Werner Lemberg d42679b9 2023-08-25T18:05:01 Fix clang warnings. * src/cffload.c (cff_blend_doBlend): Fix type of `sum`. * src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Fix type of `word_delta_count`.
Werner Lemberg 3c92e7bf 2023-07-14T18:58:55 [cff] Fix compiler warning. * src/cff/cffparse.c, src/cff/cffparse.h: Make `cff_parse_fixed` a local function.
Skef Iterum 26a7f047 2023-07-11T01:40:25 [cff] Make blend operator work with floats in private dicts. The CFF2 blend operator takes N default values and corresponding sets of deltas and pushes N values specific to a designspace location. CFF has a floating point numeric type and the FreeType blending code was not converting those into its internal 16.16 Fixed type format. Fixes #1243. * src/cff/cffparse.c (do_fixed): Handle floating point numbers. Also fix scaling overflow check for integer-to-fixed conversion. * src/cff/cffload.c (cff_blend_doBlend): Updated.
Ben Wagner 2fb8eda5 2023-06-01T19:38:36 */*: Remove many function pointer casts. In C it is undefined behavior to call a function through a function pointer of a different type. This is now detected by the Control Flow Integrity Sanitizer. All known issues have already been fixed. Prevent any accidental re-introduction by removing function pointer casts when defining services. The services will call the service functions through the function pointers on the service. As a result the functions must have the same type so there should be no need to cast. Removing the casts allows compilers to warn about assignment to an incompatible function pointer type.
Werner Lemberg 416d4c25 2023-05-15T15:44:36 Add new load flag `FT_LOAD_NO_SVG`. Modern color fonts often contain both an 'SVG' and 'COLR' table. FreeType always preferred 'SVG' over 'COLR' (this was a design decision), however, this might not be the right choice for the user. The new flags makes FreeType ignore the 'SVG' table while loading a glyph. Fixes #1229. * include/freetype/freetype.h (FT_LOAD_NO_SVG): New macro. * src/base/ftobjs.c (FT_Load_Glyph), src/cff/cffgload.c (cff_slot_load), src/truetype/ttgload.c (TT_Load_Glyph): Use it.
Werner Lemberg e02a40a4 2023-05-08T20:12:26 * src/cff/cffdrivr.c (cff_glyph_load): Fix guard for `size`. This was forgotten to change in commit 2b54eba36b (in May 2004). Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=58739
Werner Lemberg 5edd6d52 2023-05-08T07:22:59 Minor compiler warning fixes. * src/autofit/afcjk.c (af_cjk_get_standard_widths), src/autofit/aflatin.c (af_latin_get_standard_widths): Use `FT_CALLBACK_DEF`. * src/cff/cffparse.c (cff_parser_run): Initialize and fix allocation of `q`.
Werner Lemberg 4a28ff3d 2023-05-07T09:14:27 * src/cff/cffcmap.c: Signature fixes.
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 c8a24209 2023-04-27T11:40:46 [truetype] Fix PostScript name handling for variation fonts. A variation font's PostScript name of a named instance is usually different from the PostScript name of an unnamed instance. However, if a change between a named instance and an unnamed instance with exactly the same design axis values happened, it was possible that the PostScript name wasn't correctly updated. This commit reorganizes the code to handle this issue within the top-level API functions, using a new service to trigger recomputation of the PostScript name. * include/freetype/internal/services/svmm.h (FT_Construct_PS_Name_Func): New typedef. (FT_Service_MultiMasters): New field `construct_ps_name`. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/base/ftmm.c (FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Call `mm->construct_ps_name` to handle `postscript_name`. (FT_Set_Named_Instance): Call `mm->construct_ps_name` to handle `postscript_name`. Use shortcut. * src/cff/cffdrivr.c (cff_construct_ps_name): New function. (cff_service_multi_masters): Updated. * src/truetype/ttgxvar.c (tt_set_mm_blend): Don't handle `postscript_name`. (TT_Set_MM_Blend): Simplify. (TT_Set_Named_Instance): Return -1 if axis values haven't changed. Don't set `face_index`. (tt_construct_ps_name): New function. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttdriver.c (tt_service_gx_multi_masters): Updated. * src/type1/t1driver.c (t1_service_multi_masters): Updated. * src/type1/t1load.c (T1_Set_MM_Blend): Simplify.
Werner Lemberg 6713b1e4 2023-04-26T12:03:04 [truetype] Fix deactivation of variation font handling. According to the documentation, the functions `FT_Set_Named_Instance`, `FT_Set_MM_Design_Coordinates`, `FT_Set_Var_Design_Coordinates`, and `FT_Set_Var_Blend_Coordinates` can unset the `FT_FACE_FLAG_VARIATION` flag. (The same is true for `FT_Set_MM_WeightVector` but this information was accidentally omitted from the documentation.) However, if a call of these functions didn't change the axis values this could fail because internal shortcuts exited too early. This commit reorganizes the code to handle `FT_FACE_FLAG_VARIATION` in the top-level API functions, also taking care of the issue at hand. * src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_MM_WeightVector, FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Handle `FT_FACE_FLAG_VARIATION`. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design, TT_Set_Named_Instance) Don't handle `FT_FACE_FLAG_VARIATION`. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_WeightVector, T1_Set_MM_Design): Ditto. * src/cff/cffobjs.c (cff_face_init): Use `FT_Set_Named_Instance` instead of low-level functions. * src/truetype/ttobjs.c (tt_face_init): Ditto.

