu>) +======================================================== +New pattern API +--------------- +David Reveman has contributed a new pattern API which enable linear +and radial gradient patterns in addition to the original surface-based +patterns. The significant new top-level functions are: + + cairo_pattern_create_linear + cairo_pattern_create_radial + cairo_pattern_create_for_surface + cairo_pattern_add_color_stop + cairo_set_pattern + +Any code using the old cairo_set_pattern, (which accepted a +cairo_surface_t rather than a cairo_pattern_t), will need to be +updated. + +Update to XCB backend +--------------------- +The XCB backend is now enabled by default, (use ./configure +--disable-xcb to turn it off). + +Faster clipping +--------------- +Graydon Hoare has added optimizations that make cairo_clip much faster +when the path is a pixel-aligned, rectangular region. + +Bug fixes. + +Snapshot 0.1.19 (2004-02-24 Carl Worth <cworth@isi.edu>) +======================================================== +New PNG backend +--------------- +Olivier Andrieu contributed a new PNG backend. It builds on the +existing image backend to make it easy to render "directly" to a +.png file. The user never needs to deal with the actual image +buffer. The significant new functions are: + + cairo_set_target_png + cairo_png_surface_create + +The PNG backend is not enabled by default so that by default there is +not a new dependency on libpng. Use ./configure --enable-png to enable +this backend. + +Snapshot 0.1.18 (2004-02-17 Carl Worth <cworth@isi.edu>) +======================================================== +Path query functionality +------------------------ +It's now possible to query the current path. The two new functions +are: + + cairo_current_path + cairo_current_path_flat + +Each function accepts a number of callback functions that will be +called for each element in the path (move_to, line_to, curve_to, +close_path). The cairo_current_path_flat function does not accept a +curve_to callback. Instead, all curved portions of the path will be +converted to line segments, (within the current tolerance value). This +can be handy for doing things like text-on-path without having to +manually interpolate Bézier splines. + +New XCB backend +--------------- +Jamey Sharp has contributed a second X backend that uses the new, lean +XCB library rather than Xlib. It cannot currently be compiled at the +same time as the Xlib backend. See ./configure --enable-xcb. + +Build fixes for cygwin. + +Bug fixes. + +Snapshot 0.1.17 (2003-12-16 Carl Worth <cworth@isi.edu>) +======================================================== + +Better text support +------------------- +This snapshot provides much better text support by implementing the +following four functions: + + cairo_text_extents + cairo_glyph_extents + cairo_text_path + cairo_glyph_path + +The text/glyph_extents functions can be used to determine the bounding +box (and advance) for text as if drawn by show_text/glyphs. + +The text/glyph_path objects functions place text shapes on the current +path, where they can be subsequently manipulated. For example, +following these functions with cairo_stroke allows outline text to be +drawn. Calling cairo_clip allows clipping to a text-shaped region. + +Combined dependencies +--------------------- +The cairo core now depends only on the libpixman library. This single +library replaces the three previous libraries libic, libpixregion, and +slim. Thanks to Dave Beckett <dave.beckett@bristol.ac.uk> for all of +the heavy lifting with this renaming effort. + +Conditional compilation of backends +----------------------------------- +Cairo now allows optional backends to be disabled at compile time. The +following options may now be passed to the configure script: + + --disable-xlib + --disable-ps + +Note that the first option is a change from the old --without-x option +which will no longer have any effect. + +OS X supported - several byte-order issues resolved +--------------------------------------------------- +Cairo has now been successfully compiled under OS X. Testing revealed +that there were some byte-order problems in the PostScript backend and +the PNG generation in the demos. These have now been resolved. + +2003-10 +======= +Graydon Hoare <graydon@redhat.com> implemented the first real text +support using Freetype/fontconfig, (previous versions of cairo used +Xft and could only draw text when using an X backend). + +2003-09 +======= +Graydon Hoare <graydon@redhat.com> added the first real support for +running cairo with a non-render-aware X server. + +Jamey Sharp <jamey@minilop.net> virtualized the backend font and +surface interfaces in September, 2003. + +2003-06 +======= +Xr is renamed cairo to avoid confusion since it no longer had a strict +dependence on X. + +2003-05 +======= +A new image surface backend is added to Xr. Keith Packard +<keithp@keithp.com> wrote the image compositing code in libic that is +used for the image_surface backend. This code was originally written +as the software fallback for the render extension within the X +server. + +2002-06 +======= +Carl Worth <cworth@isi.edu> wrote the first lines of Xr, after Keith +Packard <keithp@keithp.com> proposed the plan for a stateful drawing +library in C providing a PostScript-like rendering model. + + LocalWords: mutex BeOS extraordinaire distro's URL lcd bool tarball diff --git a/PORTING_GUIDE b/PORTING_GUIDE new file mode 100644 index 000000000..7488173c4 --- /dev/null +++ b/PORTING_GUIDE @@ -0,0 +1,265 @@ + ...-----=======-----... + Cairo 1.0 Porting Guide + ...-----=======-----... + +Here are some notes on more easily porting cairo_code from cairo 0.4 +to cairo 1.0. It is sorted roughly in order of importance, (the items +near the top are expected to affect the most people). + +Automated API renamings +======================= +There have been a lot of simple renamings where the functionality is +the same but the name of the symbol is different. We have provided a +script to automate the conversion of these symbols. It can be found +within the cairo distribution in: + + util/cairo-api-update + +This script is used by installing it somewhere on your PATH, and the +running it and providing the names of your source files on the command +line. For example: + + cairo-api-update *.[ch] + +The script will first save backup copies of each file (renamed with a +.bak extension) and then will perform all of the simple renamings. + +For your benefit, the script also produces messages giving filenames +and line numbers for several of the manual API updates that you will +need to perform as described below. + + +Manual API changes +================== +This section of the porting guide describes changes you will have to +manually make to your source code. In addition to the information in +this guide, the cairo-api-update script will notify you of some of +these issues as described above. + +Cairo's deprecation warnings +---------------------------- +Also, if your compiler provides warnings for implicit declarations of +functions, (eg. "gcc -Wall"), then simply attempting to compile your +program will cause cairo to generate messages intended to guide you +through the porting process. + +For example, if you neglect to update an old call to +cairo_set_target_drawable, you might see an error message as follows: + + foo.c:10: warning: implicit declaration of function + ‘cairo_set_target_drawable_DEPRECATED_BY_cairo_xlib_surface_create’ + +This message is indicating to you that the deprecatd function +cairo_set_target_drawable appears in your program foo.c on line 10, +and you should rewrite your program to call cairo_xlib_surface_create +instead. + +The remainder of this porting guide is arranged as a set of common +code patterns that appear in old (cairo-0.4) code and how it should be +transformed to new (cairo-0.5) code. + +cairo_create +------------ +Was: cr = cairo_create (); + cairo_set_target_foo (cr, args); + /* draw */ + cairo_destroy (cr); + +Now: cairo_surface_t *surface; + + surface = cairo_foo_surface_create (args); + cr = cairo_create (surface); + /* draw */ + cairo_destroy (cr); + cairo_surface_destroy (surface); + +Or: cairo_surface_t *surface; + + surface = cairo_foo_surface_create (args); + cr = cairo_create (surface); + cairo_surface_destroy (surface); + /* draw */ + cairo_destroy (cr); + +NOTE: Many of the cairo_foo_surface_create functions accept the + identical arguments as the the old cairo_set_target_foo + functions, (minus the cairo_t*), making this transformation + quite easy. One notable exception is cairo_set_target_drawable + which, when it becomes cairo_xlib_surface_create must pickup new + arguments for the Visual*, the width, and the height. + +cairo_set_alpha (1) +------------------- +Was: cairo_set_rgb_color (cr, red, green, blue); + cairo_set_alpha (cr, alpha); + +Now: cairo_set_source_rgba (cr, red, green, blue, alpha); + +cairo_show_surface +------------------ +Was: cairo_show_surface (cr, surface, width, height); + +Now: cairo_set_source_surface (cr, surface, x, y); + cairo_paint (cr); + +NOTE: The type signatures of cairo_show_surface and cairo_set_source + are the same, but pay attention that cairo_show_surface required + the width and height, while cairo_set_source_surface requires + the X,Y location to where the surface will be placed. + +cairo_set_alpha (2) +------------------- +Was: cairo_set_alpha (cr, alpha); + cairo_show_surface (cr, surface, width, height); + +Now: cairo_set_source_surface (cr, surface, x, y); + cairo_paint_with_alpha (cr, alpha); + +filling and stroking +-------------------- +Was: cairo_save (cr); + /* set fill color */ + cairo_fiill (cr); + cairo_restore (cr); + /* set stroke color */ + cairo_stroke (cr); + +Now: /* set fill color */ + cairo_fill_preserve (cr); + /* set stroke color */ + cairo_stroke (cr); + +NOTE: The current path is no longer saved/restored by + cairo_save/cairo_restore. This can lead to some subtle + surprises, so look out. + +cairo_matrix_t +-------------- +Was: cairo_matrix_t *matrix; + + matrix = cairo_matrix_create (); + /* Do stuff with matrix */ + cairo_matrix_destroy (matrix); + +Now: cairo_matrix_t matrix; + cairo_matrix_init_identity (&matrix); + /* Do stuff with &matrix */ + +NOTE: If you are really lazy, you can still use a cairo_matrix_t* and + avoid putting the &matrix all over by just replacing + cairo_matrix_create() with malloc() and cairo_matrix_destroy() + with free(). That's not as nice, and you still need to be + careful to see if you need to initialize it to an identity + matrix as cairo_matrix_create() did for you. + +Rendering to a temporary surface +-------------------------------- +Was: cairo_save (cr); + { + cairo_set_target_surface (cr, temporary); + /* draw through cr onto temporary */ + } + cairo_restore (cr); + /* use temporary as source on cr */ + +Now: { + cr2 = cairo_create (temporary); + /* draw through cr2 onto temporary */ + cairo_destory (cr2); + } + /* use temporary as source on cr */ + +NOTE: Having to create another cairo_t is a bit annoying, but having + to invent a new name for it is just awful, (imagine a deeply + nested version of this code). Fortunately, the style above is + just a stop-gap measure until the new group API comes along. + +Iterating over a path +--------------------- +Was: cairo_current_path (cr, + my_move_to, + my_line_to, + my_curve_to, + my_close_path, + closure); + +Now: int i; + cairo_path_t *path; + cairo_path_data_t *data; + + path = cairo_copy_path (cr); + + for (i=0; i < path->num_data; i += path->data[i].header.length) { + data = &path->data[i]; + switch (data->header.type) { + case CAIRO_PATH_MOVE_TO: + my_move_to (closure, data[1].point.x, data[1].point.y); + break; + case CAIRO_PATH_LINE_TO: + my_line_to (closure, data[1].point.x, data[1].point.y); + break; + case CAIRO_PATH_CURVE_TO: + my_curve_to (closure, data[1].point.x, data[1].point.y, + data[2].point.x, data[2].point.y, + data[3].point.x, data[3].point.y); + break; + case CAIRO_PATH_CLOSE_PATH: + my_close_path (closure); + break; + } + } + cairo_path_destroy (path); + +NOTE: This version makes it looks like the new form is a _lot_ more + verbose than the old version. But realize that the old version + required the support of 4 additional functions. The new approach + allows great flexibility including the ability to inline the + entire operation within the switch statement when appropriate. + +Erasing a surface to transparent +-------------------------------- +Was: cairo_set_rgb_color (cr, 0., 0., 0.); + cairo_set_alpha (cr, 0.) + cairo_set_operator (cr, CAIRO_OPERATOR_SRC); + cairo_rectangle (cr, 0., 0., surface_width, surface_height); + cairo_fill (cr); + + or: cairo_set_rgb_color (cr, 0., 0., 0.); + cairo_set_operator (cr, CAIRO_OPERATOR_CLEAR); + cairo_rectangle (cr, 0., 0., surface_width, surface_height); + cairo_fill (cr); + +Now: cairo_set_source_rgba (cr, 0., 0., 0., 0.); + cairo_set_operator (cr, CAIRO_OPERATOR_SOURCE); + cairo_paint (cr); + + or: cairo_set_operator (cr, CAIRO_OPERATOR_CLEAR); + cairo_paint (cr); + +NOTE: Using cairo_rectangle and fill would still work just fine. It's + just a lot more convenient to use cairo_paint now, (particularly + as it doesn't require you to even know what the bounds of the + target surface are). + +Drawing to a PNG file +--------------------- +Was: file = fopen (filename, "w"); + cr = cairo_create (); + cairo_set_target_png (cr, file, format, width, height); + /* draw image */ + cairo_destroy (cr); + fclose (file); + +Now: surface = cairo_image_surface_create (format, width, height); + cr = cairo_create (surface); + /* draw image */ + cairo_surface_write_to_png (surface, filename); + cairo_destroy (cr); + cairo_surface_destroy (surface); + +NOTE: The png backend is gone. So there is no cairo_png_surface_create + to take the place of cairo_set_target_png. And notice that we + used an image surface here, but it is just as easy to use + cairo_surface_write_to_png with an xlib or other surface, (but + not PDF at the moment). This is one of the big advantages of + this approach as opposed to a PNG surface. diff --git a/README b/README new file mode 100644 index 000000000..0be9947d5 --- /dev/null +++ b/README @@ -0,0 +1,204 @@ +Cairo - Multi-platform 2D graphics library +http://cairographics.org + +What is cairo +============= +Cairo is a 2D graphics library with support for multiple output +devices. Currently supported output targets include the X Window +System (via both Xlib and XCB), quartz, win32, and image buffers, +as well as PDF, PostScript, and SVG file output. Experimental backends +include OpenGL, BeOS, OS/2, and DirectFB. + +Cairo is designed to produce consistent output on all output media +while taking advantage of display hardware acceleration when available +(for example, through the X Render Extension). + +The cairo API provides operations similar to the drawing operators of +PostScript and PDF. Operations in cairo include stroking and filling +cubic Bézier splines, transforming and compositing translucent images, +and antialiased text rendering. All drawing operations can be +transformed by any affine transformation (scale, rotation, shear, +etc.). + +Cairo has been designed to let you draw anything you want in a modern +2D graphical user interface. At the same time, the cairo API has been +designed to be as fun and easy to learn as possible. If you're not +having fun while programming with cairo, then we have failed +somewhere---let us know and we'll try to fix it next time around. + +Cairo is free software and is available to be redistributed and/or +modified under the terms of either the GNU Lesser General Public +License (LGPL) version 2.1 or the Mozilla Public License (MPL) version +1.1. + +Where to get more information about cairo +========================================= +The primary source of information about cairo is: + + http://cairographics.org/ + +The latest versions of cairo can always be found at: + + http://cairographics.org/download + +Documentation on using cairo and frequently-asked questions: + + http://cairographics.org/documentation + http://cairographics.org/FAQ + +Mailing lists for contacting cairo users and developers: + + http://cairographics.org/lists + +Roadmap and unscheduled things to do, (please feel free to help out): + + http://cairographics.org/roadmap + http://cairographics.org/todo + +Dependencies +============ +The set of libraries needed to compile cairo depends on which backends +are enabled when cairo is configured. So look at the list below to +determine which dependencies are needed for the backends of interest. + +For the surface backends, we have both "supported" and "experimental" +backends. Further, the supported backends can be divided into the +"standard" backends which can be easily built on any platform, and the +"platform" backends which depend on some underlying platform-specific +system, (such as the X Window System or some other window system). + +As an example, for a standard Linux build similar to what's shipped by +your distro, (with image, png, pdf, PostScript, svg, and xlib surface +backends, and the freetype font backend), the following sample commands +will install necessary dependencies: + + Debian (and similar): + + apt-get build-dep cairo + + Fedora (and similar): + + yum install libpng-devel zlib-devel libXrender-devel fontconfig-devel + +Technically you probably don't need pixman from the distribution since +if you're manually compiling Cairo you probably want an updated pixman +as well. However, if you follow the default settings and install pixman +to /usr/local, your Cairo build should properly use it in preference to +the system pixman. + + +Supported, "standard" surface backends +------------------------------------ + image backend (required) + ------------------------ + pixman >= 0.30.0 http://cairographics.org/releases + + png support (can be left out if desired, but many + ----------- applications expect it to be present) + libpng http://www.libpng.org/pub/png/libpng.html + + pdf backend + ----------- + zlib http://www.gzip.org/zlib + + postscript backend + ------------------ + zlib http://www.gzip.org/zlib + + svg backend + ----------- + [none] + +Supported, "platform" surface backends +----------------------------------- + xlib backend + ------------ + X11 http://freedesktop.org/Software/xlibs + + xlib-xrender backend + -------------------- + Xrender >= 0.6 http://freedesktop.org/Software/xlibs + + quartz backend + -------------- + MacOS X >= 10.5 with Xcode >= 3.0 + + win32 backend + ------------- + Microsoft Windows 2000 or newer[*]. + + xcb backend + ----------- + XCB http://xcb.freedesktop.org + +Font backends (required to have at least one) +--------------------------------------------- + freetype font backend + --------------------- + freetype >= 2.1.9 http://freetype.org + fontconfig http://fontconfig.org + + quartz-font backend + ------------------- + MacOS X >= 10.4 with Xcode >= 2.4 + + win32 font backend + ------------------ + Microsoft Windows 2000 or newer[*]. + + [*] The Win32 backend should work on Windows 2000 and newer + (excluding Windows Me.) Most testing has been done on + Windows XP. While some portions of the code have been + adapted to work on older versions of Windows, considerable + work still needs to be done to get cairo running in those + environments. + + Cairo can be compiled on Windows with either the gcc + toolchain (see http://www.mingw.org) or with Microsoft + Visual C++. If the gcc toolchain is used, the standard + build instructions using configure apply, (see INSTALL). + If Visual C++ is desired, GNU make is required and + Makefile.win32 can be used via 'make -f Makefile.win32'. + The compiler, include paths, and library paths must be set + up correctly in the environment. + + MSVC versions earlier than 7.1 are known to miscompile + parts of cairo and pixman, and so should be avoided. MSVC + 7.1 or later, including the free Microsoft Visual Studio + Express editions, produce correct code. + +Experimental surface backends +----------------------------- + beos backend + ------------ + No dependencies in itself other than an installed BeOS system, but cairo + requires a font backend.

You can use a +UNIX emulation based setup, such as Cygwin or MSYS, with the +conventional configure script shipped with Cairo releases. In this +configuration, you will build with GCC and (implicitly) libtool. In +the Cygwin case you end up with a DLL that depends on Cygwin and +should be used only from Cygwin applications. In the MSYS case you end +up with a "normal" Win32 DLL that can be used either from GCC- or +Microsoft Visual C++-compiled code. In theory, this technique is no +different than the ordinary build process for the Cairo library. In +practise there are lots of small details that can go wrong. + +The second way is to use a GNU-compatible make, but build using +Microsoft's Visual C++ compiler to produce native libraries. This is +the setup this README.win32 is written for. Also the DLL produced this +way is usable either from GCC- or MSVC-compiled code. + +Tools required +============== +You will need GNU make, version 3.80 or later. Earlier versions or +other modern make implementations may work, but are not guaranteed to. + +You will also need Microsoft Visual C++. Version 7 has been most +heavily tested, but other versions are likely to work fine. + +Libraries required +================== +Cairo requires a compatible version of the pixman library. Full build +instructions are beyond the scope of this document; however, using the +same tools, it should be possible to build pixman simply by entering +the pixman/src directory and typing: + + make -f Makefile.win32 CFG=release + +Depending on your feature set, you may also need zlib and libpng. + +Building +======== +There are a few files that you will need to edit. First, you must +determine which features will be built. Edit +build/Makefile.win32.features and set the features as desired. Note +that most features have external dependencies; specifically, +CAIRO_HAS_PNG_FUNCTIONS requires libpng to be present, and +CAIRO_HAS_PS_SURFACE and CAIRO_HAS_PDF_SURFACE both require zlib. + +To ensure that the compiler can find all dependencies, you may need to +edit build/Makefile.win32.common. In particular, ensure that +PIXMAN_CFLAGS contains a -I parameter pointing to the location of +your pixman header files and that PIXMAN_LIBS points to the actual +location of your pixman-1.lib file. You may also need to edit the +various occurrences of CAIRO_LIBS to point to other libraries +correctly. Note also that if you wish to link statically with zlib, +you should replace zdll.lib with zlib.lib. + +Finally, from the top Cairo directory, type: + + make -f Makefile.win32 CFG=release + +If this command succeeds, you will end up with src/release/cairo.dll. +To successfully use Cairo from your own programs, you will probably +want to move this file to some central location. You will also +probably want to copy the Cairo header files. These should be placed +in a cairo subdirectory (for instance, c:/code/common/include/cairo). +The exact set to copy depends on your features and is reported to you +at the end of the build. diff --git a/RELEASING b/RELEASING new file mode 100644 index 000000000..f6f5eeb51 --- /dev/null +++ b/RELEASING @@ -0,0 +1,142 @@ +Here are the steps to follow to create a new cairo release: + +1) Ensure that there are no local, uncommitted/unpushed + modifications.

Also make + sure you have libglib2.0-doc installed (else you'll get excessive + gtk-doc cross reference warnings in the next step). + +2) Verify that the code passes "make distcheck" + + First, make sure you have 'nm' and 'readelf' commands in PATH. + this should be OK with any Linux distro. + + Running "make distcheck" should result in no warnings or + errors and end with a message of the form: + + ============================================= + cairo-X.Y.Z archives ready for distribution: + cairo-X.Y.Z.tar.gz + ============================================= + + (But the tar file isn't actually ready yet, as we still have + some more steps to follow). + + Note that it's allowed (and perhaps recommended) to run the + "make distcheck" step against an all-software X server such as + Xvfb to avoid getting tripped up by any X-server-driver-specific + bugs. See test/README for details + + If you get errors about local PLT entries, you get the list of + cairo entries with the error. For each of these, a call to + slim_hidden_def and slim_hidden_proto is needed in the cairo + implementation in the style of other similar calls. + + In the unfortunate case that you have to push a snapshot out + (note, I said snapshot, not release) without the entire test + suite passing, here's the magic env vars to set when doing + 'make distcheck' and 'make release-publish' that will let you + get away with it. At any cost, never ever release without + (implied) distchecking. Every time we got around it, it turned + out to be a disaster. Anyway, here's the pass code: + + DISPLAY= CAIRO_TEST_TARGET=" " + +3) Fill out an entry in the NEWS file + + Sift through the logs since the last release. This is most + easily done with a command such as: + + git log --stat X.Y.Z.. + + where X.Y.Z is the previous release version. + + Summarize major changes briefly in a style similar to other + entries in NEWS. Take special care to note any additions in + the API. These should be easy to find by noting modifications + to .h files in the log command above. And more specifically, + the following command will show each patch that has changed a + public header file since the given version: + + find src/ -name '*.h' ! -name '*-private.h' ! -name 'cairoint.h' ! -name 'cairo-*features*.h' | \ + xargs git diff X.Y.Z.. -- + +4) Increment cairo_version_{minor|micro} in cairo-version.h: + + If there are backward-incompatible changes in the API, stop + now and don't release. Go back and fix the API instead. Cairo + is intended to remain backwards-compatible as far as API. + + So cairo_version_major will not be incremented unless we come + up with a new versioning scheme to take advantage of it. + + If there are API additions, then increment cairo_version_minor + and reset cairo_version_micro to 0. NOTE: The minor version is + only incremented for releases, not for snapshots. + + Otherwise, (i.e. there are only bug fixes), increment + cairo_version_micro to the next larger (even) number. + +5) Commit the changes to NEWS and cairo-version.h + + It's especially important to mention the new version number in your + commit log. + +6) Run "make release-publish" which will perform the following steps + for you: + + * Generate ChangeLog files out of git repository + * Check that ChangeLog files were generated properly + * Check that the version number ends with an even micro component + * Check that no release exists with the current version + * Verify that make distcheck completes successfully + * Generate the final tar file + * Generate an sha1sum file + * Sign the sha1sum using your GPG setup (asks for your GPG password) + * scp the three files to appear on http://cairographics.org/releases + * Generate a versioned manual and upload it to appear as both: + http://cairographics.org/manual-X.Y.Z + http://cairographics.org/manual + * Place local copies of the three files in the releases directory + * Create a LATEST-package-version file (after deleting any old one) + * Tag the entire source tree with a tag of the form X.Y.Z, and sign + the tag with your GPG key (asks for your GPG password, and you + may need to set GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL to match + your public-key's setting or this fails.) + * Provide some text for the release announcement (see below). + If for some reason you lost this message, "make release-publish-message" + prints it for you. + +7) Increment cairo_version_micro to the next larger (odd) number in + cairo-version.h, commit, and push. + +8) Push the newly created tag out to the central tree with a command + something like: + + git push upstream master X.Y.Z + +9) Edit the cairo bugzilla product and add the new version numbers.

It is used heavily in the +dnl macro _AX_PATH_BDB for library checking. Due to the various number +dnl of minor-version numbers that can exist, and the fact that string +dnl comparisons are not compatible with numeric comparisons, this is +dnl not necessarily trivial to do in a autoconf script. This macro +dnl makes doing these comparisons easy. +dnl +dnl The six basic comparisons are available, as well as checking +dnl equality limited to a certain number of minor-version levels. +dnl +dnl The operator OP determines what type of comparison to do, and can +dnl be one of: +dnl +dnl eq - equal (test A == B) +dnl ne - not equal (test A != B) +dnl le - less than or equal (test A <= B) +dnl ge - greater than or equal (test A >= B) +dnl lt - less than (test A < B) +dnl gt - greater than (test A > B) +dnl +dnl Additionally, the eq and ne operator can have a number after it to +dnl limit the test to that number of minor versions. +dnl +dnl eq0 - equal up to the length of the shorter version +dnl ne0 - not equal up to the length of the shorter version +dnl eqN - equal up to N sub-version levels +dnl neN - not equal up to N sub-version levels +dnl +dnl When the condition is true, shell commands ACTION-IF-TRUE are run, +dnl otherwise shell commands ACTION-IF-FALSE are run.

+Error handling

+

+ The error handling approach in C for Cairo has multiple + elements: +

+
    +

  • + When a method on an object fails, the object is put into + an error state. Subsequent operations on the object do + nothing. The status of the object can be queried with + a function like status(). +

    • +
  • +

    + Constructors, rather than + returning NULL on out-of-memory failure, + return a special singleton object on which all + operations do nothing. Retrieving the status of the + singleton object returns CAIRO_STATUS_NO_MEMORY +

    +

    + Is this going to apply to + cairo_surface_t as well? +

    +

    + What about cairo_copy_path_data()? It's probably going to + have to return NULL. +

    +
    • +

  • + Errors propagate from object to object. Setting a pattern + in an out-of-memory state as the source of a + cairo_t puts the type into an error state. +

    • +
+

Much of the above is not yet implemented at the time of + this writing

+

+ A language binding could copy the C approach, and for a + language without exceptions, this is likely the right thing + to do. However, for a language with exceptions, exposing + a completely different style of error handling for cairo + would be strange. So, instead, status should be checked + after every call to cairo, and exceptions thrown as necessary. +

+

+ One problem that can arise with this, in languages + where handling exceptions is mandatory (like Java), is that almost + every cairo function can result in a status being set, + usually because of an out-of-memory condition. This could make + cairo hard to use. To resolve this problem, let's classify then + cairo status codes: +

+
+/* Memory */      
+CAIRO_STATUS_NO_MEMORY,
+
+/* Programmer error */      
+CAIRO_STATUS_INVALID_RESTORE
+CAIRO_STATUS_INVALID_POP_GROUP
+CAIRO_STATUS_NO_CURRENT_POINT
+CAIRO_STATUS_INVALID_MATRIX
+CAIRO_STATUS_NO_TARGET_SURFACE
+CAIRO_STATUS_INVALID_STRING
+CAIRO_STATUS_SURFACE_FINISHED
+CAIRO_STATUS_BAD_NESTING
+
+/* Language binding implementation */
+CAIRO_STATUS_NULL_POINTER
+CAIRO_STATUS_INVALID_PATH_DATA
+CAIRO_STATUS_SURFACE_TYPE_MISMATCH
+
+/* Other */      
+CAIRO_STATUS_READ_ERROR
+CAIRO_STATUS_WRITE_ERROR
+
+

+ If we look at these, the + CAIRO_STATUS_NO_MEMORY + should map to the native out-of-memory exception, which could + happen at any point in any case. Most of the others indicate + programmer error, and handling them in user code would be + silly. These should be mapped into whatever the language uses + for assertion failures, rather than errors that are normally + handled. (In Java, a subclass of Error rather than Exception, + perhaps.) And CAIRO_STATUS_READ_ERROR, + and CAIRO_STATUS_WRITE_ERROR can occur + only in very specific places. (In fact, as described + in the section called “Streams and File I/Oâ€, these errors may be + mapped into the language's native I/O error types.) + So, there really aren't exceptions that the programmer must + handle at most points in the Cairo API. +

+Memory management

+

+ The objects in cairo can roughly be divided into two types: + reference-counted, opaque types like + cairo_surface_t + and plain structures like + cairo_glyph_t. + cairo_path_t + and + cairo_path_data_t + are special cases and are treated separately in this appendix. +

+

+ Refcounted opaque types all have a + ..._reference() + function to increase the refcount by one and a + ..._destroy() to decrease the refcount + by one. These should not be exposed to the user of the language + binding, but rather used to implement memory management within + the language binding. The simplest way to do memory management + for a language binding is to treat the language binding object + as a simple handle to the cairo object. The language binding + object references the cairo object, and unreferences it when + finalized. This is the recommended method, though there are + a couple of caveats to be noted: +

+
    +

  • + Equality won't work as expected. You can have two language + objects for the same cairo and they won't necessarily + compare equal. If the language allows customizing the + equality operation, then this is fixable by comparing + the underlying pointers. It also can be fixed by creating + at most one language object per cairo object, and + uniquifying via a pin table (a hash + table that goes from cairo object to language object). + For cairo_surface_t you can use also + cairo_surface_set_user_data() + instead of a separate pin table. +

    • +
  • +

    + Derivation from the language object doesn't work because + you can lose the language object while keeping the Cairo + object. Code like: +

    +
    +public class MySurface (ImageSurface) {
+   public MySurface (width, height) {
+      super (Format.ARGB32, width, height);
+   }
+   public int get42 () {
+      return 42;	  
+   }
+}
+
+   cr = Cairo(MySurface(width, height));
+   surface = cr.getTarget();
+
    +

    + Can result in surface containing an + ImageSurface not a MySurface. + This is not easily fixable without creating memory leaks, + and it's probably best to simply forbid deriving from the + language objects. +

    +
    • +
+

+ When a plain structure is used as a return value from cairo, + this is done by passing it as a “out parameterâ€. +

+
+cairo_font_extents_t extents;      
+
+cairo_font_extents (cr, &extents);
+

+ In a language binding, this should typically be treated + as a return value: +

+
+FontExtents extents = cr.fontExtents ();
+

+ A language binding has a choice in how it implements the + language objects for plain structures. It can use a pure + language object with fields corresponding to those of the C + structure, and convert from and to the C structure when calling + cairo functions or converting cairo return values. Or it + can keep a pointer to the C structure internally and wrap + it inside a language object much like occurs for refcounted + objects. The choice should be invisible to the user: they should + be able to imagine that it is implemented as a pure language + object. +

+Overloading and optional arguments

+

+ Function overloading (having a several variants of a function + with the same name and different arguments) is a language + feature available in many languages but not in C. +

+

+ In general, language binding authors should use restraint in + combining functions in the cairo API via function + overloading. What may seem like an obvious overload now may + turn out to be strange with future additions to cairo. + It might seem logical to make + cairo_set_source_rgb() + an overload of cairo_set_source(), but future plans to add + cairo_set_source_rgb_premultiplied(), + which will also take three doubles make this a bad idea. For + this reason, only the following pairs of functions should + be combined via overloading +

+
+void
+cairo_set_source (cairo_t *cr, cairo_pattern_t *source);
+
+void
+cairo_set_source_surface (cairo_t          *cr,
+                          cairo_surface_t  *source,
+                          double            surface_x,
+                          double            surface_y);
+

