For linearized files, this appears after the + linearization parameter dictionary. For non-linearized files, it + appears right after the PDF header and non-ASCII comment. + + * Make it possible to write the same QPDF object with two + different QPDFWriter objects that have both called + setLinearization(true) by making private method + QPDF::calculateLinearizationData() properly initialize its state. + + * Bug fix: Writing after calling QPDFWriter::setOutputMemory() + would cause a segmentation fault because of an internal field not + being initialized, rendering that method useless. This has been + corrected. + +2012-08-11 Jay Berkenbilt + + * 3.0.1: release + + * Bug fix: let EOF terminate a literal token as well as + whitespace or comments. + +2012-07-31 Jay Berkenbilt + + * 3.0.0: release + +2012-07-29 Jay Berkenbilt + + * 3.0.rc1: release + +2012-07-25 Jay Berkenbilt + + * From Tobias: add QPDFObjectHandle::replaceStreamData that takes + a std::string analogous to the QPDFObjectHandle::newStream that + takes a string that was added earlier. + +2012-07-21 Jay Berkenbilt + + * Change configure to have image comparison tests disabled by + default. Update README and README.maintainer with information + about running them. + + * Add --pages command-line option to qpdf to enable page-based + merging and splitting. + + * Add new method QPDFObjectHandle::replaceDict to replace a + stream's dictionary. Use with caution; see comments in + QPDFObjectHandle.hh. + + * Add new method QPDFObjectHandle::parse for creation of + QPDFObjectHandle objects from string representations of the + objects. Thanks to Tobias Hoffmann for the idea. + +2012-07-15 Jay Berkenbilt + + * add new QPDF::isEncrypted method that returns some additional + information beyond other versions. + + * libqpdf/QPDFWriter.cc: fix copyEncryptionParameters to fix the + minimum PDF version based on other file's encryption needs. This + is a fix to code added on 2012-07-14 and did not impact previously + released code. + + * libqpdf/QPDFWriter.cc (copyEncryptionParameters): Bug fix: qpdf + was not preserving whether or not AES encryption was being used + when copying encryption parameters. The file would still have + been properly encrypted, but a file that started off encrypted + with AES could have become encrypted with RC4. + +2012-07-14 Jay Berkenbilt + + * QPDFWriter: add public copyEncryptionParameters to allow copying + encryption parameters from another file. + + * QPDFWriter: detect if the user has inserted an indirect object + from another QPDF object and throw an exception directing the user + to copyForeignObject. + +2012-07-11 Jay Berkenbilt + + * Added new APIs to copy objects from one QPDF to another. This + includes letting QPDF::addPage() (and QPDF::addPageAt()) accept a + page object from another QPDF and adding + QPDF::copyForeignObject(). See QPDF.hh for details. + + * Add method QPDFObjectHandle::getOwningQPDF() to return the QPDF + object associated with an indirect QPDFObjectHandle. + + * Add convenience methods to QPDFObjectHandle: assertIndirect(), + isPageObject(), isPagesObject() + + * Cache when QPDF::pushInheritedAttributesToPage() has been called + to avoid traversing the pages trees multiple times. This state is + cleared by QPDF::updateAllPagesCache() and ignored by + QPDF::flattenPagesTree(). + +2012-07-08 Jay Berkenbilt + + * Add QPDFObjectHandle::newReserved to create a reserved object + and QPDF::replaceReserved to replace it with a real object. + QPDFObjectHandle::newReserved reserves an object ID in a QPDF + object and ensures that any references to it remain unresolved. + When QPDF::replaceReserved is later called, previous references to + the reserved object will properly resolve to the replaced object. + +2012-07-07 Jay Berkenbilt + + * NOTE: BREAKING API CHANGE. Remove previously required length + parameter from the version QPDFObjectHandle::replaceStreamData + that uses a stream data provider. Prior to qpdf 3.0.0, you had to + compute the stream length in advance so that qpdf could internally + verify that the stream data had the same length every time the + provider was invoked. Now this requirement is enforced a + different way, and the length parameter is no longer required. + Note that I take API-breaking changes very seriously and only did + it in this case since the lack of need to know length in advance + could significantly simplify people's code. If you were + previously going to a lot of trouble to compute the length of the + new stream data in advance, you now no longer have to do that. + You can just drop the length parameter and remove any code that + was previously computing the length. Thanks to Tobias Hoffmann + for pointing out how annoying the original interface was. + +2012-07-05 Jay Berkenbilt + + * Add QPDFWriter methods to write to an already open stdio FILE*. + Implementation and idea area based on contributions from Tobias + Hoffmann. + +2012-07-04 Jay Berkenbilt + + * Accept changes from Tobias Hoffmann: add public method + QPDF::pushInheritedAttributesToPage including warnings for + non-inherited keys that may be discarded from /Pages by + non-conformant PDF files when the /Pages tree is flattened. + +2012-06-27 Jay Berkenbilt + + * Add Pl_Concatenate pipeline for stream concatenation also + implemented by Tobias Hoffmann. Also added test code + (libtests/concatenate.cc). + + * Add new methods implemented by Tobias Hoffmann: + QPDFObjectHandle::newReal(double) and + QPDFObjectHandle::newStream(QPDF*, std::string const&). + +2012-06-26 Jay Berkenbilt + + * Minor changes so that support for PDF files larger than 4GB + works well with 32-bit and 64-bit Linux and also with 32-bit and + 64-bit Windows with both MSVC and mingw. + + * Rework internal methods for doing recovery of the cross + reference tables for much greater efficiency both in terms of time + and memory usage. + +2012-06-24 Jay Berkenbilt + + * Support PDF files larger than 4 GB. This involved many changes + to the ABI to increase the size of integer types used in various + places as well as increasing the amount of padding used when + creating linearized files. Automated tests for large files are + disabled by default. Run ./configure --help for information on + enabling them. Running the tests requires 11 GB of free disk + space and takes several minutes. + +2012-06-22 Jay Berkenbilt + + * examples/pdf-create.cc: Provide an example of creating a PDF + from scratch. This simple PDF has a single page with some text + and an image. + + * Add empty QPDFObjectHandle factories for array and dictionary. + With PDF-from-scratch capability, it is useful to be able to + create empty arrays and dictionaries and add keys to them. + Updated pdf_from_scratch.cc to use these interfaces. + +2012-06-21 Jay Berkenbilt + + * Add QPDF::emptyPDF() to create an empty QPDF object suitable for + adding pages and other objects to. pdf_from_scratch.cc is test + code that exercises it. + + * make/libtool.mk: Place user-specified CPPFLAGS and LDFLAGS later + in the compilation so that if a user installs things in a + non-standard place that they have to tell the build about, earlier + versions of qpdf installed there won't break the build. Thanks to + Macports for reporting this. (Fixes bug 3468860.) + + * Instead of using off_t in the public APIs, use qpdf_offset_t + instead. This is defined as long long in qpdf/Types.h. If your + system doesn't support long long, you can redefine it. + + * Add pkg-config files + + * QPDFObjectHandle: add shallowCopy() method + + * QPDF: add new APIs for adding and removing pages. This includes + addPage(), addPageAt(), and removePage(). Also a method + updateAllPagesCache() is now available to force update of the + internal pages cache if you should modify the pages structure + manually. + + * QPDF: new processFile method that takes an open FILE* + instead of a filename. + +2012-06-20 Jay Berkenbilt + + * Add new array mutation routines to QPDFObjectHandle. + Implemented by Tobias Hoffmann. + + * Rework APIs that use size_t, off_t, and primative integer types + so that size_t is used for sizes of memory and off_t is used for + file offsets. Also set _FILE_OFFSET_BITS so that large files can + be supported on 32-bit UNIX/Linux platforms. The code assumes in + places that sizeof(off_t) >= sizeof(size_t). This resulted in + non-compatible ABI changes and hopefully clears the way for QPDF + to work with files that are larger than 4 GiB in size. + + * Add support for versioned symbols on ELF platforms. + + * Various fixes for gcc 4.7 + +2011-04-06 Jay Berkenbilt + + * Fix PCRE to stop using deprecated (and now dropped) interfaces. + +2011-12-28 Jay Berkenbilt + + * 2.3.1: release + + * include if available to support MSVC 2010 + + * Since PCRE is not necessarily thread safe, don't declare any + PCRE objects to be static. + + * Disregard stderr output from ghostscript when using it to + compare images in the test suite; see comments in qpdf.test for + details. + + * Fixed a few documentation errors. + +2011-08-11 Jay Berkenbilt + + * 2.3.0: release + + * include/qpdf/qpdf-c.h ("C"): add new methods + qpdf_init_write_memory, qpdf_get_buffer_length, and + qpdf_get_buffer to support writing to memory from the C API. + + * include/qpdf/qpdf-c.h ("C"): add new methods qpdf_get_info_key + and qpdf_set_info_key for manipulating text fields of the /Info + dictionary. + +2011-08-10 Jay Berkenbilt + + * libqpdf/QPDFWriter.cc (copyEncryptionParameters): preserve + whether metadata is encryption. This fixes part of bug 3173659: + the password becomes invalid if qpdf copies an encrypted file with + cleartext-metadata. + + * include/qpdf/QPDFWriter.hh: add a new constructor that takes + only a QPDF reference and leaves specification of output for + later. Add methods setOutputFilename() to set the output to a + filename or stdout, and setOutputMemory() to indicate that output + should go to a memory buffer. Add method getBuffer() to retrieve + the buffer used if output was saved to a memory buffer. + + * include/qpdf/QPDF.hh: add methods replaceObject() and + swapObjects() to allow replacement of an object and swapping of + two objects by object ID. + + * include/qpdf/QPDFObjectHandle.hh: add new methods getDictAsMap() + and getArrayAsVector() for returning the elements of a dictionary + or an array as a map or vector. + +2011-06-25 Jay Berkenbilt + + * 2.2.4: release + +2011-06-23 Jay Berkenbilt + + * make/libtool.mk (install): Do not strip executables and shared + libraries during installation.

While + this is not permitted by the specification, there are PDF files + that do this, and other readers can read them. + + * libqpdf/Pl_QPDFTokenizer.cc (processChar): When an inline image + is detected, suspend normalization only up to the end of the + inline image rather than for the remainder of the content stream. + (Fixes qpdf-Bugs 3152169.) + +2011-01-31 Jay Berkenbilt + + * libqpdf/QPDF.cc (readObjectAtOffset): use -1 rather than 0 when + reading an object at a given to indicate that no object number is + expected. This allows xref recovery to proceed even if a file + uses the invalid object number 0 as a regular object. + + * libqpdf/QPDF_linearization.cc (isLinearized): use -1 rather than + 0 as a sentintel for not having found the first object in the + file. Since -1 can never match the regular expression, this + prevents an infinite loop when checking a file that starts with + (erroneous) 0 0 obj. (Fixes qpdf-Bugs-3159950.) + +2010-10-04 Jay Berkenbilt + + * 2.2.2: release + + * include/qpdf/qpdf-c.h: Add qpdf_read_memory to C API to call + QPDF::processMemoryFile. + +2010-10-01 Jay Berkenbilt + + * 2.2.1: release + + * include/qpdf/QPDF.hh: Add setOutputStreams method to allow + redirection of library-generated output/error to alternative + streams. + + * include/qpdf/QPDF.hh: Add processMemoryFile method for + processing a PDF file from a memory buffer instead of a file. + +2010-09-24 Jay Berkenbilt + + * libqpdf/QPDF.cc: change private "file" method to be a + PointerHolder to prepare qpdf for being able to work + with PDF files loaded into memory in addition to working with + files on disk. + + * include/qpdf/PointerHolder.hh: add operator* and operator-> + methods so that PointerHolder objects can be used like pointers. + This is consistent with the smart pointer objects in the next + revision of C++. + +2010-09-05 Jay Berkenbilt + + * libqpdf/QPDF.cc (readObjectInternal): Recognize empty objects + and treat them as null. + + * libqpdf/QPDF_Stream.cc (filterable): Handle inline image filter + abbreviations as stream filter abbreviations. Although this is + not technically allowed by the PDF specification, table H.1 in the + pre-ISO spec indicates that Adobe's readers accept them. Thanks + to Jian Ma for bringing this to my + attention. + +2010-08-14 Jay Berkenbilt + + * 2.2.0: release + + * Rename README.windows to README-windows.txt and convert its line + endings to Windows-style line endings. Also mention Jian Ma's VC6 + port in the manual and README-windows.txt. + +2010-08-09 Jay Berkenbilt + + * Add QPDFObjectHandle::getRawStreamData to return raw + (unfiltered) stream data. + +2010-08-08 Jay Berkenbilt + + * 2.2.rc1: release + +2010-08-05 Jay Berkenbilt + + * Add QPDFObjectHandle::addPageContents, a convenience routine for + appending or prepending new streams to a page's content streams. + The "pdf-double-page-size" example illustrates its use. + + * Add new methods to QPDFObjectHandle: replaceStreamData and + newStream.

(Fixes + qpdf-Bugs-2991412.) + +2010-04-18 Jay Berkenbilt + + * 2.1.4: release + + * libqpdf/QPDFWriter.cc (writeLinearized): the padding calculation + fix in 2.1.2 was applied in only one place but it was needed in + two places since there are actually two cross reference streams in + a linearized file. The new padding calculation is now used for + both streams. Hopefully this should put an end to linearization + padding problems. (Fixes qpdf-Bugs-2979219.) + +2010-04-10 Jay Berkenbilt + + * qpdf/qpdf.cc (main): Since qpdf --check only checks syntax and + stream encoding without doing any semantic checks, make the output + clearer when no errors around found.

