This ensured that the path was closed (in both + Character Space and Device Space). But if the final element was a + curve and if the final hintmap was different enough from the initial + one, then the curve was visibly distorted. + + The first part of the fix is to draw the final curve using the final + hintmap as specified by the charstring. This corrects the + distortion but does not ensure closing in Device Space. It may + require the rasterizer to automatically generate an extra closing + line. Depending on the hintmap differences, this line could be from + zero to a couple pixels in length. + + The second part of the fix covers the case where the charstring + subpath is closed with an explicit line. We now modify that line's + end point to avoid the distortion. + + Some glyphs in the bug report font (TexGyreHeros-Regular) that show + the change are: + + 25ppem S (98) + 24ppem eight (52) + 25.5ppem p (85) + + Curves at the *end* of a subpath are no longer distorted. However, + some of these glyphs have bad hint substitutions in the middle of a + subpath, and these are not affected. + + The patch has been tested with a set of 106 fonts that shipped with + Adobe Creative Suite 4, together with 756 Open Source CFF fonts from + Google Fonts. There are 1.5 million glyphs, of which some 20k are + changed with the fix.

The default is value 2. + + At run time, you can select the subpixel hinting mode with the + `interpreter-version' property (provided you have compiled in + the corresponding hinting mode); see `ftttdrv.h' for more. + + - Support for the following scripts has been added to the + auto-hinter. + + Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi, + Malayalam, Sinhala, Tamil + + + II. MISCELLANEOUS + + - Type 42 fonts as created by LilyPond are now supported. + + - Minor rendering improvments in the auto-hinter. + + - For experimental reasons, the old CFF engine now supports all + CFF operators except `random', including the deprecated Multiple + Masters instructions. This allows the display of fonts like + `ITCGaramondMM-It.otf' (without font variations, though). + + - Another round of fixes to improve handling of invalid fonts. + + - The `ftgrid' demo program now displays the rendered pixels also; + this can be switched off with the `b' key. Selection of various + LCD filtering modes can be done with the `L' key. + + - The demo programs have been extended to allow selection of all + available TrueType bytecode engines. + + - A very early beta version of a new, Qt based demo program called + `ftinspect' is part of the source code bundle; it will + eventually supersede the other demo programs. Currently, you + have to compile it manually with `qmake; make'; note that many + features are still missing. + + +====================================================================== + +CHANGES BETWEEN 2.6.2 and 2.6.3 + + I. IMPORTANT CHANGES + + - Khmer, Myanmar, Bengali, and Kannada script support has been + added to the auto-hinter. + + + II. MISCELLANEOUS + + - Better support of Indic scripts like Devanagari by using a + top-to-bottom hinting flow. + + - All FreeType macros starting with two underscores have been + renamed to avoid a violation of both the C and C++ standards. + Example: Header macros of the form `__FOO_H__' are now called + `FOO_H_'. In most cases, this should be completely transparent + to the user. The exception to this is `__FTERRORS_H__', which + must be sometimes undefined by the user to get FreeType error + strings: Both this form and the new `FTERRORS_H_' macro are + accepted for backwards compatibility. + + - Minor improvements mainly to the Type 1 driver. + + - The new CFF engine now supports all Type 2 operators except + `random'. + + - The macro `_STANDALONE_', used for compiling the B/W and smooth + rasterizers as stand-alone modules, has been renamed to + `STANDALONE_', since macro names starting with an underscore and + followed by an uppercase letter are reserved in both C and C++. + + - Function `FT_Library_SetLcdFilterWeights' now also activates + custom LCD filter weights (instead of just adjusting them). + + - Support for `unpatented hinting' has been completely removed: + Consequently, the two functions `FT_Face_CheckTrueTypePatents' + and `FT_Face_SetUnpatentedHinting' now return always false, + doing nothing. + + - The `ftgamma' demo program has been modernized; the gamma grid + display has been moved from `ftview' to this program. + + - In `ftview', it is now possible to cycle through the available + LCD filtering modes. + + +====================================================================== + +CHANGES