+		    cairo_surface_t *surface,

+		    double           surface_y);
+

+			    int			width,
+			    int			height);
+cairo_surface_t *
+cairo_image_surface_create_for_data (unsigned char	       *data,
+				     cairo_format_t		format,
+				     int			width,
+				     int			height,
+				     int			stride);
+

+cairo_surface_write_to_png (cairo_surface_t	*surface,
+			    const char		*filename);
+
+cairo_status_t

+
+cairo_surface_t *
+cairo_image_surface_create_from_png_stream (cairo_read_func_t	read_func,
+					    void		*closure);
+
+

+ Note that there are cases where all constructors for a type + aren't overloaded together. For example + cairo_image_surface_create_from_png() + should not be overloaded together with + cairo_image_surface_create(). + In such cases, the remaining constructors will typically need to + be bound as static methods. In Java, for example, we might have: +

+
+Surface surface1 = ImageSurface(Format.RGB24, 100, 100);
+Surface surface2 = ImageSurface.createFromPNG("camera.png");
+

+ Some other overloads that add combinations not found in C may be + convenient for users for language bindings that provide + cairo_point_t and cairo_rectangle_t + types, for example: +

+
+void
+cairo_move_to (cairo_t       *cr,
+               cairo_point_t *point);
+void
+cairo_rectangle (cairo_t           *cr,

+cairo_path_t

+

+ The cairo_path_t type is one + area in which most language bindings will differ significantly + from the C API. The C API for cairo_path_t is + designed for efficiency and to avoid auxiliary objects that + would be have to be manually memory managed by the + application. However, + a language binding should not present cairo_path_t as an + array, but rather as an opaque that can be iterated + over. Different languages have quite different conventions for + how iterators work, so it is impossible to give an exact + specification for how this API should work, but the type names + and methods should be similar to the language's mapping of the following: +

+
+typedef struct cairo_path_iterator cairo_path_iterator_t;
+typedef struct cairo_path_element cairo_path_element_t;
+
+cairo_path_iterator_t *
+cairo_path_get_iterator (cairo_path_t *path);
+
+cairo_bool_t
+cairo_path_iterator_has_next (cairo_path_iterator_t *iterator);
+      
+cairo_path_element_t *
+cairo_path_iterator_next (cairo_path_iterator_t *iterator);
+
+cairo_path_element_type_t
+cairo_path_element_get_type (cairo_path_element_t *element);
+      
+void
+cairo_path_element_get_point (cairo_path_element_t *element,
+                              int                   index,
+                              double                *x,
+                              double                *y);
+
+

+ The above is written using the Java conventions for + iterators. To illustrate how the API for PathIterator might + depend on the native iteration conventions of the API, examine + three versions of the loop, first written in a hypothetical Java + binding: +

+
+PathIterator iter = cr.copyPath().iterator();
+while (cr.hasNext()) {
+    PathElement element = iter.next();
+    if (element.getType() == PathElementType.MOVE_TO) {
+        Point p = element.getPoint(0);
+        doMoveTo (p.x, p.y);
+    }
+}
+

+ And then in a hypothetical C++ binding: +

+
+Path path = cr.copyPath();
+for (PathIterator iter = path.begin(); iter != path.end(); iter++) {
+    PathElement element = *iter;
+    if (element.getType() == PathElementType.MOVE_TO) {
+        Point p = element.getPoint(0);
+        doMoveTo (p.x, p.y);
+    }
+}
+

+ And then finally in a Python binding: +

+
+for element in cr.copy_path():
+    if element.getType == cairo.PATH_ELEMENT_MOVE_TO:
+        (x, y) = element.getPoint(0)
+        doMoveTo (x, y);
+

+ While many of the API elements stay the same in the three + examples, the exact iteration mechanism is quite different, to + match how users of the language would expect to iterate over + a container. +

+

+ You should not present an API for mutating or for creating new + cairo_path_t objects. In the future, these + guidelines may be extended to present an API for creating a + cairo_path_t from scratch for use with + cairo_append_path() + but the current expectation is that cairo_append_path() will + mostly be used with paths from + cairo_copy_path(). +

+Multiple return values

+

+ There are a number of functions in the cairo API that have + multiple out parameters or + in-out parameters. In some languages + these can be translated into multiple return values. In Python, + what is: +

+
+cairo_user_to_device (cr, &x, &y);
+

+ can by mapped to: +

+
+(x, y) = cr.user_to_device (cr, x, y);
+

+ but many languages don't have provisions for multiple return + values, so it is necessary to introduce auxiliary types. + Most of the functions that require the auxiliary types + require a type that would, in C, look like +

+
+typedef struct _cairo_point cairo_point_t;
+struct _cairo_point {
+    double x;
+    double y;
+}
+

+ The same type should be used both for functions that use a pair + of coordinates as an absolute position, and functions that use + a pair of coordinates as a displacement. While an argument could + be made that having a separate “distance†type is more correct, + it is more likely just to confuse users. +

+
+void
+cairo_user_to_device (cairo_t *cr, double *x, double *y);
+
+void
+cairo_user_to_device_distance (cairo_t *cr, double *dx, double *dy);

+void
+cairo_device_to_user (cairo_t *cr, double *x, double *y);

+void
+cairo_matrix_transform_point (cairo_matrix_t *matrix, double *x, double *y);
+
+void
+cairo_get_current_point (cairo_t *cr, double *x, double *y);
+
+

+ There are also a couple of functions that return four values + representing a rectangle. These should be mapped to a + “rectangle†type that looks like: +

+
+typedef struct _cairo_rectangle cairo_rectangle_t;
+struct _cairo_rectangle {
+    double x;
+    double y;
+    double width;
+    double height;
+}
+

+ The C function returns the rectangle as a set of two points to + facilitate rounding to integral extents, but this isn't worth + adding a “box†type to go along with the more obvious + “rectangle†representation. +

+

+ Q: Would it make sense here to define a standard + cairo_rectangle_round() method + that language bindings should map? +

+Streams and File I/O

+

+ Various places in the cairo API deal with reading and writing + data, whether from and to files, or to other sources and + destinations. In these cases, what is typically provided in the + C API is a simple version that just takes a filename, and a + complex version that takes a callback function. + An example is the PNG handling functions: +

+
+cairo_surface_t *
+cairo_image_surface_create_from_png (const char	*filename);
+
+cairo_surface_t *
+cairo_image_surface_create_from_png_stream (cairo_read_func_t read_func,
+					    void             *closure);
+
+cairo_status_t
+cairo_surface_write_to_png (cairo_surface_t	*surface,
+			    const char		*filename);
+
+cairo_status_t
+cairo_surface_write_to_png_stream (cairo_surface_t	*surface,
+				   cairo_write_func_t	write_func,
+				   void			*closure);
+

+ The expectation is that the filename version will be mapped + literally in the language binding, but the callback version + will be mapped to a version that takes a language stream + object. For example, in Java, the four functions above + might be mapped to: +

+
+static public ImageSurface createFromPNG (String filename) throws IOException;
+static public ImageSurface createFromPNG (InputStream stream) throws IOException;
+public void writeToPNG (String filename) throws IOException;
+public void writeToPNG (OutputStream stream) throws IOException;
+
+

+ In many cases, it will be better to + implement the filename version internally + using the stream version, rather than building it on top of the + filename version in C. The reason for this is that will + naturally give a more standard handling of file errors for + the language, as seen in the above Java example, where + createFromPNG() is marked as raising + an exception. Propagating exceptions from inside the callback + function to the caller will pose a challenge to the language + binding implementor, since an exception must not propagate + through the Cairo code. A technique that will be useful in + some cases is to catch the exception in the callback, + store the exception object inside a structure pointed to by + closure, and then rethrow it once + the function returns. +

+

+ I'm not sure how to handle this for + cairo_pdf_surface_create_for_stream(). + Other than keep a “exception to rethrow†thread-specific + variable + that is checked after every call to a Cairo + function. +

+Surfaces

+ Like patterns, surfaces, which use only the + cairo_surface_t + type in the C API should be broken up into a hierarchy of types + in a language binding. +

+
+cairo_surface_t
+    cairo_image_surface_t
+    cairo_atsui_surface_t
+    cairo_win32_surface_t
+    cairo_xlib_surface_t
+    cairo_beos_surface_t
+
+

+ Unlike patterns, the constructors and methods on these types are + clearly named, and can be trivially associated with the + appropriate subtype. Many language bindings will want to avoid + binding the platform-specific subtypes at all, since the + methods on these types are not useful without passing in native + C types. Unless there is a language binding for Xlib available, + there is no way to represent a XLib Display * in + that language. +

+

+ This doesn't mean that platform-specific surface types can't + be used in a language binding that doesn't bind the constructor. + A very common situation is to use a cairo language binding in + combination with a binding for a higher level system like + the GTK+ widget + toolkit. In such a situation, the higher level toolkit provides + ways to get references to platform specific surfaces. +

+

+ The cairo_surface_set_user_data(), + and cairo_surface_get_user_data() + methods are provided for use in language bindings, and should + not be directly exposed to applications. One example of the use + of these functions in a language binding is creating a binding for: +

+
+cairo_surface_t *
+cairo_image_surface_create_for_data (unsigned char	       *data,
+				     cairo_format_t		format,
+				     int			width,
+				     int			height,
+				     int			stride);
+
+

+ The memory block passed in for data must be + kept around until the surface is destroyed, so the language + binding must have some way of determining when that happens. The + way to do this is to use the destroy + argument to cairo_surface_set_user_data(). +

+

+ Some languages may not have a suitable “pointer to a block of + data†type to pass in for data. And even + where a language does have such a type, the user will be + frequently able to cause the backing store to be reallocated + to a different location or truncated. Should we recommend a + standard type name and binding for a buffer object here? +

Description

+

Cairo uses a single status type to represent all kinds of errors. A status +value of CAIRO_STATUS_SUCCESS represents no error and has an integer value +of zero. All other status values represent an error.

+

Cairo's error handling is designed to be easy to use and safe. All major +cairo objects retain an error status internally which +can be queried anytime by the users using cairo*_status() calls. In +the mean time, it is safe to call all cairo functions normally even if the +underlying object is in an error status. This means that no error handling +code is required before or after each individual cairo function call.

+
+
+

Functions

+
+

cairo_status_to_string ()

+
const char *
+cairo_status_to_string (cairo_status_t status);
+

Provides a human-readable description of a cairo_status_t.

+
+

Parameters

+
+++++ + + + + + +

status

a cairo status

 
+
+
+

Returns

+

a string representation of the status

+

+
+

Since 1.0

+
+
+
+

cairo_debug_reset_static_data ()

+
void
+cairo_debug_reset_static_data (void);
+

Resets all static data within cairo to its original state, +(ie. identical to the state at the time of program invocation). For +example, all caches within cairo will be flushed empty.

+

This function is intended to be useful when using memory-checking +tools such as valgrind. When valgrind's memcheck analyzes a +cairo-using program without a call to cairo_debug_reset_static_data(), +it will report all data reachable via cairo's static objects as +"still reachable". Calling cairo_debug_reset_static_data() just prior +to program termination will make it easier to get squeaky clean +reports from valgrind.

+

WARNING: It is only safe to call this function when there are no +active cairo objects remaining, (ie. the appropriate destroy +functions have been called as necessary). If there are active cairo +objects, this call is likely to cause a crash, (eg. an assertion +failure due to a hash table being destroyed when non-empty).

+

Since 1.0

+
+
+
+

Types and Values

+
+

enum cairo_status_t

+

cairo_status_t is used to indicate errors that can occur when +using Cairo. In some cases it is returned directly by functions. +but when using cairo_t, the last error, if any, is stored in +the context and can be retrieved with cairo_status().

+

New entries may be added in future versions. Use cairo_status_to_string() +to get a human-readable representation of an error message.

Description

+

The FreeType font backend is primarily used to render text on GNU/Linux +systems, but can be used on other platforms too.

+
+
+

Functions

+
+

cairo_ft_font_face_create_for_ft_face ()

+
cairo_font_face_t *
+cairo_ft_font_face_create_for_ft_face (FT_Face face,
+                                       int load_flags);
+

Creates a new font face for the FreeType font backend from a +pre-opened FreeType face. This font can then be used with +cairo_set_font_face() or cairo_scaled_font_create(). The +cairo_scaled_font_t returned from cairo_scaled_font_create() is +also for the FreeType backend and can be used with functions such +as cairo_ft_scaled_font_lock_face(). Note that Cairo may keep a reference +to the FT_Face alive in a font-cache and the exact lifetime of the reference +depends highly upon the exact usage pattern and is subject to external +factors. You must not call FT_Done_Face() before the last reference to the +cairo_font_face_t has been dropped.

+

As an example, below is how one might correctly couple the lifetime of +the FreeType face object to the cairo_font_face_t.

+
+static const cairo_user_data_key_t key;
+
+font_face = cairo_ft_font_face_create_for_ft_face (ft_face, 0);
+status = cairo_font_face_set_user_data (font_face, &key,
+                               ft_face, (cairo_destroy_func_t) FT_Done_Face);
+if (status) {
+   cairo_font_face_destroy (font_face);
+   FT_Done_Face (ft_face);
+   return ERROR;
+}
+
+
+

Parameters

+
+++++ + + + + + + + + + + + + +

face

A FreeType face object, already opened. This must +be kept around until the face's ref_count drops to +zero and it is freed. Since the face may be referenced +internally to Cairo, the best way to determine when it +is safe to free the face is to pass a +cairo_destroy_func_t to cairo_font_face_set_user_data()

 

load_flags

flags to pass to FT_Load_Glyph when loading +glyphs from the font. These flags are OR'ed together with +the flags derived from the cairo_font_options_t passed +to cairo_scaled_font_create(), so only a few values such +as FT_LOAD_VERTICAL_LAYOUT, and FT_LOAD_FORCE_AUTOHINT +are useful. You should not pass any of the flags affecting +the load target, such as FT_LOAD_TARGET_LIGHT.

 
+
+
+

Returns

+

a newly created cairo_font_face_t. Free with +cairo_font_face_destroy() when you are done using it.

+

+
+

Since 1.0

+
+
+
+

cairo_ft_font_face_create_for_pattern ()

+
cairo_font_face_t *
+cairo_ft_font_face_create_for_pattern (FcPattern *pattern);
+

Creates a new font face for the FreeType font backend based on a +fontconfig pattern. This font can then be used with +cairo_set_font_face() or cairo_scaled_font_create(). The +cairo_scaled_font_t returned from cairo_scaled_font_create() is +also for the FreeType backend and can be used with functions such +as cairo_ft_scaled_font_lock_face().

+

Font rendering options are represented both here and when you +call cairo_scaled_font_create(). Font options that have a representation +in a FcPattern must be passed in here; to modify FcPattern +appropriately to reflect the options in a cairo_font_options_t, call +cairo_ft_font_options_substitute().

+

The pattern's FC_FT_FACE element is inspected first and if that is set, +that will be the FreeType font face associated with the returned cairo +font face. Otherwise the FC_FILE element is checked. If it's set, +that and the value of the FC_INDEX element (defaults to zero) of pattern + +are used to load a font face from file.

+

If both steps from the previous paragraph fails, pattern + will be passed +to FcConfigSubstitute, FcDefaultSubstitute, and finally FcFontMatch, +and the resulting font pattern is used.

+

If the FC_FT_FACE element of pattern + is set, the user is responsible +for making sure that the referenced FT_Face remains valid for the life +time of the returned cairo_font_face_t. See +cairo_ft_font_face_create_for_ft_face() for an example of how to couple +the life time of the FT_Face to that of the cairo font-face.

+
+

Parameters

+
+++++ + + + + + +

pattern

A fontconfig pattern. Cairo makes a copy of the pattern +if it needs to. You are free to modify or free pattern +after this call.

 
+
+
+

Returns

+

a newly created cairo_font_face_t. Free with +cairo_font_face_destroy() when you are done using it.

cairo_ft_font_options_substitute ()

+
void
+cairo_ft_font_options_substitute (const cairo_font_options_t *options,
+                                  FcPattern *pattern);
+

Add options to a FcPattern based on a cairo_font_options_t font +options object. Options that are already in the pattern, are not overridden, +so you should call this function after calling FcConfigSubstitute() (the +user's settings should override options based on the surface type), but +before calling FcDefaultSubstitute().

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

options

a cairo_font_options_t object

 

pattern

an existing FcPattern

+
+
+

cairo_ft_scaled_font_lock_face ()

+
FT_Face
+cairo_ft_scaled_font_lock_face (cairo_scaled_font_t *scaled_font);
+

cairo_ft_scaled_font_lock_face() gets the FT_Face object from a FreeType +backend font and scales it appropriately for the font. You must +release the face with cairo_ft_scaled_font_unlock_face() +when you are done using it. Since the FT_Face object can be +shared between multiple cairo_scaled_font_t objects, you must not +lock any other font objects until you unlock this one. A count is +kept of the number of times cairo_ft_scaled_font_lock_face() is +called. cairo_ft_scaled_font_unlock_face() must be called the same number +of times.

+

You must be careful when using this function in a library or in a +threaded application, because freetype's design makes it unsafe to +call freetype functions simultaneously from multiple threads, (even +if using distinct FT_Face objects). Because of this, application +code that acquires an FT_Face object with this call must add its +own locking to protect any use of that object, (and which also must +protect any other calls into cairo as almost any cairo function +might result in a call into the freetype library).

+
+

Parameters

+
+++++ + + + + + +

scaled_font

A cairo_scaled_font_t from the FreeType font backend. Such an +object can be created by calling cairo_scaled_font_create() on a +FreeType backend font face (see cairo_ft_font_face_create_for_pattern(), +cairo_ft_font_face_create_for_ft_face()).

 
+

Object Hierarchy

+
+
+

Description

+

Image surfaces provide the ability to render to memory buffers +either allocated by cairo or by the calling code. The supported +image formats are those defined in cairo_format_t.

+
+
+

Functions

+
+

cairo_format_stride_for_width ()

+
int
+cairo_format_stride_for_width (cairo_format_t format,
+                               int width);
+

This function provides a stride value that will respect all +alignment requirements of the accelerated image-rendering code +within cairo. Typical usage will be of the form:

+
+int stride;
+unsigned char *data;
+cairo_surface_t *surface;
+
+stride = cairo_format_stride_for_width (format, width);
+data = malloc (stride * height);
+surface = cairo_image_surface_create_for_data (data, format,
+					  width, height,
+					  stride);
+
+
+

Parameters

+
+++++ + + + + + + + + + + + + +

format

A cairo_format_t value

 

width

The desired width of an image surface to be created.

 
+
+
+

Returns

+

the appropriate stride to use given the desired +format and width, or -1 if either the format is invalid or the width +too large.

+

+
+

Since 1.6

+
+
+
+

cairo_image_surface_create ()

+
cairo_surface_t *
+cairo_image_surface_create (cairo_format_t format,
+                            int width,
+                            int height);
+

Creates an image surface of the specified format and +dimensions. Initially the surface contents are all

+

  1. (Specifically, within each pixel, each color or alpha channel +belonging to format will be 0. The contents of bits within a pixel, +but not belonging to the given format are undefined).

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

format

format of pixels in the surface to create

 

width

width of the surface, in pixels

 

height

height of the surface, in pixels

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if an error such as out of memory +occurs. You can use cairo_surface_status() to check for this.

+

+
+

Since 1.0

+
+
+
+

cairo_image_surface_create_for_data ()

+
cairo_surface_t *
+cairo_image_surface_create_for_data (unsigned char *data,
+                                     cairo_format_t format,
+                                     int width,
+                                     int height,
+                                     int stride);
+

Creates an image surface for the provided pixel data. The output +buffer must be kept around until the cairo_surface_t is destroyed +or cairo_surface_finish() is called on the surface. The initial +contents of data + will be used as the initial image contents; you +must explicitly clear the buffer, using, for example, +cairo_rectangle() and cairo_fill() if you want it cleared.

+

Note that the stride may be larger than +width*bytes_per_pixel to provide proper alignment for each pixel +and row. This alignment is required to allow high-performance rendering +within cairo. The correct way to obtain a legal stride value is to +call cairo_format_stride_for_width() with the desired format and +maximum image width value, and then use the resulting stride value +to allocate the data and to create the image surface. See +cairo_format_stride_for_width() for example code.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + +

data

a pointer to a buffer supplied by the application in which +to write contents. This pointer must be suitably aligned for any +kind of variable, (for example, a pointer returned by malloc).

 

format

the format of pixels in the buffer

 

width

the width of the image to be stored in the buffer

 

height

the height of the image to be stored in the buffer

 

stride

the number of bytes between the start of rows in the +buffer as allocated. This value should always be computed by +cairo_format_stride_for_width() before allocating the data +buffer.

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface in the case of an error such as out of +memory or an invalid stride value. In case of invalid stride value +the error status of the returned surface will be +CAIRO_STATUS_INVALID_STRIDE. You can use +cairo_surface_status() to check for this.

+

See cairo_surface_set_user_data() for a means of attaching a +destroy-notification fallback to the surface if necessary.

+

+
+

Since 1.0

+
+
+
+

cairo_image_surface_get_data ()

+
unsigned char *
+cairo_image_surface_get_data (cairo_surface_t *surface);
+

Get a pointer to the data of the image surface, for direct +inspection or modification.

+

A call to cairo_surface_flush() is required before accessing the +pixel data to ensure that all pending drawing operations are +finished. A call to cairo_surface_mark_dirty() is required after +the data is modified.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_image_surface_t

 
+
+
+

Returns

+

a pointer to the image data of this surface or NULL +if surface +is not an image surface, or if cairo_surface_finish() +has been called.

Description

+

The PDF surface is used to render cairo graphics to Adobe +PDF files and is a multi-page vector surface backend.

+

The following mime types are supported: CAIRO_MIME_TYPE_JPEG, +CAIRO_MIME_TYPE_JP2, CAIRO_MIME_TYPE_UNIQUE_ID, +CAIRO_MIME_TYPE_JBIG2, CAIRO_MIME_TYPE_JBIG2_GLOBAL, +CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID.

+

JBIG2 data in PDF must be in the embedded format as descibed in +ISO/IEC 11544. Image specific JBIG2 data must be in +CAIRO_MIME_TYPE_JBIG2. Any global segments in the JBIG2 data +(segments with page association field set to 0) must be in +CAIRO_MIME_TYPE_JBIG2_GLOBAL. The global data may be shared by +multiple images. All images sharing the same global data must set +CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID to a unique identifer. At least +one of the images must provide the global data using +CAIRO_MIME_TYPE_JBIG2_GLOBAL. The global data will only be +embedded once but shared by all JBIG2 images with the same +CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID.

Description

+

The PNG functions allow reading PNG images into image surfaces, and writing +any surface to a PNG file.

+

It is a toy API. It only offers very simple support for reading and +writing PNG files, which is sufficient for testing and +demonstration purposes. Applications which need more control over +the generated PNG file should access the pixel data directly, using +cairo_image_surface_get_data() or a backend-specific access +function, and process it with another library, e.g. gdk-pixbuf or +libpng.

+
+
+

Functions

+
+

cairo_image_surface_create_from_png ()

+
cairo_surface_t *
+cairo_image_surface_create_from_png (const char *filename);
+

Creates a new image surface and initializes the contents to the +given PNG file.

+
+

Parameters

+
+++++ + + + + + +

filename

name of PNG file to load

 
+
+
+

Returns

+

a new cairo_surface_t initialized with the contents +of the PNG file, or a "nil" surface if any error occurred. A nil +surface can be checked for with cairo_surface_status(surface) which +may return one of the following values:

+

CAIRO_STATUS_NO_MEMORY +CAIRO_STATUS_FILE_NOT_FOUND +CAIRO_STATUS_READ_ERROR

+

Alternatively, you can allow errors to propagate through the drawing +operations and check the status on the context upon completion +using cairo_status().

+

cairo_read_func_t is the type of function which is called when a +backend needs to read data from an input stream. It is passed the +closure which was specified by the user at the time the read +function was registered, the buffer to read the data into and the +length of the data in bytes. The read function should return +CAIRO_STATUS_SUCCESS if all the data was successfully read, +CAIRO_STATUS_READ_ERROR otherwise.

+
+

Parameters

closure

the input closure

 

data

the buffer into which to read the data

 

length

+
+
+

Returns

+

a new cairo_surface_t initialized with the contents +of the PNG file or a "nil" surface if the data read is not a valid PNG image +or memory could not be allocated for the operation. A nil +surface can be checked for with cairo_surface_status(surface) which +may return one of the following values:

+

CAIRO_STATUS_NO_MEMORY +CAIRO_STATUS_READ_ERROR

Description

+

Paths are the most basic drawing tools and are primarily used to implicitly +generate simple masks.

+
+
+

Functions

+
+

cairo_copy_path ()

+
cairo_path_t *
+cairo_copy_path (cairo_t *cr);
+

Creates a copy of the current path and returns it to the user as a +cairo_path_t. See cairo_path_data_t for hints on how to iterate +over the returned data structure.

+

This function will always return a valid pointer, but the result +will have no data (data==NULL and +num_data==0), if either of the following +conditions hold:

+
    +
  1. If there is insufficient memory to copy the path. In this + case path->status will be set to + CAIRO_STATUS_NO_MEMORY.
    2. +
  2. If cr is already in an error state. In this case + path->status will contain the same status that + would be returned by cairo_status().
    3. +
+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

the copy of the current path. The caller owns the +returned object and should call cairo_path_destroy() when finished +with it.

+

+
+

Since 1.0

+
+
+
+

cairo_copy_path_flat ()

+
cairo_path_t *
+cairo_copy_path_flat (cairo_t *cr);
+

Gets a flattened copy of the current path and returns it to the +user as a cairo_path_t. See cairo_path_data_t for hints on +how to iterate over the returned data structure.

+

This function is like cairo_copy_path() except that any curves +in the path will be approximated with piecewise-linear +approximations, (accurate to within the current tolerance +value). That is, the result is guaranteed to not have any elements +of type CAIRO_PATH_CURVE_TO which will instead be replaced by a +series of CAIRO_PATH_LINE_TO elements.

+

This function will always return a valid pointer, but the result +will have no data (data==NULL and +num_data==0), if either of the following +conditions hold:

+
    +
  1. If there is insufficient memory to copy the path. In this + case path->status will be set to + CAIRO_STATUS_NO_MEMORY.
    2. +
  2. If cr is already in an error state. In this case + path->status will contain the same status that + would be returned by cairo_status().
    3. +
+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

the copy of the current path. The caller owns the +returned object and should call cairo_path_destroy() when finished +with it.

+

+
+

Since 1.0

+
+
+
+

cairo_path_destroy ()

+
void
+cairo_path_destroy (cairo_path_t *path);
+

Immediately releases all memory associated with path +. After a call +to cairo_path_destroy() the path + pointer is no longer valid and +should not be used further.

+

Note: cairo_path_destroy() should only be called with a +pointer to a cairo_path_t returned by a cairo function. Any path +that is created manually (ie. outside of cairo) should be destroyed +manually as well.

+
+

Parameters

+
+++++ + + + + + +

path

a path previously returned by either cairo_copy_path() or +cairo_copy_path_flat().

 
+
+

Since 1.0

+
+
+
+

cairo_append_path ()

+
void
+cairo_append_path (cairo_t *cr,
+                   const cairo_path_t *path);
+

Append the path + onto the current path. The path + may be either the +return value from one of cairo_copy_path() or +cairo_copy_path_flat() or it may be constructed manually. See +cairo_path_t for details on how the path data structure should be +initialized, and note that path->status must be +initialized to CAIRO_STATUS_SUCCESS.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo context

 

path

path to be appended

 
+
+

Since 1.0

+
+
+
+

cairo_has_current_point ()

+
cairo_bool_t
+cairo_has_current_point (cairo_t *cr);
+

Returns whether a current point is defined on the current path. +See cairo_get_current_point() for details on the current point.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

whether a current point is defined.

+

+
+

Since 1.6

+
+
+
+

cairo_get_current_point ()

+
void
+cairo_get_current_point (cairo_t *cr,
+                         double *x,
+                         double *y);
+

Gets the current point of the current path, which is +conceptually the final point reached by the path so far.

+

The current point is returned in the user-space coordinate +system. If there is no defined current point or if cr + is in an +error status, x + and y + will both be set to 0.0. It is possible to +check this in advance with cairo_has_current_point().

+

Most path construction functions alter the current point. See the +following for details on how they affect the current point: +cairo_new_path(), cairo_new_sub_path(), +cairo_append_path(), cairo_close_path(), +cairo_move_to(), cairo_line_to(), cairo_curve_to(), +cairo_rel_move_to(), cairo_rel_line_to(), cairo_rel_curve_to(), +cairo_arc(), cairo_arc_negative(), cairo_rectangle(), +cairo_text_path(), cairo_glyph_path(), cairo_stroke_to_path().

+

Some functions use and alter the current point but do not +otherwise change current path: +cairo_show_text().

+

Some functions unset the current path and as a result, current point: +cairo_fill(), cairo_stroke().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

cr

a cairo context

 

x

return value for X coordinate of the current point

 

y

return value for Y coordinate of the current point

 
+
+

Since 1.0

+
+
+
+

cairo_new_path ()

+
void
+cairo_new_path (cairo_t *cr);
+

Clears the current path. After this call there will be no path and +no current point.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+

Since 1.0

+
+
+
+

cairo_new_sub_path ()

+
void
+cairo_new_sub_path (cairo_t *cr);
+

Begin a new sub-path. Note that the existing path is not +affected. After this call there will be no current point.

+

In many cases, this call is not needed since new sub-paths are +frequently started with cairo_move_to().

+

A call to cairo_new_sub_path() is particularly useful when +beginning a new sub-path with one of the cairo_arc() calls. This +makes things easier as it is no longer necessary to manually +compute the arc's initial coordinates for a call to +cairo_move_to().

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+

Since 1.2

+
+
+
+

cairo_close_path ()

+
void
+cairo_close_path (cairo_t *cr);
+

Adds a line segment to the path from the current point to the +beginning of the current sub-path, (the most recent point passed to +cairo_move_to()), and closes this sub-path. After this call the +current point will be at the joined endpoint of the sub-path.

+

The behavior of cairo_close_path() is distinct from simply calling +cairo_line_to() with the equivalent coordinate in the case of +stroking. When a closed sub-path is stroked, there are no caps on +the ends of the sub-path. Instead, there is a line join connecting +the final and initial segments of the sub-path.

+

If there is no current point before the call to cairo_close_path(), +this function will have no effect.

+

Note: As of cairo version 1.2.4 any call to cairo_close_path() will +place an explicit MOVE_TO element into the path immediately after +the CLOSE_PATH element, (which can be seen in cairo_copy_path() for +example). This can simplify path processing in some cases as it may +not be necessary to save the "last move_to point" during processing +as the MOVE_TO immediately after the CLOSE_PATH will provide that +point.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+

Since 1.0

+
+
+
+

cairo_arc ()

+
void
+cairo_arc (cairo_t *cr,
+           double xc,
+           double yc,
+           double radius,
+           double angle1,
+           double angle2);
+

Adds a circular arc of the given radius + to the current path. The +arc is centered at (xc +, yc +), begins at angle1 + and proceeds in +the direction of increasing angles to end at angle2 +. If angle2 + is +less than angle1 + it will be progressively increased by +2*M_PI until it is greater than angle1 +.

+

If there is a current point, an initial line segment will be added +to the path to connect the current point to the beginning of the +arc. If this initial line is undesired, it can be avoided by +calling cairo_new_sub_path() before calling cairo_arc().

+

Angles are measured in radians. An angle of 0.0 is in the direction +of the positive X axis (in user space). An angle of +M_PI/2.0 radians (90 degrees) is in the +direction of the positive Y axis (in user space). Angles increase +in the direction from the positive X axis toward the positive Y +axis. So with the default transformation matrix, angles increase in +a clockwise direction.

+

(To convert from degrees to radians, use degrees * (M_PI / +180.).)

+

This function gives the arc in the direction of increasing angles; +see cairo_arc_negative() to get the arc in the direction of +decreasing angles.

