0f35b042 | 2020-07-06 10:56:36 | [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 | 2020-07-06 10:56:36 | [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 | 2020-07-06 09:21:03 | [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 | 2020-07-02 11:09:57 | [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 | 2020-07-03 22:29:34 | [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 | 2020-07-03 09:17:22 | [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 | 2020-07-03 09:02:09 | [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 | 2020-06-20 05:31:34 | [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 | 2020-06-19 18:55:49 | [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 | 2020-06-19 16:29:07 | [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 | 2020-06-19 16:21:08 | 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 | 2020-06-19 08:39:23 | [base] Rework d1180b5f9598 until further notice. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Reject large outlines. | |
|
8ed5a247 | 2020-06-19 10:35:57 | [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 | 2020-06-19 08:18:26 | [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 | 2020-06-19 05:41:37 | [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 | 2020-06-19 04:14:39 | [sfnt] Support Intel compilers. * src/sfnt/pngshim.c (premultiply_data): Intel compilers do not currently support `__builtin_shuffle'. | |
|
a4429959 | 2020-06-18 15:12:03 | [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 | 2020-06-18 15:12:03 | [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 | 2020-06-19 03:41:12 | * src/cff/cffload.c (cff_index_get_pointers): Rename `t' to `tbl'. | |
|
c8cd139c | 2020-06-18 13:46:37 | [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 | 2020-06-17 15:12:30 | woff2tags.h: Fix copyright year. | |
|
16586859 | 2020-06-13 21:15:45 | 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 | 2020-06-08 13:31:55 | 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 | 2020-06-02 17:14:54 | * src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps. | |
|
4eee1340 | 2020-05-18 09:16:12 | 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 | 2020-05-12 00:38:46 | [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 | 2020-05-11 23:30:37 | [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 | 2020-05-05 20:14:14 | * 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 | 2020-05-08 10:59:37 | * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#58319). The font that exceeds the old limit is Icono Regular, version 1.00000. | |
 |
7a019a63 | 2020-04-04 14:06:37 | [woff2] Return if single stream operation fails. * src/sfnt/sfwoff2.c (get_x_mins): Do it. * src/sfnt/woff2tags.c: Remove unused include. | |
 |
6a431038 | 2020-03-02 18:21:27 | [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 | 2020-02-29 20:18:00 | 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 | 2020-02-28 07:43:00 | [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 | 2020-02-25 11:08:11 | Fix for CFF space glyph regression (#57541). * src/psaux/psft.c (cf2_decoder_parse_substrings): Replace early-out with FT_OFFSET. | |
|
fa147af4 | 2020-02-22 18:30:46 | [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 | 2020-02-21 20:57:52 | [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. | |
 |
49f3394d | 2020-02-19 12:56:49 | [autofit] Add support for Hanifi Rohingya script. * src/autofit/afblue.dat: Add blue zone data for Hanifi Rohingya. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Hanifi Rohingya standard character. * src/autofit/afranges.c, src/autofit/afstyles.h: Add Hanifi Rohingya data. | |
|
8930cc96 | 2020-02-12 18:25:03 | * src/sfnt/ttcmap.c (tt_face_build_cmaps): Ignore version (#57708). | |
|
4a19a53d | 2020-02-04 13:37:19 | * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#57732). The font that exceeds the old limit is Constantine, version 1.001. | |
|

|
fd03cf88 | 2020-01-04 19:28:36 | [base] Fix `FREETYPE_PROPERTIES=type1:hinting-engine=adobe`. * src/base/ftpsprop.c (ps_property_set) [hinting-engine]: Avoid an incorrect return value that caused a warning. The function did the right thing, though. | |
|
a99a8e28 | 2020-01-03 18:09:12 | [woff2] Fix memory leaks and a runtime warning. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=19773 * src/sfnt/sfwoff2.c (compute_ULong_sum): Add missing cast. (reconstruct_hmtx): Add missing deallocation calls. | |

2a23dc7f | 2019-08-14 02:36:27 | [woff2] Support `hmtx' reconstruction when `glyf' is untransformed. `reconstruct_hmtx' requires `info->x_mins' and `info->num_glyphs' to reconstruct the hmtx table. In case glyf is not transformed, we call `get_x_mins' which does the necessary work. * src/sfnt/sfwoff2.c (get_x_mins): New function. (reconstruct_font): Call get_x_mins. | |
|
5367e0ca | 2019-08-05 01:53:00 | [sfnt] Support `face->num_faces' for WOFF2 fonts. Set correct value of `face->num_faces' for WOFF2 fonts. This is being handled separately because we only load the tables for the requested font face in `woff2_open_font' and create a single-face sfnt stream. The full discussion is at: https://lists.gnu.org/archive/html/freetype-devel/2019-08/msg00000.html * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `woff2_num_faces'. (sfnt_init_face): Introduce variable `woff2_num_faces', and change `face->root.num_faces' if `woff2_num_faces' is set. * src/sfnt/sfwoff2.c (woff2_open_font): Validate requested face index and handle negative face indices. * src/sfnt/sfwoff2.h (woff2_open_font): Add parameter `num_faces' to declaration. | |

bb7668d7 | 2019-07-28 19:38:05 | [woff2] Improve memory and error handling. Free up memory after use, and improve error handling. * src/sfnt/sfwoff2.c (reconstruct_font, woff2_open_font): Implement changes. | |
|
1e020768 | 2019-07-18 01:50:16 | [woff2] Avoid too many calls to `FT_REALLOC'. We do this by using `totalSfntSize' as an initial reference, and extending the buffer when required. This reduces rendering time considerably. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add `totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'. * src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep track of and update total size of stream. (WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly. (pad4, store_loca, reconstruct_glyf, reconstruct_hmtx, reconstruct_font): Update parameters to accept `sfnt_size'. (woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field `totalSfntSize' as initial reference (if value makes sense) and allocate `totalSfntSize' bytes for the sfnt stream. `write_buf' handles reallocation if and when required. Also resize the stream to `actual_sfnt_size' after reconstruction. |
