Nikolaus Waxweiler	a6feefdfef	[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.	6 years ago
Nikolaus Waxweiler	f72b00746c	[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.	6 years ago
Werner Lemberg	f686ad46a3	Update copyright years.	6 years ago
John Tytgat	f61f49fef7	[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.	6 years ago
Chris Liddell	b75abeb5e6	[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'.	6 years ago
Werner Lemberg	b89166cc4d	* src/autofit/aflatin2.c: Some fixes from `aflatin.c' (#55310 ).	6 years ago

Werner Lemberg	3e8a2283f5	* 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.	6 years ago
Werner Lemberg	f1b6183f36	[bdf] Ignore data after `ENDFONT'. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10798 * src/bdf/bdflib.c (_bdf_parse_end): New function. (_bdf_parse_glyphs): Switch to `_bdf_parse_end' after `ENDFONT' has been encountered.	6 years ago

Chris Liddell	78a1e69517	[type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls. For multiple master fonts, common usage (in Postscript) is to modify the WeightVector of an existing font instance, this addition supports that use. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Set_MM_WeightVector, FT_Get_MM_WeightVector): New API functions. * include/freetype/internalservices/svmm.h (FT_Set_MM_WeightVector_Func, FT_Get_MM_WeightVector_Func): New function types.

(FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/cffcffdrivr.c (cff_set_mm_weightvector, cff_get_mm_weightvector): New functions. (cff_service_multi_masters): Register them. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. This driver doesn't use the new interface. * src/type1/t1load.c (T1_Set_MM_WeightVector, T1_Get_MM_WeightVector): New functions. * src/type1/t1driver.c (t1_service_multi_masters): Register them. * src/type1/t1load.h: Updated.	6 years ago
Ben Wagner	1fc6937f7f	[cff] Fix compiler warning (#55105 ). * src/cff/cffparse.c (cff_parser_run): Guard label only used if CFF_CONFIG_OPTION_OLD_ENGINE is active.	6 years ago
Ben Wagner	74cdd75f6f	[truetype] Fix numeric overflow (#55103 ). * src/truetype/ttgload.c (compute_glyph_metrics): Use `SUB_LONG'.	6 years ago
Alexei Podtelezhnikov	1c4004bb34	[builds] Belated DLL support with vc2002-vc2008.
