Werner Lemberg 4f7f6f6e 2015-10-11T07:55:25 [sfnt] Improve extraction of number of named instances. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check number of instances against `fvar' table size.
Werner Lemberg 8de39a79 2015-10-10T13:34:11 [sfnt] Fix infinite loops with broken cmaps (#46167). * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next): Take care of border condidions (i.e., if the loops exit naturally).
Werner Lemberg 983b00ec 2015-10-08T18:44:45 [sfnt] Fix some signed overflows (#46149). * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use `FT_MulDiv'.
Werner Lemberg 90e437e3 2015-10-01T20:00:27 [sfnt] Make `tt_cmap4_char_map_linear' more robust (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Take care of border conditions (i.e., if the loop exits naturally).
Werner Lemberg 5f8f44d2 2015-10-01T14:16:03 [sfnt] Make `tt_cmap4_char_map_linear' faster (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Use inner loop to reject too large glyph indices.
Werner Lemberg 2ff83a5c 2015-09-30T14:44:29 [sfnt] Rewrite `tt_cmap4_char_map_linear' (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Add code to better skip invalid segments. If searching the next character, provide a more efficient logic to speed up the code.
Werner Lemberg 5339c75e 2015-09-24T13:39:44 [sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs.
Werner Lemberg c409eb18 2015-09-24T12:39:38 [base, sfnt] Better checks for invalid cmaps (1/2). * src/base/ftobjs.c (FT_Get_Char_Index): Don't return out-of-bounds glyph indices. (FT_Get_First_Char): Updated. * src/sfnt/ttcmap.c (tt_cmap6_char_next): Don't return character codes greater than 0xFFFF. (tt_cmap8_char_index): Avoid integer overflow in computation of glyph index. (tt_cmap8_char_next): Avoid integer overflows in computation of both next character code and glyph index. (tt_cmap10_char_index): Fix unsigned integer logic. (tt_cmap10_char_next): Avoid integer overflow in computation of next character code. (tt_cmap12_next): Avoid integer overflows in computation of both next character code and glyph index.

Werner Lemberg 730b6d74 2015-09-19T12:41:12 [sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.
Werner Lemberg 14d6b5d7 2015-08-13T15:22:17 [truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks. (sfnt_load_face): Updated. * src/truetype/ttobjs.c (tt_face_init) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting the style name. * src/base/ftobjs.c (open_face_from_buffer, open_face_PS_from_sfnt_stream): Updated. * src/bdf/bdfdrivr.c (BDF_Face_Init): Updated. * src/cff/cffload.c (cff_font_load): Updated. * src/cff/cffobjs.c (cff_face_init): Make function exit early for pure CFF fonts if `font_index < 0'.

(CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.

Since FreeType returns this structure only as a pointer through `FT_Get_Sfnt_Table', there shouldn't be any ABI problems. * src/sfnt/ttload.c (tt_face_load_os2): Implement it. * docs/CHANGES: Updated.
Darrell Bellert 01af71d4 2013-10-02T22:04:07 * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.
Werner Lemberg 85a7fdf3 2013-08-29T21:03:05 [sfnt] Fix frame access while reading WOFF table directory. * src/sfnt/sfobjs.c (woff_open_font): Using single memory frame while reading the directory entries for the whole loop.
Werner Lemberg d689d1cf 2013-08-29T17:53:40 Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.
Behdad Esfahbod c799dd67 2013-08-27T21:46:03 * src/sfnt/ttload.c (tt_face_load_font_dir): Fix sign typos.
Werner Lemberg 74a9b670 2013-08-02T14:53:32 [sfnt] Fix compilation with g++. * src/sfnt/pngshim.c (error_callback, read_data_from_FT_stream): Use cast. (Load_SBit_Png): Pacify compiler.
Werner Lemberg e8ed2d62 2013-08-01T12:20:20 Another round of cppcheck nitpicks. The call was (from the top-level of the FreeType tree): cppcheck --force \ --enable=all \ -I /usr/include \ -I /usr/local/include \ -I /usr/lib/gcc/i586-suse-linux/4.7/include \ -I include \ -I include/freetype \ -I include/freetype/config \ -I include/freetype/internal \ -DFT2_BUILD_LIBRARY \ . &> cppcheck.log using cppcheck git commit f7e93f99. Note that cppcheck still can't handle `#include FOO' (with `FOO' a macro). */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/gxvalid/*: Comment out redundant code or guard it with FT_DEBUG_LEVEL_TRACE.
