804e625d	2020-10-28T13:34:52	[truetype] Minor update to forthcoming OpenType 1.8.4 standard. * src/truetype/ttgxvar.c (ft_var_load_item_variation_store): Limit size of `regionCount`.
007c109b	2020-10-23T08:29:14	* src/sfnt/pngshim.c (Load_SBit_Png): Fix memory leak (#59322). The issue is that `rows` is allocated but will not be freed in the event that the call to `png_read_image` fails and calls `longjmp`.

c9f588be	2020-10-10T12:48:18	Document changes to last release.
40479fad	2020-09-25T17:44:00	[autofit] Synchronize with ttfautohint. This corresponds to the following commits in the ttfautohint git repository: bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting. d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script. * src/autofit/afblue.dat: Add blue zone data for Medefaidrin. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Medefaidrin standard characters. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin data.
e8ee98e6	2020-09-25T07:22:08	Move `scripts/make_distribution_archives.py` to `src/tools`. * scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR, _SCRIPT_DIR): Updated to new location. (main): s/shutils.copyfile/shutils.copy/ to preserve file permissions. (main): Prefix source file paths with `git_dir` while copying files to allow calls of the script from other places than the top-level directory.
4f13a43a	2020-09-24T09:35:24	* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>.
bed960d9	2020-09-24T09:31:56	* src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics.
20186d1b	2020-09-11T23:47:54	[raster] Improve the second pass (#58373). Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only.
c3721642	2020-09-11T23:13:02	[raster] Tune SMART macro (#58352). Windows seems to perform smart dropout control at 26.6 precision. To mimick Windows independent of increased precision, we need to tweak the macro so that some close calls break down rather than up. * src/raster/ftraster.c (SMART): Tweak the macro.
cb473313	2020-09-08T22:41:53	[raster] Introduce SMART macro. * src/raster/ftraster.c (SMART): New macro for smart dropout rounding. (Verstical_Sweep_Drop, Horizontal_Sweep_Drop): Use it.
3594eaee	2020-09-08T22:20:11	[raster] Improve tracing.
600d59e3	2020-09-02T15:48:03	[truetype] Reduce Infinality footprint (cont'd). * src/truetype/ttinterp.c (Ins_DELTAP): Shrink variable scope. (Ins_SHPIX, Ins_MIRP): Revise if-logic.
51a5e338	2020-09-02T00:02:28	[truetype] Reduce Infinality footprint. * src/truetype/ttinterp.c (Ins_SHPIX, Ins_MSIRP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Shrink variable scopes and consolidate ifdefs.
e6c7e4b4	2020-09-01T21:49:52	[truetype] Refactor compensation color. * src/truetype/ttinterp.h (TT_Round_Func): Change the last argument. * src/truetype/ttinterp.c (Ins_ROUND, Ins_NROUND, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Move compensation retrieval from here... (Round_): ... to here. src/truetype/ttobjs.c (tt_size_init_bytecode): Reserve zero compensation at color index 3.
16ee2a22	2020-08-28T23:08:42	[smooth] Don't set target in direct mode. * src/smooth/ftsmooth.c (ft_smooth_raster_overlap): Remove assignment. (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Ditto.
6730854c	2020-08-25T23:16:27	* src/smooth/ftsmooth.c (ft_smooth_raster_overlap): Limit width. Segmentation fault reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=24729
cdc009c2	2020-08-22T13:30:11	* src/truetype/ttgload.c (TT_Get_VMetrics): Add tracing message.
f9f6adb6	2020-08-05T08:24:15	[truetype] Retain OVERLAP_SIMPLE and OVERLAP_COMPOUND. For glyphs with OVERLAP_SIMPLE or OVERLAP_COMPOUND, set FT_OUTLINE_OVERLAP to render them with direct oversampling, which mitigates artifacts (see 3bb512bc9f62). * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): Redefine to rhyme with OVERLAP_SIMPLE. * src/base/ftgloadr.c (FT_GlyphLoader_Rewind): Reset outline flags. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Retain OVERLAP_SIMPLE. (load_truetype_glyph): Retain OVERLAP_COMPOUND.
3a1f4b7a	2020-08-04T22:17:05	* src/truetype/ttgload.c (TT_Load_Glyph): More tracing.
53be1753	2020-07-28T07:33:40	Fix `-Wformat' compiler warnings. * src/: Fix format specifiers. builds/unix/ftsystem.c (FT_Stream_Open): Ditto.
8cfc41ae	2020-07-25T12:23:22	Fix `-Wformat' compiler warnings. Problem reported by Priyesh kumar <priyeshkkumar@gmail.com> * src/base/ftoutln.c (FT_Outline_Decompose): Fix number of arguments to tracing macro. * src/bdf/bdfdrivr.c (bdf_cmap_char_next, bdf_get_bdf_property): Ditto. * src/cache/ftcbasic.c (ftc_basic_family_get_count): Ditto. Reformulate message. * src/pcf/pcfdrivr.c (pcf_get_bdf_property): Ditto. * src/sfnt/sfwoff2.c (woff2_open_font): Ditto. Trace table offset, too. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Ditto.
b6183ea3	2020-07-23T13:03:22	* src/sfnt/sfwoff2.c (woff2_decompress): Fix compiler warning. Reported by Hin-Tak.
