907715a6	2022-02-09T07:31:56	Add `FT_FACE_FLAG_SBIX` and `FT_HAS_SBIX`. Fonts with 'sbix' tables need special handling by the application. * include/freetype/freetype.h (FT_FACE_FLAG_SBIX, FT_HAS_SBIX): New macros. * src/sfnt/sfobjs.c (sfnt_load_face): Set `FT_FACE_FLAG_SBIX` if 'sbix' table is present.
06727a52	2022-02-09T08:36:15	* include/freetype/freetype.h (FT_LOAD_SBITS_ONLY): Tag macro as public.
a8e4563c	2022-03-19T23:54:31	Add `FT_FACE_FLAG_SBIX_OVERLAY` and `FT_HAS_SBIX_OVERLAY`. * include/freetype/freetype.h (FT_FACE_FLAG_SBIX_OVERLAY, FT_HAS_SBIX_OVERLAY): New macro. * src/sfnt/ttsbit.c (tt_face_load_sbit): Handle `FT_FACE_FLAG_SBIX_OVERLAY`. Remove obsolete tracing message.
1949a7ec	2022-03-19T18:51:34	Add `FT_PARAM_TAG_IGNORE_SBIX`. This is another bit to handle 'sbix' tables as described in the OpenType specification. * include/freetype/ftparams.h (FT_PARAM_TAG_IGNORE_SBIX): New macro. * src/sfnt/sfobjc.c (is_apple_sbix): Rename to... (has_sbix): ... this. Check for more sbit tables. Handle `FT_PARAM_TAG_IGNORE_SBIX` to eventually control `has_sbix`. Only call sbit table loader if an sbit table is present.
7789f2bb	2022-03-18T15:52:47	[doc] FT_OUTLINE_OVERLAP was introduced in 2.10.3. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): Document when added.
5499d7bf	2022-03-04T16:42:02	* include/freetype/freetype.h: Improve SDF documentation.
01d4deb0	2022-02-16T14:21:00	ftmm.h: Minor documentation improvement.
5a53e51b	2022-02-12T07:58:43	t1tables.h: Documentation improvements.
c67ecb8c	2022-02-12T07:52:57	t1tables.h: Whitespace.

36ee3160	2022-01-31T10:37:56	freetype.h: Minor documentation improvement.
e34a860a	2022-01-27T11:50:12	Document `FT_Outline_Decompose` degenerate segments. `FT_Outline_Decompose` does not filter out and can return degenerate segments in an outline. This can be surprising when attemping to stroke such an outline. Clarify the existing documentation on this matter to cover all forms of degeneracy (without specifying exactly how they will be reported), why they might arise, and better explain in what cases they may be an issue. * include/freetype/ftoutlin.h (FT_Outline_Decompose): update documentation. Fixes #952.
267c6918	2022-01-25T14:46:36	Aarg, typo.

(ft_svg_glyph_init, ft_svg_glyph_done, ft_svg_glyph_copy, ft_svg_glyph_transform, ft_svg_glyph_prepare): New function. (ft_svg_glyph_class): New class. (FT_New_Glyph, FT_Glyph_To_Bitmap): Updated to handle OT-SVG glyphs. * src/base/ftglyph.h: Updated.
f93a897a	2021-12-25T19:20:44	Add code to load OT-SVG glyph documents. * include/freetype/config/ftheader.h (FT_OTSVG_H): New macro. * include/freetype/freetype.h (FT_FACE_FLAG_SVG, FT_HAS_SVG): New macros. (FT_LOAD_SVG_ONLY): New internal macro. * include/freetype/ftimage.h (FT_Glyph_Format): New enumeration value `FT_GLYPH_FORMAT_SVG`. * include/freetype/internal/ftobjs.h (FT_GLYPH_OWN_GZIP_SVG): New macro. * include/freetype/internal/fttrace.h: Add `ttsvg` for `ttsvg.c`. * include/freetype/internal/sfnt.h(load_svg, free_svg, load_svg_doc): New functions. * include/freetype/internal/tttypes.h (TT_FaceRec): Add `svg` for the SVG table. * include/freetype/otsvg.h (FT_SVG_DocumentRec): New structure to hold the SVG document and other necessary information of an OT-SVG glyph in a glyph slot. * include/freetype/tttags.h (TTAG_SVG): New macro. * src/base/ftobjs.c: Include `otsvg.h`.

