63 Really fix Savannah bug #28678 (part 1).
65 After long discussion, we now consider the character width vector
66 (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
67 direction only. For example, if you are using the horizontal
68 writing direction, you get the horizontal and vertical components of
69 the advance width for this direction. Note that OpenType and CFF fonts
70 don't have such a vertical component; instead, the GPOS table can be
71 used to generate two-dimensional advance widths (but this isn't

154 Fix Savannah bug #28521.
156 Issue #28226 involved a work-around for a font which used the
157 `setcurrentpoint' operator in an invalid way; this operator is only
158 supposed to be used with the result of OtherSubrs, and the font used
159 it directly. The supplied patch removed the block of code which
160 checked this usage entirely.
162 This turns out to be a Bad Thing. If `setcurrentpoint' is being
163 used correctly it should reset the flex flag in the decoder. If we
164 don't do this then the flag never gets reset and we omit any further
165 contours from the glyph (at least until we close the path or

289 Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
290 This fixes Savannah bug #28226.
292 At least two wild PostScript files of unknown provenance contain
293 Type 1 fonts, apparently converted from TrueType fonts in earlier
294 PDF versions of the files, which use the `setcurrentpoint' operator
297 FreeType currently throws an error in this case, but Ghostscript and
298 Adobe Distiller both accept the fonts and ignore the problem. This
299 commit #ifdefs out the check so PostScript interpreters using
300 FreeType can render these files.
302 The specification says `setcurrentpoint' should only be used to set
303 the point after a `Subr' call, but these fonts use it to set the
304 initial point to (0,0). Unnecessarily so, as they correctly use an
305 `hsbw' operation which implicitly sets the initial point.

624 [BDF] Modify hash API to take size_t value instead of void *.
626 The hash API in BDF driver is designed to be generic, it takes
627 void * typed data. But BDF driver always gives an unsigned long
628 integer (the index to a property). To reduce non-essential
629 casts from unsigned long to void* and from void* to unsigned
630 long, the hash API is changed to take size_t integer.
631 The issue of incompatible cast between unsigned long and void*
632 on LLP64 platform is reported by NightStrike from MinGW-Win64
634 http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

644 size_t variable, with a cut-off at 256.
645 (bdf_get_property): Get the property id by size_t variable to
646 reduce the casts between 32-bit prop ID & hashnode->data during
648 (_bdf_add_property): Ditto.

679 Improve vertical metrics calculation (Savannah bug #27364).
681 The calculation of `vertBearingX' is not defined in the OTF font
682 spec so FreeType does a `best effort' attempt. However, this value
683 is defined in the PDF and PostScript specs, and that algorithm is
684 better than the one FreeType currently uses:
686 FreeType: Use the middle of the bounding box as the X coordinate
687 of the vertical origin.
689 Adobe PDF spec: Use the middle of the horizontal advance vector as
690 the X coordinate of the vertical origin.
692 FreeType's algorithm goes wrong if you have a really small glyph
693 (like the full-width, circle-like dot at the end of the sentence, as
694 used in CJK scripts) with large bearings. With the FreeType
695 algorithm this dot gets centered on the baseline; with the PDF
696 algorithm it gets the correct location (in the top right). Note
697 that this is a serious issue, it's like printing the dot at the end
698 of a Roman sentence at the center of the textline instead of on the
699 baseline like it should. So i believe the PDF spec's algorithm
700 should be used in FreeType as well.
702 The `vertBearingY' value for such small glyphs is also very strange
703 if no `vmtx' information is present, since the height of the bbox is
704 not representable for the height of the glyph visually (the
705 whitespace up to the baseline is part of the glyph). The fix also
706 includes some code for a better estimate of `vertBearingY'.
708 * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
709 is now calculated as described by the Adobe PDF Spec. Estimate for
710 `vertBearingY' now works better for small glyphs completely above or
711 below the baseline into account.
713 * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
714 calculated as described by the Adobe PDF Spec. Vertical metrics
715 information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
718 * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
719 now calculated as described by the Adobe PDF Spec.

835 * src/smooth/ftsmooth.c (ft_smooth_render_generic):
836 pitch and height are typed as FT_UInt but checked to fit
837 16-bit range, to avoid the overflows. On 16-bit system,
838 this checking inserts a conditional that never occurs.

1911 specific pathname syntax.
1912 * builds/compiler/bcc.mk: Remove unused flag, CCexe_LDFLAGS.

1948 smooth: Check glyph size by width/height, instead of pitch/height.
1949 Suggested by der Mouse <mouse@Rodents-Montreal.ORG>.
1951 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Improve
1952 the check for too large glyph. Replace the pair of `pitch' and
1953 `height' by the pair of `width' and `height'. `pitch' cannot

2053 an existing `modules.cfg' file in the build directory should be
2054 kept, not overwritten by the version in the source tree.
2056 2009-06-27 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2058 Filter --srcdir= option before invoking builds/unix/configure.
2060 * configure: If builds/unix/configure is invoked with --srcdir
2061 option, the option should take `builds/unix' directory instead of
2062 the top source directory. Thus the configure script in the top
2063 directory should modify the --srcdir= option if
2064 `builds/unix/configure' is invoked.

2099 Use 16.16 format while parsing Type 1 charstrings.
2100 This fixes Savannah bug #26867.
2102 Previously, only integers have been used which can lead to serious
2105 However, fractional values are only used internally; after the
2106 charstrings (of either Type 1 or 2) have been processed, the
2107 resulting coordinates get rounded to integers currently -- before
2108 applying scaling. This should be fixed; at the same time a new load
2109 flag should be introduced, to be used in combination with
2110 FT_LOAD_NO_SCALE, which indicates that font units are returned in
2111 16.16 format. Similarly, the incremental interface should be
2112 extended to allow fractional values for metrics.

2217 Fix B/W rasterization of subglyphs with different drop-out modes.
2219 Normally, the SCANMODE instruction (if present) to set the drop-out
2220 mode in a TrueType font is located in the `prep' table only and thus
2221 valid for all glyphs. However, there are fonts like `pala.ttf'
2222 which additionally contain this instruction in the hinting code of
2223 some glyphs (but not all). As a result it can happen that a
2224 composite glyph needs multiple drop-out modes for its subglyphs
2225 since the rendering state gets reset for each subglyph.
2227 FreeType collects the hinted outlines from all subglyphs, then it
2228 sends the data to the rasterizer. It also sends the drop-out mode
2229 -- after hinting has been applied -- and here is the error: It sends
2230 the drop-out mode of the last subglyph only; drop-out modes of all
2231 other subglyphs are lost.
2233 This patch fixes the problem; it adds a second, alternative
2234 mechanism to pass the drop-out mode: For each contour, the
2235 rasterizer now checks the first `tags' array element. If bit 2 is
2236 set, bits 5-7 contain the contour's drop-out mode, overriding the
2237 global drop-out mode.
2239 * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
2241 * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in

2247 (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
2249 (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
2250 Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
2253 2009-06-16 Werner Lemberg <wl@gnu.org>
2255 Improve scan conversion rules 4 and 6.
2257 Two new constraints are introduced to better identify a `stub' -- a
2258 concept which is only vaguely described in the OpenType
2259 specification. The old code was too rigorous and suppressed more
2260 pixel than it should.
2262 . The intersection of the two profiles with the scanline is less
2263 than a half pixel. Code related to this was already present in
2264 the sources but has been commented out.
2266 . The endpoint of the original contour forming a profile has a
2267 distance (`overshoot') less than half a pixel to the scanline.
2269 Note that the two additional conditions fix almost all differences
2270 to the Windows rasterizer, but some problematic cases remain.
2272 * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
2273 macros for the `flags' field in the `TProfile' structure.

2287 example, glyph `xi' in verdana.ttf at 13 ppem. Testing with ftbench
2288 on my GNU/Linux box I don't see a performance degradation.

3130 2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
3132 Fix handling of EBDT formats 8 and 9 (part 2).
3134 This patch fixes the following problems in ttsbit0.c:
3136 . Bitmaps for compound glyphs were never allocated.
3138 . `SBitDecoder' refused to load metrics if some other metrics have
3139 already been loaded. This condition certainly makes no sense for
3140 recursive calls, so I've just disabled it. Another possibility
3141 would be resetting `decoder->metrics_loaded' to false before
3142 loading each composite component. However, we must restore the
3143 original metrics after finishing the recursion; otherwise we can
3144 get a misaligned glyph.
3146 . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
3147 causing some glyph components to be shifted too far to the right
3148 (especially noticeable for small sizes).
3150 Note that support for grayscale bitmaps (not necessarily compound) is
3151 completely broken in ttsbit0.c.
3153 * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
3154 (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
3156 (tt_sbit_decoder_load_compound): Reset metrics after loading

3535 FT_USE_MODULE declares things as:
3537 extern const FT_Module_Class
3539 (or similar for C++). However, the actual types of the variables
3540 being declared are often different, e.g., FT_Driver_ClassRec or
3541 FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
3543 This works with most C compilers (since those structs begin with an
3544 FT_Module_Class struct), but technically it's undefined behavior.
3546 To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
3549 All declarations that refer to the same object or function shall
3550 have compatible type; otherwise, the behavior is undefined.
3552 (And they are not compatible types.)
3554 Most C compilers don't reject (or even detect!) code which has this
3555 issue, but the GCC LTO development branch compiler does. (It
3556 outputs the types of the objects while generating .o files, along
3557 with a bunch of other information, then compares them when doing the
3558 final link-time code generation pass.)

3614 Generalize the concept of `tricky' fonts by introducing
3615 FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
3616 engine is necessary for correct rendering.
3618 At the same time, slightly modify the behaviour of tricky fonts:
3619 FT_LOAD_NO_HINTING is now ignored. To really force raw loading
3620 of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
3621 FT_LOAD_NO_AUTOHINT must be used.
3623 Finally, tricky TrueType fonts always use the bytecode interpreter
3624 even if the patented code is used.

