| 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. | ||
| 4d9b3d1d | 2019-07-16 02:45:03 | [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'. | ||
| e3953e54 | 2019-07-13 03:14:17 | [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'. | ||
| 81cf5326 | 2019-07-06 18:05:18 | [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. | ||
| 106bacf5 | 2019-07-05 01:09:52 | [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. | ||
| 18f6ff11 | 2019-07-01 01:29:30 | [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. | ||
| 7a1639bc | 2019-06-30 20:01:20 | [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. | ||
| c6c2c0b5 | 2019-06-30 19:32:27 | [woff2] Minor. * src/sfnt/sfwoff2.c (woff2_uncompress): Add error message (woff2_open_font): Free `uncompressed_buf'. | ||
| fc65d45a | 2019-06-30 04:31:04 | [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. | ||
| 732da8a4 | 2019-06-30 04:15:55 | * builds/unix/configure.raw: Change argument name to `brotli'. | ||
| 9443a1bc | 2019-06-28 01:01:17 | Add Brotli dependency and required checks. Brotli is required for decompressing WOFF2 font directory streams. The library is thus being added as an optional dependency for FreeType. * builds/unix/configure.raw: Add checks for `libbrotlidec'. (REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_BROTLI): New macro. | ||
| 76c64f6b | 2019-06-24 01:07:18 | [woff2] Write SFNT Offset table. * src/sfnt/sfwoff2.c (WRITE_USHORT, WRITE_ULONG): New macros. (compare_tags): New function. (woff2_open_font): Implement it. | ||
| e09fe4cc | 2019-06-18 19:58:55 | * src/sfnt/sfwoff2.c: #undef macros. | ||
| e496cb29 | 2019-06-16 18:56:18 | [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). | ||
| 8c1e3fc3 | 2019-06-16 18:40:48 | [sfnt] Include `woff2tags.c' for building. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `woff2tags.c'. * src/sfnt/sfnt.c: Include `woff2tags.c'. | ||
| b45c7dd5 | 2019-06-16 17:55:59 | [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. | ||
| 2fa573c1 | 2019-06-12 00:21:20 | [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. | ||
| 83dba0e9 | 2019-06-11 23:40:19 | Add structures for WOFF2. Add structures and macro for WOFF 2 header and table directory. * include/freetype/internal/wofftypes.h (WOFF2_HeaderRec, WOFF2_TableRec_): New structures. * include/freetype/tttags.h (TTAG_wOF2): New macro. | ||
| 9adc3b35 | 2019-08-26 20:36:19 | * src/psaux/cffdecode.c (cff_operator_seac): Fix numeric overflow. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=16470 | ||
| 7d1d3b9a | 2019-08-26 09:08:56 | [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. | ||
| 734d60f6 | 2019-08-06 20:38:17 | Another minor documentation improvement. | ||
| ad3443c9 | 2019-08-05 10:00:41 | Minor documentation improvement. | ||

| b110acba | 2019-07-12 11:36:12 | [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. | ||
| 12e4307d | 2019-07-12 10:48:10 | Properly handle phantom points for variation fonts (#56601). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Scale phantom points if HVAR and/or VVAR is present. | ||
| 05439f5c | 2019-07-04 14:28:04 | [psaux] (2/2) Handle fonts that use SEAC for ligatures (#56580). The same as previous commit but for the old engine. * src/psaux/t1decode.c (t1operator_seac): Implement it. | ||
| f2b64583 | 2019-07-04 14:04:52 | [psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580). As originally intended, a Type 1 SEAC charstring would be used for an accented glyph (like `acaron' or `uumlaut'), where the advance width of the SEAC glyph is the same as that of the `base' glyph (like `a' or `u'). In this case it is not uncommon for the SEAC glyph to not use an (H)SBW opcode of its own but to rely on the value from the base glyph. However, out-of-spec fonts also use SEAC glyphs for ligatures (like `oe' or `fi'), and in those cases the overall advance width is greater than that of the `base' glyph. For this reason we have to allow that the SEAC glyph can have an (H)SBW value of its own, and if it has, retain this value, rather than the one from the base glyph. * src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>: Implement it. | ||
| 8cf046c3 | 2019-07-01 13:54:54 | * Version 2.10.1 released. ========================== Tag sources with `VER-2-10-1'. * docs/VERSION.TXT: Add entry for version 2.10.1. * README, Jamfile (RefDoc), src/base/ftver.rc, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.10.0/2.10.1/, s/2100/2101/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 23:1:17. * CMakeLists.txt (VERSION_PATCH): Set to 1. * include/freetype/fterrors.h (FT_Error_String): Fix C++ compilation. | ||

