Werner Lemberg 6689a009 2014-11-25T08:53:09 [Savannah bug #43682] Properly handle missing return errors. The functions in this patch *do* return non-trivial errors that must be taken care of. * src/autofit/afloader.c (af_loader_load_g), src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render), src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_endchar>, src/psaux/psobjs.c (ps_parser_load_field_table), src/psaux/t1decode (t1_decoder_parse_charstrings) <op_endchar>, src/truetype/ttgload.c (load_truetype_glyph <subglyph loop>, tt_loader_init, TT_Load_Glyph), src/truetype/ttgxvar.c (TT_Set_MM_Blend), src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Do it.
Werner Lemberg b24e8ba2 2014-11-25T08:30:49 [Savannah bug #43682] Add/remove `void' casts to some functions. We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it.
Werner Lemberg 6889f7b7 2014-11-24T17:16:08 Remove all code related to FT_MAX_CHARMAP_CACHEABLE. This is no longer used. * src/base/ftobjs.c, src/cache/ftccmap.c, src/cff/cffobjs.c, src/sfnt/ttcmap.c: Do it.
Werner Lemberg 23c093fc 2014-11-21T08:41:39 Minor.

Alexei Podtelezhnikov 2e73a1b4 2014-11-09T23:22:43 [base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justifed by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept.

Alexei Podtelezhnikov 7abdb8cc 2014-10-02T23:13:33 [base] Significant optimization of `ft_div64by32' We shift as many bits as we can into the high register, perform 32-bit division with modulo there, then work through the remaining bits with long division. This optimization is especially noticeable for smaller dividends that barely use the high register. * src/base/ftcalc.c (ft_div64by32): Updated.
Werner Lemberg c0ce72a6 2014-10-02T06:44:43 Formatting.

suzuki toshiya e2d2b154 2013-12-27T16:44:24 [ftrfork] Fix the face order difference between POSIX and Carbon. The fragmented resources in Suitcase and .dfont should be reordered when post resource for Type1 is being restored, but reordering of sfnt resources induces the different face order. Now the ordering is restricted to post resource only, to prevent the different order issue (e.g. the face index in the fontconfig cache generated with Carbon framework is incompatible with that by FreeType2 without Carbon framework.) Found by Khaled Hosny and Hin-Tak Leung. http://lists.gnu.org/archive/html/freetype-devel/2013-02/msg00035.html http://lists.gnu.org/archive/html/freetype-devel/2013-12/msg00027.html * src/base/ftrfork.c (FT_Raccess_Get_DataOffsets): Add a switch `sort_by_res_id' to control the fragmented resource ordering. * include/internal/ftrfork.h: Daclare new switch. * src/base/ftobjs.c (IsMacResource): Enable the soring for post resource, and disable the sorting for sfnt resource.
Werner Lemberg bd413862 2013-12-21T08:14:25 Fix PIC linking. * include/internal/ftrfork.h (CONST_FT_RFORK_RULE_ARRAY_BEGIN): Fix generated function name. * src/base/basepic.c (FT_Init_Table_raccess_guess_table): Rename to ... (FT_Init_Table_ft_raccess_guess_table): ... this so that the function name correctly corresponds to what the macro framework expects. * src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so that PIC functions are compiled also.
Werner Lemberg c4e968ed 2013-12-21T07:23:08 [base] Add missing dependencies to Makefile. * src/base/rules.mk (BASE_SRC): Add `basepic.c' and `ftpic.c'. (BASE_H): Add `basepic.h'.

Werner Lemberg 28626869 2013-11-20T21:06:18 [truetype] Don't trust `maxp's `maxSizeOfInstructions'. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html for details. * src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep' tables also for setting `autohint'. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from `TT_Process_Composite_Glyph' for handling unreliable values of `maxSizeOfInstructions'.
Werner Lemberg fae38207 2013-11-13T08:55:46 Simplify header file hierarchy. This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/*: Move up to... * include/*: ... this directory. * builds/amiga/include/freetype/*: Move up to... * builds/amiga/include/*: ... this directory. */*: Essentially do `s@/freetype/@/@' where appropriate. * CMakeList.txt: Simplify. * builds/unix/freetype-config.in, builds/unix/freetype2.in: For `--cflags', return a single directory. * builds/unix/install.mk (install): No longer try to remove `cache' and `internal' subdirectories; instead, remove the `freetype' subdirectory.
Werner Lemberg 604838d5 2013-10-22T01:10:10 * src/base/md5.c, src/base/md5.h: Updated to recent version. * src/base/ftobjs.c: Updated; `md5.c' no longer uses `free'.
Behdad Esfahbod 31e726d9 2013-09-20T07:20:53 Fix vertical size of emboldened glyphs. Cf. https://bugzilla.gnome.org/show_bug.cgi?id=686709 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Adjust `horiBearingY' also.
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'.