3648 a `glyf' table is missing.

3769 slot->internal == NULL. Reported by Graham Asher.
3771 2008-11-08 Werner Lemberg <wl@gnu.org>
3773 * src/sfnt/sfobjs.c (tt_face_get_name): Modified to return an error
3774 code so that memory allocation problems can be distinguished from
3775 missing table entries. Reported by Graham Asher.
3776 (GET_NAME): New macro.
3777 (sfnt_load_face): Use it.
3779 2008-11-05 Werner Lemberg <wl@gnu.org>

3782 [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Undefine
3783 TT_CONFIG_OPTION_UNPATENTED_HINTING. This fixes the return value of
3784 `FT_Get_TrueType_Engine_Type' (and makes it work as documented).
3785 Reported in bug #441638 of bugzilla.novell.com.
3787 * docs/CHANGES: Document it.
3789 2008-11-03 Werner Lemberg <wl@gnu.org>
3791 * src/type1/t1load.c (parse_subrs): Use an endless loop. There are
3792 fonts (like HELVI.PFB version 003.001, used on OS/2) which define
3793 some `subrs' elements more than once. Problem reported by Peter
3794 Weilbacher <mozilla@weilbacher.org>.
3796 2008-10-15 Graham Asher <graham.asher@btinternet.com>
3798 * src/sfnt/ttpost.c (tt_post_default_names): Add `const'.

3819 2008-10-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3821 Fix Savannah bug #24468.
3823 According to include/freetype/internal/ftobjs.h, the appropriate
3824 type to interchange single character codepoint is FT_UInt32. It
3825 should be distinguished from FT_UInt which can be 16bit integer.
3827 * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Change the type
3828 of the second argument `pcharcode' from FT_UInt* to FT_UInt32*.
3829 (tt_cmap4_char_map_binary): Ditto.
3830 (tt_cmap14_get_nondef_chars): Change the type of return value

3853 the beginning of sfnt container.
3854 * src/sfnt/ttload.c (check_table_dir): Return
3855 `SFNT_Err_Table_Missing' when sfnt table directory structure is
3856 correct but essential tables for TrueType fonts (`head', `bhed' or
3857 `SING') are missing. Other errors are returned by
3858 SFNT_Err_Unknown_File_Format.
3860 * src/base/ftobjs.c (FT_Open_Face): When TrueType driver returns
3861 `FT_Err_Table_Missing', try `open_face_PS_from_sfnt_stream'. It is
3862 enabled only when old mac font support is configured.
3864 2008-10-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

3886 (ft_lookup_PS_in_sfnt_stream): This.
3887 (open_face_PS_from_sfnt_stream): New function. It checks whether
3888 the stream is sfnt-wrapped Type1 PS font or sfnt-wrapped CID-keyed
3889 font, then try to open a face for given face_index.
3890 (Mac_Read_sfnt_Resource): Replace the combination of
3891 `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' by

3900 * src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Set *is_sfnt_cid to
3901 FALSE if neither `CID ' nor `TYP1' is found in the sfnt container.
3903 2008-10-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3905 * include/freetype/config/ftconfig.h: Define FT_MACINTOSH when SC or
3906 MrC compiler of MPW is used. These compilers do not define the
3907 macro __APPLE__ by themselves.
3908 * builds/unix/ftconfig.in: Ditto.
3909 * builds/vms/ftconfig.h: Ditto.
3910 * src/base/ftbase.c: Use FT_MACINTOSH instead of __APPLE__, to
3911 include ftmac.c if FreeType 2 is built by MPW.
3912 * src/base/ftobjs.c: Use FT_MACINTOSH instead of __APPLE__, to
3913 enable shared functions for ftmac.c if FreeType 2 is built by MPW.

3923 included part of ftbase.c, to share the functions in ftobjs.c. The
3924 rule compiling ftmac.c separately is removed and the rule copying
3925 ftbase.c from src/base/ftbase.c to builds/mac/ftbase.c is added.
3926 * builds/mac/FreeType.m68k_cfm.make.txt: Ditto.
3927 * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
3928 * builds/mac/FreeType.ppc_carbon.make.txt: Ditto.

3949 * src/base/ftbase.h: New file to declare the private utility
3950 functions shared by the sources of base modules. Currently,
3951 `ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
3952 share between ftobjs.c and ftmac.c.
3954 * src/base/rule.mk: Add ftbase.h.
3956 * src/base/ftobjs.c: Include ftbase.h.
3957 (memory_stream_close): Build on any platform when old MacOS font
3959 (new_memory_stream): Ditto.
3960 (open_face_from_buffer): Build on any platform when old MacOS font
3961 support is enabled. The counting of the face in a font file is
3962 slightly different between Carbon-dependent parser and Carbon-free
3963 parser. They are merged with the platform-specific conditional.
3964 (ft_lookup_PS_in_sfnt): Ditto.
3966 * src/base/ftmac.c: Include ftbase.h.
3967 (memory_stream_close): Removed.

3975 * src/sfnt/sfobjs.c (sfnt_load_face): `psnames_error' is only needed
3976 if TT_CONFIG_OPTION_POSTSCRIPT_NAMES is defined.
3978 2008-10-01 Werner Lemberg <wl@gnu.org>
3980 * src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c
3981 (cff_face_done), src/pfr/pfrobjs.c (pfr_face_done),
3982 src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c
3983 (cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done),
3984 src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0.
3985 Reported by Graham Asher.
3987 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3989 * src/base/rules.mk: Add conditional source to BASE_SRC, for `make
3990 multi' on Mac OS X. If the macro $(ftmac_c) is defined,
3991 $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the
3992 lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
3994 * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
3995 * builds/unix/configure.raw: Add procedure to set up appropriate
3996 value of $(ftmac_c) with the consideration of the availability of
3999 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4001 * src/base/Jamfile: Add target for multi build by jam on Mac OS X.
4002 * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this
4003 function for MPW building. It is synchronized the condition to
4004 include ftmac.c source into ftbase.c.
4006 2008-09-22 Werner Lemberg <wl@gnu.org>
4008 * src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
4009 cff_decoder_parse_charstrings): Handle (invalid)
4010 `callothersubr' and `pop' instructions.
4012 2008-09-22 John Tytgat <John.Tytgat@esko.com>
4014 Fix Savannah bug #24307.
4016 * include/freetype/internal/t1types.h (CID_FaceRec),
4017 src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.
4019 2008-09-21 Werner Lemberg <wl@gnu.org>
4021 * src/smooth/ftgrays.c (gray_raster_render): Don't dereference
4022 `target_map' if FT_RASTER_FLAG_DIRECT is set. Problem reported by
4023 Stephan T. Lavavej <stl@nuwen.net>.
4025 2008-09-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4027 * src/otvalid/Jamfile: Add missing target `otvmath' for multi build
4029 * src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
4032 2008-09-20 Werner Lemberg <wl@gnu.org>
4034 * src/smooth/ftgrays.c (gray_find_cell): Fix threshold. The values
4035 passed to this function are already `normalized'. Problem reported
4036 by Stephan T. Lavavej <stl@nuwen.net>.
4038 * docs/CHANGES: Document it.
4040 2008-09-20 Werner Lemberg <wl@gnu.org>
4042 * src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
4043 (FT_Outline_Decompose): Decorate with tracing messages.
4045 * src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
4046 FT_DEBUG_LEVEL_TRACE.
4047 [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
4050 (FT_TRACE) [_STANDALONE_]: Remove.
4051 (FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
4052 (FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.

4074 2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4076 * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
4077 sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
4078 `open_face_from_buffer' frees the passed buffer if it cannot open a
4079 face from the buffer, so the caller must not free it.
4081 2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4083 * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
4084 for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
4085 (ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '

4090 Type1 and sfnt-wrapped CID-keyed font support.
4092 2008-09-18 Werner Lemberg <wl@gnu.org>
4094 * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
4095 orthogonality (ft_free and ft_sfree could belong to different memory
4096 pools). This fixes Savannah bug #24297.
4098 2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4100 * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
4101 in ttags.h instead of numerical value 0x4F54544FL.
4103 2008-09-16 Werner Lemberg <wl@gnu.org>
4105 * src/cff/cffgload.h, src/cff/cffgload.c

4110 Fix Savannah bug #24179, reported by Bram Tassyns.
4112 * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
4115 2008-09-15 Werner Lemberg <wl@gnu.org>
4117 * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
4118 and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
4119 prevent unconditional definition. This fixes Savannah bug #24241.
4121 * src/psnames/pstables.h: Regenerated.
4123 2008-09-13 Werner Lemberg <wl@gnu.org>
4125 * autogen.sh, builds/unix/configure.raw,
4126 include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
4129 * include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
4130 include/freetype/ftlcdfil.h: Protect against FreeType 1.
4131 Some other minor fixes.
4133 * devel/ftoption.h: Synchronize with
4134 include/freetype/config/ftoption.h.
4136 2008-09-11 Werner Lemberg <wl@gnu.org>
4138 * src/base/ftbase.c: Include ftadvanc.c.
4140 2008-09-11 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

4143 FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
4144 (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp
4145 computation is disabled and the statically configured sizes are
4146 used. This fixes Savannah bug #21250.
4148 * builds/unix/configure.raw: Add the checks to compare the cpp
4149 computation results of the bit length of int and long versus the
4150 sizes detected by running `configure'. If the results are
4151 different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
4153 New option --{enable|disable}-biarch-config is added to define or
4154 undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
4156 2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4158 * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
4159 ApplicationService framework is missing. Although this value is not
4160 used in building of FreeType2, it is written in `freetype2.pc' and
4163 2008-09-01 david turner <david@freetype.org>
4165 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
4166 index to mean `use default cached FT_Face's charmap'. This fixes
4167 Savannah bug #22625.
4168 * include/freetype/ftcache.h: Document it.
4171 Make FT_MulFix an inlined function. This is done to speed up
4172 FreeType a little (on x86 3% when loading+hinting, 10% when
4173 rendering, ARM savings are more important though). Disable this by
4174 undefining FT_CONFIG_OPTION_INLINE_MULFIX.
4176 Use of assembler code can now be controlled with
4177 FT_CONFIG_OPTION_NO_ASSEMBLER.
4179 * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
4180 [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler

4190 * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
4191 FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
4193 * include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
4195 * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
4199 Add a new header named FT_ADVANCES_H declaring some new APIs to
4200 extract the advances of one or more glyphs without necessarily
4201 loading their outlines. Also provide `fast loaders' for the
4202 TrueType, Type1, and CFF font drivers (more to come later).
4204 * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
4206 * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.