This way, warnings may be + inspected in more detail. + + * Include information about the last object read in most error + messages.

However, qpdf does not use automake, so not all of that file +applies. + +Basic Installation +================== + +Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + You can also define the variable DESTDIR when you run make install +to install the package in a separate subdirectory. This is useful for +packaging. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options.

It is provided "as is" without express or implied +warranty. + + +Prerequisites +============= + +QPDF depends on external libraries "zlib" and "pcre". These are part +of virtually all Linux distributions and are readily available; +download information appears in the documentation. For Windows, you +can download pre-built binary versions of those libraries for some +compilers; see README-windows.txt for additional details. + +QPDF requires a C++ compiler that works with STL. Your compiler must +also support "long long". Almost all modern compilers do. If you are +trying to port qpdf to a compiler that doesn't support long long, you +could change all occurrences of "long long" to "long" in the source +code, noting that this would break binary compatibility with other +builds of qpdf. Doing so would certainly prevent qpdf from working +with files larger than 2 GB, but remaining functionality would most +likely work fine. If you built qpdf this way and it passed its test +suite with large file support disabled, you could be confident that +you had an otherwise working qpdf. + + +Licensing terms of embedded software +==================================== + +QPDF makes use of zlib and pcre for its functionality. These packages +can be downloaded separately from their own download locations, or +they can be downloaded in the external-libs area of the qpdf download +site. + +The Rijndael encryption implementation used as the basis for AES +encryption and decryption support comes from Philip J. Erdelsky's +public domain implementation. The files libqpdf/rijndael.cc and +libqpdf/qpdf/rijndael.h remain in the public domain. They were +obtained from + + http://www.efgh.com/software/rijndael.htm + http://www.efgh.com/software/rijndael.txt + + +Building on UNIX/Linux +====================== + +For UNIX and UNIX-like systems, you can usually get by with just + +./configure +make +make install + +Packagers may set DESTDIR, in which case make install will install +inside of DESTDIR, as is customary with many packages. For more +detailed general information, see the "INSTALL" file in this +directory. If you are already accustomed to building and installing +software that uses autoconf, there's nothing new for you in the +INSTALL file. + + +Building on Windows +=================== + +QPDF is known to build and pass its test suite with mingw (latest +version tested: gcc 4.6.2), mingw64 (latest version tested: 4.7.0) and +Microsoft Visual C++ 2010, both 32-bit and 64-bit versions. MSYS plus +ActiveState Perl is required to build as well in order to get make +and other related tools. See README-windows.txt for details on how to +build under Windows, see README-windows.txt. + + +Additional Notes on Build +========================= + +QPDF's build system, inspired by abuild (http://www.abuild.org), can +optionally use its own built-in rules rather than using libtool and +obeying the compiler specified with configure. This can be enabled by +passing --with-buildrules=buildrules where buildrules corresponds to +one of the .mk files (other than rules.mk) in the make directory. +This should never be necessary on a UNIX system, but may be necessary +on a Windows system. See README-windows.txt for details. There is a +gcc-linux.mk file enable "gcc-linux" build rules, but it is intended +to help test the build system; Linux users should build with the +"libtools" rules, which are enabled by default. + +The QPDF package provides some executables and a software library. A +user's manual can be found in the "doc" directory. The docbook +sources to the user's manual can be found in the "manual" directory. + +The software library is just libqpdf, and all the header files are in +the qpdf subdirectory. If you link statically with -lqpdf, then you +will also need to link with -lpcre and -lz. The shared qpdf library +is linked with -lpcre and -lz, and none of qpdf's public header files +directly include files from pcre or libz, so in many cases, qpdf's +development files are self contained. + +To learn about using the library, please read comments in the header +files in include/qpdf, especially QPDF.hh, QPDFObjectHandle.hh, and +QPDFWriter.hh. You can also study the code of qpdf/qpdf.cc, which +exercises most of the public interface. There are additional example +programs in the examples directory. Reading all the source files in +the qpdf directory (including the qpdf command-line tool and some test +drivers) along with the code in the examples directory will give you a +complete picture of every aspect of the public interface. + + +Additional Notes on Test Suite +============================== + +By default, slow tests are disabled. Slow tests include image +comparison tests and large file tests. Image comparison tests can be +enabled by passing --enable-test-compare-images to ./configure. This +was on by default in qpdf versions prior to 3.0, but is now off by +default. Large file tests can be enabled by passing +--with-large-file-test-path=path to ./configure or by setting the +QPDF_LARGE_FILE_TEST_PATH environment variable. Run ./configure +--help for additional options. The test suite provides nearly full +coverage even without these tests. Unless you are making deep changes +to the library that would impact the contents of the generated PDF +files or testing this on a new platform for the first time, there is +no real reason to run these tests. If you're just running the test +suite to make sure that qpdf works for your build, the default tests +are adequate. The configure rules for these tests do nothing other +than setting variables in autoconf.mk, so you can feel free to turn +these on and off directly in autoconf.mk rather than rerunning +configure. + +If you are packaging qpdf for a distribution and preparing a build +that is run by an autobuilder, you may want to add the +--enable-show-failed-test-output to configure options. This way, if +the test suite fails, test failure detail will be included in the +build output. Otherwise, you will have to have access to the +qtest.log file from the build to view test failures. The debian +packages for qpdf enable this option, for example. diff --git a/README-what-to-download.txt b/README-what-to-download.txt new file mode 100644 index 0000000..de04557 --- /dev/null +++ b/README-what-to-download.txt @@ -0,0 +1,52 @@ +To build from source for Linux or other UNIX/UNIX-like systems, it is +generally sufficient to download just the source qpdf-.tar.gz +file. + +For Windows, there are several additional files that you might want to +download. + + * qpdf--bin-mingw32.zip + + If you just want to use the qpdf command line program or use the + qpdf DLL's C-language interface, you can download this file.

From the msys shell, run + +mingw-get install msys-unzip msys-zip mingw32-make + +Then replace perl and make with the appropriate versions: + +mv /bin/perl.exe /bin/msys-perl.exe +mv /bin/make.exe /bin/msys-make.exe +mv /mingw/bin/mingw32-make.exe /mingw/bin/make.exe + +Make sure perl --version shows ActiveState perl. + +To install MinGW-w64, first install msys and mingw32 as above. + +From MinGW-w64 download page, go to "Toolchains targeting +Win64/Automated Builds" and find the latest mingw-w64 that runs under +i686-mingw. It will be called something like +mingw-w64-bin_i686-mingw_yyyymmdd.zip. The compiler binaries are +32-bit, which (of course) runs on 64-bit Windows. Extract this under +C:\MinGW-w64, and add C:\MinGW-w64\bin and C:\MinGW-w64\lib\mingw to +the path. + +As of this writing, the image comparison tests confuse ghostscript in +cygwin, but there's a chance they might work at some point. If you +want to run them, you need ghostscript and tiff utils as well, and you +will need to add --enable-test-compare-images from the configure +statements given below. + +Jian Ma has generously provided a port of QPDF +that works with Microsoft VC6. Several changes are required, but they +are well documented in his port. You can find the VC6 port in the +contrib area of the qpdf download area. It may not always be +up-to-date with the latest official qpdf release. + + +External Libraries +================== + +In order to build qpdf, you must have copies of zlib and pcre. The +easy way to get them is to download them from the qpdf download area. +There are packages called external-libs-bin.zip and +external-libs-src.zip. If you are building with MSVC 2010 or MINGW, +you can just extract the qpdf-external-libs-bin.zip zip file into the +top-level qpdf source tree. Note that you need the 2012-06-20 version +(at least) to build qpdf 3.0 or greater since this includes 64-bit +libraries. It will create a directory called external-libs which +contains header files and precompiled libraries. Passing +--enable-external-libs to ./configure (which is done automatically if +you follow the instructions below) is sufficient to find them. + +You can also obtain pcre and zlib directly on your own and install +them. If you are using mingw, you can just set CPPFLAGS, LDFLAGS, and +LIBS when you run ./configure so that it can find the header files and +libraries. If you are building with msvc and you want to do this, it +probably won't work because ./configure doesn't know how to interpret +LDFLAGS and LIBS properly for MSVC (though qpdf's own build system +does). In this case, you can probably get away with cheating by +passing --enable-external-libs to ./configure and then just editing +CPPFLAGS, LDFLAGS, LIBS in the generated autoconf.mk file. Note that +you should use UNIX-like syntax (-I, -L, -l) even though this is not +what cl takes on the command line. qpdf's build rules will fix it. + +You can also download qpdf-external-libs-src.zip and follow the +instructions in the README.txt there for how to build external libs. + + +Building with MinGW +=================== + +QPDF is known to build and pass its test suite with mingw (latest +version tested: gcc 4.6.2), mingw64 (latest version tested: 4.7.0) and +Microsoft Visual C++ 2010, both 32-bit and 64-bit versions. MSYS plus +ActiveState Perl is required to build as well in order to get make +and other related tools. While it is possible that Cygwin could be +used to build native Windows versions of qpdf, this configuration has +not been tested recently. + +From your MSYS prompt, run + + ./config-mingw32 + +or + + ./config-mingw64 + +and then + + make + +Note that ./config-mingw32 and ./configure-mingw64 just run +./configure with specific arguments, so you can look at it, make +adjustments, and manually run configure instead. Note also that +config-mingw32 appends definition of _FILE_OFFSET_BITS=64 to +qpdf-config.h since, as of the qpdf 3.0 release, the current versions +of the autoconf tools did not correctly detect that mingw requires +this to get large file support. This workaround is only required for +mingw32. The 64-bit version of mingw works "out of the box" with +large file support, as do both the 32-bit and 64-bit versions of MSVC. + +Add the absolute path to the libqpdf/build directory to your PATH. +Make sure you can run the qpdf command by typing qpdf/build/qpdf and +making sure you get a help message rather than an error loading the +DLL or no output at all. Run the test suite by typing + + make check + +If all goes well, you should get a passing test suite. + +To create an installation directory, run make install. This will +create install-mingw/qpdf-VERSION and populate it. The binary +download of qpdf for Windows with mingw is created from this +directory. + +You can also take a look at make_windows_releases for reference. This +is how the distributed Windows executables are created. + + +Building with MSVC 2010 +======================= + +These instructions would likely work with newer version of MSVC or +with full version of MSVC. They may also work with .NET 2005. They +have only been tested with Visual C++ 2010. Earlier version of qpdf +were built with MSVC 2008 Express. + +You should first set up your environment to be able to run MSVC from +the command line. There is usually a batch file included with MSVC +that does this. Make sure that you start a command line environment +configured for whichever of 32-bit or 64-bit output that you intend to +build for. + +From that cmd prompt, you can start your msys shell by just running +manually whatever command is associated with your msys shell icon. + +Configure as follows: + + ./config-msvc 32 + +or + + ./config-msvc 64 + +Note that you must pass the 32/64 option that matches your command +line setup. The scripts do not presently figure this out. If you +used the wrong argument, it would probably just build the size you +have in your environment and then install the results in the wrong +place. + +Once configured, run + + make + +Note that ./config-msvc just runs ./configure with specific arguments, +so you can look at it, make adjustments, and manually run configure +instead. + +NOTE: automated dependencies are not generated with the msvc build. +If you're planning on making modifications, you should probably work +with mingw. If there is a need, I can add dependency information to +the msvc build, but since I only use it for generating release +versions, I haven't bothered. + +Once built, add the full path to the libqpdf/build directory to your +path and run + + make check + +to run the test suite. + +If you are building with MSVC and want to debug a crash in MSVC's +debugger, first start an instance of Visual C++. Then run qpdf. When +the abort/retry/ignore dialog pops up, first attach the process from +within visual C++, and then click Retry in qpdf. + +A release version of qpdf is built by default. If you want to link +against debugging libraries, you will have to change /MD to /MDd in +make/msvc.mk. Note that you must redistribute the Microsoft runtime +DLLs. Linking with static runtime (/MT) won't work; see "Static +Runtime" below for details. + + +Runtime DLLs +============ + +Both build methods create executables and DLLs that are dependent on +the compiler's runtime DLLs. When you run make install, the +installation process will automatically detect the DLLs and copy them +into the installation bin directory. Look at the copy_dlls script for +details on how this is accomplished. + +Redistribution of the runtime DLL is unavoidable as of this writing; +see "Static Runtime" below for details. + + +Static Runtime +============== + +Building the DLL and executables with static runtime does not work +with either Visual C++ .NET 2008 (a.k.a. vc9) using /MT or with mingw +(at least as of 4.4.0) using -static-libgcc. The reason is that, in +both cases, there is static data involved with exception handling, and +when the runtime is linked in statically, exceptions cannot be thrown +across the DLL to EXE boundary. Since qpdf uses exception handling +extensively for error handling, we have no choice but to redistribute +the C++ runtime DLLs. Maybe this will be addressed in a future +version of the compilers. This has not been retested with the +toolchain versions used to create qpdf 3.0 distributions. diff --git a/README.maintainer b/README.maintainer new file mode 100644 index 0000000..b150eeb --- /dev/null +++ b/README.maintainer @@ -0,0 +1,143 @@ +Release Reminders +================= + + * When making a release, always remember to run large file tests and + image comparison tests (--enable-test-compare-images + --with-large-file-test-path=/path).