06c1a25e	2021-12-25T17:59:42	Add flag `FT_CONFIG_OPTION_SVG`. This flag is going to be used to conditionally compile support for OT-SVG glyphs. FreeType will do the parsing and rely on external hooks for rendering of OT-SVG glyphs. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_SVG): New flag.
99a940f8	2022-01-20T15:06:09	* include/freetype/freetype.h: Clarify `FT_Size` life cycle.
054782c4	2022-01-19T22:14:06	[base] Undefined scale means no scale. It might be surprising that FreeType does not have default ppem and the size has to be set explicitly or face undefined behavior with undefined variables and errors. This offers an alternative to missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined behavior is bettr than undefined one. This is alternative to !132 and discussed in https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708 * src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale. * include/freetype/freetype.h: Document it.
3f6497bd	2022-01-15T22:44:28	Add Watcom C/C++ calling. In the unlikely case the source is built with OpenWatcom's -ec? switches to enforce a calling convention, the qsort() compare function must still be set to __watcall. * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): Updated.
11ea89b5	2022-01-14T22:07:44	Add Watcom C/C++ support. * include/freetype/config/integer-types.h: Make sure `long long` is used then available. * include/freetype/internal/ftcalc.h (FT_MSB): Add Watcom C/C++ pragma.
7f7bf6f0	2022-01-14T20:33:28	* include/freetype/internal/compiler-macros.h [FT_COMPARE_DEF]: Tighten. This works around Watcom C library using __watcall.
d0cfb4e1	2022-01-11T10:54:10	Update all copyright notices.
2b672e72	2022-01-02T18:33:03	* builds/unix/configure.raw: Restore `SYSTEM_ZLIB` variable. This was accidentally removed with commit 93ebcbd0 almost eight years ago.
7add5b2b	2021-12-11T22:54:06	[truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records. (tt_face_get_device_metrics): Implement binary search to retrieve advances.
6c831d65	2021-12-11T22:34:27	[truetype] Initialize the loader with `hdmx` data. The `hdmx` matching can be done before the glyph is loaded. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add a field. * src/truetype/ttgload.c (compute_glyph_metrics): Relocate the `hdmx` code from here... (tt_loader_init): ... to here, before the glyph is loaded.
3f83daee	2021-12-01T20:17:59	* Version 2.11.1 released. ========================== Tag sources with `VER-2-11-1'. * docs/VERSION.TXT: Add entry for version 2.11.1. * docs/CHANGES, docs/release: Updated. * README, src/base/ftver.rc, builds/windows/vc2010/index.html, builds/windows/visualc/index.html, builds/windows/visualce/index.html, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/index.html, docs/freetype-config.1: s/2.11.0/2.11.1/, s/2110/2111/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 24:1:18. * CMakeLists.txt (VERSION_PATCH): Set to 1. * builds/toplevel.mk (version_tag, CHANGELOG_SCRIPT): New variables. (do-dist): Generate `ChangeLog` file with all commits since last release.
3cabd142	2021-11-22T19:36:45	Update `CHANGES` files, other minor whitespace and documentation issues.
f8a4163a	2021-11-20T07:01:26	* include/freetype/fttypes.h (FT_MAKE_TAG): Remove the same casting.
8c8f51c5	2021-11-19T21:50:22	Avoid undefined left-shifts. We really have to use double casts to avoid issues with C's and C++'s signedness propagation rules in implicit casts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41178 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41182 * include/freetype/config/public-macros.h (FT_STATIC_CAST, FT_REINTERPRET_CAST): Modify macro to take two arguments. Update all callers. (FT_STATIC_BYTE_CAST): New macro. * include/freetype/freetype.h (FT_ENC_TAG): Use `FT_STATIC_BYTE_CAST`. * include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto. * include/freetype/fttypes.h (FT_MAKE_TAG): Ditto. Use `FT_Tag` for casting. * src/ftraster/ftmisc.h (FT_MAKE_TAG): Removed, no longer needed. (FT_STATIC_BYTE_CAST): New macro. * src/smooth/ftgrays.c (FT_STATIC_CAST): Replace with... (FT_STATIC_BYTE_CAST): ... this.
9079c5d9	2021-11-13T08:53:19	Provide C++ versions for public macros with casts. Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for macros with C-style casts even for system header files; this also affects directories included with `-isystem`. While this could be seen as a problem with g++, the problem is more a philosophical one: Over the time, C and C++ diverged more and more, and some features of C are no longer the 'right' solution in C++. * include/freetype/config/public-macros.h (FT_STATIC_CAST, FT_REINTERPRET_CAST): New macros. * include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_, FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`. Correctly handle negative 'signed char' input. * include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto. * include/freetype/fttypes.h (FT_MAKE_TAG, FT_BOOL): Ditto. * include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): Use `FT_REINTERPRET_CAST`. * src/smooth/ftgrays.c (FT_STATIC_CAST)[STANDALONE_]: New macro. [!STANDALONE]: Include `FT_CONFIG_CONFIG_H`. Fixes #1116.
