dff40d03	2017-10-12T18:13:21	Add T1_CONFIG_OPTION_OLD_ENGINE configuration option. This controls whether the old Type 1 engine gets compiled into FreeType. It is disabled by default. * devel/ftoption.h, include/freetype/config/ftoption.h (T1_CONFIG_OPTION_OLD_ENGINE): New macro. * include/freetype/internal/psaux.h (PS_Decoder): Remove unused field. * include/freetype/internal/psaux.h, src/cid/cidgload.c (cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c (ps_builder_add_point), src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode, t1_decoder_parse_glyph, t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h, src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround relevant code with macro. Minor code changes.
78df3c27	2017-10-12T18:13:08	Extract width parsing from Type 1 parser. Duplicate the fast advance width calculations from the old parser. This is to facilitate adding options for compiling out the old parser. * src/psaux/t1decode.{c,h} (t1_decoder_parse_metrics): New function. * include/freetype/internal/psaux.h (T1_Decoder_Funcs): New entry `parse_metrics'. * src/psaux/psauxmod.c: Set the new entry. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Separate conditional for selecting engine.
8768536c	2017-10-12T00:13:51	[autofit] Better visualize table tracing in source code.
64985519	2017-10-09T07:45:03	* src/base/ftoutln.c (FT_Outline_Translate): Fix integer overflow. Reported as https://bugs.chromium.org/p/chromium/issues/detail?id=772775
b7e43f7d	2017-10-08T11:58:39	* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Integer overflows. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3579
08e2e311	2017-10-08T10:37:50	Document global size metrics needed for native bytecode hinting (#52165).

7bfcaaca	2017-10-07T13:14:38	[sfnt] Adjust behaviour of PS font names for variation fonts. * src/sfnt/sfdriver.c (sfnt_get_var_ps_name): Use a named instance's PS name only if no variation is applied.
f89c67f0	2017-10-07T13:10:53	[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance. (TT_Set_Var_Design): Use current named instance for default coordinates. * src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.

d52dd7f3	2017-09-25T08:22:26	Fix Type 1 hinting. Type 1 hinting breaks sometimes when mid-charstring hints should have been in the initial hintmap. This fix adds a preprocessing pass that reads all hints and builds the correct initial hintmap first, before proceeding to build the glyph outline. * src/psaux/psintrp.c (cf2_interpT2CharString): New `initial_map_ready' boolean flag. Ignore outline commands and hint changes on first pass. <cf2_cmdENDCHAR>: Add section to build hintmap and rewind.

93e3cffd	2017-09-25T08:08:21	Change subfont synthesis for CID fonts. Change `t1_make_subfont' to take in the Private dict record as an argument. This is because Type 1 and CID font records in FreeType have this in different places. * src/psaux/psobjs.c (t1_make_subfont): Change `T1_Face' to `FT_Face' so that CID is also accepted. Take `PS_Private' as an argument and let caller figure out where the Private dict actually is. Update references. * include/freetype/internal/psaux.h, src/psaux/psobjs.h: Update declaration. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Update call.