PDF Reference 1.7 section 3.10, "File + Specifications", discusses this. Once we can definitely recognize + all embedded files in a document, we can update the encryption + code to handle it properly. In QPDF_encryption.cc, search for + cf_file. Remove exception thrown if cf_file is different from + cf_stream, and write code in the stream decryption section to use + cf_file instead of cf_stream. In general, add interfaces to get + the list of embedded files and to extract them. To handle general + embedded files associated with the whole document, follow root -> + /Names -> /EmbeddedFiles -> /Names to get to the file specification + dictionaries. Then, in each file specification dictionary, follow + /EF -> /F to the actual stream. There may be other places file + specification dictionaries may appear, and there are also /RF keys + with related files, so reread section 3.10 carefully. + + * The description of Crypt filters is unclear with respect to how to + use them to override /StmF for specific streams. I'm not sure + whether qpdf will do the right thing for any specific individual + streams that might have crypt filters. The specification seems to + imply that only embedded file streams and metadata streams can have + crypt filters, and there are already special cases in the code to + handle those. Most likely, it won't be a problem, but someday + someone may find a file that qpdf doesn't work on because of crypt + filters. There is an example in the spec of using a crypt filter + on a metadata stream. + + For now, we notice /Crypt filters and decode parameters consistent + with the example in the PDF specification, and the right thing + happens for metadata filters that happen to be uncompressed or + otherwise compressed in a way we can filter. This should handle + all normal cases, but it's more or less just a guess since I don't + have any test files that actually use stream-specific crypt filters + in them. + + * The second xref stream for linearized files has to be padded only + because we need file_size as computed in pass 1 to be accurate. If + we were not allowing writing to a pipe, we could seek back to the + beginning and fill in the value of /L in the linearization + dictionary as an optimization to alleviate the need for this + padding. Doing so would require us to pad the /L value + individually and also to save the file descriptor and determine + whether it's seekable. This is probably not worth bothering with. + + * The whole xref handling code in the QPDF object allows the same + object with more than one generation to coexist, but a lot of logic + assumes this isn't the case. Anything that creates mappings only + with the object number and not the generation is this way, + including most of the interaction between QPDFWriter and QPDF. If + we wanted to allow the same object with more than one generation to + coexist, which I'm not sure is allowed, we could fix this by + changing xref_table. Alternatively, we could detect and disallow + that case. In fact, it appears that Adobe reader and other PDF + viewing software silently ignores objects of this type, so this is + probably not a big deal. + + * Pl_PNGFilter is only partially implemented. If we ever decoded + images, we'd have to finish implementing it along with the other + filter decode parameters and types. For just handling xref + streams, there's really no need as it wouldn't make sense to use + any kind of predictor other than 12 (PNG UP filter). + + * If we ever want to have check mode check the integrity of the free + list, this can be done by looking at the code from prior to the + object stream support of 4/5/2008. It's in an if (0) block and + there's a comment about it. There's also something about it in + qpdf.test -- search for "free table".

The C API is primarily useful for doing basic + * transformations on PDF files similar to what you might do with + * the qpdf command-line tool. + * + * These functions store their state in a qpdf_data object. + * Individual instances of qpdf_data are not thread-safe: although + * you may access different qpdf_data objects from different + * threads, you may not access one qpdf_data simultaneously from + * multiple threads. + * + * All dynamic memory, except for that of the qpdf_data object + * itself, is managed by the library. You must create a qpdf_data + * object using qpdf_init and free it using qpdf_cleanup. + * + * Many functions return char*. In all cases, the char* values + * returned are pointers to data inside the qpdf_data object. As + * such, they are always freed by qpdf_cleanup. In most cases, + * strings returned by functions here may be invalidated by + * subsequent function calls, sometimes even to different + * functions. If you want a string to last past the next qpdf + * call or after a call to qpdf_cleanup, you should make a copy of + * it. + * + * Many functions defined here merely set parameters and therefore + * never return error conditions. Functions that may cause PDF + * files to be read or written may return error conditions. Such + * functions return an error code. If there were no errors or + * warnings, they return QPDF_SUCCESS. If there were warnings, + * the return value has the QPDF_WARNINGS bit set. If there + * errors, the QPDF_ERRORS bit is set. In other words, if there + * are both warnings and errors, then the return status will be + * QPDF_WARNINGS | QPDF_ERRORS. You may also call the + * qpdf_more_warnings and qpdf_more_errors functions to test + * whether there are unseen warning or error conditions. By + * default, warnings are written to stderr when detected, but this + * behavior can be suppressed. In all cases, errors and warnings + * may be retrieved by calling qpdf_next_warning and + * qpdf_next_error. All exceptions thrown by the C++ interface + * are caught and converted into error messages by the C + * interface. + * + * Most functions defined here have obvious counterparts that are + * methods to either QPDF or QPDFWriter. Please see comments in + * QPDF.hh and QPDFWriter.hh for details on their use. In order + * to avoid duplication of information, comments here focus + * primarily on differences between the C and C++ API. + */ + +#include +#include +#include +#include + +#ifdef __cplusplus +extern "C" { +#endif + + typedef struct _qpdf_data* qpdf_data; + typedef struct _qpdf_error* qpdf_error; + + /* Many functions return an integer error code.

QPDF's website is located at http://qpdf.sourceforge.net/. + QPDF's source code is hosted on github at https://github.com/qpdf/qpdf. + + + QPDF has been released under the terms of Version + 2.0 of the Artistic License, a copy of which appears in the + file Artistic-2.0 in the source distribution. + + + QPDF was originally created in 2001 and modified periodically + between 2001 and 2005 during my employment at Apex CoVantage. Upon my + departure from Apex, the company graciously allowed me to take + ownership of the software and continue maintaining as an open + source project, a decision for which I am very grateful. I have + made considerable enhancements to it since that time. I feel + fortunate to have worked for people who would make such a decision. + This work would not have been possible without their support. + + + + What is QPDF? + + QPDF is a program that does structural, content-preserving + transformations on PDF files. It could have been called something + like pdf-to-pdf. It also provides many useful + capabilities to developers of PDF-producing software or for people + who just want to look at the innards of a PDF file to learn more + about how they work. + + + With QPDF, it is possible to copy objects from one PDF file into + another and to manipulate the list of pages in a PDF file. This + makes it possible to merge and split PDF files. The QPDF library + also makes it possible for you to create PDF files from scratch. + In this mode, you are responsible for supplying all the contents of + the file, while the QPDF library takes care off all the syntactical + representation of the objects, creation of cross references tables + and, if you use them, object streams, encryption, linearization, + and other syntactic details. You are still responsible for + generating PDF content on your own. + + + QPDF has been designed with very few external dependencies, and it + is intentionally very lightweight. QPDF is + not a PDF content creation library, a PDF + viewer, or a program capable of converting PDF into other formats. + In particular, QPDF knows nothing about the semantics of PDF + content streams. If you are looking for something that can do + that, you should look elsewhere. However, once you have a valid + PDF file, QPDF can be used to transform that file in ways perhaps + your original PDF creation can't handle. For example, many + programs generate simple PDF files but can't password-protect them, + web-optimize them, or perform other transformations of that type. + + + + Building and Installing QPDF + + This chapter describes how to build and install qpdf. Please see + also the README and + INSTALL files in the source distribution. + + + System Requirements + + The qpdf package has relatively few external dependencies. In + order to build qpdf, the following packages are required: + + + + zlib: http://www.zlib.net/ + + + + + pcre: http://www.pcre.org/ + + + + + gnu make 3.81 or newer: http://www.gnu.org/software/make + + + + + perl version 5.8 or newer: + http://www.perl.org/; + required for fix-qdf and the test suite. + + + + + GNU diffutils (any version): http://www.gnu.org/software/diffutils/ + is required to run the test suite. Note that this is the + version of diff present on virtually all GNU/Linux systems. + This is required because the test suite uses diff + -u. + + + + + A C++ compiler that works well with STL and has the long + long type. Most modern C++ compilers should fit the + bill fine. QPDF is tested with gcc and Microsoft Visual C++. + + + + + + Part of qpdf's test suite does comparisons of the contents PDF + files by converting them images and comparing the images. The + image comparison tests are disabled by default. Those tests are + not required for determining correctness of a qpdf build if you + have not modified the code since the test suite also contains + expected output files that are compared literally. The image + comparison tests provide an extra check to make sure that any + content transformations don't break the rendering of pages. + Transformations that affect the content streams themselves are off + by default and are only provided to help developers look into the + contents of PDF files. If you are making deep changes to the + library that cause changes in the contents of the files that qpdf + generates, then you should enable the image comparison tests. + Enable them by running configure with the + flag. If you enable + this, the following additional requirements are required by the + test suite. Note that in no case are these items required to use + qpdf. + + + + libtiff: http://www.remotesensing.org/libtiff/ + + + + + GhostScript version 8.60 or newer: http://www.ghostscript.com + + + + If you do not enable this, then you do not need to have tiff and + ghostscript. + + + If Adobe Reader is installed as acroread, some + additional test cases will be enabled. These test cases simply + verify that Adobe Reader can open the files that qpdf creates. + They require version 8.0 or newer to pass. However, in order to + avoid having qpdf depend on non-free (as in liberty) software, the + test suite will still pass without Adobe reader, and the test + suite still exercises the full functionality of the software. + + + Pre-built documentation is distributed with qpdf, so you should + generally not need to rebuild the documentation. In order to + build the documentation from its docbook sources, you need the + docbook XML style sheets (http://downloads.sourceforge.net/docbook/). + To build the PDF version of the documentation, you need Apache fop + (http://xml.apache.org/fop/) + version 0.94 or higher. + + + + Build Instructions + + Building qpdf on UNIX is generally just a matter of running + + ./configure +make + + You can also run make check to run the test + suite and make install to install. Please run + ./configure --help for options on what can be + configured. You can also set the value of + DESTDIR during installation to install to a + temporary location, as is common with many open source packages. + Please see also the README and + INSTALL files in the source distribution. + + + Building on Windows is a little bit more complicated. For + details, please see README-windows.txt in the + source distribution. You can also download a binary distribution + for Windows. There is a port of qpdf to Visual C++ version 6 in + the contrib area generously contributed by + Jian Ma. This is also discussed in more detail in + README-windows.txt. + + + There are some other things you can do with the build. Although + qpdf uses autoconf, it does not use + automake but instead uses a + hand-crafted non-recursive Makefile that requires gnu make. If + you're really interested, please read the comments in the + top-level Makefile. + + + + + Running QPDF + + This chapter describes how to run the qpdf program from the command + line. + + + Basic Invocation + + When running qpdf, the basic invocation is as follows: + + qpdf + + This converts PDF file to PDF file + . The output file is functionally + identical to the input file but may have been structurally + reorganized. Also, orphaned objects will be removed from the + file. Many transformations are available as controlled by the + options below. In place of , the + parameter may be specified. This causes + qpdf to use a dummy input file that contains zero pages. The only + normal use case for using would be if you + were going to add pages from another source, as discussed in . + + + does not have to be seekable, even + when generating linearized files. Specifying + “” as + means to write to standard output. However, you can't specify the + same file as both the input and the output because qpdf reads data + from the input file as it writes to the output file. + + + Most options require an output file, but some testing or + inspection commands do not. These are specifically noted. + + + + Basic Options + + The following options are the most common ones and perform + commonly needed transformations. + + + + + + Specifies a password for accessing encrypted files. + + + + + + + + Causes generation of a linearized (web-optimized) output file. + + + + + + + + Encrypt the file using the same encryption parameters, + including user and owner password, as the specified file. Use + to specify a password + if one is needed to open this file. Note that copying the + encryption parameters from a file also copies the first half + of /ID from the file since this is part of + the encryption parameters. + + + + + + + + If the file specified with + requires a password, specify the password using this option. + Note that only one of the user or owner password is required. + Both passwords will be preserved since QPDF does not + distinguish between the two passwords. It is possible to + preserve encryption parameters, including the owner password, + from a file even if you don't know the file's owner password. + + + + + + + + Causes generation an encrypted output file. Please see for details on how to + specify encryption parameters. + + + + + + + + Removes any encryption on the file. A password must be + supplied if the file is password protected. + + + + + + + + Select specific pages from one or more input files. See for details on how to do page + selection (splitting and merging). + + + + + + + Password-protected files may be opened by specifying a password. + By default, qpdf will preserve any encryption data associated with + a file. If is specified, qpdf will + attempt to remove any encryption information. If + is specified, qpdf will replace the + document's encryption parameters with whatever is specified. + + + Note that qpdf does not obey encryption restrictions already + imposed on the file. Doing so would be meaningless since qpdf can + be used to remove encryption from the file entirely. This + functionality is not intended to be used for bypassing copyright + restrictions or other restrictions placed on files by their + producers. + + + In all cases where qpdf allows specification of a password, care + must be taken if the password contains characters that fall + outside of the 7-bit US-ASCII character range to ensure that the + exact correct byte sequence is provided. It is possible that a + future version of qpdf may handle this more gracefully. For + example, if a password was encrypted using a password that was + encoded in ISO-8859-1 and your terminal is configured to use + UTF-8, the password you supply may not work properly. There are + various approaches to handling this. For example, if you are + using Linux and have the iconv executable (part of