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 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.

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.
Nikhil Ramakrishnan 4d9b3d1d 2019-07-16T02:45:03 [woff2] Reconstruct `loca', `hmtx', and swap out stream. Add necessary functions to reconstruct loca and hmtx tables (the two remaining tables that can have a transform). `woff2_open_font' is now capable of loading a woff2 font face. This code may still need more refining and better memory management. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total (final) size of sfnt stream. (WOFF2_InfoRec): Add header checksum value. * src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index' parameter to its pointer so its value can be modified by `woff2_open_font'. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into sfnt buffer at given position. (write_buf): Add parameter `extend_buf' which allows caller to specify whether buffer should be reallocated before copying data. (WRITE_SFNT_BUF): Updated. (pad4, store_loca, reconstruct_htmx): New functions. (reconstruct_glyf): Calculate loca values and store them. (reconstruct_font): Call `reconstruct_hmtx', write table record entries, and calculate table checksums. Also calculate font checksum and update `checksumAdjustment' entry in head table. (woff2_open_font): Open stream for sfnt buffer, swap out input stream and return. * src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept pointer to `face_index'.
Nikhil Ramakrishnan e3953e54 2019-07-13T03:14:17 [woff2] Reconstruct transformed `glyf' table. Reconstruct `glyf' table if it is transformed in the uncompressed table stream. Also add necessary structures, macros and functions. * include/freetype/internal/wofftypes.h (WOFF2_InfoRec, WOFF2_SubstreamRec, WOFF2_PointRec): New structures. (WOFF2_TableRec): s/OrigLength/dst_length/. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use `FT_SET_ERROR' to set implicit `error' variable. (WRITE_SHORT): New macro. (N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM, COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to refer to substreams of the transformed `glyf' tables. (Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX' macros. (with_sign, safe_int_addition): New functions to add sign to values based on a flag and perform safe addition respectively. (triplet_decode): Decode variable-length (flag, xCoordinate, yCoordinate) triplet for a simple glyph. See https://www.w3.org/TR/WOFF2/#triplet_decoding (store_points, compute_bbox, composteGlyph_size, reconstruct_glyf): New functions. (reconstruct_font): Call `reconstruct_glyf'. * src/sfnt/sfwoff2.h: Add required constants. * src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'.
Nikhil Ramakrishnan 81cf5326 2019-07-06T18:05:18 [woff2] Copy un-transformed tables to sfnt stream. Copy un-transformed tables to the sfnt stream. * src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro. (write_buf): New function. Extend memory of `dst' buffer and copy bytes from `src'. (compute_ULong_sum): New function. Calculate checksum of table. (reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte** sfnt_bytes'. This has been done because we reallocate memory to `sfnt' multiple times, which may change the pointer value of `sfnt'. This new pointer must be propogated back to the caller. Same reason for using a double pointer in `write_buf'. * src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for overflow checking.
Nikhil Ramakrishnan 106bacf5 2019-07-05T01:09:52 [woff2] Create stream for uncompressed buffer. Uncompressed buffer is now an `FT_Stream'. Perform basic checks and start iterating over tables. * src/sfnt/sfwoff2.c (stream_close, find_table, read_num_hmetrics): New functions. (reconstruct_font): Modify parameters and iterate over tables. (woff2_open_font): Updated.
Nikhil Ramakrishnan 18f6ff11 2019-07-01T01:29:30 [woff2] Handle TTCs and start reconstructing font. We `handle' TTCs by modifying the `indices' array to point to only those tables that are part of the requested `face_index'. Set and use `num_tables' in `WOFF2_TtcFont'. * src/sfnt/sfwoff2.c (reconstruct_font): New function. (woff2_open_font): Start reconstruction of font.
Nikhil Ramakrishnan 7a1639bc 2019-06-30T20:01:20 [woff2] Get known tags from function. Change `KnownTags' to a function (`woff2_known_tags'). This avoids introducing a global constant array. This function returns the specified index without *any* checks. The caller must ensure that `index' is within array limits. * src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]' notation to `woff2_known_tags( ... )'. * src/sfnt/woff2tags.c: Perform changes. * src/sfnt/woff2tags.h: Update definitions.