96fb73ef	2020-07-07T16:58:14	Fix clang warnings. * include/freetype/internal/autohint.h (FT_DECLARE_AUTOHINTER_INTERFACE): New macro. * src/autofit/afmodule.h: Use it to declare `af_autofitter_interface'. * include/freetype/internal/ftobjs.h (FT_DECLARE_GLYPH): New macro. * src/base/ftbase.h: Use it to declare `ft_bitmap_glyph_class' and `ft_outline_glyph_class'. * src/base/ftglyph.c: Include `ftbase.h'. * src/cff/cffparse.c (cff_parser_run): Fix type of `t2_size'. * src/pcf/pcfdrivr.c (pcf_cmap_char_next): Fix type of `result'. * src/psaux/psauxmod.c (psaux_module_class): Use `FT_DEFINE_MODULE'. * src/psaux/psauxmod.h: Declare `afm_parser_funcs', `t1_cmap_classes', `cff_decoder_funcs', and `psaux_module_class'. * src/pshinter/pshmod.c: Include `pshmod.h'. * src/sfnt/sfwoff2.c (ROUND4, WRITE_SHORT): Fix implicit sign conversion. (compute_ULong_sum): Fix return type. Fix implicit sign conversion. (store_points): Fix type of `last_flag', `repeat_count', and `flag'. Use casts to avoid warnings. (reconstruct_glyf): Fix implicit sign conversion. Use cast to avoid warning. (get_x_mins): Fix implicit sign conversion. * src/sfnt/ttcmap.c: Undef `TTCMAPCITEM'. * src/sfnt/ttcmap.h: Define `TTCMAPCITEM' and include `ttcmapc.h' to declare cmap classes. * src/smooth/ftsmooth.c (ft_smooth_overlap_spans): Use cast. * src/truetype/ttinterp.c (Ins_MIAP): Fix typo.
0f35b042	2020-07-06T10:56:36	[build] Really fix multi and C++ builds. The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++. (FT_UNUSED): Define here instead of... * include/freetype/config/compiler-macros.h: ... here. (FT_FUNCTION_DECLARATION): Remove special definition for C++. (FT_LOCAL_ARRAY_DEF): Fix definition. * src/cache/ftccback.h, src/lzw/ftzopen.h, src/gxvalid/gxvmort.h, src/gxvalid/gxvmorx.h: Add `FT_BEGIN_HEADER' and `FT_END_HEADER'.
cb4a943b	2020-07-06T10:56:36	[build] Fix multi and C++ builds. The following builds were failing due to previous changes: make multi make multi CC="c++" * include/freetype/config/ftconfig.h: Remove `FT_END_HEADER'. * include/freetype/config/ftheader.h (FT_BEGIN_HEADER, FT_END_HEADER): Protect against redefinition. * src/cache/ftccache.h, src/cache/ftcmru.h, src/pcf/pcfutil.h, src/psaux/pserror.h, src/psaux/psft.h, src/psaux/psstack.h, src/sfnt/woff2tags.h: Include `compiler-macros.h'. * src/sfnt/woff2tags.c: Include `woff2tags.h'.
2eb8f886	2020-07-06T09:21:03	[psaux] Improve `t1_decoder_parse_metrics' (#58646). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function to handle `op_callsubr' and `op_return'.
bb66c8d8	2020-07-02T11:09:57	[build] Split off more stuff from `ftconfig.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions required by the FreeType API headers to... * include/freetype/config/public-macros.h: ...this new file. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off macro definitions used by the library but not to be exposed to clients to... * include/freetype/config/compiler-macros.h: ...this new file. * include/freetype/internal/*.h, src/raster/ftraster.h: Include `compiler-macros.h' where needed.
3bb512bc	2020-07-03T22:29:34	[smooth] Introduce direct oversampling for overlaps. This implements oversampling to metigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them.
19d39f43	2020-07-03T09:17:22	[smooth] Use direct rendering mode in Harmony. Instead of rendering 3 bitmaps side by side and reshuffling, we use direct rendering to deliver the bitmaps on each third byte. * src/smooth/ftsmooth.c (ft_smooth_raster_lcd) [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Set up direct mode with... (ft_smooth_lcd_spans): ... new span function.
2d67511a	2020-07-03T09:02:09	[smooth] Separate LCD paths from gray rendering. This makes `ft_smooth_render' a lot smaller and easier to follow. It also cleanly separates Harmony and ClearType-style LCD rendering algorithms. Now I only wish to move LCD filtering and geometry from FT_Library to FT_Renderer. * src/smooth/ftsmooth.c (ft_smooth_render): Move LCD code from here... (ft_smooth_raster_lcd, ft_smooth_raster_lcdv): ... to here. [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Reorganize #ifdef's.
a4434747	2020-06-20T05:31:34	[cff] Fix handling of `style_name == NULL' (#58630). * src/cff/cffobjs.c (cff_face_init): If a call to `cff_strcpy' fails by returning NULL in `cff_face_init', `remove_style' is still called. This means that the NULL pointer is dereferenced, causing a crash.
f594ffdc	2020-06-19T18:55:49	[cff] Fix another two memory leaks (#58629). * src/cff/cffobjs.c (cff_size_init): If a call to `funcs->create' fails to allocate one of the `internal->subfont' variables, make sure to free `internal->topfont' and any successfully allocated subfonts.
2e2f3cb5	2020-06-19T16:29:07	[psaux] Fix memory leak (#58626). * src/psaux/psstack.c (cf2_stack_init): If `cf2_stack_init' fails to allocate the stack, return error early.
09b98060	2020-06-19T16:21:08	Fix memory leak (#58624). * src/base/ftobjs.c (FT_New_Size): Avoid trying to free `size->internal`, unless `size' has been allocated. This mistake appeared in the fix for 58611.
6e722f2e	2020-06-19T08:39:23	[base] Rework d1180b5f9598 until further notice. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Reject large outlines.
