Since we consider `sbw' for the horizontal direction only, we still have to synthesize vertical metrics if the user wants to use the vertical writing direction. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is set. 2010-02-10 Ken Sharp <ken.sharp@artifex.com> Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of *one* direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it. 2010-02-08 Werner Lemberg <wl@gnu.org> * devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define. 2010-02-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Prevent NULL pointer dereference passed to FT_Module_Requester. * src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'. * src/psnames/psmodule.c (psnames_get_interface): Ditto. * src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'. * src/truetype/ttdriver.c (tt_get_interface): Ditto. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix memory leaks in previous patch. * src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings allocated for face->root.family_name and style_name. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> New parameters for FT_Open_Face() to ignore preferred family names. Preferred family names should be used for legacy systems that can hold only a few faces (<= 4) for a family name. Suggested by Andreas Heinrich. https://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html * include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY, FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define. * src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and ignore preferred family and subfamily names if requested. 2010-01-27 Ken Sharp <ken.sharp@artifex.com> Fix Savannah bug #28678. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_load_glyph): Handle vertical metrics correctly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle vertical metrics correctly. (T1_Load_Glyph): Don't synthesize vertical metrics. 2010-01-14 Werner Lemberg <wl@gnu.org> Make FT_Set_Transform work if no renderer is available. * src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation if no renderer is compiled into the library. 2010-01-14 Werner Lemberg <wl@gnu.org> Fix compilation warning. * src/base/ftbase.h: s/LOCAL_DEF/LOCAL/. * src/base/ftobjs.c: Include ftbase.h conditionally. 2010-01-11 Kwang Yul Seo <skyul@company100.net> Provide inline assembly code for RVCT compiler. This is Savannah patch #7059. * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER, FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define. 2010-01-08 Ken Sharp <ken.sharp@artifex.com> Fix Savannah bug #28521. Issue #28226 involved a work-around for a font which used the `setcurrentpoint' operator in an invalid way; this operator is only supposed to be used with the result of OtherSubrs, and the font used it directly. The supplied patch removed the block of code which checked this usage entirely. This turns out to be a Bad Thing. If `setcurrentpoint' is being used correctly it should reset the flex flag in the decoder. If we don't do this then the flag never gets reset and we omit any further contours from the glyph (at least until we close the path or similar). * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Handle `flex_state' correctly. 2010-01-05 Werner Lemberg <wl@gnu.org> Apply reports from clang static analyzer. * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c (FT_Stroker_ParseOutline), src/base/ftsynth.c (FT_GlyphSlot_Embolden): Remove dead code. * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize `offset_i' and `length_i'. 2010-01-05 Ralph Giles <giles@ghostscript.com> Enable the incremental font interface by default. Ghostscript requires the incremental font interface for handling some Postscript documents. It is moving to using FreeType as its primary renderer; supporting this in the default build makes it Ghostscript to be linked against the system FreeType when one is available. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL): Uncomment. 2010-01-05 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28395. * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c (T1_Load_Glyph): Don't check `num_glyphs' if incremental interface is used. 2010-01-05 Ken Sharp <ken.sharp@artifex.com> Make Type 1 `seac' operator work with incremental interface. This fixes Savannah bug #28480. * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names' if incremental interface is used. 2010-01-04 Ken Sharp <ken.sharp@artifex.com> Make incremental interface work with TrueType fonts. This fixes Savannah bug #28478. * src/truetype/ttgload.c (load_truetype_glyph): Don't check `glyf_offset' if incremental interface is used. 2009-12-31 Lars Abrahamsson <wonko@opera.com> Make compilation with FT_CONFIG_OPTION_PIC work again. * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]: Declare `library' for FT_BITMAP_GLYPH_CLASS_GET. * src/base/ftinit.c (ft_destroy_default_module_classes, ft_create_default_module_classes): Use proper casts (needed for C++ compilation). * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP. 2009-12-22 Marc Kleine-Budde <mkl@pengutronix.de> Make freetype-config aware of $SYSROOT. This is Savannah patch #7040. * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where appropriate. 2009-12-20 Werner Lemberg <wl@gnu.org> Fix compiler warning. Reported by Sean. * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty source files; however, some compilers warn about an unused variable declaration. This is now replaced with a typedef. 2009-12-18 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28320. There exist corrupt, subsetted fonts (embedded in PDF files) which contain a private dict that ends with an unterminated floating point number (no operator following). We now ignore this error (as acrobat does). * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for unterminated floating point numbers. 2009-12-16 Werner Lemberg <wl@gnu.org> Really fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS, GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros. 2009-12-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improve configure.raw to copy some options from CFLAGS to LDFLAGS. The linker of Mac OS X 10.6 is sensitive to the architecture. If the architectures are specified explicitly for the C compiler, the linker requires the architecture specifications too. * builds/unix/configure.raw: Replace `-isysroot' option parser by more generic argument parser. 2009-12-15 Werner Lemberg <wl@gnu.org> Fix compiler warnings. Reported by Sean. * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data type. 2009-12-14 Ken Sharp <ken.sharp@artifex.com> Ignore invalid `setcurrentpoint' operations in Type 1 fonts. This fixes Savannah bug #28226. At least two wild PostScript files of unknown provenance contain Type 1 fonts, apparently converted from TrueType fonts in earlier PDF versions of the files, which use the `setcurrentpoint' operator inappropriately. FreeType currently throws an error in this case, but Ghostscript and Adobe Distiller both accept the fonts and ignore the problem. This commit #ifdefs out the check so PostScript interpreters using FreeType can render these files. The specification says `setcurrentpoint' should only be used to set the point after a `Subr' call, but these fonts use it to set the initial point to (0,0). Unnecessarily so, as they correctly use an `hsbw' operation which implicitly sets the initial point. * src/psaux/t1decode.c (t1_decoder_parse_charstrings) <op_setcurrentpoint>: Comment out code. 2009-12-14 Bram Tassyns <bramt@enfocus.be> Fix parsing of /CIDFontVersion. This fixes Savannah bug #28287. * src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in t1tables.h) is of type FT_Fixed. 2009-12-14 Werner Lemberg <wl@gnu.org> Trace glyph index in CID module. Suggested in Savannah patch #7023. * src/cid/cidgload.c (cid_load_glyph): Add tracing message. 2009-12-03 Werner Lemberg <wl@gnu.org> Fix compiler warnings. * src/truetype/ttgload.c (tt_get_metrics): Put `Exit' label into the proper preprocessor conditional. * src/pfr/pfrobjs.c (pfr_slot_load): Pacify gcc. 2009-11-25 John Tytgat <John.Tytgat@esko.com> Better handling of start of `eexec' section. This fixes Savannah bug #28090. * src/type1/t1parse.c (T1_Get_Private_Dict): Skip all whitespace characters before start of `eexec' section. 2009-11-20 Werner Lemberg <wl@gnu.org> Fix Savannah bug #27742. * src/base/ftstroke.c (ft_stroker_outside): Avoid silent division by zero, using a threshold for `theta'. 2009-11-20 Werner Lemberg <wl@gnu.org> Fix Savannah bug #28036. * src/type1/t1afm.c (t1_get_index): Fix comparison. 2009-11-16 Werner Lemberg <wl@gnu.org> Fix compiler warnings.

