FT_USE_MODULE declares things as:
extern const FT_Module_Class
(or similar for C++). However, the actual types of the variables
being declared are often different, e.g., FT_Driver_ClassRec or
FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
This works with most C compilers (since those structs begin with an
FT_Module_Class struct), but technically it's undefined behavior.
To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
paragraph 2:
All declarations that refer to the same object or function shall
have compatible type; otherwise, the behavior is undefined.
(And they are not compatible types.)
Most C compilers don't reject (or even detect!) code which has this
issue, but the GCC LTO development branch compiler does. (It
outputs the types of the objects while generating .o files, along
with a bunch of other information, then compares them when doing the
final link-time code generation pass.)
Patch from Savannah bug #25133.
* src/base/ftinit.c (FT_USE_MODULE): Include variable type.
* builds/amiga/include/freetype/config/ftmodule.h,
include/freetype/config/ftmodule.h, */module.mk: Updated to declare
pass correct types to FT_USE_MODULE.
2008-12-21 Hongbo Ni <hongbo@njstar.com>
* src/autofit/aflatin.c (af_latin_hint_edges),
src/autofit/aflatin2.c (af_latin2_hint_edges), src/autofit/afcjk.c
(af_cjk_hint_edges): Protect against division by zero. This fixes
Savannah bug #25124.
2008-12-18 Werner Lemberg <wl@gnu.org>
* docs/CHANGES: Updated.
2008-12-18 Bevan, David <dbevan@emtex.com>
Provide API for accessing embedding and subsetting restriction
information.
* include/freetype.h (FT_FSTYPE_INSTALLABLE_EMBEDDING,
FT_FSTYPE_RESTRICTED_LICENSE_EMBEDDING,
FT_FSTYPE_PREVIEW_AND_PRINT_EMBEDDING, FT_FSTYPE_EDITABLE_EMBEDDING,
FT_FSTYPE_NO_SUBSETTING, FT_FSTYPE_BITMAP_EMBEDDING_ONLY): New
macros.
(FT_Get_FSType_Flags): New function declaration.
* src/base/ftobjs.c (FT_Get_FSType_Flags): New function.
* src/cid/cidtoken.h, src/type1/t1tokens.h, src/type42/t42parse.c

2008-12-17 Werner Lemberg <wl@gnu.org>
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Don't use internal
macros so that copying the source code into an application works
out of the box.
2008-12-17 Werner Lemberg <wl@gnu.org>
* include/freetype/ftsynth.h, src/base/ftsynth.c: Move
FT_GlyphSlot_Own_Bitmap to...

* docs/CHANGES: Document it.
2008-12-10 Werner Lemberg <wl@gnu.org>
Generalize the concept of `tricky' fonts by introducing
FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
engine is necessary for correct rendering.
At the same time, slightly modify the behaviour of tricky fonts:
FT_LOAD_NO_HINTING is now ignored. To really force raw loading
of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
FT_LOAD_NO_AUTOHINT must be used.
Finally, tricky TrueType fonts always use the bytecode interpreter
even if the patented code is used.
* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
New macros.
* src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
semantics as described above.
* src/truetype/ttobjs.c (tt_check_trickyness): New function, using
code of ...
(tt_face_init): This function, now simplified and updated to new
semantics.
* src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
fonts.
* docs/CHANGES: Document it.
2008-12-09 Werner Lemberg <wl@gnu.org>
Really fix Savannah bug #25010: An SFNT font with neither outlines
nor bitmaps can be considered as containing space `glyphs' only.
* src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
a `glyf' table is missing.
* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
`glyf' table but a non-zero `loca' entry.
(tt_loader_init): Handle missing `glyf' table.
* src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.
* src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines
nor bitmaps is scalable.
2008-12-05 Werner Lemberg <wl@nu.org>
* src/autofit/aflatin.c (af_latin_uniranges): Add more ranges. This
fixes Savannah bug #21190 which also provides a basic patch.
2008-12-05 Werner Lemberg <wl@nu.org>
* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value
0x100 instead of 0x10000; the latter value is already occupied by
FT_LOAD_TARGET_LIGHT. Bug reported by James Cloos.
Handle SFNT with neither outlines nor bitmaps. This fixes Savannah
bug #25010.
* src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
outlines nor bitmaps.