+

The arc is circular in user space. To achieve an elliptical arc, +you can scale the current transformation matrix by different +amounts in the X and Y directions. For example, to draw an ellipse +in the box given by x +, y +, width +, height +:

+
+cairo_save (cr);
+cairo_translate (cr, x + width / 2., y + height / 2.);
+cairo_scale (cr, width / 2., height / 2.);
+cairo_arc (cr, 0., 0., 1., 0., 2 * M_PI);
+cairo_restore (cr);
+
+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

cr

a cairo context

 

xc

X position of the center of the arc

+                    double radius,
+                    double angle1,
+                    double angle2);
+

Adds a circular arc of the given radius + to the current path. The +arc is centered at (xc +, yc +), begins at angle1 + and proceeds in +the direction of decreasing angles to end at angle2 +. If angle2 + is +greater than angle1 + it will be progressively decreased by +2*M_PI until it is less than angle1 +.

+

See cairo_arc() for more details. This function differs only in the +direction of the arc between the two angles.

+

Adds a cubic Bézier spline to the path from the current point to +position (x3 +, y3 +) in user-space coordinates, using (x1 +, y1 +) and +(x2 +, y2 +) as the control points. After this call the current point +will be (x3 +, y3 +).

+

If there is no current point before the call to cairo_curve_to() +this function will behave as if preceded by a call to +cairo_move_to(cr +, x1 +, y1 +).

cairo_rectangle ()

+
void
+cairo_rectangle (cairo_t *cr,
+                 double x,
+                 double y,
+                 double width,
+                 double height);
+

Adds a closed sub-path rectangle of the given size to the current +path at position (x +, y +) in user-space coordinates.

+

This function is logically equivalent to:

+
+cairo_move_to (cr, x, y);
+cairo_rel_line_to (cr, width, 0);
+cairo_rel_line_to (cr, 0, height);
+cairo_rel_line_to (cr, -width, 0);
+cairo_close_path (cr);
+
+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + +

cr

a cairo context

 

x

the X coordinate of the top left corner of the rectangle

 

y

the Y coordinate to the top left corner of the rectangle

 

width

the width of the rectangle

 

height

the height of the rectangle

+                  const cairo_glyph_t *glyphs,
+                  int num_glyphs);
+

Adds closed paths for the glyphs to the current path. The generated +path if filled, achieves an effect similar to that of +cairo_show_glyphs().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

cr

a cairo context

 

glyphs

array of glyphs to show

 

num_glyphs

number of glyphs to show

cairo_text_path ()

+
void
+cairo_text_path (cairo_t *cr,
+                 const char *utf8);
+

Adds closed paths for text to the current path. The generated +path if filled, achieves an effect similar to that of +cairo_show_text().

+

Text conversion and positioning is done similar to cairo_show_text().

+

Like cairo_show_text(), After this call the current point is +moved to the origin of where the next glyph would be placed in +this same progression. That is, the current point will be at +the origin of the final glyph offset by its advance values. +This allows for chaining multiple calls to to cairo_text_path() +without having to set current point in between.

+

Note: The cairo_text_path() function call is part of what the cairo +designers call the "toy" text API. It is convenient for short demos +and simple programs, but it is not expected to be adequate for +serious text-using applications. See cairo_glyph_path() for the +"real" text path API in cairo.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo context

 

utf8

a NUL-terminated string of text encoded in UTF-8, or NULL

+                    double dx3,
+                    double dy3);
+

Relative-coordinate version of cairo_curve_to(). All offsets are +relative to the current point. Adds a cubic Bézier spline to the +path from the current point to a point offset from the current +point by (dx3 +, dy3 +), using points offset by (dx1 +, dy1 +) and +(dx2 +, dy2 +) as the control points. After this call the current +point will be offset by (dx3 +, dy3 +).

+

Given a current point of (x, y), cairo_rel_curve_to(cr +, dx1 +, +dy1 +, dx2 +, dy2 +, dx3 +, dy3 +) is logically equivalent to +cairo_curve_to(cr +, x+dx1 +, y+dy1 +, x+dx2 +, y+dy2 +, x+dx3 +, y+dy3 +).

+

It is an error to call this function with no current point. Doing +so will cause cr + to shutdown with a status of +CAIRO_STATUS_NO_CURRENT_POINT.

+
+

Parameters

+cairo_rel_line_to (cairo_t *cr,
+                   double dx,

+

Relative-coordinate version of cairo_line_to(). Adds a line to the +path from the current point to a point that is offset from the +current point by (dx +, dy +) in user space. After this call the +current point will be offset by (dx +, dy +).

+

Given a current point of (x, y), cairo_rel_line_to(cr +, dx +, dy +) +is logically equivalent to cairo_line_to(cr +, x + dx +, y + dy +).

+

It is an error to call this function with no current point. Doing +so will cause cr + to shutdown with a status of +CAIRO_STATUS_NO_CURRENT_POINT.

+

Begin a new sub-path. After this call the current point will offset +by (x +, y +).

+

Given a current point of (x, y), cairo_rel_move_to(cr +, dx +, dy +) +is logically equivalent to cairo_move_to(cr +, x + dx +, y + dy +).

+                    double *x2,
+                    double *y2);
+

Computes a bounding box in user-space coordinates covering the +points on the current path. If the current path is empty, returns +an empty rectangle ((0,0), (0,0)). Stroke parameters, fill rule, +surface dimensions and clipping are not taken into account.

+

Contrast with cairo_fill_extents() and cairo_stroke_extents() which +return the extents of only the area that would be "inked" by +the corresponding drawing operations.

+

The result of cairo_path_extents() is defined as equivalent to the +limit of cairo_stroke_extents() with CAIRO_LINE_CAP_ROUND as the +line width approaches 0.0, (but never reaching the empty-rectangle +returned by cairo_stroke_extents() for a line width of 0.0).

+

Specifically, this means that zero-area sub-paths such as +cairo_move_to();cairo_line_to() segments, (even degenerate cases +where the coordinates to both calls are identical), will be +considered as contributing to the extents. However, a lone +cairo_move_to() will not contribute to the results of +cairo_path_extents().

+
+

Parameters

typedef struct {
+    cairo_status_t status;
+    cairo_path_data_t *data;
+    int num_data;
+} cairo_path_t;
+
+

A data structure for holding a path. This data structure serves as +the return value for cairo_copy_path() and +cairo_copy_path_flat() as well the input value for +cairo_append_path().

+

See cairo_path_data_t for hints on how to iterate over the +actual data within the path.

+

The num_data member gives the number of elements in the data +array. This number is larger than the number of independent path +portions (defined in cairo_path_data_type_t), since the data +includes both headers and coordinates for each portion.

+
+

Since 1.0

+
+
+
+

union cairo_path_data_t

+

cairo_path_data_t is used to represent the path data inside a +cairo_path_t.

+

The data structure is designed to try to balance the demands of +efficiency and ease-of-use. A path is represented as an array of +cairo_path_data_t, which is a union of headers and points.

+

Each portion of the path is represented by one or more elements in +the array, (one header followed by 0 or more points). The length +value of the header is the number of array elements for the current +portion including the header, (ie. length == 1 + # of points), and +where the number of points for each element type is as follows:

+
+    %CAIRO_PATH_MOVE_TO:     1 point
+    %CAIRO_PATH_LINE_TO:     1 point
+    %CAIRO_PATH_CURVE_TO:    3 points
+    %CAIRO_PATH_CLOSE_PATH:  0 points
+
+

The semantics and ordering of the coordinate values are consistent +with cairo_move_to(), cairo_line_to(), cairo_curve_to(), and +cairo_close_path().

+

Here is sample code for iterating through a cairo_path_t:

+
+     int i;
+     cairo_path_t *path;
+     cairo_path_data_t *data;
+ 
+     path = cairo_copy_path (cr);
+ 
+     for (i=0; i < path->num_data; i += path->data[i].header.length) {
+         data = &path->data[i];
+         switch (data->header.type) {
+         case CAIRO_PATH_MOVE_TO:
+             do_move_to_things (data[1].point.x, data[1].point.y);
+             break;
+         case CAIRO_PATH_LINE_TO:
+             do_line_to_things (data[1].point.x, data[1].point.y);
+             break;
+         case CAIRO_PATH_CURVE_TO:
+             do_curve_to_things (data[1].point.x, data[1].point.y,
+                                 data[2].point.x, data[2].point.y,
+                                 data[3].point.x, data[3].point.y);
+             break;
+         case CAIRO_PATH_CLOSE_PATH:
+             do_close_path_things ();
+             break;
+         }
+     }
+     cairo_path_destroy (path);
+
+

As of cairo 1.4, cairo does not mind if there are more elements in +a portion of the path than needed. Such elements can be used by +users of the cairo API to hold extra values in the path data +structure. For this reason, it is recommended that applications +always use data->header.length to +iterate over the path data, instead of hardcoding the number of +elements for each element type.

Description

+

The PostScript surface is used to render cairo graphics to Adobe +PostScript files and is a multi-page vector surface backend.

+
+
+

Functions

+
+

cairo_ps_surface_create ()

+
cairo_surface_t *
+cairo_ps_surface_create (const char *filename,
+                         double width_in_points,
+                         double height_in_points);
+

Creates a PostScript surface of the specified size in points to be +written to filename +. See cairo_ps_surface_create_for_stream() for +a more flexible mechanism for handling the PostScript output than +simply writing it to a named file.

+

Note that the size of individual pages of the PostScript output can +vary. See cairo_ps_surface_set_size().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

filename

a filename for the PS output (must be writable), NULL may be +used to specify no output. This will generate a PS surface that +may be queried and used as a source, without generating a +temporary file.

 

width_in_points

width of the surface, in points (1 point == 1/72.0 inch)

 

height_in_points

height of the surface, in points (1 point == 1/72.0 inch)

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if an error such as out of memory +occurs. You can use cairo_surface_status() to check for this.

+

+
+

+                                    double height_in_points);
+

Creates a PostScript surface of the specified size in points to be +written incrementally to the stream represented by write_func + and +closure +. See cairo_ps_surface_create() for a more convenient way +to simply direct the PostScript output to a named file.

+

Note that the size of individual pages of the PostScript +output can vary. See cairo_ps_surface_set_size().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

write_func

a cairo_write_func_t to accept the output data, may be NULL +to indicate a no-op write_func +. With a no-op write_func +, +the surface may be queried or used as a source without +generating any temporary files.

 

closure

the closure argument for write_func +

 

width_in_points

width of the surface, in points (1 point == 1/72.0 inch)

 

height_in_points

height of the surface, in points (1 point == 1/72.0 inch)

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if an error such as out of memory +occurs. You can use cairo_surface_status() to check for this.

+
+
+

cairo_ps_surface_dsc_begin_page_setup ()

+
void
+cairo_ps_surface_dsc_begin_page_setup (cairo_surface_t *surface);
+

This function indicates that subsequent calls to +cairo_ps_surface_dsc_comment() should direct comments to the +PageSetup section of the PostScript output.

+

This function call is only needed for the first page of a +surface. It should be called after any call to +cairo_ps_surface_dsc_begin_setup() and before any drawing is +performed to the surface.

+

See cairo_ps_surface_dsc_comment() for more details.

+
+

Parameters

+
+++++ + + + + + +

surface

a PostScript cairo_surface_t

cairo_ps_surface_dsc_comment ()

+
void
+cairo_ps_surface_dsc_comment (cairo_surface_t *surface,
+                              const char *comment);
+

Emit a comment into the PostScript output for the given surface.

+

The comment is expected to conform to the PostScript Language +Document Structuring Conventions (DSC). Please see that manual for +details on the available comments and their meanings. In +particular, the %%IncludeFeature comment allows a +device-independent means of controlling printer device features. So +the PostScript Printer Description Files Specification will also be +a useful reference.

+

The comment string must begin with a percent character (%) and the +total length of the string (including any initial percent +characters) must not exceed 255 characters. Violating either of +these conditions will place surface + into an error state. But +beyond these two conditions, this function will not enforce +conformance of the comment with any particular specification.

+

The comment string should not have a trailing newline.

+

The DSC specifies different sections in which particular comments +can appear. This function provides for comments to be emitted +within three sections: the header, the Setup section, and the +PageSetup section. Comments appearing in the first two sections +apply to the entire document while comments in the BeginPageSetup +section apply only to a single page.

+

For comments to appear in the header section, this function should +be called after the surface is created, but before a call to +cairo_ps_surface_dsc_begin_setup().

+

For comments to appear in the Setup section, this function should +be called after a call to cairo_ps_surface_dsc_begin_setup() but +before a call to cairo_ps_surface_dsc_begin_page_setup().

+

For comments to appear in the PageSetup section, this function +should be called after a call to +cairo_ps_surface_dsc_begin_page_setup().

+

Note that it is only necessary to call +cairo_ps_surface_dsc_begin_page_setup() for the first page of any +surface. After a call to cairo_show_page() or cairo_copy_page() +comments are unambiguously directed to the PageSetup section of the +current page. But it doesn't hurt to call this function at the +beginning of every page as that consistency may make the calling +code simpler.

+

As a final note, cairo automatically generates several comments on +its own. As such, applications must not manually generate any of +the following comments:

+

Header section: %!PS-Adobe-3.0, %%Creator, %%CreationDate, %%Pages, +%%BoundingBox, %%DocumentData, %%LanguageLevel, %%EndComments.

+

Setup section: %%BeginSetup, %%EndSetup

+

PageSetup section: %%BeginPageSetup, %%PageBoundingBox, %%EndPageSetup.

+

Other sections: %%BeginProlog, %%EndProlog, %%Page, %%Trailer, %%EOF

+

Here is an example sequence showing how this function might be used:

+
+cairo_surface_t *surface = cairo_ps_surface_create (filename, width, height);
+...
+cairo_ps_surface_dsc_comment (surface, "%%Title: My excellent document");
+cairo_ps_surface_dsc_comment (surface, "%%Copyright: Copyright (C) 2006 Cairo Lover")
+...
+cairo_ps_surface_dsc_begin_setup (surface);
+cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor White");
+...
+cairo_ps_surface_dsc_begin_page_setup (surface);
+cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *PageSize A3");
+cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *InputSlot LargeCapacity");
+cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaType Glossy");
+cairo_ps_surface_dsc_comment (surface, "%%IncludeFeature: *MediaColor Blue");
+... draw to first page here ..
+cairo_show_page (cr);

Description

+

The Quartz surface is used to render cairo graphics targeting the +Apple OS X Quartz rendering system.

+
+
+

Functions

+
+

cairo_quartz_surface_create ()

+
cairo_surface_t *
+cairo_quartz_surface_create (cairo_format_t format,
+                             unsigned int width,
+                             unsigned int height);
+

Creates a Quartz surface backed by a CGBitmap. The surface is +created using the Device RGB (or Device Gray, for A8) color space. +All Cairo operations, including those that require software +rendering, will succeed on this surface.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

format

format of pixels in the surface to create

 

width

width of the surface, in pixels

 

height

height of the surface, in pixels

 
+
+
+

Returns

+

the newly created surface.

+

+
+

cairo_surface_t *
+cairo_quartz_surface_create_for_cg_context
+                               (CGContextRef cgContext,
+                                unsigned int width,
+                                unsigned int height);
+

Creates a Quartz surface that wraps the given CGContext. The +CGContext is assumed to be in the standard Cairo coordinate space +(that is, with the origin at the upper left and the Y axis +increasing downward). If the CGContext is in the Quartz coordinate +space (with the origin at the bottom left), then it should be +flipped before this function is called. The flip can be accomplished +using a translate and a scale; for example:

+
+CGContextTranslateCTM (cgContext, 0.0, height);
+CGContextScaleCTM (cgContext, 1.0, -1.0);
+
+

All Cairo operations are implemented in terms of Quartz operations, +as long as Quartz-compatible elements are used (such as Quartz fonts).

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

cgContext

the existing CGContext for which to create the surface

 

width

width of the surface, in pixels

 

height

height of the surface, in pixels

 
+
+
+

Returns

+

the newly created Cairo surface.

+

+
+

Since 1.6

+
+
+
+

cairo_quartz_surface_get_cg_context ()

+
CGContextRef
+cairo_quartz_surface_get_cg_context (cairo_surface_t *surface);
+

Returns the CGContextRef that the given Quartz surface is backed +by.

+

A call to cairo_surface_flush() is required before using the +CGContextRef to ensure that all pending drawing operations are +finished and to restore any temporary modification cairo has made +to its state. A call to cairo_surface_mark_dirty() is required +after the state or the content of the CGContextRef has been +modified.

+
+

Parameters

+
+++++ + + + + + +

surface

the Cairo Quartz surface

 
+

Description

+

The raster source provides the ability to supply arbitrary pixel data +whilst rendering. The pixels are queried at the time of rasterisation +by means of user callback functions, allowing for the ultimate +flexibility. For example, in handling compressed image sources, you +may keep a MRU cache of decompressed images and decompress sources on the +fly and discard old ones to conserve memory.

+

For the raster source to be effective, you must at least specify +the acquire and release callbacks which are used to retrieve the pixel +data for the region of interest and demark when it can be freed afterwards. +Other callbacks are provided for when the pattern is copied temporarily +during rasterisation, or more permanently as a snapshot in order to keep +the pixel data available for printing.

+
+
+

Functions

+
+

cairo_pattern_create_raster_source ()

+
cairo_pattern_t *
+cairo_pattern_create_raster_source (void *user_data,

+                                    int height);
+

Creates a new user pattern for providing pixel data.

+

Use the setter functions to associate callbacks with the returned +pattern. The only mandatory callback is acquire.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

user_data

the user data to be passed to all callbacks

 

content

content type for the pixel data that will be returned. Knowing +the content type ahead of time is used for analysing the operation and +picking the appropriate rendering path.

 

width

maximum size of the sample area

 

height

maximum size of the sample area

+                                cairo_raster_source_release_func_t release);
+

Specifies the callbacks used to generate the image surface for a rendering +operation (acquire) and the function used to cleanup that surface afterwards.

+

+

cairo_raster_source_acquire_func_t is the type of function which is +called when a pattern is being rendered from. It should create a surface +that provides the pixel data for the region of interest as defined by +extents, though the surface itself does not have to be limited to that +area. For convenience the surface should probably be of image type, +created with cairo_surface_create_similar_image() for the target (which +enables the number of copies to be reduced during transfer to the +device). Another option, might be to return a similar surface to the +target for explicit handling by the application of a set of cached sources +on the device. The region of sample data provided should be defined using +cairo_surface_set_device_offset() to specify the top-left corner of the +sample data (along with width and height of the surface).

+
+

Parameters

+++++ + + + + + + + + + + + + + + + + + + + + + + +

pattern

the pattern being rendered from

 

callback_data

the user data supplied during creation

 

target

the rendering target surface

Object Hierarchy

+

Description

+

A recording surface is a surface that records all drawing operations at +the highest level of the surface backend interface, (that is, the +level of paint, mask, stroke, fill, and show_text_glyphs). The recording +surface can then be "replayed" against any target surface by using it +as a source surface.

+

If you want to replay a surface so that the results in target will be +identical to the results that would have been obtained if the original +operations applied to the recording surface had instead been applied to the +target surface, you can use code like this:

+
+cairo_t *cr;
+
+cr = cairo_create (target);
+cairo_set_source_surface (cr, recording_surface, 0.0, 0.0);
+cairo_paint (cr);
+cairo_destroy (cr);
+
+

A recording surface is logically unbounded, i.e. it has no implicit constraint +on the size of the drawing surface. However, in practice this is rarely +useful as you wish to replay against a particular target surface with +known bounds. For this case, it is more efficient to specify the target +extents to the recording surface upon creation.

+

The recording phase of the recording surface is careful to snapshot all +necessary objects (paths, patterns, etc.), in order to achieve +accurate replay. The efficiency of the recording surface could be +improved by improving the implementation of snapshot for the +various objects. For example, it would be nice to have a +copy-on-write implementation for _cairo_surface_snapshot.

+
+
+

Functions

+
+

cairo_recording_surface_create ()

+
cairo_surface_t *
+cairo_recording_surface_create (cairo_content_t content,
+                                const cairo_rectangle_t *extents);
+

Creates a recording-surface which can be used to record all drawing operations +at the highest level (that is, the level of paint, mask, stroke, fill +and show_text_glyphs). The recording surface can then be "replayed" against +any target surface by using it as a source to drawing operations.

+

The recording phase of the recording surface is careful to snapshot all +necessary objects (paths, patterns, etc.), in order to achieve +accurate replay.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

content

the content of the recording surface

 

extents

the extents to record in pixels, can be NULL to record +unbounded operations.

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

Object Hierarchy

+
+
+
+

Description

+

The SVG surface is used to render cairo graphics to +SVG files and is a multi-page vector surface backend.

+
+
+

Functions

+
+

cairo_svg_surface_create ()

+
cairo_surface_t *
+cairo_svg_surface_create (const char *filename,
+                          double width_in_points,
+                          double height_in_points);
+

Creates a SVG surface of the specified size in points to be written +to filename +.

+

The SVG surface backend recognizes the following MIME types for the +data attached to a surface (see cairo_surface_set_mime_data()) when +it is used as a source pattern for drawing on this surface: +CAIRO_MIME_TYPE_JPEG, CAIRO_MIME_TYPE_PNG, +CAIRO_MIME_TYPE_URI. If any of them is specified, the SVG backend +emits a href with the content of MIME data instead of a surface +snapshot (PNG, Base64-encoded) in the corresponding image tag.

+

The unofficial MIME type CAIRO_MIME_TYPE_URI is examined +first. If present, the URI is emitted as is: assuring the +correctness of URI is left to the client code.

+

If CAIRO_MIME_TYPE_URI is not present, but CAIRO_MIME_TYPE_JPEG +or CAIRO_MIME_TYPE_PNG is specified, the corresponding data is +Base64-encoded and emitted.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

filename

a filename for the SVG output (must be writable), NULL may be +used to specify no output. This will generate a SVG surface that +may be queried and used as a source, without generating a +temporary file.

 

width_in_points

width of the surface, in points (1 point == 1/72.0 inch)

 

height_in_points

height of the surface, in points (1 point == 1/72.0 inch)

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if an error such as out of memory +occurs. You can use cairo_surface_status() to check for this.

+

+
+

Since 1.2

+
+
+
+

cairo_svg_surface_create_for_stream ()

+
cairo_surface_t *
+cairo_svg_surface_create_for_stream (cairo_write_func_t write_func,

+                                     double width_in_points,
+                                     double height_in_points);
+

Creates a SVG surface of the specified size in points to be written +incrementally to the stream represented by write_func + and closure +.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

write_func

a cairo_write_func_t to accept the output data, may be NULL +to indicate a no-op write_func +. With a no-op write_func +, +the surface may be queried or used as a source without +generating any temporary files.

 

closure

width_in_points

width of the surface, in points (1 point == 1/72.0 inch)

 

height_in_points

height of the surface, in points (1 point == 1/72.0 inch)

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if an error such as out of memory +occurs. You can use cairo_surface_status() to check for this.

+

+
+

Since 1.2

Object Hierarchy

+
+
+
+
+

Description

+

The current transformation matrix, ctm, is a +two-dimensional affine transformation that maps all coordinates and other +drawing instruments from the user space into the +surface's canonical coordinate system, also known as the device +space.

+
+
+

Functions

+

+

Modifies the current transformation matrix (CTM) by translating the +user-space origin by (tx +, ty +). This offset is interpreted as a +user-space coordinate according to the CTM in place before the new +call to cairo_translate(). In other words, the translation of the +user-space origin takes place after any existing transformation.

+
+

Parameters

Description

+

The user-font feature allows the cairo user to provide drawings for glyphs +in a font. This is most useful in implementing fonts in non-standard +formats, like SVG fonts and Flash fonts, but can also be used by games and +other application to draw "funky" fonts.

+
+
+

Functions

+
+

cairo_user_scaled_font_init_func_t ()

+
cairo_status_t
+(*cairo_user_scaled_font_init_func_t) (cairo_scaled_font_t *scaled_font,
+                                       cairo_t *cr,
+                                       cairo_font_extents_t *extents);
+

cairo_user_scaled_font_init_func_t is the type of function which is +called when a scaled-font needs to be created for a user font-face.

+

The cairo context cr + is not used by the caller, but is prepared in font +space, similar to what the cairo contexts passed to the render_glyph +method will look like. The callback can use this context for extents +computation for example. After the callback is called, cr + is checked +for any error status.

+

The extents + argument is where the user font sets the font extents for +scaled_font +. It is in font space, which means that for most cases its +ascent and descent members should add to 1.0. extents + is preset to +hold a value of 1.0 for ascent, height, and max_x_advance, and 0.0 for +descent and max_y_advance members.

+

The callback is optional. If not set, default font extents as described +in the previous paragraph will be used.

+

Note that scaled_font + is not fully initialized at this +point and trying to use it for text operations in the callback will result +in deadlock.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

scaled_font

the scaled-font being created

 

cr

a cairo context, in font space

 

extents

font extents to fill in, in font space

 
+
+
+

Returns

+

CAIRO_STATUS_SUCCESS upon success, or an error status on error.

+                                cairo_text_extents_t *extents);
+

cairo_user_scaled_font_render_glyph_func_t is the type of function which +is called when a user scaled-font needs to render a glyph.

+

The callback is mandatory, and expected to draw the glyph with code glyph + to +the cairo context cr +. cr + is prepared such that the glyph drawing is done in +font space. That is, the matrix set on cr + is the scale matrix of scaled_font +, +The extents + argument is where the user font sets the font extents for +scaled_font +. However, if user prefers to draw in user space, they can +achieve that by changing the matrix on cr +. All cairo rendering operations +to cr + are permitted, however, the result is undefined if any source other +than the default source on cr + is used. That means, glyph bitmaps should +be rendered using cairo_mask() instead of cairo_paint().

+

Other non-default settings on cr + include a font size of 1.0 (given that +it is set up to be in font space), and font options corresponding to +scaled_font +.

+

The extents + argument is preset to have x_bearing, +width, and y_advance of zero, +y_bearing set to -font_extents.ascent, +height to font_extents.ascent+font_extents.descent, +and x_advance to font_extents.max_x_advance. +The only field user needs to set in majority of cases is +x_advance. +If the width field is zero upon the callback returning +(which is its preset value), the glyph extents are automatically computed +based on the drawings done to cr +. This is in most cases exactly what the +desired behavior is. However, if for any reason the callback sets the +extents, it must be ink extents, and include the extents of all drawing +done to cr + in the callback.

+
+

Parameters

cairo_user_scaled_font_text_to_glyphs_func_t ()

+
cairo_status_t
+(*cairo_user_scaled_font_text_to_glyphs_func_t)
+                               (cairo_scaled_font_t *scaled_font,
+                                const char *utf8,
+                                int utf8_len,
+                                cairo_glyph_t **glyphs,
+                                int *num_glyphs,
+                                cairo_text_cluster_t **clusters,
+                                int *num_clusters,
+                                cairo_text_cluster_flags_t *cluster_flags);
+

cairo_user_scaled_font_text_to_glyphs_func_t is the type of function which +is called to convert input text to an array of glyphs. This is used by the +cairo_show_text() operation.

+

Using this callback the user-font has full control on glyphs and their +positions. That means, it allows for features like ligatures and kerning, +as well as complex shaping required for scripts like +Arabic and Indic.

+

The num_glyphs + argument is preset to the number of glyph entries available +in the glyphs + buffer. If the glyphs + buffer is NULL, the value of +num_glyphs + will be zero. If the provided glyph array is too short for +the conversion (or for convenience), a new glyph array may be allocated +using cairo_glyph_allocate() and placed in glyphs +. Upon return, +num_glyphs + should contain the number of generated glyphs. If the value +glyphs + points at has changed after the call, the caller will free the +allocated glyph array using cairo_glyph_free(). The caller will also free +the original value of glyphs +, so the callback shouldn't do so. +The callback should populate the glyph indices and positions (in font space) +assuming that the text is to be shown at the origin.

+

If clusters + is not NULL, num_clusters + and cluster_flags + are also +non-NULL, and cluster mapping should be computed. The semantics of how +cluster array allocation works is similar to the glyph array. That is, +if clusters + initially points to a non-NULL value, that array may be used +as a cluster buffer, and num_clusters + points to the number of cluster +entries available there. If the provided cluster array is too short for +the conversion (or for convenience), a new cluster array may be allocated +using cairo_text_cluster_allocate() and placed in clusters +. In this case, +the original value of clusters + will still be freed by the caller. Upon +return, num_clusters + should contain the number of generated clusters. +If the value clusters + points at has changed after the call, the caller +will free the allocated cluster array using cairo_text_cluster_free().

+

The callback is optional. If num_glyphs + is negative upon +the callback returning or if the return value +is CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTED, the unicode_to_glyph callback +is tried. See cairo_user_scaled_font_unicode_to_glyph_func_t.

+

Note: While cairo does not impose any limitation on glyph indices, +some applications may assume that a glyph index fits in a 16-bit +unsigned integer. As such, it is advised that user-fonts keep their +glyphs in the 0 to 65535 range. Furthermore, some applications may +assume that glyph 0 is a special glyph-not-found glyph. User-fonts +are advised to use glyph 0 for such purposes and do not use that +glyph value for other purposes.

+                                unsigned long  unicode,
+                                unsigned long *glyph_index);
+

cairo_user_scaled_font_unicode_to_glyph_func_t is the type of function which +is called to convert an input Unicode character to a single glyph. +This is used by the cairo_show_text() operation.

+

This callback is used to provide the same functionality as the +text_to_glyphs callback does (see cairo_user_scaled_font_text_to_glyphs_func_t) +but has much less control on the output, +in exchange for increased ease of use. The inherent assumption to using +this callback is that each character maps to one glyph, and that the +mapping is context independent. It also assumes that glyphs are positioned +according to their advance width. These mean no ligatures, kerning, or +complex scripts can be implemented using this callback.

+

The callback is optional, and only used if text_to_glyphs callback is not +set or fails to return glyphs. If this callback is not set or if it returns +CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTED, an identity mapping from Unicode +code-points to glyph indices is assumed.

+

Note: While cairo does not impose any limitation on glyph indices, +some applications may assume that a glyph index fits in a 16-bit +unsigned integer. As such, it is advised that user-fonts keep their +glyphs in the 0 to 65535 range. Furthermore, some applications may +assume that glyph 0 is a special glyph-not-found glyph. User-fonts +are advised to use glyph 0 for such purposes and do not use that +glyph value for other purposes.

Description

+

Cairo has a three-part version number scheme. In this scheme, we use +even vs. odd numbers to distinguish fixed points in the software +vs. in-progress development, (such as from git instead of a tar file, +or as a "snapshot" tar file as opposed to a "release" tar file).

+
+ _____ Major. Always 1, until we invent a new scheme.
+/  ___ Minor. Even/Odd = Release/Snapshot (tar files) or Branch/Head (git)
+| /  _ Micro. Even/Odd = Tar-file/git
+| | /
+1.0.0
+
+

Here are a few examples of versions that one might see.