The hash API in BDF driver is designed to be generic, it takes void * typed data. But BDF driver always gives an unsigned long integer (the index to a property).

The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec.

This fixes Savannah bug #26867. Previously, only integers have been used which can lead to serious rounding errors. However, fractional values are only used internally; after the charstrings (of either Type 1 or 2) have been processed, the resulting coordinates get rounded to integers currently -- before applying scaling. This should be fixed; at the same time a new load flag should be introduced, to be used in combination with FT_LOAD_NO_SCALE, which indicates that font units are returned in 16.16 format. Similarly, the incremental interface should be extended to allow fractional values for metrics. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift' field. * include/freetype/internal/pshints.h (T1_Hints_SetStemFunc, T1_Hints_SetStem3Func): Use FT_Fixed for coordinates. * src/psaux/psobjs.c: Include FT_INTERNAL_CALC_H.

Normally, the SCANMODE instruction (if present) to set the drop-out mode in a TrueType font is located in the `prep' table only and thus valid for all glyphs. However, there are fonts like `pala.ttf' which additionally contain this instruction in the hinting code of some glyphs (but not all). As a result it can happen that a composite glyph needs multiple drop-out modes for its subglyphs since the rendering state gets reset for each subglyph. FreeType collects the hinted outlines from all subglyphs, then it sends the data to the rasterizer. It also sends the drop-out mode -- after hinting has been applied -- and here is the error: It sends the drop-out mode of the last subglyph only; drop-out modes of all other subglyphs are lost. This patch fixes the problem; it adds a second, alternative mechanism to pass the drop-out mode: For each contour, the rasterizer now checks the first `tags' array element. If bit 2 is set, bits 5-7 contain the contour's drop-out mode, overriding the global drop-out mode. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in `tags[0]'. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom): Use bits 3-5 instead of 0-2.

(Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out mode. 2009-06-16 Werner Lemberg <wl@gnu.org> Improve scan conversion rules 4 and 6. Two new constraints are introduced to better identify a `stub' -- a concept which is only vaguely described in the OpenType specification. The old code was too rigorous and suppressed more pixel than it should. . The intersection of the two profiles with the scanline is less than a half pixel. Code related to this was already present in the sources but has been commented out. . The endpoint of the original contour forming a profile has a distance (`overshoot') less than half a pixel to the scanline. Note that the two additional conditions fix almost all differences to the Windows rasterizer, but some problematic cases remain. * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New macros for the `flags' field in the `TProfile' structure. (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros. (New_Profile, End_Profile): Pass overshoot flag as an argument and set it accordingly. Update callers.

This patch fixes the following problems in ttsbit0.c: . Bitmaps for compound glyphs were never allocated. . `SBitDecoder' refused to load metrics if some other metrics have already been loaded. This condition certainly makes no sense for recursive calls, so I've just disabled it. Another possibility would be resetting `decoder->metrics_loaded' to false before loading each composite component. However, we must restore the original metrics after finishing the recursion; otherwise we can get a misaligned glyph. . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos', causing some glyph components to be shifted too far to the right (especially noticeable for small sizes). Note that support for grayscale bitmaps (not necessarily compound) is completely broken in ttsbit0.c. * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics. (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case of `h == height'. (tt_sbit_decoder_load_compound): Reset metrics after loading components.

Fix return value for non-PFR fonts. Both problems reported by Chi Nguyen <chint@necsv.com>. 2008-12-21 anonymous FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE. 2008-12-21 Hongbo Ni <hongbo@njstar.com> * src/autofit/aflatin.c (af_latin_hint_edges), src/autofit/aflatin2.c (af_latin2_hint_edges), src/autofit/afcjk.c (af_cjk_hint_edges): Protect against division by zero. This fixes Savannah bug #25124. 2008-12-18 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-12-18 David Bevan <dbevan@emtex.com> Provide API for accessing embedding and subsetting restriction information. * include/freetype.h (FT_FSTYPE_INSTALLABLE_EMBEDDING, FT_FSTYPE_RESTRICTED_LICENSE_EMBEDDING, FT_FSTYPE_PREVIEW_AND_PRINT_EMBEDDING, FT_FSTYPE_EDITABLE_EMBEDDING, FT_FSTYPE_NO_SUBSETTING, FT_FSTYPE_BITMAP_EMBEDDING_ONLY): New macros. (FT_Get_FSType_Flags): New function declaration. * src/base/ftobjs.c (FT_Get_FSType_Flags): New function. * src/cid/cidtoken.h, src/type1/t1tokens.h, src/type42/t42parse.c (t42_keywords): Handle `FSType'. * include/freetype/t1tables.h (PS_FontInfoRec): Add `fs_type' field. 2008-12-17 Werner Lemberg <wl@gnu.org> * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Don't use internal macros so that copying the source code into an application works out of the box. 2008-12-17 Werner Lemberg <wl@gnu.org> * include/freetype/ftsynth.h, src/base/ftsynth.c: Move FT_GlyphSlot_Own_Bitmap to... * include/freetype/ftbitmap.h, src/base/ftbitmap.c: These files. * docs/CHANGES: Document it. 2008-12-10 Werner Lemberg <wl@gnu.org> Generalize the concept of `tricky' fonts by introducing FT_FACE_FLAG_TRICKY to indicate that the font format's hinting engine is necessary for correct rendering. At the same time, slightly modify the behaviour of tricky fonts: FT_LOAD_NO_HINTING is now ignored. To really force raw loading of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and FT_LOAD_NO_AUTOHINT must be used. Finally, tricky TrueType fonts always use the bytecode interpreter even if the patented code is used. * include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY): New macros. * src/truetype/ttdriver.c (Load_Glyph): Handle new load flags semantics as described above. * src/truetype/ttobjs.c (tt_check_trickyness): New function, using code of ... (tt_face_init): This function, now simplified and updated to new semantics. * src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky fonts. * docs/CHANGES: Document it. 2008-12-09 Werner Lemberg <wl@gnu.org> Really fix Savannah bug #25010: An SFNT font with neither outlines nor bitmaps can be considered as containing space `glyphs' only. * src/truetype/ttpload.c (tt_face_load_loca): Handle the case where a `glyf' table is missing. * src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no `glyf' table but a non-zero `loca' entry. (tt_loader_init): Handle missing `glyf' table. * src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05. * src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines nor bitmaps is scalable. 2008-12-05 Werner Lemberg <wl@gnu.org> * src/autofit/aflatin.c (af_latin_uniranges): Add more ranges. This fixes Savannah bug #21190 which also provides a basic patch. 2008-12-05 Werner Lemberg <wl@gnu.org> * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value 0x100 instead of 0x10000; the latter value is already occupied by FT_LOAD_TARGET_LIGHT. Bug reported by James Cloos. Handle SFNT with neither outlines nor bitmaps. This fixes Savannah bug #25010. * src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither outlines nor bitmaps. * src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there is no table with glyphs. * src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging message. 2008-12-01 Werner Lemberg <wl@gnu.org> GDEF tables need `glyph_count' too for validation. Problem reported by Chi Nguyen <chint@necsv.com>. * src/otvalid/otvgdef.c (otv_GDEF_validate), src/otvalid/otvalid.h (otv_GDEF_validate), src/otvalid/otvmod.c (otv_validate): Pass `glyph_count'. 2008-11-29 Werner Lemberg <wl@gnu.org> * src/autofit/afcjk.c, src/base/ftoutln.c, src/base/ftrfork.c, src/bdf/bdfdrivr.c, src/gxvalid/gxvmorx.c, src/otvalid/otvmath.c, src/pcf/pcfdrivr.c, src/psnames/pstables.h, src/smooth/ftgrays.c, src/tools/glnames.py, src/truetype/ttinterp.c, src/type1/t1load.c, src/type42/t42objs.c, src/winfonts/winfnt.c: Fix compiler warnings (Atari PureC). 2008-11-29 James Cloos <cloos@jhcloos.com> * src/type/t1load.c (mm_axis_unmap): Revert previous patch and fix it correctly by using FT_INT_TO_FIXED (FreeType expects 16.16 values in the /BlendDesignMap space). 2008-11-29 James Cloos <cloos@jhcloos.com> * src/type1/t1load.c (mm_axis_unmap): `blend_points' is FT_Fixed*, whereas `design_points' is FT_Long*. Therefore, return blend rather than design points. 2008-11-27 Werner Lemberg <wl@gnu.org> * src/cff/cffparse.c (cff_parse_real): Handle more than nine significant digits correctly. This fixes Savannah bug #24953. 2008-11-25 Daniel Zimmermann <netzimme@aol.com> * src/base/ftstream.c (FT_Stream_ReadFields): Don't access stream before the NULL check. From Savannah patch #6681. 2008-11-24 Werner Lemberg <wl@gnu.org> Fixes from the gnuwin32 port. * src/base/ftlcdfil.c: s/EXPORT/EXPORT_DEF/. * src/base/ftotval.c: Include FT_OPENTYPE_VALIDATE_H. * src/psaux/psobjs.c (ps_table_add): Check `length'. 2008-11-15 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (tt_default_graphics_state): The default value for `scan_type' is zero, as confirmed by Greg Hitchcock from Microsoft.

