Werner Lemberg c0414119 2023-05-06T18:57:42 * src/cff/*: Clean up interface. Ensure that all driver functions use the signature of the service or driver. This avoids pointer mismatches, which are technically undefined behaviour. Recent compilers are more picky in catching them as part of Control Flow Integrity tests.
Werner Lemberg 9a3d05d9 2023-04-26T19:00:05 * src/ttgxvar.c: Minor changes. (TT_Get_MM_Var): Improve tracing messages. (tt_set_mm_blend): Minor speed-up.

Alexei Podtelezhnikov e95e6234 2023-03-02T17:58:03 * src/cff/cffload.c (cff_subfont_load): Synonymous update.
Alexei Podtelezhnikov 6423ddb8 2023-02-25T21:54:21 * src/cff/cffload.c (cff_encoding_load): Optimize array zeroing. This is unnecessary for predefined standard and expert encodings. Even for custom encodings the arrays might be already zeroed when CFF_FontRec is created but we keep it just in case.

Ben Wagner b5e003f1 2021-10-21T09:48:38 [cff] Commit vstore data and regions on allocation. The vstore->regionCount and vstore->dataCount were read directly from the data. However, vstore->varRegionList and vstore->varData would still contain uninitialized entries with uninitialized pointers in the event of an error, leading to issues when attempting to clean up. Reportd as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=40104 * src/cff/cffload.c (cff_vstore_load): Read the region and data counts into locals and update the vstore counts immediately after each entry becomes free-able.

Werner Lemberg 16586859 2020-06-13T21:15:45 Remove redundant inclusion of `ft2build.h'. * */*: Remove `#include <ft2build.h>' where possible. * include/freetype/freetype.h: Remove cpp error about missing inclusion of `ft2build.h'.
David Turner e1339133 2020-06-08T13:31:55 Make macros for header file names optional. We no longer have to take care of the 8.3 file name limit; this allows us (a) to introduce longer, meaningful file names, and (b) to avoid macro names in `#include' lines altogether since some compilers (most notably Visual C++) doesn't support this properly. */*: Replace #include FOO_H with #include <freetype/foo.h> or something similar. Also update the documentation.

Dave Arnold edf40148 2016-12-15T21:56:44 [cff] Implement CFF2 support (2/2). The font variation code. All parts dependent on the GX code in the `truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. In other words, you can still compile the `cff' module without defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2 support without font variation). * src/cff/cf2font.c (cf2_font_setup): Add support for font variation. * src/cff/cf2font.h (CF2_Font): Add fields for variation data. * src/cff/cf2ft.c (cf2_free_instance): Free blend data.

(CFF_FIELD_BLEND): New macro. (cff_parser_run): Updated. * src/cff/cffparse.h (cff_kind_blend): New enum value. * src/cff/cfftoken.h: Handle `vstore', `vsindex', and `blend' dictionary values. * src/cff/cfftypes.h (CFF_VarData, CFF_AxisCoords, CFF_VarRegion, CFF_VStore, CFF_Blend): New structures. (CFF_FontRecDict): Add `vstore_offset' field. (CFF_Private): Add `vsindex' field. (CFF_SubFont): Add fields for blend data. (CFF_Font): Add `vstore' field. * src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar', since glyph variation data is directly embedded. (TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts.
Dave Arnold 9f62d2ca 2016-12-15T20:27:47 [cff] Implement CFF2 support (1/2). This commit does not contain the blend code for font variation support, which follows in another commit.

Werner Lemberg 14d6b5d7 2015-08-13T15:22:17 [truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks.

Werner Lemberg 94152819 2013-05-04T16:40:12 More fixes for clang's `sanitize' feature. * src/base/ftcalc.c (FT_DivFix): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate, FT_Vector_Length, FT_Vector_Polarize): Ditto. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify. * src/cff/cffload.c (cff_subfont_load): Fix constant. * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed, cff_parse_fixed_dynamic): Use unsigned values for computations which use the left shift operator and convert to signed as the last step. * src/cid/cidload.c (cid_get_offset): Ditto. * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto. * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto. * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
Werner Lemberg 06474c3e 2013-04-13T18:53:28 [cff] Add a new Type 2 interpreter and hinter. This work, written by Dave Arnold <darnold@adobe.com> and fully integrated into FreeType by me, is a donation by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it soon. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver. For convenience, (most of) the new files are committed separately. * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. * include/freetype/ftcffdrv.h: New file to access CFF driver properties. * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error code. * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', and `cf2interp'. * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' and `no_stem_darkening'. * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. * src/cff/cff.c: Include new files. * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle `hinting-engine' and `no-stem-darkening' properties (only the Adobe engine listens to them). * src/cff/cffgload.c: Include `cf2ft.h'. (cff_decoder_prepare): Initialize `current_subfont'. (cff_build_add_point): Handle Adobe engine which uses 16.16 coordinates. (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING separately. Choose rendering engine based on `hinting_engine' property. * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe engine. * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. (cff_driver_init): Set default property values. * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. * src/cff/cf2*.*: New files, containing the Adobe engine.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Werner Lemberg 55127272 2012-11-13T09:22:11 [cff] Add support for OpenType Collections (OTC). * src/cff/cffload.c (cff_font_load): Separate subfont and face index handling to load both pure CFFs with multiple subfonts and OTCs (with multiple faces where each face holds exactly one subfont). * src/cff/cffobjs.c (cff_face_init): Updated.

suzuki toshiya 73aa20ca 2010-09-20T01:30:38 [cff] Truncate the element length at the end of the stream. See Savannah bug #30975. * src/cff/cffload.c (cff_index_access_element): `off2', the offset to the next element is truncated at the end of the stream to prevent invalid I/O. As `off1', the offset to the requested element has been checked by FT_STREAM_SEEK(), `off2' should be checked similarly.

See Savannah bug #30975. * src/cff/cffload.c (cff_charset_compute_cids): Don't increment max_cid after detecting max CID. The array CFF_Charset->cids is allocated by max_cid + 1. (cff_charset_cid_to_gindex): Permit CID is less than or equal to CFF_Charset->max_cid. * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is calculated as CFF_Charset->max_cid + 1.
Werner Lemberg 5220ef58 2010-09-13T07:32:22 Fix minor issues reported by <muktha.narayan@wipro.com>. * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove redundant conditional check. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto. * src/cff/cffload.c (cff_encoding_load): Remove conditional check which always evaluates to `true'. * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points): Ditto. * src/truetype/ttinterp.c (Ins_IUP): Ditto. * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if value is already dereferenced. * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