+
+Releases
+--------
+1.0.0 - A major release
+1.0.2 - A subsequent maintenance release
+1.2.0 - Another major release
+ 
+Snapshots
+---------
+1.1.2 - A snapshot (working toward the 1.2.0 release)
+ 
+In-progress development (eg. from git)
+--------------------------------------
+1.0.1 - Development on a maintenance branch (toward 1.0.2 release)
+1.1.1 - Development on head (toward 1.1.2 snapshot and 1.2.0 release)
+
+
+

Compatibility

+ +The API/ABI compatibility guarantees for various versions are as +follows. First, let's assume some cairo-using application code that is +successfully using the API/ABI "from" one version of cairo. Then let's +ask the question whether this same code can be moved "to" the API/ABI +of another version of cairo. + +Moving from a release to any later version (release, snapshot, +development) is always guaranteed to provide compatibility. + +Moving from a snapshot to any later version is not guaranteed to +provide compatibility, since snapshots may introduce new API that ends +up being removed before the next release. + +Moving from an in-development version (odd micro component) to any +later version is not guaranteed to provide compatibility. In fact, +there's not even a guarantee that the code will even continue to work +with the same in-development version number. This is because these +numbers don't correspond to any fixed state of the software, but +rather the many states between snapshots and releases. + +
+
+
+

Examining the version

+ +Cairo provides the ability to examine the version at either +compile-time or run-time and in both a human-readable form as well as +an encoded form suitable for direct comparison. Cairo also provides the +macro CAIRO_VERSION_ENCODE() to perform the encoding. + +
+Compile-time
+------------
+CAIRO_VERSION_STRING    Human-readable
+CAIRO_VERSION           Encoded, suitable for comparison
+ 
+Run-time
+--------
+cairo_version_string()  Human-readable
+cairo_version()         Encoded, suitable for comparison
+
+ +For example, checking that the cairo version is greater than or equal +to 1.0.0 could be achieved at compile-time or run-time as follows: + +
+##if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(1, 0, 0)
+printf ("Compiling with suitable cairo version: %s\n", %CAIRO_VERSION_STRING);
+##endif
+
+if (cairo_version() >= CAIRO_VERSION_ENCODE(1, 0, 0))
+    printf ("Running with suitable cairo version: %s\n", cairo_version_string ());
+
+
+
+
+

Functions

+
+

CAIRO_VERSION_ENCODE()

+
#define             CAIRO_VERSION_ENCODE(major, minor, micro)
+

This macro encodes the given cairo version into an integer. The numbers +returned by CAIRO_VERSION and cairo_version() are encoded using this macro. +Two encoded version numbers can be compared as integers. The encoding ensures +that later versions compare greater than earlier versions.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

major

the major component of the version number

 

minor

the minor component of the version number

 

micro

the micro component of the version number

 
+
+
+

Returns

+

the encoded version.

+

+
+

Since 1.0

+
+
+
+

CAIRO_VERSION_STRINGIZE()

+
#define             CAIRO_VERSION_STRINGIZE(major, minor, micro)
+

This macro encodes the given cairo version into an string. The numbers +returned by CAIRO_VERSION_STRING and cairo_version_string() are encoded using this macro. +The parameters to this macro must expand to numerical literals.

+

A run-time comparison to check that cairo's version is greater than +or equal to version X.Y.Z could be performed as follows:

+
+if (cairo_version() >= CAIRO_VERSION_ENCODE(X,Y,Z)) {...}
+
+

See also cairo_version_string() as well as the compile-time +equivalents CAIRO_VERSION and CAIRO_VERSION_STRING.

Creates a cairo surface that targets the given DC. The DC will be +queried for its initial clip extents, and this will be used as the +size of the cairo surface. The DC should be a printing DC; +antialiasing will be ignored, and GDI will be used as much as +possible to draw to the surface.

+

The returned surface will be wrapped using the paginated surface to +provide correct complex rendering behaviour; cairo_surface_show_page() and +associated methods must be used for correct output.

+
+

Parameters

+
+++++ + + + + + +

hdc

the DC to create a surface for

 
+
+
+

Returns

+

the newly created surface

+

+

cairo_win32_surface_get_dc ()

+
HDC
+cairo_win32_surface_get_dc (cairo_surface_t *surface);
+

Returns the HDC associated with this surface, or NULL if none. +Also returns NULL if the surface is not a win32 surface.

+

A call to cairo_surface_flush() is required before using the HDC to +ensure that all pending drawing operations are finished and to +restore any temporary modification cairo has made to its state. A +call to cairo_surface_mark_dirty() is required after the state or +the content of the HDC has been modified.

Description

+

The XCB surface is used to render cairo graphics to X Window System +windows and pixmaps using the XCB library.

+

Note that the XCB surface automatically takes advantage of the X render +extension if it is available.

+
+
+

Functions

+
+

cairo_xcb_surface_create ()

+
cairo_surface_t *
+cairo_xcb_surface_create (xcb_connection_t *connection,
+                          xcb_drawable_t drawable,
+                          xcb_visualtype_t *visual,
+                          int width,
+                          int height);
+

Creates an XCB surface that draws to the given drawable. +The way that colors are represented in the drawable is specified +by the provided visual.

+

Note: If drawable + is a Window, then the function +cairo_xcb_surface_set_size() must be called whenever the size of the +window changes.

+

When drawable + is a Window containing child windows then drawing to +the created surface will be clipped by those child windows. When +the created surface is used as a source, the contents of the +children will be included.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + +

connection

an XCB connection

 

drawable

an XCB drawable

 

visual

the visual to use for drawing to drawable +. The depth +of the visual must match the depth of the drawable. +Currently, only TrueColor visuals are fully supported.

 

width

the current width of drawable +

 

height

the current height of drawable +

 
+
+
+

Returns

+

a pointer to the newly created surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if an error such as out of memory +occurs. You can use cairo_surface_status() to check for this.

+

+                            int height);
+

Informs cairo of the new size of the XCB drawable underlying the +surface. For a surface created for a window (rather than a pixmap), +this function must be called each time the size of the window +changes. (For a subwindow, you are normally resizing the window +yourself, but for a toplevel window, it is necessary to listen for +ConfigureNotify events.)

+

A pixmap can never change size, so it is never necessary to call +this function on a surface created for a pixmap.

Description

+

Devices are the abstraction Cairo employs for the rendering system +used by a cairo_surface_t. You can get the device of a surface using +cairo_surface_get_device().

+

Devices are created using custom functions specific to the rendering +system you want to use. See the documentation for the surface types +for those functions.

+

An important function that devices fulfill is sharing access to the +rendering system between Cairo and your application. If you want to +access a device directly that you used to draw to with Cairo, you must +first call cairo_device_flush() to ensure that Cairo finishes all +operations on the device and resets it to a clean state.

+

Cairo also provides the functions cairo_device_acquire() and +cairo_device_release() to synchronize access to the rendering system +in a multithreaded environment. This is done internally, but can also +be used by applications.

+

Putting this all together, a function that works with devices should +look something like this:

+
+void
+my_device_modifying_function (cairo_device_t *device)
+{
+  cairo_status_t status;
+
+  // Ensure the device is properly reset
+  cairo_device_flush (device);
+  // Try to acquire the device
+  status = cairo_device_acquire (device);
+  if (status != CAIRO_STATUS_SUCCESS) {
+    printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status));
+    return;
+  }
+
+  // Do the custom operations on the device here.
+  // But do not call any Cairo functions that might acquire devices.
+  
+  // Release the device when done.
+  cairo_device_release (device);
+}
+
+

Please refer to the documentation of each backend for +additional usage requirements, guarantees provided, and +interactions with existing surface API of the device functions for +surfaces of that type. +

+
+
+

Functions

+
+

cairo_device_reference ()

+
cairo_device_t *
+cairo_device_reference (cairo_device_t *device);
+

Increases the reference count on device + by one. This prevents +device + from being destroyed until a matching call to +cairo_device_destroy() is made.

+

The number of references to a cairo_device_t can be get using +cairo_device_get_reference_count().

+
+

Parameters

+
+++++ + + + + + +

device

a cairo_device_t

 
+
+
+

Returns

+

the referenced cairo_device_t.

+

+
+

Since 1.10

+
+
+
+

cairo_device_destroy ()

+
void
+cairo_device_destroy (cairo_device_t *device);
+

Decreases the reference count on device + by one. If the result is +zero, then device + and all associated resources are freed. See +cairo_device_reference().

+

This function may acquire devices if the last reference was dropped.

+
+

Parameters

+
+++++ + + + + + +

device

a cairo_device_t

 
+
+

Since 1.10

+
+
+
+

cairo_device_status ()

+
cairo_status_t
+cairo_device_status (cairo_device_t *device);
+

Checks whether an error has previously occurred for this +device.

+
+

Parameters

+
+++++ + + + + + +

device

a cairo_device_t

 
+
+
+

Returns

+

CAIRO_STATUS_SUCCESS on success or an error code if +the device is in an error state.

+

+
+

Since 1.10

+
+
+
+

cairo_device_finish ()

+
void
+cairo_device_finish (cairo_device_t *device);
+

This function finishes the device and drops all references to +external resources. All surfaces, fonts and other objects created +for this device + will be finished, too. +Further operations on the device + will not affect the device + but +will instead trigger a CAIRO_STATUS_DEVICE_FINISHED error.

+

When the last call to cairo_device_destroy() decreases the +reference count to zero, cairo will call cairo_device_finish() if +it hasn't been called already, before freeing the resources +associated with the device.

+

This function may acquire devices.

+
+

Parameters

+
+++++ + + + + + +

device

the cairo_device_t to finish

 
+
+

Since 1.10

+
+
+
+

cairo_device_flush ()

+
void
+cairo_device_flush (cairo_device_t *device);
+

Finish any pending operations for the device and also restore any +temporary modifications cairo has made to the device's state. +This function must be called before switching from using the +device with Cairo to operating on it directly with native APIs. +If the device doesn't support direct access, then this function +does nothing.

+

This function may acquire devices.

+
+

Parameters

+
+++++ + + + + + +

device

a cairo_device_t

 
+
+

+                            const cairo_user_data_key_t *key);
+

Return user data previously attached to device + using the +specified key. If no user data has been attached with the given +key this function returns NULL.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

device

a cairo_device_t

 

key

the address of the cairo_user_data_key_t the user data was +attached to

cairo_device_acquire ()

+
cairo_status_t
+cairo_device_acquire (cairo_device_t *device);
+

Acquires the device + for the current thread. This function will block +until no other thread has acquired the device.

+

If the return value is CAIRO_STATUS_SUCCESS, you successfully acquired the +device. From now on your thread owns the device and no other thread will be +able to acquire it until a matching call to cairo_device_release(). It is +allowed to recursively acquire the device multiple times from the same +thread.

+

You must never acquire two different devices at the same time +unless this is explicitly allowed. Otherwise the possibility of deadlocks +exist. + +As various Cairo functions can acquire devices when called, these functions +may also cause deadlocks when you call them with an acquired device. So you +must not have a device acquired when calling them. These functions are +marked in the documentation. +

+
+

Parameters

+
+++++ + + + + + +

device

a cairo_device_t

 
+
+
+

Returns

+

CAIRO_STATUS_SUCCESS on success or an error code if +the device is in an error state and could not be +acquired. After a successful call to cairo_device_acquire(), +a matching call to cairo_device_release() is required.

Types and Values

+
+

cairo_device_t

+
typedef struct _cairo_device cairo_device_t;
+
+

A cairo_device_t represents the driver interface for drawing +operations to a cairo_surface_t. There are different subtypes of +cairo_device_t for different drawing backends; for example, +cairo_egl_device_create() creates a device that wraps an EGL display and +context.

+

The type of a device can be queried with cairo_device_get_type().

+

Memory management of cairo_device_t is done with +cairo_device_reference() and cairo_device_destroy().

+

Since 1.10

+
+
+
+

enum cairo_device_type_t

+

cairo_device_type_t is used to describe the type of a given +device. The devices types are also known as "backends" within cairo.

+

The device type can be queried with cairo_device_get_type()

+

The various cairo_device_t functions can be used with devices of +any type, but some backends also provide type-specific functions +that must only be called with a device of the appropriate +type. These functions have names that begin with +cairo_type_device such as +cairo_xcb_device_debug_cap_xrender_version().

+

The behavior of calling a type-specific function with a device of +the wrong type is undefined.

+

New entries may be added in future versions.

Description

+

cairo_font_face_t represents a particular font at a particular weight, +slant, and other characteristic but no size, transformation, or size.

+

Font faces are created using font-backend-specific +constructors, typically of the form +cairo_backend_font_face_create(), +or implicitly using the toy text API by way of +cairo_select_font_face(). The resulting face can be accessed using +cairo_get_font_face().

+
+
+

Functions

+
+

cairo_font_face_reference ()

+
cairo_font_face_t *
+cairo_font_face_reference (cairo_font_face_t *font_face);
+

Increases the reference count on font_face + by one. This prevents +font_face + from being destroyed until a matching call to +cairo_font_face_destroy() is made.

+

The number of references to a cairo_font_face_t can be get using +cairo_font_face_get_reference_count().

+

Types and Values

+
+

cairo_font_face_t

+
typedef struct _cairo_font_face cairo_font_face_t;
+
+

A cairo_font_face_t specifies all aspects of a font other +than the size or font matrix (a font matrix is used to distort +a font by sheering it or scaling it unequally in the two +directions) . A font face can be set on a cairo_t by using +cairo_set_font_face(); the size and font matrix are set with +cairo_set_font_size() and cairo_set_font_matrix().

+

There are various types of font faces, depending on the +font backend they use. The type of a +font face can be queried using cairo_font_face_get_type().

+

Memory management of cairo_font_face_t is done with +cairo_font_face_reference() and cairo_font_face_destroy().

+

Since 1.0

+
+
+
+

enum cairo_font_type_t

+

cairo_font_type_t is used to describe the type of a given font +face or scaled font. The font types are also known as "font +backends" within cairo.

+

The type of a font face is determined by the function used to +create it, which will generally be of the form +cairo_type_font_face_create(). +The font face type can be queried with cairo_font_face_get_type()

+

The various cairo_font_face_t functions can be used with a font face +of any type.

+

The type of a scaled font is determined by the type of the font +face passed to cairo_scaled_font_create(). The scaled font type can +be queried with cairo_scaled_font_get_type()

+

The various cairo_scaled_font_t functions can be used with scaled +fonts of any type, but some font backends also provide +type-specific functions that must only be called with a scaled font +of the appropriate type. These functions have names that begin with +cairo_type_scaled_font() +such as cairo_ft_scaled_font_lock_face().

+

The behavior of calling a type-specific function with a scaled font +of the wrong type is undefined.

+

New entries may be added in future versions.

Description

+

The font options specify how fonts should be rendered. Most of the +time the font options implied by a surface are just right and do not +need any changes, but for pixel-based targets tweaking font options +may result in superior output on a particular display.

cairo_matrix_t is used throughout cairo to convert between different +coordinate spaces. A cairo_matrix_t holds an affine transformation, +such as a scale, rotation, shear, or a combination of these. +The transformation of a point (x,y) +is given by:

+
+x_new = xx * x + xy * y + x0;
+y_new = yx * x + yy * y + y0;
+
+

The current transformation matrix of a cairo_t, represented as a +cairo_matrix_t, defines the transformation from user-space +coordinates to device-space coordinates. See cairo_get_matrix() and +cairo_set_matrix().

void
+cairo_matrix_transform_distance (const cairo_matrix_t *matrix,

+                                 double *dy);
+

Transforms the distance vector (dx +,dy +) by matrix +. This is +similar to cairo_matrix_transform_point() except that the translation +components of the transformation are ignored. The calculation of +the returned vector is as follows:

+
+dx2 = dx1 * a + dy1 * c;
+dy2 = dx1 * b + dy1 * d;
+
+

Affine transformations are position invariant, so the same vector +always transforms to the same vector. If (x1 +,y1 +) transforms +to (x2 +,y2 +) then (x1 ++dx1 +,y1 ++dy1 +) will transform to +(x1 ++dx2 +,y1 ++dy2 +) for all values of x1 + and x2 +.

Description

+

cairo_pattern_t is the paint with which cairo draws. +The primary use of patterns is as the source for all cairo drawing +operations, although they can also be used as masks, that is, as the +brush too.

+

A cairo pattern is created by using one of the many constructors, +of the form +cairo_pattern_create_type() +or implicitly through +cairo_set_source_type() +functions.

+
+
+

Functions

+
+

cairo_pattern_add_color_stop_rgb ()

+
void
+cairo_pattern_add_color_stop_rgb (cairo_pattern_t *pattern,
+                                  double offset,
+                                  double red,
+                                  double green,
+                                  double blue);
+

Adds an opaque color stop to a gradient pattern. The offset +specifies the location along the gradient's control vector. For +example, a linear gradient's control vector is from (x0,y0) to +(x1,y1) while a radial gradient's control vector is from any point +on the start circle to the corresponding point on the end circle.

+

The color is specified in the same way as in cairo_set_source_rgb().

+

If two (or more) stops are specified with identical offset values, +they will be sorted according to the order in which the stops are +added, (stops added earlier will compare less than stops added +later). This can be useful for reliably making sharp color +transitions instead of the typical blend.

+

Note: If the pattern is not a gradient pattern, (eg. a linear or +radial pattern), then the pattern will be put into an error status +with a status of CAIRO_STATUS_PATTERN_TYPE_MISMATCH.

+

+                                   double alpha);
+

Adds a translucent color stop to a gradient pattern. The offset +specifies the location along the gradient's control vector. For +example, a linear gradient's control vector is from (x0,y0) to +(x1,y1) while a radial gradient's control vector is from any point +on the start circle to the corresponding point on the end circle.

+

The color is specified in the same way as in cairo_set_source_rgba().

cairo_pattern_create_mesh ()

+
cairo_pattern_t *
+cairo_pattern_create_mesh (void);
+

Create a new mesh pattern.

+

Mesh patterns are tensor-product patch meshes (type 7 shadings in +PDF). Mesh patterns may also be used to create other types of +shadings that are special cases of tensor-product patch meshes such +as Coons patch meshes (type 6 shading in PDF) and Gouraud-shaded +triangle meshes (type 4 and 5 shadings in PDF).

+

Mesh patterns consist of one or more tensor-product patches, which +should be defined before using the mesh pattern. Using a mesh +pattern with a partially defined patch as source or mask will put +the context in an error status with a status of +CAIRO_STATUS_INVALID_MESH_CONSTRUCTION.

+

A tensor-product patch is defined by 4 Bézier curves (side 0, 1, 2, +3) and by 4 additional control points (P0, P1, P2, P3) that provide +further control over the patch and complete the definition of the +tensor-product patch. The corner C0 is the first point of the +patch.

+

Degenerate sides are permitted so straight lines may be used. A +zero length line on one side may be used to create 3 sided patches.

+
+      C1     Side 1       C2
+       +---------------+
+       |               |
+       |  P1       P2  |
+       |               |
+Side 0 |               | Side 2
+       |               |
+       |               |
+       |  P0       P3  |
+       |               |
+       +---------------+
+     C0     Side 3        C3
+
+

Each patch is constructed by first calling +cairo_mesh_pattern_begin_patch(), then cairo_mesh_pattern_move_to() +to specify the first point in the patch (C0). Then the sides are +specified with calls to cairo_mesh_pattern_curve_to() and +cairo_mesh_pattern_line_to().

+

The four additional control points (P0, P1, P2, P3) in a patch can +be specified with cairo_mesh_pattern_set_control_point().

+

At each corner of the patch (C0, C1, C2, C3) a color may be +specified with cairo_mesh_pattern_set_corner_color_rgb() or +cairo_mesh_pattern_set_corner_color_rgba(). Any corner whose color +is not explicitly specified defaults to transparent black.

+

A Coons patch is a special case of the tensor-product patch where +the control points are implicitly defined by the sides of the +patch. The default value for any control point not specified is the +implicit value for a Coons patch, i.e. if no control points are +specified the patch is a Coons patch.

+

A triangle is a special case of the tensor-product patch where the +control points are implicitly defined by the sides of the patch, +all the sides are lines and one of them has length 0, i.e. if the +patch is specified using just 3 lines, it is a triangle. If the +corners connected by the 0-length side have the same color, the +patch is a Gouraud-shaded triangle.

+

Patches may be oriented differently to the above diagram. For +example the first point could be at the top left. The diagram only +shows the relationship between the sides, corners and control +points. Regardless of where the first point is located, when +specifying colors, corner 0 will always be the first point, corner +1 the point between side 0 and side 1 etc.

+

Calling cairo_mesh_pattern_end_patch() completes the current +patch. If less than 4 sides have been defined, the first missing +side is defined as a line from the current point to the first point +of the patch (C0) and the other sides are degenerate lines from C0 +to C0. The corners between the added sides will all be coincident +with C0 of the patch and their color will be set to be the same as +the color of C0.

+

Additional patches may be added with additional calls to +cairo_mesh_pattern_begin_patch()/cairo_mesh_pattern_end_patch().

+
+cairo_pattern_t *pattern = cairo_pattern_create_mesh ();
+
+/* Add a Coons patch */
+cairo_mesh_pattern_begin_patch (pattern);
+cairo_mesh_pattern_move_to (pattern, 0, 0);

+cairo_mesh_pattern_curve_to (pattern, 60,  70,  30, 130,   0, 100);
+cairo_mesh_pattern_curve_to (pattern, 30,  70, -30,  30,   0, 0);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 0, 1, 0, 0);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 1, 0, 1, 0);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 2, 0, 0, 1);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 3, 1, 1, 0);
+cairo_mesh_pattern_end_patch (pattern);
+
+/* Add a Gouraud-shaded triangle */
+cairo_mesh_pattern_begin_patch (pattern)
+cairo_mesh_pattern_move_to (pattern, 100, 100);
+cairo_mesh_pattern_line_to (pattern, 130, 130);
+cairo_mesh_pattern_line_to (pattern, 130,  70);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 0, 1, 0, 0);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 1, 0, 1, 0);
+cairo_mesh_pattern_set_corner_color_rgb (pattern, 2, 0, 0, 1);
+cairo_mesh_pattern_end_patch (pattern)
+
+

When two patches overlap, the last one that has been added is drawn +over the first one.

+

When a patch folds over itself, points are sorted depending on +their parameter coordinates inside the patch. The v coordinate +ranges from 0 to 1 when moving from side 3 to side 1; the u +coordinate ranges from 0 to 1 when going from side 0 to side

+

  1. Points with higher v coordinate hide points with lower v +coordinate. When two points have the same v coordinate, the one +with higher u coordinate is above. This means that points nearer to +side 1 are above points nearer to side 3; when this is not +sufficient to decide which point is above (for example when both +points belong to side 1 or side 3) points nearer to side 2 are +above points nearer to side 0.

+

For a complete definition of tensor-product patches, see the PDF +specification (ISO32000), which describes the parametrization in +detail.

+

Note: The coordinates are always in pattern space. For a new +pattern, pattern space is identical to user space, but the +relationship between the spaces can be changed with +cairo_pattern_set_matrix().

+
+

Returns

+

the newly created cairo_pattern_t if successful, or +an error pattern in case of no memory. The caller owns the returned +object and should call cairo_pattern_destroy() when finished with +it.

+

This function will always return a valid pointer, but if an error +occurred the pattern status will be set to an error. To inspect the +status of a pattern use cairo_pattern_status().

+
void
+cairo_pattern_set_filter (cairo_pattern_t *pattern,
+                          cairo_filter_t filter);
+

Sets the filter to be used for resizing when using this pattern. +See cairo_filter_t for details on each filter.

+

  • Note that you might want to control filtering even when you do not +have an explicit cairo_pattern_t object, (for example when using +cairo_set_source_surface()). In these cases, it is convenient to +use cairo_get_source() to get access to the pattern that cairo +creates implicitly. For example:

+
+cairo_set_source_surface (cr, image, x, y);
+cairo_pattern_set_filter (cairo_get_source (cr), CAIRO_FILTER_NEAREST);
+
+
+

Parameters

+
+++++ + + + + + + + + + + + + +

pattern

a cairo_pattern_t

 

filter

a cairo_filter_t describing the filter to use for resizing +the pattern

+
+
+

cairo_pattern_get_filter ()

+
cairo_filter_t
+cairo_pattern_get_filter (cairo_pattern_t *pattern);
+

+
+

Parameters

+
+++++ + + + + + +

pattern

a cairo_pattern_t

 
+
+
+

Returns

+

the current filter used for resizing the pattern.

cairo_pattern_set_matrix ()

+
void
+cairo_pattern_set_matrix (cairo_pattern_t *pattern,
+                          const cairo_matrix_t *matrix);
+

Sets the pattern's transformation matrix to matrix +. This matrix is +a transformation from user space to pattern space.

+

When a pattern is first created it always has the identity matrix +for its transformation matrix, which means that pattern space is +initially identical to user space.

+

Important: Please note that the direction of this transformation +matrix is from user space to pattern space. This means that if you +imagine the flow from a pattern to user space (and on to device +space), then coordinates in that flow will be transformed by the +inverse of the pattern matrix.

+

For example, if you want to make a pattern appear twice as large as +it does by default the correct code to use is:

+
+cairo_matrix_init_scale (&matrix, 0.5, 0.5);
+cairo_pattern_set_matrix (pattern, &matrix);
+
+

Meanwhile, using values of 2.0 rather than 0.5 in the code above +would cause the pattern to appear at half of its default size.

+

Also, please note the discussion of the user-space locking +semantics of cairo_set_source().

+
+

Types and Values

+
+

cairo_pattern_t

+
typedef struct _cairo_pattern cairo_pattern_t;
+
+

A cairo_pattern_t represents a source when drawing onto a +surface. There are different subtypes of cairo_pattern_t, +for different types of sources; for example, +cairo_pattern_create_rgb() creates a pattern for a solid +opaque color.

+

Other than various +cairo_pattern_create_type() +functions, some of the pattern types can be implicitly created using various +cairo_set_source_type() functions; +for example cairo_set_source_rgb().

+

The type of a pattern can be queried with cairo_pattern_get_type().

+

Memory management of cairo_pattern_t is done with +cairo_pattern_reference() and cairo_pattern_destroy().

+

Since 1.0

+
+
+
+

enum cairo_extend_t

+

cairo_extend_t is used to describe how pattern color/alpha will be +determined for areas "outside" the pattern's natural area, (for +example, outside the surface bounds or outside the gradient +geometry).

+

Mesh patterns are not affected by the extend mode.

+

The default extend mode is CAIRO_EXTEND_NONE for surface patterns +and CAIRO_EXTEND_PAD for gradient patterns.

+

New entries may be added in future versions.

+
+

Members

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

CAIRO_EXTEND_NONE

 +

pixels outside of the source pattern + are fully transparent (Since 1.0)

+		 

CAIRO_EXTEND_REPEAT

 +

the pattern is tiled by repeating (Since 1.0)

+		 

CAIRO_EXTEND_REFLECT

 +

the pattern is tiled by reflecting + at the edges (Since 1.0; but only implemented for surface patterns since 1.6)

+		 

CAIRO_EXTEND_PAD

 +

pixels outside of the pattern copy + the closest pixel from the source (Since 1.2; but only + implemented for surface patterns since 1.6)

+		 
+
+

Since 1.0

+
+
+
+

enum cairo_filter_t

+

cairo_filter_t is used to indicate what filtering should be +applied when reading pixel values from patterns. See +cairo_pattern_set_filter() for indicating the desired filter to be +used with a particular pattern.

+
+

+		 
+
+

Since 1.0

+
+
+
+

enum cairo_pattern_type_t

+

cairo_pattern_type_t is used to describe the type of a given pattern.

+

The type of a pattern is determined by the function used to create +it. The cairo_pattern_create_rgb() and cairo_pattern_create_rgba() +functions create SOLID patterns. The remaining +cairo_pattern_create functions map to pattern types in obvious +ways.

+

The pattern type can be queried with cairo_pattern_get_type()

+

Most cairo_pattern_t functions can be called with a pattern of any +type, (though trying to change the extend or filter for a solid +pattern will have no effect). A notable exception is +cairo_pattern_add_color_stop_rgb() and +cairo_pattern_add_color_stop_rgba() which must only be called with +gradient patterns (either LINEAR or RADIAL). Otherwise the pattern +will be shutdown and put into an error state.

+

New entries may be added in future versions.

Increases the reference count on scaled_font + by one. This prevents +scaled_font + from being destroyed until a matching call to +cairo_scaled_font_destroy() is made.

+

The number of references to a cairo_scaled_font_t can be get using +cairo_scaled_font_get_reference_count().

+
+

Parameters

Checks whether an error has previously occurred for this +scaled_font.

+
+

Parameters

+
+++++ + + + + + +

scaled_font

cairo_scaled_font_text_extents ()

void
+cairo_scaled_font_text_extents (cairo_scaled_font_t *scaled_font,
+                                const char *utf8,
+                                cairo_text_extents_t *extents);
+

Gets the extents for a string of text. The extents describe a +user-space rectangle that encloses the "inked" portion of the text +drawn at the origin (0,0) (as it would be drawn by cairo_show_text() +if the cairo graphics state were set to the same font_face, +font_matrix, ctm, and font_options as scaled_font +). Additionally, +the x_advance and y_advance values indicate the amount by which the +current point would be advanced by cairo_show_text().

+

Note that whitespace characters do not directly contribute to the +size of the rectangle (extents.width and extents.height). They do +contribute indirectly by changing the position of non-whitespace +characters. In particular, trailing whitespace characters are +likely to not affect the size of the rectangle, though they will +affect the x_advance and y_advance values.

+
+

Parameters

+

Gets the extents for an array of glyphs. The extents describe a +user-space rectangle that encloses the "inked" portion of the +glyphs, (as they would be drawn by cairo_show_glyphs() if the cairo +graphics state were set to the same font_face, font_matrix, ctm, +and font_options as scaled_font +). Additionally, the x_advance and +y_advance values indicate the amount by which the current point +would be advanced by cairo_show_glyphs().

+                                  cairo_text_cluster_flags_t *cluster_flags);
+

Converts UTF-8 text to an array of glyphs, optionally with cluster +mapping, that can be used to render later using scaled_font +.

+

If glyphs + initially points to a non-NULL value, that array is used +as a glyph buffer, and num_glyphs + should point to the number of glyph +entries available there. If the provided glyph array is too short for +the conversion, a new glyph array is allocated using cairo_glyph_allocate() +and placed in glyphs +. Upon return, num_glyphs + always contains the +number of generated glyphs. If the value glyphs + points to has changed +after the call, the user is responsible for freeing the allocated glyph +array using cairo_glyph_free(). This may happen even if the provided +array was large enough.

+

If clusters + is not NULL, num_clusters + and cluster_flags + should not be NULL, +and cluster mapping will be computed. +The semantics of how cluster array allocation works is similar to the glyph +array. That is, +if clusters + initially points to a non-NULL value, that array is used +as a cluster buffer, and num_clusters + should point to the number of cluster +entries available there. If the provided cluster array is too short for +the conversion, a new cluster array is allocated using cairo_text_cluster_allocate() +and placed in clusters +. Upon return, num_clusters + always contains the +number of generated clusters. If the value clusters + points at has changed +after the call, the user is responsible for freeing the allocated cluster +array using cairo_text_cluster_free(). This may happen even if the provided +array was large enough.

+

In the simplest case, glyphs + and clusters + can point to NULL initially +and a suitable array will be allocated. In code:

+
+cairo_status_t status;
+
+cairo_glyph_t *glyphs = NULL;
+int num_glyphs;
+cairo_text_cluster_t *clusters = NULL;
+int num_clusters;
+cairo_text_cluster_flags_t cluster_flags;
+
+status = cairo_scaled_font_text_to_glyphs (scaled_font,
+                                           x, y,
+                                           utf8, utf8_len,
+                                           &glyphs, &num_glyphs,
+                                           &clusters, &num_clusters, &cluster_flags);
+
+if (status == CAIRO_STATUS_SUCCESS) {
+    cairo_show_text_glyphs (cr,
+                            utf8, utf8_len,
+                            glyphs, num_glyphs,
+                            clusters, num_clusters, cluster_flags);
+
+    cairo_glyph_free (glyphs);
+    cairo_text_cluster_free (clusters);
+}
+
+

If no cluster mapping is needed:

+
+cairo_status_t status;
+
+cairo_glyph_t *glyphs = NULL;
+int num_glyphs;
+
+status = cairo_scaled_font_text_to_glyphs (scaled_font,

+                                           &glyphs, &num_glyphs,
+                                           NULL, NULL,

+if (status == CAIRO_STATUS_SUCCESS) {
+    cairo_show_glyphs (cr, glyphs, num_glyphs);
+    cairo_glyph_free (glyphs);
+}
+
+

If stack-based glyph and cluster arrays are to be used for small +arrays:

+
+cairo_status_t status;
+
+cairo_glyph_t stack_glyphs[40];
+cairo_glyph_t *glyphs = stack_glyphs;
+int num_glyphs = sizeof (stack_glyphs) / sizeof (stack_glyphs[0]);

+status = cairo_scaled_font_text_to_glyphs (scaled_font,

For details of how clusters +, num_clusters +, and cluster_flags + map input +UTF-8 text to the output glyphs see cairo_show_text_glyphs().

Types and Values

+
+

cairo_scaled_font_t

+
typedef struct _cairo_scaled_font cairo_scaled_font_t;
+
+

A cairo_scaled_font_t is a font scaled to a particular size and device +resolution. A cairo_scaled_font_t is most useful for low-level font +usage where a library or application wants to cache a reference +to a scaled font to speed up the computation of metrics.