Reported by Graham Asher. 2008-11-08 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (tt_face_get_name): Modified to return an error code so that memory allocation problems can be distinguished from missing table entries. Reported by Graham Asher. (GET_NAME): New macro. (sfnt_load_face): Use it. 2008-11-05 Werner Lemberg <wl@gnu.org> * devel/ftoption.h, include/freetype/config/ftoption.h [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Undefine TT_CONFIG_OPTION_UNPATENTED_HINTING. This fixes the return value of `FT_Get_TrueType_Engine_Type' (and makes it work as documented).

Other errors are returned by SFNT_Err_Unknown_File_Format. * src/base/ftobjs.c (FT_Open_Face): When TrueType driver returns `FT_Err_Table_Missing', try `open_face_PS_from_sfnt_stream'. It is enabled only when old mac font support is configured. 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * include/freetype/tttags.h (TTAG_CID, TTAG_FOND, TTAG_LWFN, TTAG_POST, TTAG_sfnt, TTAG_TYP1, TTAG_typ1): New tags to simplify the repeated calculations of these values in ftobjs.c and ftmac.c. * src/base/ftobjs.c: Replace all FT_MAKE_TAG by new tags. * src/base/ftmac.c: Ditto. * builds/mac/ftmac.c: Ditto. 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (ft_lookup_PS_in_sfnt_stream): Remove wrong initialization of *is_sfnt_cid. 2008-10-04 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Remove compiler warnings. 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Replaced by...

It checks whether the stream is sfnt-wrapped Type1 PS font or sfnt-wrapped CID-keyed font, then try to open a face for given face_index. (Mac_Read_sfnt_Resource): Replace the combination of `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' by `open_face_PS_from_sfnt_stream'. * src/base/ftmac.c (FT_New_Face_From_SFNT): Ditto. * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto. * src/base/ftbase.h: Remove `ft_lookup_PS_in_sfnt' and add `open_face_PS_from_sfnt_stream'. 2008-10-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Set *is_sfnt_cid to FALSE if neither `CID ' nor `TYP1' is found in the sfnt container. 2008-10-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * include/freetype/config/ftconfig.h: Define FT_MACINTOSH when SC or MrC compiler of MPW is used. These compilers do not define the macro __APPLE__ by themselves. * builds/unix/ftconfig.in: Ditto. * builds/vms/ftconfig.h: Ditto. * src/base/ftbase.c: Use FT_MACINTOSH instead of __APPLE__, to include ftmac.c if FreeType 2 is built by MPW. * src/base/ftobjs.c: Use FT_MACINTOSH instead of __APPLE__, to enable shared functions for ftmac.c if FreeType 2 is built by MPW. * builds/mac/ftmac.c: Include ftbase.h.

(memory_stream_close): Build on any platform when old MacOS font support is enabled. (new_memory_stream): Ditto. (open_face_from_buffer): Build on any platform when old MacOS font support is enabled. The counting of the face in a font file is slightly different between Carbon-dependent parser and Carbon-free parser. They are merged with the platform-specific conditional. (ft_lookup_PS_in_sfnt): Ditto. * src/base/ftmac.c: Include ftbase.h. (memory_stream_close): Removed. (new_memory_stream): Ditto. (open_face_from_buffer): Removed. Use the implementation in ftobjs.c.

Reported by Graham Asher. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/rules.mk: Add conditional source to BASE_SRC, for `make multi' on Mac OS X. If the macro $(ftmac_c) is defined, $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes ftmac.c. * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c). * builds/unix/configure.raw: Add procedure to set up appropriate value of $(ftmac_c) with the consideration of the availability of Carbon framework. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/Jamfile: Add target for multi build by jam on Mac OS X. * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this function for MPW building.

(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID ' table in sfnt table directory. It is used before loading TrueType font driver. * docs/CHANGES: Add note about the current status of sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support. 2008-09-18 Werner Lemberg <wl@gnu.org> * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for orthogonality (ft_free and ft_sfree could belong to different memory pools). This fixes Savannah bug #24297. 2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined in tttags.h instead of numerical value 0x4F54544FL. 2008-09-16 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.h, src/cff/cffgload.c (cff_decoder_set_width_only): Eliminate function call. 2008-09-15 George Williams <gww@silcom.com> Fix Savannah bug #24179, reported by Bram Tassyns. * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation of default values. 2008-09-15 Werner Lemberg <wl@gnu.org> * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index' and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to prevent unconditional definition. This fixes Savannah bug #24241. * src/psnames/pstables.h: Regenerated. 2008-09-13 Werner Lemberg <wl@gnu.org> * autogen.sh, builds/unix/configure.raw, include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor beautifying. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h, include/freetype/ftlcdfil.h: Protect against FreeType 1.