42e61723	2021-11-11T23:06:36	Explicitly define `FT_MSB` for Clang. * include/freetype/internal/ftcalc.h [__clang__] (FT_MSB): Updated.
188c7d66	2021-11-09T22:47:26	Additional `FT_MSB` macro definitions. Better macros for Windoes CE and ARM in general, based on !109 from metarutaiga. * include/freetype/internal/ftcalc.h [_MSC_VER] (FT_MSB): Updated.
7f4b9bfb	2021-11-07T10:20:16	[dlg] Define DLG_STATIC explicitly. DLG_STATIC is intended to disable Windows DLL linking attributes. It does not hurt to define it explicitly when we wrap DLG code. This fixes tons of LNK4286 and C4273 warnings from MSVC if we forget to define DLG_STATIC as a compiler option. * builds/windows/vc2010/freetype.vcxproj: Remove DLG_STATIC option. * src/dlg/dlgwrap.c [FT_DEBUG_LOGGING]: Define DLG_STATIC. * include/freetype/internal/ftdebug.h [FT_DEBUG_LOGGING]: Ditto.
d3d3ff76	2021-11-01T17:32:27	[sfnt] Clarify `COLR` v1 FT_Paint* format representations * include/freetype/ftcolor.h (FT_PaintLinearGradient, FT_PaintRadialGradient, FT_PaintSweepGradient, FT_PaintTransform, FT_PaintTranslate, FT_PaintScale, FT_PaintRotate, FT_PaintSkew): Clarify 16.16 fixed point representation of struct fields. * src/sfnt/ttcolr.c (read_paint): Shift coordinates for FT_PaintLinearGradient, FT_PaintRadialGradient, FT_PaintSweepGradient accordingly. Fixes: https://gitlab.freedesktop.org/freetype/freetype/-/issues/1110
793c0126	2021-10-27T22:36:11	[woff] Optimize table tagging. * include/freetype/internal/wofftypes.h (WOFF_TableRec): Use 32-bit tag. * src/sfnt/sfwoff.c (woff_open_font): Use 32-bit tag.
a577bbcb	2021-10-27T22:24:27	[woff2] Optimize table tagging. Fixes #1107. * include/freetype/internal/wofftypes.h (WOFF2_TableRec): Use 32-bit tag. * src/sfnt/sfwoff2.c (compare_tags, find_table, woff2_open_font): Use 32-bit tag. * src/sfnt/woff2tags.[ch] (woff2_known_tags): Use static storage and return 32-bit tag.
c71eb22d	2021-10-15T22:18:38	Fix typos in memory macros. FT_QNEW_ARRAY and FT_QRENEW_ARRAY were using the non-Q FT_MEM_NEW_ARRAY and FT_MEM_RENEW_ARRAY. Change these to use the Q versions. Also fix the one issue discovered in tt_face_load_name where table->names is created with FT_QNEW_ARRAY but the extra string member is not initialized to NULL. * include/freetype/internal/ftmemory.h (FT_Q(RE)NEW_ARRAY): Use FT_MEM_Q(RE)NEW_ARRAY as needed. * src/sfnt/ttload.c (tt_face_load_name): Initialize `entry->string`.
3b036820	2021-10-10T23:11:10	[cid] Signedness revisions. Unsigned checks are simpler. * include/freetype/t1tables.h (CID_FaceInfoRec): Change to unsignd `num_dicts`. * src/cid/cidparse.h (CID_Parser): Change to unsigned `num_dict`. * src/cid/cidgload.c (cid_load_glyph): Updated. * src/cid/cidload.c (cid_load_keyword, parse_fd_array, parse_expansion_factor, parse_font_name, cid_read_subrs, cid_face_open): Updated. * src/cid/cidobjs.c (cid_face_done): Updated. * src/cid/cidparse.c (cid_parser_new): Updated.
22befeef	2021-10-07T22:41:56	Signedness revisions. This eliminates explicit casting by switching to unsigned fields. The revisions mostly impact the handling of CID fonts. * include/freetype/fttypes.h (FT_Data): Change to unsigned `length`. * include/freetype/t1tables.h (CID_FaceDictRec): Ditto for `sd_bytes`. (CID_FaceInfoRec): Ditto for `gd_bytes` and `gd_bytes`. * include/freetype/internal/tttypes.h (TT_LoaderRec): Ditto for `byte_len`. * src/cid/cidgload.c (cid_load_glyph): Updated. * src/cid/cidload.h (cid_get_offset): Update argument. * src/cid/cidload.c (cid_get_offset, cid_read_subrs, cid_face_open): Updated. * src/cff/cffgload.c (cff_get_glyph_data, cff_free_glyph_data): Updated. * src/psaux/psft.c (cf2_getT1SeacComponent): Updated. * src/truetype/ttgload.c (TT_Process_Composite_Glyph, load_truetype_glyph): Updated.
bbab0a67	2021-10-04T23:55:46	* include/freetype/internal/ftgloadr.h: Add missing header. Noticed by Jouk Jansen.
311764fa	2021-10-01T11:50:12	Additional `FT_MSB` macro definitions. * include/freetype/internal/ftcalc.h [__DECC,_CRAYC]: Use builtins and intrinsics.
766b2c19	2021-09-24T22:14:22	Propagate sign when reading OFF3. Signed 24-bit values are extremely rare. FreeType only reads them in PFR fonts with bitmap strikes conditionally. They have not been seen in the known fonts. That is why this bug could never be discovered. `FT_FRAME_OFF3` propagates sign correctly. * include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE): Propagate sign into 32-bit value. (FT_GET_OFF3, FT_READ_OFF3): Needed fixing but removed as unused.
a29e0200	2021-09-23T23:10:26	Use NULL for pointers only. * src/bdf/bdflib.c (): Code changes. include/freetype/freetype.h: Comments only. * src/cff/cffload.c, src/cff/cffobjs.c: Ditto. * src/winfonts/winfnt.c: Ditto.

