11beee85 | 2020-04-08 09:05:32 | 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'. | |
 |
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. | |
|
13c0df80 | 2020-03-22 23:29:51 | [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'. | |
|
1fd31487 | 2020-03-21 20:17:17 | [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. See https://devguide.python.org/#status-of-python-branches for more information. * Jamfile (RefDoc): Add `site' parameter. * builds/detect.mk (std_setup): Update Python version requirement. * builds/freetype.mk (refdoc-venv): Use pip as `python -m pip'. * builds/unix/ax_compare_version.m4, builds/unix/ax_prog_python_version.m4: Macros to detect Python version. New files. * builds/unix/configure.raw: Check for Python >= 3.5 and remove check for `pip'. * docs/CHANGES, docs/INSTALL.GNU, docs/README: Updated. | |

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 However, this code breaks with the outdated internal version of zlib.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. | |

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. | |
|
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. | |
|
141da028 | 2020-02-27 09:49:06 | Make `FT_HAS_*' and `FT_IS_*' really return true (#57906). * include/freetype/freetype.h (FT_HAS_*, FT_IS_*): Implement it. | |

|
50b01387 | 2020-01-04 18:42:27 | Add reference to another oss-fuzz bug report. | |
|

Creating the API Reference in the (new) `reference' sub-directory is consistent with other documentation sub-topics, such as `design', `glyphs' and `tutorial'.

cc17f852 | 2019-09-15 04:30:18 | [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. | |
|
3de1b8d0 | 2019-09-05 14:10:01 | [cmake] Add brotli support. * CMakeLists.txt (FT_WITH_BROTLI): New option. * builds/cmake/FindBrotliDec.cmake: New file. | |

|
12351eee | 2019-09-05 12:02:59 | 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'. | |

|
cbee985a | 2019-08-27 15:08:15 | [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. | |

60c52f0e | 2019-08-27 10:08:01 | [woff2] Formatting; some comments. | |
|
86803acd | 2019-08-22 16:46:03 | [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. | |
|
d2681a49 | 2019-08-21 20:21:02 | [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 | |
|
1a103015 | 2019-08-17 14:57:59 | * src/sfnt/sfwoff2.c: Improve trace comments. Adjust tracing levels for comments, and more formatting. | |
|
97616704 | 2019-08-14 17:39:55 | [woff2] Formatting. * src/sfnt/sfobjs.c, src/sfnt/sfwoff2.c: Better formatting. | |
|
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. | |
|
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. |