(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp computation is disabled and the statically configured sizes are used. This fixes Savannah bug #21250. * builds/unix/configure.raw: Add the checks to compare the cpp computation results of the bit length of int and long versus the sizes detected by running `configure'. If the results are different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the results. New option --{enable|disable}-biarch-config is added to define or undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually. 2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or ApplicationServices framework is missing. Although this value is not used in building of FreeType2, it is written in `freetype2.pc' and `freetype-config'. 2008-09-01 David Turner <david@freetype.org> * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap index to mean `use default cached FT_Face's charmap'. This fixes Savannah bug #22625. * include/freetype/ftcache.h: Document it. Make FT_MulFix an inlined function. This is done to speed up FreeType a little (on x86 3% when loading+hinting, 10% when rendering, ARM savings are more important though). Disable this by undefining FT_CONFIG_OPTION_INLINE_MULFIX. Use of assembler code can now be controlled with FT_CONFIG_OPTION_NO_ASSEMBLER. * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler implementation. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler implementation taken from `ftcalc.c'. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro which is defined to the platform-specific assembler implementation of FT_MulFix. [FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER] (FT_MULFIX_INLINED): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER, FT_CONFIG_OPTION_INLINE_MULFIX): New macros. * include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED. * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and FT_MULFIX_INLINED. Add a new header named FT_ADVANCES_H declaring some new APIs to extract the advances of one or more glyphs without necessarily loading their outlines. Also provide `fast loaders' for the TrueType, Type1, and CFF font drivers (more to come later). * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files. * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro. * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro. * include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc): `flags' and `advances' are now of type `FT_UInt' and `FT_Fixed', respectively. * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add ftadvanc.c. * src/cff/cffdrivr.c (cff_get_advances): New function. (cff_driver_class): Register it. * src/cff/cffgload.c (cff_decoder_set_width_only): New function. (cff_decoder_parse_charstrings): Handle `width_only'. (cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY. * src/cff/cffgload.h (cff_decoder): New element `width_only'. (cff_decoder_set_width_only): New declaration. * src/truetype/ttdriver.c (tt_get_advances): New function. (tt_driver_class): Register it. * src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to... (TT_Get_HMetrics, TT_Get_VMetrics): This. Update callers. * src/truetype/ttgload.h: Declare them. * src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New function. * src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances. Add checks for minimum version of the `autotools' stuff. * autogen.sh: Implement it. (get_major_version, get_minor_version, get_patch_version, compare_to_minimum_version, check_tool_version): New auxiliary functions. * README.CVS: Document it. 2008-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in tttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ). 2008-08-28 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_encoding): Protect against infinite loop. This fixes Savannah bug #24150 (where a patch has been posted too). 2008-08-23 Werner Lemberg <wl@gnu.org> * src/type/t1afm.c (compare_kern_pairs), src/psaux/afmparse.c (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug #24119. 2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always, even if passed library or arguments are invalid. This fixes a bug that an uninitialized stream is freed when an invalid library handle is passed. Originally proposed by Mike Fabian, 2008/08/18 on freetype-devel. (FT_Open_Face): Ditto (stream). (load_face_in_embedded_rfork): Ditto (stream2). 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c: Add a fallback to guess the availability of the `ResourceIndex' type. It is used when built without configure (e.g., a build with Jam). * builds/mac/ftmac.c: Ditto. * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0 explicitly, even if `ResourceIndex' is unavailable. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: In checking of Mac OS X features, all-in-one header file `Carbon.h' is replaced by the minimum header file `CoreServices.h', similar to current src/base/ftmac.c. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of sub-header when its code_count is 0. Many Japanese Dynalab fonts include such an empty sub-header (code_count == 0, first_code == 0 delta == 0, but offset != 0) as the second sub-header in SJIS cmap. 2008-08-04 Werner Lemberg <wl@gnu.org> * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes Savannah bug #23995. * src/cid/cidload.c (parse_expansion_factor): New callback function. (cid_field_records): Use it for `ExpansionFactor'. * src/cod/cidtoken.h: Handle `ForceBold' keyword. Don't handle `ExpansionFactor'. 2008-08-04 Bram Tassyns <bramt@enfocus.be> * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which resulted in incorrect scaling. This fixes Savannah bug #23973. 2008-08-04 Werner Lemberg <wl@gnu.org> Be more tolerant w.r.t. invalid entries in SFNT table directory. * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and adjust table count. Add more trace messages. (tt_face_load_font_dir): Updated. 2008-07-30 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer assume that the first argument on the stack is the bottom-most element. Two reasons: o According to people from Adobe it is missing in the Type 2 specification that pushing of additional, superfluous arguments on the stack is prohibited. o Acroread in general handles fonts differently, namely by popping the number of arguments needed for a particular operand (as a PS interpreter would do). In case of buggy fonts this causes a different interpretation which of the elements on the stack are superfluous and which not. Since there are CFF subfonts (embedded in PDFs) which rely on Acroread's behaviour, FreeType now does the same. 2008-07-27 Werner Lemberg <wl@gnu.org> Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This fixes Savannah bug #23940. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to... (EXTRA_GLYPH_LIST_SIZE): This. Increase by 2. (ft_wgl_extra_unicodes): Rename to... (ft_extra_glyph_unicodes): This. Add two code values. (ft_wgl_extra_glyph_names): Rename to... (ft_extra_glyph_names): This. Add two glyphs. (ft_wgl_extra_glyph_name_offsets): Rename to... (ft_extra_glyph_name_offsets): This. Add two offsets. (ps_check_wgl_name, ps_check_wgl_unicode): Rename to... (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This. Updated. (ps_unicodes_init): Updated. 2008-07-26 Werner Lemberg <wl@gnu.org> * src/cff/cffgload.c (cff_decoder_prepare, cff_decoder_parse_charstrings): Improve debug output. 2008-07-22 Martin McBride <mmcbride@emtex.com> * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): Handle fonts which treat the last segment specially. According to the specification, such fonts would be invalid but acroread accepts them. 2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk> * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error. * src/base/ftcalc.c (FT_MulFix): Fix portability issue. * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]: Fix compiler warning. 2008-07-16 Werner Lemberg <wl@gnu.org> Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly. * src/cff/cffload.c (cff_font_load): Pass `pure_cff'. Invert sids table only if `pure_cff' is set. * src/cff/cffload.h: Updated. * src/cff/cffobjs.c (cff_face_init): Updated. Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set. * docs/CHANGES: Updated. 2008-07-09 Werner Lemberg <wl@gnu.org> * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts where num_locations < num_glyphs. Problem reported by Ding Li. 2008-07-05 Werner Lemberg <wl@gnu.org> Since FreeType uses `$(value ...)', we now need GNU make 3.80 or newer. This fixes Savannah bug #23648. * configure: zsh doesn't like ${1+"$@"}. Update needed GNU make version. * builds/toplevel.mk: Check for `$(eval ...)'. * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document it. 2008-07-04 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one pixel, only check for dropouts if neither start nor end point lies on a pixel center. This fixes Savannah bug #23762. 2008-06-29 Werner Lemberg <wl@gnu.org> * Version 2.3.7 released. ========================= Tag sources with `VER-2-3-7'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.7. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7. * builds/unix/configure.raw (version_info): Set to 9:18:3. * docs/release: Updated. 