+

There are various types of scaled fonts, depending on the +font backend they use. The type of a +scaled font can be queried using cairo_scaled_font_get_type().

+

Memory management of cairo_scaled_font_t is done with +cairo_scaled_font_reference() and cairo_scaled_font_destroy().

+    double descent;
+    double height;
+    double max_x_advance;
+    double max_y_advance;
+} cairo_font_extents_t;
+
+

The cairo_font_extents_t structure stores metric information for +a font. Values are given in the current user-space coordinate +system.

+

Because font metrics are in user-space coordinates, they are +mostly, but not entirely, independent of the current transformation +matrix. If you call cairo_scale(cr, 2.0, 2.0), +text will be drawn twice as big, but the reported text extents will +not be doubled. They will change slightly due to hinting (so you +can't assume that metrics are independent of the transformation +matrix), but otherwise will remain unchanged.

double ascent;

the distance that the font extends above the baseline. +Note that this is not always exactly equal to the maximum +of the extents of all the glyphs in the font, but rather +is picked to express the font designer's intent as to +how the font should align with elements above it.

 

double descent;

the distance that the font extends below the baseline. +This value is positive for typical fonts that include +portions below the baseline. Note that this is not always +exactly equal to the maximum of the extents of all the +glyphs in the font, but rather is picked to express the +font designer's intent as to how the font should +align with elements below it.

 

double height;

the recommended vertical distance between baselines when +setting consecutive lines of text with the font. This +is greater than ascent ++descent +by a +quantity known as the line spacing +or external leading. When space +is at a premium, most fonts can be set with only +a distance of ascent ++descent +between lines.

 

double max_x_advance;

the maximum distance in the X direction that +the origin is advanced for any glyph in the font.

 

double max_y_advance;

the maximum distance in the Y direction that +the origin is advanced for any glyph in the font. +This will be zero for normal fonts used for horizontal +writing. (The scripts of East Asia are sometimes written +vertically.)

+    double y_advance;
+} cairo_text_extents_t;
+
+

The cairo_text_extents_t structure stores the extents of a single +glyph or a string of glyphs in user-space coordinates. Because text +extents are in user-space coordinates, they are mostly, but not +entirely, independent of the current transformation matrix. If you call +cairo_scale(cr, 2.0, 2.0), text will +be drawn twice as big, but the reported text extents will not be +doubled. They will change slightly due to hinting (so you can't +assume that metrics are independent of the transformation matrix), +but otherwise will remain unchanged.

double y_bearing;

the vertical distance from the origin to the +topmost part of the glyphs as drawn. Positive only if the +glyphs lie completely below the origin; will usually be +negative.

 

double width;

width of the glyphs as drawn

Object Hierarchy

+
+
+

Description

+

cairo_surface_t is the abstract type representing all different drawing +targets that cairo can render to. The actual drawings are +performed using a cairo context.

+

A cairo surface is created by using backend-specific +constructors, typically of the form +cairo_backend_surface_create().

+

Most surface types allow accessing the surface without using Cairo +functions. If you do this, keep in mind that it is mandatory that you call +cairo_surface_flush() before reading from or writing to the surface and that +you must use cairo_surface_mark_dirty() after modifying it.

+
+

Example 1. Directly modifying an image surface

+
+void
+modify_image_surface (cairo_surface_t *surface)
+{
+  unsigned char *data;
+  int width, height, stride;
+
+  // flush to ensure all writing to the image was done
+  cairo_surface_flush (surface);
+
+  // modify the image
+  data = cairo_image_surface_get_data (surface);
+  width = cairo_image_surface_get_width (surface);
+  height = cairo_image_surface_get_height (surface);
+  stride = cairo_image_surface_get_stride (surface);
+  modify_image_data (data, width, height, stride);
+
+  // mark the image dirty so Cairo clears its caches.
+  cairo_surface_mark_dirty (surface);
+}
+
+
+

Note that for other surface types it might be necessary to acquire the +surface's device first. See cairo_device_acquire() for a discussion of +devices.

+
+
+

Functions

+
+

cairo_surface_create_similar ()

+
cairo_surface_t *
+cairo_surface_create_similar (cairo_surface_t *other,
+                              cairo_content_t content,
+                              int width,
+                              int height);
+

Create a new surface that is as compatible as possible with an +existing surface. For example the new surface will have the same +fallback resolution and font options as other +. Generally, the new +surface will also use the same backend as other +, unless that is +not possible for some reason. The type of the returned surface may +be examined with cairo_surface_get_type().

+

Initially the surface contents are all 0 (transparent if contents +have transparency, black otherwise.)

+

Use cairo_surface_create_similar_image() if you need an image surface +which can be painted quickly to the target surface.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

other

an existing surface used to select the backend of the new surface

 

content

the content for the new surface

 

width

width of the new surface, (in device-space units)

 

height

height of the new surface (in device-space units)

 
+
+
+

Returns

+

a pointer to the newly allocated surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if other +is already in an error state +or any other error occurs.

+

+
+

Since 1.0

+
+
+
+

cairo_surface_create_similar_image ()

+
cairo_surface_t *
+cairo_surface_create_similar_image (cairo_surface_t *other,
+                                    cairo_format_t format,
+                                    int width,
+                                    int height);
+

Create a new image surface that is as compatible as possible for uploading +to and the use in conjunction with an existing surface. However, this surface +can still be used like any normal image surface.

+

Initially the surface contents are all 0 (transparent if contents +have transparency, black otherwise.)

+

Use cairo_surface_create_similar() if you don't need an image surface.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

other

an existing surface used to select the preference of the new surface

 

format

the format for the new surface

 

width

width of the new surface, (in device-space units)

 

height

height of the new surface (in device-space units)

 
+
+
+

Returns

+

a pointer to the newly allocated image surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if other +is already in an error state +or any other error occurs.

+

+
+

Since 1.12

+
+
+
+

cairo_surface_create_for_rectangle ()

+
cairo_surface_t *
+cairo_surface_create_for_rectangle (cairo_surface_t *target,
+                                    double x,
+                                    double y,
+                                    double width,
+                                    double height);
+

Create a new surface that is a rectangle within the target surface. +All operations drawn to this surface are then clipped and translated +onto the target surface. Nothing drawn via this sub-surface outside of +its bounds is drawn onto the target surface, making this a useful method +for passing constrained child surfaces to library routines that draw +directly onto the parent surface, i.e. with no further backend allocations, +double buffering or copies.

+

The semantics of subsurfaces have not been finalized yet +unless the rectangle is in full device units, is contained within +the extents of the target surface, and the target or subsurface's +device transforms are not changed.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + +

target

an existing surface for which the sub-surface will point to

 

x

the x-origin of the sub-surface from the top-left of the target surface (in device-space units)

 

y

the y-origin of the sub-surface from the top-left of the target surface (in device-space units)

 

width

width of the sub-surface (in device-space units)

 

height

height of the sub-surface (in device-space units)

 
+
+
+

Returns

+

a pointer to the newly allocated surface. The caller +owns the surface and should call cairo_surface_destroy() when done +with it.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if other +is already in an error state +or any other error occurs.

+

+
+

Since 1.10

+
+
+
+

cairo_surface_reference ()

+
cairo_surface_t *
+cairo_surface_reference (cairo_surface_t *surface);
+

Increases the reference count on surface + by one. This prevents +surface + from being destroyed until a matching call to +cairo_surface_destroy() is made.

+

The number of references to a cairo_surface_t can be get using +cairo_surface_get_reference_count().

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+
+

Returns

+

the referenced cairo_surface_t.

+

+
+

Since 1.0

+
+
+
+

cairo_surface_destroy ()

+
void
+cairo_surface_destroy (cairo_surface_t *surface);
+

Decreases the reference count on surface + by one. If the result is +zero, then surface + and all associated resources are freed. See +cairo_surface_reference().

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+

Since 1.0

+
+
+
+

cairo_surface_status ()

+
cairo_status_t
+cairo_surface_status (cairo_surface_t *surface);
+

Checks whether an error has previously occurred for this +surface.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+
+

Returns

+

CAIRO_STATUS_SUCCESS, CAIRO_STATUS_NULL_POINTER, +CAIRO_STATUS_NO_MEMORY, CAIRO_STATUS_READ_ERROR, +CAIRO_STATUS_INVALID_CONTENT, CAIRO_STATUS_INVALID_FORMAT, or +CAIRO_STATUS_INVALID_VISUAL.

+

+
+

Since 1.0

+
+
+
+

cairo_surface_finish ()

+
void
+cairo_surface_finish (cairo_surface_t *surface);
+

This function finishes the surface and drops all references to +external resources. For example, for the Xlib backend it means +that cairo will no longer access the drawable, which can be freed. +After calling cairo_surface_finish() the only valid operations on a +surface are getting and setting user, referencing and +destroying, and flushing and finishing it. +Further drawing to the surface will not affect the +surface but will instead trigger a CAIRO_STATUS_SURFACE_FINISHED +error.

+

When the last call to cairo_surface_destroy() decreases the +reference count to zero, cairo will call cairo_surface_finish() if +it hasn't been called already, before freeing the resources +associated with the surface.

+
+

Parameters

+
+++++ + + + + + +

surface

the cairo_surface_t to finish

 
+
+

Since 1.0

+
+
+
+

cairo_surface_flush ()

+
void
+cairo_surface_flush (cairo_surface_t *surface);
+

Do any pending drawing for the surface and also restore any +temporary modifications cairo has made to the surface's +state. This function must be called before switching from +drawing on the surface with cairo to drawing on it directly +with native APIs. If the surface doesn't support direct access, +then this function does nothing.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+

Since 1.0

+
+
+
+

cairo_surface_get_device ()

+
cairo_device_t *
+cairo_surface_get_device (cairo_surface_t *surface);
+

This function returns the device for a surface +. +See cairo_device_t.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+
+

Returns

+

The device for surface +or NULL if the surface does +not have an associated device.

+

+
+

Since 1.10

+
+
+
+

cairo_surface_get_font_options ()

+
void
+cairo_surface_get_font_options (cairo_surface_t *surface,
+                                cairo_font_options_t *options);
+

Retrieves the default font rendering options for the surface. +This allows display surfaces to report the correct subpixel order +for rendering on them, print surfaces to disable hinting of +metrics and so forth. The result can then be used with +cairo_scaled_font_create().

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

surface

a cairo_surface_t

 

options

a cairo_font_options_t object into which to store +the retrieved options. All existing values are overwritten

 
+
+

Since 1.0

+
+
+
+

cairo_surface_get_content ()

+
cairo_content_t
+cairo_surface_get_content (cairo_surface_t *surface);
+

This function returns the content type of surface + which indicates +whether the surface contains color and/or alpha information. See +cairo_content_t.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+
+

Returns

+

The content type of surface +.

+

+
+

Since 1.2

+
+
+
+

cairo_surface_mark_dirty ()

+
void
+cairo_surface_mark_dirty (cairo_surface_t *surface);
+

Tells cairo that drawing has been done to surface using means other +than cairo, and that cairo should reread any cached areas. Note +that you must call cairo_surface_flush() before doing such drawing.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+

Since 1.0

+
+
+
+

cairo_surface_mark_dirty_rectangle ()

+
void
+cairo_surface_mark_dirty_rectangle (cairo_surface_t *surface,
+                                    int x,
+                                    int y,
+                                    int width,
+                                    int height);
+

Like cairo_surface_mark_dirty(), but drawing has been done only to +the specified rectangle, so that cairo can retain cached contents +for other parts of the surface.

+

Any cached clip set on the surface will be reset by this function, +to make sure that future cairo calls have the clip set that they +expect.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

x

X coordinate of dirty rectangle

 

y

Y coordinate of dirty rectangle

 

width

width of dirty rectangle

 

height

height of dirty rectangle

cairo_surface_set_device_offset ()

+
void
+cairo_surface_set_device_offset (cairo_surface_t *surface,
+                                 double x_offset,
+                                 double y_offset);
+

Sets an offset that is added to the device coordinates determined +by the CTM when drawing to surface +. One use case for this function +is when we want to create a cairo_surface_t that redirects drawing +for a portion of an onscreen surface to an offscreen surface in a +way that is completely invisible to the user of the cairo +API. Setting a transformation via cairo_translate() isn't +sufficient to do this, since functions like +cairo_device_to_user() will expose the hidden offset.

+

Note that the offset affects drawing to the surface as well as +using the surface in a source pattern.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

x_offset

the offset in the X direction, in device units

 

y_offset

the offset in the Y direction, in device units

 
+
+

Since 1.0

+
+
+
+

cairo_surface_get_device_offset ()

+
void
+cairo_surface_get_device_offset (cairo_surface_t *surface,
+                                 double *x_offset,
+                                 double *y_offset);
+

This function returns the previous device offset set by +cairo_surface_set_device_offset().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

x_offset

the offset in the X direction, in device units

 

y_offset

the offset in the Y direction, in device units

 
+
+

Since 1.2

+
+
+
+

cairo_surface_get_device_scale ()

+
void
+cairo_surface_get_device_scale (cairo_surface_t *surface,
+                                double *x_scale,
+                                double *y_scale);
+

This function returns the previous device offset set by +cairo_surface_set_device_scale().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

x_scale

the scale in the X direction, in device units

 

y_scale

the scale in the Y direction, in device units

 
+
+

Since 1.14

+
+
+
+

cairo_surface_set_device_scale ()

+
void
+cairo_surface_set_device_scale (cairo_surface_t *surface,
+                                double x_scale,
+                                double y_scale);
+

Sets a scale that is multiplied to the device coordinates determined +by the CTM when drawing to surface +. One common use for this is to +render to very high resolution display devices at a scale factor, so +that code that assumes 1 pixel will be a certain size will still work. +Setting a transformation via cairo_translate() isn't +sufficient to do this, since functions like +cairo_device_to_user() will expose the hidden scale.

+

Note that the scale affects drawing to the surface as well as +using the surface in a source pattern.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

x_scale

a scale factor in the X direction

 

y_scale

a scale factor in the Y direction

cairo_surface_set_fallback_resolution ()

+
void
+cairo_surface_set_fallback_resolution (cairo_surface_t *surface,
+                                       double x_pixels_per_inch,
+                                       double y_pixels_per_inch);
+

Set the horizontal and vertical resolution for image fallbacks.

+

When certain operations aren't supported natively by a backend, +cairo will fallback by rendering operations to an image and then +overlaying that image onto the output. For backends that are +natively vector-oriented, this function can be used to set the +resolution used for these image fallbacks, (larger values will +result in more detailed images, but also larger file sizes).

+

Some examples of natively vector-oriented backends are the ps, pdf, +and svg backends.

+

For backends that are natively raster-oriented, image fallbacks are +still possible, but they are always performed at the native +device resolution. So this function has no effect on those +backends.

+

Note: The fallback resolution only takes effect at the time of +completing a page (with cairo_show_page() or cairo_copy_page()) so +there is currently no way to have more than one fallback resolution +in effect on a single page.

+

The default fallback resoultion is 300 pixels per inch in both +dimensions.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

x_pixels_per_inch

horizontal setting for pixels per inch

+                             const cairo_user_data_key_t *key);
+

Return user data previously attached to surface + using the specified +key. If no user data has been attached with the given key this +function returns NULL.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

surface

a cairo_surface_t

 

key

the address of the cairo_user_data_key_t the user data was +attached to

 
+
+
+

Returns

+

the user data previously attached or NULL.

cairo_surface_copy_page ()

+
void
+cairo_surface_copy_page (cairo_surface_t *surface);
+

Emits the current page for backends that support multiple pages, +but doesn't clear it, so that the contents of the current page will +be retained for the next page. Use cairo_surface_show_page() if you +want to get an empty page after the emission.

+

There is a convenience function for this that takes a cairo_t, +namely cairo_copy_page().

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+

Since 1.6

+
+

cairo_surface_show_page ()

+
void
+cairo_surface_show_page (cairo_surface_t *surface);
+

Emits and clears the current page for backends that support multiple +pages. Use cairo_surface_copy_page() if you don't want to clear the page.

+

There is a convenience function for this that takes a cairo_t, +namely cairo_show_page().

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_Surface_t

+

Since 1.6

+
+
+
+

cairo_surface_has_show_text_glyphs ()

+
cairo_bool_t
+cairo_surface_has_show_text_glyphs (cairo_surface_t *surface);
+

Returns whether the surface supports +sophisticated cairo_show_text_glyphs() operations. That is, +whether it actually uses the provided text and cluster data +to a cairo_show_text_glyphs() call.

+

Note: Even if this function returns FALSE, a +cairo_show_text_glyphs() operation targeted at surface + will +still succeed. It just will +act like a cairo_show_glyphs() operation. Users can use this +function to avoid computing UTF-8 text and cluster mapping if the +target surface does not use it.

+
+

Parameters

+
+++++ + + + + + +

surface

a cairo_surface_t

 
+
+
+

Returns

+

TRUE if surface +supports +cairo_show_text_glyphs(), FALSE otherwise

cairo_surface_set_mime_data ()

+
cairo_status_t
+cairo_surface_set_mime_data (cairo_surface_t *surface,
+                             const char *mime_type,
+                             const unsigned char *data,
+                             unsigned long  length,
+                             cairo_destroy_func_t destroy,
+                             void *closure);
+

Attach an image in the format mime_type + to surface +. To remove +the data from a surface, call this function with same mime type +and NULL for data +.

+

The attached image (or filename) data can later be used by backends +which support it (currently: PDF, PS, SVG and Win32 Printing +surfaces) to emit this data instead of making a snapshot of the +surface +. This approach tends to be faster and requires less +memory and disk space.

+

The recognized MIME types are the following: CAIRO_MIME_TYPE_JPEG, +CAIRO_MIME_TYPE_PNG, CAIRO_MIME_TYPE_JP2, CAIRO_MIME_TYPE_URI, +CAIRO_MIME_TYPE_UNIQUE_ID, CAIRO_MIME_TYPE_JBIG2, +CAIRO_MIME_TYPE_JBIG2_GLOBAL, CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID.

+

See corresponding backend surface docs for details about which MIME +types it can handle. Caution: the associated MIME data will be +discarded if you draw on the surface afterwards. Use this function +with care.

+

Even if a backend supports a MIME type, that does not mean cairo +will always be able to use the attached MIME data. For example, if +the backend does not natively support the compositing operation used +to apply the MIME data to the backend. In that case, the MIME data +will be ignored. Therefore, to apply an image in all cases, it is best +to create an image surface which contains the decoded image data and +then attach the MIME data to that. This ensures the image will always +be used while still allowing the MIME data to be used whenever +possible.

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

surface

a cairo_surface_t

 

mime_type

the MIME type of the image data

 

data

Returns

+

CAIRO_STATUS_SUCCESS or CAIRO_STATUS_NO_MEMORY if a +slot could not be allocated for the user data.

cairo_surface_t *
+cairo_surface_map_to_image (cairo_surface_t *surface,
+                            const cairo_rectangle_int_t *extents);
+

Returns an image surface that is the most efficient mechanism for +modifying the backing store of the target surface. The region retrieved +may be limited to the extents + or NULL for the whole surface

+

Note, the use of the original surface as a target or source whilst +it is mapped is undefined. The result of mapping the surface +multiple times is undefined. Calling cairo_surface_destroy() or +cairo_surface_finish() on the resulting image surface results in +undefined behavior. Changing the device transform of the image +surface or of surface + before the image surface is unmapped results +in undefined behavior.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

surface

an existing surface used to extract the image from

 

extents

limit the extraction to an rectangular region

 
+
+
+

Returns

+

a pointer to the newly allocated image surface. The caller +must use cairo_surface_unmap_image() to destroy this image surface.

+

This function always returns a valid pointer, but it will return a +pointer to a "nil" surface if other +is already in an error state +or any other error occurs. If the returned pointer does not have an +error status, it is guaranteed to be an image surface whose format +is not CAIRO_FORMAT_INVALID.

+

void
+cairo_surface_unmap_image (cairo_surface_t *surface,
+                           cairo_surface_t *image);
+

Unmaps the image surface as returned from cairo_surface_map_to_image().

+

The content of the image will be uploaded to the target surface. +Afterwards, the image is destroyed.

+

Using an image surface which wasn't returned by cairo_surface_map_to_image() +results in undefined behavior.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

surface

the surface passed to cairo_surface_map_to_image().

 

image

the currently mapped image

cairo_surface_t

+
typedef struct _cairo_surface cairo_surface_t;
+
+

A cairo_surface_t represents an image, either as the destination +of a drawing operation or as source when drawing onto another +surface. To draw to a cairo_surface_t, create a cairo context +with the surface as the target, using cairo_create().

+

There are different subtypes of cairo_surface_t for +different drawing backends; for example, cairo_image_surface_create() +creates a bitmap image in memory. +The type of a surface can be queried with cairo_surface_get_type().

+

The initial contents of a surface after creation depend upon the manner +of its creation. If cairo creates the surface and backing storage for +the user, it will be initially cleared; for example, +cairo_image_surface_create() and cairo_surface_create_similar(). +Alternatively, if the user passes in a reference to some backing storage +and asks cairo to wrap that in a cairo_surface_t, then the contents are +not modified; for example, cairo_image_surface_create_for_data() and +cairo_xlib_surface_create().

+

Memory management of cairo_surface_t is done with +cairo_surface_reference() and cairo_surface_destroy().

+

Since 1.0

+
+
+
+

enum cairo_content_t

+

cairo_content_t is used to describe the content that a surface will +contain, whether color information, alpha information (translucence +vs. opacity), or both.

+

Note: The large values here are designed to keep cairo_content_t +values distinct from cairo_format_t values so that the +implementation can detect the error if users confuse the two types.

enum cairo_surface_type_t

+

cairo_surface_type_t is used to describe the type of a given +surface. The surface types are also known as "backends" or "surface +backends" within cairo.

+

The type of a surface is determined by the function used to create +it, which will generally be of the form +cairo_type_surface_create(), +(though see cairo_surface_create_similar() as well).

+

The surface type can be queried with cairo_surface_get_type()

+

The various cairo_surface_t functions can be used with surfaces of +any type, but some backends also provide type-specific functions +that must only be called with a surface of the appropriate +type. These functions have names that begin with +cairo_type_surface such as cairo_image_surface_get_width().

+

The behavior of calling a type-specific function with a surface of +the wrong type is undefined.

+

New entries may be added in future versions.

Object Hierarchy

+
+
+
+
+

Description

+

cairo_t is the main object used when drawing with cairo. To +draw with cairo, you create a cairo_t, set the target surface, +and drawing options for the cairo_t, create shapes with +functions like cairo_move_to() and cairo_line_to(), and then +draw shapes with cairo_stroke() or cairo_fill().

+

cairo_t's can be pushed to a stack via cairo_save(). +They may then safely be changed, without losing the current state. +Use cairo_restore() to restore to the saved state.

+
+
+

Functions

+
+

cairo_create ()

+
cairo_t *
+cairo_create (cairo_surface_t *target);
+

Creates a new cairo_t with all graphics state parameters set to +default values and with target + as a target surface. The target +surface should be constructed with a backend-specific function such +as cairo_image_surface_create() (or any other +cairo_backend_surface_create() +variant).

+

This function references target +, so you can immediately +call cairo_surface_destroy() on it if you don't need to +maintain a separate reference to it.

+
+

Parameters

+
+++++ + + + + + +

target

target surface for the context

 
+
+
+

Returns

+

a newly allocated cairo_t with a reference +count of 1. The initial reference count should be released +with cairo_destroy() when you are done using the cairo_t. +This function never returns NULL. If memory cannot be +allocated, a special cairo_t object will be returned on +which cairo_status() returns CAIRO_STATUS_NO_MEMORY. If +you attempt to target a surface which does not support +writing (such as cairo_mime_surface_t) then a +CAIRO_STATUS_WRITE_ERROR will be raised. You can use this +object normally, but no drawing will be done.

+

+
+

Since 1.0

+
+
+
+

cairo_reference ()

+
cairo_t *
+cairo_reference (cairo_t *cr);
+

Increases the reference count on cr + by one. This prevents +cr + from being destroyed until a matching call to cairo_destroy() +is made.

+

The number of references to a cairo_t can be get using +cairo_get_reference_count().

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo_t

 
+
+
+

Returns

+

the referenced cairo_t.

+

+
+

Since 1.0

+
+
+
+

cairo_destroy ()

+
void
+cairo_destroy (cairo_t *cr);
+

Decreases the reference count on cr + by one. If the result +is zero, then cr + and all associated resources are freed. +See cairo_reference().

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo_t

 
+
+

Since 1.0

+
+
+
+

cairo_status ()

+
cairo_status_t
+cairo_status (cairo_t *cr);
+

Checks whether an error has previously occurred for this context.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

the current status of this context, see cairo_status_t

+

+
+

Since 1.0

+
+
+
+

cairo_save ()

+
void
+cairo_save (cairo_t *cr);
+

Makes a copy of the current state of cr + and saves it +on an internal stack of saved states for cr +. When +cairo_restore() is called, cr + will be restored to +the saved state. Multiple calls to cairo_save() and +cairo_restore() can be nested; each call to cairo_restore() +restores the state from the matching paired cairo_save().

+

It isn't necessary to clear all saved states before +a cairo_t is freed. If the reference count of a cairo_t +drops to zero in response to a call to cairo_destroy(), +any saved states will be freed along with the cairo_t.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo_t

 
+
+

Since 1.0

+
+
+
+

cairo_restore ()

+
void
+cairo_restore (cairo_t *cr);
+

Restores cr + to the state saved by a preceding call to +cairo_save() and removes that state from the stack of +saved states.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo_t

 
+
+

Since 1.0

+
+
+
+

cairo_get_target ()

+
cairo_surface_t *
+cairo_get_target (cairo_t *cr);
+

Gets the target surface for the cairo context as passed to +cairo_create().

+

This function will always return a valid pointer, but the result +can be a "nil" surface if cr + is already in an error state, +(ie. cairo_status() != CAIRO_STATUS_SUCCESS). +A nil surface is indicated by cairo_surface_status() +!= CAIRO_STATUS_SUCCESS.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

the target surface. This object is owned by cairo. To +keep a reference to it, you must call cairo_surface_reference().

+

+
+

Since 1.0

+
+
+
+

cairo_push_group ()

+
void
+cairo_push_group (cairo_t *cr);
+

Temporarily redirects drawing to an intermediate surface known as a +group. The redirection lasts until the group is completed by a call +to cairo_pop_group() or cairo_pop_group_to_source(). These calls +provide the result of any drawing to the group as a pattern, +(either as an explicit object, or set as the source pattern).

+

This group functionality can be convenient for performing +intermediate compositing. One common use of a group is to render +objects as opaque within the group, (so that they occlude each +other), and then blend the result with translucence onto the +destination.

+

Groups can be nested arbitrarily deep by making balanced calls to +cairo_push_group()/cairo_pop_group(). Each call pushes/pops the new +target group onto/from a stack.

+

The cairo_push_group() function calls cairo_save() so that any +changes to the graphics state will not be visible outside the +group, (the pop_group functions call cairo_restore()).

+

By default the intermediate group will have a content type of +CAIRO_CONTENT_COLOR_ALPHA. Other content types can be chosen for +the group by using cairo_push_group_with_content() instead.

+

As an example, here is how one might fill and stroke a path with +translucence, but without any portion of the fill being visible +under the stroke:

+
+cairo_push_group (cr);
+cairo_set_source (cr, fill_pattern);
+cairo_fill_preserve (cr);
+cairo_set_source (cr, stroke_pattern);
+cairo_stroke (cr);
+cairo_pop_group_to_source (cr);
+cairo_paint_with_alpha (cr, alpha);
+
+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+

Since 1.2

+
+
+
+

cairo_push_group_with_content ()

+
void
+cairo_push_group_with_content (cairo_t *cr,
+                               cairo_content_t content);
+

Temporarily redirects drawing to an intermediate surface known as a +group. The redirection lasts until the group is completed by a call +to cairo_pop_group() or cairo_pop_group_to_source(). These calls +provide the result of any drawing to the group as a pattern, +(either as an explicit object, or set as the source pattern).

+

The group will have a content type of content +. The ability to +control this content type is the only distinction between this +function and cairo_push_group() which you should see for a more +detailed description of group rendering.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo context

 

content

a cairo_content_t indicating the type of group that +will be created

 
+
+

Since 1.2

+
+
+
+

cairo_pop_group ()

+
cairo_pattern_t *
+cairo_pop_group (cairo_t *cr);
+

Terminates the redirection begun by a call to cairo_push_group() or +cairo_push_group_with_content() and returns a new pattern +containing the results of all drawing operations performed to the +group.

+

The cairo_pop_group() function calls cairo_restore(), (balancing a +call to cairo_save() by the push_group function), so that any +changes to the graphics state will not be visible outside the +group.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

a newly created (surface) pattern containing the +results of all drawing operations performed to the group. The +caller owns the returned object and should call +cairo_pattern_destroy() when finished with it.

+

+
+

Since 1.2

+
+
+
+

cairo_pop_group_to_source ()

+
void
+cairo_pop_group_to_source (cairo_t *cr);
+

Terminates the redirection begun by a call to cairo_push_group() or +cairo_push_group_with_content() and installs the resulting pattern +as the source pattern in the given cairo context.

+

The behavior of this function is equivalent to the sequence of +operations:

+
+cairo_pattern_t *group = cairo_pop_group (cr);
+cairo_set_source (cr, group);
+cairo_pattern_destroy (group);
+
+

but is more convenient as their is no need for a variable to store +the short-lived pointer to the pattern.

+

The cairo_pop_group() function calls cairo_restore(), (balancing a +call to cairo_save() by the push_group function), so that any +changes to the graphics state will not be visible outside the +group.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+

Since 1.2

+
+
+
+

cairo_get_group_target ()

+
cairo_surface_t *
+cairo_get_group_target (cairo_t *cr);
+

Gets the current destination surface for the context. This is either +the original target surface as passed to cairo_create() or the target +surface for the current group as started by the most recent call to +cairo_push_group() or cairo_push_group_with_content().

+

This function will always return a valid pointer, but the result +can be a "nil" surface if cr + is already in an error state, +(ie. cairo_status() != CAIRO_STATUS_SUCCESS). +A nil surface is indicated by cairo_surface_status() +!= CAIRO_STATUS_SUCCESS.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo context

 
+
+
+

Returns

+

the target surface. This object is owned by cairo. To +keep a reference to it, you must call cairo_surface_reference().

+

+                      double green,
+                      double blue);
+

Sets the source pattern within cr + to an opaque color. This opaque +color will then be used for any subsequent drawing operation until +a new source pattern is set.

+

The color components are floating point numbers in the range 0 to

+

  1. If the values passed in are outside that range, they will be +clamped.

+

The default source pattern is opaque black, (that is, it is +equivalent to cairo_set_source_rgb(cr, 0.0, 0.0, 0.0)).

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

+                       double blue,
+                       double alpha);
+

Sets the source pattern within cr + to a translucent color. This +color will then be used for any subsequent drawing operation until +a new source pattern is set.

+

The color and alpha components are floating point numbers in the +range 0 to 1. If the values passed in are outside that range, they +will be clamped.

+

The default source pattern is opaque black, (that is, it is +equivalent to cairo_set_source_rgba(cr, 0.0, 0.0, 0.0, 1.0)).

+
+

Parameters

cairo_set_source ()

+
void
+cairo_set_source (cairo_t *cr,
+                  cairo_pattern_t *source);
+

Sets the source pattern within cr + to source +. This pattern +will then be used for any subsequent drawing operation until a new +source pattern is set.

+

Note: The pattern's transformation matrix will be locked to the +user space in effect at the time of cairo_set_source(). This means +that further modifications of the current transformation matrix +will not affect the source pattern. See cairo_pattern_set_matrix().

+

The default source pattern is a solid pattern that is opaque black, +(that is, it is equivalent to cairo_set_source_rgb(cr, 0.0, 0.0, +0.0)).

+
+

Parameters

+                          double x,
+                          double y);
+

This is a convenience function for creating a pattern from surface + +and setting it as the source in cr + with cairo_set_source().