4216 * src/cff/cffdrivr.c (cff_get_advances): New function.
4217 (cff_driver_class): Register it.
4219 * src/cff/cffgload.c (cff_decoder_set_width_only): New function.
4220 (cff_decoder_parse_charstrings): Handle `width_only'.
4221 (cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.
4223 * src/cff/cffgload.h (cff_decoder): New element `width_only'.
4224 (cff_decoder_set_width_only): New declaration.
4226 * src/truetype/ttdriver.c (tt_get_advances): New function.
4227 (tt_driver_class): Register it.
4229 * src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
4230 (TT_Get_HMetrics, TT_Get_VMetrics): This.
4232 * src/truetype/ttgload.h: Declare them.
4234 * src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
4236 * src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.
4239 Add checks for minimum version of the `autotools' stuff.
4241 * autogen.sh: Implement it.
4242 (get_major_version, get_minor_version, get_patch_version,
4243 compare_to_minimum_version, check_tool_version): New auxiliary
4246 * README.CVS: Document it.

4250 * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
4251 ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).
4253 2008-08-28 Werner Lemberg <wl@gnu.org>
4255 * src/type1/t1load.c (parse_encoding): Protect against infinite
4256 loop. This fixes Savannah bug #24150 (where a patch has been posted
4259 2008-08-23 Werner Lemberg <wl@gnu.org>
4261 * src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
4262 (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug
4265 2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4267 * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
4268 even if passed library or arguments are invalid. This fixes a bug
4269 that an uninitialized stream is freed when an invalid library handle
4270 is passed. Originally proposed by Mike Fabian, 2008/08/18 on
4272 (FT_Open_Face): Ditto (stream).
4273 (load_face_in_embedded_rfork): Ditto (stream2).
4275 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4277 * src/base/ftmac.c: Add a fallback to guess the availability of the
4278 `ResourceIndex' type. It is used when built without configure
4279 (e.g., a build with Jam).
4280 * builds/mac/ftmac.c: Ditto.
4281 * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
4282 explicitly, even if `ResourceIndex' is unavailable.
4284 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4286 * builds/unix/configure.raw: In checking of Mac OS X features,
4287 all-in-one header file `Carbon.h' is replaced by the minimum
4288 header file `CoreServices.h', similar to current src/base/ftmac.c.
4290 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4292 * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
4293 sub-header when its code_count is 0. Many Japanese Dynalab fonts
4294 include such an empty sub-header (code_count == 0, first_code == 0
4295 delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
4297 2008-08-04 Werner Lemberg <wl@gnu.org>
4299 * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
4300 Savannah bug #23995.
4302 * src/cid/cidload.c (parse_expansion_factor): New callback function.
4303 (cid_field_records): Use it for `ExpansionFactor'.
4304 * src/cod/cidtoken.h: Handle `ForceBold' keyword.
4305 Don't handle `ExpansionFactor'.
4307 2008-08-04 Bram Tassyns <bramt@enfocus.be>
4309 * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
4310 resulted in incorrect scaling. This fixes Savannah bug #23973.
4312 2008-08-04 Werner Lemberg <wl@gnu.org>
4314 Be more tolerant w.r.t. invalid entries in SFNT table directory.
4316 * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
4318 Add more trace messages.
4319 (tt_face_load_font_dir): Updated.
4321 2008-07-30 Werner Lemberg <wl@gnu.org>
4323 * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
4324 assume that the first argument on the stack is the bottom-most
4325 element. Two reasons:
4327 o According to people from Adobe it is missing in the Type 2
4328 specification that pushing of additional, superfluous arguments
4329 on the stack is prohibited.
4331 o Acroread in general handles fonts differently, namely by popping
4332 the number of arguments needed for a particular operand (as a PS
4333 interpreter would do). In case of buggy fonts this causes a
4334 different interpretation which of the elements on the stack are
4335 superfluous and which not.
4337 Since there are CFF subfonts (embedded in PDFs) which rely on
4338 Acroread's behaviour, FreeType now does the same.
4340 2008-07-27 Werner Lemberg <wl@gnu.org>
4342 Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
4343 fixes Savannah bug #23940.
4345 * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
4346 (EXTRA_GLYPH_LIST_SIZE): This.
4348 (ft_wgl_extra_unicodes): Rename to...
4349 (ft_extra_glyph_unicodes): This.
4350 Add two code values.
4351 (ft_wgl_extra_glyph_names): Rename to...
4352 (ft_extra_glyph_names): This.
4354 (ft_wgl_extra_glyph_name_offsets): Rename to...
4355 (ft_extra_glyph_name_offsets): This.
4358 (ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
4359 (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
4361 (ps_unicodes_init): Updated.
4363 2008-07-26 Werner Lemberg <wl@gnu.org>
4365 * src/cff/cffgload.c (cff_decoder_prepare,
4366 cff_decoder_parse_charstrings): Improve debug output.
4368 2008-07-22 Martin McBride <mmcbride@emtex.com>
4370 * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
4371 tt_cmap4_char_map_binary): Handle fonts which treat the last segment
4372 specially. According to the specification, such fonts would be
4373 invalid but acroread accepts them.
4375 2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk>
4377 * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
4379 * src/base/ftcalc.c (FT_MulFix): Fix portability issue.
4381 * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
4382 Fix compiler warning.
4384 2008-07-16 Werner Lemberg <wl@gnu.org>
4386 Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.
4388 * src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
4389 Invert sids table only if `pure_cff' is set.
4390 * src/cff/cffload.h: Udpated.
4392 * src/cff/cffobjs.c (cff_face_init): Updated.
4393 Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.
4395 * docs/CHANGES: Updated.
4397 2008-07-09 Werner Lemberg <wl@gnu.org>
4399 * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
4400 where num_locations < num_glyphs. Problem reported by Ding Li.
4402 2008-07-05 Werner Lemberg <wl@gnu.org>
4404 Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
4405 newer. This fixes Savannah bug #23648.
4407 * configure: zsh doesn't like ${1+"$@"}.
4408 Update needed GNU make version.
4409 * builds/toplevel.mk: Check for `$(eval ...)'.
4410 * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
4413 2008-07-04 Werner Lemberg <wl@gnu.org>
4415 * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
4416 pixel, only check for dropouts if neither start nor end point lies
4417 on a pixel center. This fixes Savannah bug #23762.
4419 2008-06-29 Werner Lemberg <wl@gnu.org>
4421 * Version 2.3.7 released.
4422 =========================
4425 Tag sources with `VER-2-3-7'.
4427 * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
4428 version number to 2.3.7.
4430 * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
4431 builds/win32/visualc/freetype.dsp,
4432 builds/win32/visualc/freetype.vcproj,
4433 builds/win32/visualce/index.html,
4434 builds/win32/visualce/freetype.dsp,
4435 builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
4437 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
4439 * builds/unix/configure.raw (version_info): Set to 9:18:3.
4441 * docs/release: Updated.
4443 2008-06-28 Werner Lemberg <wl@gnu.org>
4445 * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
4446 * src/ftcalc.c: Here. This fixes Savannah bug #23729.
4448 2008-06-27 Werner Lemberg <wl@gnu.org>
4450 * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
4451 Horizontal_Gray_Sweep_Drop): Test for intersections which
4452 degenerate to a single point can be ignored; this has been confirmed
4453 by Greg Hitchcock from Microsoft. (This was commented out code.)
4455 2008-06-26 Werner Lemberg <wl@gnu.org>
4457 Improve navigation in API reference.
4459 * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
4460 (html_header_6): This.
4461 (html_header_3, html_header_3i, html_header_4, html_header_5,
4462 html_header_5t): New strings.
4463 (toc_footer_start, toc_footer_end): New strings.
4464 (HtmlFormatter::html_header): Updated.
4465 (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
4467 (HtmlFormatter::index_enter): Use `html_index_header'.
4468 (HtmlFormatter::index_exit): Print `html_footer'.
4469 (HtmlFormatter::toc_enter): Use `html_toc_header'.
4470 (HtmlFormatter::toc_exit): Print proper footer.
4472 Convert ~ to non-breakable space.
4474 * src/tools/docmaker/tohtml.py (make_html_para): Implement it.
4475 Update header files accordingly.
4477 2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4479 * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
4480 and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
4481 bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
4482 ResourceIndex type definition. The macro does not inform the type
4484 * src/base/ftmac.c: More parentheses are inserted to clarify the
4485 conditionals to disable legacy APIs in `10.5 and later' cases. If
4486 HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
4488 2008-06-24 Werner Lemberg <wl@gnu.org>
4490 * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
4493 * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
4494 Draw_Sweep): No-dropout mode is value 2, not value 0.
4495 (Draw_Sweep): Really skip dropout handling for no-dropout mode.
4497 2008-06-24 Werner Lemberg <wl@gnu.org>
4499 * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
4500 if it consists of one point only. Based on a patch from Savannah
4501 bug #23683 (from John Tytgat).
4503 2008-06-22 Werner Lemberg <wl@gnu.org>
4505 * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
4508 * docs/CHANGES: Updated.
4510 2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4512 * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
4513 but LDFLAGS does not, import it to LDFLAGS. The option is used to
4514 specify non-default SDK on Mac OS X (e.g., universal binary SDK for
4515 Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
4516 recommends to add the option only to CFLAGS, LDFLAGS should include
4517 it because libfreetype.la is built with -no-undefined. This fixes a
4518 bug reported by Ryan Schmidt in MacPorts,
4519 http://trac.macports.org/ticket/15331.
4521 2008-06-21 Werner Lemberg <wl@gnu.org>
4523 Enable access to the various dropout rules of the B&W rasterizer.
4524 Pass dropout rules from the TT bytecode interpreter to the
4527 * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
4528 FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
4530 * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
4531 Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
4532 OpenType specification.
4533 Fix mode 4 computation.
4534 (Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
4536 * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
4537 mode to FT_OUTLINE_XXX flags.
4539 * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
4541 2008-06-19 Werner Lemberg <wl@gnu.org>
4543 * src/cff/cffobjs.c (cff_face_init): Compute final
4544 `dict->units_per_em' value before assigning it to
4545 `cffface->units_per_EM'. Otherwise, CFFs without subfonts are
4546 scaled incorrectly if the font matrix is non-standard. This fixes
4547 Savannah bug #23630.
4549 * docs/CHANGES: Updated.
4551 2008-06-19 Werner Lemberg <wl@gnu.org>
4553 * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
4556 2008-06-18 Werner Lemberg <wl@gnu.org>
4558 * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.
4559 Reported by Peter Weilbacher <mozilla@weilbacher.org>.
4561 * docs/CHANGES: Updated.
4563 2008-06-15 George Williams <gww@silcom.com>
4565 * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
4566 `valid->extra2' to 1. This is undocumented in the OpenType 1.5
4569 2008-06-15 Werner Lemberg <wl@gnu.org>
4571 * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
4572 from clobbering. Patch from Savannah bug report #23556.
4574 * docs/CHANGES: Document it.
4576 2008-06-10 Werner Lemberg <wl@gnu.org>
4578 * autogen.sh: Add option `--install' to libtoolize.
4580 2008-06-10 Werner Lemberg <wl@gnu.org>
4582 * Version 2.3.6 released.
4583 =========================
4586 Tag sources with `VER-2-3-6'.
4588 * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
4589 version number to 2.3.6.
4591 * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
4592 builds/win32/visualc/freetype.dsp,
4593 builds/win32/visualc/freetype.vcproj,