2008-06-28 Werner Lemberg <wl@gnu.org> * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to... * src/ftcalc.c: Here. This fixes Savannah bug #23729. 2008-06-27 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Test for intersections which degenerate to a single point can be ignored; this has been confirmed by Greg Hitchcock from Microsoft. (This was commented out code.) 2008-06-26 Werner Lemberg <wl@gnu.org> Improve navigation in API reference. * src/tools/docmaker/tohtml.py (html_header_3): Renamed to... (html_header_6): This. (html_header_3, html_header_3i, html_header_4, html_header_5, html_header_5t): New strings. (toc_footer_start, toc_footer_end): New strings. (HtmlFormatter::html_header): Updated. (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header): New strings. (HtmlFormatter::index_enter): Use `html_index_header'. (HtmlFormatter::index_exit): Print `html_footer'. (HtmlFormatter::toc_enter): Use `html_toc_header'. (HtmlFormatter::toc_exit): Print proper footer. Convert ~ to non-breakable space. * src/tools/docmaker/tohtml.py (make_html_para): Implement it. Update header files accordingly. 2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Check type `ResourceIndex' explicitly and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5 bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without ResourceIndex type definition. The macro does not inform the type availability. * src/base/ftmac.c: More parentheses are inserted to clarify the conditionals to disable legacy APIs in `10.5 and later' cases. If HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined. 2008-06-24 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering mode. * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph, Draw_Sweep): No-dropout mode is value 2, not value 0. (Draw_Sweep): Really skip dropout handling for no-dropout mode. 2008-06-24 Werner Lemberg <wl@gnu.org> * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour if it consists of one point only. Based on a patch from Savannah bug #23683 (from John Tytgat). 2008-06-22 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff with IS_HINTED. * docs/CHANGES: Updated. 2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option but LDFLAGS does not, import it to LDFLAGS. The option is used to specify non-default SDK on Mac OS X (e.g., universal binary SDK for Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137 recommends to add the option only to CFLAGS, LDFLAGS should include it because libfreetype.la is built with -no-undefined. This fixes a bug reported by Ryan Schmidt in MacPorts, https://trac.macports.org/ticket/15331. 2008-06-21 Werner Lemberg <wl@gnu.org> Enable access to the various dropout rules of the B&W rasterizer. Pass dropout rules from the TT bytecode interpreter to the rasterizer. * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS, FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop, Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the OpenType specification. Fix mode 4 computation. (Render_Glyph, Render_Gray_Glyph): Handle new outline flags. * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion mode to FT_OUTLINE_XXX flags. * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check. 2008-06-19 Werner Lemberg <wl@gnu.org> * src/cff/cffobjs.c (cff_face_init): Compute final `dict->units_per_em' value before assigning it to `cffface->units_per_EM'. Otherwise, CFFs without subfonts are scaled incorrectly if the font matrix is non-standard. This fixes Savannah bug #23630. * docs/CHANGES: Updated. 2008-06-19 Werner Lemberg <wl@gnu.org> * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix from 2008-06-19. 2008-06-18 Werner Lemberg <wl@gnu.org> * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21. Reported by Peter Weilbacher <mozilla@weilbacher.org>. * docs/CHANGES: Updated. 2008-06-15 George Williams <gww@silcom.com> * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set `valid->extra2' to 1. This is undocumented in the OpenType 1.5 specification. 2008-06-15 Werner Lemberg <wl@gnu.org> * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly from clobbering. Patch from Savannah bug report #23556. * docs/CHANGES: Document it. 2008-06-10 Werner Lemberg <wl@gnu.org> * autogen.sh: Add option `--install' to libtoolize. 2008-06-10 Werner Lemberg <wl@gnu.org> * Version 2.3.6 released. ========================= Tag sources with `VER-2-3-6'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.6. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6. * builds/unix/configure.raw (version_info): Set to 9:17:3. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x' and `scale_y'. * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'. * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H. * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H. 2008-06-10 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (open_face): Check `clazz->init_face' and `clazz->done_face'. 2008-06-09 VaDiM <s_sliva@rambler.ru> Support debugging on WinCE. From Savannah patch #6536; this fixes bug #23497. * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro as a replacement for OutputDebugStringA (which WinCE doesn't have). Update all callers. (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have environment variables. 2008-06-09 Werner Lemberg <wl@gnu.org> * README.CVS: Updated. * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated for newer versions of autoconf and friends. 2008-06-08 Werner Lemberg <wl@gnu.org> * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and `private_len' unsigned. * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read it as such. (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned. * src/base/ftstream.c (FT_Stream_Skip): Reject negative values. * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis' for sane value. Fix typo. * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly. * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check `last_point'. * src/sfnt/ttload.c (tt_face_load_max_profile): Limit `maxTwilightPoints'. 2008-06-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0' correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem. 2008-06-03 Werner Lemberg <wl@gnu.org> * include/freetype/ftcache.h (FTC_FaceID): Change type back to FT_Pointer. Reported by Ian Britten <britten@caris.com>. 2008-06-02 Werner Lemberg <wl@gnu.org> Emit header info for defined FreeType objects in reference. * src/tools/docmaker/content.py (re_header_macro): New regexp. (ContentProcessor::__init__): Initialize new dictionary `headers'. (DocBlock::__init__): Collect macro header definitions. * src/tools/docmaker/tohtml.py (header_location_header, header_location_footer): New strings. (HtmlFormatter::__init__): Pass `headers' dictionary. (HtmlFormatter::print_html_field): Don't emit paragraph tags. (HtmlFormatter::print_html_field_list): Emit empty paragraph. (HtmlFormatter::block_enter): Emit header info. 2008-06-01 Werner Lemberg <wl@gnu.org> * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H, FT_INCREMENTAL_H): Added. 2008-05-28 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/sources.py (SourceBlock::__init__): While looking for markup tags, return immediately as soon a single one is found. 2008-05-28 Werner Lemberg <wl@gnu.org> * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses original, unscaled input values. Confirmed by Greg Hitchcock from Microsoft. 2008-05-27 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py (block_footer_start, block_footer_middle): Beautify output. 2008-05-25 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (fc_black_render): Return 0 when we are trying to render into a zero-width/height bitmap, not an error code. * src/truetype/ttgload.c (load_truetype_glyph): Move initialization of the graphics state for subglyphs to... (TT_Hint_Glyph): This function. Hinting instructions for a composite glyph apparently refer to the just hinted subglyphs, not the unhinted, unscaled outline. This seems to fix Savannah bugs #20973 and (at least partially) #23310. 2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid `aface' is returned by FT_New_Face_From_FOND(). The patch was proposed by an anonymous reporter of Savannah bug #23204. 2008-05-18 Werner Lemberg <wl@gnu.org> * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after correction for pixel boundary. Without this patch, the effect can be cumulative under certain circumstances, making glyphs taller and taller after each call. This fixes Savannah bug #19976. 2008-05-18 Werner Lemberg <wl@gnu.org> * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr. This fixes Savannah bug #23280. * docs/CHANGES: Updated. 2008-05-18 David Turner <david@freetype.org> * src/psnames/psmodule.c (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets, ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make declarations non-global. * src/type1/t1load.c: Add missing comment. 2008-05-17 Sam Hocevar <samh> * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour glyphs correctly. Patch from Savannah bug #23277. 2008-05-16 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-05-16 Sergey Tolstov <stolstov@esri.com> Improve support for WGL4 encoded fonts. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.

