David Turner 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'.
David Turner 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'.
Werner Lemberg 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'.
David Turner 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Sebastian Rasmussen 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.
Sebastian Rasmussen 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.
Sebastian Rasmussen 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.
Sebastian Rasmussen 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.
Alexei Podtelezhnikov 6e722f2e 2020-06-19T08:39:23 [base] Rework d1180b5f9598 until further notice. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Reject large outlines.
Sebastian Rasmussen 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'.
Werner Lemberg 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.
Werner Lemberg 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.
Stephen McDowell d924c5cf 2020-06-19T04:14:39 [sfnt] Support Intel compilers. * src/sfnt/pngshim.c (premultiply_data): Intel compilers do not currently support `__builtin_shuffle'.
Sebastian Rasmussen 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'.
Sebastian Rasmussen 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'.
Werner Lemberg 74cebeae 2020-06-19T03:41:12 * src/cff/cffload.c (cff_index_get_pointers): Rename `t' to `tbl'.
Sebastian Rasmussen 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.
Werner Lemberg 7438235b 2020-06-17T15:12:30 woff2tags.h: Fix copyright year.
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.
Werner Lemberg 9e6e903c 2020-06-02T17:14:54 * src/sfnt/ttcmap.c (tt_face_build_cmaps): Trace number of cmaps.
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.
Alexei Podtelezhnikov 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.
Alexei Podtelezhnikov 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.
Werner Lemberg 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.
Jakub Alba 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.
Nikhil Ramakrishnan 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.
Moazin Khatti 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.
Ben Wagner 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.
Ben Wagner 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.
Dominik Röttsches 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.
Werner Lemberg 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.
Werner Lemberg 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.
Nikolaus Waxweiler 49f3394d 2020-02-19T12:56:49 [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.
Werner Lemberg 8930cc96 2020-02-12T18:25:03 * src/sfnt/ttcmap.c (tt_face_build_cmaps): Ignore version (#57708).
Werner Lemberg 4a19a53d 2020-02-04T13:37:19 * src/truetype/ttinterp.c (TT_RunIns): Adjust loop counter (#57732). The font that exceeds the old limit is Constantine, version 1.001.

Werner Lemberg 60c52f0e 2019-08-27T10:08:01 [woff2] Formatting; some comments.
Nikhil Ramakrishnan 86803acd 2019-08-22T16:46:03 [woff2] Check whether known tag is in array bounds. If table tag is not 0x3f, we expect a value between 0 and 62. If this is not the case, exit with errors. * src/sfnt/sfwoff2/c: Check whether table tag makes sense. * src/sfnt/woff2tags.c: Return 0 if tag is out of bounds.
Nikhil Ramakrishnan d2681a49 2019-08-21T20:21:02 [woff2] More formatting and documentation. * include/freetype/internal/wofftypes.h, src/sfnt/sfwoff2.c: Implement formatting changes suggested as https://lists.nongnu.org/archive/html/freetype-devel/2019-08/msg00052.html
Nikhil Ramakrishnan 1a103015 2019-08-17T14:57:59 * src/sfnt/sfwoff2.c: Improve trace comments. Adjust tracing levels for comments, and more formatting.
Nikhil Ramakrishnan 97616704 2019-08-14T17:39:55 [woff2] Formatting. * src/sfnt/sfobjs.c, src/sfnt/sfwoff2.c: Better formatting.
Nikhil Ramakrishnan 2a23dc7f 2019-08-14T02:36:27 [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.
Nikhil Ramakrishnan 5367e0ca 2019-08-05T01:53:00 [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.
Nikhil Ramakrishnan bb7668d7 2019-07-28T19:38:05 [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.
Nikhil Ramakrishnan 1e020768 2019-07-18T01:50:16 [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.