4596 builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/.
4598 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6.
4600 * builds/unix/configure.raw (version_info): Set to 9:17:3.
4603 * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x'
4605 * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'.
4608 * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H.
4609 * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
4611 2008-06-10 Werner Lemberg <wl@gnu.org>
4613 * src/base/ftobjs.c (open_face): Check `clazz->init_face' and
4616 2008-06-09 VaDiM <s_sliva@rambler.ru>
4618 Support debugging on WinCE. From Savannah patch #6536; this fixes
4621 * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
4622 as a replacement for OutputDebugStringA (which WinCE doesn't have).
4624 (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
4625 environment variables.
4627 2008-06-09 Werner Lemberg <wl@gnu.org>
4629 * README.CVS: Updated.
4631 * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
4632 for newer versions of autoconf and friends.
4634 2008-06-08 Werner Lemberg <wl@gnu.org>
4636 * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
4637 `private_len' unsigned.
4639 * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
4641 (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
4644 * src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
4647 * src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
4652 * src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
4655 * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
4659 * src/sfnt/ttload.c (tt_face_load_max_profile): Limit
4660 `maxTwilightPoints'.
4662 2008-06-06 Werner Lemberg <wl@gnu.org>
4664 * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
4665 correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
4667 2008-06-03 Werner Lemberg <wl@gnu.org>
4669 * include/freetype/ftcache.h (FTC_FaceID): Change type back to
4670 FT_Pointer. Reported by Ian Britten <britten@caris.com>.
4672 2008-06-02 Werner Lemberg <wl@gnu.org>
4674 Emit header info for defined FreeType objects in reference.
4676 * src/tools/docmaker/content.py (re_header_macro): New regexp.
4677 (ContentProcessor::__init__): Initialize new dictionary `headers'.
4678 (DocBlock::__init__): Collect macro header definitions.
4680 * src/tools/docmaker/tohtml.py (header_location_header,
4681 header_location_footer): New strings.
4682 (HtmlFormatter::__init__): Pass `headers' dictionary.
4683 (HtmlFormatter::print_html_field): Don't emit paragraph tags.
4684 (HtmlFormatter::print_html_field_list): Emit empty paragraph.
4685 (HtmlFormatter::block_enter): Emit header info.
4687 2008-06-01 Werner Lemberg <wl@gnu.org>
4689 * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
4690 FT_INCREMENTAL_H): Added.
4692 2008-05-28 Werner Lemberg <wl@gnu.org>
4694 * src/tools/docmaker/sources.py (SourceBlock::__init__): While
4695 looking for markup tags, return immediately as soon a single one is
4698 2008-05-28 Werner Lemberg <wl@gnu.org>
4700 * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
4701 original, unscaled input values. Confirmed by Greg Hitchcock from
4704 2008-05-27 Werner Lemberg <wl@gnu.org>
4706 * src/tools/docmaker/tohtml.py (block_footer_start,
4707 block_footer_middle): Beautify output.
4709 2008-05-25 Werner Lemberg <wl@gnu.org>
4711 * src/raster/ftraster.c (fc_black_render): Return 0 when we are
4712 trying to render into a zero-width/height bitmap, not an error code.
4714 * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
4715 of the graphics state for subglyphs to...
4716 (TT_Hint_Glyph): This function.
4717 Hinting instructions for a composite glyph apparently refer to the
4718 just hinted subglyphs, not the unhinted, unscaled outline. This
4719 seems to fix Savannah bugs #20973 and (at least partially) #23310.
4721 2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4723 * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
4724 `aface' is returned by FT_New_Face_From_FOND(). The patch was
4725 proposed by an anonymous reporter of Savannah bug #23204.
4727 2008-05-18 Werner Lemberg <wl@gnu.org>
4729 * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
4730 correction for pixel boundary. Without this patch, the effect can
4731 be cumulative under certain circumstances, making glyphs taller and
4732 taller after each call. This fixes Savannah bug #19976.
4734 2008-05-18 Werner Lemberg <wl@gnu.org>
4736 * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
4737 This fixes Savannah bug #23280.
4739 * docs/CHANGES: Updated.
4741 2008-05-18 David Turner <david@freetype.org>
4743 * src/psnames/psmodule.c (ft_wgl_extra_unicodes,
4744 ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
4745 ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
4746 declarations non-global.
4748 * src/type1/t1load.c: Add missing comment.
4750 2008-05-17 Sam Hocevar <samh>
4752 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
4753 glyphs correctly. Patch from Savannah bug #23277.
4755 2008-05-16 Werner Lemberg <wl@gnu.org>
4757 * docs/CHANGES: Updated.
4759 2008-05-16 Sergey Tolstov <stolstov@esri.com>
4761 Improve support for WGL4 encoded fonts.
4763 * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
4764 (ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,
4765 ft_wgl_extra_glyph_name_offsets): New arrays.
4766 (ps_check_wgl_name, ps_check_wgl_unicode): New functions.
4767 (ps_unicodes_init): Use them to add additional Unicode mappings.
4769 2008-05-15 Werner Lemberg <wl@gnu.org>
4771 * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
4772 <op_closepath>: `closepath' without a path is a no-op, not an error
4773 (cf. the PS reference manual).
4775 Reported by Martin McBride.
4777 2008-05-15 Werner Lemberg <wl@gnu.org>
4779 * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.
4781 2008-05-15 Werner Lemberg <wl@gnu.org>
4783 * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
4784 which contains a single but empty entry. This is technically
4785 invalid (since it must end with `return'), but...
4787 Reported by Martin McBride.
4789 2008-05-14 Werner Lemberg <wl@gnu.org>
4791 Finish fix of scaling bug of CID-keyed CFF subfonts.
4793 * include/freetype/internal/ftcalc.h, src/base/ftcalc.c
4794 (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
4797 * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
4798 provide global hinting data for both the top-font and all subfonts
4799 (with proper scaling).
4801 * src/cff/cffobjs.c (cff_make_private_dict): New function, using
4802 code from `cff_size_init'.
4803 (cff_size_init, cff_size_done, cff_size_select, cff_size_request):
4804 Use CFF_Internal and handle subfonts.
4805 (cff_face_init): Handle top-dict and subfont matrices correctly;
4806 apply some heuristic in case of unlikely matrix concatenation
4807 results. This has been discussed with people from Adobe (thanks
4808 goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
4811 * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
4813 * src/cff/cffgload.c (cff_builder_init): Updated.
4814 (cff_decoder_prepare): Handle hints globals for subfonts.
4816 (cff_slot_load): Handling scaling of subfonts properly.
4818 * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
4819 (cff_parse_font_matrix): Use it.
4821 * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
4824 * docs/CHANGES: Document it.
4826 2008-05-13 Werner Lemberg <wl@gnu.org>
4828 * src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
4829 Handle case `face_index < 0'.
4830 * docs/CHANGES: Document it.
4832 2008-05-04 Werner Lemberg <wl@gnu.org>
4834 First steps to fix the scaling bug of CID-keyed CFF subfonts,
4835 reported by Ding Li on 2008/03/28 on freetype-devel.
4837 * src/base/cff/cffparse.c (power_tens): New array.
4838 (cff_parse_real): Rewritten to introduce a fourth parameter which
4839 returns the `scaling' of the real number so that we have no
4840 precision loss. This is not used yet.
4842 (cff_parse_fixed_thousand): Replace with...
4843 (cff_parse_fixed_scaled): This function. Update all callers.
4845 2008-05-03 Werner Lemberg <wl@gnu.org>
4847 * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
4848 transformation since it recursively calls FT_Load_Glyph. This fixes
4849 Savannah bug #23143.
4851 2008-04-26 Werner Lemberg <wl@gnu.org>
4853 * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'
4854 and `scale_y' as obsolete since they aren't used.
4855 * src/psaux/psobjs.c (t1_builder_init): Updated.
4857 * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as
4858 obsolete since they aren't used.
4859 * src/cff/cffgload.c (cff_builder_init): Updated.
4861 2008-04-14 Werner Lemberg <wl@gnu.org>
4863 * src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to
4864 `FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZ'. From Savannah
4867 2008-04-13 Werner Lemberg <wl@gnu.org>
4869 * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
4870 integer part is zero.
4872 2008-04-01 Werner Lemberg <wl@gnu.org>
4874 Fix compilation with g++ 4.1 (with both `single' and `multi'
4877 * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
4878 which is crossed by a `goto'.
4880 * src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
4882 2008-03-31 Werner Lemberg <wl@gnu.org>
4884 Fix support for subsetted CID-keyed CFFs.
4886 * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
4887 FT_IS_CID_KEYED): New macros.
4889 * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
4890 maximum CID value in CID-keyed CFFs.
4891 Handle FT_FACE_FLAG_CID_KEYED flag.
4893 * docs/CHANGES: Document it.
4896 Fix CFF font matrix calculation and improve precision.
4898 * src/cff/cffparse.c (cff_parse_real): Increase precision if integer
4900 (cff_parse_font_matrix): Simplify computation of `units_per_em';
4901 this prevents overflow also.
4904 Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
4906 * src/cid/cidriver.c: Include FT_SERVICE_CID_H.
4907 (cid_get_ros): New function.
4908 (cid_service_cid_info): New service structure.
4909 (cid_services): Register it.
4911 2008-03-23 Werner Lemberg <wl@gnu.org>
4913 Adjustments for Visual C++ 8.0, as reported by Rainer Deyke.
4915 * builds/compiler/visualc.mk (CFLAGS): Remove /W5.
4916 (ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
4918 2008-03-21 Laurence Darby <ldarby>
4920 * src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from
4921 Savannah bug #22675.
4923 2008-03-13 Derek Clegg <dclegg@apple.com>
4925 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.
4926 Patch from Savannah bug #22541.
4928 2008-03-03 Masatoshi Kimura <VYV03354@nifty.ne.jp>
4930 * src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
4931 tt_cmap14_find_variant): Return correct value.
4932 (tt_cmap14_variant_chars): Fix check for `di'.
4934 2008-02-29 Wermer Lemberg <wl@gnu.org>
4936 * docs/CHANGES: Updated.
4940 Add build support for symbian platform. From Savannah bug #22440.
4942 * builds/symbian/*: New files.
4944 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4946 * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
4947 synthesis. For any face of a specified FOND, always the name for
4948 the first face was used. Except of a FOND that refers multiple
4949 Type1 font files, wrong synthesized font names are not used at all,
4950 so this is an invisible bug. A few limit checks are added too.
4952 * builds/mac/ftmac.c: Ditto.
4954 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4956 * builds/unix/configure.raw: Split compiler option to link Carbon
4957 frameworks to one option for CoreServices framework and another
4958 option for ApplicationServices framework. The split options can be
4959 managed by GNU libtool to avoid unrequired duplication when FreeType
4960 is linked with other applications. Suggested by Daniel Macks,
4961 Savannah bug #22366.
4963 2008-02-18 Victor Stinner <victor.stinner@haypocalc.com>
4965 * src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix
4966 from Savannah bug #22356.
4968 2008-02-17 Jonathan Blow <jon@number-none.com>
4970 * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
4971 Check for valid callback pointers.
4973 2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4975 * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
4976 handle by its value instead of ResError(), fix provided by Deron
4977 Kazmaier. According to the Resource Manager Reference,
4978 GetResource(), Get1Resource(), GetNamedResource(),
4979 Get1NamedResource() and RGetResource() set noErr but return NULL
4980 handle when they can not find the requested resource. These
4981 functions never return undefined values, so it is sufficient to
4982 check if the handle is not NULL.
4984 * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
4986 2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4988 * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
4989 inclusion styles. Now it always includes src/base/ftmac.c;
4990 builds/mac/ftmac.c is never included in any configuration.
4992 * builds/unix/configure.raw: Print warning if configure is executed
4993 with options to specify Carbon functionalities explicitly.
4995 * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
4996 included automatically and manual replacement is required.
4998 2008-02-11 Werner Lemberg <wl@gnu.org>
5000 * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
5001 (dos_setup), builds/freetype.mk (clean_project_dos,
5002 distclean_project_dos): Don't use \ but $(SEP). Reported by Duncan
5005 2008-01-18 Sylvain Pasche <sylvain.pasche@gmail.com>
5007 * src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to
5008 mention intra-pixel algorithm.
5010 * include/freetype/freetype.h (FT_Render_Mode): Mention that
5011 FT_Library_SetLcdFilter can be used to reduce fringes.
5013 2008-01-16 Werner Lemberg <wl@gnu.org>
5015 * src/raster/ftraster.c (ft_black_render): Check `outline' before
5016 using it. Reported by Allan Yang.
5018 2008-01-12 Werner Lemberg <wl@gnu.org>
5020 * src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove.
5022 2008-01-12 Allan Yang, Jian Hua - SH <Allan.Yang@fmc.fujitsu.com>
5024 * src/raster/ftraster.c (ft_black_init)
5025 [FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.
5027 2008-01-10 Werner Lemberg <wl@gnu.org>
5029 * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
5030 where the number of contours in a simple glyph is zero (and which
5031 does contain an entry in the `glyf' table). This fixes Savannah bug
5034 2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5036 Formatting suggested by Sean McBride.
5038 * builds/mac/ftmac.c: Formatting (tab expanded).
5039 * src/autofit/afindic.c: Ditto.
5040 * src/base/ftcid.c: Ditto.
5041 * src/base/ftmac.c: Ditto.
5043 2007-12-30 Werner Lemberg <wl@gnu.org>
5045 * src/smooth/ftgrays.c (gray_raster_render): Check `outline'
5048 2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5050 Improvement of POSIX resource-fork accessor to load unsorted
5051 references in a resource. In HelveLTMM (resource-fork PostScript
5052 Type1 font bundled with Mac OS X since 10.3.x), the appearance order
5053 of PFB chunks is not sorted; sorting the chunks by reference IDs is
5056 * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
5057 type to store a pair of reference ID and offset to the chunk.
5059 * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
5060 sort FT_RFork_Ref by their reference IDs.
5062 (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
5063 sorted by reference ID.
5065 2007-12-14 Werner Lemberg <wl@gnu.org>
5067 * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
5068 division too early; otherwise the most significant digit(s) of the
5069 final result are lost as the value is truncated to an integer. This
5070 fixes Savannah bug #21794 (where the patch has been posted too).
5072 2007-12-06 Fix <4d876b82@gmail.com>
5074 Pass options from one configure script to another as-is (not
5075 expanded). This is needed for options like
5076 --includedir='${prefix}/include'.
5078 * builds/unix/detect.mk, configure: Prevent argument expansion in
5079 call to the (real) `configure' script.
5081 2007-12-06 Werner Lemberg <wl@gnu.org>
5083 * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
5084 TT_USE_BYTECODE_INTERPRETER isn't defined.
5086 2007-12-06 Werner Lemberg <wl@gnu.org>
5088 There exist CFFs which contain opcodes for the Type 1 operators
5089 `hsbw' and `closepath' which are both invalid in Type 2 charstrings.
5090 However, it doesn't harm to support them.
5092 * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
5094 (cff_argument_counts): Ditto.
5096 (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
5097 and 13 (hsbw) which are invalid in Type 2 charstrings.
5099 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5101 * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
5102 support new pathname syntax `..namedfork/rsrc' to access a resource
5103 fork on Mac OS X. The legacy syntax `/rsrc' does not work on
5104 case-sensitive HFS+.
5105 (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
5106 buffer size to store a pathname.
5107 * include/freetype/internal/ftrfork.h: Increment the number of
5108 resource fork guessing rule.
5110 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5112 * builds/unix/configure.raw: Improve the compile tests to search
5114 * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
5115 proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).
5117 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5119 The documents and comments for Mac OS X are improved by Sean
5122 * src/base/ftmac.c: Fix a comment.
5123 * include/freetype/ftmac.h: Ditto.
5124 * docs/INSTALL.MAC: Improve English and add comment on lowest
5125 system version specified by MACOSX_DEPLOYMENT_TARGET.
5127 2007-12-04 Werner Lemberg <wl@gnu.org>
5129 * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to
5130 concatenate error codes.
5131 * src/sfnt/ttsbit.c (Load_SBit_Range): Ditto.
5133 2007-12-04 Graham Asher <graham.asher@btinternet.com>
5135 * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
5136 concatenate error codes.
5138 2007-12-04 Sean McBride <sean@rogue-research.com>
5140 * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler
5143 2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5145 Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
5146 not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
5147 cannot mmap() the specified file and cannot seek to head of the
5148 specified file, it returns NULL stream and FT_Open_New() returns the
5149 error immediately. On MacOS, most legacy MacOS fonts fall into such
5150 a scenario because their data forks are zero-sized and cannot be
5151 sought. To proceed to guessing of resource fork fonts, the
5152 functions for legacy MacOS font must properly handle the NULL stream
5153 returned by FT_New_Stream().
5155 * src/base/ftobjs.c (IsMacBinary): Return error
5156 FT_Err_Invalid_Stream_Operation immediately when NULL stream is
5158 (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
5159 to fallback. Originally, legacy MacOS font is tested in the cases
5160 of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
5161 or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
5162 .dfont header is combined). Now the case of
5163 FT_Err_Cannot_Open_Stream is included.
5165 * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
5166 skip FT_Stream_Seek(), which seeks to the head of stream, and
5167 proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
5168 for a NULL stream causes a Bus error on Mac OS X.
5169 (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
5170 immediately if passed stream is NULL.
5171 (raccess_guess_apple_single): Ditto.
5173 2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5175 Fix for Carbon incompatibilities since Mac OS X 10.5,
5176 proposed by Sean McBride.
5178 * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
5180 * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
5181 FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
5182 Carbon functions from a forked process is classified as unsafe
5183 by Apple. All Carbon-dependent functions should be deprecated.
5185 * src/base/ftmac.c: Use essential header files
5186 <CoreServices/CoreServices.h> and
5187 <ApplicationServices/ApplicationServices.h> instead of
5188 all-in-one header file <Carbon/Carbon.h>.
5190 Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
5191 genuine macro PATH_MAX.
5193 Add fallback macro for kATSOptionFlagsUnRestrictedScope which
5194 is not found in Mac OS X 10.0.
5196 Multi-character constants ('POST', 'sfnt' etc) are replaced by
5197 64bit constants calculated by FT_MAKE_TAG() macro.
5199 For the index in the segment of resource fork, new portable
5200 type ResourceIndex is introduced for better compatibility.
5201 This type is since Mac OS X 10.5, so it is defined as short
5202 when built on older platforms.
5204 (FT_ATSFontGetFileReference): If build target is only the systems
5205 10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
5207 (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
5208 and newer or 64bit platform, because legacy type FSSpec type is
5211 (FT_New_Face_From_FSSpec): Ditto.
5213 2007-11-01 Werner Lemberg <wl@gnu.org>
5215 * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
5216 fixes Savannah bug #21485.
5218 2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
5220 * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
5221 can handle the font at all, then check `face_index'. Otherwise, the
5222 driver might return the wrong error code. This fixes Savannah bug
5225 2007-10-21 Werner Lemberg <wl@gnu.org>
5227 * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
5228 support for bit 8 of the `fsSelection' field in the `OS/2' table.
5229 MS is already using this; hopefully, this becomes part of OpenType
5231 Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
5234 2007-10-20 Werner Lemberg <wl@gnu.org>
5236 * src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
5237 Add `td.left' element to CSS.
5238 (toc_section_enter): Use it.
5240 2007-10-18 David Turner <david@freetype.org>
5242 * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
5243 functions related to cmap type 14 support to the
5244 `FT_Object_ActionName' scheme:
5246 FT_Get_Char_Variant_index -> FT_Face_GetCharVariantIndex
5247 FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
5248 FT_Get_Variant_Selectors -> FT_Face_GetVariantSelectors
5249 FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar
5250 FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant
5252 Update documentation accordingly.
5254 * src/sfnt/ttcmap.c: Stronger cmap 14 validation.
5255 Make the code a little more consistent with FreeType coding
5256 conventions and modify the cmap14 functions that returned a newly
5257 allocated array to use a persistent vector from the TT_CMap14 object
5260 (TT_CMap14Rec): Provide array and auxiliary data for result.
5261 (tt_cmap14_done, tt_cmap14_ensure): New functions.
5263 (tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary,
5264 tt_cmap14_char_map_nondef_binary, tt_cmap14_find_variant,
5265 tt_cmap14_char_var_index, tt_cmap14_variants,