BETWEEN 2.6.1 and 2.6.2 + + I. IMPORTANT CHANGES + + - The auto-hinter now supports stem darkening, to be controlled by + the new `no-stem-darkening' and `darkening-parameters' + properties. This is an experimental feature contributed by + Nikolaus Waxweiler, and the interface might change in a future + release. + + - By default, stem darkening is now switched off (for both the CFF + engine and the auto-hinter). The main reason is that you need + linear alpha blending and gamma correction to get correct + rendering results, and the latter is not yet available in most + freely available rendering stacks like X11. Applying stem + darkening without proper gamma correction leads to far too dark + rendering results. + + - The meaning of `FT_RENDER_MODE_LIGHT' has been slightly + modified. It now essentially means `no hinting along the + horizontal axis'; in particular, no change of glyph advance + widths. Consequently, the auto-hinter is used for all scalable + font formats except for CFF. It is planned that other + font-specific rendering engines (TrueType, Type 1) will follow. + + + II. MISCELLANEOUS + + - The default LCD filter has been changed to be normalized and + color-balanced. + + - For better compatibility with FontConfig, function + `FT_Library_SetLcdFilter' accepts a new enumeration value + `FT_LCD_FILTER_LEGACY1' (which has the same meaning as + `FT_LCD_FILTER_LEGACY'). + + - A large number of bugs have been detected by using the libFuzzer + framework, which should further improve handling of invalid + fonts. Thanks again to Kostya Serebryany and Bungeman! + + - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES', a new configuration + option, controls the maximum number of executed opcodes within a + bytecode program. You don't want to change this except for very + special situations (e.g., making a library fuzzer spend less + time to handle broken fonts). + + - The smooth renderer has been made faster. + + - The `ftstring' demo program now supports sub-pixel rendering; + use key `l' to cycle through the LCD modes. + + - The `ftstring' demo program now supports colour rendering; use + the `space' key to cycle through various colour combinations. + + - The graphical demo programs now use a default gamma value of 1.8 + (instead of 1.2). + + +====================================================================== + +CHANGES BETWEEN 2.6 and 2.6.1 + + I. IMPORTANT BUG FIXES + + - It turned out that for CFFs only the advance widths should be + taken from the `htmx' table, not the side bearings. This bug, + introduced in version 2.6.0, makes it necessary to upgrade if + you are using CFFs; otherwise, you get cropped glyphs with GUI + interfaces like GTK or Qt. + + - Accessing Type 42 fonts returned incorrect results if the glyph + order of the embedded TrueType font differs from the glyph order + of the Type 42 charstrings table. + + + II. IMPORTANT CHANGES + + - The header file layout has been changed (again), moving all + header files except `ft2build.h' into a subdirectory tree. + + Doing so reduces the possibility of header file name clashes + (e.g., FTGL's `FTGlyph.h' with FreeType's `ftglyph.h') on case + insensitive file systems like Mac OS X or Windows. + + Applications that use (a) the `freetype-config' script or + FreeType's `freetype2.pc' file for pkg-config to get the include + directory for the compiler, and (b) the documented way for + header inclusion like + + #include <ft2build.h> + #include FT_FREETYPE_H + ... + + don't need any change to the source code. + + - Simple access to named instances in GX variation fonts is now + available (in addition to the previous method via FreeType's MM + interface). In the `FT_Face' structure, bits 16-30 of the + `face_index' field hold the current named instance index for the + given face index, and bits 16-30 of `style_flags' contain the + number of instances for the given face index. `FT_Open_Face' + and friends also understand the extended bits of the face index + parameter. + + You need to enable TT_CONFIG_OPTION_GX_VAR_SUPPORT for this new + feature. Otherwise, bits 16-30 of the two fields are zero (or + are ignored). + + - Lao script support has been added to the auto-hinter. + + + III. MISCELLANEOUS + + - The auto-hinter's Arabic script support has been enhanced. + + - Superscript-like and subscript-like glyphs as used by various + phonetic alphabets like the IPA are now better supported by the + auto-hinter. + + - The TrueType bytecode interpreter now runs slightly faster. + + - Improved support for builds with cmake. + + - The