3b573e45	2021-09-22T22:22:13	Reference `fopen` in the docs.
e942a310	2021-09-09T22:17:46	[truetype] Tweak `loca` clamping. Fixes #1095. * src/truetype/ttpload.c (tt_face_load_loca): Fix up clamping. * include/freetype/internal/tttypes.h (TT_Face): Correct docs.
7482c98f	2021-09-01T22:18:29	[base] Clean up stream reading. * src/base/ftstream.c (FT_Stream_ReadUShort, FT_Stream_ReadUOffset, FT_Stream_ReadULong and their LE variants): Remove unnecessary initialization and slightly refactor. (FT_Stream_GetByte, FT_Stream_ReadByte): Rename to return unsigned value and align with sister functions. * include/freetype/internal/ftstream.h (FT_Stream_GetByte, FT_Stream_ReadByte): Update prototypes and caller macros.
78f2bd0b	2021-08-22T22:32:07	Whitespace formatting.
d92aa23f	2021-08-22T13:12:45	Decorate const arguments. * src/base/ftglyph.c (FT_Glyph_Transform, FT_Glyph_To_Bitmap): Do it. * include/freetype/ftglyph.h (FT_Glyph_Transform, FT_Glyph_To_Bitmap): Do it.
ffdac8d6	2021-08-19T20:41:55	Determine `long long` availability based on its size. MSVC, for example, used `long long` even without full C99 support. * include/freetype/config/ftstdlib.h: Check if `long long` limits are defined in <limits.h>. * include/freetype/config/integer-types.h: Check `long long` size and use it to typedef FT_Int64.
02ba0fc8	2021-08-18T23:27:48	Readily use `long long` as a 64-bit type in C99 mode. * include/freetype/config/integer-types.h (FT_INT64): FT_CONFIG_OPTION_FORCE_INT64 is no longer required to use `long long`.
85703839	2021-08-18T23:05:51	Use FT_INT64 instead of FT_LONG64. * include/freetype/config/integer-types.h: Remove synonymous FT_LONG64. * include/freetype/internal/ftcalc.h: s/FT_LONG64/FT_INT64/. * src/base/ftcalc.c: Ditto. * src/base/fttrigon.c: Ditto. * src/smooth/ftgrays.c: Ditto.
f11f3ed1	2021-08-18T06:54:34	[base] Fix ppem size overflow. Fixes #1086. * src/base/ftobjs.c (FT_Request_Metrics): Add return value. Check whether ppem values fit into unsigned short values. (FT_Request_Size): Updated. * include/freetype/internal/ftobjs.h: Updated. * src/cff/cffobjs.c (cff_size_request), src/cid/cidobjs.c (cid_size_request), src/truetype/ttdriver.c (tt_size_request), src/type1/t1objs.c (T1_Size_Request): Updated.
e40ae756	2021-08-09T13:44:55	[sfnt] Add missing blend mode 'plus' to 'COLR' v1. * include/freetype/ftcolor.h (FT_Composite_Mode): Add missing blend mode 'plus' after it was added to the spec.
2c853b38	2021-08-08T00:22:34	include/freetype/freetype.h (FT_Encoding): Improve documentation. Based on a suggestion by Antony Lee <anntzer.lee@gmail.com>.
47cf8ebf	2021-07-28T17:36:57	[sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table. The optional 'COLR' v1 glyph-specific clip box helps upstream graphics libraries allocate a sufficiently large bitmap for a glyph without having to traverse the glyph graph for that. See https://github.com/googlefonts/colr-gradients-spec/issues/251 for background on the introduction of this specification change. * include/freetype/ftcolor.h (FT_ClipBox): New structure. (FT_Get_Color_Glyph_ClipBox): New function declaration. * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_ClipBox_Func): New function type.