d813b5da	2017-09-25T08:04:09	Extend Adobe interpreter (seac). This concludes the changes needed to add Type 1 support. * src/psaux/psintrp.c: Update includes. (cf2_interpT2CharString) <cf2_escSEAC>: Implement this similarly to implied seac for CFF. * src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New function to look up the glyph index. * src/psaux/psft.c (cf2_getT1SeacComponent, cf2_freeT1SeacComponent): New functions to get the charstrings for seac components. * src/psaux/t1decode.h, src/psaux/psft.h: Update declarations.
d55a701d	2017-09-25T07:59:41	Extend Adobe interpreter (flex in callothersubr). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escCALLOTHERSUBR>: Fix Flex feature handling (OtherSubrs 0, 1, 2). <cf2_cmdRMOVETO>: Do not actually move the `glyphPath' while doing flex. This is to avoid closing the current contour.
96682559	2017-09-25T07:54:02	Extend Adobe interpreter (callothersubr). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escCALLOTHERSUBR>: Copy code from `t1_decoder_parse_charstrings' (in `t1decode.c'). OtherSubr 3 (change hints) should reset the hintmask, so that the new hints are applied. Fix function calls and stack access.
77c1b331	2017-09-25T07:50:03	Extend Adobe interpreter (pop). * src/psaux/psintrp.c (cf2_interpT2CharString): Change how unhandled OtherSubr results are stored. Implement the PostScript stack using an array. <cf2_escPOP>: Ensure that the stack is not cleared after getting `OtherSubr' results. Fix stack access.
1e4d3dc8	2017-09-25T07:47:10	Extend Adobe interpreter (callsubr). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>: Type 1 mode. * src/psaux/psft.c (cf2_initLocalRegionBuffer): Add Type 1 mode.
4b58c518	2017-09-25T07:44:56	Extend Adobe interpreter (div, four-byte numbers). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add Type 1 mode. Type 1 requires large integers to be followed by `div'; cf. `Adobe Type 1 Font Format', section 6.2. <op == 255>: Push Type 1 four-byte numbers as `Int' always. This is to ensure `div' and `callsubr' get values they can use.
81b86c45	2017-09-25T07:14:18	Extend Adobe interpreter (hstem, vstem, hstem3, vstem3). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM>: Add correction for left sidebearing in Type 1 mode. Allow adding hints mid-charstring. <cf2_escVSTEM3, cf2_escHSTEM3>: Translate into equivalent commands for three normal stem hints. This requires some recalculation of stem positions. Correction for left sidebearing.
e180afa9	2017-09-25T07:11:03	Extend Adobe interpreter (hsbw, sbw). * src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the first operation in a Type 1 charstring. (cf2_interpT2CharString): Remove unused variables. <cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw' must be the first operation in a Type 1 charstring. <cf2_cmdHSBW, cf2_escSBW>: Fix data access and add correction for left sidebearing.
2f4abaec	2017-09-25T07:04:43	Extend Adobe interpreter (setcurrentpoint). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSETCURRENTPT>: Fix stack access.
4ed1b98d	2017-09-25T07:02:53	Extend Adobe interpreter (closepath). * src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>: Use the right builder function. We can use the `haveWidth' boolean already present, instead of implementing `parse_state'.
37ed70f6	2017-09-25T06:59:26	Add Type 1 operations to Adobe CFF interpreter. The following Type 1 specific ops have been added (copied from `t1decode'): closepath vstem3 hstem3 seac sbw callothersubr pop setcurrentpoint hsbw The following require a Type 1 mode, because of differences in specification: hstem vstem vmoveto callsubr div rmoveto hmoveto Numbers The subsequent commits will implement these changes and adapt accesses of data and objects to the new interpreter. NOTE: Will not compile in the meantime! * src/psaux/psintrp.c: Add opcodes to enum. (cf2_interpT2CharString): Copy relevant code over from `t1_decoder_parse_charstrings' (in `t1decode.c').
283ef285	2017-09-25T06:54:16	Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags.
6eb03f8f	2017-09-25T06:49:41	Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call.