Nikhil Ramakrishnan c6c2c0b5 2019-06-30T19:32:27 [woff2] Minor. * src/sfnt/sfwoff2.c (woff2_uncompress): Add error message (woff2_open_font): Free `uncompressed_buf'.
Nikhil Ramakrishnan fc65d45a 2019-06-30T04:31:04 [woff2] Uncompress Brotli streams and `face_index' support. WOFF2 compressed stream is now uncompressed if Brotli is available. This data is stored in a separate buffer (uncompressed_buf) because it does not contain direct table data. Certain tables have transformations applied to them, and they must be reconstructed before we can write those tables to the SFNT stream. `face_index' is now being passed as a parameter to `woff2_open_font'. * src/sfnt/sfobjs.c (sfnt_open_font): Add parameter `face_instance_index'. * src/sfnt/sfwoff2.c (woff2_uncompress): New function. (woff2_open_font): Call `woff2_uncompress'. (compute_first_table_offset): Fix return type. * src/sfnt/sfwoff2.h (woff2_open_font): Modify declaration.
Nikhil Ramakrishnan 76c64f6b 2019-06-24T01:07:18 [woff2] Write SFNT Offset table. * src/sfnt/sfwoff2.c (WRITE_USHORT, WRITE_ULONG): New macros. (compare_tags): New function. (woff2_open_font): Implement it.
Nikhil Ramakrishnan e09fe4cc 2019-06-18T19:58:55 * src/sfnt/sfwoff2.c: #undef macros.
Nikhil Ramakrishnan e496cb29 2019-06-16T18:56:18 [woff2] Read table and collection directory. * include/freetype/internal/wofftypes.h (WOFF2_TtcFontRec): New structure. (WOFF2_HeaderRec): Add more fields. * src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128, ROUND4): New macros. (Read255UShort, CollectionHeaderSize, compute_first_table_offset): New functions. (ReadBase128): Use `FT_READ_BYTE'. (woff2_open_font): Add functionality to read table directory and collection directory (if present).
Nikhil Ramakrishnan 8c1e3fc3 2019-06-16T18:40:48 [sfnt] Include `woff2tags.c' for building. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `woff2tags.c'. * src/sfnt/sfnt.c: Include `woff2tags.c'.
Nikhil Ramakrishnan b45c7dd5 2019-06-16T17:55:59 [sfnt] Add WOFF2 constants. Add constants required for WOFF2, and known table tags as defined in the specification. See https://www.w3.org/TR/WOFF2/#table_dir_format for details. * src/sfnt/woff2tags.c, src/sfnt/woff2tags.h: New files.
Nikhil Ramakrishnan 2fa573c1 2019-06-12T00:21:20 [sfnt] Read WOFF 2 header. Check for WOFF2 tag, call `woff2_open_font', and implement it to read header according to specification. * include/freetype/internal/fttrace.h: Add `sfwoff2.c'. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `sfwoff2.c'. * src/sfnt/sfnt.c: Include `sfwoff2.c'. * src/sfnt/sfobjs.c (sfnt_open_font): Check for `wOF2' tag and call `woff2_open_font'. * src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h: New files.
Werner Lemberg 9adc3b35 2019-08-26T20:36:19 * src/psaux/cffdecode.c (cff_operator_seac): Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16470
Werner Lemberg 7d1d3b9a 2019-08-26T09:08:56 [type1] Fix `FT_Get_Var_Axis_Flags' (#56804). * src/type1/t1load.c (T1_Get_MM_Var): Allocate space for axis flags. Also remove redundant assignment.
Alexei Podtelezhnikov 12af46b6 2019-07-23T22:38:30 * src/base/ftbbox.c (cubic_peak): Sanitize left shift (#56586).
Weiyi Wu d5522ac0 2019-07-22T09:49:22 * src/cid/cidload.c (cid_hex_to_binary): Fix typo (#56653).
Werner Lemberg b110acba 2019-07-12T11:36:12 [sfnt, winfonts] Avoid memory leaks in case of error (#56587). * src/sfnt/sfwoff.c (woff_open_font): Call `FT_FRAME_EXIT' in case of error. * src/winfonts/winfnt.c (fnt_face_get_dll_font): Ditto.