5267 tt_cmap14_get_def_chars, tt_cmap14_get_nondef_chars,
5268 tt_cmap14_variant_chars, tt_cmap14_class_rec): Updated and improved.
5270 2007-10-15 George Williams <gww@silcom.com>
5272 Add support for cmap type 14.
5274 * devel/ftoption.h, include/freetype/config/ftoption.h
5275 (TT_CONFIG_CMAP_FORMAT_14): New macro.
5277 * include/freetype/internal/ftobjs.h (FT_CMap_CharVarIndexFunc,
5278 FT_CMap_CharVarIsDefaultFunc, FT_CMap_VariantListFunc,
5279 FT_CMap_CharVariantListFunc, FT_CMap_VariantCharListFunc): New
5280 support function prototypes.
5281 (FT_CMap_ClassRec): Add them.
5284 * include/freetype/ttnameid.h (TT_APPLE_ID_VARIANT_SELECTOR): New
5287 * include/freetype/freetype.h (FT_Get_Char_Variant_Index,
5288 FT_Get_Char_Variant_IsDefault, FT_Get_Variant_Selectors,
5289 FT_Get_Variants_Of_Char, FT_Get_Chars_Of_Variant): New API
5292 * src/base/ftobjs.c (find_variant_selector_charmap): New auxiliary
5294 (FT_Set_Charmap): Disallow cmaps of type 14.
5295 (FT_Get_Char_Variant_Index, FT_Get_Char_Variant_IsDefault,
5296 FT_Get_Variant_Selectors, FT_Get_Variants_Of_Char,
5297 FT_Get_Chars_Of_Variant): New API functions.