f7c6a06c	2021-07-12T13:58:10	Support architectures where `long` is smaller than pointers. I am currently trying to compile FreeType for CHERI-extended ISAs (CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI Clang compiler, not using `uinptr_t` for casts between integers an pointers results in the following `-Werror` build failures: ``` In file included from .../src/truetype/truetype.c:22: .../src/truetype/ttgload.c:1925:22: error: cast from provenance-free integer type to pointer type will give pointer that can not be dereferenced [-Werror,-Wcheri-capability-misuse] node->data = FT_UINT_TO_POINTER( glyph_index ); ^ .../include/freetype/internal/compiler-macros.h:79:34: note: expanded from macro 'FT_UINT_TO_POINTER' ``` * include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER): The ISO C standard compliant fix for this would be to use `uintptr_t` from `stdint.h`, but I am not sure if this is supported by the minimum compiler version. Therefore, use the compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and Clang since about 3.0) before checking for `_WIN64` and falling back to `unsigned long`.
5d27b10f	2021-07-13T10:59:32	[base] Fix `FT_Open_Face`'s handling of user-supplied streams. This was already true (though undocumented) most of the time, but not if `FT_NEW` inside `FT_Stream_New` failed or if the `FT_OPEN_XXX` flags were bad. Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the user-supplied stream unchanged, and in case of any subsequent error in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`. Up to now, however, `FT_Stream_New` allocates a new stream even if it is already given one by the user. If this allocation fails, the user-supplied stream is not returned to `FT_Open_Face` and never closed. Moreover, the user cannot detect this situation: all they see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that can also happen after a different allocation fails within the main body of `FT_Open_Face`, when the user's stream has already been closed by `FT_Open_Face`. It is plausible that the user stream's `close` method frees memory allocated for the stream object itself, so the user cannot defensively free it upon `FT_Open_Face` failure lest it ends up doubly freed. All in all, this ends up leaking the memory/resources used by user's stream. Furthermore, `FT_Stream_New` simply returns an error if the `FT_OPEN_XXX` flags are unsupported, which can mean either an invalid combination of flags or a perfectly innocent `FT_OPEN_STREAM` on a FreeType build that lacks stream support. With this patch, the user-supplied stream is closed even in these cases, so the user can be sure that if `FT_Open_Face` failed, the stream is definitely closed. * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer unnecessarily. Move error-handling code to make the control flow more obvious. Close user-supplied stream if the flags are unsupported. `FT_Stream_Open` always sets `pathname.pointer`, so remove the redundant (re)assignment. None of the `FT_Stream_Open...` functions uses `stream->memory`, so keep just one assignment at the end, shared among all possible control flow paths. ('Unsupported flags' that may need a stream closure can be either an invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean `FT_OPEN_STREAM` flag on a FreeType build that lacks stream support.)
a4c8f21a	2021-07-13T10:44:38	[base] Reject combinations of incompatible `FT_OPEN_XXX` flags. The three modes are mutually exclusive, and the documentation of the `FT_OPEN_XXX` constants notes this. However, there was no check to validate this in the code, and the documentation on `FT_Open_Args` claimed that the corresponding bits were checked in a well-defined order, implying it was valid (if useless) to specify more than one. Ironically, this documented order did not agree with the actual code, so it could not be relied upon; hopefully, nobody did this and nobody will be hurt by the new validation. Even if multiple mode bits were allowed, they could cause memory leaks: if both `FT_OPEN_STREAM` and `stream` are set along with either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New` allocated a new stream but `FT_Open_Face` marked it as an 'external' stream, so the stream object was never released. * src/base/ftobjs.c (FT_Stream_New): Reject incompatible `FT_OPEN_XXX` flags.
e592982a	2021-07-13T10:00:22	[sdf] Improve documentation.
205d1ae4	2021-07-12T22:03:25	Small clean-ups for the last few commits. * include/freetype/fttrace.h (afwarp): Removed.
2f11522a	2021-06-02T19:05:09	Remove experimental auto-hinting 'warp' mode. This feature was always experimental, and probably nevery worked properly. This patch completely removes it from the source code, except for a documentation block describing it for historical purpose.
15e88980	2021-06-02T18:54:41	Remove experimental "Latin2" writing system (FT_OPTION_AUTOFIT2) This code has always been experimental and was never compiled anyway (FT_OPTION_AUTOFIT2 does not appear in ftoption.h or even any of our build files).