the ICU + package) installed, you could pass to qpdf where + password is a password specified in + your terminal's locale. A detailed discussion of this is out of + scope for this manual, but just be aware of this issue if you have + trouble with a password that contains 8-bit characters. + + + + Encryption Options + + To change the encryption parameters of a file, use the --encrypt + flag. The syntax is + + + + Note that “” terminates parsing of + encryption flags and must be present even if no restrictions are + present. + + + Either or both of the user password and the owner password may be + empty strings. + + + The value for + may be 40 + or 128. The restriction flags are dependent upon key length. + When no additional restrictions are given, the default is to be + fully permissive. + + + If is 40, + the following restriction options are available: + + + + + + Determines whether or not to allow printing. + + + + + + + + Determines whether or not to allow document modification. + + + + + + + + Determines whether or not to allow text/image extraction. + + + + + + + + Determines whether or not to allow comments and form fill-in + and signing. + + + + + If is 128, + the following restriction options are available: + + + + + + Determines whether or not to allow accessibility to visually + impaired. + + + + + + + + Determines whether or not to allow text/graphic extraction. + + + + + + + + Controls printing access. + may be + one of the following: + + + + : allow full printing + + + + + : allow low-resolution printing only + + + + + : disallow printing + + + + + + + + + + + Controls modify access. + may be + one of the following, each of which implies all the options + that follow it: + + + + : allow full document modification + + + + + : allow comment authoring and form operations + + + + + : allow form field fill-in and signing + + + + + : allow document assembly only + + + + + : allow no modifications + + + + + + + + + + + If specified, any metadata stream in the document will be left + unencrypted even if the rest of the document is encrypted. + This also forces the PDF version to be at least 1.5. + + + + + + + + If is specified, AES encryption + will be used instead of RC4 encryption. This forces the PDF + version to be at least 1.6. + + + + + + + + Use of this option forces the /V and + /R parameters in the document's encryption + dictionary to be set to the value 4. As + qpdf will automatically do this when required, there is no + reason to ever use this option. It exists primarily for use + in testing qpdf itself. This option also forces the PDF + version to be at least 1.5. + + + + + The default for each permission option is to be fully permissive. + + + + Page Selection Options + + Starting with qpdf 3.0, it is possible to split and merge PDF + files by selecting pages from one or more input files. Whatever + file is given as the primary input file is used as the starting + point, but its pages are replaced with pages as specified. + + + + Multiple input files may be specified. Each one is given as the + name of the input file, an optional password (if required to open + the file), and the range of pages. Note that + “” terminates parsing of page + selection flags. + + + For each file that pages should be taken from, specify the file, a + password needed to open the file (if any), and a page range. The + password needs to be given only once per file. If any of the + input files are the same as the primary input file or the file + used to copy encryption parameters (if specified), you do not need + to repeat the password here. The same file can be repeated + multiple times. If a file that is repeated has a password, the + password only has to be given the first time. All non-page data + (info, outlines, page numbers, etc.) are taken from the primary + input file. To discard these, use as the + primary input. + + + It is not presently possible to specify the same page from the + same file directly more than once, but you can make this work by + specifying two different paths to the same file (such as by + putting ./ somewhere in the path). This can + also be used if you want to repeat a page from one of the input + files in the output file. This may be made more convenient in a + future version of qpdf if there is enough demand for this feature. + + + The page range is a set of numbers separated by commas, ranges of + numbers separated dashes, or combinations of those. The character + “z” represents the last page. Pages can appear in any + order. Ranges can appear with a high number followed by a low + number, which causes the pages to appear in reverse. Repeating a + number will cause an error, but you can use the workaround + discussed above should you really want to include the same page + twice. + + + Example page ranges: + + + + 1,3,5-9,15-12: pages 1, 2, 3, 5, 6, 7, 8, + 9, 15, 14, 13, and 12. + + + + + z-1: all pages in the document in reverse + + + + + + Note that qpdf doesn't presently do anything special about other + constructs in a PDF file that may know about pages, so semantics + of splitting and merging vary across features. For example, the + document's outlines (bookmarks) point to actual page objects, so + if you select some pages and not others, bookmarks that point to + pages that are in the output file will work, and remaining + bookmarks will not work. On the other hand, page labels (page + numbers specified in the file) are just sequential, so page labels + will be messed up in the output file. A future version of + qpdf may do a better job at handling these + issues. (Note that the qpdf library already contains all of the + APIs required in order to implement this in your own application + if you need it.) In the mean time, you can always use + as the primary input file to avoid + copying all of that from the first file. For example, to take + pages 1 through 5 from a infile.pdf while + preserving all metadata associated with that file, you could use + + qpdf + + If you wanted pages 1 through 5 from + infile.pdf but you wanted the rest of the + metadata to be dropped, you could instead run + + qpdf + + If you wanted to take pages 1–5 from + file1.pdf and pages 11–15 from + file2.pdf in reverse, you would run + + qpdf + + If, for some reason, you wanted to take the first page of an + encrypted file called encrypted.pdf with + password pass and repeat it twice in an output + file, and if you wanted to drop metadata (like page numbers and + outlines) but preserve encryption, you would use + + qpdf + + Note that we had to specify the password all three times because + giving a password as + doesn't count for page selection, and as far as qpdf is concerned, + encrypted.pdf and + ./encrypted.pdf are separated files. These + are all corner cases that most users should hopefully never have + to be bothered with. + + + + Advanced Transformation Options + + These transformation options control fine points of how qpdf + creates the output file. Mostly these are of use only to people + who are very familiar with the PDF file format or who are PDF + developers. The following options are available: + + + + + + Controls transformation of stream data. The value of + may be one + of the following: + + + + : recompress stream data when + possible (default) + + + + + : leave all stream data as is + + + + + : uncompress stream data when + possible + + + + + + + + + + + Enables or disables normalization of content streams. + + + + + + + + Prevents qpdf from attempting to recover damaged files. + + + + + + + + Controls handing of object streams. The value of + may be one of + the following: + + + + : preserve original object streams + (default) + + + + + : don't write any object streams + + + + + : use object streams wherever + possible + + + + + + + + + + + Tells qpdf to ignore any cross-reference streams. + + + + + + + + Turns on QDF mode. For additional information on QDF, please + see . + + + + + + + + Forces the PDF version of the output file to be at least + version. In other words, if the + input file has a lower version than the specified version, the + specified version will be used. If the input file has a + higher version, the input file's original version will be + used. It is seldom necessary to use this option since qpdf + will automatically increase the version as needed when adding + features that require newer PDF readers. + + + + + + + + This option forces the PDF version to be the exact version + specified even when the file may have content that + is not supported in that version. In some cases, + forcing the output file's PDF version to be lower than that of + the input file will cause qpdf to disable certain features of + the document. Specifically, AES encryption is disabled if the + version is less than 1.6, cleartext metadata and object + streams are disabled if less than 1.5, 128-bit encryption keys + are disabled if less than 1.4, and all encryption is disabled + if less than 1.3. Even with these precautions, qpdf won't be + able to do things like eliminate use of newer image + compression schemes, transparency groups, or other features + that may have been added in more recent versions of PDF. + + + As a general rule, with the exception of big structural things + like the use of object streams or AES encryption, PDF viewers + are supposed to ignore features in files that they don't + support from newer versions. This means that forcing the + version to a lower version may make it possible to open your + PDF file with an older version, though bear in mind that some + of the original document's functionality may be lost. + + + + + + + By default, when a stream is encoded using non-lossy filters that + qpdf understands and is not already compressed using a good + compression scheme, qpdf will uncompress and recompress streams. + Assuming proper filter implements, this is safe and generally + results in smaller files. This behavior may also be explicitly + requested with . + + + When is specified, qpdf + will never attempt to change the filtering of any stream data. + + + When is specified, qpdf + will attempt to remove any non-lossy filters that it supports. + This includes /FlateDecode, + /LZWDecode, /ASCII85Decode, + and /ASCIIHexDecode. This can be very useful + for inspecting the contents of various streams. + + + When is specified, qpdf + will attempt to normalize whitespace and newlines in page content + streams. This is generally safe but could, in some cases, cause + damage to the content streams. This option is intended for people + who wish to study PDF content streams or to debug PDF content. + You should not use this for “production” PDF files. + + + Ordinarily, qpdf will attempt to recover from certain types of + errors in PDF files. These include errors in the cross-reference + table, certain types of object numbering errors, and certain types + of stream length errors. Sometimes, qpdf may think it has + recovered but may not have actually recovered, so care should be + taken when using this option as some data loss is possible. The + option will prevent qpdf from + attempting recovery. In this case, it will fail on the first + error that it encounters. + + + Object streams, also known as compressed objects, were introduced + into the PDF specification at version 1.5, corresponding to + Acrobat 6. Some older PDF viewers may not support files with + object streams. qpdf can be used to transform files with object + streams to files without object streams or vice versa. As + mentioned above, there are three object stream modes: + , , and + . + + + In mode, the relationship to objects and + the streams that contain them is preserved from the original file. + In mode, all objects are written as + regular, uncompressed objects. The resulting file should be + readable by older PDF viewers. (Of course, the content of the + files may include features not supported by older viewers, but at + least the structure will be supported.) In + mode, qpdf will create its own object + streams. This will usually result in more compact PDF files, + though they may not be readable by older viewers. In this mode, + qpdf will also make sure the PDF version number in the header is + at least 1.5. + + + Ordinarily, qpdf reads cross-reference streams when they are + present in a PDF file. If + is specified, qpdf will ignore any cross-reference streams for + hybrid PDF files. The purpose of hybrid files is to make some + content available to viewers that are not aware of cross-reference + streams. It is almost never desirable to ignore them. The only + time when you might want to use this feature is if you are testing + creation of hybrid PDF files and wish to see how a PDF consumer + that doesn't understand object and cross-reference streams would + interpret such a file. + + + The flag turns on QDF mode, which changes + some of the defaults described above. Specifically, in QDF mode, + by default, stream data is uncompressed, content streams are + normalized, and encryption is removed. These defaults can still + be overridden by specifying the appropriate options as described + above. Additionally, in QDF mode, stream lengths are stored as + indirect objects, objects are laid out in a less efficient but + more readable fashion, and the documents are interspersed with + comments that make it easier for the user to find things and also + make it possible for fix-qdf to work properly. + QDF mode is intended for people, mostly developers, who wish to + inspect or modify PDF files in a text editor. For details, please + see . + + + + Testing, Inspection, and Debugging Options + + These options can be useful for digging into PDF files or for use + in automated test suites for software that uses the qpdf library. + When any of the options in this section are specified, no output + file should be given. The following options are available: + + + + + + Causes generation of a fixed value for /ID. This is intended + for testing only. Never use it for production files. + + + + + + + + Causes use of a static initialization vector for AES-CBC. + This is intended for testing only so that output files can be + reproducible. Never use it for production files. This option + in particular is not secure since it significantly weakens the + encryption. + + + + + + + + Suppresses inclusion of original object ID comments in QDF + files. This can be useful when generating QDF files for test + purposes, particularly when comparing them to determine + whether two PDF files have identical content. + + + + + + + + Shows document encryption parameters. Also shows the + document's user password if the owner password is given. + + + + + + + + Checks file integrity and linearization status. + + + + + + + + Checks and displays all data in the linearization hint tables. + + + + + + + + Shows the contents of the cross-reference table in a + human-readable form. This is especially useful for files with + cross-reference streams which are stored in a binary format. + + + + + + + + Show the contents of the given object. This is especially + useful for inspecting objects that are inside of object + streams (also known as “compressed objects”). + + + + + + + + When used along with the + option, if the object is a stream, shows the raw stream data + instead of object's contents. + + + + + + + + When used along with the + option, if the object is a stream, shows the filtered stream + data instead of object's contents. If the stream is filtered + using filters that qpdf does not support, an error will be + issued. + + + + + + + + Shows the object and generation number for each page + dictionary object and for each content stream associated with + the page. Having this information makes it more convenient to + inspect objects from a particular page. + + + + + + + + When used along with , also shows + the object and generation numbers for the image objects on + each page. (At present, information about images in shared + resource dictionaries are not output by this command. This is + discussed in a comment in the source code.) + + + + + + + + Checks file structure and well as encryption, linearization, + and encoding of stream data. A file for which + reports no errors may still have + errors in stream data content but should otherwise be + structurally sound. If any errors, + qpdf will exit with a status of 2. There are some recoverable + conditions that detects. These are + issued as warnings instead of errors. If qpdf finds no errors + but finds warnings, it will exit with a status of 3 (as of + version 2.0.4). + + + + + + + The and + options are ignored unless + is given. Either of these options + will cause the stream data to be written to standard output. In + order to avoid commingling of stream data with other output, it is + recommend that these objects not be combined with other + test/inspection options. + + + If is given and + is also given, qpdf will + attempt to normalize the stream data as if it is a page content + stream. This attempt will be made even if it is not