| e7ac9288 | 2019-06-13 00:17:36 | [smooth] Restore the span buffering for direct mode only. The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be enough to cover the entire scanline for simple glyphs in most cases: each slightly slanted edge needs up to two spans, plus a filling span in-between. This is not new, we used to do it before cb4388783cecc. * src/smooth/ftgrays.c (gray_TWorker): Add `spans' and `num_spans'. (gray_hline, gray_sweep): Implement the span buffering. (gray_raster_render): Use negative `num_spans' to avoid the direct mode. | ||
| 59e0c6f9 | 2019-06-12 22:30:21 | * include/freetype/ftmodapi.h (FT_DebugHook_Func): Return error. Fix a warning by adding a return value as in `TT_RunIns', which should not be a compatibility issue. | ||

| 37580053 | 2019-05-16 12:15:54 | [truetype] Use 26.6 format for storing unscaled CVT values. If `CVAR' data is applied to variation fonts, fractional values are possible. * include/freetype/internal/tttypes.h (TT_FaceRec): Change type of `cvt' from `FT_Short' to `FT_Int32'. * src/truetype/ttgxvar.c (FT_fdot6ToFixed): New macro.

(TT_Process_Simple_Glyph): Use it. The `unrounded' array is active for variation fonts only, thus also enclose related code with `#ifdef TT_CONFIG_OPTION_GX_VAR_SUPPORT ... #endif' where necessary. Revert commit a113e5d from 2019-05-09, and don't use `extra_points2' but allocate a temporary array.

| 2ea511ee | 2019-04-29 22:49:15 | [smooth] Simplify cubic Bézier flattening. The previous implementation is correct but it is too complex. The revised algorithm is based on the fact that each split moves the control points closer to the trisection points on the chord. The corresponding distances are good surrogates for the curve deviation from the straight line. This cubic flattening algorithm is somewhat similar to the conic algorithm based the distance from the control point to the middle of the chord. The cubic distances, however, decrease less predictably but are easy enough to calculate on each step. * src/smooth/ftgrays.c (gray_render_cubic): Replace the split condition. | ||

| c149f739 | 2019-04-17 07:49:17 | [pcf] Fix handling of undefined glyph (#56067). This commit fixes the changes from 2018-07-21, which broke charmap iteration. We now add the default character as a new glyph with index 0, thus increasing the number of glyphs by one (as before). * src/pcf/pcfread.c (pcf_get_metrics): Adjust to new artificial glyph with index 0. Limit number of elements to 65534. (pcf_get_bitmaps): Ditto. Unify two loops into one; this avoids allocation of an intermediate array. (pcf_get_encodings): Don't flip indices but copy glyph metrics of default character to index 0. Also handle invalid default character. * docs/CHANGES: Updated. | ||

| 6986ddac | 2019-03-31 11:08:49 | [cff] Fix boundary checks. 642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically allocated memory when parsing CFF files with the "old" engine. Bounds checks have never been updated, however, leading to pointless comparisons of pointers in some cases. This commit presents a solution for bounds checks in the CFF module with an extended logic for the "old" engine while staying as concise as possible for the "new" one. * src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and the additional field `t2_strings' within `CFF_ParserRec'. * src/cff/cffparse.c (cff_parser_within_limits): Move all boundary checks into this new function and update the rest of `cffparse.c' to use it.