function `FT_CeilFix' now always rounds towards plus + infinity. + + - The function `FT_FloorFix' now always rounds towards minus + infinity. + + - A new load flag `FT_LOAD_COMPUTE_METRICS' has been added; it + makes FreeType ignore pre-computed metrics, as needed by font + validating or font editing programs. Right now, only the + TrueType module supports it to ignore data from the `hdmx' + table. + + - Another round of bug fixes to better handle broken fonts, found + by Kostya Serebryany <kcc@google.com>. + + +====================================================================== + +CHANGES BETWEEN 2.5.5 and 2.6 + + I. IMPORTANT CHANGES + + - Behdad Esfahbod contributed code for improved thread-safety, + which results in the following model. + + * An `FT_Face' object can only be safely used from one thread at + a time. + + * An `FT_Library' object can now be used without modification + from multiple threads at the same time. + + * `FT_Face' creation and destruction with the same `FT_Library' + object can only be done from one thread at a time. + + One can use a single `FT_Library' object across threads as long + as a mutex lock is used around `FT_New_Face' and `FT_Done_Face'. + Any calls to `FT_Load_Glyph' and similar API are safe and do not + need the lock to be held as long as the same `FT_Face' is not + used from multiple threads at the same time. + + - Thai script support has been added to the auto-hinter. + + - Arabic script support has been added to the auto-hinter. + + - Following OpenType version 1.7, advance widths and side bearing + values in CFFs (wrapped in an SFNT structure) are now always + taken from the `hmtx' table. + + - Following OpenType version 1.7, the PostScript font name of a + CFF font (wrapped in an SFNT structure) is now always taken from + the `name' table. This is also true for OpenType Collections + (i.e., TTCs using CFFs subfonts instead of TTFs), where it may + have a significant difference. + + - Fonts natively hinted for ClearType are now supported, properly + handling selector index 3 of the INSTCTRL bytecode instruction. + + - Major improvements to the GX TrueType variation font handling. + + + II. MISCELLANEOUS + + - A new auto-hinter property `warping' can switch on and off the + warping code if this experimental feature is compiled in (by + defining the AF_CONFIG_OPTION_USE_WARPER configuration option; + by default this option is now enabled but warping is switched + off). + + The AF_CONFIG_OPTION_USE_WARPER option itself is an old feature, + available since 2006. Warping only works in `light' + auto-hinting mode. The idea of the code is to slightly scale + and shift a glyph along the non-hinted dimension (which is + usually the horizontal axis) so that as much of its segments are + aligned (more or less) to the grid. To find out a glyph's + optimal scaling and shifting value, various parameter + combinations are tried and scored. + + See file `ftautoh.h' for more; the demo programs `ftdiff', + `ftview', and `ftgrid' can toggle warping with key `w'. + + - Some fields in the `FTC_ImageTypeRec' structure have been + changed from signed to unsigned type, which better reflects the + actual usage. It is also an additional means to protect against + malformed input. + + This change doesn't break the ABI; however, it might cause + compiler warnings. + + - Function `FT_Bitmap_New' has been renamed to `FT_Bitmap_Init', + since this name better reflects its function. For backwards + compatibility, the old function name is still available. + + - Function `FT_Get_X11_Font_Format' has been renamed to + `FT_Get_Font_Format', since this name better reflects its + function. For backwards compatibility, the old function name is + still available. + + Additionally, the header file macro for this function has been + renamed to `FT_FONT_FORMATS_H' (the old name `FT_XFREE86_H' is + retained for backwards compatibility). + + - Various improvements to the `ftgrid' demo program. + + . It can now display GX and MM fonts while interactively + manipulating the axes (with keys F2, F3, and F4). + + . Anti-aliasing rendering modes can now be selected (with keys + F5 and F6). + + . The display of point numbers can be toggled with key `D'. + + - Various improvements to the `ftdump' demo program. + + . It now displays information on MM and GX variation axes. + + . New command line option `-u' makes it output data in utf-8 + encoding. + + - The `ftmulti' demo program can now handle up to six MM or GX + axes. + + +====================================================================== + CHANGES BETWEEN 2.5.4 and 2.5.5 I.