cb3f4c61	2017-09-25T06:44:51	Add missing objects for Type 1 (1/2). Move `CF2_Font' instance to `PS_Decoder'. This is the context for the interpreter and since it is currently stored in `CFF_Font', is unavailable in Type 1 mode. * include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): New `cf2_instance' field. * src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to `PS_Decoder'. * src/psaux/t1decode.c (t1_decoder_done): Add finalization code. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Update accesses.
7e185dcd	2017-09-25T06:40:32	Allow `type1' module to use the Adobe engine. Add the callback and some conditionals to switch between the two engines. * include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Change function declarations. * src/psaux/psauxmod.c (T1_Decoder_FuncsRec): Register the callbacks. * src/psaux/psobjs.c (ps_builder_add_point): Add conditionals for number conversion. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add code to choose which renderer to use. * src/cid/cidgload.c (cid_load_glyph): Update call. * src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update includes.
97704b15	2017-09-25T06:33:28	Add Adobe engine configuration. Use the previously changed PS_Driver in type1 module to store hinting engine configuration. * include/freetype/ftt1drv.h: New file. Duplicate and rename config options from CFF. * include/freetype/config/ftheader.h (FT_TYPE1_DRIVER_H): New macro. * src/type1/t1driver.c (t1_driver_class): Update declaration. * src/type1/t1objs.c: Include FT_TYPE1_DRIVER_H. (T1_Driver_Init): Update code.
645d1b86	2017-09-25T06:28:25	Move and rename `CFF_Driver'. This is so that we can use the same hinting engine parameters for Type 1. * include/freetype/internal/cffotypes.h (CFF_Driver): Rename and move to... * include/freetype/internal/psaux.h (PS_Driver): ...here. * src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c, src/cff/cffobjs.c, src/cff/cffobjs.h, src/psaux/psft.c, src/psaux/psobjs.c: Update references.
d23affe1	2017-09-25T06:22:52	Reorganize object fields. Make some fields more generic, so that we can access them the same way regardless of Type 1 or CFF. * include/freetype/internal/psaux.h (PS_Builder): Change `TT_Face' to `FT_Face'. Remove unused fields. * src/psaux/psft.c: Update all accesses of `PS_Builder.face'. Add some asserts to guard against casting `T1_Face' as `TT_Face'. * src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow `CFF_GlyphSlot', so that we can pretend they are the same in the interpreter. * src/psaux/psobjs.c (ps_builder_init, ps_builder_add_point): Updated with above changes.
9428ee42	2017-09-25T06:15:46	Prepare for Type 1 mode. Add some checks for Type 1 data passing through. * src/psaux/psfont.h (CF2_Font): Add `isT1' flag. * src/psaux/psfont.c (cf2_font_setup): Skip the variations and blend code which is not applicable for Type 1. * src/psaux/psft.c (cf2_decoder_parse_charstrings): Avoid accessing `decoder->cff' in Type 1 mode. Copy `is_t1' flag to `CF2_Font'.
62f095f0	2017-09-25T09:25:55	[psaux, cff] Move Adobe's engine components into `psaux' module. This is the first patch of a sequence to move the Type 2 charstring processing capability from the `cff' module to the `psaux' module. NOTE: Does not compile! * src/cff/cf2: Move these files to... src/psaux/cf2: Here. src/cff/Jamfile (_sources), src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H), src/cff/cff.c, src/cff/cffgload.c: Remove file references. * src/psaux/Jamfile (_sources), src/psaux/rules.mk, src/psaux/psaux.c (PSAUX_DRV_SRC, PSAUX_DRV_H): Add file references.
02e80da6	2017-09-24T22:18:34	Tweak per-face LCD filtering controls. Thing are simpler with a NULL-function pointer. * include/freetype/internal/ftobjs.h (FT_Face_InternalRec): New pointer to the filter function. (FT_LibraryRec): Remove unused `lcd_filter'. (FT_Bitmap_LcdFilterFunc, ft_lcd_filter_fir): Move from here... * include/freetype/ftlcdfil.h (FT_Bitmap_LcdFilterFunc, ft_lcd_filter_fir): ... to here. * src/base/ftobjs.c (ft_open_face_internal): NULL-initialize the per-face filter. (FT_Face_Properties): Set it. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Simplify. * src/base/ftlcdfil.c (ft_lcd_filter_fir, FT_Libary_SetLcdFilter): Minor.

