Werner Lemberg f92fa393 2019-02-20T16:04:48 Minor documentation fixes.
Werner Lemberg de8de1ce 2019-02-20T12:48:36 Minor (whitespace, spelling, doc update).
Wink Saville 0ac69211 2019-02-16T07:05:39 * src/autofit/afwarp.h (af_warper_compute): Fix declaration.
Werner Lemberg 29b302ad 2019-02-16T07:05:24 Minor.
Werner Lemberg b66d6a91 2019-02-06T07:38:25 CHANGES: Document recent metrics change from Nikolaus.
Nikolaus Waxweiler a6feefdf 2019-02-02T15:50:57 [truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics. Instead of setting typo or win metrics as the new FT_Face metrics indiscriminately, apply only typo deltas to the currently active FT_Face metrics. This prevents line height differences when e.g. the default outlines were used as the regular face and instances for everything else. * src/truetype/ttgxvar.c (tt_apply_mvar): Implement.
Nikolaus Waxweiler f72b0074 2019-02-02T15:45:31 [sfnt] Use typo metrics if OS/2 fsSelection USE_TYPO_METRICS bit is set. If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set, use the sTypo* set of values to compute the FT_Face's ascender, descender and height. Otherwise, fall back to old behavior. * src/sfnt/sfobjs.c (sfnt_load_face): Implement.
Werner Lemberg f686ad46 2019-01-22T20:31:44 Update copyright years.
John Tytgat f61f49fe 2019-01-18T13:25:23 [sfnt] Handle TT fonts having two PostScript font names (#55471). * src/sfnt/sfdriver.c (sfnt_get_name_id): Prefer English over any other language found for PostScript font names.
Alexei Podtelezhnikov 1e7a8f30 2019-01-08T20:54:13 [psaux, type1] Align tracing.
Chris Liddell b75abeb5 2019-01-08T20:51:39 [psaux] Fix closepath (#55414). All of the Type 1 path building is done with code common to the revised CFF engine, with the exception of closepath, which was still calling ps_builder_close_contour(), thus previously cached segments were not always written to the path, and glyph corruption, or even invalid outlines were possible. * src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>: Switch to calling `cf2_glyphpath_closeOpenPath'.
Nikhil Ramakrishnan 2875ada1 2018-12-30T20:02:08 Minor documentation fix.
Werner Lemberg b89166cc 2018-12-29T08:55:01 * src/autofit/aflatin2.c: Some fixes from `aflatin.c' (#55310).

Werner Lemberg 2b4e61e4 2018-12-12T09:36:39 Minor documentation fixes.
Werner Lemberg 3e8a2283 2018-12-11T23:54:17 * src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test. `control_len' only gets its value from `n_ins' (and vice versa), which is always read as `unsigned short' and thus can't be larger than 0xFFFF.
Werner Lemberg 0c83ba6d 2018-12-10T12:11:54 Minor documentation updates and fixes.

Alexei Podtelezhnikov 1c4004bb 2018-11-25T23:19:39 [builds] Belated DLL support with vc2002-vc2008. The solution and project files should be automatically upgraded for the approriate Visual C++ version. * builds/windows/visualc/freetype.{sln,vcproj}: Major upgrades. * builds/windows/visualc/index.html: Document the change. * builds/windows/vc2005, builds/windows/vc2008: Removed as redundant.

Werner Lemberg 0c4feb72 2018-10-17T11:25:32 * CMakeLists.txt: Specify `RUNTIME DESTINATION'. This is needed for DLL builds.
Werner Lemberg 42885493 2018-10-10T12:21:10 Minor.
Werner Lemberg 912e174c 2018-10-07T09:28:52 A missing Unicode cmap is not a fatal error. This is a follow-up to the previous commit. * src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c (sfnt_load_face), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Implement it.