6391 FT_GetFile_From_Mac_Name, FT_GetFile_From_Mac_ATS_Name are
6392 for passing to FT_New_Face_From_FSSpec.
6394 2007-02-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

6420 * Version 2.3.1 released.
6421 =========================
6424 Tag sources with `VER-2-3-1-FINAL'.
6426 * builds/win32/visualc/freetype.dsp,
6427 builds/win32/visualc/freetype.vcproj: s/230/231/.
6428 * builds/win32/visualc/index.html: s/221/231/.
6430 * vms_make.com: Add `ftgasp'.
6432 2007-01-30 David Turner <david@freetype.org>
6434 Tag sources with VER-2-3-1 to prepare release.
6436 * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
6438 * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
6441 * builds/unix/configure.raw (version_info): Set to 9:12:3.
6444 * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
6445 (af_loader_load_g): Disable the warper (i.e., the light hinting
6446 improvements) to make a 2.3.1 bugfix release before introducing a
6447 new feature. This should give us more time to tune and improve the
6448 warper for the next release.
6450 * docs/CHANGES: Update accordingly.
6452 2007-01-25 David Turner <david@freetype.org>
6454 For light auto-hinting, improve glyph advance widths and resurrect
6455 normal/full hinting to its normal quality.
6457 * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
6459 * src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
6462 * src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
6463 preprocessor conditional with if-clause, handling both light and
6466 * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
6467 (af_warper_compute): Handle `xmin_delta' and `xmax_delta'.
6469 2007-01-25 Werner Lemberg <wl@gnu.org>
6471 * docs/release: Updated -- Savannah uses a new uploading scheme.
6473 2007-01-25 David Turner <david@freetype.org>

6483 2007-01-25 Werner Lemberg <wl@gnu.org>
6485 * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
6486 correctly in a sanity check. Since this function is only used to
6487 load local and global functions, any charstring that called the last
6488 local/global function would fail otherwise. This fixes Savannah bug
6491 * docs/CHANGES: Document it.
6493 2007-01-23 David Turner <david@freetype.org>
6495 * src/truetype/ttobjs.c (tt_size_ready_bytecode): Fix typo that
6496 prevented compilation when disabling both the unpatented and the
6497 bytecode interpreter in the TrueType font driver.
6500 Fix and enable the warper to improve `light' hinting mode. This is
6501 not necessarily a final version, but it seems to work well.
6503 * src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
6505 (af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
6506 * src/autofit/aftypes.h: Activate AF_USE_WARPER.
6508 * src/autofit/afwarp.c (AF_WarpScore): Tune table.
6509 (af_warper_compute_line_best): Fix array size of `scores'.

6511 * src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
6514 2007-01-21 Werner Lemberg <wl@gnu.org>
6516 * ChangeLog: Split off older entries into...
6517 * ChangeLog.22: This new file.
6519 2007-01-21 Werner Lemberg <wl@gnu.org>
6521 * docs/CHANGES: Document SHZ fix.
6523 2007-01-21 George Williams <gww@silcom.com>
6525 * src/truetype/ttinterp.c (Ins_SHZ): SHZ doesn't move phantom
6528 2007-01-21 Werner Lemberg <wl@gnu.org>
6530 * src/sfnt/ttmtx.c (tt_face_get_metrics)
6531 [!FT_CONFIG_OPTION_OLD_INTERNALS]: Fix limit check.
6533 2007-01-17 Werner Lemberg <wl@gnu.org>

6550 (tt_face_init), src/truetype/ttinterp.c (Ins_SHC): Fix compiler
6553 2007-01-15 Detlef Würkner <TetiSoft@apg.lahn.de>
6555 * builds/amiga/makefile, builds/amiga/makefile.os4,
6556 builds/amiga/smakefile: Add `ftgasp.c' and `ftlcdfil.c'.
6558 * builds/amiga/include/freetype/config/ftconfig.h: Synchronize.
6560 2007-01-14 Detlef Würkner <TetiSoft@apg.lahn.de>
6562 Fix various compiler warnings.
6564 * src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h,
6565 src/cff/cffobjs.c (cff_size_request), src/type42/t42objs.h:
6566 s/index/strike_index/.

