Werner Lemberg 9ac9060d 2018-06-03T09:01:17 [GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

Shao Yu Zhang f04d8175 2018-05-13T03:25:09 [sfnt] Preliminary support of coloured layer outlines. This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

Werner Lemberg 2df73b39 2017-12-18T23:32:32 [sfnt] Fix charmap type 2 iterator (#52646). The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131).

Werner Lemberg 39ce3ac4 2017-09-16T19:08:17 * Version 2.8.1 released. ========================= Tag sources with `VER-2-8-1'. * docs/VERSION.TXT: Add entry for version 2.8.1. * docs/CHANGES: Updated. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.8/2.8.1/, s/28/281/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 21:0:15. * CMakeLists.txt (VERSION_PATCH): Set to 1.
suzuki toshiya b757ddb1 2017-09-13T22:17:03 [sfnt] lowest gcc for vectors ( e1d0249e ) is changed to 4.7. __builtin_shuffle() was introduced in gcc-4.7. The lowest gcc to enable vector operation is delayed from 4.6 to 4.7. * src/sfnt/pngshim.c (premultiply_data): Fix cpp-macro to enable the vector operation, to change the lowest gcc version from 4.6 to 4.7.
suzuki toshiya 21658c31 2017-09-12T15:59:18 [autofit, sfnt] Fix for `make multi'. * src/autofit/afshaper.c: Include FT_ADVANCE_H, to use FT_Get_Advance() in it. * src/sfnt/ttcmap.c: Include FT_SERVICE_POSTSCRIPT_CMAPS_H to use PS_Unicodes in it, also include `ttpost.h' to use tt_face_get_ps_name() in it.
Werner Lemberg 3e4b7997 2017-09-11T08:51:44 * src/sfnt/ttkern.c (tt_face_load_kern): Reject format 2 tables. Reported by Behdad.
suzuki toshiya 5c4e40d7 2017-09-09T00:59:33 [sfnt, truetype] Register the tags for marginal fonts. The first 32bit of standard TrueType variants is 0x00010000, `OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources starting 0xA5 followed by `kbd' or `lst'. Considering the following data could be parsed as conventional TrueType fonts, the header checking is updated to allow these tags. It seems that recent Mac OS X has already switched to normal TTF for these fonts. See the discussion at http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0 * include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header tags for Keyboard.dfont and LastResort.dfont. * src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource starts with TTAG_0xA5kbd or TTAG_0xA5lst. * src/truetype/ttobjs.c (tt_face_init): Accept the face with the format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
Werner Lemberg e1d0249e 2017-08-23T08:18:22 [sfnt] Fix clang compilation (#51788). * src/sfnt/pngshim.c (premultiply_data): Use vectors instead of scalars. (vector_shuffle): New macro to take of a different built-in function name on clang.
Alexei Podtelezhnikov 7653c765 2017-08-17T21:28:32 [sfnt] Avoid synthetic unicode for symbol fonts with PUA. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=754574 * src/sfnt/sfobjs.c (sfnt_load_face): Check for FT_ENCODING_MS_SYMBOL.
Werner Lemberg cadd29de 2017-08-16T13:32:17 * src/sfnt/pngshim.c (premultiply_data): Fix compiler warnings.
Behdad Esfahbod c9d7c03f 2017-08-15T08:48:17 [sfnt] Speed up PNG image loading. This reduces the overhead of `premultiply_data' by 60%. * src/sfnt/pngshim.c (premultiply_data): Provide code which uses gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a time.
Werner Lemberg b45043c4 2017-08-11T09:34:20 [sfnt, truetype] Improve handling of missing sbits. Requested by Behdad. Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain entries in the bitmap strike(s) for empty glyphs. Instead, they rely that a space glyph gets created from the font's metrics data. This commit makes FreeType behave accordingly. * include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error code. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes to make a distinction between a missing bitmap in a composite and a simple missing bitmap. * src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a bitmap-only font), synthesize an empty bitmap glyph if metrics are available.
Alexei Podtelezhnikov a9d8e90c 2017-08-08T21:42:37 * src/sftnt/ttpost.c (format): Use otspec-compliant versions.
Werner Lemberg ce367774 2017-08-01T08:24:51 [sfnt, truetype] Minor adjustments for OpenType 1.8.2. * src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now (tighter) limits. * src/truetype/ttgload.c (load_truetype_glyph): The new OpenType version explicitly allows all negative values for the number of contours if we have a composite glyph (this is for better backwards compatibility I guess), but it still recommends value -1.
Werner Lemberg cf8d9b4c 2017-07-05T23:07:01 * src/sfnt/ttcmap.c (tt_cmap_unicode_class_rec): Fix warning.
Alexei Podtelezhnikov abeb28f1 2017-07-01T16:48:32 * src/sfnt/sfobjs.c (sfnt_load_face): Ignore No_Unicode_Glyph_Name.

(tt_get_cmap_info): Make sure the callback is available. * src/sfnt/sfobjs.c (sfnt_load_face) [FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: If Unicode charmap is missing, synthesize one. * include/freetype/config/ftoption.h: Document it. * devel/ftoption.h: Ditto.
Werner Lemberg 390048fa 2017-06-20T18:03:20 Remove deprecated comment.
Werner Lemberg 79e3789f 2017-06-14T07:51:04 * src/winfonts/winfnt.c (FNT_Face_Init): Don't set active encoding. FreeType only sets a default active encoding for Unicode.

Wojciech Mamrak 565f5a7d 2017-03-27T09:19:14 [sfnt] Minor improvement for handling kern tables. * src/sfnt/ttkern.c (tt_face_load_kern): Don't check for cross-stream kerning tables since we reject format 2 tables later on anyways. Modify code for limit test... (tt_face_get_kerning): ... to avoid a limit test here.
Werner Lemberg 913f436d 2017-03-23T18:37:06 [sfnt] Fix check for default named instance. * src/sfnt/sfobjs.c (sfnt_init_face): A `fixed' number needs four bytes, not two...

Werner Lemberg 4a32dce9 2017-03-14T19:32:12 [sfnt] Implement PS names for font instances [1/3]. Add 128bit MurmurHash 3 function. Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. * src/sfnt/sfdriver.c (ROTL32): New macro. (fmix32, murmur_hash_3_128): New functions.
Werner Lemberg 7bbb91fb 2017-03-08T15:09:41 [sfnt] Another fix for buggy variation fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=759 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `CFF2' present also (which gets priority).
Werner Lemberg 77930974 2017-03-07T17:27:58 [sfnt] Improve handling for buggy variation fonts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=738 * src/sfnt/sfobjs.c (sfnt_init_face): While setting number of instances to zero for `CFF' fonts table, ensure that there is no `glyf' present also (which gets priority).
Werner Lemberg 27fee7f8 2017-03-06T20:45:44 [sfnt, truetype] Always provide default instance. As documented in the OpenType specification, an entry for the default instance may be omitted in the named instance table. In particular this means that even if there is no named instance table in the font we actually do have a named instance, namely the default instance. For consistency, we always want the default instance in our list of named instances. If it is missing, we try to synthesize it. * src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default instance is in the table of named instances. Otherwise adjust number of instances. * src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H. (TT_Get_MM_Var): Use `face->root.style_flags' as the number of named instances. Sythesize a named instance entry if necessary. (tt_done_blend): Free `normalized_stylecoords'.
Werner Lemberg c1b000da 2017-03-05T20:23:35 [sfnt] Remove redundant code. * src/sfnt/sfobjs.c (sfnt_init_face): Remove second test for `num_instances', which will always succeed.