+

The x + and y + parameters give the user-space coordinate at which +the surface origin should appear. (The surface origin is its +upper-left corner before any transformation has been applied.) The +x + and y + parameters are negated and then set as translation values +in the pattern matrix.

+

Other than the initial translation pattern matrix, as described +above, all other pattern attributes, (such as its extend mode), are +set to the default values as in cairo_pattern_create_for_surface(). +The resulting pattern can be queried with cairo_get_source() so +that these attributes can be modified if desired, (eg. to create a +repeating pattern with cairo_pattern_set_extend()).

+
+

Parameters

+                int num_dashes,
+                double offset);
+

Sets the dash pattern to be used by cairo_stroke(). A dash pattern +is specified by dashes +, an array of positive values. Each value +provides the length of alternate "on" and "off" portions of the +stroke. The offset + specifies an offset into the pattern at which +the stroke begins.

+

Each "on" segment will have caps applied as if the segment were a +separate sub-path. In particular, it is valid to use an "on" length +of 0.0 with CAIRO_LINE_CAP_ROUND or CAIRO_LINE_CAP_SQUARE in order +to distributed dots or squares along a path.

+

Note: The length values are in user-space units as evaluated at the +time of stroking. This is not necessarily the same as the user +space at the time of cairo_set_dash().

+

If num_dashes + is 0 dashing is disabled.

+

If num_dashes + is 1 a symmetric pattern is assumed with alternating +on and off portions of the size specified by the single value in +dashes +.

+

If any value in dashes + is negative, or if all values are 0, then +cr + will be put into an error state with a status of +CAIRO_STATUS_INVALID_DASH.

+                     cairo_fill_rule_t fill_rule);
+

Set the current fill rule within the cairo context. The fill rule +is used to determine which regions are inside or outside a complex +(potentially self-intersecting) path. The current fill rule affects +both cairo_fill() and cairo_clip(). See cairo_fill_rule_t for details +on the semantics of each available fill rule.

+

Sets the current line cap style within the cairo context. See +cairo_line_cap_t for details about how the available line cap +styles are drawn.

+

As with the other stroke parameters, the current line cap style is +examined by cairo_stroke(), cairo_stroke_extents(), and +cairo_stroke_to_path(), but does not have any effect during path +construction.

+

The default line cap style is CAIRO_LINE_CAP_BUTT.

+
void
+cairo_set_line_join (cairo_t *cr,

+

Sets the current line join style within the cairo context. See +cairo_line_join_t for details about how the available line join +styles are drawn.

+

As with the other stroke parameters, the current line join style is +examined by cairo_stroke(), cairo_stroke_extents(), and +cairo_stroke_to_path(), but does not have any effect during path +construction.

+

The default line join style is CAIRO_LINE_JOIN_MITER.

cairo_set_line_width ()

+
void
+cairo_set_line_width (cairo_t *cr,
+                      double width);
+

Sets the current line width within the cairo context. The line +width value specifies the diameter of a pen that is circular in +user space, (though device-space pen may be an ellipse in general +due to scaling/shear/rotation of the CTM).

+

Note: When the description above refers to user space and CTM it +refers to the user space and CTM in effect at the time of the +stroking operation, not the user space and CTM in effect at the +time of the call to cairo_set_line_width(). The simplest usage +makes both of these spaces identical. That is, if there is no +change to the CTM between a call to cairo_set_line_width() and the +stroking operation, then one can just pass user-space values to +cairo_set_line_width() and ignore this note.

+

As with the other stroke parameters, the current line width is +examined by cairo_stroke(), cairo_stroke_extents(), and +cairo_stroke_to_path(), but does not have any effect during path +construction.

+

The default line width value is 2.0.

+
+

Parameters

cairo_set_miter_limit ()

+
void
+cairo_set_miter_limit (cairo_t *cr,
+                       double limit);
+

Sets the current miter limit within the cairo context.

+

If the current line join style is set to CAIRO_LINE_JOIN_MITER +(see cairo_set_line_join()), the miter limit is used to determine +whether the lines should be joined with a bevel instead of a miter. +Cairo divides the length of the miter by the line width. +If the result is greater than the miter limit, the style is +converted to a bevel.

+

As with the other stroke parameters, the current line miter limit is +examined by cairo_stroke(), cairo_stroke_extents(), and +cairo_stroke_to_path(), but does not have any effect during path +construction.

+

The default miter limit value is 10.0, which will convert joins +with interior angles less than 11 degrees to bevels instead of +miters. For reference, a miter limit of 2.0 makes the miter cutoff +at 60 degrees, and a miter limit of 1.414 makes the cutoff at 90 +degrees.

+

A miter limit for a desired angle can be computed as: miter limit = +1/sin(angle/2)

+
+

+

Sets the tolerance used when converting paths into trapezoids. +Curved segments of the path will be subdivided until the maximum +deviation between the original path and the polygonal approximation +is less than tolerance +. The default value is 0.1. A larger +value will give better performance, a smaller value, better +appearance. (Reducing the value from the default value of 0.1 +is unlikely to improve appearance significantly.) The accuracy of paths +within Cairo is limited by the precision of its internal arithmetic, and +the prescribed tolerance + is restricted to the smallest +representable internal value.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo_t

 

tolerance

the tolerance, in device units (typically pixels)

double
+cairo_get_tolerance (cairo_t *cr);
+

Gets the current tolerance value, as set by cairo_set_tolerance().

cairo_clip ()

+
void
+cairo_clip (cairo_t *cr);
+

Establishes a new clip region by intersecting the current clip +region with the current path as it would be filled by cairo_fill() +and according to the current fill rule (see cairo_set_fill_rule()).

+

After cairo_clip(), the current path will be cleared from the cairo +context.

+

The current clip region affects all drawing operations by +effectively masking out any changes to the surface that are outside +the current clip region.

+

Calling cairo_clip() can only make the clip region smaller, never +larger. But the current clip is part of the graphics state, so a +temporary restriction of the clip region can be achieved by +calling cairo_clip() within a cairo_save()/cairo_restore() +pair. The only other means of increasing the size of the clip +region is cairo_reset_clip().

+
+

Parameters

+

Establishes a new clip region by intersecting the current clip +region with the current path as it would be filled by cairo_fill() +and according to the current fill rule (see cairo_set_fill_rule()).

+

Unlike cairo_clip(), cairo_clip_preserve() preserves the path within +the cairo context.

cairo_bool_t
+cairo_in_clip (cairo_t *cr,
+               double x,

+

Tests whether the given point is inside the area that would be +visible through the current clip, i.e. the area that would be filled by +a cairo_paint() operation.

+

See cairo_clip(), and cairo_clip_preserve().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + +

cr

a cairo context

 

x

X coordinate of the point to test

+
+
+
+

cairo_reset_clip ()

+
void
+cairo_reset_clip (cairo_t *cr);
+

Reset the current clip region to its original, unrestricted +state. That is, set the clip region to an infinitely large shape +containing the target surface. Equivalently, if infinity is too +hard to grasp, one can imagine the clip region being reset to the +exact bounds of the target surface.

+

Note that code meant to be reusable should not call +cairo_reset_clip() as it will cause results unexpected by +higher-level code which calls cairo_clip(). Consider using +cairo_save() and cairo_restore() around cairo_clip() as a more +robust means of temporarily restricting the clip region.

+

Gets the current clip region as a list of rectangles in user coordinates. +Never returns NULL.

+

The status in the list may be CAIRO_STATUS_CLIP_NOT_REPRESENTABLE to +indicate that the clip region cannot be represented as a list of +user-space rectangles. The status may have other values to indicate +other errors.

+
+

Parameters

+
+++++ + + + + + +

cr

Returns

+

the current clip region as a list of rectangles in user coordinates, +which should be destroyed using cairo_rectangle_list_destroy().

cairo_fill ()

+
void
+cairo_fill (cairo_t *cr);
+

A drawing operator that fills the current path according to the +current fill rule, (each sub-path is implicitly closed before being +filled). After cairo_fill(), the current path will be cleared from +the cairo context. See cairo_set_fill_rule() and +cairo_fill_preserve().

cairo_fill_preserve ()

+
void
+cairo_fill_preserve (cairo_t *cr);
+

A drawing operator that fills the current path according to the +current fill rule, (each sub-path is implicitly closed before being +filled). Unlike cairo_fill(), cairo_fill_preserve() preserves the +path within the cairo context.

+                    double *x2,
+                    double *y2);
+

Computes a bounding box in user coordinates covering the area that +would be affected, (the "inked" area), by a cairo_fill() operation +given the current path and fill parameters. If the current path is +empty, returns an empty rectangle ((0,0), (0,0)). Surface +dimensions and clipping are not taken into account.

+

Contrast with cairo_path_extents(), which is similar, but returns +non-zero extents for some paths with no inked area, (such as a +simple line segment).

+

Note that cairo_fill_extents() must necessarily do more work to +compute the precise inked areas in light of the fill rule, so +cairo_path_extents() may be more desirable for sake of performance +if the non-inked path extents are desired.

+

void
+cairo_paint_with_alpha (cairo_t *cr,

+
+

cairo_stroke ()

+
void
+cairo_stroke (cairo_t *cr);
+

A drawing operator that strokes the current path according to the +current line width, line join, line cap, and dash settings. After +cairo_stroke(), the current path will be cleared from the cairo +context. See cairo_set_line_width(), cairo_set_line_join(), +cairo_set_line_cap(), cairo_set_dash(), and +cairo_stroke_preserve().

+

Note: Degenerate segments and sub-paths are treated specially and +provide a useful result. These can result in two different +situations:

+
    +

  1. Zero-length "on" segments set in cairo_set_dash(). If the cap +style is CAIRO_LINE_CAP_ROUND or CAIRO_LINE_CAP_SQUARE then these +segments will be drawn as circular dots or squares respectively. In +the case of CAIRO_LINE_CAP_SQUARE, the orientation of the squares +is determined by the direction of the underlying path.

    2. +

  2. A sub-path created by cairo_move_to() followed by either a +cairo_close_path() or one or more calls to cairo_line_to() to the +same coordinate as the cairo_move_to(). If the cap style is +CAIRO_LINE_CAP_ROUND then these sub-paths will be drawn as circular +dots. Note that in the case of CAIRO_LINE_CAP_SQUARE a degenerate +sub-path will not be drawn at all, (since the correct orientation +is indeterminate).

    3. +
+

In no case will a cap style of CAIRO_LINE_CAP_BUTT cause anything +to be drawn in the case of either degenerate segments or sub-paths.

+
+

cairo_stroke_preserve ()

+
void
+cairo_stroke_preserve (cairo_t *cr);
+

A drawing operator that strokes the current path according to the +current line width, line join, line cap, and dash settings. Unlike +cairo_stroke(), cairo_stroke_preserve() preserves the path within the +cairo context.

+

See cairo_set_line_width(), cairo_set_line_join(), +cairo_set_line_cap(), cairo_set_dash(), and +cairo_stroke_preserve().

+                      double *x2,
+                      double *y2);
+

Computes a bounding box in user coordinates covering the area that +would be affected, (the "inked" area), by a cairo_stroke() +operation given the current path and stroke parameters. +If the current path is empty, returns an empty rectangle ((0,0), (0,0)). +Surface dimensions and clipping are not taken into account.

+

Note that if the line width is set to exactly zero, then +cairo_stroke_extents() will return an empty rectangle. Contrast with +cairo_path_extents() which can be used to compute the non-empty +bounds as the line width approaches zero.

+

Note that cairo_stroke_extents() must necessarily do more work to +compute the precise inked areas in light of the stroke parameters, +so cairo_path_extents() may be more desirable for sake of +performance if non-inked path extents are desired.

Types and Values

+
+

cairo_t

+
typedef struct _cairo cairo_t;
+
+

A cairo_t contains the current state of the rendering device, +including coordinates of yet to be drawn shapes.

+

Cairo contexts, as cairo_t objects are named, are central to +cairo and all drawing with cairo is always done to a cairo_t +object.

+

Memory management of cairo_t is done with +cairo_reference() and cairo_destroy().

+

Since 1.0

+
+
+
+

enum cairo_antialias_t

+

Specifies the type of antialiasing to do when rendering text or shapes.

+

As it is not necessarily clear from the above what advantages a particular +antialias method provides, since 1.12, there is also a set of hints: +CAIRO_ANTIALIAS_FAST +: Allow the backend to degrade raster quality for speed +CAIRO_ANTIALIAS_GOOD +: A balance between speed and quality +CAIRO_ANTIALIAS_BEST +: A high-fidelity, but potentially slow, raster mode

+

These make no guarantee on how the backend will perform its rasterisation +(if it even rasterises!), nor that they have any differing effect other +than to enable some form of antialiasing. In the case of glyph rendering, +CAIRO_ANTIALIAS_FAST + and CAIRO_ANTIALIAS_GOOD + will be mapped to +CAIRO_ANTIALIAS_GRAY +, with CAIRO_ANTALIAS_BEST + being equivalent to +CAIRO_ANTIALIAS_SUBPIXEL +.

+

The interpretation of CAIRO_ANTIALIAS_DEFAULT + is left entirely up to +the backend, typically this will be similar to CAIRO_ANTIALIAS_GOOD +.

+

Members

CAIRO_ANTIALIAS_SUBPIXEL

 +

Perform antialiasing by taking + advantage of the order of subpixel elements on devices + such as LCD panels, since 1.0

CAIRO_ANTIALIAS_FAST

 +

Hint that the backend should perform some +antialiasing but prefer speed over quality, since 1.12

+		 

CAIRO_ANTIALIAS_GOOD

 +

The backend should balance quality against +performance, since 1.12

enum cairo_fill_rule_t

+

cairo_fill_rule_t is used to select how paths are filled. For both +fill rules, whether or not a point is included in the fill is +determined by taking a ray from that point to infinity and looking +at intersections with the path. The ray can be in any direction, +as long as it doesn't pass through the end point of a segment +or have a tricky intersection such as intersecting tangent to the path. +(Note that filling is not actually implemented in this way. This +is just a description of the rule that is applied.)

The default fill rule is CAIRO_FILL_RULE_WINDING.

New entries may be added in future versions.

enum cairo_operator_t

+

cairo_operator_t is used to set the compositing operator for all cairo +drawing operations.

+

The default operator is CAIRO_OPERATOR_OVER.

+

The operators marked as unbounded modify their +destination even outside of the mask layer (that is, their effect is not +bound by the mask layer). However, their effect can still be limited by +way of clipping.

+

To keep things simple, the operator descriptions here +document the behavior for when both source and destination are either fully +transparent or fully opaque. The actual implementation works for +translucent layers too. +For a more detailed explanation of the effects of each operator, including +the mathematical definitions, see

+http://cairographics.org/operators/. +

Description

+

The functions with text in their name form cairo's +toy text API. The toy API takes UTF-8 encoded +text and is limited in its functionality to rendering simple +left-to-right text with no advanced features. That means for example +that most complex scripts like Hebrew, Arabic, and Indic scripts are +out of question. No kerning or correct positioning of diacritical marks +either. The font selection is pretty limited too and doesn't handle the +case that the selected font does not cover the characters in the text. +This set of functions are really that, a toy text API, for testing and +demonstration purposes. Any serious application should avoid them.

+

The functions with glyphs in their name form cairo's +low-level text API. The low-level API relies on +the user to convert text to a set of glyph indexes and positions. This +is a very hard problem and is best handled by external libraries, like +the pangocairo that is part of the Pango text layout and rendering library. +Pango is available from http://www.pango.org/.

+
+
+

Functions

+
+

cairo_select_font_face ()

+
void
+cairo_select_font_face (cairo_t *cr,
+                        const char *family,
+                        cairo_font_slant_t slant,
+                        cairo_font_weight_t weight);
+

Note: The cairo_select_font_face() function call is part of what +the cairo designers call the "toy" text API. It is convenient for +short demos and simple programs, but it is not expected to be +adequate for serious text-using applications.

+

Selects a family and style of font from a simplified description as +a family name, slant and weight. Cairo provides no operation to +list available family names on the system (this is a "toy", +remember), but the standard CSS2 generic family names, ("serif", +"sans-serif", "cursive", "fantasy", "monospace"), are likely to +work as expected.

+

If family + starts with the string "cairo +:", or if no native font +backends are compiled in, cairo will use an internal font family. +The internal font family recognizes many modifiers in the family + +string, most notably, it recognizes the string "monospace". That is, +the family name "cairo +:monospace" will use the monospace version of +the internal font family.

+

For "real" font selection, see the font-backend-specific +font_face_create functions for the font backend you are using. (For +example, if you are using the freetype-based cairo-ft font backend, +see cairo_ft_font_face_create_for_ft_face() or +cairo_ft_font_face_create_for_pattern().) The resulting font face +could then be used with cairo_scaled_font_create() and +cairo_set_scaled_font().

+

Similarly, when using the "real" font support, you can call +directly into the underlying font system, (such as fontconfig or +freetype), for operations such as listing available fonts, etc.

+

It is expected that most applications will need to use a more +comprehensive font handling and text layout library, (for example, +pango), in conjunction with cairo.

+

If text is drawn without a call to cairo_select_font_face(), (nor +cairo_set_font_face() nor cairo_set_scaled_font()), the default +family is platform-specific, but is essentially "sans-serif". +Default slant is CAIRO_FONT_SLANT_NORMAL, and default weight is +CAIRO_FONT_WEIGHT_NORMAL.

+

This function is equivalent to a call to cairo_toy_font_face_create() +followed by cairo_set_font_face().

+
+

Parameters

+
+++++ + + + + + + + + + + + + + + + + + + + + + + +

cr

a cairo_t

 

family

a font family name, encoded in UTF-8

 

slant

the slant for the font

 

weight

the weight for the font

 
+
+

Since 1.0

+
+
+
+

cairo_set_font_size ()

+
void
+cairo_set_font_size (cairo_t *cr,
+                     double size);
+

Sets the current font matrix to a scale by a factor of size +, replacing +any font matrix previously set with cairo_set_font_size() or +cairo_set_font_matrix(). This results in a font size of size + user space +units. (More precisely, this matrix will result in the font's +em-square being a size + by size + square in user space.)

+

If text is drawn without a call to cairo_set_font_size(), (nor +cairo_set_font_matrix() nor cairo_set_scaled_font()), the default +font size is 10.0.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo_t

 

size

the new font size, in user space units

 
+
+

Since 1.0

+
void
+cairo_set_font_matrix (cairo_t *cr,
+                       const cairo_matrix_t *matrix);
+

Sets the current font matrix to matrix +. The font matrix gives a +transformation from the design space of the font (in this space, +the em-square is 1 unit by 1 unit) to user space. Normally, a +simple scale is used (see cairo_set_font_size()), but a more +complex font matrix can be used to shear the font +or stretch it unequally along the two axes

+
+

Parameters

matrix

a cairo_matrix_t describing a transform to be applied to +the current font.

+cairo_set_font_options (cairo_t *cr,
+                        const cairo_font_options_t *options);
+

Sets a set of custom font rendering options for the cairo_t. +Rendering options are derived by merging these options with the +options derived from underlying surface; if the value in options + +has a default value (like CAIRO_ANTIALIAS_DEFAULT), then the value +from the surface is used.

+
+

Parameters

cr

a cairo_t

 

options

font options to use

 
+
+

+
void
+cairo_get_font_options (cairo_t *cr,
+                        cairo_font_options_t *options);
+

Retrieves font rendering options set via cairo_set_font_options. +Note that the returned options do not include any options derived +from the underlying surface; they are literally the options +passed to cairo_set_font_options().

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo_t

 

options

a cairo_font_options_t object into which to store +the retrieved options. All existing values are overwritten

void
+cairo_set_font_face (cairo_t *cr,
+                     cairo_font_face_t *font_face);
+

Replaces the current cairo_font_face_t object in the cairo_t with +font_face +. The replaced font face in the cairo_t will be +destroyed if there are no other references to it.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo_t

 

font_face

a cairo_font_face_t, or NULL to restore to the default font

+
+
+
+

cairo_get_font_face ()

+
cairo_font_face_t *
+cairo_get_font_face (cairo_t *cr);
+

Gets the current font face for a cairo_t.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo_t

 
+
+
+

Returns

+

the current font face. This object is owned by +cairo. To keep a reference to it, you must call +cairo_font_face_reference().

+

This function never returns NULL. If memory cannot be allocated, a +special "nil" cairo_font_face_t object will be returned on which +cairo_font_face_status() returns CAIRO_STATUS_NO_MEMORY. Using +this nil object will cause its error state to propagate to other +objects it is passed to, (for example, calling +cairo_set_font_face() with a nil font will trigger an error that +will shutdown the cairo_t object).

+

+
+

Since 1.0

+
+
+
+

cairo_set_scaled_font ()

+
void
+cairo_set_scaled_font (cairo_t *cr,
+                       const cairo_scaled_font_t *scaled_font);
+

Replaces the current font face, font matrix, and font options in +the cairo_t with those of the cairo_scaled_font_t. Except for +some translation, the current CTM of the cairo_t should be the +same as that of the cairo_scaled_font_t, which can be accessed +using cairo_scaled_font_get_ctm().

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo_t

 

scaled_font

a cairo_scaled_font_t

+

cairo_get_scaled_font ()

+
cairo_scaled_font_t *
+cairo_get_scaled_font (cairo_t *cr);
+

Gets the current scaled font for a cairo_t.

+
+

Parameters

+
+++++ + + + + + +

cr

a cairo_t

 
+
+
+

Returns

+

the current scaled font. This object is owned by +cairo. To keep a reference to it, you must call +cairo_scaled_font_reference().

+

This function never returns NULL. If memory cannot be allocated, a +special "nil" cairo_scaled_font_t object will be returned on which +cairo_scaled_font_status() returns CAIRO_STATUS_NO_MEMORY. Using +this nil object will cause its error state to propagate to other +objects it is passed to, (for example, calling +cairo_set_scaled_font() with a nil font will trigger an error that +will shutdown the cairo_t object).

+

+
+

Since 1.4

+
+
+
+

cairo_show_text ()

+
void
+cairo_show_text (cairo_t *cr,
+                 const char *utf8);
+

A drawing operator that generates the shape from a string of UTF-8 +characters, rendered according to the current font_face, font_size +(font_matrix), and font_options.

+

This function first computes a set of glyphs for the string of +text. The first glyph is placed so that its origin is at the +current point. The origin of each subsequent glyph is offset from +that of the previous glyph by the advance values of the previous +glyph.

+

After this call the current point is moved to the origin of where +the next glyph would be placed in this same progression. That is, +the current point will be at the origin of the final glyph offset +by its advance values. This allows for easy display of a single +logical string with multiple calls to cairo_show_text().

+

Note: The cairo_show_text() function call is part of what the cairo +designers call the "toy" text API. It is convenient for short demos +and simple programs, but it is not expected to be adequate for +serious text-using applications. See cairo_show_glyphs() for the +"real" text display API in cairo.

+
+

Parameters

+
+++++ + + + + + + + + + + + + +

cr

a cairo context

 

utf8

a NUL-terminated string of text encoded in UTF-8, or NULL

cairo_show_text_glyphs ()

+
void
+cairo_show_text_glyphs (cairo_t *cr,
+                        const char *utf8,
+                        int utf8_len,
+                        const cairo_glyph_t *glyphs,

+                        const cairo_text_cluster_t *clusters,
+                        int num_clusters,
+                        cairo_text_cluster_flags_t cluster_flags);
+

This operation has rendering effects similar to cairo_show_glyphs() +but, if the target surface supports it, uses the provided text and +cluster mapping to embed the text for the glyphs shown in the output. +If the target does not support the extended attributes, this function +acts like the basic cairo_show_glyphs() as if it had been passed +glyphs + and num_glyphs +.

+

The mapping between utf8 + and glyphs + is provided by an array of +clusters. Each cluster covers a number of +text bytes and glyphs, and neighboring clusters cover neighboring +areas of utf8 + and glyphs +. The clusters should collectively cover utf8 + +and glyphs + in entirety.

+

The first cluster always covers bytes from the beginning of utf8 +. +If cluster_flags + do not have the CAIRO_TEXT_CLUSTER_FLAG_BACKWARD +set, the first cluster also covers the beginning +of glyphs +, otherwise it covers the end of the glyphs + array and +following clusters move backward.

+

See cairo_text_cluster_t for constraints on valid clusters.

+
+

void
+cairo_font_extents (cairo_t *cr,
+                    cairo_font_extents_t *extents);
+

Gets the font extents for the currently selected font.

+
+

Parameters

void
+cairo_text_extents (cairo_t *cr,
+                    const char *utf8,
+                    cairo_text_extents_t *extents);
+

Gets the extents for a string of text. The extents describe a +user-space rectangle that encloses the "inked" portion of the text, +(as it would be drawn by cairo_show_text()). Additionally, the +x_advance and y_advance values indicate the amount by which the +current point would be advanced by cairo_show_text().

+

Note that whitespace characters do not directly contribute to the +size of the rectangle (extents.width and extents.height). They do +contribute indirectly by changing the position of non-whitespace +characters. In particular, trailing whitespace characters are +likely to not affect the size of the rectangle, though they will +affect the x_advance and y_advance values.

+
+

Parameters

Types and Values

cairo_glyph_t

+
typedef struct {
+    unsigned long        index;
+    double               x;
+    double               y;
+} cairo_glyph_t;
+
+

The cairo_glyph_t structure holds information about a single glyph +when drawing or measuring text. A font is (in simple terms) a +collection of shapes used to draw text. A glyph is one of these +shapes. There can be multiple glyphs for a single character +(alternates to be used in different contexts, for example), or a +glyph can be a ligature of multiple +characters. Cairo doesn't expose any way of converting input text +into glyphs, so in order to use the Cairo interfaces that take +arrays of glyphs, you must directly access the appropriate +underlying font system.

+

Note that the offsets given by x + and y + are not cumulative. When +drawing or measuring text, each glyph is individually positioned +with respect to the overall origin

+
+

Members

+
+++++ + + + + + + + + + + + + + + + + + +

+
typedef struct {
+    int        num_bytes;
+    int        num_glyphs;
+} cairo_text_cluster_t;
+
+

The cairo_text_cluster_t structure holds information about a single +text cluster. A text cluster is a minimal +mapping of some glyphs corresponding to some UTF-8 text.

+

For a cluster to be valid, both num_bytes + and num_glyphs + should +be non-negative, and at least one should be non-zero. +Note that clusters with zero glyphs are not as well supported as +normal clusters. For example, PDF rendering applications typically +ignore those clusters when PDF text is being selected.

+

See cairo_show_text_glyphs() for how clusters are used in advanced +text operations.

+
+

Members

+
+++++ + + + + + + + + + + + + +

+Appendix A. Creating a language binding for cairo

+

+ While cairo is implemented and C, and has a C API, it is expected + that many users of cairo will be using it from languages other + than C. The glue that connects the core cairo library to another + language is known as a language + binding. This appendix attempts to collect together + issues that come up when creating a language bindings for cairo + and present standardized solutions to promote consistency among + the different language bindings. +

+
+

+General considerations

+

+ The naming of the central cairo_t type is a + special exception. The object is “a cairo context†not “a + cairoâ€, and names such as cairo_t rather than + cairo_context_t and + cairo_set_source() rather than + cairo_context_set_source() are simply + abbreviations to make the C API more palatable. In languages + which have object-oriented syntax, this abbreviation is much + less useful. In fact, if ‘Cairo’ is used as a namespace, then + in many languages, you'd end up with a ridiculous type name + like ‘Cairo.Cairo’. For this reason, and for inter-language + consistency all object-oriented languages should name this + type as if it were cairo_context_t. +

+

+ The punctuation and casing of the type names and + method names of cairo should be changed to match the general + convention of the language. In Java, where type names are written + in StudlyCaps and method names in javaCaps, cairo_font_extents_t + will become FontExtents and + cairo_set_source(cr,source), + cr.setSource(source). + As compared to changing the punctuation, and casing, much + more reluctance should be used in changing the method names + themselves. Even if get is usually omitted from getters in + your language, you shouldn't bind cairo_get_source() as + cr.source(). +

The glue that connects the core cairo library to another + language is known as a language + binding. This appendix attempts to collect together + issues that come up when creating a language bindings for cairo + and present standardized solutions to promote consistency among + the different language bindings. + + + General considerations + + The naming of the central cairo_t type is a + special exception. The object is “a cairo context†not “a + cairoâ€, and names such as cairo_t rather than + cairo_context_t and + cairo_set_source() rather than + cairo_context_set_source() are simply + abbreviations to make the C API more palatable. In languages + which have object-oriented syntax, this abbreviation is much + less useful. In fact, if ‘Cairo’ is used as a namespace, then + in many languages, you'd end up with a ridiculous type name + like ‘Cairo.Cairo’. For this reason, and for inter-language + consistency all object-oriented languages should name this + type as if it were cairo_context_t. + + + The punctuation and casing of the type names and + method names of cairo should be changed to match the general + convention of the language. In Java, where type names are written + in StudlyCaps and method names in javaCaps, cairo_font_extents_t + will become FontExtents and + cairo_set_source(cr,source), + cr.setSource(source). + As compared to changing the punctuation, and casing, much + more reluctance should be used in changing the method names + themselves. Even if get is usually omitted from getters in + your language, you shouldn't bind cairo_get_source() as + cr.source(). + + + + Memory management + + The objects in cairo can roughly be divided into two types: + reference-counted, opaque types like + cairo_surface_t + and plain structures like + cairo_glyph_t. + cairo_path_t + and + cairo_path_data_t + are special cases and are treated separately in this appendix. + + + Refcounted opaque types all have a + ..._reference() + function to increase the refcount by one and a + ..._destroy() to decrease the refcount + by one. These should not be exposed to the user of the language + binding, but rather used to implement memory management within + the language binding. The simplest way to do memory management + for a language binding is to treat the language binding object + as a simple handle to the cairo object. The language binding + object references the cairo object, and unreferences it when + finalized. This is the recommended method, though there are + a couple of caveats to be noted: + + + + + Equality won't work as expected. You can have two language + objects for the same cairo and they won't necessarily + compare equal. If the language allows customizing the + equality operation, then this is fixable by comparing + the underlying pointers. It also can be fixed by creating + at most one language object per cairo object, and + uniquifying via a pin table (a hash + table that goes from cairo object to language object). + For cairo_surface_t you can use also + cairo_surface_set_user_data() + instead of a separate pin table. + + + + + Derivation from the language object doesn't work because + you can lose the language object while keeping the Cairo + object. Code like: + + +public class MySurface (ImageSurface) { + public MySurface (width, height) { + super (Format.ARGB32, width, height); + } + public int get42 () { + return 42; + } +} + + cr = Cairo(MySurface(width, height)); + surface = cr.getTarget(); + + + Can result in surface containing an + ImageSurface not a MySurface. + This is not easily fixable without creating memory leaks, + and it's probably best to simply forbid deriving from the + language objects. + + + + + When a plain structure is used as a return value from cairo, + this is done by passing it as a “out parameterâ€. + + +cairo_font_extents_t extents; + +cairo_font_extents (cr, &extents); + + In a language binding, this should typically be treated + as a return value: + + +FontExtents extents = cr.fontExtents (); + + A language binding has a choice in how it implements the + language objects for plain structures. It can use a pure + language object with fields corresponding to those of the C + structure, and convert from and to the C structure when calling + cairo functions or converting cairo return values. Or it + can keep a pointer to the C structure internally and wrap + it inside a language object much like occurs for refcounted + objects. The choice should be invisible to the user: they should + be able to imagine that it is implemented as a pure language + object. + + + + Multiple return values + + There are a number of functions in the cairo API that have + multiple out parameters or + in-out parameters. In some languages + these can be translated into multiple return values. In Python, + what is: + + +cairo_user_to_device (cr, &x, &y); + + can by mapped to: + + +(x, y) = cr.user_to_device (cr, x, y); + + but many languages don't have provisions for multiple return + values, so it is necessary to introduce auxiliary types. + Most of the functions that require the auxiliary types + require a type that would, in C, look like + + +typedef struct _cairo_point cairo_point_t; +struct _cairo_point { + double x; + double y; +} + + The same type should be used both for functions that use a pair + of coordinates as an absolute position, and functions that use + a pair of coordinates as a displacement.