ff407765	2021-06-25T09:19:51	[base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro. (FT_LOG): Use it to add the trace level to the logging tag. * include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH): Adjust. * docs/DEBUG: Updated.

2b1d5562	2021-06-08T08:29:34	[sdf] Use 8 bits for final SDF output instead of 16bits. Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer.

The specification was updated to have sibling formats, variable and non-variable variants for each. Reflect that here. * sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as the non-variable formats no longer have them.
d51452e3	2021-02-13T08:52:58	Add new function `FT_Get_Transform`. See https://github.com/harfbuzz/harfbuzz/issues/2428 for some reasons to introduce this function. * include/freetype/freetype.h, src/base/ftobjs.c (FT_Get_Transform): Implement it.

(FT_OpaquePaint): Additional tracking field to denote whether root transform is to be returned. * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_Paint_Func): Propagate additional argument. * src/base/ftobjs.c (FT_Get_Color_Glyph_Paint): Ditto. * src/sfnt/ttcolr.c (tt_face_get_colr_glyph_paint): Return root transform reflecting the size and tranform configured on FT_Face. (read_paint): Initialize and track status of insert_root_transform flag.
324612ce	2021-01-31T14:28:44	Always provide logging API. It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to modify `ftexport.sym` conditionally. Problem reported by Alexei. * src/base/ftdebug.c: Include `ftlogging.h`. (FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler, FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.

This is intended to be a temporary solution until 'COLR' v1 support is released in a FreeType version and such a check can be made by using the version number instead.
d3e95d97	2020-12-16T17:12:30	[sfnt] Register 'COLR' v1 API in driver (#59703). * include/freetype/internal/sfnt.h (TT_Get_Color_Glyph_Paint_Func, TT_Get_Paint_Layers_Func, TT_Get_Colorline_Stops_Func, TT_Get_Paint_Func): New function pointer types.

Document `FT_Outline_Decompose` degenerate segments. `FT_Outline_Decompose` does not filter out and can return degenerate segments in an outline. This can be surprising when attemping to stroke such an outline. Clarify the existing documentation on this matter to cover all forms of degeneracy (without specifying exactly how they will be reported), why they might arise, and better explain in what cases they may be an issue. * include/freetype/ftoutlin.h (FT_Outline_Decompose): update documentation.

[base] Undefined scale means no scale. It might be surprising that FreeType does not have default ppem and the size has to be set explicitly or face undefined behavior with undefined variables and errors. This offers an alternative to missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined behavior is bettr than undefined one. This is alternative to !132 and discussed in https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708 * src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale. * include/freetype/freetype.h: Document it.