6569 * src/gxvalid/gxvmorx5.c
6570 (gxv_morx_subtable_type5_InsertList_validate): s/index/table_index/.
6572 * src/truetype/ttinterp.c (Compute_Point_Displacement),
6573 src/pcf/pcfread.c (pcf_seek_to_table_type): Avoid possibly
6574 uninitialized variables.
6576 2007-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
6578 * docs/CHANGES, docs/INSTALL.MAC: Improvements.
6580 2007-01-13 Werner Lemberg <wl@gnu.org>
6582 * src/type1/t1afm.c (T1_Read_Metrics): MS Windows allows PFM
6583 versions up to 0x3FF without complaining.
6585 2007-01-13 Derek Clegg <dclegg@apple.com>
6587 Add FT_Get_PS_Font_Info interface to CFF driver.

6603 * src/autofit/afhints.c (af_glyph_hints_dump_segments,
6604 af_glyph_hints_dump_edges): Ditto.
6606 * src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in
6609 * src/sfnt/ttsbit0.h: Remove.

6613 2007-01-12 David Turner <david@freetype.org>
6615 * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
6616 bug in the bitmap emboldener if the pitch of the source bitmap is
6617 much larger than its width.
6619 * src/truetype/ttinterp.c (Update_Max): Fix aliasing-related
6620 compilation warning.
6622 2007-01-12 Werner Lemberg <wl@gnu.org>
6624 * builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
6625 `automake' CVS module from sources.redhat.com.

6636 2007-01-11 David Turner <david@freetype.org>
6638 * docs/CHANGES: Small update.
6640 * builds/unix/configure.raw (version_info): Set to 9:11:3.
6642 * src/base/ftobjs.c (IsMacResource): Fix a small bug that caused a
6643 crash with some Mac OS X .dfont files. Submitted by Masatake
6646 * autogen.sh: Small fix to get it working on Mac OS X properly:
6647 The issue is that GNU libtool is called `glibtool' on this platform,
6648 and we must call `glibtoolize', since `libtoolize' doesn't exist.
6650 2007-01-10 David Turner <david@freetype.org>
6652 * all-sources: Tag all sources with VER-2-3-0-RC1 and
6655 * Jamfile (RefDoc), README, builds/win32/visualc/freetype.dsp,

6680 corresponding to a given character pixel size.
6682 * src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
6683 `gasp' table, in order to avoid potential problems with later
6686 * include/freetype/config/ftheader.h (FT_GASP_H): New macro for
6687 <freetype/ftgasp.h>.
6689 * src/base/rules.mk (BASE_SRC), src/base/Jamfile (_sources),
6690 modules.cfg (BASE_EXTENSIONS), builds/win32/visualc/freetype.dsp,
6691 builds/win32/visualc/freetype.vcproj: Add src/base/ftgasp.c to the
6694 2007-01-07 Werner Lemberg <wl@gnu.org>
6696 * src/cid/cidparse.c (cid_parser_new): Improve error message for
6698 Scan for `/sfnts' token.
6700 2007-01-07 Werner Lemberg <wl@gnu.org>
6702 * src/cid/cidparse.c (cid_parser_new): Reject Type 11 fonts.
6704 2007-01-06 Werner Lemberg <wl@gnu.org>
6706 * src/cff/cffload.c (cff_index_init): Remove unused variable.
6707 (cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.
6709 2007-01-04 David Turner <david@freetype.org>
6711 * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts

6716 going to load glyphs with the bytecode interpreter anyway.
6718 * src/truetype/ttgload.c (tt_loader_init): Load execution context
6719 only if glyph is hinted.
6721 * src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
6723 Add `tt_size_ready_bytecode' declaration.
6724 * src/truetype/ttobjs.c (tt_size_done_bytecode,
6725 tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
6726 (tt_size_init): Move most code into `tt_size_init_bytecode'.
6727 (tt_size_done): Move most code into `tt_size_done_bytecode'.
6728 (tt_size_reset): Move some code to `tt_size_ready_bytecode'.
6731 Don't extract the metrics table from the SFNT font file. Instead,
6732 reparse it on each glyph load. The runtime difference is not
6733 noticeable, and it can save a lot of heap memory when memory-mapped
6736 * include/freetype/internal/tttypes.h (TT_FaceRec): Add members
6737 `horz_metrics_offset' and `vert_metrics_ofset'.
6738 * src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
6742 * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
6745 Do not load the CFF index offsets into memory, since this wastes a
6746 *lot* of heap memory with large Asian CFF fonts. There is no
6747 significant performance loss.
6749 * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
6750 * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and

6756 (cff_new_index): Renamed to...
6757 (cff_index_init): This. Update all callers.
6758 Updated -- some code has been moved to `cff_index_load_offsets'.
6759 (cff_done_index): Renamed to...
6760 (cff_index_done): This. Update all callers.
6761 (cff_index_get_pointers, cff_index_access_element): Updated to use
6763 (cff_charset_compute_cids): Set `num_glyphs' field.
6764 (cff_encoding_load): Updated.
6766 * src/cff/cffgload.c (cff_slot_load): Updated.
6768 2007-01-04 David Turner <david@freetype.org>
6770 * docs/INSTALL.UNIX: Simplify some parts, add reference to
6771 autogen.sh and pointer to README.CVS.
6773 * README.CVS: Add common problem description and solution
6774 when running autogen.sh.

6780 * docs/TODO: Remove obsolete items.
6782 * src/raster/ftraster.c: (TRaster_Instance): Replace it with...
6784 Remove `count_table' and `memory'.
6785 Make `grays' a pointer.
6786 (TRaster): New structure.
6787 (count_table): New static array.
6788 (RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
6789 Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
6790 ft_black_set_mode, ft_black_render): Updated.
6791 (ft_black_init): Don't initialize `count_table'.
6792 (ft_black_reset): Use the render pool. This saves about 6KB of
6793 heap space for each FT_Library instance.
6795 * src/smooth/ftgrays.c (TRaster): Replaced with...
6798 (TRaster): New structure.
6800 (RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
6801 gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
6802 gray_render_span, gray_raster_render): Updated.
6803 (gray_raster_reset): Use the render pool. This saves about 6KB of
6804 heap space for each FT_Library instance.
6806 * src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
6807 src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
6808 src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
6809 FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
6810 the optimization is no longer experimental.
6812 * src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
6813 Remove a typo that results in no hinting and a memory leak with some
6814 large Asian CFF fonts.
6816 * src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
6817 which happens when FT_Done_Library is called with still opened
6818 CFF_Faces in it. We need to close all faces before destroying the
6819 modules, or else some bad things (memory leaks) may happen.
6821 2007-01-02 Werner Lemberg <wl@gnu.org>
6823 * src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
6824 Remove compiler warning.
6826 2007-01-02 David Turner <david@freetype.org>

6834 Check uniqueness of the gid pairs.
6835 (gxv_kern_subtable_fmt0_validate): Move some code to
6836 `gxv_kern_subtable_fmt0_pairs_validate'.
6838 2006-12-22 David Turner <david@freetype.org>
6840 * src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
6843 * builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
6844 to avoid deprecation warnings with Visual C++ 8.

6849 [FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.
6851 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
6853 * include/freetype/internal/services/svotval.h: Add `volatile' to
6854 sync with the modification by Jens Claudius on 2006-08-22; cf.
6855 http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5
6857 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

6860 * builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
6861 * builds/unix/configure.raw: Ditto. When explicit switches for
6862 FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
6863 builds/mac/ftmac.c is used instead of default src/base/ftmac.c.
6865 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
6867 * builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.
6868 * builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c
6869 instead of src/base/ftmac.c
6870 * builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
6871 * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
6872 * builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
6873 that cannot be built at present.
6875 2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
6877 * src/base/ftobjs.c: Improvement of resource fork handler for
6879 http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
6880 (Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
6881 format or .dfont, to simulate the face index number counted by ftmac.c.
6882 (IsMacResource): Return the number of scalable faces correctly.
6884 2006-12-10 Werner Lemberg <wl@gnu.org>
6886 * builds/toplevel.mk (version): Protect against `distclean' target.

6901 2006-12-08 Vladimir Volovich <vvv@vsu.ru>
6903 * src/tools/apinames.c (State): Remove final comma in structure --
6904 xlc v5 under AIX 4.3 doesn't like this.
6906 2006-12-07 David Turner <david@freetype.org>
6908 * src/autofit/afloader.c (af_loader_load_g): Small adjustment
6909 to the spacing of auto-fitted glyphs. This only impacts rare
6910 cases (e.g., Arial Bold at rather small character sizes).
6912 2006-12-03 Werner Lemberg <wl@gnu.org>
6914 * src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.
6916 2006-12-01 Werner Lemberg <wl@gnu.org>
6918 * src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are

6934 * src/smooth/ftgrays.c (gray_raster_render): Return 0 when we are
6935 trying to render into a zero-width/height bitmap, not an error code.
6937 * src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.
6939 * src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType
6942 * src/autofit/afhints.c (af_glyph_hints_dump_segments): Remove unused
6945 2006-11-26 Pierre Hanser <hanser@club-internet.fr>

6949 2006-11-25 David Turner <david@freetype.org>
6951 * src/autofit/afhints.c (af_glyph_hints_dump_points,
6952 af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
6953 Add stubs to link the `ftgrid' test program when debugging is
6954 disabled in the auto-hinter.
6956 2006-11-23 David Turner <david@freetype.org>
6958 * src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,
6959 src/autofit/aftypes.h: Miscellaneous auto-hinter improvements.
6961 * src/autofit/afhints.c (af_glyph_hints_dump_segments) [AF_DEBUG]:
6962 Emit more sensible information.