Behdad Esfahbod 21c32b08 2013-07-25T21:53:18 Add FT_FACE_FLAG_COLOR and FT_HAS_COLOR. Also disambiguate Google's color bitmap tables. * include/freetype/freetype.h (FT_FACE_FLAG_COLOR, FT_HAS_COLOR): New macros. * include/freetype/internal/tttypes.h (TT_SbitTableType): Add TT_SBIT_TABLE_TYPE_CBLC. * src/sfnt/sfobjs.c (sfnt_load_face): Handle FT_FACE_FLAG_COLOR. * src/sfnt/ttsbit.c (tt_face_load_sbit, tt_face_load_strike_metrics, tt_face_load_sbit_image): Handle TT_SBIT_TABLE_TYPE_CBLC.
suzuki toshiya b4725cb7 2013-07-24T14:25:39 [sfnt] Fix for `make multi' target. * src/sfnt/pngshim.c (Load_SBit_Png): Use FT_LOCAL_DEF().
Behdad Esfahbod ff269528 2013-07-20T08:02:39 [sfnt] Fix `sbix' table version handling. * src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]: USHORT version numbers are to be considered as `minor'.
Behdad Esfahbod 778a7e6a 2013-07-19T14:28:28 [sfnt] `sbix' fix-ups. * src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps are rendered scaled and then the `glyf' outline rendered on top. We don't support that yet, so just ignore the `glyf' outline and advertise it as a bitmap-only font. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) [TT_SBIT_TABLE_TYPE_SBIX]: Return metrics in 26.6 units. (tt_face_load_sbix_image): Typo.
Werner Lemberg 01705395 2013-07-18T13:13:12 [sfnt] Add support for Apple's `sbix' color bitmap table. * include/freetype/internal/tttypes.h (TT_SBit_MetricsRec): Widen fields to FT_Short and FT_UShort, respectively. (TT_SBitTableType): New enumeration. (TT_FaceRec): Add `sbit_table_type' field. * include/freetype/tttags.h (TTAG_sbix): New macro. * src/sfnt/pngshim.c (Load_SBit_Png): Pass a more generic FT_GlyphSlot argument instead FT_Bitmap. Add flag to control map and metrics handling. Update all users. * src/sfnt/ttsbit.c: Include `ttmtx.h'. (tt_face_load_eblc): Renamed to... (tt_face_load_sbit): This. Handlic `sbix' bitmaps. (tt_face_free_eblc): Renamed to... (tt_face_load_sbit): This. Updated. (tt_face_load_strike_metrics): Handle `sbix' bitmaps. (tt_face_load_sbix_image): New function. (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_image, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_png, tt_sbit_decoder_load_image, tt_sbit_decoder_load_bitmap): Don't pass and handle load flags. (tt_sbit_decoder_load_bitmap) [!FT_CONFIG_OPTION_USE_PNG]: Better handle formats 17-19. Move color to grayscale conversion to... (tt_face_load_sbit_image): Here. Handle `sbix' bitmaps. * src/sfnt/pngshim.h: Updated. * src/sfnt/ttsbit.h: Updated. * src/sfnt/sfdriver.c: Updated.
Werner Lemberg 274207eb 2013-07-18T12:38:57 [sfnt] Ignore invalid magic number in `head' or `bhed'. Other font engines seem to ignore it also. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/sfnt/ttload.c (check_table_dir): Don't abort but warn only if we have an invalid magic number.
Werner Lemberg aa0ac323 2013-07-02T10:36:26 [sfnt] Fix documentation of `tt_face_get_metrics'. Problem reported in Savannah bug #39383.
Werner Lemberg a25ecfdd 2013-06-10T12:57:16 [sfnt] Improve embedded bitmap tracing. * src/base/ftobjs.c (FT_Request_Size): Move trace message regarding bitmap strike match to... (FT_Match_Size): This function. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_png, tt_sbit_decoder_load_image): Decorate with tracing messages.