Add Watcom C/C++ calling. In the unlikely case the source is built with OpenWatcom's -ec? switches to enforce a calling convention, the qsort() compare function must still be set to __watcall. * include/freetype/internal/compiler-macros.h (FT_COMPARE_DEF): Updated.

[truetype] Binary search through the `hdmx` records. The `hdmx` table is supposed to be sorted by ppem size, which enables binary search. We also drop the check for the sufficient length of the record because it is now enforced when the table is loaded. * include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx` record pointers sorted by ppem instead of ppem's themselves. * src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records.

2021-11-19T21:50:22

Avoid undefined left-shifts. We really have to use double casts to avoid issues with C's and C++'s signedness propagation rules in implicit casts. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41178 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=41182 * include/freetype/config/public-macros.h (FT_STATIC_CAST, FT_REINTERPRET_CAST): Modify macro to take two arguments.

Provide C++ versions for public macros with casts. Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for macros with C-style casts even for system header files; this also affects directories included with `-isystem`. While this could be seen as a problem with g++, the problem is more a philosophical one: Over the time, C and C++ diverged more and more, and some features of C are no longer the 'right' solution in C++. * include/freetype/config/public-macros.h (FT_STATIC_CAST, FT_REINTERPRET_CAST): New macros. * include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_, FT_LOAD_TARGET_MODE): Use `FT_STATIC_CAST`. Correctly handle negative 'signed char' input. * include/freetype/ftimage.h (FT_IMAGE_TAG): Ditto. * include/freetype/fttypes.h (FT_MAKE_TAG, FT_BOOL): Ditto. * include/freetype/ftmodapi.h (FT_FACE_DRIVER_NAME): Use `FT_REINTERPRET_CAST`. * src/smooth/ftgrays.c (FT_STATIC_CAST)[STANDALONE_]: New macro.

Propagate sign when reading OFF3. Signed 24-bit values are extremely rare. FreeType only reads them in PFR fonts with bitmap strikes conditionally. They have not been seen in the known fonts. That is why this bug could never be discovered. `FT_FRAME_OFF3` propagates sign correctly. * include/freetype/internal/ftstream.h (FT_PEEK_OFF3, FT_PEEK_OFF3_LE): Propagate sign into 32-bit value.

[sfnt] Add API for retrieving a 'COLR' v1 'ClipBox' table. The optional 'COLR' v1 glyph-specific clip box helps upstream graphics libraries allocate a sufficiently large bitmap for a glyph without having to traverse the glyph graph for that. See https://github.com/googlefonts/colr-gradients-spec/issues/251 for background on the introduction of this specification change. * include/freetype/ftcolor.h (FT_ClipBox): New structure.

Support architectures where `long` is smaller than pointers. I am currently trying to compile FreeType for CHERI-extended ISAs (CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI Clang compiler, not using `uinptr_t` for casts between integers an pointers results in the following `-Werror` build failures: ``` In file included from .../src/truetype/truetype.c:22: .../src/truetype/ttgload.c:1925:22: error: cast from provenance-free integer type to pointer type will give pointer that can not be dereferenced [-Werror,-Wcheri-capability-misuse] node->data = FT_UINT_TO_POINTER( glyph_index ); ^ .../include/freetype/internal/compiler-macros.h:79:34: note: expanded from macro 'FT_UINT_TO_POINTER' ``` * include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER): The ISO C standard compliant fix for this would be to use `uintptr_t` from `stdint.h`, but I am not sure if this is supported by the minimum compiler version. Therefore, use the compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and Clang since about 3.0) before checking for `_WIN64` and falling back to `unsigned long`.