is no table with glyphs.
* src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging
message.
2008-12-01 Werner Lemberg <wl@gnu.org>

2008-11-29 James Cloos <cloos@jhcloos.com>
* src/type/t1load.c (mm_axis_unmap): Revert previous patch and fix
it correctly by using FT_INT_TO_FIXED (FreeType expects 16.16 values
in the /BlendDesignMap space).
2008-11-29 James Cloos <cloos@jhcloos.com>
* src/type1/t1load.c (mm_axis_unmap): `blend_points' is FT_Fixed*,
whereas `design_points' is FT_Long*. Therefore, return blend rather
than design points.
2008-11-27 Werner Lemberg <wl@gnu.org>
* src/cff/cffparse.c (cff_parse_real): Handle more than nine
significant digits correctly. This fixes Savannah bug #24953.

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

Fix Savannah bug #24468.
According to include/freetype/internal/ftobjs.h, the appropriate
type to interchange single character codepoint is FT_UInt32. It
should be distinguished from FT_UInt which can be 16bit integer.
* src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Change the type
of the second argument `pcharcode' from FT_UInt* to FT_UInt32*.
(tt_cmap4_char_map_binary): Ditto.
(tt_cmap14_get_nondef_chars): Change the type of return value
from FT_UInt* to FT_UInt32*.
2008-10-08 John Tytgat <John.Tytgat@esko.com>

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

(ft_lookup_PS_in_sfnt_stream): This.
(open_face_PS_from_sfnt_stream): New function. It checks whether
the stream is sfnt-wrapped Type1 PS font or sfnt-wrapped CID-keyed
font, then try to open a face for given face_index.

`ft_lookup_PS_in_sfnt' and `open_face_from_buffer' by
`open_face_PS_from_sfnt_stream'.

* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
* src/base/ftbase.h: Remove `ft_lookup_PS_in_sfnt' and add
`open_face_PS_from_sfnt_stream'.
2008-10-03 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftobjs.c (ft_lookup_PS_in_sfnt): Set *is_sfnt_cid to
FALSE if neither `CID ' nor `TYP1' is found in the sfnt container.

2008-10-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftbase.h: New file to declare the private utility
functions shared by the sources of base modules. Currently,
`ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
share between ftobjs.c and ftmac.c.
* src/base/rule.mk: Add ftbase.h.
* src/base/ftobjs.c: Include ftbase.h.
(memory_stream_close): Build on any platform when old MacOS font
support is enabled.
(new_memory_stream): Ditto.
(open_face_from_buffer): Build on any platform when old MacOS font
support is enabled. The counting of the face in a font file is
slightly different between Carbon-dependent parser and Carbon-free
parser. They are merged with the platform-specific conditional.
(ft_lookup_PS_in_sfnt): Ditto.
* src/base/ftmac.c: Include ftbase.h.
(memory_stream_close): Removed.
(new_memory_stream): Ditto.
(open_face_from_buffer): Removed. Use the implementation in

2008-10-01 Werner Lemberg <wl@gnu.org>
* src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c
(cff_face_done), src/pfr/pfrobjs.c (pfr_face_done),
src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c
(cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done),
src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0.
Reported by Graham Asher.
2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/rules.mk: Add conditional source to BASE_SRC, for `make
multi' on Mac OS X. If the macro $(ftmac_c) is defined,
$(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the
lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
ftmac.c.
* builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
* builds/unix/configure.raw: Add procedure to set up appropriate
value of $(ftmac_c) with the consideration of the availability of
Carbon framework.
2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/Jamfile: Add target for multi build by jam on Mac OS X.
* src/base/ftobjs.c (FT_New_Face): Fix the condition to include this

src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.
2008-09-21 Werner Lemberg <wl@gnu.org>
* src/smooth/ftgrays.c (gray_raster_render): Don't dereference
`target_map' if FT_RASTER_FLAG_DIRECT is set. Problem reported by
Stephan T. Lavavej <stl@nuwen.net>.
2008-09-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/otvalid/Jamfile: Add missing target `otvmath' for multi build
by jam.

(gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
Use FT_TRACE7.
(gray_dump_cells): Make it `static void'.
(gray_convert_glyph): Use FT_TRACE7.
(FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
ftoutln.c.
* src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
FT_ERROR_BASE.
* docs/formats.txt: Updated.
2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

CID-keyed font support.
* builds/mac/ftmac.c: Ditto.
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
face from the buffer, so the caller must not free it.
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.