These should be mapped to a + “rectangle†type that looks like: + + +typedef struct _cairo_rectangle cairo_rectangle_t; +struct _cairo_rectangle { + double x; + double y; + double width; + double height; +} + + The C function returns the rectangle as a set of two points to + facilitate rounding to integral extents, but this isn't worth + adding a “box†type to go along with the more obvious + “rectangle†representation. + + + Q: Would it make sense here to define a standard + cairo_rectangle_round() method + that language bindings should map? + + +void +cairo_stroke_extents (cairo_t *cr, + double *x1, double *y1, + double *x2, double *y2); + +void +cairo_fill_extents (cairo_t *cr, + double *x1, double *y1, + double *x2, double *y2); + + + + Overloading and optional arguments + + Function overloading (having a several variants of a function + with the same name and different arguments) is a language + feature available in many languages but not in C. + + + In general, language binding authors should use restraint in + combining functions in the cairo API via function + overloading. What may seem like an obvious overload now may + turn out to be strange with future additions to cairo. + It might seem logical to make + cairo_set_source_rgb() + an overload of cairo_set_source(), but future plans to add + cairo_set_source_rgb_premultiplied(), + which will also take three doubles make this a bad idea. For + this reason, only the following pairs of functions should + be combined via overloading + + +void +cairo_set_source (cairo_t *cr, cairo_pattern_t *source); + +void +cairo_set_source_surface (cairo_t *cr, + cairo_surface_t *source, + double surface_x, + double surface_y); + +void +cairo_mask (cairo_t *cr, + cairo_pattern_t *pattern); + +void +cairo_mask_surface (cairo_t *cr, + cairo_surface_t *surface, + double surface_x, + double surface_y); + +cairo_surface_t * +cairo_image_surface_create (cairo_format_t format, + int width, + int height); +cairo_surface_t * +cairo_image_surface_create_for_data (unsigned char *data, + cairo_format_t format, + int width, + int height, + int stride); + +cairo_status_t +cairo_surface_write_to_png (cairo_surface_t *surface, + const char *filename); + +cairo_status_t +cairo_surface_write_to_png_stream (cairo_surface_t *surface, + cairo_write_func_t write_func, + void *closure); + +cairo_surface_t * +cairo_image_surface_create_from_png (const char *filename); + +cairo_surface_t * +cairo_image_surface_create_from_png_stream (cairo_read_func_t read_func, + void *closure); + + + Note that there are cases where all constructors for a type + aren't overloaded together. For example + cairo_image_surface_create_from_png() + should not be overloaded together with + cairo_image_surface_create(). + In such cases, the remaining constructors will typically need to + be bound as static methods. In Java, for example, we might have: + + +Surface surface1 = ImageSurface(Format.RGB24, 100, 100); +Surface surface2 = ImageSurface.createFromPNG("camera.png"); + + Some other overloads that add combinations not found in C may be + convenient for users for language bindings that provide + cairo_point_t and cairo_rectangle_t + types, for example: + + +void +cairo_move_to (cairo_t *cr, + cairo_point_t *point); +void +cairo_rectangle (cairo_t *cr, + cairo_rectangle_t *rectangle); + + + + Streams and File I/O + + Various places in the cairo API deal with reading and writing + data, whether from and to files, or to other sources and + destinations. In these cases, what is typically provided in the + C API is a simple version that just takes a filename, and a + complex version that takes a callback function. + An example is the PNG handling functions: + + +cairo_surface_t * +cairo_image_surface_create_from_png (const char *filename); + +cairo_surface_t * +cairo_image_surface_create_from_png_stream (cairo_read_func_t read_func, + void *closure); + +cairo_status_t +cairo_surface_write_to_png (cairo_surface_t *surface, + const char *filename); + +cairo_status_t +cairo_surface_write_to_png_stream (cairo_surface_t *surface, + cairo_write_func_t write_func, + void *closure); + + The expectation is that the filename version will be mapped + literally in the language binding, but the callback version + will be mapped to a version that takes a language stream + object. For example, in Java, the four functions above + might be mapped to: + + +static public ImageSurface createFromPNG (String filename) throws IOException; +static public ImageSurface createFromPNG (InputStream stream) throws IOException; +public void writeToPNG (String filename) throws IOException; +public void writeToPNG (OutputStream stream) throws IOException; + + + In many cases, it will be better to + implement the filename version internally + using the stream version, rather than building it on top of the + filename version in C. The reason for this is that will + naturally give a more standard handling of file errors for + the language, as seen in the above Java example, where + createFromPNG() is marked as raising + an exception. Propagating exceptions from inside the callback + function to the caller will pose a challenge to the language + binding implementor, since an exception must not propagate + through the Cairo code. A technique that will be useful in + some cases is to catch the exception in the callback, + store the exception object inside a structure pointed to by + closure, and then rethrow it once + the function returns. + + + I'm not sure how to handle this for + cairo_pdf_surface_create_for_stream(). + Other than keep a “exception to rethrow†thread-specific + variable + that is checked after every call to a Cairo + function. + + + + Error handling + + The error handling approach in C for Cairo has multiple + elements: + + + + When a method on an object fails, the object is put into + an error state. Subsequent operations on the object do + nothing. The status of the object can be queried with + a function like status(). + + + Constructors, rather than + returning NULL on out-of-memory failure, + return a special singleton object on which all + operations do nothing. Retrieving the status of the + singleton object returns CAIRO_STATUS_NO_MEMORY + + + Is this going to apply to + cairo_surface_t as well? + + + What about cairo_copy_path_data()? It's probably going to + have to return NULL. + + + + Errors propagate from object to object. Setting a pattern + in an out-of-memory state as the source of a + cairo_t puts the type into an error state. + + + Much of the above is not yet implemented at the time of + this writing + + A language binding could copy the C approach, and for a + language without exceptions, this is likely the right thing + to do. However, for a language with exceptions, exposing + a completely different style of error handling for cairo + would be strange. So, instead, status should be checked + after every call to cairo, and exceptions thrown as necessary. + + + One problem that can arise with this, in languages + where handling exceptions is mandatory (like Java), is that almost + every cairo function can result in a status being set, + usually because of an out-of-memory condition. This could make + cairo hard to use. To resolve this problem, let's classify then + cairo status codes: + + +/* Memory */ +CAIRO_STATUS_NO_MEMORY, + +/* Programmer error */ +CAIRO_STATUS_INVALID_RESTORE +CAIRO_STATUS_INVALID_POP_GROUP +CAIRO_STATUS_NO_CURRENT_POINT +CAIRO_STATUS_INVALID_MATRIX +CAIRO_STATUS_NO_TARGET_SURFACE +CAIRO_STATUS_INVALID_STRING +CAIRO_STATUS_SURFACE_FINISHED +CAIRO_STATUS_BAD_NESTING + +/* Language binding implementation */ +CAIRO_STATUS_NULL_POINTER +CAIRO_STATUS_INVALID_PATH_DATA +CAIRO_STATUS_SURFACE_TYPE_MISMATCH + +/* Other */ +CAIRO_STATUS_READ_ERROR +CAIRO_STATUS_WRITE_ERROR + + + If we look at these, the + CAIRO_STATUS_NO_MEMORY + should map to the native out-of-memory exception, which could + happen at any point in any case. Most of the others indicate + programmer error, and handling them in user code would be + silly. These should be mapped into whatever the language uses + for assertion failures, rather than errors that are normally + handled. (In Java, a subclass of Error rather than Exception, + perhaps.) And CAIRO_STATUS_READ_ERROR, + and CAIRO_STATUS_WRITE_ERROR can occur + only in very specific places. (In fact, as described + in , these errors may be + mapped into the language's native I/O error types.) + So, there really aren't exceptions that the programmer must + handle at most points in the Cairo API. + + + + Patterns + + The cairo C API allows for creating a number of different types + of patterns. All of these different types of patterns map to + cairo_pattern_t + in C, but in an object oriented language, there should instead + be a hierarchy of types. (The functions that should map to + constructors or static methods for the various types are listed + after the type, methods on that type are listed below. Note that + cairo_pattern_create_rgb() and cairo_pattern_create_rgba() + should not be overloaded with each other as a SolidPattern() + constructor, but should appear as static methods instead. This + is to maintain code clarity by making it clear how the arguments + relate to color components.) + + +cairo_pattern_t + cairo_pattern_set_matrix() + cairo_pattern_get_matrix() + cairo_solid_pattern_t (cairo_pattern_create_rgb() and cairo_pattern_create_rgba()) + cairo_surface_pattern_t (cairo_pattern_create_for_surface()) + cairo_pattern_set_extend() + cairo_pattern_get_extend() + cairo_pattern_set_filter() + cairo_pattern_get_filter() + cairo_gradient_t + cairo_pattern_add_color_stop_rgb() + cairo_pattern_add_color_stop_rgba() + cairo_linear_gradient_t (cairo_pattern_create_linear()) + cairo_radial_gradient_t (cairo_pattern_create_radial()) + cairo_mesh_t (cairo_pattern_create_mesh()) + cairo_mesh_pattern_begin_patch() + cairo_mesh_pattern_end_patch() + cairo_mesh_pattern_move_to() + cairo_mesh_pattern_line_to() + cairo_mesh_pattern_curve_to() + cairo_mesh_pattern_set_control_point() + cairo_mesh_pattern_set_corner_color_rgb() + cairo_mesh_pattern_set_corner_color_rgba() + cairo_mesh_pattern_get_patch_count() + cairo_mesh_pattern_get_path() + cairo_mesh_pattern_get_control_point() + cairo_mesh_pattern_get_corner_color_rgba() + + + + + + Surfaces + + Like patterns, surfaces, which use only the + cairo_surface_t + type in the C API should be broken up into a hierarchy of types + in a language binding. + + +cairo_surface_t + cairo_image_surface_t + cairo_atsui_surface_t + cairo_win32_surface_t + cairo_xlib_surface_t + cairo_beos_surface_t + + + Unlike patterns, the constructors and methods on these types are + clearly named, and can be trivially associated with the + appropriate subtype. Many language bindings will want to avoid + binding the platform-specific subtypes at all, since the + methods on these types are not useful without passing in native + C types. Unless there is a language binding for Xlib available, + there is no way to represent a XLib Display * in + that language. + + + This doesn't mean that platform-specific surface types can't + be used in a language binding that doesn't bind the constructor. + A very common situation is to use a cairo language binding in + combination with a binding for a higher level system like + the GTK+ widget + toolkit. In such a situation, the higher level toolkit provides + ways to get references to platform specific surfaces. + + + The cairo_surface_set_user_data(), + and cairo_surface_get_user_data() + methods are provided for use in language bindings, and should + not be directly exposed to applications. One example of the use + of these functions in a language binding is creating a binding for: + + +cairo_surface_t * +cairo_image_surface_create_for_data (unsigned char *data, + cairo_format_t format, + int width, + int height, + int stride); + + + The memory block passed in for data must be + kept around until the surface is destroyed, so the language + binding must have some way of determining when that happens. The + way to do this is to use the destroy + argument to cairo_surface_set_user_data(). + + + Some languages may not have a suitable “pointer to a block of + data†type to pass in for data. And even + where a language does have such a type, the user will be + frequently able to cause the backing store to be reallocated + to a different location or truncated. Should we recommend a + standard type name and binding for a buffer object here? + + + + Fonts + + Fonts are once more an area where there is a hierarchy of types: + + +cairo_font_face_t + cairo_ft_font_face_t + cairo_win32_font_face_t +cairo_scaled_font_t + cairo_ft_scaled_font_t + cairo_win32_scaled_font_t + + + The methods on the subtypes are, however, not useful without + bindings for fontconfig and FreeType or for the Win32 GDI, + so most language bindings will choose not to bind these + types. + + + The cairo_font_face_set_user_data(), + and cairo_font_face_get_user_data() + methods are provided for use in language bindings, and should + not be directly exposed to applications. + + + + cairo_path_t + + The cairo_path_t type is one + area in which most language bindings will differ significantly + from the C API. The C API for cairo_path_t is + designed for efficiency and to avoid auxiliary objects that + would be have to be manually memory managed by the + application. However, + a language binding should not present cairo_path_t as an + array, but rather as an opaque that can be iterated + over. Different languages have quite different conventions for + how iterators work, so it is impossible to give an exact + specification for how this API should work, but the type names + and methods should be similar to the language's mapping of the following: + + +typedef struct cairo_path_iterator cairo_path_iterator_t; +typedef struct cairo_path_element cairo_path_element_t; + +cairo_path_iterator_t * +cairo_path_get_iterator (cairo_path_t *path); + +cairo_bool_t +cairo_path_iterator_has_next (cairo_path_iterator_t *iterator); + +cairo_path_element_t * +cairo_path_iterator_next (cairo_path_iterator_t *iterator); + +cairo_path_element_type_t +cairo_path_element_get_type (cairo_path_element_t *element); + +void +cairo_path_element_get_point (cairo_path_element_t *element, + int index, + double *x, + double *y); + + + The above is written using the Java conventions for + iterators. To illustrate how the API for PathIterator might + depend on the native iteration conventions of the API, examine + three versions of the loop, first written in a hypothetical Java + binding: + + +PathIterator iter = cr.copyPath().iterator(); +while (cr.hasNext()) { + PathElement element = iter.next(); + if (element.getType() == PathElementType.MOVE_TO) { + Point p = element.getPoint(0); + doMoveTo (p.x, p.y); + } +} + + And then in a hypothetical C++ binding: + + +Path path = cr.copyPath(); +for (PathIterator iter = path.begin(); iter != path.end(); iter++) { + PathElement element = *iter; + if (element.getType() == PathElementType.MOVE_TO) { + Point p = element.getPoint(0); + doMoveTo (p.x, p.y); + } +} + + And then finally in a Python binding: + + +for element in cr.copy_path(): + if element.getType == cairo.PATH_ELEMENT_MOVE_TO: + (x, y) = element.getPoint(0) + doMoveTo (x, y); + + While many of the API elements stay the same in the three + examples, the exact iteration mechanism is quite different, to + match how users of the language would expect to iterate over + a container. + + + You should not present an API for mutating or for creating new + cairo_path_t objects. In the future, these + guidelines may be extended to present an API for creating a + cairo_path_t from scratch for use with + cairo_append_path() + but the current expectation is that cairo_append_path() will + mostly be used with paths from + cairo_copy_path(). + + + + diff --git a/doc/public/tmpl/cairo-device.sgml b/doc/public/tmpl/cairo-device.sgml new file mode 100644 index

+enumcairo_device_type_t + + + + + + +Object Hierarchy + + + + + + +Description +Devices are the abstraction Cairo employs for the rendering system +used by a cairo_surface_t. You can get the device of a surface using +cairo_surface_get_device(). +Devices are created using custom functions specific to the rendering +system you want to use. See the documentation for the surface types +for those functions. +An important function that devices fulfill is sharing access to the +rendering system between Cairo and your application. If you want to +access a device directly that you used to draw to with Cairo, you must +first call cairo_device_flush() to ensure that Cairo finishes all +operations on the device and resets it to a clean state. +Cairo also provides the functions cairo_device_acquire() and +cairo_device_release() to synchronize access to the rendering system +in a multithreaded environment. This is done internally, but can also +be used by applications. +Putting this all together, a function that works with devices should +look something like this: + +void +my_device_modifying_function (cairo_device_t *device) +{ + cairo_status_t status; + + // Ensure the device is properly reset + cairo_device_flush (device); + // Try to acquire the device + status = cairo_device_acquire (device); + if (status != CAIRO_STATUS_SUCCESS) { + printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status)); + return; + } + + // Do the custom operations on the device here. + // But do not call any Cairo functions that might acquire devices. + + // Release the device when done. + cairo_device_release (device); +} + +Please refer to the documentation of each backend for +additional usage requirements, guarantees provided, and +interactions with existing surface API of the device functions for +surfaces of that type. + + + + +Functions + +cairo_device_reference () +cairo_device_reference +cairo_device_t * +cairo_device_reference (cairo_device_t *device); +Increases the reference count on device + by one. This prevents +device + from being destroyed until a matching call to +cairo_device_destroy() is made. +The number of references to a cairo_device_t can be get using +cairo_device_get_reference_count(). + +Parameters + + + + + + +device +a cairo_device_t + + + +Returns + the referenced cairo_device_t. + +Since 1.10 + +cairo_device_destroy () +cairo_device_destroy +void +cairo_device_destroy (cairo_device_t *device); +Decreases the reference count on device + by one.

Mesh patterns may also be used to create other types of +shadings that are special cases of tensor-product patch meshes such +as Coons patch meshes (type 6 shading in PDF) and Gouraud-shaded +triangle meshes (type 4 and 5 shadings in PDF). +Mesh patterns consist of one or more tensor-product patches, which +should be defined before using the mesh pattern. Using a mesh +pattern with a partially defined patch as source or mask will put +the context in an error status with a status of +CAIRO_STATUS_INVALID_MESH_CONSTRUCTION. +A tensor-product patch is defined by 4 Bézier curves (side 0, 1, 2, +3) and by 4 additional control points (P0, P1, P2, P3) that provide +further control over the patch and complete the definition of the +tensor-product patch. The corner C0 is the first point of the +patch. +Degenerate sides are permitted so straight lines may be used. A +zero length line on one side may be used to create 3 sided patches. + + C1 Side 1 C2 + +---------------+ + | | + | P1 P2 | + | | +Side 0 | | Side 2 + | | + | | + | P0 P3 | + | | + +---------------+ + C0 Side 3 C3 + +Each patch is constructed by first calling +cairo_mesh_pattern_begin_patch(), then cairo_mesh_pattern_move_to() +to specify the first point in the patch (C0). Then the sides are +specified with calls to cairo_mesh_pattern_curve_to() and +cairo_mesh_pattern_line_to(). +The four additional control points (P0, P1, P2, P3) in a patch can +be specified with cairo_mesh_pattern_set_control_point(). +At each corner of the patch (C0, C1, C2, C3) a color may be +specified with cairo_mesh_pattern_set_corner_color_rgb() or +cairo_mesh_pattern_set_corner_color_rgba(). Any corner whose color +is not explicitly specified defaults to transparent black. +A Coons patch is a special case of the tensor-product patch where +the control points are implicitly defined by the sides of the +patch. The default value for any control point not specified is the +implicit value for a Coons patch, i.e. if no control points are +specified the patch is a Coons patch. +A triangle is a special case of the tensor-product patch where the +control points are implicitly defined by the sides of the patch, +all the sides are lines and one of them has length 0, i.e. if the +patch is specified using just 3 lines, it is a triangle. If the +corners connected by the 0-length side have the same color, the +patch is a Gouraud-shaded triangle. +Patches may be oriented differently to the above diagram. For +example the first point could be at the top left. The diagram only +shows the relationship between the sides, corners and control +points. Regardless of where the first point is located, when +specifying colors, corner 0 will always be the first point, corner +1 the point between side 0 and side 1 etc. +Calling cairo_mesh_pattern_end_patch() completes the current +patch. If less than 4 sides have been defined, the first missing +side is defined as a line from the current point to the first point +of the patch (C0) and the other sides are degenerate lines from C0 +to C0. The corners between the added sides will all be coincident +with C0 of the patch and their color will be set to be the same as +the color of C0. +Additional patches may be added with additional calls to +cairo_mesh_pattern_begin_patch()/cairo_mesh_pattern_end_patch(). + +cairo_pattern_t *pattern = cairo_pattern_create_mesh (); + +/* Add a Coons patch */ +cairo_mesh_pattern_begin_patch (pattern); +cairo_mesh_pattern_move_to (pattern, 0, 0); +cairo_mesh_pattern_curve_to (pattern, 30, -30, 60, 30, 100, 0); +cairo_mesh_pattern_curve_to (pattern, 60, 30, 130, 60, 100, 100); +cairo_mesh_pattern_curve_to (pattern, 60, 70, 30, 130, 0, 100); +cairo_mesh_pattern_curve_to (pattern, 30, 70, -30, 30, 0, 0); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 0, 1, 0, 0); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 1, 0, 1, 0); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 2, 0, 0, 1); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 3, 1, 1, 0); +cairo_mesh_pattern_end_patch (pattern); + +/* Add a Gouraud-shaded triangle */ +cairo_mesh_pattern_begin_patch (pattern) +cairo_mesh_pattern_move_to (pattern, 100, 100); +cairo_mesh_pattern_line_to (pattern, 130, 130); +cairo_mesh_pattern_line_to (pattern, 130, 70); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 0, 1, 0, 0); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 1, 0, 1, 0); +cairo_mesh_pattern_set_corner_color_rgb (pattern, 2, 0, 0, 1); +cairo_mesh_pattern_end_patch (pattern) + +When two patches overlap, the last one that has been added is drawn +over the first one. +When a patch folds over itself, points are sorted depending on +their parameter coordinates inside the patch.

Comments appearing in the first two sections +apply to the entire document while comments in the BeginPageSetup +section apply only to a single page. +For comments to appear in the header section, this function should +be called after the surface is created, but before a call to +cairo_ps_surface_dsc_begin_setup(). +For comments to appear in the Setup section, this function should +be called after a call to cairo_ps_surface_dsc_begin_setup() but +before a call to cairo_ps_surface_dsc_begin_page_setup(). +For comments to appear in the PageSetup section, this function +should be called after a call to +cairo_ps_surface_dsc_begin_page_setup(). +Note that it is only necessary to call +cairo_ps_surface_dsc_begin_page_setup() for the first page of any +surface. After a call to cairo_show_page() or cairo_copy_page() +comments are unambiguously directed to the PageSetup section of the +current page.

The font selection is pretty limited too and doesn't handle the +case that the selected font does not cover the characters in the text. +This set of functions are really that, a toy text API, for testing and +demonstration purposes. Any serious application should avoid them. +The functions with glyphs in their name form cairo's +low-level text API. The low-level API relies on +the user to convert text to a set of glyph indexes and positions.

It is convenient for +short demos and simple programs, but it is not expected to be +adequate for serious text-using applications. +Selects a family and style of font from a simplified description as +a family name, slant and weight. Cairo provides no operation to +list available family names on the system (this is a "toy", +remember), but the standard CSS2 generic family names, ("serif", +"sans-serif", "cursive", "fantasy", "monospace"), are likely to +work as expected. +If family + starts with the string "cairo +:", or if no native font +backends are compiled in, cairo will use an internal font family. +The internal font family recognizes many modifiers in the family + +string, most notably, it recognizes the string "monospace". That is, +the family name "cairo +:monospace" will use the monospace version of +the internal font family. +For "real" font selection, see the font-backend-specific +font_face_create functions for the font backend you are using. (For +example, if you are using the freetype-based cairo-ft font backend, +see cairo_ft_font_face_create_for_ft_face() or +cairo_ft_font_face_create_for_pattern().) The resulting font face +could then be used with cairo_scaled_font_create() and +cairo_set_scaled_font(). +Similarly, when using the "real" font support, you can call +directly into the underlying font system, (such as fontconfig or +freetype), for operations such as listing available fonts, etc. +It is expected that most applications will need to use a more +comprehensive font handling and text layout library, (for example, +pango), in conjunction with cairo. +If text is drawn without a call to cairo_select_font_face(), (nor +cairo_set_font_face() nor cairo_set_scaled_font()), the default +family is platform-specific, but is essentially "sans-serif". +Default slant is CAIRO_FONT_SLANT_NORMAL, and default weight is +CAIRO_FONT_WEIGHT_NORMAL. +This function is equivalent to a call to cairo_toy_font_face_create() +followed by cairo_set_font_face(). + +Parameters + + + + + + +cr +a cairo_t + +family +a font family name, encoded in UTF-8 + +slant +the slant for the font + +weight +the weight for the font + + +Since 1.0 + +cairo_set_font_size () +cairo_set_font_size +void +cairo_set_font_size (cairo_t *cr, + double size); +Sets the current font matrix to a scale by a factor of size +, replacing +any font matrix previously set with cairo_set_font_size() or +cairo_set_font_matrix().

If the provided glyph array is too short for +the conversion (or for convenience), a new glyph array may be allocated +using cairo_glyph_allocate() and placed in glyphs +. Upon return, +num_glyphs + should contain the number of generated glyphs. If the value +glyphs + points at has changed after the call, the caller will free the +allocated glyph array using cairo_glyph_free(). The caller will also free +the original value of glyphs +, so the callback shouldn't do so. +The callback should populate the glyph indices and positions (in font space) +assuming that the text is to be shown at the origin. +If clusters + is not NULL, num_clusters + and cluster_flags + are also +non-NULL, and cluster mapping should be computed. The semantics of how +cluster array allocation works is similar to the glyph array. That is, +if clusters + initially points to a non-NULL value, that array may be used +as a cluster buffer, and num_clusters + points to the number of cluster +entries available there. If the provided cluster array is too short for +the conversion (or for convenience), a new cluster array may be allocated +using cairo_text_cluster_allocate() and placed in clusters +. In this case, +the original value of clusters + will still be freed by the caller. Upon +return, num_clusters + should contain the number of generated clusters. +If the value clusters + points at has changed after the call, the caller +will free the allocated cluster array using cairo_text_cluster_free(). +The callback is optional. If num_glyphs + is negative upon +the callback returning or if the return value +is CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTED, the unicode_to_glyph callback +is tried. See cairo_user_scaled_font_unicode_to_glyph_func_t. +Note: While cairo does not impose any limitation on glyph indices, +some applications may assume that a glyph index fits in a 16-bit +unsigned integer. As such, it is advised that user-fonts keep their +glyphs in the 0 to 65535 range. Furthermore, some applications may +assume that glyph 0 is a special glyph-not-found glyph.

The inherent assumption to using +this callback is that each character maps to one glyph, and that the +mapping is context independent.

To +draw with cairo, you create a cairo_t, set the target surface, +and drawing options for the cairo_t, create shapes with +functions like cairo_move_to() and cairo_line_to(), and then +draw shapes with cairo_stroke() or cairo_fill(). +cairo_t's can be pushed to a stack via cairo_save(). +They may then safely be changed, without losing the current state. +Use cairo_restore() to restore to the saved state. + + + +Functions + +cairo_create () +cairo_create +cairo_t * +cairo_create (cairo_surface_t *target); +Creates a new cairo_t with all graphics state parameters set to +default values and with target + as a target surface. The target +surface should be constructed with a backend-specific function such +as cairo_image_surface_create() (or any other +cairo_backend_surface_create() +variant). +This function references target +, so you can immediately +call cairo_surface_destroy() on it if you don't need to +maintain a separate reference to it. + +Parameters + + + + + + +target +target surface for the context + + + +Returns + a newly allocated cairo_t with a reference +count of 1. The initial reference count should be released +with cairo_destroy() when you are done using the cairo_t. +This function never returns NULL. If memory cannot be +allocated, a special cairo_t object will be returned on +which cairo_status() returns CAIRO_STATUS_NO_MEMORY. If +you attempt to target a surface which does not support +writing (such as cairo_mime_surface_t) then a +CAIRO_STATUS_WRITE_ERROR will be raised. You can use this +object normally, but no drawing will be done. + +Since 1.0 + +cairo_reference () +cairo_reference +cairo_t * +cairo_reference (cairo_t *cr); +Increases the reference count on cr + by one. This prevents +cr + from being destroyed until a matching call to cairo_destroy() +is made. +The number of references to a cairo_t can be get using +cairo_get_reference_count(). + +Parameters + + + + + + +cr +a cairo_t + + + +Returns + the referenced cairo_t. + +Since 1.0 + +cairo_destroy () +cairo_destroy +void +cairo_destroy (cairo_t *cr); +Decreases the reference count on cr + by one.

When +cairo_restore() is called, cr + will be restored to +the saved state. Multiple calls to cairo_save() and +cairo_restore() can be nested; each call to cairo_restore() +restores the state from the matching paired cairo_save(). +It isn't necessary to clear all saved states before +a cairo_t is freed. If the reference count of a cairo_t +drops to zero in response to a call to cairo_destroy(), +any saved states will be freed along with the cairo_t. + +Parameters + + + + + + +cr +a cairo_t + + +Since 1.0 + +cairo_restore () +cairo_restore +void +cairo_restore (cairo_t *cr); +Restores cr + to the state saved by a preceding call to +cairo_save() and removes that state from the stack of +saved states. + +Parameters + + + + + + +cr +a cairo_t + + +Since 1.0 + +cairo_get_target () +cairo_get_target +cairo_surface_t * +cairo_get_target (cairo_t *cr); +Gets the target surface for the cairo context as passed to +cairo_create(). +This function will always return a valid pointer, but the result +can be a "nil" surface if cr + is already in an error state, +(ie. cairo_status() != CAIRO_STATUS_SUCCESS). +A nil surface is indicated by cairo_surface_status() +!= CAIRO_STATUS_SUCCESS. + +Parameters + + + + + + +cr +a cairo context + + + +Returns + the target surface.