a page + content stream, in which case it will produce unusable results. + + + + + QDF Mode + + In QDF mode, qpdf creates PDF files in what we call QDF + form. A PDF file in QDF form, sometimes called a QDF + file, is a completely valid PDF file that has + %QDF-1.0 as its third line (after the pdf header + and binary characters) and has certain other characteristics. The + purpose of QDF form is to make it possible to edit PDF files, with + some restrictions, in an ordinary text editor. This can be very + useful for experimenting with different PDF constructs or for + making one-off edits to PDF files (though there are other reasons + why this may not always work). + + + It is ordinarily very difficult to edit PDF files in a text editor + for two reasons: most meaningful data in PDF files is compressed, + and PDF files are full of offset and length information that makes + it hard to add or remove data. A QDF file is organized in a manner + such that, if edits are kept within certain constraints, the + fix-qdf program, distributed with qpdf, is able + to restore edited files to a correct state. The + fix-qdf program takes no command-line + arguments. It reads a possibly edited QDF file from standard input + and writes a repaired file to standard output. + + + The following attributes characterize a QDF file: + + + + All objects appear in numerical order in the PDF file, including + when objects appear in object streams. + + + + + Objects are printed in an easy-to-read format, and all line + endings are normalized to UNIX line endings. + + + + + Unless specifically overridden, streams appear uncompressed + (when qpdf supports the filters and they are compressed with a + non-lossy compression scheme), and most content streams are + normalized (line endings are converted to just a UNIX-style + linefeeds). + + + + + All streams lengths are represented as indirect objects, and the + stream length object is always the next object after the stream. + If the stream data does not end with a newline, an extra newline + is inserted, and a special comment appears after the stream + indicating that this has been done. + + + + + If the PDF file contains object streams, if object stream + n contains k objects, + those objects are numbered from n+1 through + n+k, and the object number/offset pairs + appear on a separate line for each object. Additionally, each + object in the object stream is preceded by a comment indicating + its object number and index. This makes it very easy to find + objects in object streams. + + + + + All beginnings of objects, stream tokens, + endstream tokens, and + endobj tokens appear on lines by themselves. + A blank line follows every endobj token. + + + + + If there is a cross-reference stream, it is unfiltered. + + + + + Page dictionaries and page content streams are marked with + special comments that make them easy to find. + + + + + Comments precede each object indicating the object number of the + corresponding object in the original file. + + + + + + When editing a QDF file, any edits can be made as long as the above + constraints are maintained. This means that you can freely edit a + page's content without worrying about messing up the QDF file. It + is also possible to add new objects so long as those objects are + added after the last object in the file or subsequent objects are + renumbered. If a QDF file has object streams in it, you can always + add the new objects before the xref stream and then change the + number of the xref stream, since nothing generally ever references + it by number. + + + It is not generally practical to remove objects from QDF files + without messing up object numbering, but if you remove all + references to an object, you can run qpdf on the file (after + running fix-qdf), and qpdf will omit the + now-orphaned object. + + + When fix-qdf is run, it goes through the file + and recomputes the following parts of the file: + + + + the /N, /W, and + /First keys of all object stream dictionaries + + + + + the pairs of numbers representing object numbers and offsets of + objects in object streams + + + + + all stream lengths + + + + + the cross-reference table or cross-reference stream + + + + + the offset to the cross-reference table or cross-reference + stream following the startxref token + + + + + + + Using the QPDF Library + + The source tree for the qpdf package has an + examples directory that contains a few + example programs. The qpdf/qpdf.cc source + file also serves as a useful example since it exercises almost all + of the qpdf library's public interface. The best source of + documentation on the library itself is reading comments in + include/qpdf/QPDF.hh, + include/qpdf/QDFWriter.hh, and + include/qpdf/QPDFObjectHandle.hh. + + + All header files are installed in the include/qpdf directory. It + is recommend that you use #include + <qpdf/QPDF.hh> rather than adding + include/qpdf to your include path. + + + When linking against the qpdf static library, you may also need to + specify -lpcre -lz on your link command. If + your system understands how to read libtool + .la files, this may not be necessary. + + + The qpdf library is safe to use in a multithreaded program, but no + individual QPDF object instance (including + QPDF, QPDFObjectHandle, or + QPDFWriter) can be used in more than one thread at a + time. Multiple threads may simultaneously work with different + instances of these and all other QPDF objects. + + + + Design and Library Notes + + Introduction + + This section was written prior to the implementation of the qpdf + package and was subsequently modified to reflect the + implementation. In some cases, for purposes of explanation, it + may differ slightly from the actual implementation. As always, + the source code and test suite are authoritative. Even if there + are some errors, this document should serve as a road map to + understanding how this code works. + + + In general, one should adhere strictly to a specification when + writing but be liberal in reading. This way, the product of our + software will be accepted by the widest range of other programs, + and we will accept the widest range of input files. This library + attempts to conform to that philosophy whenever possible but also + aims to provide strict checking for people who want to validate + PDF files. If you don't want to see warnings and are trying to + write something that is tolerant, you can call + setSuppressWarnings(true). If you want to fail + on the first error, you can call + setAttemptRecovery(false). The default + behavior is to generating warnings for recoverable problems. Note + that recovery will not always produce the desired results even if + it is able to get through the file. Unlike most other PDF files + that produce generic warnings such as “This file is + damaged,”, qpdf generally issues a detailed error message + that would be most useful to a PDF developer. This is by design + as there seems to be a shortage of PDF validation tools out + there. (This was, in fact, one of the major motivations behind + the initial creation of qpdf.) + + + + Design Goals + + The QPDF package includes support for reading and rewriting PDF + files. It aims to hide from the user details involving object + locations, modified (appended) PDF files, the + directness/indirectness of objects, and stream filters including + encryption. It does not aim to hide knowledge of the object + hierarchy or content stream contents. Put another way, a user of + the qpdf library is expected to have knowledge about how PDF files + work, but is not expected to have to keep track of bookkeeping + details such as file positions. + + + A user of the library never has to care whether an object is + direct or indirect. All access to objects deals with this + transparently. All memory management details are also handled by + the library. + + + The PointerHolder object is used internally + by the library to deal with memory management. This is basically + a smart pointer object very similar in spirit to the Boost + library's shared_ptr object, but predating + it by several years. This library also makes use of a technique + for giving fine-grained access to methods in one class to other + classes by using public subclasses with friends and only private + members that in turn call private methods of the containing class. + See QPDFObjectHandle::Factory as an + example. + + + The top-level qpdf class is QPDF. A + QPDF object represents a PDF file. The + library provides methods for both accessing and mutating PDF + files. + + + QPDFObject is the basic PDF Object class. + It is an abstract base class from which are derived classes for + each type of PDF object. Clients do not interact with Objects + directly but instead interact with + QPDFObjectHandle. + + + QPDFObjectHandle contains + PointerHolder<QPDFObject> and + includes accessor methods that are type-safe proxies to the + methods of the derived object classes as well as methods for + querying object types. They can be passed around by value, + copied, stored in containers, etc. with very low overhead. + Instances of QPDFObjectHandle always + contain a reference back to the QPDF object + from which they were created. A + QPDFObjectHandle may be direct or indirect. + If indirect, the QPDFObject the + PointerHolder initially points to is a null + pointer. In this case, the first attempt to access the underlying + QPDFObject will result in the + QPDFObject being resolved via a call to the + referenced QPDF instance. This makes it + essentially impossible to make coding errors in which certain + things will work for some PDF files and not for others based on + which objects are direct and which objects are indirect. + + + Instances of QPDFObjectHandle can be + directly created and modified using static factory methods in the + QPDFObjectHandle class. There are factory + methods for each type of object as well as a convenience method + QPDFObjectHandle::parse that creates an + object from a string representation of the object. Existing + instances of QPDFObjectHandle can also be + modified in several ways. See comments in + QPDFObjectHandle.hh for details. + + + When the QPDF class creates a new object, + it dynamically allocates the appropriate type of + QPDFObject and immediately hands the + pointer to an instance of QPDFObjectHandle. + The parser reads a token from the current file position. If the + token is a not either a dictionary or array opener, an object is + immediately constructed from the single token and the parser + returns. Otherwise, the parser is invoked recursively in a + special mode in which it accumulates objects until it finds a + balancing closer. During this process, the + “R” keyword is recognized and an + indirect QPDFObjectHandle may be + constructed. + + + The QPDF::resolve() method, which is used to + resolve an indirect object, may be invoked from the + QPDFObjectHandle class. It first checks a + cache to see whether this object has already been read. If not, + it reads the object from the PDF file and caches it. It the + returns the resulting QPDFObjectHandle. + The calling object handle then replaces its + PointerHolder<QDFObject> with the one + from the newly returned QPDFObjectHandle. + In this way, only a single copy of any direct object need exist + and clients can access objects transparently without knowing + caring whether they are direct or indirect objects. Additionally, + no object is ever read from the file more than once. That means + that only the portions of the PDF file that are actually needed + are ever read from the input file, thus allowing the qpdf package + to take advantage of this important design goal of PDF files. + + + If the requested object is inside of an object stream, the object + stream itself is first read into memory. Then the tokenizer reads + objects from the memory stream based on the offset information + stored in the stream. Those individual objects are cached, after + which the temporary buffer holding the object stream contents are + discarded. In this way, the first time an object in an object + stream is requested, all objects in the stream are cached. + + + An instance of QPDF is constructed by using + the class's default constructor. If desired, the + QPDF object may be configured with various + methods that change its default behavior. Then the + QPDF::processFile() method is passed the name + of a PDF file, which permanently associates the file with that + QPDF object. A password may also be given for access to + password-protected files. QPDF does not enforce encryption + parameters and will treat user and owner passwords equivalently. + Either password may be used to access an encrypted file. + + + As pointed out earlier, the intention is not for qpdf to be used + to bypass security on files. but as any open source PDF consumer + may be easily modified to bypass basic PDF document security, + and qpdf offers may transformations that can do this as well, + there seems to be little point in the added complexity of + conditionally enforcing document security. + + + QPDF will allow recovery of a user password + given an owner password. The input PDF file must be seekable. + (Output files written by QPDFWriter need + not be seekable, even when creating linearized files.) During + construction, QPDF validates the PDF file's + header, and then reads the cross reference tables and trailer + dictionaries. The QPDF class keeps only + the first trailer dictionary though it does read all of them so it + can check the /Prev key. + QPDF class users may request the root + object and the trailer dictionary specifically. The cross + reference table is kept private. Objects may then be requested by + number of by walking the object tree. + + + When a PDF file has a cross-reference stream instead of a + cross-reference table and trailer, requesting the document's + trailer dictionary returns the stream dictionary from the + cross-reference stream instead. + + + There are some convenience routines for very common operations + such as walking the page tree and returning a vector of all page + objects. For full details, please see the header file + QPDF.hh. + + + The following example should clarify how + QPDF processes a simple file. + + + + Client constructs QPDF + pdf and calls + pdf.processFile("a.pdf");. + + + + + The QPDF class checks the beginning of + a.pdf for + %!PDF-1.[0-9]+. It then reads the cross + reference table mentioned at the end of the file, ensuring that + it is looking before the last %%EOF. After + getting to trailer keyword, it invokes the + parser. + + + + + The parser sees “<<”, so + it calls itself recursively in dictionary creation mode. + + + + + In dictionary creation mode, the parser keeps accumulating + objects until it encounters + “>>”. Each object that is + read is pushed onto a stack. If + “R” is read, the last two + objects on the stack are inspected. If they are integers, they + are popped off the stack and their values are used to construct + an indirect object handle which is then pushed onto the stack. + When “>>” is finally read, + the stack is converted into a + QPDF_Dictionary which is placed in a + QPDFObjectHandle and returned. + + + + + The resulting dictionary is saved as the trailer dictionary. + + + + + The /Prev key is searched. If present, + QPDF seeks to that point and repeats + except that the new trailer dictionary is not saved. If + /Prev is not present, the initial parsing + process is complete. + + + If there is an encryption dictionary, the document's encryption + parameters are initialized. + + + + + The client requests root object. The + QPDF class gets the value of root key + from trailer dictionary and returns it. It is an unresolved + indirect QPDFObjectHandle. + + + + + The client requests the /Pages key from root + QPDFObjectHandle. The + QPDFObjectHandle notices that it is + indirect so it asks QPDF to resolve it. + QPDF looks in the object cache for an + object with the root dictionary's object ID and generation + number. Upon not seeing it, it checks the cross reference + table, gets the offset, and reads the object present at that + offset. It stores the result in the object cache and returns + the cached result. The calling + QPDFObjectHandle replaces its object + pointer with the one from the resolved + QPDFObjectHandle, verifies that it a + valid dictionary object, and returns the (unresolved indirect) + QPDFObject handle to the top of the + Pages hierarchy. + + + As the client continues to request objects, the same process is + followed for each new requested object. + + + + + + + Encryption + + Encryption is supported transparently by qpdf. When opening a PDF + file, if an encryption dictionary exists, the + QPDF object processes this dictionary using + the password (if any) provided. The primary decryption key is + computed and cached. No further access is made to the encryption + dictionary after that time. When an object is read from a file, + the object ID and