Werner Lemberg 45392b77 2013-06-05T13:43:20 Fix compiler warnings. * include/freetype/internal/ftmemory.h: Decorate memory allocation macros with `FT_Long' where appropriate. Remove duplicate of FT_MEM_QRENEW_ARRAY definition. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Use cast. * src/base/ftobjs.c: Add warning disabling pragma for MSVC while including `md5.c'. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdESC>: Add cast. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_compound): Fix casts. (tt_sbit_decoder_load_bitmap): Beautification. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Initialize variables (earlier). * src/truetype/ttgload.c (TT_Process_Simple_Glyph): Pacify compiler. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Use unsigned constants where appropriate. * src/type1/t1load.c (T1_Get_MM_Var): Ditto.
Behdad Esfahbod 760d342d 2013-05-29T11:36:18 Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated. (ft_gray_for_premultiplied_srgb_bgra): New function. (FT_Bitmap_Convert): Handle FT_PIXEL_MODE_BGRA. * src/sfnt/pngshim.c, src/sfnt/pngshim.h: New files. * src/sfnt/sfnt.c: Include `pngshim.c'. * src/sfnt/ttsbit.c: Include FT_BITMAP_H and `pngshim.h' (tt_face_load_eblc): Load `CBLC'. (tt_sbit_decoder_init): Load `CBDT'. (tt_sbit_decoder_alloc_bitmap): Pass load flags to select between color and grayscale bitmaps. Set `num_grays'. This is used by `ftview' to choose the blending algorithm. (tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_image): Pass load flag. s/write/pwrite/. Don't call `tt_sbit_decoder_alloc_bitmap'. Updated. (tt_sbit_decoder_load_png) [FT_CONFIG_OPTION_USE_PNG]: New function. (tt_sbit_decoder_load_bitmap): Pass load flag. Handle new glyph formats 17, 18, and 19. Call `tt_sbit_decoder_alloc_bitmap'. Flatten color bitmaps if necessary. (tt_face_load_sbit_image): Updated. * src/sfnt/rules.mk (SFNT_DRV_SRC): Add `pngshim.c'. * docs/CHANGES: Updated.
Werner Lemberg ea2b4756 2013-05-10T08:04:33 [sfnt] Clean up bitmap code. * src/sfnt/ttsbit.c: Deleted. * src/sfnt/ttsbit0.c: Renamed to `ttsbit.c'. * rules.mk (SFNT_DRV_H): Updated.
Werner Lemberg f6aa089f 2013-05-10T07:58:47 */* [FT_CONFIG_OPTION_OLD_INTERNALS]: Remove macro and guarded code.
Werner Lemberg 5ea06ce0 2013-03-17T08:14:46 Whitespace.
Werner Lemberg 89f50647 2013-03-14T17:50:49 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Werner Lemberg dbc6e3f1 2013-03-12T11:42:20 Remove `FT_KEEP_ERR_PREFIX'. The idea is to always have FT_ERR_PREFIX available internally. * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard undefinition of FT_ERR_PREFIX * src/gxvalid/gxverror.h, src/otvalid/otverror.h, src/sfnt/sferrors.h: Updated.
Xi Wang ba931be2 2013-01-25T00:57:09 [sfnt] Fix broken pointer overflow checks. Many compilers such as gcc and clang optimize away pointer overflow checks `p + n < p', because pointer overflow is undefined behavior. Use a safe form `n > p_limit - p' instead. Also avoid possible integer overflow issues, for example, using `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2' given a large `num_glyphs'. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Implement it.

Werner Lemberg cd3f871e 2013-01-16T19:56:08 [sfnt] Fix optimized sbit loader. It was not taking bit_depth into consideration when blitting! * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_byte_aligned, * tt_sbit_decoder_load_bit_aligned): Handle bit depth.
Werner Lemberg 309b8b31 2012-12-16T19:08:36 [sfnt] Fix Savannah bug #37936. * src/sfnt/ttload.c (tt_face_load_gasp): Avoid memory leak.
Andreas Pehnack 1e168834 2012-10-20T11:42:22 [sfnt] Load pure CFF fonts wrapped in SFNT container. Such fonts only have a `cmap' and a `CFF' table. * src/sfnt/ttload.c (tt_face_load_font_dir): Don't call `check_table_dir' if font signature is `OTTO'.