(FT_Service_MultiMasters): Rename `set_instance` to `set_named_instance`. (FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated. * src/base/ftmm.c (FT_Set_Named_Instance): Updated. * src/cff/cffdrivr.c (cff_set_instance): Renamed to... (cff_set_named_instance): ...this.

Werner Lemberg fb982e78 2023-04-26T08:17:17 New Variation Font function `FT_Get_Default_Named_Instance`. * include/freetype/ftmm.h, src/base/ftmm.c (FT_Get_Default_Named_Instance): New function. * include/freetype/internal/services/svmm.h (FT_Get_Default_Named_Instance_Func): New typedef.

Werner Lemberg 966ff5a5 2023-04-28T15:25:20 * src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash. The situation can happen if `FT_New_Face` (or one of its siblings) is called with a negative index to get the number of contained faces, followed immediately by a call to `FT_Get_Postscript_Name`. While this is not a valid use of the FreeType library there is no need for a crash. Fixes #1219.
Werner Lemberg 17a0c5df 2023-04-28T10:40:41 * src/cff/cffdrivr.c (cff_ps_get_font_info): Reject 'CFF2' format.

Ben Wagner e78e2d29 2023-04-06T11:16:29 [sfnt, truetype] Add `size_reset` to `MetricsVariations`. This is a generalization of commit ``` commit e6699596af5c5d6f0ae0ea06e19df87dce088df8 Author: Werner Lemberg <wl@gnu.org> Date: Thu Feb 2 11:38:04 2017 +0100 [truetype] Fix MVAR post-action handling. ``` It is also possible for plain `CFF ` style fonts to contain an `fvar` and `MVAR` table and use `cff_metrics_adjust`. `tt_size_reset` should only be called with `TT_Size` and never with `CFF_Size`. Allow the "metrics-variations" service to specify the correct function (if any) to reset `FT_Size`s after adjusting metrics. * src/truetype/ttobjs.c (tt_size_reset): Split off some functionality into... (tt_size_reset_height): ... this new function. * src/truetype/ttdriver.c (tt_service_metrics_variations): Add `size_reset`. (tt_size_select, tt_size_request): Updated. * src/truetype/ttobjs.h: Updated. * include/freetype/internal/services/svmetric.h (MetricsVariations): Add `size_reset`. (FT_DEFINE_SERVICE_METRICSVARIATIONSREC): Updated. * include/freetype/internal/tttypes.h (TT_FaceRec_): Rename `var` to `tt_var` and add `face_var`. * src/cff/cffdrivr.c (cff_service_metrics_variations): Add `size_reset`. (cff_hadvance_adjust, cff_metrics_adjust): Updated. * src/cff/cffobjs.c (cff_face_init): Use `face_var`. * src/sfnt/sfobjs.c (sfnt_init_face): Initialize `face_var`. * src/sfnt/ttmtx.c (tt_face_get_metrics): Use `tt_var`. * src/truetype/ttgxvar.c (tt_size_reset_iterator): Renamed to... (ft_size_reset_iterator): ... this new function. Call `size_reset`. (tt_apply_mvar): Pass `size_reset` to `ft_size_reset_iterator`. Fixes #1211
Alexei Podtelezhnikov e77d8ba8 2023-04-10T15:17:17 * src/cff/cffcmap.c (cff_cmap_encoding_char_next): Abbreviate.
Alexei Podtelezhnikov 1a4c18f7 2023-04-10T15:30:43 Align `char_next` return types. This is mostly cosmetic because FT_UInt and FT_UInt32 are likely identical. * src/sfnt/ttcmap.c, src/cff/cffcmap.c, src/psaux/t1cmap.c, src/psnames/psmodule.c, include/freetype/internal/service/svpcsmap.h, src/pfr/pfrcmap.c, src/winfonts/winfnt.c (*_char_next): return FT_UInt.
Alexei Podtelezhnikov 4d8db130 2023-03-20T16:53:51 [cff] Simplify `t2_strings` management in the old engine. * src/cff/cffparse.c (cff_parser_run): Allocate the charstring buffers and the list nodes together so that they can be freed at once. (finalize_t2_strings): Removed as no longer needed. (cff_parser_done): Updated.
Alexei Podtelezhnikov 4f0a55d1 2023-03-19T10:13:52 [cff] Rework the stream limit checks. The old stream limit checks, before 6986ddac1ece, were good but pointless for the crafted t2_strings. Checking limits there is not necessary as they are created to hold all data. By using two conditions, we can detect the actual crossing of the stream boundary as appropriate for the stream pointer only. The t2_strings parsing will not be triggering these checks. * src/cff/cffparse.c (cff_parser_within_limits): Removed. (cff_parse_real, cff_parse_integer): Redesign the stream limit check. (cff_parse_num, do fixed, cff_parse_fixed_dynamic): Update callers.