The side-effect is that glyphs ‘thin out’. Mac OS X and Adobe's proprietary font rendering library implement a counter-measure: stem darkening at smaller sizes where shades of gray dominate. By emboldening a glyph slightly in relation to its pixel size, individual pixels get higher coverage of filled-in outlines and are therefore ‘blacker’. This counteracts the ‘thinning out’ of glyphs, making text remain readable at smaller sizes.

Total consistency with the CFF driver is currently not achieved because the emboldening method differs and glyphs must be scaled down on the Y-axis to keep outline points inside their precomputed blue zones.

If a pixel is completely covered by a filled-in outline, the bitmap contains 0xFF at that pixel, meaning that 0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100% black (or 0% bright).

On the low-DPI screens, however, the situation is different. The pixels are too large for most of the details of a glyph and shades of gray are the norm rather than the exception.</p> +<p>This is relevant because all our screens have a second problem: they are not linear. 1 + 1 is not 2. Twice the value does not result in twice the brightness. When a pixel is only 50% covered, the coverage map says 50% black, and this translates to a pixel value of 128 when you use 8 bits per channel (0-255). However, this does not translate to 50% brightness for that pixel on our sRGB and gamma 2.2 screens. Due to their non-linearity, they dwell longer in the darks and only a pixel value of about 186 results in 50% brightness – 128 ends up too dark on both bright and dark backgrounds. The net result is that dark text looks burnt-out, pixely and blotchy on bright background, bright text too frail on dark backgrounds, and colored text on colored background (for example, red on green) seems to have dark halos or ‘dirt’ around it. The situation is especially ugly for diagonal stems like in ‘w’ glyph shapes where the quality of FreeType's anti-aliasing depends on the correct display of grays. On high-DPI screens where smaller, fully black pixels reign supreme, this doesn't matter, but on our low-DPI screens with all the gray shades, it does. 0% and 100% brightness are the same things in linear and non-linear space, just all the shades in-between aren't.</p> +<p>The blending function for placing text over a background is</p> +<pre class="colored"> + dst = alpha * src + (1 - alpha) * dst , +</pre> +<p>which is known as the OVER operator.</p> +<p>To correctly composite an antialiased pixel of a glyph onto a surface,</p> +<p>1. take the foreground and background colors (e.g., in sRGB space) and apply gamma to get them in a linear space,</p> +<p>2. use OVER to blend the two linear colors using the glyph pixel as the alpha value (remember, the glyph bitmap is an alpha coverage bitmap), and</p> +<p>3. apply inverse gamma to the blended pixel and write it back to the image.</p> +<p>Internal testing at Adobe found that a target inverse gamma of 1.8 for step 3 gives good results across a wide range of displays with an sRGB gamma curve or a similar one.</p> +<p>This process can cost performance.

This makes the screen display as close as it can be to the result one would get with infinite resolution, while preserving what is considered the key characteristics of each glyph. Note that the distances between unhinted and grid-fitted positions at small sizes are comparable to kerning values and thus would be noticeable (and distracting) while reading if hinting were applied.</p> <p>One of the reasons to not hint horizontally is antialiasing for LCD screens: The pixel geometry of modern displays supplies three vertical sub-pixels as the eye moves horizontally across each visible pixel. On devices where we can be certain this characteristic is present a rasterizer can take advantage of the sub-pixels to add increments of weight. In Western writing systems this turns out to be the more critical direction anyway; the weights and spacing of vertical stems (see above) are central to Armenian, Cyrillic, Greek, and Latin type designs. Even when the rasterizer uses greyscale antialiasing instead of color (a necessary compromise when one doesn't know the screen characteristics), the unhinted vertical features preserve the design's weight and spacing much better than aliased type would.</p> -<p>2) Aligment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of 1/3 pixels) is less of a problem.</p> +<p>2) Alignment in the vertical direction: Weights and spacing along the y axis are less critical; what is much more important is the visual alignment of related features (like cap-height and x-height). The sense of alignment for these is enhanced by the sharpness of grid-fit edges, while the cruder vertical resolution (full pixels instead of 1/3 pixels) is less of a problem.</p> <p>On the technical side, horizontal alignment zones for ascender, x-height, and other important height values (traditionally called ‘blue zones’) as defined in the font are positioned independently, each being rounded to the nearest pixel edge, taking care of overshoot suppression at small sizes, stem darkening, and scaling.</p> <p>Hstems (this is, hint values defined in the font to help align horizontal features) that fall within a blue zone are said to be ‘captured’ and are aligned to that zone. Uncaptured stems are moved in one of four ways, top edge up or down, bottom edge up or down.

