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.

Alexei Podtelezhnikov 9c850f56 2020-05-01T22:30:15 [builds/unix] Consolidate marco overrides (for the demos to see them). * builds/unix/unix-cc.in (FT_CONFIG_MODULES_H, FT_CONFIG_OPTIONS_H): Override them here... * builds/freetype.mk: ... instead of here.
Werner Lemberg d7994631 2020-04-30T08:37:16 Grammar fix for last commit.
Werner Lemberg e6ecce9a 2020-04-30T07:27:28 CHANGES: We are going to remove Jam.
Werner Lemberg 11beee85 2020-04-08T09:05:32 Allow setting `CC' in Unix build (#58051). * builds/unix/unix-cc.in (CC): Use `override'. The command line value of `CC' (if any) is stored already in `CCraw'.

Nikhil Ramakrishnan 13c0df80 2020-03-22T23:29:51 [docs] Fix building docs if `srcdir' != `builddir'. `docs/reference/*' was moved one directory up in commit 237fed6. * builds/unix/unix-def.in (PIP): Remove variable. * configure: Create `docs' directory and copy assets from `docs/markdown'. * docs/README: Output directory is `reference'.
Nikhil Ramakrishnan 1fd31487 2020-03-21T20:17:17 [docwriter] Drop support for Python < 3.5. Python versions < 3.5 have reached end-of-life and as such, no security or bug fixes will be provided for those versions.

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.
Werner Lemberg 149b9055 2020-02-29T20:28:03 ChangeLog entry for last commit.

See https://github.com/freetype/docwriter/issues/36 for more information. * docs/markdown/stylesheets/extra.css: (.md-typeset code) -> (.md-typeset pre>code) (pre) -> (pre>code) (p, .md-typeset p, h4): Remove commented styles. (table.index): Remove unused styles.
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.
Werner Lemberg 141da028 2020-02-27T09:49:06 Make `FT_HAS_*' and `FT_IS_*' really return true (#57906). * include/freetype/freetype.h (FT_HAS_*, FT_IS_*): Implement it.

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.

Avi Halachmi (:avih) cc17f852 2019-09-15T04:30:18 [cmake] Don't fail if brotli is missing (#56894). The libs which cmake controls are commented out at include/freetype/config/ftoption.h and cmake un-comment each enabled library, but the brotli option was not commented out, therefore `FT_CONFIG_OPTION_USE_BROTLI' remained defined even if brotli was missing/disabled/etc. Comment it such that cmake can control it, which means leaving it undefined if brotli is missing. * include/freetype/config/ftoption.h: Fix typo.
Werner Lemberg 3de1b8d0 2019-09-05T14:10:01 [cmake] Add brotli support. * CMakeLists.txt (FT_WITH_BROTLI): New option. * builds/cmake/FindBrotliDec.cmake: New file.
Werner Lemberg bbb14361 2019-09-05T12:37:03 FindHarfBuzz.cmake: Change indentation to two spaces; shorten lines.
Werner Lemberg 87f52252 2019-09-05T12:14:03 Fix handling of `AF_CONFIG_OPTION_INDIC'. * devel/ftoption.h, include/freetype/config/ftoption.h: `AF_CONFIG_OPTION_INDIC' needs `AF_CONFIG_OPTION_CJK'.
Werner Lemberg 12351eee 2019-09-05T12:02:59 CMakeLists.txt: Fix generation of DLL related stuff (#56852). Extract `version_info' variable from `builds/unix/configure.raw' and use the data to correctly set `LIBRARY_VERSION' and `LIBRARY_SOVERSION'. Also use the data to set `ft_version' field in `freetype2.pc'. Also fix the needed minimum version of HarfBuzz in `freetype2.pc'.
Werner Lemberg 3fa35aa4 2019-09-03T21:10:20 * src/sfnt/sfwoff2.c (compute_ULong_sum): Fix undefined shift. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16933
Werner Lemberg 543a3b93 2019-09-01T23:03:09 * src/sfnt/sfwoff2.c (woff2_open_font): Add sanity check. Don't trust `totalSfntSize' unconditionally. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16893
Dominik Röttsches cbee985a 2019-08-27T15:08:15 [woff2] Don't use `FT_UInt64' (#56815). * src/sfnt/sfwoff2.c (woff2_open_font): Use `FT_UInt32' for `file_offset'. This fixes builds on platforms where `FT_LONG64' is not defined while still being sufficient to store a file offset.
Werner Lemberg 59415658 2019-08-27T14:07:14 [truetype] Prevent crash in `TT_Set_Named_Instance' (#56813). * src/truetype/ttgxvar.c (TT_Set_Named_Instance): Fix error handling.
Werner Lemberg ed7e8194 2019-08-27T14:07:05 CHANGES: Updated.
Werner Lemberg eef5c1dd 2019-08-27T10:43:32 [woff2] Fix compiler warnings. * src/sfnt/sfwoff2.c (read_num_hmetrics): Remove unused argument `table_len'. Update caller. (triplet_decode, compute_bbox, store_loca, reconstruct_glyf): Make `i' variable unsigned. (reconstruct_glyph): Remove condition which is always false. (reconstruct_html): Removed unused argument `transformed_size'. Update caller. * src/sfnt/woff2tags.c (woff2_known_tags): Remove condition which is always false.
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.