8ed5a247	2020-06-19T10:35:57	[cff, cid] Fix segfaults in case of error (#58621). * src/cff/cffobjs.c (cff_slot_done), src/cid/cidobjs.c (cid_slot_done): If `ft_glyphslot_init' fails to allocate `internal', then the class' `done_slot' callback (called by `ft_glyphslot_done') must not dereference the pointer to `internal'.
d1180b5f	2020-06-19T08:18:26	[base] Fix UBSAN error. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23166 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Avoid values larger than 32 bits.
4d364b68	2020-06-19T05:41:37	[woff2] Fix segfault. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=23402 * src/sfnt/sfwoff2.c (get_x_mins): Check whether `loca' table exists.
d924c5cf	2020-06-19T04:14:39	[sfnt] Support Intel compilers. * src/sfnt/pngshim.c (premultiply_data): Intel compilers do not currently support `__builtin_shuffle'.
a4429959	2020-06-18T15:12:03	[base] Fix memory leak (#58611). * src/base/ftobjs.c (FT_New_Size): When the call to `clazz->init_size' fails, make sure to free `size->internal'.
575b78d9	2020-06-18T15:12:03	[cff] Fix memory leak (#58610). * src/cff/cffobjs.c (cff_size_init): When the call to `funcs->create' fails, make sure to free `internal'.
74cebeae	2020-06-19T03:41:12	* src/cff/cffload.c (cff_index_get_pointers): Rename `t' to `tbl'.
c8cd139c	2020-06-18T13:46:37	[cff] Free table upon error allocating other data (#58609). * src/cff/cffload.c (cff_index_get_pointers): When new_bytes fails to allocate, make sure to free the table. Do the same for both allocations if there is a later error.
7438235b	2020-06-17T15:12:30	woff2tags.h: Fix copyright year.
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'.
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.
9e6e903c	2020-06-02T17:14:54	* src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps.
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.
3f70e6d2	2020-05-12T00:38:46	[smooth] Turn on LCD filtering during FreeType initialization. * src/smooth/ftsmooth.c (ft_smooth_init): Enable LCD filtering. * include/freetype/ftlcdfil.h: Document it, remove patent warnings. * include/freetype/freetype.h (FT_Render_Mode): Updated. * include/freetype/config/ftoption.h, devel/ftoption.h [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Do not mention patents.
652f8863	2020-05-11T23:30:37	[smooth] Stop using dedicated LCD modules and classes. The LCD modules were never truly independent. They mostly served as a way to disable patented LCD rendering, which is no longer necessary. The `smooth' module now handles LCD modes as well. * src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class. ft_smooth_lcdv_renderer_class): Deleted. (ft_render_smooth): Reworked from `ft_render_smooth_generic'. * src/smooth/ftsmooth.h: Remove dedicated LCD classes. * src/smooth/module.mk: Remove dedicated LCD modules. * include/freetype/config/ftmodule.h: Ditto. * builds/amiga/include/config/ftmodule.h: Ditto. * include/freetype/ftmodapi.h: Do not mention LCD modules.
132f19b7	2020-05-05T20:14:14	* Version 2.10.2 released. ========================== Tag sources with `VER-2-10-2'. * docs/VERSION.TXT: Add entry for version 2.10.2. * README, Jamfile (RefDoc), 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/2.10.1/2.10.2/, s/2101/2102/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 2. * builds/unix/configure.raw (version_info): Set to 23:2:17. * CMakeLists.txt (VERSION_PATCH): Set to 2. * docs/CHANGES: Updated.
a45da253	2020-05-08T10:59:37	* src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000.
7a019a63	2020-04-04T14:06:37	[woff2] Return if single stream operation fails. * src/sfnt/sfwoff2.c (get_x_mins): Do it. * src/sfnt/woff2tags.c: Remove unused include.
6a431038	2020-03-02T18:21:27	[gzip] Support `gzip' encoded header conditionally. In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used. Problem report in https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html * src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to `inflateInit2' depending on whether the system installation is being used or the internal copy.
11975fe9	2020-02-29T20:18:00	Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure.
216e0776	2020-02-28T07:43:00	[truetype] Add better checks for loading `gvar' table (#57905). * src/truetype/ttgxvar.c (ft_var_load_gvar): Delay settings of any `blend->xxxcount' values until the corresponding data has been checked. Also do some sanitizing to avoid a too early exit. (TT_Vary_Apply_Glyph_Deltas): Improve tracing message.
5b1a37af	2020-02-25T11:08:11	Fix for CFF space glyph regression (#57541). * src/psaux/psft.c (cf2_decoder_parse_substrings): Replace early-out with FT_OFFSET.
fa147af4	2020-02-22T18:30:46	[woff2] Fix font table access. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=20778 * src/sfnt/sfwoff2.c (get_x_mins): Explicitly check for presence of `head' table, which might not have been processed yet.
6e49dff0	2020-02-21T20:57:52	[psaux] Make `t1_decoder_parse_metrics' handle `op_div' (#57519). * src/psaux/t1decode.c (t1_decoder_parse_metrics): Copy corresponding code from old engine's `t1_decoder_parse_charstrings' function.

