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 @@ -4159,7 +4345,7 @@ Extensions support: ------------------------------------------------------------------------ -Copyright 2000-2013 by +Copyright 2000-2015 by David Turner, Robert Wilhelm, and Werner Lemberg.

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. 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. + * + * _Native_ _ClearType_ _Mode_ + * + * (Not to be confused with `natural widths'.) This mode removes all + * the exceptions in the TrueType interpreter when running with + * ClearType. Any issues on widths would still apply, though. + * + */ + + + /************************************************************************** + * + * @property: + * interpreter-version + * + * @description: + * Currently, two versions are available, representing the bytecode + * interpreter with and without subpixel hinting support, + * respectively.

The main idea is to render at a + * much increased horizontal resolution, then sampling down the created + * output to subpixel precision. However, many older fonts are not + * suited to this and must be specially taken care of by applying + * (hardcoded) font-specific tweaks. + * + * Details on subpixel hinting and some of the necessary tweaks can be + * found in Greg Hitchcock's whitepaper at + * `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'. + * + * The following example code demonstrates how to activate subpixel + * hinting (omitting the error handling). + * + * { + * FT_Library library; + * FT_Face face; + * FT_UInt interpreter_version = TT_INTERPRETER_VERSION_38; + * + * + * FT_Init_FreeType( &library ); + * + * FT_Property_Set( library, "truetype", + * "interpreter-version", + * &interpreter_version ); + * } + * + * @note: + * This property can be used with @FT_Property_Get also. + * + */ + + + /************************************************************************** + * + * @enum: + * TT_INTERPRETER_VERSION_XXX + * + * @description: + * A list of constants used for the @interpreter-version property to + * select the hinting engine for Truetype fonts. + * + * The numeric value in the constant names represents the version + * number as returned by the `GETINFO' bytecode instruction. + * + * @values: + * TT_INTERPRETER_VERSION_35 :: + * Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in + * Windows~98; only grayscale and B/W rasterizing is supported. + * + * TT_INTERPRETER_VERSION_38 :: + * Version~38 corresponds to MS rasterizer v.1.9; it is roughly + * equivalent to the hinting provided by DirectWrite ClearType (as + * can be found, for example, in the Internet Explorer~9 running on + * Windows~7). + * + * @note: + * This property controls the behaviour of the bytecode interpreter + * and thus how outlines get hinted.