generation of the object in which it is + contained is always known. Using this information along with the + stored encryption key, all stream and string objects are + transparently decrypted. Raw encrypted objects are never stored + in memory. This way, nothing in the library ever has to know or + care whether it is reading an encrypted file. + + + An interface is also provided for writing encrypted streams and + strings given an encryption key. This is used by + QPDFWriter when it rewrites encrypted + files. + + + + Adding and Removing Pages + + While qpdf's API has supported adding and modifying objects for + some time, version 3.0 introduces specific methods for adding and + removing pages. These are largely convenience routines that + handle two tricky issues: pushing inheritable resources from the + /Pages tree down to individual pages and + manipulation of the /Pages tree itself. For + details, see addPage and surrounding methods + in QPDF.hh. + + + + Reserving Object Numbers + + Version 3.0 of qpdf introduced the concept of reserved objects. + These are seldom needed for ordinary operations, but there are + cases in which you may want to add a series of indirect objects + with references to each other to a QPDF + object. This causes a problem because you can't determine the + object ID that a new indirect object will have until you add it to + the QPDF object with + QPDF::makeIndirectObject. The only way to + add two mutually referential objects to a + QPDF object prior to version 3.0 would be + to add the new objects first and then make them refer to each + other after adding them. Now it is possible to create a + reserved object using + QPDFObjectHandle::newReserved. This is an + indirect object that stays “unresolved” even if it is + queried for its type. So now, if you want to create a set of + mutually referential objects, you can create reservations for each + one of them and use those reservations to construct the + references. When finished, you can call + QPDF::replaceReserved to replace the reserved + objects with the real ones. This functionality will never be + needed by most applications, but it is used internally by QPDF + when copying objects from other PDF files, as discussed in . For an example of how to use + reserved objects, search for newReserved in + test_driver.cc in qpdf's sources. + + + + Copying Objects From Other PDF Files + + Version 3.0 of qpdf introduced the ability to copy objects into a + QPDF object from a different + QPDF object, which we refer to as + foreign objects. This allows arbitrary + merging of PDF files. The qpdf command-line + tool provides limited support for basic page selection, including + merging in pages from other files, but the library's API makes it + possible to implement arbitrarily complex merging operations. The + main method for copying foreign objects is + QPDF::copyForeignObject. This takes an + indirect object from another QPDF and + copies it recursively into this object while preserving all object + structure, including circular references. This means you can add + a direct object that you create from scratch to a + QPDF object with + QPDF::makeIndirectObject, and you can add an + indirect object from another file with + QPDF::copyForeignObject. The fact that + QPDF::makeIndirectObject does not + automatically detect a foreign object and copy it is an explicit + design decision. Copying a foreign object seems like a + sufficiently significant thing to do that it should be done + explicitly. + + + The other way to copy foreign objects is by passing a page from + one QPDF to another by calling + QPDF::addPage. In contrast to + QPDF::makeIndirectObject, this method + automatically distinguishes between indirect objects in the + current file, foreign objects, and direct objects. + + + + Writing PDF Files + + The qpdf library supports file writing of + QPDF objects to PDF files through the + QPDFWriter class. The + QPDFWriter class has two writing modes: one + for non-linearized files, and one for linearized files. See for a description of linearization + is implemented. This section describes how we write + non-linearized files including the creation of QDF files (see + . + + + This outline was written prior to implementation and is not + exactly accurate, but it provides a correct “notional” + idea of how writing works. Look at the code in + QPDFWriter for exact details. + + + + Initialize state: + + + + next object number = 1 + + + + + object queue = empty + + + + + renumber table: old object id/generation to new id/0 = empty + + + + + xref table: new id -> offset = empty + + + + + + + + Create a QPDF object from a file. + + + + + Write header for new PDF file. + + + + + Request the trailer dictionary. + + + + + For each value that is an indirect object, grab the next object + number (via an operation that returns and increments the + number). Map object to new number in renumber table. Push + object onto queue. + + + + + While there are more objects on the queue: + + + + Pop queue. + + + + + Look up object's new number n in the + renumbering table. + + + + + Store current offset into xref table. + + + + + Write n 0 obj. + + + + + If object is null, whether direct or indirect, write out + null, thus eliminating unresolvable indirect object + references. + + + + + If the object is a stream stream, write stream contents, + piped through any filters as required, to a memory buffer. + Use this buffer to determine the stream length. + + + + + If object is not a stream, array, or dictionary, write out + its contents. + + + + + If object is an array or dictionary (including stream), + traverse its elements (for array) or values (for + dictionaries), handling recursive dictionaries and arrays, + looking for indirect objects. When an indirect object is + found, if it is not resolvable, ignore. (This case is + handled when writing it out.) Otherwise, look it up in the + renumbering table. If not found, grab the next available + object number, assign to the referenced object in the + renumbering table, and push the referenced object onto the + queue. As a special case, when writing out a stream + dictionary, replace length, filters, and decode parameters + as required. + + + Write out dictionary or array, replacing any unresolvable + indirect object references with null (pdf spec says + reference to non-existent object is legal and resolves to + null) and any resolvable ones with references to the + renumbered objects. + + + + + If the object is a stream, write + stream\n, the stream contents (from the + memory buffer), and \nendstream\n. + + + + + When done, write endobj. + + + + + + + + + Once we have finished the queue, all referenced objects will have + been written out and all deleted objects or unreferenced objects + will have been skipped. The new cross-reference table will + contain an offset for every new object number from 1 up to the + number of objects written. This can be used to write out a new + xref table. Finally we can write out the trailer dictionary with + appropriately computed /ID (see spec, 8.3, File Identifiers), the + cross reference table offset, and %%EOF. + + + + Filtered Streams + + Support for streams is implemented through the + Pipeline interface which was designed for + this package. + + + When reading streams, create a series of + Pipeline objects. The + Pipeline abstract base requires + implementation write() and + finish() and provides an implementation of + getNext(). Each pipeline object, upon + receiving data, does whatever it is going to do and then writes + the data (possibly modified) to its successor. Alternatively, a + pipeline may be an end-of-the-line pipeline that does something + like store its output to a file or a memory buffer ignoring a + successor. For additional details, look at + Pipeline.hh. + + + QPDF can read raw or filtered streams. + When reading a filtered stream, the QPDF + class creates a Pipeline object for one of + each appropriate filter object and chains them together. The last + filter should write to whatever type of output is required. The + QPDF class has an interface to write raw or + filtered stream contents to a given pipeline. + + + + + Linearization + + This chapter describes how QPDF and + QPDFWriter implement creation and processing + of linearized PDFS. + + + Basic Strategy for Linearization + + To avoid the incestuous problem of having the qpdf library + validate its own linearized files, we have a special linearized + file checking mode which can be invoked via qpdf + --check-linearization (or qpdf + --check). This mode reads the linearization parameter + dictionary and the hint streams and validates that object + ordering, parameters, and hint stream contents are correct. The + validation code was first tested against linearized files created + by external tools (Acrobat and pdlin) and then used to validate + files created by QPDFWriter itself. + + + + Preparing For Linearization + + Before creating a linearized PDF file from any other PDF file, the + PDF file must be altered such that all page attributes are + propagated down to the page level (and not inherited from parents + in the /Pages tree). We also have to know + which objects refer to which other objects, being concerned with + page boundaries and a few other cases. We refer to this part of + preparing the PDF file as optimization, + discussed in . Note the, in + this context, the term optimization is a + qpdf term, and the term linearization is a + term from the PDF specification. Do not be confused by the fact + that many applications refer to linearization as optimization or + web optimization. + + + When creating linearized PDF files from optimized PDF files, there + are really only a few issues that need to be dealt with: + + + + Creation of hints tables + + + + + Placing objects in the correct order + + + + + Filling in offsets and byte sizes + + + + + + + Optimization + + In order to perform various operations such as linearization and + splitting files into pages, it is necessary to know which objects + are referenced by which pages, page thumbnails, and root and + trailer dictionary keys. It is also necessary to ensure that all + page-level attributes appear directly at the page level and are + not inherited from parents in the pages tree. + + + We refer to the process of enforcing these constraints as + optimization. As mentioned above, note + that some applications refer to linearization as optimization. + Although this optimization was initially motivated by the need to + create linearized files, we are using these terms separately. + + + PDF file optimization is implemented in the + QPDF_optimization.cc source file. That file + is richly commented and serves as the primary reference for the + optimization process. + + + After optimization has been completed, the private member + variables obj_user_to_objects and + object_to_obj_users in + QPDF have been populated. Any object that + has more than one value in the + object_to_obj_users table is shared. Any + object that has exactly one value in the + object_to_obj_users table is private. To find + all the private objects in a page or a trailer or root dictionary + key, one merely has make this determination for each element in + the obj_user_to_objects table for the given + page or key. + + + Note that pages and thumbnails have different object user types, + so the above test on a page will not include objects referenced by + the page's thumbnail dictionary and nothing else. + + + + Writing Linearized Files + + We will create files with only primary hint streams. We will + never write overflow hint streams. (As of PDF version 1.4, + Acrobat doesn't either, and they are never necessary.) The hint + streams contain offset information to objects that point to where + they would be if the hint stream were not present. This means + that we have to calculate all object positions before we can + generate and write the hint table. This means that we have to + generate the file in two passes. To make this reliable, + QPDFWriter in linearization mode invokes + exactly the same code twice to write the file to a pipeline. + + + In the first pass, the target pipeline is a count pipeline chained + to a discard pipeline. The count pipeline simply passes its data + through to the next pipeline in the chain but can return the + number of bytes passed through it at any intermediate point. The + discard pipeline is an end of line pipeline that just throws its + data away. The hint stream is not written and dummy values with + adequate padding are stored in the first cross reference table, + linearization parameter dictionary, and /Prev key of the first + trailer dictionary. All the offset, length, object renumbering + information, and anything else we need for the second pass is + stored. + + + At the end of the first pass, this information is passed to the + QPDF class which constructs a compressed + hint stream in a memory buffer and returns it. + QPDFWriter uses this information to write a + complete hint stream object into a memory buffer. At this point, + the length of the hint stream is known. + + + In the second pass, the end of the pipeline chain is a regular + file instead of a discard pipeline, and we have known values for + all the offsets and lengths that we didn't have in the first pass. + We have to adjust offsets that appear after the start of the hint + stream by the length of the hint stream, which is known. Anything + that is of variable length is padded, with the padding code + surrounding any writing code that differs in the two passes. This + ensures that changes to the way things are represented never + results in offsets that were gathered during the first pass + becoming incorrect for the second pass. + + + Using this strategy, we can write linearized files to a + non-seekable output stream with only a single pass to disk or + wherever the output is going. + + + + Calculating Linearization Data + + Once a file is optimized, we have information about which objects + access which other objects. We can then process these tables to + decide which part (as described in “Linearized PDF Document + Structure” in the PDF specification) each object is + contained within. This tells us the exact order in which objects + are written. The QPDFWriter class asks for + this information and enqueues objects for writing in the proper + order. It also turns on a check that causes an exception to be + thrown if an object is encountered that has not already been + queued. (This could happen only if there were a bug in the + traversal code used to calculate the linearization data.) + + + + Known Issues with Linearization + + There are a handful of known issues with this linearization code. + These issues do not appear to impact the behavior of linearized + files which still work as intended: it is possible for a web + browser to begin to display them before they are fully + downloaded. In fact, it seems that various other programs that + create linearized files have many of these same issues. These + items make reference to terminology used in the linearization + appendix of the PDF specification. + + + + Thread Dictionary information keys appear in part 4 with the + rest of Threads instead of in part 9. Objects in part 9 are + not grouped together functionally. + + + + + We are not calculating numerators for shared object positions + within content streams or interleaving them within content + streams. + + + + + We generate only page offset, shared object, and outline hint + tables. It would be relatively easy to add some additional + tables. We gather most of the information needed to create + thumbnail hint tables. There are comments in the code about + this. + + + + + + + Debugging Note + + The qpdf --show-linearization command can show + the complete contents of linearization hint streams. To look at + the raw data, you can extract the filtered contents of the + linearization hint tables using qpdf --show-object=n + --filtered-stream-data. Then, to convert this into a + bit stream (since linearization tables are bit streams written + without regard to byte boundaries), you can pipe the resulting + data through the following perl code: + + use bytes; +binmode STDIN; +undef $/; +my $a = <STDIN>; +my @ch = split(//, $a); +map { printf("%08b", ord($_)) } @ch; +print "\n"; + + + + + + Object and Cross-Reference Streams + + This chapter provides information about the implementation of + object stream and cross-reference stream support in qpdf. + + + Object Streams + + Object streams can contain any regular object except the + following: + + + + stream objects + + + + + objects with generation > 0 + + + + + the encryption dictionary + + + + + objects containing the /Length of another stream + + + + In addition, Adobe reader (at least as of version 8.0.0) appears + to not be able to handle having the document catalog appear in an + object stream if the file is encrypted, though this is not + specifically disallowed by