Since these subpixels are color pixels, using them unfiltered creates severe color fringes. Use the <a href="ft2-lcd_filtering.html#FT_Library_SetLcdFilter">FT_Library_SetLcdFilter</a> API to specify a low-pass filter, which is then applied to subpixel-rendered bitmaps generated through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>. The filter sacrifices some of the higher resolution to reduce color fringes, making the glyph image slightly blurrier.

It is possible to go above or under this target sum, however: going under means tossing out contrast, going over means invoking clamping and thereby non-linearities that increase contrast somewhat at the expense of greater distortion and color-fringing. Contrast is better enhanced through stem darkening.</p> +<p>2) It should be color-balanced, meaning a filter ‘{ a, b, c, b, a }’ where a + b = c. It distributes the computed coverage for one subpixel to all subpixels equally, sacrificing some won resolution but drastically reducing color-fringing. Positioning improvements remain! Note that color-fringing can only really be minimized when using a color-balanced filter and alpha-blending the glyph onto a surface in linear space; see <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>.</p> +<p>Regarding the form, a filter can be a ‘boxy’ filter or a ‘beveled’ filter. Boxy filters are sharper but are less forgiving of non-ideal gamma curves of a screen (viewing angles!), beveled filters are fuzzier but more tolerant.</p> +<p>Examples:</p> +<p>- [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor normalized.</p> +<p>- [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not normalized.</p> +<p>- [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not balanced.</p> +<p>- [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not balanced.</p> +<p>- [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost balanced.</p> +<p>- [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost balanced.</p> +<p>The filter affects glyph bitmaps rendered through <a href="ft2-base_interface.html#FT_Render_Glyph">FT_Render_Glyph</a>, <a href="ft2-base_interface.html#FT_Load_Glyph">FT_Load_Glyph</a>, and <a href="ft2-base_interface.html#FT_Load_Char">FT_Load_Char</a>.

For example, for <a href="ft2-base_interface.html#FT_Render_Mode">FT_RENDER_MODE_LCD</a>, the filter adds 3 subpixels to the left, and 3 subpixels to the right. The bitmap offset values are adjusted accordingly, so clients shouldn't need to modify their layout and glyph positioning code when enabling the filter.</p> +<p>It is important to understand that linear alpha blending and gamma correction is critical for correctly rendering glyphs onto surfaces without artifacts and even more critical when subpixel rendering is involved.</p> +<p>Each of the 3 alpha values (subpixels) is independently used to blend one color channel. That is, red alpha blends the red channel of the text color with the red channel of the background pixel. The distribution of density values by the color-balanced filter assumes alpha blending is done in linear space; only then color artifacts cancel out.</p> <div class="section"> <h3 id="FT_LcdFilter">FT_LcdFilter</h3> -<p>Defined in FT_LCD_FILTER_H (ftlcdfil.h).</p> +<p>Defined in FT_LCD_FILTER_H (freetype/ftlcdfil.h).</p> <pre> <span class="keyword">typedef</span> <span class="keyword">enum</span> FT_LcdFilter_ { <a href="ft2-lcd_filtering.html#FT_LCD_FILTER_NONE">FT_LCD_FILTER_NONE</a> = 0, <a href="ft2-lcd_filtering.html#FT_LCD_FILTER_DEFAULT">FT_LCD_FILTER_DEFAULT</a> = 1, <a href="ft2-lcd_filtering.html#FT_LCD_FILTER_LIGHT">FT_LCD_FILTER_LIGHT</a> = 2, + <a href="ft2-lcd_filtering.html#FT_LCD_FILTER_LEGACY1">FT_LCD_FILTER_LEGACY1</a> = 3, <a href="ft2-lcd_filtering.html#FT_LCD_FILTER_LEGACY">FT_LCD_FILTER_LEGACY</a> = 16, FT_LCD_FILTER_MAX /* do not remove */ @@ -152,25 +154,30 @@ </td></tr> <tr><td class="val" id="FT_LCD_FILTER_DEFAULT">FT_LCD_FILTER_DEFAULT</td><td class="desc"> <p>The default filter reduces color fringes considerably, at the cost of a slight blurriness in the output.</p> +<p>It is a beveled, normalized, and color-balanced five-tap filter that is more forgiving to screens with non-ideal gamma curves and viewing angles.