e7202069	2017-09-24T09:16:39	Minor.
6d403d08	2017-09-24T09:06:01	Fix handling of ValueRecords. For GPOS pair positioning format 1 the description of ValueRecords in the OpenType specification (1.8.2, from today) is wrong – the offset has to be taken from the parent structure; in this case the `PairSet' table. * src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'. (otv_PairPos_validate): Adjust.
0da0faf0	2017-09-24T09:13:41	[otvalid] Handle `GSUB' and `GPOS' v1.1 tables. * src/otvalid/otvgsub.c (otv_GSUB_validate), src/otvalid/otvgpos.c (otv_GPOS_validate): Implement it.

3645982a	2017-09-22T07:53:25	[otvalid] Macros for 32bit offset support. * src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE32, OTV_OPTIONAL_OFFSET32, OTV_SIZE_CHECK32): New macros.
21c235ec	2017-09-22T07:28:25	[otvalid] Whitespace.

b19cdc9c	2017-09-21T11:02:35	[truetype] Fix `mmvar' array pointers, part 2. The previous commit was incomplete. * src/truetype/ttgxvar.c: Properly initialize sub-array offsets for `master' also.
3b3cb32d	2017-09-21T09:03:20	[truetype] Fix `mmvar' array pointers. Without this change, clang's AddressSanitizer reports many runtime errors due to misaligned addresses. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Use multiples of pointer size for sub-array offsets into `mmvar'.
843e0dc9	2017-09-20T22:19:01	Restore FT_EXPORT documentation.

b00be9f6	2017-09-19T07:12:03	[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
8b0d2e9e	2017-09-18T22:54:49	[build] Declutter Visual C++ 2010-2017 project. * build/windows/vc2010/freetype.vcxproj: Use MaxSpeed (/02) optimization for Release configuration throughout the project.

2017-10-07T13:10:53

[cff, truetype] Adjust behaviour of named instances. This commit completely separates the interaction between named instances and variation functions. In particular, resetting the variation returns to the current named instance (if set) and not to the base font. As a side effect, variation functions no longer change the named instance index. * src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance' function. Also apply `MVAR' table to named instances. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast. (tt_set_mm_blend): No longer check whether requested variation coincides with a named instance.

2017-09-25T08:22:26

Fix Type 1 hinting. Type 1 hinting breaks sometimes when mid-charstring hints should have been in the initial hintmap. This fix adds a preprocessing pass that reads all hints and builds the correct initial hintmap first, before proceeding to build the glyph outline. * src/psaux/psintrp.c (cf2_interpT2CharString): New `initial_map_ready' boolean flag. Ignore outline commands and hint changes on first pass. <cf2_cmdENDCHAR>: Add section to build hintmap and rewind.

Extend Adobe interpreter (div, four-byte numbers). * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escDIV>: Add Type 1 mode. Type 1 requires large integers to be followed by `div'; cf. `Adobe Type 1 Font Format', section 6.2. <op == 255>: Push Type 1 four-byte numbers as `Int' always. This is to ensure `div' and `callsubr' get values they can use.

2017-09-25T06:59:26

Add Type 1 operations to Adobe CFF interpreter. The following Type 1 specific ops have been added (copied from `t1decode'): closepath vstem3 hstem3 seac sbw callothersubr pop setcurrentpoint hsbw The following require a Type 1 mode, because of differences in specification: hstem vstem vmoveto callsubr div rmoveto hmoveto Numbers The subsequent commits will implement these changes and adapt accesses of data and objects to the new interpreter. NOTE: Will not compile in the meantime! * src/psaux/psintrp.c: Add opcodes to enum. (cf2_interpT2CharString): Copy relevant code over from `t1_decoder_parse_charstrings' (in `t1decode.c').

Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only. Set the `force_scaling' flag. (T1_Parse_Glyph): Updated. (T1_Load_Glyph): Add `hinting' and `scaled' flags.

6eb03f8f

2017-09-25T06:49:41

Add missing objects (2/2). Synthesize a `SubFont' object for Type 1 fonts. This is used in the interpreter to access Private dict data, which are stored in different places for Type 1 and CFF. This allows the same data to be used in either mode. * src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values to a dummy `CFF_SubFont' object. This is similar to `cff_make_private_dict'. * src/psaux/psobjs.h: Add the new declaration. * include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto. Add this to the PSAux Service for future use with CID fonts. * src/type1/t1gload.c: Include FT_INTERNAL_CFF_TYPES_H. (T1_Parse_Glyph_And_Get_Char_String): Add the call.

[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