Reported by Martin McBride. 2008-05-15 Werner Lemberg <wl@gnu.org> * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated. 2008-05-15 Werner Lemberg <wl@gnu.org> * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array which contains a single but empty entry. This is technically invalid (since it must end with `return'), but... Reported by Martin McBride. 2008-05-14 Werner Lemberg <wl@gnu.org> Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function. (cff_parse_font_matrix): Use it. * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em' FT_ULong. * docs/CHANGES: Document it. 2008-05-13 Werner Lemberg <wl@gnu.org> * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init): Handle case `face_index < 0'. * docs/CHANGES: Document it. 2008-05-04 Werner Lemberg <wl@gnu.org> First steps to fix the scaling bug of CID-keyed CFF subfonts, reported by Ding Li on 2008/03/28 on freetype-devel. * src/base/cff/cffparse.c (power_tens): New array.

(cff_parse_fixed_thousand): Replace with... (cff_parse_fixed_scaled): This function. Update all callers. 2008-05-03 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without transformation since it recursively calls FT_Load_Glyph. This fixes Savannah bug #23143. 2008-04-26 Werner Lemberg <wl@gnu.org> * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/psaux/psobjs.c (t1_builder_init): Updated. * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/cff/cffgload.c (cff_builder_init): Updated. 2008-04-14 Werner Lemberg <wl@gnu.org> * src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to `FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZW'. From Savannah bug #22909. 2008-04-13 Werner Lemberg <wl@gnu.org> * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if integer part is zero. 2008-04-01 Werner Lemberg <wl@gnu.org> Fix compilation with g++ 4.1 (with both `single' and `multi' targets). * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block which is crossed by a `goto'. * src/otvalid/otvalid.h (otv_MATH_validate): Add prototype. 2008-03-31 Werner Lemberg <wl@gnu.org> Fix support for subsetted CID-keyed CFFs. * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED, FT_IS_CID_KEYED): New macros. * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the maximum CID value in CID-keyed CFFs. Handle FT_FACE_FLAG_CID_KEYED flag. * docs/CHANGES: Document it. Fix CFF font matrix calculation and improve precision. * src/cff/cffparse.c (cff_parse_real): Increase precision if integer part is zero. (cff_parse_font_matrix): Simplify computation of `units_per_em'; this prevents overflow also. Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts. * src/cid/cidriver.c: Include FT_SERVICE_CID_H. (cid_get_ros): New function. (cid_service_cid_info): New service structure. (cid_services): Register it. 2008-03-23 Werner Lemberg <wl@gnu.org> Adjustments for Visual C++ 8.0, as reported by Rainer Deyke. * builds/compiler/visualc.mk (CFLAGS): Remove /W5. (ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE. 2008-03-21 Laurence Darby <ldarby> * src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from Savannah bug #22675. 2008-03-13 Derek Clegg <dclegg@apple.com> * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop. Patch from Savannah bug #22541. 2008-03-03 Masatoshi Kimura <VYV03354@nifty.ne.jp> * src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant): Return correct value. (tt_cmap14_variant_chars): Fix check for `di'. 2008-02-29 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2008-02-29 Wolf Add build support for symbian platform. From Savannah bug #22440. * builds/symbian/*: New files. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name synthesis. For any face of a specified FOND, always the name for the first face was used. Except of a FOND that refers multiple Type1 font files, wrong synthesized font names are not used at all, so this is an invisible bug. A few limit checks are added too. * builds/mac/ftmac.c: Ditto. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Split compiler option to link Carbon frameworks to one option for CoreServices framework and another option for ApplicationServices framework. The split options can be managed by GNU libtool to avoid unrequired duplication when FreeType is linked with other applications. Suggested by Daniel Macks, Savannah bug #22366. 2008-02-18 Victor Stinner <victor.stinner@haypocalc.com> * src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix from Savannah bug #22356. 2008-02-17 Jonathan Blow <jon@number-none.com> * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph): Check for valid callback pointers. 2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource handle by its value instead of ResError(), fix provided by Deron Kazmaier. According to the Resource Manager Reference, GetResource(), Get1Resource(), GetNamedResource(), Get1NamedResource() and RGetResource() set noErr but return NULL handle when they can not find the requested resource. These functions never return undefined values, so it is sufficient to check if the handle is not NULL. * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto. 2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other inclusion styles. Now it always includes src/base/ftmac.c; builds/mac/ftmac.c is never included in any configuration. * builds/unix/configure.raw: Print warning if configure is executed with options to specify Carbon functionalities explicitly. * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not included automatically and manual replacement is required. 2008-02-11 Werner Lemberg <wl@gnu.org> * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk (dos_setup), builds/freetype.mk (clean_project_dos, distclean_project_dos): Don't use \ but $(SEP). Reported by Duncan Murdoch. 2008-01-18 Sylvain Pasche <sylvain.pasche@gmail.com> * src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to mention intra-pixel algorithm. * include/freetype/freetype.h (FT_Render_Mode): Mention that FT_Library_SetLcdFilter can be used to reduce fringes. 2008-01-16 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (ft_black_render): Check `outline' before using it. Reported by Allan Yang. 2008-01-12 Werner Lemberg <wl@gnu.org> * src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove. 2008-01-12 Allan Yang, Jian Hua - SH <Allan.Yang@fmc.fujitsu.com> * src/raster/ftraster.c (ft_black_init) [FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation. 2008-01-10 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Handle the case where the number of contours in a simple glyph is zero (and which does contain an entry in the `glyf' table). This fixes Savannah bug #21990. 2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Formatting suggested by Sean McBride. * builds/mac/ftmac.c: Formatting (tab expanded). * src/autofit/afindic.c: Ditto. * src/base/ftcid.c: Ditto. * src/base/ftmac.c: Ditto. 2007-12-30 Werner Lemberg <wl@gnu.org> * src/smooth/ftgrays.c (gray_raster_render): Check `outline' correctly. 2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Improvement of POSIX resource-fork accessor to load unsorted references in a resource. In HelveLTMM (resource-fork PostScript Type1 font bundled with Mac OS X since 10.3.x), the appearance order of PFB chunks is not sorted; sorting the chunks by reference IDs is required. * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure type to store a pair of reference ID and offset to the chunk. * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to sort FT_RFork_Ref by their reference IDs. (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is sorted by reference ID. 2007-12-14 Werner Lemberg <wl@gnu.org> * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten' division too early; otherwise the most significant digit(s) of the final result are lost as the value is truncated to an integer. This fixes Savannah bug #21794 (where the patch has been posted too). 2007-12-06 Fix <4d876b82@gmail.com> Pass options from one configure script to another as-is (not expanded). This is needed for options like --includedir='${prefix}/include'. * builds/unix/detect.mk, configure: Prevent argument expansion in call to the (real) `configure' script. 2007-12-06 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if TT_USE_BYTECODE_INTERPRETER isn't defined. 2007-12-06 Werner Lemberg <wl@gnu.org> There exist CFFs which contain opcodes for the Type 1 operators `hsbw' and `closepath' which are both invalid in Type 2 charstrings. However, it doesn't harm to support them. * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and `cff_op_closepath.' (cff_argument_counts): Ditto. (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath) and 13 (hsbw) which are invalid in Type 2 charstrings. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to support new pathname syntax `..namedfork/rsrc' to access a resource fork on Mac OS X. The legacy syntax `/rsrc' does not work on case-sensitive HFS+. (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of buffer size to store a pathname. * include/freetype/internal/ftrfork.h: Increment the number of resource fork guessing rule. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Improve the compile tests to search Carbon functions. * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16). 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> The documents and comments for Mac OS X are improved by Sean McBride. * src/base/ftmac.c: Fix a comment. * include/freetype/ftmac.h: Ditto. * docs/INSTALL.MAC: Improve English and add comment on lowest system version specified by MACOSX_DEPLOYMENT_TARGET. 2007-12-04 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to concatenate error codes. * src/sfnt/ttsbit.c (Load_SBit_Range): Ditto. 2007-12-04 Graham Asher <graham.asher@btinternet.com> * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to concatenate error codes. 2007-12-04 Sean McBride <sean@rogue-research.com> * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler warning. 2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is not working since 2.3.5. In FT_Open_New(), if FT_New_Stream() cannot mmap() the specified file and cannot seek to head of the specified file, it returns NULL stream and FT_Open_New() returns the error immediately. On MacOS, most legacy MacOS fonts fall into such a scenario because their data forks are zero-sized and cannot be sought. To proceed to guessing of resource fork fonts, the functions for legacy MacOS font must properly handle the NULL stream returned by FT_New_Stream(). * src/base/ftobjs.c (IsMacBinary): Return error FT_Err_Invalid_Stream_Operation immediately when NULL stream is passed. (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed to fallback. Originally, legacy MacOS font is tested in the cases of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty) or FT_Err_Unknown_File_Format (occurs when AppleSingle header or .dfont header is combined). Now the case of FT_Err_Cannot_Open_Stream is included. * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL, skip FT_Stream_Seek(), which seeks to the head of stream, and proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek() for a NULL stream causes a Bus error on Mac OS X. (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream immediately if passed stream is NULL. (raccess_guess_apple_single): Ditto. 2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Fix for Carbon incompatibilities since Mac OS X 10.5, proposed by Sean McBride. * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET. * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling Carbon functions from a forked process is classified as unsafe by Apple. All Carbon-dependent functions should be deprecated. * src/base/ftmac.c: Use essential header files <CoreServices/CoreServices.h> and <ApplicationServices/ApplicationServices.h> instead of all-in-one header file <Carbon/Carbon.h>. Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple genuine macro PATH_MAX. Add fallback macro for kATSOptionFlagsUnRestrictedScope which is not found in Mac OS X 10.0. Multi-character constants ('POST', 'sfnt' etc) are replaced by 64bit constants calculated by FT_MAKE_TAG() macro. For the index in the segment of resource fork, new portable type ResourceIndex is introduced for better compatibility. This type is since Mac OS X 10.5, so it is defined as short when built on older platforms. (FT_ATSFontGetFileReference): If build target is only the systems 10.5 and newer, it calls Apple genuine ATSFontGetFileReference(). (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5 and newer or 64bit platform, because legacy type FSSpec type is removed completely. (FT_New_Face_From_FSSpec): Ditto. 2007-11-01 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This fixes Savannah bug #21485. 2007-10-29 Daniel Svoboda <dasvo@planeta@cz> * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver can handle the font at all, then check `face_index'. Otherwise, the driver might return the wrong error code. This fixes Savannah bug #21468. 2007-10-21 Werner Lemberg <wl@gnu.org> * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare support for bit 8 of the `fsSelection' field in the `OS/2' table. MS is already using this; hopefully, this becomes part of OpenType 1.5. Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22 (WWS_SUBFAMILY). 2007-10-20 Werner Lemberg <wl@gnu.org> * src/tools/docmaker/tohtml.py (html_header_2): Fix typo. Add `td.left' element to CSS. (toc_section_enter): Use it. 2007-10-18 David Turner <david@freetype.org> * include/freetype/freetype.h, src/base/ftobjs.c: Rename API functions related to cmap type 14 support to the `FT_Object_ActionName' scheme: FT_Get_Char_Variant_Index -> FT_Face_GetCharVariantIndex FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault FT_Get_Variant_Selectors -> FT_Face_GetVariantSelectors FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant Update documentation accordingly. * src/sfnt/ttcmap.c: Stronger cmap 14 validation. Make the code a little more consistent with FreeType coding conventions and modify the cmap14 functions that returned a newly allocated array to use a persistent vector from the TT_CMap14 object instead. (TT_CMap14Rec): Provide array and auxiliary data for result. (tt_cmap14_done, tt_cmap14_ensure): New functions. (tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary, tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant, tt_cmap14_char_var_index, tt_cmap14_variants, tt_cmap14_char_variants, tt_cmap14_def_char_count, tt_cmap14_get_def_chars, tt_cmap14_get_nondef_chars, tt_cmap14_variant_chars, tt_cmap14_class_rec): Updated and improved. 2007-10-15 George Williams <gww@silcom.com> Add support for cmap type 14. * devel/ftoption.h, include/freetype/config/ftoption.h (TT_CONFIG_CMAP_FORMAT_14): New macro. * include/freetype/internal/ftobjs.h (FT_CMap_CharVarIndexFunc, FT_CMap_CharVarIsDefaultFunc, FT_CMap_VariantListFunc, FT_CMap_CharVariantListFunc, FT_CMap_VariantCharListFunc): New support function prototypes. (FT_CMap_ClassRec): Add them. Update all users. * include/freetype/ttnameid.h (TT_APPLE_ID_VARIANT_SELECTOR): New macro. * include/freetype/freetype.h (FT_Get_Char_Variant_Index, FT_Get_Char_Variant_IsDefault, FT_Get_Variant_Selectors, FT_Get_Variants_Of_Char, FT_Get_Chars_Of_Variant): New API functions. * src/base/ftobjs.c (find_variant_selector_charmap): New auxiliary function. (FT_Set_Charmap): Disallow cmaps of type 14. (FT_Get_Char_Variant_Index, FT_Get_Char_Variant_IsDefault, FT_Get_Variant_Selectors, FT_Get_Variants_Of_Char, FT_Get_Chars_Of_Variant): New API functions. * src/sfnt/ttcmap.c (TT_PEEK_UINT24, TT_NEXT_UINT24): New macros. (TT_CMap14Rec, tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_index, tt_cmap14_char_next, tt_cmap14_get_info, tt_cmap14_char_map_def_binary, tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant, tt_cmap14_char_var_index, tt_cmap14_char_var_isdefault, tt_cmap14_variants, tt_cmap14_char_variants, tt_cmap14_def_char_count, tt_cmap14_get_def_chars, tt_cmap14_get_nondef_chars, tt_cmap14_variant_chars, tt_cmap14_class_rec): New functions and structures for cmap 14 support. (tt_cmap_classes): Register tt_cmap14_class_rec. (tt_face_build_cmaps): One more error message. * docs/CHANGES: Mention cmap 14 support. 2007-10-01 Werner Lemberg <wl@gnu.org> * src/base/ftobjs.c (find_unicode_charmap): If search for a UCS-4 charmap fails, do the loop again while searching a UCS-2 charmap. This favours MS charmaps over Apple ones. 2007-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c: Introduction of abstract `short' data types, ResFileRefNum and ResID. These types were introduced for Copland, then backported to MPW. The variables exchanged with FileManager QuickDraw frameworks are redefined by these data types. Patch was proposed by Sean McBride. * builds/mac/ftmac.c: Ditto. 2007-08-18 Werner Lemberg <wl@gnu.org> * src/otvalid/otvcommn.c (otv_x_y_ux_sy): Skip context glyphs. Found by Imran Yousaf. Fixes Savannah bug #20773. (otv_Lookup_validate): Correct handling of LookupType. Found by Imran Yousaf. Fixes Savannah bug #20782. 2007-08-17 George Williams <gww@silcom.com> * src/otvalid/otvgsub.c (otv_SingleSubst_validate): Fix handling of SingleSubstFormat1. 2007-08-11 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * builds/unix/configure.raw: Fix a bug which sets CC_BUILD by ${build-gcc} (unchecked) instead of by ${build}-gcc (checked). Found by Ryan Hill. 2007-08-11 George Williams <gww@silcom.com> * src/otvalid/otvcommn.c, src/otvalid/otvcommn.h (otv_Coverage_validate): Add fourth argument to pass an expected count value.