Microsoft's GDI interface supported hinting of the right-side bearing point, such that the advance width could be non-linear. Most often this was done to achieve some level of glyph symmetry. To enable reasonable performance (e.g., not having to run hinting on all glyphs just to get the widths) there was a bit in the head table indicating if the side bearing was hinted, and additional tables, ‘hdmx’ and ‘LTSH’, to cache hinting widths across multiple sizes and device aspect ratios.</p> +<p><i>Font</i> <i>Smoothing</i></p> +<p>Microsoft's GDI implementation of anti-aliasing. Not traditional anti-aliasing as the outlines were hinted before the sampling. The widths matched the bi-level rendering.</p> +<p><i>ClearType</i> <i>Rendering</i></p> +<p>Technique that uses physical subpixels to improve rendering on LCD (and other) displays. Because of the higher resolution, many methods of improving symmetry in glyphs through hinting the right-side bearing were no longer necessary. This lead to what GDI calls ‘natural widths’ ClearType, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec21">http://www.beatstamm.com/typography/RTRCh4.htm#Sec21</a>. Since hinting has extra resolution, most non-linearity went away, but it is still possible for hints to change the advance widths in this mode.</p> +<p><i>ClearType</i> <i>Compatible</i> <i>Widths</i></p> +<p>One of the earliest challenges with ClearType was allowing the implementation in GDI to be selected without requiring all UI and documents to reflow. To address this, a compatible method of rendering ClearType was added where the font hints are executed once to determine the width in bi-level rendering, and then re-run in ClearType, with the difference in widths being absorbed in the font hints for ClearType (mostly in the white space of hints); see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec20">http://www.beatstamm.com/typography/RTRCh4.htm#Sec20</a>. Somewhat by definition, compatible width ClearType allows for non-linear widths, but only when the bi-level version has non-linear widths.</p> +<p><i>ClearType</i> <i>Subpixel</i> <i>Positioning</i></p> +<p>One of the nice benefits of ClearType is the ability to more crisply display fractional widths; unfortunately, the GDI model of integer bitmaps did not support this. However, the WPF and Direct Write frameworks do support fractional widths. DWrite calls this ‘natural mode’, not to be confused with GDI's ‘natural widths’. Subpixel positioning, in the current implementation of Direct Write, unfortunately does not support hinted advance widths, see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec22">http://www.beatstamm.com/typography/RTRCh4.htm#Sec22</a>. Note that the TrueType interpreter fully allows the advance width to be adjusted in this mode, just the DWrite client will ignore those changes.</p> +<p><i>ClearType</i> <i>Backwards</i> <i>Compatibility</i></p> +<p>This is a set of exceptions made in the TrueType interpreter to minimize hinting techniques that were problematic with the extra resolution of ClearType; see <a href="http://www.beatstamm.com/typography/RTRCh4.htm#Sec1">http://www.beatstamm.com/typography/RTRCh4.htm#Sec1</a> and <a href="http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx">http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx</a>. This technique is not to be confused with ClearType compatible widths. ClearType backwards compatibility has no direct impact on changing advance widths, but there might be an indirect impact on disabling some deltas. This could be worked around in backwards compatibility mode.</p> +<p><i>Native</i> <i>ClearType</i> <i>Mode</i></p> +<p>(Not to be confused with ‘natural widths’.)