the specification. + + + There are additional restrictions for linearized files. See for details. + + + The PDF specification refers to objects in object streams as + “compressed objects” regardless of whether the object + stream is compressed. + + + The generation number of every object in an object stream must be + zero. It is possible to delete and replace an object in an object + stream with a regular object. + + + The object stream dictionary has the following keys: + + + + /N: number of objects + + + + + /First: byte offset of first object + + + + + /Extends: indirect reference to stream that + this extends + + + + + + Stream collections are formed with /Extends. + They must form a directed acyclic graph. These can be used for + semantic information and are not meaningful to the PDF document's + syntactic structure. Although qpdf preserves stream collections, + it never generates them and doesn't make use of this information + in any way. + + + The specification recommends limiting the number of objects in + object stream for efficiency in reading and decoding. Acrobat 6 + uses no more than 100 objects per object stream for linearized + files and no more 200 objects per stream for non-linearized files. + QPDFWriter, in object stream generation + mode, never puts more than 100 objects in an object stream. + + + Object stream contents consists of N pairs of + integers, each of which is the object number and the byte offset + of the object relative to the first object in the stream, followed + by the objects themselves, concatenated. + + + + Cross-Reference Streams + + For non-hybrid files, the value following + startxref is the byte offset to the xref stream + rather than the word xref. + + + For hybrid files (files containing both xref tables and + cross-reference streams), the xref table's trailer dictionary + contains the key /XRefStm whose value is the + byte offset to a cross-reference stream that supplements the xref + table. A PDF 1.5-compliant application should read the xref table + first. Then it should replace any object that it has already seen + with any defined in the xref stream. Then it should follow any + /Prev pointer in the original xref table's + trailer dictionary. The specification is not clear about what + should be done, if anything, with a /Prev + pointer in the xref stream referenced by an xref table. The + QPDF class ignores it, which is probably + reasonable since, if this case were to appear for any sensible PDF + file, the previous xref table would probably have a corresponding + /XRefStm pointer of its own. For example, if a + hybrid file were appended, the appended section would have its own + xref table and /XRefStm. The appended xref + table would point to the previous xref table which would point the + /XRefStm, meaning that the new + /XRefStm doesn't have to point to it. + + + Since xref streams must be read very early, they may not be + encrypted, and the may not contain indirect objects for keys + required to read them, which are these: + + + + /Type: value /XRef + + + + + /Size: value n+1: where + n is highest object number (same as + /Size in the trailer dictionary) + + + + + /Index (optional): value + [n count ...] + used to determine which objects' information is stored in this + stream. The default is [0 /Size]. + + + + + /Prev: value + offset: byte offset of previous xref + stream (same as /Prev in the trailer + dictionary) + + + + + /W [...]: sizes of each field in the xref + table + + + + + + The other fields in the xref stream, which may be indirect if + desired, are the union of those from the xref table's trailer + dictionary. + + + Cross-Reference Stream Data + + The stream data is binary and encoded in big-endian byte order. + Entries are concatenated, and each entry has a length equal to + the total of the entries in /W above. Each + entry consists of one or more fields, the first of which is the + type of the field. The number of bytes for each field is given + by /W above. A 0 in /W + indicates that the field is omitted and has the default value. + The default value for the field type is + “1”. All other default values are + “0”. + + + PDF 1.5 has three field types: + + + + 0: for free objects. Format: 0 obj + next-generation, same as the free table in a + traditional cross-reference table + + + + + 1: regular non-compressed object. Format: 1 offset + generation + + + + + 2: for objects in object streams. Format: 2 + object-stream-number index, the number of object + stream containing the object and the index within the object + stream of the object. + + + + + + It seems standard to have the first entry in the table be + 0 0 0 instead of 0 0 ffff + if there are no deleted objects. + + + + + Implications for Linearized Files + + For linearized files, the linearization dictionary, document + catalog, and page objects may not be contained in object streams. + + + Objects stored within object streams are given the highest range + of object numbers within the main and first-page cross-reference + sections. + + + It is okay to use cross-reference streams in place of regular xref + tables. There are on special considerations. + + + Hint data refers to object streams themselves, not the objects in + the streams. Shared object references should also be made to the + object streams. There are no reference in any hint tables to the + object numbers of compressed objects (objects within object + streams). + + + When numbering objects, all shared objects within both the first + and second halves of the linearized files must be numbered + consecutively after all normal uncompressed objects in that half. + + + + Implementation Notes + + There are three modes for writing object streams: + , , and + . In disable mode, we do not generate + any object streams, and we also generate an xref table rather than + xref streams. This can be used to generate PDF files that are + viewable with older readers. In preserve mode, we write object + streams such that written object streams contain the same objects + and /Extends relationships as in the original + file. This is equal to disable if the file has no object streams. + In generate, we create object streams ourselves by grouping + objects that are allowed in object streams together in sets of no + more than 100 objects. We also ensure that the PDF version is at + least 1.5 in generate mode, but we preserve the version header in + the other modes. The default is . + + + We do not support creation of hybrid files. When we write files, + even in preserve mode, we will lose any xref tables and merge any + appended sections. + + + + + Release Notes + + For a detailed list of changes, please see the file + ChangeLog in the source distribution. + + + + 3.0.2: September 6, 2012 + + + + + Bug fix: QPDFWriter::setOutputMemory did + not work when not used with + QPDFWriter::setStaticID, which made it + pretty much useless. This has been fixed. + + + + + New API call + QPDFWriter::setExtraHeaderText inserts + additional text near the header of the PDF file. The intended + use case is to insert comments that may be consumed by a + downstream application, though other use cases may exist. + + + + + + + + + 3.0.1: August 11, 2012 + + + + + Version 3.0.0 included addition of files for + pkg-config, but this was not mentioned in + the release notes. The release notes for 3.0.0 were updated + to mention this. + + + + + Bug fix: if an object stream ended with a scalar object not + followed by space, qpdf would incorrectly report that it + encountered a premature EOF. This bug has been in qpdf since + version 2.0. + + + + + + + + + 3.0.0: August 2, 2012 + + + + + Acknowledgment: I would like to express gratitude for the + contributions of Tobias Hoffmann toward the release of qpdf + version 3.0. He is responsible for most of the implementation + and design of the new API for manipulating pages, and + contributed code and ideas for many of the improvements made + in version 3.0. Without his work, this release would + certainly not have happened as soon as it did, if at all. + + + + + Non-compatible API change: The version of + QPDFObjectHandle::replaceStreamData that + uses a StreamDataProvider no longer + requires (or accepts) a length parameter. + See for an explanation. + While care is taken to avoid non-compatible API changes in + general, an exception was made this time because the new + interface offers an opportunity to significantly simplify + calling code. + + + + + Support has been added for large files. The test suite + verifies support for files larger than 4 gigabytes, and manual + testing has verified support for files larger than 10 + gigabytes. Large file support is available for both 32-bit + and 64-bit platforms as long as the compiler and underlying + platforms support it. + + + + + Support for page selection (splitting and merging PDF files) + has been added to the qpdf command-line + tool. See . + + + + + Options have been added to the qpdf + command-line tool for copying encryption parameters from + another file. See . + + + + + New methods have been added to the QPDF + object for adding and removing pages. See . + + + + + New methods have been added to the QPDF + object for copying objects from other PDF files. See + + + + + A new method QPDFObjectHandle::parse has + been added for constructing + QPDFObjectHandle objects from a string + description. + + + + + Methods have been added to QPDFWriter + to allow writing to an already open stdio FILE* + addition to writing to standard output or a named file. + Methods have been added to QPDF to be + able to process a file from an already open stdio + FILE*. This makes it possible to read and write + PDF from secure temporary files that have been unlinked prior + to being fully read or written. + + + + + The QPDF::emptyPDF can be used to allow + creation of PDF files from scratch. The example + examples/pdf-create.cc illustrates how it + can be used. + + + + + Several methods to take + PointerHolder<Buffer> can now + also accept std::string arguments. + + + + + Many new convenience methods have been added to the library, + most in QPDFObjectHandle. See + ChangeLog for a full list. + + + + + When building on a platform that supports ELF shared libraries + (such as Linux), symbol versions are enabled by default. They + can be disabled by passing + to + ./configure. + + + + + The file libqpdf.pc is now installed to + support pkg-config. + + + + + Image comparison tests are off by default now since they are + not needed to verify a correct build or port of qpdf. They + are needed only when changing the actual PDF output generated + by qpdf. You should enable them if you are making deep + changes to qpdf itself. See README for + details. + + + + + Large file tests are off by default but can be turned on with + ./configure or by setting an environment + variable before running the test suite. See + README for details. + + + + + When qpdf's test suite fails, failures are not printed to the + terminal anymore by default. Instead, find them in + build/qtest.log. For packagers who are + building with an autobuilder, you can add the + option to + ./configure to restore the old behavior. + + + + + + + + + 2.3.1: December 28, 2011 + + + + + Fix thread-safety problem resulting from non-thread-safe use + of the PCRE library. + + + + + Made a few minor documentation fixes. + + + + + Add workaround for a bug that appears in some versions of + ghostscript to the test suite + + + + + Fix minor build issue for Visual C++ 2010. + + + + + + + 2.3.0: August 11, 2011 + + + + + Bug fix: when preserving existing encryption on encrypted + files with cleartext metadata, older qpdf versions would + generate password-protected files with no valid password. + This operation now works. This bug only affected files + created by copying existing encryption parameters; explicit + encryption with specification of cleartext metadata worked + before and continues to work. + + + + + Enhance QPDFWriter with a new + constructor that allows you to delay the specification of the + output file. When using this constructor, you may now call + QPDFWriter::setOutputFilename to specify + the output file, or you may use + QPDFWriter::setOutputMemory to cause + QPDFWriter to write the resulting PDF + file to a memory buffer. You may then use + QPDFWriter::getBuffer to retrieve the + memory buffer. + + + + + Add new API call QPDF::replaceObject for + replacing objects by object ID + + + + + Add new API call QPDF::swapObjects for + swapping two objects by object ID + + + + + Add QPDFObjectHandle::getDictAsMap and + QPDFObjectHandle::getArrayAsVector to + allow retrieval of dictionary objects as maps and array + objects as vectors. + + + + + Add functions qpdf_get_info_key and + qpdf_set_info_key to the C API for + manipulating string fields of the document's + /Info dictionary. + + + + + Add functions qpdf_init_write_memory, + qpdf_get_buffer_length, and + qpdf_get_buffer to the C API for writing + PDF files to a memory buffer instead of a file. + + + + + + + + + 2.2.4: June 25, 2011 + + + + + Fix installation and compilation issues; no functionality + changes. + + + + + + + 2.2.3: April 30, 2011 + + + + + Handle some damaged streams with incorrect characters + following the stream keyword. + + + + + Improve handling of inline images when normalizing content + streams. + + + + + Enhance error recovery to properly handle files that use + object 0 as a regular object, which is specifically disallowed + by the spec. + + + + + + + 2.2.2: October 4, 2010 + + + + + Add new function qpdf_read_memory + to the C API to call + QPDF::processMemoryFile. This was an + omission in qpdf 2.2.1. + + + + + + + 2.2.1: October 1, 2010 + + + + + Add new method QPDF::setOutputStreams + to replace std::cout and + std::cerr with other streams for generation + of diagnostic messages and error messages. This can be useful + for GUIs or other applications that want to capture any output + generated by the library to present to the user in some other + way. Note that QPDF does not write to + std::cout (or the specified output stream) + except where explicitly mentioned in + QPDF.hh, and that the only use of the + error stream is for warnings. Note also that output of + warnings is suppressed when + setSuppressWarnings(true) is called. + + + + + Add new method QPDF::processMemoryFile + for operating on PDF files that are loaded into memory rather + than in a file on disk. + + + + + Give a warning but otherwise ignore empty PDF objects by + treating them as null. Empty object are not permitted by the + PDF specification but have been known to appear in some actual + PDF files. + + + + + Handle inline image filter abbreviations when the appear as + stream filter abbreviations. The PDF specification does not + allow use of stream filter abbreviations in this way, but + Adobe Reader and some other PDF readers accept them since they + sometimes appear incorrectly in actual PDF files. + + + + + Implement miscellaneous enhancements to + PointerHolder and + Buffer to support other changes. + + + + + + + 2.2.0: August 14, 2010 + + + + + Add new methods to QPDFObjectHandle + (newStream and + replaceStreamData for creating new + streams and replacing stream data. This makes it possible to + perform a wide range of operations that were not previously + possible. + + + + + Add new helper method in + QPDFObjectHandle + (addPageContents) for appending or + prepending new content streams to a page. This method makes + it possible to manipulate content streams without having to be + concerned whether a page's contents are a single stream or an + array of streams. + + + + + Add new method in QPDFObjectHandle: + replaceOrRemoveKey, which replaces a + dictionary key + with a given value unless the value is null, in which case it + removes the key instead. + + + + + Add new method in QPDFObjectHandle: + getRawStreamData, which returns the raw + (unfiltered) stream data into a buffer. This complements the + getStreamData method, which returns the + filtered (uncompressed) stream data and can only be used when + the stream's data is filterable. + + + + + Provide two new examples: + pdf-double-page-size and + pdf-invert-images that illustrate the newly + added interfaces. + + + + + Fix a memory leak that would cause loss of a few bytes for + every object involved in a cycle of object references. Thanks + to Jian Ma for calling my attention to the leak. + + + + + + + 2.1.5: April 25, 2010 + + + + + Remove restriction of file identifier strings to 16 bytes. + This unnecessary restriction was preventing qpdf from being + able to encrypt or decrypt files with identifier strings that + were not exactly 16 bytes long. The specification imposes no + such restriction. + + + + + + + 2.1.4: April 18, 2010 + + + + + Apply the same padding calculation fix from version 2.1.2 to + the main cross reference stream as well. + + + + + Since qpdf --check only performs limited + checks, clarify the output to make it clear that there still + may be errors