The redirection lasts until the group is completed by a call +to cairo_pop_group() or cairo_pop_group_to_source(). These calls +provide the result of any drawing to the group as a pattern, +(either as an explicit object, or set as the source pattern). +This group functionality can be convenient for performing +intermediate compositing. One common use of a group is to render +objects as opaque within the group, (so that they occlude each +other), and then blend the result with translucence onto the +destination. +Groups can be nested arbitrarily deep by making balanced calls to +cairo_push_group()/cairo_pop_group(). Each call pushes/pops the new +target group onto/from a stack. +The cairo_push_group() function calls cairo_save() so that any +changes to the graphics state will not be visible outside the +group, (the pop_group functions call cairo_restore()). +By default the intermediate group will have a content type of +CAIRO_CONTENT_COLOR_ALPHA.

simplest ways to run this performance suite is: + + make perf + +which will give a report of the speed of each individual test. See +more details on other options for running the suite below. + +A macro test suite (with full traces and more intensive benchmarks) is +also available; for this, see http://cgit.freedesktop.org/cairo-traces. +The macro-benchmarks are better measures of actual real-world +performance, and should be preferred over the micro-benchmarks (and over +make perf) for identifying performance regressions or improvements. If +you copy or symlink this repository at cairo/perf/cairo-traces, then +make perf will run those tests as well. + +Running the micro-benchmarks +---------------------------- +The micro-benchmark performance suite is composed of a series of +hand-written, short, synthetic tests that measure the speed of doing a +simple operation such as painting a surface or showing glyphs. These aim +to give very good feedback on whether a performance related patch is +successful without causing any performance degradations elsewhere. + +The micro-benchmarks are compiled into a single executable called +cairo-perf-micro, which is what "make perf" executes. Some +examples of running it: + + # Report on all tests with default number of iterations: + ./cairo-perf-micro + + # Report on 100 iterations of all gradient tests: + ./cairo-perf-micro -i 100 gradient + + # Generate raw results for 10 iterations into cairo.perf + ./cairo-perf-micro -r -i 10 > cairo.perf + # Append 10 more iterations of the paint test + ./cairo-perf-micro -r -i 10 paint >> cairo.perf + +Raw results aren't useful for reading directly, but are quite useful +when using cairo-perf-diff to compare separate runs (see more +below). The advantage of using the raw mode is that test runs can be +generated incrementally and appended to existing reports. + +Generating comparisons of separate runs +--------------------------------------- +It's often useful to generate a chart showing the comparison of two +separate runs of the cairo performance suite, (for example, after +applying a patch intended to improve cairo's performance). The +cairo-perf-diff script can be used to compare two report files +generated by cairo-perf. + +Again, by way of example: + + # Show performance changes from cairo-orig.perf to cairo-patched.perf + ./cairo-perf-diff cairo-orig.perf cairo-patched.perf + +This will work whether the data files were generate in raw mode (with +cairo-perf -r) or cooked, (cairo-perf without -r). + +Finally, in its most powerful mode, cairo-perf-diff accepts two git +revisions and will do all the work of checking each revision out, +building it, running cairo-perf for each revision, and finally +generating the report. Obviously, this mode only works if you are +using cairo within a git repository, (and not from a tar file). Using +this mode is as simple as passing the git revisions to be compared to +cairo-perf-diff: + + # Compare cairo 1.2.6 to cairo 1.4.0 + ./cairo-perf-diff 1.2.6 1.4.0 + + # Measure the impact of the latest commit + ./cairo-perf-diff HEAD~1 HEAD + +As a convenience, this common desire to measure a single commit is +supported by passing a single revision to cairo-perf-diff, in which +case it will compare it to the immediately preceding commit. So for +example: + + # Measure the impact of the latest commit + ./cairo-perf-diff HEAD + + # Measure the impact of an arbitrary commit by SHA-1 + ./cairo-perf-diff aa883123d2af90 + +Also, when passing git revisions to cairo-perf-diff like this, it will +automatically cache results and re-use them rather than re-running +cairo-perf over and over on the same versions. This means that if you +ask for a report that you've generated in the past, cairo-perf-diff +should return it immediately. + +Now, sometimes it is desirable to generate more iterations rather than +re-using cached results. In this case, the -f flag can be used to +force cairo-perf-diff to generate additional results in addition to +what has been cached: + + # Measure the impact of latest commit (force more measurement) + ./cairo-perf-diff -f + +And finally, the -f mode is most useful in conjunction with the -- +option to cairo-perf-diff which allows you to pass options to the +underlying cairo-perf runs. This allows you to restrict the additional +test runs to a limited subset of the tests. + +For example, a frequently used trick is to first generate a chart with +a very small number of iterations for all tests: + + ./cairo-perf-diff HEAD + +Then, if any of the results look suspicious, (say there's a slowdown +reported in the text tests, but you think the text test shouldn't be +affected), then you can force more iterations to be tested for only +those tests: + + ./cairo-perf-diff -f HEAD -- text + +Generating comparisons of different backends +-------------------------------------------- +An alternate question that is often asked is, "how does the speed of one +backend compare to another?". cairo-perf-compare-backends can read files +generated by cairo-perf and produces a comparison of the backends for every +test. + +Again, by way of example: + + # Show relative performance of the backends + ./cairo-perf-compare-backends cairo.perf + +This will work whether the data files were generate in raw mode (with +cairo-perf -r) or cooked, (cairo-perf without -r). + + +Creating a new performance test +------------------------------- +This is where we could use everybody's help. If you have encountered a +sequence of cairo operations that are slower than you would like, then +please provide a performance test. Writing a test is very simple, it +requires you to write only a small C file with a couple of functions, +one of which exercises the cairo calls of interest. + +Here is the basic structure of a performance test file: + + /* Copyright © 2006 Kind Cairo User + * + * ... Licensing information here ... + * Please copy the MIT blurb as in other tests + */ + + #include "cairo-perf.h" + + static cairo_time_t + do_my_new_test (cairo_t *cr, int width, int height) + { + cairo_perf_timer_start (); + + /* Make the cairo calls to be measured */ + + cairo_perf_timer_stop (); + + return cairo_perf_timer_elapsed (); + } + + void + my_new_test (cairo_perf_t *perf, cairo_t *cr, int width, int height) + { + /* First do any setup for which the execution time should not + * be measured. For example, this might include loading + * images from disk, creating patterns, etc. */ + + /* Then launch the actual performance testing. */ + cairo_perf_run (perf, "my_new_test", do_my_new_test); + + /* Finally, perform any cleanup from the setup above. */ + } + +That's really all there is to writing a new test. The first function +above is the one that does the real work and returns a timing +number. The second function is the one that will be called by the +performance test rig (see below for how to accomplish that), and +allows for multiple performance cases to be written in one file, +(simply call cairo_perf_run once for each case, passing the +appropriate callback function to each). + +We go through this dance of indirectly calling your own function +through cairo_perf_run so that cairo_perf_run can call your function +many times and measure statistical properties over the many runs. + +Finally, to fully integrate your new test case you just need to add +your new test to three different lists. (TODO: We should set this up +better so that the lists are maintained automatically---computed from +the list of files in cairo/perf, for example). Here's what needs to be +added: + + 1. Makefile.am: Add the new file name to the cairo_perf_SOURCES list + + 2. cairo-perf.h: Add a new CAIRO_PERF_DECL line with the name of your + function, (my_new_test in the example above) + + 3. cairo-perf-micro.c: Add a new row to the list at the end of the + file. A typical entry would look like: + + { my_new_test, 16, 64 } + + The last two numbers are a minimum and a maximum image size at + which your test should be exercised. If these values are the same, + then only that size will be used. If they are different, then + intermediate sizes will be used by doubling. So in the example + above, three tests would be performed at sizes of 16x16, 32x32 and + 64x64. + + +How to run cairo-perf-diff on WINDOWS +------------------------------------- +This section explains the specifics of running cairo-perf-diff under +win32 plateforms. It assumes that you have installed a UNIX-like shell +environment such as MSYS (distributed as part of MinGW). + + 1.

cairo library. + + +Source Code Listing +------------------- + +The canonical list of source files is the file Makefile.sources. See that +file for how it works. + + +New Backends +------------ + +The rule of the thumb for adding new backends is to see how other +backends are integrated. Pick one of the simpler, unsupported, backends +and search the entire tree for it, and go from there. + +To add new backends you need to basically: + + * Modify $(top_srcdir)/configure.in to add checks for your backend. + + * Modify Makefile.sources to add source files for your backend, + + * Modify $(top_srcdir)/boilerplate/ to add boilerplate code for + testing your new backend. + + +New API +------- + +After adding new API, run "make check" in this directory and fix any +reported issues. Also add new API to the right location in +$(top_srcdir)/doc/public/cairo-sections.txt and run "make check" +in $(top_builddir)/doc/public to make sure that any newly added +documentation is correctly hooked up. + +Do not forget to add tests for the new API. See next section. + + +Tests +----- + +There are some tests in this directory that check the source code and +the build for various issues. The tests are very quick to run, and +particularly should be run after any documentation or API changes. It +does not hurt to run them after any source modification either. Run +them simply by calling: + + make check + +There are also extensive regression tests in $(top_srcdir)/test. It is +a good idea to run that test suite for any changes made to the source +code. Moreover, for any new feature, API, or bug fix, new tests should +be added to the regression test suite to test the new code. + + +Bibliography +------------ + +A detailed list of academic publications used in cairo code is available +in the file $(top_srcdir)/BIBLIOGRAPHY. Feel free to update as you +implement more papers. + +For more technical publications (eg. Adobe technical reports) just +point them out in a comment in the header of the file implementing them. + diff --git a/src/cairo-analysis-surface-private.h b/src/cairo-analysis-surface-private.h new file mode 100644 index 000000000..1e054c209 --- /dev/null +++ b/src/cairo-analysis-surface-private.h @@ -0,0 +1,74 @@ +/* + * Copyright © 2005 Keith Packard + * + * This library is free software; you can redistribute it and/or + * modify it either under the terms of the GNU Lesser General Public + * License version 2.1 as published by the Free Software Foundation + * (the "LGPL") or, at your option, under the terms of the Mozilla + * Public License Version 1.1 (the "MPL").

This one works in two phases: + * gathering edges and generating spans. + * + * 1) As the user feeds the scan converter edges they are vertically + * clipped and bucketted into a _polygon_ data structure. The edges + * are also snapped from the user's coordinates to the subpixel grid + * coordinates used during scan conversion. + * + * user + * | + * | edges + * V + * polygon buckets + * + * 2) Generating spans works by performing a vertical sweep of pixel + * rows from top to bottom and maintaining an _active_list_ of edges + * that intersect the row. From the active list the fill rule + * determines which edges are the left and right edges of the start of + * each span, and their contribution is then accumulated into a pixel + * coverage list (_cell_list_) as coverage deltas. Once the coverage + * deltas of all edges are known we can form spans of constant pixel + * coverage by summing the deltas during a traversal of the cell list. + * At the end of a pixel row the cell list is sent to a coverage + * blitter for rendering to some target surface. + * + * The pixel coverages are computed by either supersampling the row + * and box filtering a mono rasterisation, or by computing the exact + * coverages of edges in the active list.

How about PictOpOutReverse, + * which has a source factor of 0 and dest factor of (1 - source alpha). We + * can get the source alpha value (srca.X = src.A * mask.X) out of the texture + * blenders pretty easily. So we can do a component-alpha OutReverse, which + * gets us: + * + * dst.A = 0 + (1 - (src.A * mask.A)) * dst.A + * dst.R = 0 + (1 - (src.A * mask.R)) * dst.R + * dst.G = 0 + (1 - (src.A * mask.G)) * dst.G + * dst.B = 0 + (1 - (src.A * mask.B)) * dst.B + * + * OK. And if an op doesn't use the source alpha value for the destination + * factor, then we can do the channel multiplication in the texture blenders + * to get the source value, and ignore the source alpha that we wouldn't use. + * We've supported this in the Radeon driver for a long time.

+ * it is easy to get confused about what's going on. + * + * The user's view + * --------------- + * + * Users ask for things in user space. When cairo starts, a user space unit + * is about 1/96 inch, which is similar to (but importantly different from) + * the normal "point" units most users think in terms of. When a user + * selects a font, its scale is set to "one user unit". The user can then + * independently scale the user coordinate system *or* the font matrix, in + * order to adjust the rendered size of the font. + * + * Metrics are returned in user space, whether they are obtained from + * the currently selected font in a #cairo_t or from a #cairo_scaled_font_t + * which is a font specialized to a particular scale matrix, CTM, and target + * surface. + * + * The font's view + * --------------- + * + * Fonts are designed and stored (in say .ttf files) in "font space", which + * describes an "EM Square" (a design tile) and has some abstract number + * such as 1000, 1024, or 2048 units per "EM". This is basically an + * uninteresting space for us, but we need to remember that it exists. + * + * Font resources (from libraries or operating systems) render themselves + * to a particular device. Since they do not want to make most programmers + * worry about the font design space, the scaling API is simplified to + * involve just telling the font the required pixel size of the EM square + * (that is, in device space). + * + * + * Cairo's gstate view + * ------------------- + * + * In addition to the CTM and CTM inverse, we keep a matrix in the gstate + * called the "font matrix" which describes the user's most recent + * font-scaling or font-transforming request. This is kept in terms of an + * abstract scale factor, composed with the CTM and used to set the font's + * pixel size. So if the user asks to "scale the font by 12", the matrix + * is: + * + * [ 12.0, 0.0, 0.0, 12.0, 0.0, 0.0 ] + * + * It is an affine matrix, like all cairo matrices, where its tx and ty + * components are used to "nudging" fonts around and are handled in gstate + * and then ignored by the "scaled-font" layer. + * + * In order to perform any action on a font, we must build an object + * called a #cairo_font_scale_t; this contains the central 2x2 matrix + * resulting from "font matrix * CTM" (sans the font matrix translation + * components as stated in the previous paragraph). + * + * We pass this to the font when making requests of it, which causes it to + * reply for a particular [user request, device] combination, under the CTM + * (to accommodate the "zoom in" == "bigger fonts" issue above). + * + * The other terms in our communication with the font are therefore in + * device space. When we ask it to perform text->glyph conversion, it will + * produce a glyph string in device space. Glyph vectors we pass to it for + * measuring or rendering should be in device space. The metrics which we + * get back from the font will be in device space. The contents of the + * global glyph image cache will be in device space. + * + * + * Cairo's public view + * ------------------- + * + * Since the values entering and leaving via public API calls are in user + * space, the gstate functions typically need to multiply arguments by the + * CTM (for user-input glyph vectors), and return values by the CTM inverse + * (for font responses such as metrics or glyph vectors). + * + */ + +static cairo_status_t +_cairo_gstate_ensure_font_face (cairo_gstate_t *gstate) +{ + cairo_font_face_t *font_face;

The unit + circle on which X is constrained is to be parameterized by t: + + X(θ) = (cos(θ), sin(θ)) + + Thus + + X'(θ) = X(θ) * _R_ = (cos(θ), sin(θ)) * [a b] + [c d] + = (a*cos(θ) + c*sin(θ), b*cos(θ) + d*sin(θ)). + + Define + + r(θ) = |X'(θ)| + + Thus + + r²(θ) = (a*cos(θ) + c*sin(θ))² + (b*cos(θ) + d*sin(θ))² + = (a² + b²)*cos²(θ) + (c² + d²)*sin²(θ) + + 2*(a*c + b*d)*cos(θ)*sin(θ) + + Now apply the double angle formulae (A) to (C) from above: + + r²(θ) = (a² + b² + c² + d²)/2 + + (a² + b² - c² - d²)*cos(2*θ)/2 + + (a*c + b*d)*sin(2*θ) + = f + g*cos(φ) + h*sin(φ) + + Where + + f = (a² + b² + c² + d²)/2 + g = (a² + b² - c² - d²)/2 + h = (a*c + d*d) + φ = 2*θ + + It is clear that MAX[ |X'| ] = sqrt(MAX[ r² ]).

Sketch of proof (from Popescu and Rosen): + * + * Let's take the P pixel we're interested into.

If they are all in different regions, they can't + * satisfy the distance constraint.

Example: + * + * application window + * +---------------+ + * | . | + * | (x,y). | + * |......+---+ | + * | | | <--|-- expose area + * | +---+ | + * +---------------+ + * + * In this case, the user of cairo API can set the device_space on + * the expose area to (-x,-y) to move the device space origin to that + * of the application window, such that drawing in the expose area + * surface and painting it in the application window has the same + * effect as drawing in the application window directly. Gtk+ has + * been using this feature. + * + * - Glyph surfaces: In most font rendering systems, glyph surfaces + * have an origin at (0,0) and a bounding box that is typically + * represented as (x_bearing,y_bearing,width,height). Depending on + * which way y progresses in the system, y_bearing may typically be + * negative (for systems similar to cairo, with origin at top left), + * or be positive (in systems like PDF with origin at bottom left). + * No matter which is the case, it is important to note that + * (x_bearing,y_bearing) is the coordinates of top-left of the glyph + * relative to the glyph origin.

This one works in two phases: + * gathering edges and generating spans. + * + * 1) As the user feeds the scan converter edges they are vertically + * clipped and bucketted into a _polygon_ data structure. The edges + * are also snapped from the user's coordinates to the subpixel grid + * coordinates used during scan conversion. + * + * user + * | + * | edges + * V + * polygon buckets + * + * 2) Generating spans works by performing a vertical sweep of pixel + * rows from top to bottom and maintaining an _active_list_ of edges + * that intersect the row. From the active list the fill rule + * determines which edges are the left and right edges of the start of + * each span, and their contribution is then accumulated into a pixel + * coverage list (_cell_list_) as coverage deltas. Once the coverage + * deltas of all edges are known we can form spans of constant pixel + * coverage by summing the deltas during a traversal of the cell list. + * At the end of a pixel row the cell list is sent to a coverage + * blitter for rendering to some target surface. + * + * The pixel coverages are computed by either supersampling the row + * and box filtering a mono rasterisation, or by computing the exact + * coverages of edges in the active list.

This one works in two phases: + * gathering edges and generating spans. + * + * 1) As the user feeds the scan converter edges they are vertically + * clipped and bucketted into a _polygon_ data structure. The edges + * are also snapped from the user's coordinates to the subpixel grid + * coordinates used during scan conversion. + * + * user + * | + * | edges + * V + * polygon buckets + * + * 2) Generating spans works by performing a vertical sweep of pixel + * rows from top to bottom and maintaining an _active_list_ of edges + * that intersect the row. From the active list the fill rule + * determines which edges are the left and right edges of the start of + * each span, and their contribution is then accumulated into a pixel + * coverage list (_cell_list_) as coverage deltas. Once the coverage + * deltas of all edges are known we can form spans of constant pixel + * coverage by summing the deltas during a traversal of the cell list. + * At the end of a pixel row the cell list is sent to a coverage + * blitter for rendering to some target surface. + * + * The pixel coverages are computed by either supersampling the row + * and box filtering a mono rasterisation, or by computing the exact + * coverages of edges in the active list.

This is perhaps a good thing since we also neglected to fix + * up things like cairo_surface_write_to_png() for the new format + * (-Wswitch-enum will tell you where). Is it obvious that format was + * added in haste? + * + * The reason for the new format was to allow the xlib backend to be + * used on X servers with a 565 visual. So the new format did its job + * for that, even without being considered "valid" for the sake of + * things like cairo_image_surface_create(). + * + * Since 1.2.0 we ran into the same situtation with X servers with BGR + * visuals. This time we invented #cairo_internal_format_t instead, + * (see it for more discussion). + * + * The punchline is that %CAIRO_FORMAT_VALID must not conside any + * internal format to be valid. Also we need to decide if the + * RGB16_565 should be moved to instead be an internal format. If so, + * this macro need not change for it. (We probably will need to leave + * an RGB16_565 value in the header files for the sake of code that + * might have that value in it.) + * + * If we do decide to start fully supporting RGB16_565 as an external + * format, then %CAIRO_FORMAT_VALID needs to be adjusted to include + * it.

test should be as simple as running: + + make test + +assuming that the cairo distribution in the directory above has been +configured and built. The test suite here goes through some effort to +run against the locally compiled library rather than any installed +version, but those efforts may fall short depending on the level of your +libtool madness. + +The results of the test suite run are summarized in an index.html +file, which, when viewed in a web browser makes it quite easy to +visually see any failed renderings alongside the corresponding +reference image, (and a diff image as well). + +The test suite needs to be run before any code is committed and before +any release. See below for hints and rules governing the use of the suite. + +The test suite is built as a single binary, which allows you to choose +individual or categories of tests to run. For example, if you want to +run all text related tests you can use: + ./cairo-test-suite text +Or if you want to check the current status of known failures: + ./cairo-test-suite XFAIL +Or to run a subset of tests, use the -k option to run only the tests +that include the given keyword: + ./cairo-test-suite -k downscale +The binary also permits controlling which backend is used via the +CAIRO_TEST_TARGET environment variable, so for instance: + CAIRO_TEST_TARGET=gl ./cairo-test-suite -k blur +This binary should be backwards-compatible with all library versions, +allowing you to compare current versus past behaviour for any test. + +Tailoring tests running +----------------------- +There are some mechanisms to limit the tests run during "make test". +These come very handy when doing development, but should not be used +to circumvent the "pass" requirements listed below. + +make's TARGETS environment variable can be used to limit the backends when +running the tests. It should contain a (space-, comma-separated) list of +backends. CAIRO_TESTS environment variable, which is a comma-, space-seperated +lists, can be used to limit the tests run. +For example: + + CAIRO_TESTS="zero-alpha" make test TARGETS=image,ps + +make's FORMAT variable can also be used to limit the content formats when +running the tests. It should contain a (space-, comma-separated) list of +content formats to test. +For example: + + CAIRO_TESTS="zero-alpha" make test TARGETS=image,ps FORMAT="rgb,rgba" + +Another very handy mechanism when trying to fix bugs is: + + make retest + +This will re-run the test suite, but only on tests that failed on the +last run. So this is a much faster way of checking if changes actually +fix bugs rather than running the entire test suite again. + +The test suite first compares the output from the current run against the +previous in order to skip more expensive image comparisons . If you think +this is interfering with the results, you can clear the cached results using: + + make clean-caches + +Running tests under modified environments or tools +------------------------------------------------- +To run tests under a tool like gdb, one can use the run target and +the TOOL variable. For example: + + CAIRO_TESTS=user-font make run TOOL=gdb TARGETS=pdf + +If you want to run under valgrind, there is a specific target for that +that also sets a bunch of useful valgrind options. Try: + + CAIRO_TESTS=user-font make check-valgrind + +You can run tests under a modified environment you can use the ENV +make variable. However, that environment will also affect the libtool +wrapper of the tests. To only affect the actual test binaries, pass +such environment as TOOL: + + CAIRO_TESTS=user-font make run TOOL="LD_PRELOAD=/path/to/something.so" + +Getting the elusive zero failures +--------------------------------- +It's generally been very difficult to achieve a test run with zero +failures. The difficulties stem from the various versions of the many +libraries that the test suite depends on, (it depends on a lot more +than cairo itself), as well as fonts and other system-specific +settings. If your system differs significantly from the system on +which the reference images were generated, then you will likely see +the test suite reporting "failures", (even if cairo is working just +fine). + +We are constantly working to reduce the number of variables that need +to be tweaked to get a clean run, (for example, by bundling fonts with +the test suite itself), and also working to more carefully document +the software configuration used to generate the reference images. + +Here are some of the relevant details: + + * Your system must have a copy of the DejaVu font, the sha1sum of + the version used are listed in [...]. These are + "DejaVu Sans" (DejaVuSans.ttf) [1cd336329f45f241002ded61893d91e3acd04436]; + "DejaVu Sans Mono" (DejaVuSansMono.ttf) [0458c0f0fb57f3eb8ced62f26fe7c5ed4e6a9a68]; + "DejaVu Serif" (DejaVuSerif.ttf) [93502d0d0445d1fe1c9f51e51b3e0169266346ce]; + [the DejaVu fonts can be installed from the ttf-dejavu 2.33-2 Debian package] + and also + "Nimbus Sans L" (n019003l.pfb) + [which can be found in the gsfonts Debian package]. + + * Currently, you must be using a build of cairo using freetype + (cairo-ft) as the default font backend. Otherwise all tests + involving text are likely to fail. + + * To test the pdf backend, you will want the very latest version of + poppler as made available via git: + + git clone git://anongit.freedesktop.org/git/poppler/poppler + + As of this writing, no released version of poppler contains all + the fixes you will need to avoid false negatives from the test + suite. + + * To test the ps backend, you will need ghostscript version 9.04. + + * Testing the xlib backend is problematic since many X server + drivers have bugs that are exercised by the test suite. (Or, if + not actual bugs, differ slightly in their output in such a way + that the test suite will report errors.) This can be quite handy + if you want to debug an X server driver, but since most people + don't want to do that, another option is to run against a headless + X server that uses only software for all rendering. One such X + server is Xvfb which can be started like this: + + Xvfb -screen 0 1680x1024x24 -ac -nolisten tcp :2 + + after which the test suite can be run against it like so: + + DISPLAY=:2 make test + + We have been using Xvfb for testing cairo releases and ensuring + that all tests behave as expected with this X server. + +What if I can't make my system match? +------------------------------------- +For one reason or another, you may be unable to get a clean run of the +test suite even if cairo is working properly, (for example, you might +be on a system without freetype). In this case, it's still useful to +be able to determine if code changes you make to cairo result in any +regressions to the test suite. But it's hard to notice regressions if +there are many failures both before and after your changes. + +For this scenario, you can capture the output of a run of the test +suite before your changes, and then use the CAIRO_REF_DIR environment +variable to use that output as the reference images for a run after +your changes. The process looks like this: + + # Before code change there may be failures we don't care about + make test + + # Let's save those output images + mkdir /some/directory/ + cp -r test/output /some/directory/ + + # hack, hack, hack + + # Now to see if nothing changed: + CAIRO_REF_DIR=/some/directory/ make test + +Best practices for cairo developers +=================================== +If we all follow the guidelines below, then both the test suite and +cairo itself will stay much healthier, and we'll all have a lot more +fun hacking on cairo. + +Before committing +----------------- +All tests should return a result of PASS or XFAIL. The XFAIL results +indicate known bugs. The final message should be one of the following: + + All XX tests behaved as expected (YY expected failures) + All XX tests passed + +If any tests have a status of FAIL, then the new code has caused a +regression error which should be fixed before the code is committed. + +When a new bug is found +----------------------- +A new test case should be added by imitating the style of an existing +test. This means adding the following files: + + new-bug.c + reference/new-bug.ref.png + reference/new-bug.xfail.png + +Where new-bug.c is a minimal program to demonstrate the bug, following +the style of existing tests. The new-bug.ref.png image should contain +the desired result of new-bug.c if the bug were fixed while +new-bug.xfail.png contains the current results of the test. + +Makefile.sources should be edited by adding new-bug.c to test_sources. +And last but not least, don't forget to "git add" the new files. + +When a new feature is added +--------------------------- +It's important for the regression suite to keep pace with development +of the library. So a new test should be added for each new feature. +The work involved is similar the work described above for new bugs. +The only distinction is that the test is expected to pass so it +should not need a new-bug.xfail.png file. + +While working on a test +----------------------- +Before a bugfix or feature is ready, it may be useful to compare +output from different builds. For convenience, you can set +CAIRO_REF_DIR to point at a previous test directory, relative +to the current test directory, and any previous output will be +used by preference as reference images. + +When a bug is fixed +------------------- +The fix should be verified by running the test suite which should +result in an "unexpected pass" for the test of interest. Rejoice as +appropriate, then remove the relevant xfail.png file from git. + +Before releasing +---------------- +All tests should return a result of PASS for all supported (those enabled by +default) backends, meaning all known bugs are fixed, resulting in the happy +message: + + All XX tests passed + +Some notes on limitations in poppler +==================================== +One of the difficulties of our current test infrastructure is that we +rely on external tools to convert cairo's vector output (PDF, +PostScript, and SVG), into an image that can be used for the image +comparison. This means that any bugs in that conversion tool will +result in false negatives in the test suite. + +We've identified several such bugs in the poppler library which is +used to convert PDF to an image. This is particularly discouraging +because 1) poppler is free software that will be used by *many* cairo +users, and 2) poppler calls into cairo for its rendering so it should +be able to do a 100% faithful conversion. + +So we have an interest in ensuring that these poppler bugs get fixed +sooner rather than later. As such, we're trying to be good citizens by +reporting all such poppler bugs that we identify to the poppler +bugzilla. Here's a tracking bug explaining the situation: + + Poppler does not yet handle everything in the cairo test suite + https://bugs.freedesktop.org/show_bug.cgi?id=12143 + +Here's the rule: If a cairo-pdf test reports a failure, but viewing +the resulting PDF file with acroread suggests that the PDF itself is +correct, then there's likely a bug in poppler. In this case, we can +simply report the poppler bug, (making it block 12143 above), post the +PDF result from the test suite, and list the bug in this file. Once +we've done this, we can capture poppler's buggy output as a +pdf-specific reference image (as reference/*.xfail.png) so that the +test suite will regard the test as passing, (and we'll ensure there +is no regression). + +Once the poppler bug gets fixed, the test suite will start reporting a +false negative again, and this will be easy to fix by simply removing +the pdf-specific reference image. + +Here are the reported poppler bugs and the tests they affect: + +Poppler doesn't correctly handle gradients with transparency +https://bugs.freedesktop.org/show_bug.cgi?id=12144 +-------------------------------------------------- +fill-alpha-pattern +gradient-alpha +gradient-constant-alpha +linear-gradient +linear-gradient-reflect +radial-gradient +trap-clip + +Poppler should paint images with CAIRO_EXTEND_PAD +https://bugs.freedesktop.org/show_bug.cgi?id=14578 +-------------------------------------------------- +paint-source-alpha +paint-with-alpha +rotate-image-surface-paint +scale-source-surface-paint + +Incorrect clipping of group object (regression?) +https://bugs.freedesktop.org/show_bug.cgi?id=14580 +-------------------------------------------------- +push-group + +spurious horizontal stripes in color gradients +https://bugs.freedesktop.org/show_bug.cgi?id=10942 +-------------------------------------------------- +smask +smask-fill +smask-image-mask +smask-mask +smask-paint +smask-stroke +smask-text + +Ghostscript does not correctly render small miters +http://bugs.ghostscript.com/show_bug.cgi?id=690098 +-------------------------------------------------- +miter-precision diff --git a/test/a1-bug.c b/test/a1-bug.c new file mode 100644 index 000000000..8e00d40e3 --- /dev/null +++ b/test/a1-bug.c @@ -0,0 +1,61 @@ +/* + * Permission is hereby granted, free of charge, to any person + * obtaining a copy of this software and associated documentation + * files (the "Software"), to deal in the Software without + * restriction, including without limitation the rights to use, copy, + * modify, merge, publish, distribute, sublicense, and/or sell copies + * of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + * NONINFRINGEMENT.

It does this by calling all APIs that take + * surfaces or contexts and calling them on specially prepared arguments that + * should fail when called on this function. + * + * ADDING NEW FUNCTIONS + * + * You need (for adding the function cairo_surface_foo): + * 1) A surface_test_func_t named test_cairo_surface_foo that gets passed the + * prepared surface and has the job of calling the function and checking + * the return value (if one exists) for correctness. The top of this file + * contains all these shim functions. + * 2) Knowledge if the function behaves like a setter or like a getter. A + * setter should set an error status on the surface, a getter does not + * modify the function. + * 3) Knowledge if the function only works for a specific surface type and for + * which one. + * 4) An entry in the tests array using the TEST() macro. It takes as arguments: + * - The function name + * - TRUE if the function modifies the surface, FALSE otherwise + * - the surface type for which the function is valid or -1 if it is valid + * for all surface types. + * + * FIXING FAILURES + * + * The test will dump failures notices into the api-special-cases.log file (when + * it doesn't crash). These should be pretty self-explanatory. Usually it is + * enough to just add a new check to the function it complained about. + */ + +#ifdef HAVE_CONFIG_H +#include "config.h" +#endif + +#include +#include + +#include "cairo-test.h" + +#if CAIRO_HAS_GL_SURFACE +#include +#endif +#if CAIRO_HAS_OS2_SURFACE +#include +#endif +#if CAIRO_HAS_PDF_SURFACE +#include +#endif +#if CAIRO_HAS_PS_SURFACE +#include +#endif +#if CAIRO_HAS_QUARTZ_SURFACE +#define Cursor QuartzCursor +#include +#undef Cursor +#endif +#if CAIRO_HAS_SVG_SURFACE +#include +#endif +#if CAIRO_HAS_TEE_SURFACE +#include +#endif +#if CAIRO_HAS_XCB_SURFACE +#include +#endif +#if CAIRO_HAS_XLIB_SURFACE +#define Cursor XCursor +#include +#undef Cursor +#endif + +#define surface_has_type(surface,type) (cairo_surface_get_type (surface) == (type)) + +typedef cairo_test_status_t (* surface_test_func_t) (cairo_surface_t *surface); +typedef cairo_test_status_t (* context_test_func_t) (cairo_t *cr); + +static cairo_test_status_t +test_cairo_reference (cairo_t *cr) +{ + cairo_destroy (cairo_reference (cr)); + + return CAIRO_TEST_SUCCESS; +} + +static cairo_test_status_t +test_cairo_get_reference_count (cairo_t *cr) +{ + unsigned int refcount = cairo_get_reference_count (cr); + if (refcount > 0) + return CAIRO_TEST_SUCCESS; + /* inert error context have a refcount of 0 */ + return cairo_status (cr) ?

Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

A smaller surface could be used, but I fear that at some + * point the off-surface glyph drawing would be optimized away + * and not exercise the bug. + * + * So, to keep the surface size under control, I use + * cairo_show_glyphs which allows me to place the glyphs all on + * top of each other. But, since cairo doesn't provide any + * character-to-glyphs mapping, I can't get a reliable glyph + * index (for character 'x' for example). So I just "guess" a + * glyph index and use white-on-white drawing to ignore the + * result.

The PNG file looks fine, the text on the drawable is + * unreadable. + * + * Steve + * + * 2004-11-03 Carl Worth + * + * Looks like the major problems with this bug appeared in the great + * font rework between 0.1.23 and 0.2.0. And it looks like we need + * to fix the regression test suite to test the xlib target (since + * the bug does not show up in the png backend). + * + * Hmm... Actually, things don't look perfect even in the PNG + * output. Look at how that 'o' moves around. It's particularly off + * in the case where it's rotated by PI. + * + * And I'm still not sure about what to do for test cases with + * text--a new version of freetype will change everything. We may + * need to add a simple backend for stroked fonts and add a simple + * builtin font to cairo for pixel-perfect tests with text. + * + * 2005-08-23 + * + * It appears that the worst placement and glyph selection problems + * have now been resolved. In the past some letters were noticeably + * of a different size at some rotations, and there was a lot of + * drift away from the baseline. These problems do not appear + * anymore. + * + * Another thing that helps is that we now have font options which + * we can use to disable hinting in order to get more repeatable + * results. I'm doing that in this test now. + * + * There are still some subtle positioning problems which I'm + * assuming are due to the lack of finer-than-whole-pixel glyph + * positioning. I'm generating a reference image now by replacing + * cairo_show_text with cairo_text_path; cairo_fill. This will let + * us look more closely at the remaining positioning problems. (In + * particular, I want to make sure we're rounding as well as + * possible). + * + * 2007-02-21 + * + * Seems like all the "bugs" have been fixed and all remaining is + * missing support for subpixel glyph positioning.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.