Another name for v1.6's grayscale rendering is ‘font smoothing’, and ‘Color ClearType’ is sometimes also called ‘DWrite ClearType’. To differentiate between today's Color ClearType and the earlier ClearType variant with B/W rendering along the vertical axis, the latter is sometimes called ‘GDI ClearType’.</p> +<p>‘Normal’ and ‘high’ sampling describe the (virtual) resolution to access the rasterized outline after the hinting process. ‘Normal’ means 1 sample per grid line (i.e., B/W). In the current Microsoft implementation, ‘high’ means an extra virtual resolution of 16x16 (or 16x1) grid lines per pixel for bytecode instructions like ‘MIRP’. After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid lines for color filtering if Color ClearType is activated.</p> +<p>Note that ‘Gray ClearType’ is essentially the same as v1.6's grayscale rendering. However, the GETINFO instruction handles it differently: v1.6 returns bit 12 (hinting for grayscale), while v2.1 returns bits 13 (hinting for ClearType), 18 (symmetrical smoothing), and 19 (Gray ClearType). Also, this mode respects bits 2 and 3 for the version 1 gasp table exclusively (like Color ClearType), while v1.6 only respects the values of version 0 (bits 0 and 1).</p> +<p>Keep in mind that the features of the above interpreter versions might not map exactly to FreeType features or behavior because it is a fundamentally different library with different internals.</p> <hr> <table class="index-toc-link"><tr><td class="left">[<a href="ft2-index.html">Index</a>]</td><td class="middle">[<a href="#">Top</a>]</td><td class="right">[<a href="ft2-toc.html">TOC</a>]</td></tr></table></div> diff --git a/docs/reference/ft2-type1_tables.html b/docs/reference/ft2-type1_tables.html index 71355a9..2129c07 100644 --- a/docs/reference/ft2-type1_tables.html +++ b/docs/reference/ft2-type1_tables.html @@ -3,7 +3,7 @@ <html> <head> <meta http-equiv="Content-Type" content="text/html;

Microsoft's GDI interface + * supported hinting of the right-side bearing point, such that the + * advance width could be non-linear. Most often this was done to + * achieve some level of glyph symmetry. To enable reasonable + * performance (e.g., not having to run hinting on all glyphs just to + * get the widths) there was a bit in the head table indicating if the + * side bearing was hinted, and additional tables, `hdmx' and `LTSH', to + * cache hinting widths across multiple sizes and device aspect ratios. + * + * _Font_ _Smoothing_ + * + * Microsoft's GDI implementation of anti-aliasing. Not traditional + * anti-aliasing as the outlines were hinted before the sampling. The + * widths matched the bi-level rendering. + * + * _ClearType_ _Rendering_ + * + * Technique that uses physical subpixels to improve rendering on LCD + * (and other) displays. Because of the higher resolution, many methods + * of improving symmetry in glyphs through hinting the right-side + * bearing were no longer necessary. This lead to what GDI calls + * `natural widths' ClearType, see + * http://www.beatstamm.com/typography/RTRCh4.htm#Sec21. Since hinting + * has extra resolution, most non-linearity went away, but it is still + * possible for hints to change the advance widths in this mode. + * + * _ClearType_ _Compatible_ _Widths_ + * + * One of the earliest challenges with ClearType was allowing the + * implementation in GDI to be selected without requiring all UI and + * documents to reflow. To address this, a compatible method of + * rendering ClearType was added where the font hints are executed once + * to determine the width in bi-level rendering, and then re-run in + * ClearType, with the difference in widths being absorbed in the font + * hints for ClearType (mostly in the white space of hints); see + * http://www.beatstamm.com/typography/RTRCh4.htm#Sec20. Somewhat by + * definition, compatible width ClearType allows for non-linear widths, + * but only when the bi-level version has non-linear widths. + * + * _ClearType_ _Subpixel_ _Positioning_ + * + * One of the nice benefits of ClearType is the ability to more crisply + * display fractional widths; unfortunately, the GDI model of integer + * bitmaps did not support this. However, the WPF and Direct Write + * frameworks do support fractional widths. DWrite calls this `natural + * mode', not to be confused with GDI's `natural widths'. Subpixel + * positioning, in the current implementation of Direct Write, + * unfortunately does not support hinted advance widths, see + * http://www.beatstamm.com/typography/RTRCh4.htm#Sec22. Note that the + * TrueType interpreter fully allows the advance width to be adjusted in + * this mode, just the DWrite client will ignore those changes. + * + * _ClearType_ _Backwards_ _Compatibility_ + * + * This is a set of exceptions made in the TrueType interpreter to + * minimize hinting techniques that were problematic with the extra + * resolution of ClearType; see + * http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and + * http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx. + * This technique is not to be confused with ClearType compatible + * widths.

