+2010-02-10 Ken Sharp <ken.sharp@artifex.com>
+
+ Really fix Savannah bug #28678 (part 2).
+
+ 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.

+ 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>

+
+ * 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_Loada_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.

+
+ [BDF] Modify hash API to take size_t value instead of void *.
+
+ 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). To reduce non-essential
+ casts from unsigned long to void* and from void* to unsigned
+ long, the hash API is changed to take size_t integer.
+ The issue of incompatible cast between unsigned long and void*
+ on LLP64 platform is reported by NightStrike from MinGW-Win64
+ project. See

+
+ Improve vertical metrics calculation (Savannah bug #27364).
+
+ 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. Vertical metrics
+ information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
+ was not defined.
+
+ * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
+ now calculated as described by the Adobe PDF Spec.

+ Use 16.16 format while parsing Type 1 charstrings.
+ 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.

+
+ Fix B/W rasterization of subglyphs with different drop-out modes.
+
+ 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.
+ (New_Profile): Set the drop-out mode in the profile's `flags' field.
+ (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
+ necessary.
+ (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.

+
+ * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
+
+2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
+
+ Fix handling of EBDT formats 8 and 9 (part 2).
+
+ 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.
+ Allocate bitmap.

+
+ 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.

+
+ 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.

+
+2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
+ sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
+ `open_face_from_buffer' frees the passed buffer if it cannot open a

+
+2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
+ for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
+ (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

+
+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,

+
+2008-09-11 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ * builds/unix/ftconfig.in: Duplicate the cpp computation of
+ FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
+ (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

+
+2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
+
+ * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
+ ApplicationService framework is missing. Although this value is not

+ `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

+ 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.

+ (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

+ * 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

+
+ * 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

+
+2008-08-28 Werner Lemberg <wl@gnu.org>
+
+ * src/type1/t1load.c (parse_encoding): Protect against infinite

+ too).
+
+2008-08-23 Werner Lemberg <wl@gnu.org>
+
+ * src/type/t1afm.c (compare_kern_pairs), src/pxaux/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'.

+ 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.

+
+ (ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
+ (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
+ 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/cff/cffload.h: Udpated.
+
+ * 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 ...)'.

+
+2008-07-04 Werner Lemberg <wl@gnu.org>
+
+ * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one

+ on a pixel center. This fixes Savannah bug #23762.
+
+2008-06-29 Werner Lemberg <wl@gnu.org>
+
+ * Version 2.3.7 released.

+
+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...

+ (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

+ 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,
+ http://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.

+
+ * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion

+
+ * 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>

+ 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'

+
+ * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
+
+
+ * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
+ `last_point'.

+ `maxTwilightPoints'.
+
+2008-06-06 Werner Lemberg <wl@gnu.org>
+
+ * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'

+
+2008-06-03 Werner Lemberg <wl@gnu.org>
+
+ * include/freetype/ftcache.h (FTC_FaceID): Change type back to

+
+ * 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>

+
+2008-05-17 Sam Hocevar <samh>

+
+2008-05-15 Werner Lemberg <wl@gnu.org>
+
+ * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
+ <op_closepath>: `closepath' without a path is a no-op, not an error

+
+ Reported by Martin McBride.

+
+ Reported by Martin McBride.
+
+2008-05-14 Werner Lemberg <wl@gnu.org>

+ (with proper scaling).
+
+ * src/cff/cffobjs.c (cff_make_private_dict): New function, using

+ (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;

+ and not correct.
+
+ * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
+

+2008-05-04 Werner Lemberg <wl@gnu.org>
+
+ First steps to fix the scaling bug of CID-keyed CFF subfonts,

+
+ * src/base/cff/cffparse.c (power_tens): New array.

+ (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

+ * 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

+
+ * 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

+
+2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

+
+ * builds/unix/configure.raw: Print warning if configure is executed

+
+ 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

+
+ * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure

+
+ * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to

+2007-12-14 Werner Lemberg <wl@gnu.org>
+
+ * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'

+
+ 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.

+ 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.

+ Tag sources with VER-2-3-1 to prepare release.
+
+ * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
+
+ * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
+ s/2.3.0/2.3.1/.
+
+ * builds/unix/configure.raw (version_info): Set to 9:12:3.
+
+
+ * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
+ (af_loader_load_g): Disable the warper (i.e., the light hinting
+ improvements) to make a 2.3.1 bugfix release before introducing a
+ new feature. This should give us more time to tune and improve the
+ warper for the next release.
+
+ * docs/CHANGES: Update accordingly.
+
+2007-01-25 David Turner <david@freetype.org>
+
+ For light auto-hinting, improve glyph advance widths and resurrect
+ normal/full hinting to its normal quality.
+

+
+2007-01-25 Werner Lemberg <wl@gnu.org>
+
+ * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
+ correctly in a sanity check. Since this function is only used to
+ load local and global functions, any charstring that called the last
+ local/global function would fail otherwise. This fixes Savannah bug
+ #18867.
+
+ * docs/CHANGES: Document it.
+
+2007-01-23 David Turner <david@freetype.org>
+
+ * src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that

+ large Asian CFF fonts.
+
+ * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
+ which happens when FT_Done_Library is called with still opened

+
+ This is a major patch used to drastically improve the performance of
+ loading glyphs. This both speeds up loading the glyph vectors

+
+ 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%.
+
+

+
+
+ * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