6980 program after a change from mono to grayscaling (and vice versa).
6981 Use correct constant for comparison to get `exec->grayscale'.
6983 2006-11-18 Werner Lemberg <wl@gnu.org>
6985 Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
6986 test for a valid glyph index must be deferred to the font drivers.
6987 This patch fixes Savannah bug #18301.
6989 * src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
6990 * src/bdf/bdfdrivr.c (BDF_Glyph_Load), src/cff/cffgload.c
6991 (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph),
6992 src/pcf/pcfdrivr.c (PCF_Glyph_Load), src/pfr/pfrobjs.c
6993 (pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),

6997 2006-11-13 David Turner <david@freetype.org>
6999 * src/truetype/ttinterp.c (FIX_BYTECODE): Undefine. The interpreter
7000 `enhancements' are still too buggy for general use.
7002 * src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
7003 FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros
7004 when building the library to change the default LCD filter to be
7005 used. This is only useful for experimentation.
7007 * include/freetype/ftlcdfil.h: Update documentation.
7009 2006-11-10 David Turner <david@freetype.org>
7011 * src/smooth/ftsmooth.c: API change for the LCD
7012 filter. The FT_LcdFilter value is an enumeration describing which
7013 filter to apply, with new values FT_LCD_FILTER_LIGHT and
7014 FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
7015 algorithm which produces strong color fringes for everything
7016 except very-well hinted text).
7018 * include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
7019 second parameter to an enum type.
7021 * src/base/ftlcdfil.c (USE_LEGACY): Define.

7032 callback and update other fields.
7034 * src/smooth/ftsmooth.c (ft_smooth_render_generic)
7035 [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
7036 Other minor improvements.
7038 * src/autofit/aflatin.c: Various tiny improvements that drastically
7039 improve the handling of serif fonts and of LCD/LCD_V hinting modes.
7040 (af_latin_hints_compute_edges): Fix typo.
7041 (af_latin_compute_stem_width): Take better care of diagonal stems.
7043 2006-11-09 David Turner <david@freetype.org>
7045 * src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
7046 typo which created a variable-used-before-initialized bug.

7050 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
7053 2006-11-03 Werner Lemberg <wl@gnu.org>
7055 * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.
7057 2006-11-02 David Turner <david@freetype.org>
7059 Add a few tweaks to better handle serif fonts.
7060 Add more debugging messages.
7062 * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
7063 segments that are less than 1.5 pixels high. This gets rid of
7064 *many* corner cases with serifs.
7065 (af_latin_align_linked_edge): Add logging message.
7066 (af_latin_hint_edges): Use AF_HINTS_DO_BLUES.
7067 Add logging messages.
7068 Handle AF_EDGE_FLAG flag specially.
7070 * src/autofit/afmodule.c [AF_DEBUG]: Add _af_debug,
7071 _af_debug_disable_blue_hints, and _af_debug_hints variables.
7073 * src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
7074 Update external declarations.
7075 (af_corner_orientation, af_corner_is_flat): Replaced by...

7084 These functions. Update all callers.
7085 (FT_Add64) [!FT_LONG64]: Simplify.
7087 * src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
7088 (af_direction_compute): Add a missing FT_ABS call. This bug caused

7111 2006-10-23 Zhe Su <zsu@novell.com>
7113 * src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
7114 better deal with broken Asian fonts with strange glyphs, having
7115 self-intersections and other peculiarities. The used algorithm is
7116 based on the nonzero winding rule.
7118 2006-10-23 David Turner <david@freetype.org>
7120 Speed up the CFF font loader. With some large CFF fonts,
7121 FT_Open_Face is now more than three times faster.
7123 * src/cff/cffload.c (cff_get_offset): Removed.
7124 (cff_new_index): Inline functionality of `cff_get_offset'.
7125 (cff_charset_compute_cids, cff_charset_free_cids): New functions.
7126 (cff_charset_done): Call `cff_charset_free_cids'.
7127 (cff_charset_load): Call `cff_charset_compute_cids'.

7160 find suffix for native executable and pass it by EXEEXT_BUILD.
7161 Also suffix for target executable is passed by EXEEXT.
7163 * builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
7164 build `apinames' which runs on building system. They are set by
7165 CC_BUILD and EXEEXT_BUILD.
7167 * builds/exports.mk (APINAMES_EXE): Change the extension for
7168 apinames from the suffix for target (E) to that for building host

7246 Add a new API to support color filtering of subpixel glyph bitmaps.
7247 In a default build, the function `FT_Library_SetLcdFilter' returns
7248 `FT_Err_Unimplemented_Feature'; you need to #define
7249 FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
7250 real implementation.
7252 * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.
7254 * include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
7256 (FT_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: New members
7257 `lcd_filter_weights' and `lcd_filter'.

7268 pointing to <freetype/ftlcdfil.h>.
7270 * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
7271 vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.

7293 (FT_CONFIG_OPTION_SUBPIXEL_RENDERING): New macro to control whether
7294 we want to compile LCD-optimized rendering code (Ã la ClearType) or
7295 not. The macro *must* be disabled in default builds of the library
7298 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
7299 LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
7300 isn't defined at compile time. This only changes the content of the
7301 rendered glyph to match the one of normal gray-level rendering,
7302 hence clients should not need to be modified.
7304 * docs/CHANGES: Updated.
7306 2006-09-18 Garrick Meeker <garrick@digitalanarchy.com>
7308 * src/base/ftmac.c (FT_New_Face_From_FOND): Fall back to SFNT if
7309 LWFN fails and both are available.
7311 2006-09-11 David Turner <david@freetype.org>

7318 will be selected correctly, though.
7320 * src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting

7366 to recognize a few fonts that require the automatic unpatented
7369 * src/smooth/ftgrays.c: Optmize the performance of the anti-aliased
7370 rasterizer. The speed improvement is between 15% and 25%, depending
7373 (GRAYS_USE_GAMMA, GRAYS_COMPACT): Removed, and all associated code.
7375 (TRaster): New members `buffer', `buffer_size', `ycells', `ycount'.

7700 2006-06-25 Jens Claudius <jens.claudius@yahoo.com>
7702 The Type 1 parser now skips over top-level procedures as required
7703 for a `Simplified Parser'. This makes the parser more robust as it
7704 doesn't poke around in PostScript code. Additionally, it makes the
7705 FontDirectory hackery in src/type1/t1load.c unnecessary.
7707 * src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
7708 (skip_literal_string): Add FT_Error as return value.

7739 Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
7740 Mac. The original patch was written by David Sachitano and Lawrence
7741 Coopet, and modified by Sean McBride for MPW compatibility. Only
7742 required data are converted; unused data are left in big endian.
7744 * src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
7746 (OS_INLINE): Undefine before definition.
7747 (count_faces_sfnt): Insert EndianS16_BtoN to parse the header of
7748 FontAssociation table in FOND resource.

7756 (count_faces): Call `HUnlock' after all FOND utilization.
7758 2006-06-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
7760 Public API of TrueTypeGX, OpenType, and classic kern table validator
7761 should return `FT_Err_Unimplemented_Feature' if validation service
7762 is unavailable (disabled in `modules.cfg'). It is originally
7763 suggested by David Turner, cf.
7764 http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

7789 Fix memory leak described in Savannah bug #16759.
7791 We change `ps_unicodes_init' so that it also takes a
7792 `free_glyph_name' callback to release the glyph names returned by
7795 * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
7797 (PS_GetGlyphNameFunc): This.

7812 2006-06-04 David Turner <david@freetype.org>
7814 * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
7815 `item_size == 0' as well -- though this sounds weird, it can
7816 theoretically happen. This fixes Savannah bug #16669.
7818 * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
7819 of `face->num_glyphs' which missed the last glyph, due to
7820 the offset-by-1 computation, since the PFR format doesn't
7821 guarantee that glyph index 0 corresponds to the `missing
7822 glyph. This fixes Savannah bug #16668.
7824 2006-05-25 Werner Lemberg <wl@gnu.org>
7826 * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
7827 `-no-undefined'. Reported by Christian Biesinger.
7829 2006-05-19 Brian Weed <bw@imaginengine.com>
7831 * builds/win32/visualc/freetype.dsp: Release libraries no longer
7832 have debug information, and debug libraries use `C7 compatible'
7835 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
7837 Apply patch by Derek Clegg to fix two memory leaks in the MacOS

7860 [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
7862 2006-05-17 David Turner <david@freetype.org>
7864 This is a major patch used to drastically improve the performance of
7865 loading glyphs. This both speeds up loading the glyph vectors
7866 themselves and the auto-fitter module.
7868 We now use inline assembler code with GCC to implement `FT_MulFix',
7869 which is probably the most important function related to the
7870 engine's performance.
7872 The resulting speed-up is about 25%.
7875 * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
7876 `cursor' and `limit'.

7888 (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
7889 (af_glyph_hints_reload: Rewrite recognition of weak points.
7891 * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
7892 constant values out of the loops.
7894 * src/autofit/aftypes.h: Updated.
7896 * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

7899 product to get orientation.
7901 * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
7902 (FT_Stream_OpenGzip): Use it to handle small files directly in

7908 * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
7911 (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
7912 TT_Load_Composite_Glyph): Updated. Add threshold to protect against
7913 exceedingly large values of number of contours. Speed up by
7914 reducing the number of loops.
7916 * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
7919 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
7920 used to detect rogue clients from 4 to 16. This is to prevent some
7921 segmentation faults with fonts like `KozMinProVI-Regular.otf' which
7922 comes from the Japanese Adobe Reader Asian Font pack.
7924 2007-05-17 Werner Lemberg <wl@gnu.org>
7926 * src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
7927 fixes the first part of Savannah bug #16590.
7929 2006-05-16 Werner Lemberg <wl@gnu.org>
7931 * docs/PROBLEMS: Updated icl issues.