Reported by Graham Asher. 2007-07-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (open_face_from_buffer): The argument `driver_name' is typed as `const char*' to match with the callers in FT_New_Face_From_LWFN and FT_New_Face_From_SFNT. This is same with open_face_from_buffer in src/base/ftobjs.c.

We need to close all faces before destroying the modules, or else some bad things (memory leaks) may happen. 2007-01-02 Werner Lemberg <wl@gnu.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): Remove compiler warning. 2007-01-02 David Turner <david@freetype.org> * src/sfnt/sfobjs.c: Add documentation comment. 2006-12-31 Masatake YAMATO <jet@gyve.org> * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New function.

This fixes Savannah bug #16914. 2006-06-26 Jens Claudius <jens.claudius@yahoo.com> * src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15. (t1_decoder_parse_charstrings): Operator with opcode 15 pops its two arguments. Handle the case where the pops of an othersubr may be part of a subroutine. Handle unknown othersubrs gracefully: count their operands and let the following pop operators push the operands as the results onto the Type1 stack. Improve handling of setcurrentpoint opcode. 2006-06-25 Jens Claudius <jens.claudius@yahoo.com> The Type 1 parser now skips over top-level procedures as required for a `Simplified Parser'. This makes the parser more robust as it doesn't poke around in PostScript code. Additionally, it makes the FontDirectory hackery in src/type1/t1load.c unnecessary. * src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro. (skip_literal_string): Add FT_Error as return value.

(count_faces): Call `HUnlock' after all FOND utilization. 2006-06-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Public API of TrueTypeGX, OpenType, and classic kern table validator should return `FT_Err_Unimplemented_Feature' if validation service is unavailable (disabled in `modules.cfg'). It is originally suggested by David Turner, cf. https://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html * src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return FT_Err_Unimplemented_Feature if TrueTypeGX validation service is unavailable. (FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if classic kern table validation service is unavailable. * src/base/ftotval.c (FT_OpenType_Validate): Return FT_Err_Unimplemented_Feature if OpenType validation service is unavailable. 2006-06-08 Werner Lemberg <wl@gnu.org> * src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of errors. 2006-06-07 David Turner <david@freetype.org> * src/type1/t1afm.c (KERN_INDEX): Make it more robust.

This fixes Savannah bug #16768. 2006-06-06 David Turner <david@freetype.org> Fix memory leak described in Savannah bug #16759. We change `ps_unicodes_init' so that it also takes a `free_glyph_name' callback to release the glyph names returned by `get_glyph_name' * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc): Renamed to ... (PS_GetGlyphNameFunc): This. (PS_FreeGlyphNameFunc): New typedef. (PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc. * src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first argument. (cff_sid_free_glyph_name): New function. (cff_cmap_unicode_init): Updated. * src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated. * src/psnames/psmodule.c (ps_unicodes_init): Add variable for PS_FreeGlyphNameFunc and use it. 2006-06-04 David Turner <david@freetype.org> * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept `item_size == 0' as well -- though this sounds weird, it can theoretically happen. This fixes Savannah bug #16669. * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation of `face->num_glyphs' which missed the last glyph, due to the offset-by-1 computation, since the PFR format doesn't guarantee that glyph index 0 corresponds to the `missing glyph. This fixes Savannah bug #16668. 2006-05-25 Werner Lemberg <wl@gnu.org> * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out `-no-undefined'. Reported by Christian Biesinger. 2006-05-19 Brian Weed <bw@imaginengine.com> * builds/win32/visualc/freetype.dsp: Release libraries no longer have debug information, and debug libraries use `C7 compatible' debug info. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> Apply patch by Derek Clegg to fix two memory leaks in the MacOS resource fork handler. This fixes Savannah bug #16631. * src/base/ftobjs.c (load_face_in_embedded_rfork): Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak. * src/base/ftrfork.c (raccess_guess_linux_double_from_file_name): Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * build/unix/configure.raw: Add a fallback to disable Carbon dependency, if configured with no options on Mac OS X. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> * src/base/ftmac.c (open_face_from_buffer): Deallocate stream when its content cannot be parsed as supported font. This fixes the second part of Savannah bug #16590. 2006-05-18 Werner Lemberg <wl@gnu.org> * src/truetype/ttgload.c (TT_Load_Composite_Glyph) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again. 2006-05-17 David Turner <david@freetype.org> This is a major patch used to drastically improve the performance of loading glyphs. This both speeds up loading the glyph vectors themselves and the auto-fitter module. We now use inline assembler code with GCC to implement `FT_MulFix', which is probably the most important function related to the engine's performance. The resulting speed-up is about 25%. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields `cursor' and `limit'. * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation): New functions. (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.

(FT_Stream_OpenGzip): Use it to handle small files directly in memory. * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Improve performance. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and `limit'. (TT_Load_Glyph_Header, TT_Load_Simple_Glyph, TT_Load_Composite_Glyph): Updated. Add threshold to protect against exceedingly large values of number of contours. Speed up by reducing the number of loops. * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold used to detect rogue clients from 4 to 16. This is to prevent some segmentation faults with fonts like `KozMinProVI-Regular.otf' which comes from the Japanese Adobe Reader Asian Font pack. 2007-05-17 Werner Lemberg <wl@gnu.org> * src/cff/cffload.c (cff_font_done): Deallocate subfont array. This fixes the first part of Savannah bug #16590. 2006-05-16 Werner Lemberg <wl@gnu.org> * docs/PROBLEMS: Updated icl issues. ---------------------------------------------------------------------------- Copyright 2006-2017 by David Turner, Robert Wilhelm, and Werner Lemberg.