(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 bd3849e7 2013-08-27T21:43:38 FT_Open_Face: Improve external stream handling. If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to... (open_face): This function.
Werner Lemberg bcd8c0b0 2013-08-27T21:36:03 Remove `FT_SqrtFixed' function. It's no longer used. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c: Do it.

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.
Werner Lemberg cc34efca 2013-07-31T22:55:50 Minor.
suzuki toshiya f2e7f1e1 2013-07-30T13:32:57 2013-07-30 Behdad Esfahbod <behdad@google.com> Prevent division by zero by a transparent color. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Return 0 immediately, when alpha channel is zero.
Werner Lemberg 25b7da53 2013-06-19T10:23:36 * Version 2.5.0 released. ========================= Tag sources with `VER-2-5-0'. * docs/VERSION.DLL: Update documentation and bump version number to 2.5.0. * README, Jamfile (RefDoc), builds/win32/vc2005/freetype.vcproj, builds/win32/vc2005/index.html, builds/win32/vc2008/freetype.vcproj, builds/win32/vc2008/index.html, builds/win32/vc2010/freetype.vcxproj, builds/win32/vc2010/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualc/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj, builds/win32/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/2.4.12/2.5.0/, s/2412/250/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 5. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 16:2:10. * src/base/ftobjs.c (FT_Open_Face): Pacify compiler. * src/truetype/ttinterp.c (Ins_MSIRP, Ins_MIRP): Ditto.
Werner Lemberg f56691a8 2013-06-18T10:17:48 Fix Savannah bug #39269. * src/base/ftgloadr.c (FT_GlyphLoader_CheckPoints): Free memory in case of reacollocation failures.
Andrew Church 67cf7a88 2013-06-18T09:35:34 Fix Savannah bug #39266. If memory allocations fail at certain points while opening a font, FreeType can either crash due to a NULL dereference or leak memory. * include/freetype/internal/ftobjs.c (FT_Face_InternalRec, FT_LibraryRec): Make `refcount' a signed integer. If, for example, FT_Open_Face() fails in a memory allocation before the face's reference count is set to 1, a subsequent `FT_Done_Library' call would otherwise loop over `FT_Done_Face' 2^32 times before freeing the face. * src/base/ftobjs.c (open_face): Initialize `stream' and friends earlier. (FT_Open_Face) <Fail>: Behave correctly if `node' is NULL. (FT_Destroy_Module) <Fail>: Check that `renderer_clazz' is valid.
Werner Lemberg c06889eb 2013-06-12T10:58:06 More compiler warning fixes. */*: Use cast to `FT_Bool' (or `Bool') where appropriate.

Werner Lemberg 8d8508e4 2013-06-04T13:09:01 Missed some cppcheck items.
Werner Lemberg dc624ca4 2013-06-04T10:30:48 Apply fixes for cppcheck nitpicks. http://cppcheck.sourceforge.net/ Note that the current version heavily chokes on FreeType, delivering even wrong results. I will report those issues to the cppcheck team so that a newer version gives improved results hopefully. */* Improve variable scopes. */* Remove redundant initializations which get overwritten. * src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable): Remove unused variable. * src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero. * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt1_entry_validate): Remove functionless code. * src/tools/ftrandom.c (main): Fix memory leak.
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.
Brian Nixon 8d6025c8 2013-05-13T09:06:42 Fix Savannah bug #38970. * src/base/ftdebug.c, builds/win32/ftdebug.c, builds/wince/ftdebug.c, builds/amiga/src/base/ftdebug.c (ft_debug_init): Don't read past the environment variable FT2_DEBUG.