2021-07-13T10:59:32

[base] Fix `FT_Open_Face`'s handling of user-supplied streams. This was already true (though undocumented) most of the time, but not if `FT_NEW` inside `FT_Stream_New` failed or if the `FT_OPEN_XXX` flags were bad. Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the user-supplied stream unchanged, and in case of any subsequent error in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`. Up to now, however, `FT_Stream_New` allocates a new stream even if it is already given one by the user. If this allocation fails, the user-supplied stream is not returned to `FT_Open_Face` and never closed. Moreover, the user cannot detect this situation: all they see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that can also happen after a different allocation fails within the main body of `FT_Open_Face`, when the user's stream has already been closed by `FT_Open_Face`. It is plausible that the user stream's `close` method frees memory allocated for the stream object itself, so the user cannot defensively free it upon `FT_Open_Face` failure lest it ends up doubly freed. All in all, this ends up leaking the memory/resources used by user's stream. Furthermore, `FT_Stream_New` simply returns an error if the `FT_OPEN_XXX` flags are unsupported, which can mean either an invalid combination of flags or a perfectly innocent `FT_OPEN_STREAM` on a FreeType build that lacks stream support. With this patch, the user-supplied stream is closed even in these cases, so the user can be sure that if `FT_Open_Face` failed, the stream is definitely closed. * src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer unnecessarily. Move error-handling code to make the control flow more obvious. Close user-supplied stream if the flags are unsupported. `FT_Stream_Open` always sets `pathname.pointer`, so remove the redundant (re)assignment. None of the `FT_Stream_Open...` functions uses `stream->memory`, so keep just one assignment at the end, shared among all possible control flow paths. ('Unsupported flags' that may need a stream closure can be either an invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean `FT_OPEN_STREAM` flag on a FreeType build that lacks stream support.)

[base] Reject combinations of incompatible `FT_OPEN_XXX` flags. The three modes are mutually exclusive, and the documentation of the `FT_OPEN_XXX` constants notes this. However, there was no check to validate this in the code, and the documentation on `FT_Open_Args` claimed that the corresponding bits were checked in a well-defined order, implying it was valid (if useless) to specify more than one. Ironically, this documented order did not agree with the actual code, so it could not be relied upon; hopefully, nobody did this and nobody will be hurt by the new validation. Even if multiple mode bits were allowed, they could cause memory leaks: if both `FT_OPEN_STREAM` and `stream` are set along with either `FT_OPEN_MEMORY` or `FT_OPEN_PATHNAME`, then `FT_Stream_New` allocated a new stream but `FT_Open_Face` marked it as an 'external' stream, so the stream object was never released. * src/base/ftobjs.c (FT_Stream_New): Reject incompatible `FT_OPEN_XXX` flags.

[base] Add trace level to logging output. Some practical debugging work has shown that displaying level X of an `FT_TRACEX` macro in the output of `FT2_DEBUG="... -v"` would be very helpful to find out which trace level should be selected. As an example, we now get output like ``` [ttobjs:2] TTF driver [ttobjs:2] SFNT driver [sfobjs:2] not a font using the SFNT container format [t1objs:2] Type 1 driver [stream:7] FT_Stream_EnterFrame: 14 bytes ``` * include/freetype/internal/ftdebug.h (FT_LOGGING_TAGX): New macro.

[sdf] Formatting and improved comments.

[sdf] Use 8 bits for final SDF output instead of 16bits. Since 8-bits is enough to represent SDF data we no longer require 16-bits for this purpose. Also, we now normalize the output data to use the entire 8-bit range efficiently. For example: if we use 3.5 format with a spread of 1 we basically only use the starting 5-bits. By normalizing we can use the entire 8-bit range. * include/freetype/freetype.h (FT_Render_Mode): Updated description for `FT_RENDER_MODE_SDF` regarding this change. * include/freetype/ftimage.h (FT_Pixel_Mode): Removed `FT_PIXEL_MODE_GRAY16` since no longer required. * include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer required. * src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit bitmap instead of 16-bit buffer. * src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert 16.16 distance value to our desired format. * src/sdf/ftsdf.c (sdf_generate_with_overlaps, sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function and also use 8-bit output buffer. * src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead of 16-bit buffer.

[sfnt] Update paint format values to support non-variable paints. * freetype.h (FT_PaintFormat): Update paint format identifiers after a specification change. The specification was updated to have sibling formats, variable and non-variable variants for each. Reflect that here. * sfnt/ttcolr.c (read_paint): Remove parsing of variable indices as the non-variable formats no longer have them.

Always provide logging API. It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to modify `ftexport.sym` conditionally. Problem reported by Alexei. * src/base/ftdebug.c: Include `ftlogging.h`. (FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler, FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.

Add config option to test for 'COLR' v1 support in headers. * include/freetype/config/ftoption.h (TT_SUPPORT_COLRV1): New macro so that clients can test whether the FreeType checkout that they are building against supports the 'COLR' v1 API. This is intended to be a temporary solution until 'COLR' v1 support is released in a FreeType version and such a check can be made by using the version number instead.