that qpdf can't check. This should make it less + surprising to people when another PDF reader is unable to read + a file that qpdf thinks is okay. + + + + + + + 2.1.3: March 27, 2010 + + + + + Fix bug that could cause a failure when rewriting PDF files + that contain object streams with unreferenced objects that in + turn reference indirect scalars. + + + + + Don't complain about (invalid) AES streams that aren't a + multiple of 16 bytes. Instead, pad them before decrypting. + + + + + + + 2.1.2: January 24, 2010 + + + + + Fix bug in padding around first half cross reference stream in + linearized files. The bug could cause an assertion failure + when linearizing certain unlucky files. + + + + + + + 2.1.1: December 14, 2009 + + + + + No changes in functionality; insert missing include in an + internal library header file to support gcc 4.4, and update + test suite to ignore broken Adobe Reader installations. + + + + + + + 2.1: October 30, 2009 + + + + + This is the first version of qpdf to include Windows support. + On Windows, it is possible to build a DLL. Additionally, a + partial C-language API has been introduced, which makes it + possible to call qpdf functions from non-C++ environments. I + am very grateful to Zarko Gagic (http://delphi.about.com/) + for tirelessly testing numerous pre-release versions of this + DLL and providing many excellent suggestions on improving the + interface. + + + For programming to the C interface, please see the header file + qpdf/qpdf-c.h and the example + examples/pdf-linearize.c. + + + + + Zarko Gajic has written a Delphi wrapper for qpdf, which can + be downloaded from qpdf's download side. Zarko's Delphi + wrapper is released with the same licensing terms as qpdf + itself and comes with this disclaimer: “Delphi wrapper + unit qpdf.pas created by Zarko Gajic + (http://delphi.about.com/). + Use at your own risk and for whatever purpose you want. No + support is provided. Sample code is provided.” + + + + + Support has been added for AES encryption and crypt filters. + Although qpdf does not presently support files that use + PKI-based encryption, with the addition of AES and crypt + filters, qpdf is now be able to open most encrypted files + created with newer versions of Acrobat or other PDF creation + software. Note that I have not been able to get very many + files encrypted in this way, so it's possible there could + still be some cases that qpdf can't handle. Please report + them if you find them. + + + + + Many error messages have been improved to include more + information in hopes of making qpdf a more useful tool for PDF + experts to use in manually recovering damaged PDF files. + + + + + Attempt to avoid compressing metadata streams if possible. + This is consistent with other PDF creation applications. + + + + + Provide new command-line options for AES encrypt, cleartext + metadata, and setting the minimum and forced PDF versions of + output files. + + + + + Add additional methods to the QPDF + object for querying the document's permissions. Although qpdf + does not enforce these permissions, it does make them + available so that applications that use qpdf can enforce + permissions. + + + + + The option to qpdf + has been extended to include some additional information. + + + + + There have been a handful of non-compatible API changes. For + details, see . + + + + + + + 2.0.6: May 3, 2009 + + + + + Do not attempt to uncompress streams that have decode + parameters we don't recognize. Earlier versions of qpdf would + have rejected files with such streams. + + + + + + + 2.0.5: March 10, 2009 + + + + + Improve error handling in the LZW decoder, and fix a small + error introduced in the previous version with regard to + handling full tables. The LZW decoder has been more strongly + verified in this release. + + + + + + + 2.0.4: February 21, 2009 + + + + + Include proper support for LZW streams encoded without the + “early code change” flag. Special thanks to Atom + Smasher who reported the problem and provided an input file + compressed in this way, which I did not previously have. + + + + + Implement some improvements to file recovery logic. + + + + + + + 2.0.3: February 15, 2009 + + + + + Compile cleanly with gcc 4.4. + + + + + Handle strings encoded as UTF-16BE properly. + + + + + + + 2.0.2: June 30, 2008 + + + + + Update test suite to work properly with a + non-bash /bin/sh and + with Perl 5.10. No changes were made to the actual qpdf + source code itself for this release. + + + + + + + 2.0.1: May 6, 2008 + + + + + No changes in functionality or interface. This release + includes fixes to the source code so that qpdf compiles + properly and passes its test suite on a broader range of + platforms. See ChangeLog in the source + distribution for details. + + + + + + + 2.0: April 29, 2008 + + + + + First public release. + + + + + + + + + Upgrading from 2.0 to 2.1 + + Although, as a general rule, we like to avoid introducing + source-level incompatibilities in qpdf's interface, there were a + few non-compatible changes made in this version. A considerable + amount of source code that uses qpdf will probably compile without + any changes, but in some cases, you may have to update your code. + The changes are enumerated here. There are also some new + interfaces; for those, please refer to the header files. + + + + + QPDF's exception handling mechanism now uses + std::logic_error for internal errors and + std::runtime_error for runtime errors in + favor of the now removed QEXC classes used + in previous versions. The QEXC exception + classes predated the addition of the + <stdexcept> header file to the C++ + standard library. Most of the exceptions thrown by the qpdf + library itself are still of type QPDFExc + which is now derived from + std::runtime_error. Programs that caught + an instance of std::exception and + displayed it by calling the what() method + will not need to be changed. + + + + + The QPDFExc class now internally + represents various fields of the error condition and provides + interfaces for querying them. Among the fields is a numeric + error code that can help applications act differently on (a small + number of) different error conditions. See + QPDFExc.hh for details. + + + + + Warnings can be retrieved from qpdf as instances of + QPDFExc instead of strings. + + + + + The nested QPDF::EncryptionData class's + constructor takes an additional argument. This class is + primarily intended to be used by + QPDFWriter. There's not really anything + useful an end-user application could do with it. It probably + shouldn't really be part of the public interface to begin with. + Likewise, some of the methods for computing internal encryption + dictionary parameters have changed to support + /R=4 encryption. + + + + + The method QPDF::getUserPassword has been + removed since it didn't do what people would think it did. There + are now two new methods: + QPDF::getPaddedUserPassword and + QPDF::getTrimmedUserPassword. The first one + does what the old QPDF::getUserPassword + method used to do, which is to return the password with possible + binary padding as specified by the PDF specification. The second + one returns a human-readable password string. + + + + + The enumerated types that used to be nested in + QPDFWriter have moved to top-level + enumerated types and are now defined in the file + qpdf/Constants.h. This enables them to be + shared by both the C and C++ interfaces. + + + + + + Upgrading to 3.0 + + For the most part, the API for qpdf version 3.0 is backward + compatible with versions 2.1 and later. There are two exceptions: + + + + The method + QPDFObjectHandle::replaceStreamData that + uses a StreamDataProvider to provide the + stream data no longer takes a length + parameter. While it would have been easy enough to keep the + parameter for backward compatibility, in this case, the + parameter was removed since this provides the user an + opportunity to simplify the calling code. This method was + introduced in version 2.2. At the time, the + length parameter was required in order to + ensure that calls to the stream data provider returned the same + length for a specific stream every time they were invoked. In + particular, the linearization code depends on this. Instead, + qpdf 3.0 and newer check for that constraint explicitly. The + first time the stream data provider is called for a specific + stream, the actual length is saved, and subsequent calls are + required to return the same number of bytes. This means the + calling code no longer has to compute the length in advance, + which can be a significant simplification. If your code fails + to compile because of the extra argument and you don't want to + make other changes to your code, just omit the argument. + + + + + Many methods take long long instead of other + integer types. Most if not all existing code should compile + fine with this change since such parameters had always + previously been smaller types. This change was required to + support files larger than two gigabytes in size. + + + + + + diff --git a/manual/qpdf.1.in b/manual/qpdf.1.in new file mode 100644 index 0000000..3ecec56 --- /dev/null +++ b/manual/qpdf.1.in @@ -0,0 +1,19 @@ +\" This file is not processed by autoconf, but rather by build.mk in +\" the manual directory. +.TH QPDF "1" "April 2008" "qpdf version @PACKAGE_VERSION@" "User Commands" +.SH NAME +qpdf \- PDF transformation software +.SH SYNOPSIS +.B qpdf +[ \fIoptions \fR] \fIinfilename [ outfilename ]\fR +.SH DESCRIPTION +The qpdf program is used to convert one PDF file to another equivalent +PDF file.

This works even if\n\ +the owner password is not known.\n\ +\n\ +\n\ +Encryption Options\n\ +------------------\n\ +\n\ + --encrypt user-password owner-password key-length flags --\n\ +\n\ +Note that -- terminates parsing of encryption flags.\n\ +\n\ +Either or both of the user password and the owner password may be\n\ +empty strings.\n\ +\n\ +key-length may be 40 or 128\n\ +\n\ +Additional flags are dependent upon key length.\n\ +\n\ + If 40:\n\ +\n\ + --print=[yn] allow printing\n\ + --modify=[yn] allow document modification\n\ + --extract=[yn] allow text/graphic extraction\n\ + --annotate=[yn] allow comments and form fill-in and signing\n\ +\n\ + If 128:\n\ +\n\ + --accessibility=[yn] allow accessibility to visually impaired\n\ + --extract=[yn] allow other text/graphic extraction\n\ + --print=print-opt control printing access\n\ + --modify=modify-opt control modify access\n\ + --cleartext-metadata prevents encryption of metadata\n\ + --use-aes=[yn] indicates whether to use AES encryption\n\ + --force-V4 forces use of V=4 encryption handler\n\ +\n\ + print-opt may be:\n\ +\n\ + full allow full printing\n\ + low allow only low-resolution printing\n\ + none disallow printing\n\ +\n\ + modify-opt may be:\n\ +\n\ + all allow full document modification\n\ + annotate allow comment authoring and form operations\n\ + form allow form field fill-in and signing\n\ + assembly allow document assembly only\n\ + none allow no modifications\n\ +\n\ +The default for each permission option is to be fully permissive.\n\ +\n\ +Specifying cleartext-metadata forces the PDF version to at least 1.5.\n\ +Specifying use of AES forces the PDF version to at least 1.6. These\n\ +options are both off by default.\n\ +\n\ +The --force-V4 flag forces the V=4 encryption handler introduced in PDF 1.5\n\ +to be used even if not otherwise needed. This option is primarily useful\n\ +for testing qpdf and has no other practical use.\n\ +\n\ +\n\ +Page Selection Options\n\ +----------------------\n\ +\n\ +These options allow pages to be selected from one or more PDF files.\n\ +Whatever file is given as the primary input file is used as the\n\ +starting point, but its pages are replaced with pages as specified.\n\ +\n\ +--pages file [ --password=password ] page-range ... --\n\ +\n\ +For each file that pages should be taken from, specify the file, a\n\ +password needed to open the file (if any), and a page range. The\n\ +password needs to be given only once per file. If any of the input\n\ +files are the same as the primary input file or the file used to copy\n\ +encryption parameters (if specified), you do not need to repeat the\n\ +password here. The same file can be repeated multiple times. All\n\ +non-page data (info, outlines, page numbers, etc. are taken from the\n\ +primary input file. To discard this, use --empty as the primary\n\ +input.\n\ +\n\ +The page range is a set of numbers separated by commas, ranges of\n\ +numbers separated dashes, or combinations of those. The character\n\ +\"z\" represents the last page. Pages can appear in any order. Ranges\n\ +can appear with a high number followed by a low number, which causes the\n\ +pages to appear in reverse. Repeating a number will cause an error, but\n\ +the manual discusses a workaround should you really want to include the\n\ +same page twice.\n\ +\n\ +See the manual for examples and a discussion of additional subtleties.\n\ +\n\ +\n\ +Advanced Transformation Options\n\ +-------------------------------\n\ +\n\ +These transformation options control fine points of how qpdf creates\n\ +the output file. Mostly these are of use only to people who are very\n\ +familiar with the PDF file format or who are PDF developers.\n\ +\n\ +--stream-data=option controls transformation of stream data (below)\n\ +--normalize-content=[yn] enables or disables normalization of content streams\n\ +--suppress-recovery prevents qpdf from attempting to recover damaged files\n\ +--object-streams=mode controls handing of object streams\n\ +--ignore-xref-streams tells qpdf to ignore any cross-reference streams\n\ +--qdf turns on \"QDF mode\" (below)\n\ +--min-version=version sets the minimum PDF version of the output file\n\ +--force-version=version forces this to be the PDF version of the output file\n\ +\n\ +Values for stream data options:\n\ +\n\ + compress recompress stream data when possible (default)\n\ + preserve leave all stream data as is\n\ + uncompress uncompress stream data when possible\n\ +\n\ +Values for object stream mode:\n\ +\n\ + preserve preserve original object streams (default)\n\ + disable don't write any object streams\n\ + generate use object streams wherever possible\n\ +\n\ +In qdf mode, by default, content normalization is turned on, and the\n\ +stream data mode is set to uncompress.\n\ +\n\ +Setting the minimum PDF version of the output file may raise the version\n\ +but will never lower it. Forcing the PDF version of the output file may\n\ +set the PDF version to a lower value than actually allowed by the file's\n\ +contents. You should only do this if you have no other possible way to\n\ +open the file or if you know that the file definitely doesn't include\n\ +features not supported later versions.\n\ +\n\ +Testing, Inspection, and Debugging Options\n\ +------------------------------------------\n\ +\n\ +These options can be useful for digging into PDF files or for use in\n\ +automated test suites for software that uses the qpdf library.\n\ +\n\ +--static-id generate static /ID: FOR TESTING ONLY!\n\ +--static-aes-iv use a static initialization vector for AES-CBC\n\ + This is option is not secure! FOR TESTING ONLY!\n\ +--no-original-object-ids suppress original object ID comments in qdf mode\n\ +--show-encryption quickly show encryption parameters\n\ +--check-linearization check file integrity and linearization status\n\ +--show-linearization check and show all linearization data\n\ +--show-xref show the contents of the cross-reference table\n\ +--show-object=obj[,gen] show the contents of the given object\n\ + --raw-stream-data show raw stream data instead of object contents\n\ + --filtered-stream-data show filtered stream data instead of object contents\n\ +--show-pages shows the object/generation number for each page\n\ + --with-images also shows the object IDs for images on each page\n\ +--check check file structure + encryption, linearization\n\ +\n\ +The --raw-stream-data and --filtered-stream-data options are ignored\n\ +unless --show-object is given. Either of these options will cause the\n\ +stream data to be written to standard output.\n\ +\n\ +If --filtered-stream-data is given and --normalize-content=y is also\n\ +given, qpdf will attempt to normalize the stream data as if it is a\n\ +page content stream. This attempt will be made even if it is not a\n\ +page content stream, in which case it will produce unusable results.\n\ +\n\ +Ordinarily, qpdf exits with a status of 0 on success or a status of 2\n\ +if any errors occurred. In --check mode, if there were warnings but not\n\ +errors, qpdf exits with a status of 3.\n\ +\n"; + +void usage(std::string const& msg) +{ + std::cerr + << std::endl + << whoami << ": " << msg << std::endl + << std::endl + << "Usage: " << whoami << " [options] infile outfile" << std::endl + << "For detailed help, run " << whoami << " --help" << std::endl + << std::endl; + exit(EXIT_ERROR); +} + +static std::string show_bool(bool v) +{ + return v ?