Alexei Podtelezhnikov a2b8937d 2023-03-04T14:00:52 [cff] Clean up memory management in the old engine. * src/cff/cffparse.c (finalize_t2_strings): Fix NULL-dereferencing in the out-of-memory situation, use `FT_FREE`. (cff_parser_run): Use FreeType memory allocation macros and avoid uninitialized pointers.

Alexei Podtelezhnikov 5ac6276a 2023-03-03T17:21:10 [cff,cid,type1] Shorten de-referencing. * src/cff/cffobjs.c (cff_clot_init): Use immediate library reference. * src/cid/cidobjs.c (cid_slot_init): Ditto. * src/type1/t1objs.c (T1_GlyphSlot_Init): Ditto.
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.
Werner Lemberg be724c81 2023-02-07T22:24:53 For debugging, avoid implicit conversion from integer to double. Otherwise we get zillions of clang 15 warnings. * src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c, src/base/ftobjs.c, src/base/ftoutln.c, src/cff/cffparse.c, src/raster/ftraster.c, src/sfnt/pngshim.c, src/truetype/ttgload.c, src/truetype/ttgxvar.c, src/truetype/ttobjs.c, src/type1/t1gload.c: Use `double` cast in debugging and tracing macros.
Werner Lemberg 646cc8ef 2023-02-02T10:38:18 * src/cff/cffgload.c (cff_slot_load): Avoid memory leak. Fixes issue #1204.
Werner Lemberg 65f85237 2023-01-17T09:18:25 Update all copyright notices.
Alexei Podtelezhnikov 1bfaca06 2022-10-21T07:18:06 [cff, truetype] Simplify SVG metrics scaling. Use pre-calculated scaling factors. Also, the advance widths used to be rounded, which was incorrect. * src/cff/cffgload.c (cff_slot_load): Use `x_scale` and `y_scale`. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto.
Werner Lemberg 5182264a 2022-10-10T12:31:53 [cff] Remove `FT_CONFIG_OPTION_NO_GLYPH_NAMES`. This ancient option stayed completely undocumented. Given that the 'cff' driver requires the 'psnames' module, it makes no sense today to have this macro. * src/cff/cffdrivr.c (cff_services), src/cff/cffobjs.c (cff_face_init): Remove corresponding conditional code.

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.

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.
David Turner 4eee1340 2020-05-18T09:16:12 Remove Jamfile files from the tree. These have not been used in a very, very long time, so better remove them. A corresponding patch will be submitted to the `freetype2-demos' repository. * src/Jamfile, src/*/Jamfile, Jamrules: Delete.

Armin Hasitzka 6986ddac 2019-03-31T11:08:49 [cff] Fix boundary checks. 642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically allocated memory when parsing CFF files with the "old" engine. Bounds checks have never been updated, however, leading to pointless comparisons of pointers in some cases. This commit presents a solution for bounds checks in the CFF module with an extended logic for the "old" engine while staying as concise as possible for the "new" one. * src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and the additional field `t2_strings' within `CFF_ParserRec'. * src/cff/cffparse.c (cff_parser_within_limits): Move all boundary checks into this new function and update the rest of `cffparse.c' to use it.

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.