This could be worked around in backwards + * compatibility mode. + * + * _Native_ _ClearType_ _Mode_ + * + * (Not to be confused with `natural widths'.)

When ClearType was introduced, most + * fonts were not ready. Microsoft decided to implement a backwards + * compatibility mode that employed several simple to complicated + * assumptions and tricks that modified the interpretation of the + * bytecode contained in these fonts to make them look ClearType-y + * somehow. Most (web)fonts that were released since then have come to + * rely on these hacks to render correctly, even some of Microsoft's + * flagship ClearType fonts (Calibri, Cambria, Segoe UI). + * + * The minimal subpixel hinting code (interpreter version 40) employs a + * small list of font-agnostic hacks to bludgeon non-native-ClearType + * fonts (except tricky ones[1]) into submission. It will not try to + * toggle hacks for specific fonts for performance and complexity + * reasons. The focus is on modern (web)fonts rather than legacy fonts + * that were made for black-and-white rendering. + * + * Major hacks + * + * - Any point movement on the x axis is ignored (cf. `Direct_Move' and + * `Direct_Move_X'). This has the smallest code footprint and single + * biggest effect. The ClearType way to increase resolution is + * supersampling the x axis, the FreeType way is ignoring instructions + * on the x axis, which gives the same result in the majority of + * cases. + * + * - Points are not moved post-IUP (neither on the x nor on the y axis), + * except the x component of diagonal moves post-IUP (cf. + * `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point'). Post-IUP + * changes are commonly used to `fix' pixel patterns which has little + * use outside monochrome rendering. + * + * - SHPIX and DELTAP don't execute unless moving a composite on the + * y axis or moving a previously y touched point. SHPIX additionally + * denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP'). + * Both instructions are commonly used to `fix' pixel patterns for + * monochrome or Windows's GDI rendering but make little sense for + * FreeType rendering. Both can distort the outline. See [2] for + * details. + * + * - The hdmx table and modifications to phantom points are ignored. + * Bearings and advance widths remain unchanged (except rounding them + * outside the interpreter!), cf. `compute_glyph_metrics' and + * `TT_Hint_Glyph'. Letting non-native-ClearType fonts modify spacing + * might mess up spacing. + * + * Minor hacks + * + * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP. This + * prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at + * various sizes. + * + * (Post-IUP is the state after both IUP[x] and IUP[y] have been + * executed.) + * + * The best results are achieved for fonts that were from the outset + * designed with ClearType in mind, meaning they leave the x axis mostly + * alone and don't mess with the `final' outline to produce more + * pleasing pixel patterns. The harder the designer tried to produce + * very specific patterns (`superhinting') for pre-ClearType-displays, + * the worse the results. + * + * Microsoft defines a way to turn off backwards compatibility and + * interpret instructions as before (called `native ClearType')[2][3]. + * The font designer then regains full control and is responsible for + * making the font work correctly with ClearType without any + * hand-holding by the interpreter or rasterizer[4].