Alexei Podtelezhnikov 877aa1b2 2018-09-27T21:17:36 Align FreeType with standard C memory management. * include/freetype/ftsystem.h: Include FT_TYPES_H. (*FT_Alloc_Func, *FT_Realloc_Func): Use size_t for the size arguments. * src/raster/ftmisc.h: Ditto. * builds/amiga/src/base/ftsystem.c, builds/unix/ftsystem.c, * builds/vms/ftsystem.c, src/base/ftsystem.c (ft_alloc, ft_realloc): Use size_t for the size arguments. * src/base/ftdbgmem.c (ft_mem_debug_alloc, ft_mem_debug_realloc): Use FT_Offset, aka size_t, for the size arguments.
Alexei Podtelezhnikov 4500c701 2018-09-26T22:04:50 Typo.
Werner Lemberg efe7f648 2018-09-25T09:16:45 Typo.
Werner Lemberg a9af6914 2018-09-25T09:10:09 Fix handing of `FT_Bool'. Before this commit we had code like (FT_Bool)( globals->glyph_styles[gindex] & 0x8000) Since `FT_Bool' is defined to be an `unsigned char', the code evaluated to something like (unsigned char)( 0x8532 & 0x8000) which in turn expanded to (unsigned char)( 0x8000) and finally yielded 0x00 – i.e., false – not as expected. Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>. * include/freetype/fttypes.h (FT_BOOL): Add a comparison against zero so that we always have a Boolean expression. */*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where possible.
Alexei Podtelezhnikov 0f122fef 2018-09-23T21:46:26 [bdf] Speed up charmap access. This makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster. * src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Help binary search with continuous prediction.
Alexei Podtelezhnikov 793a9ff9 2018-09-22T14:38:00 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Another tweak. This one should be clearer. When the rounded monochrome bbox collapses we add a pixel that covers most if not all original cbox.
Alexei Podtelezhnikov f26d5775 2018-09-21T20:34:58 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Further tweak.
Werner Lemberg abd997aa 2018-09-21T12:50:32 Improve documentation of `FT_LOAD_NO_RECURSE'.
Ben Wagner 335528e1 2018-09-21T11:26:37 Improve auto-hinter handling of bitmap fonts (#54681). For bitmap fonts, `FT_Load_Glyph' should either return an error or not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this case `FT_Load_Glyph' calls into the auto-hinter which calls back into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path (even though it doesn't have any path). It appears that the auto-hinter should not be called when the face doesn't have outlines. The current test for using the auto-hinter in `FT_Load_Glyph' checks if the driver supports scalable outlines, but not if the face supports scalable outlines. * src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have scalable outlines.
Werner Lemberg c168cc3b 2018-09-21T11:09:27 [raster] Fix disappearing vertical lines (#54589). * src/raster/ftraster.c (Vertical_Sweep_Span): Handle special case where both left and right outline exactly pass pixel centers.
Werner Lemberg 493aa68f 2018-09-21T08:32:22 [base] Some comments.
Alexei Podtelezhnikov 2a9850c4 2018-09-20T22:40:32 * src/base/ftobjs.c (ft_glyphslot_reset_bimap): Tiny rounding tweak. This adds pixels in case a contour goes through the center and they need to be turned on in the b/w rasterizer.
Alexei Podtelezhnikov c1b21f47 2018-09-20T22:14:46 [pcf] Replace charmap implementation. PCF comes with charmap lookup table, aka PCF encodings. Using it directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times faster than the original BDF-like binary searches. * src/pcf/pcf.h (PCF_EncodingRec): Removed. (PCF_FaceRec): Remove `nencodings' and `encodings'. * src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Replaced. * src/pcf/pcfread.c (pcf_get_encodings): Store data differently.
Werner Lemberg 8e950680 2018-09-20T06:26:34 [base] Remove unused function `FT_GlyphLoader_CopyPoints'. * include/freetype/internal/ftgloadr.h, src/base/ftgloadr.c (FT_GlyphLoader_CopyPoints): Do it.
Alexei Podtelezhnikov 7f93c977 2018-09-19T22:45:45 [pcf] Prepare to replace charmap implementation. * src/pcf/pcf.h (PCF_Face): Updated to include... (PCF_EncRec): ... this new structure to store charmap geometry. * src/pcf/pcfread.c (pcf_get_encodings): Store charmap geometry.
Alexei Podtelezhnikov d629c2ba 2018-09-18T17:11:48 Remove unused fields. * src/pcf.h (PCF_FaceRec): Remove `charmap' and `charmap_handle'. * src/bdfdrvr.h (BDF_FaceRec): Ditto. * src/winfonts/winfnt.h (FNT_FaceRec): Ditto.
Werner Lemberg dfddc2d9 2018-09-17T08:03:57 [pshinter] Handle numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10396 * src/pshinter/pshglob.c: Include FT_INTERNAL_CALC_H. (psh_blues_snap_stems): Mask numeric overflow.

John Tytgat 6b53300b 2018-09-12T08:08:09 [sfnt] Better PS name handling (#54629). * src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks. (get_win_string, get_apple_string): Return NULL when the PostScript font name characters is not according to specification. (get_win_string): Make trace output work if the high byte if non-zero. (sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred Win PS name (when there is also an Apple PS name); change this into a fallback to Apple PS name in case the Win PS name is invalid.
Werner Lemberg 65681e6d 2018-09-12T07:40:49 [truetype] Improve VF check. Triggered by https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10255 * src/truetype/ttgxvar.c (ft_var_load_gvar): Use better limit check for `tupleCount'.