* src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`. Towards the end of the the function there is a call to `FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units. That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY` is left alone, and is not scaled. Patch from Eric Muller <emuller@amazon.com>.

[raster] Improve the second pass (#58373). Besides dropout control the second horizontal sweep is supposed to clean up straight horizontal edges that are mishandled by the first vertical sweep when a line passes through pixel centers. This line would present as perfectly aligned span edges in the second sweep. * src/raster/ftraster.c (Horizontal_Sweep_Span): Replace the old implementation with a better one focusing on aligned span edges only.

[build] Really fix multi and C++ builds. The following builds were still failing due to previous changes: make multi make multi CC="c++" make CC="c++" This patch fixes the issues, which were missing includes to get the right macro definitions in multi-build mode. Also, `FT_UNUSED' is actually used by third-party code, so move it back to `public-macros.h' to avoid breaking it. * include/freetype/config/public-macros.h (FT_EXPORT): Remove special definition for C++.

[smooth] Introduce direct oversampling for overlaps. This implements oversampling to metigate artifacts in pixels partially covered by overlapping contours. It turns out that the 4x4 oversampling is sufficient but, at least, quadruples the rendering time. The outline has to set FT_OUTLINE_OVERLAP to use this method. * include/freetype/ftimage.h (FT_OUTLINE_OVERLAP): New flag. * src/smooth/ftsmooth.c (ft_smooth_render): Check it to... (ft_smooth_raster_overlap): ... inflate outline and set up direct rendering for oversampling with... (ft_smooth_overlap_spans): ... new span function that integrates them.

[gzip] Support `gzip' encoded header conditionally. In order to support `gzip' encoded header the call to `inflateInit2' was modified in commit 6a92b1fadde26477a9179. However, this code breaks with the outdated internal version of zlib. This is a temporary fix to conditionally support `gzip' encoded header whenever a system installation of zlib is being used.

Fix state of `FT_Face' for buggy `gvar' tables (#57923). By resetting the blend as implemented with this commit fonts with invalid `gvar' tables may keep calling into `ft_var_load_gvar' from `tt_set_mm_blend' and failing, but the font was invalid anyway and we want to keep seeing the failure in `tt_set_mm_blend'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of offset array once. Allocate arrays after `FT_FRAME_ENTER' (extra check before allocating and avoid needing to free array later if error entering frame). Always call `FT_FRAME_EXIT'. Consistently set counts immediately after array initialized. Reset the blend (particularly `blend->glyphoffsets') on failure.