Type1 and sfnt-wrapped CID-keyed font support.
2008-09-18 Werner Lemberg <wl@gnu.org>
* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
orthogonality (ft_free and ft_sfree could belong to different memory
pools). This fixes Savannah bug #24297.
2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
in ttags.h instead of numerical value 0x4F54544FL.
2008-09-16 Werner Lemberg <wl@gnu.org>
* src/cff/cffgload.h, src/cff/cffgload.c
(cff_decoder_set_width_only): Eliminate function call.
2008-09-15 George Williams <gww@silcom.com>

of default values.
2008-09-15 Werner Lemberg <wl@gnu.org>
* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
prevent unconditional definition. This fixes Savannah bug #24241.
* src/psnames/pstables.h: Regenerated.
2008-09-13 Werner Lemberg <wl@gnu.org>
* autogen.sh, builds/unix/configure.raw,
include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
beautifying.
* include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
include/freetype/ftlcdfil.h: Protect against FreeType 1.
Some other minor fixes.
* devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.
2008-09-11 Werner Lemberg <wl@gnu.org>
* src/base/ftbase.c: Include ftadvanc.c.
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
results.
New option --{enable|disable}-biarch-config is added to define or
undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
ApplicationService framework is missing. Although this value is not
used in building of FreeType2, it is written in `freetype2.pc' and
`freetype-config'.
2008-09-01 david turner <david@freetype.org>
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
index to mean `use default cached FT_Face's charmap'. This fixes
Savannah bug #22625.
* include/freetype/ftcache.h: Document it.
Make FT_MulFix an inlined function. This is done to speed up
FreeType a little (on x86 3% when loading+hinting, 10% when
rendering, ARM savings are more important though). Disable this by
undefining FT_CONFIG_OPTION_INLINE_MULFIX.
Use of assembler code can now be controlled with
FT_CONFIG_OPTION_NO_ASSEMBLER.
* include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler
implementation.
[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler
implementation taken from `ftcalc.c'.
[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
which is defined to the platform-specific assembler implementation
of FT_MulFix.
[FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
(FT_MULFIX_INLINED): New macro.
* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
* include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
FT_MULFIX_INLINED.
Add a new header named FT_ADVANCES_H declaring some new APIs to
extract the advances of one or more glyphs without necessarily
loading their outlines. Also provide `fast loaders' for the
TrueType, Type1, and CFF font drivers (more to come later).
* src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
* include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.
* include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
`flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
respectively.
* src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add
ftadvanc.c.
* src/cff/cffdrivr.c (cff_get_advances): New function.
(cff_driver_class): Register it.
* src/cff/cffgload.c (cff_decoder_set_width_only): New function.
(cff_decoder_parse_charstrings): Handle `width_only'.
(cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.
* src/cff/cffgload.h (cff_decoder): New element `width_only'.
(cff_decoder_set_width_only): New declaration.
* src/truetype/ttdriver.c (tt_get_advances): New function.
(tt_driver_class): Register it.
* src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
(TT_Get_HMetrics, TT_Get_VMetrics): This.
Update callers.
* src/truetype/ttgload.h: Declare them.
* src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
function.
* src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.
Add checks for minimum version of the `autotools' stuff.
* autogen.sh: Implement it.
(get_major_version, get_minor_version, get_patch_version,
compare_to_minimum_version, check_tool_version): New auxiliary
functions.
* README.CVS: Document it.
2008-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).
2008-08-28 Werner Lemberg <wl@gnu.org>
* src/type1/t1load.c (parse_encoding): Protect against infinite
loop. This fixes Savannah bug #24150 (where a patch has been posted
too).
2008-08-23 Werner Lemberg <wl@gnu.org>
* src/type/t1afm.c (compare_kern_pairs), src/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'.
* src/cod/cidtoken.h: Handle `ForceBold' keyword.
Don't handle `ExpansionFactor'.
2008-08-04 Bram Tassyns <bramt@enfocus.be>
* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
resulted in incorrect scaling. This fixes Savannah bug #23973.
2008-08-04 Werner Lemberg <wl@gnu.org>
Be more tolerant w.r.t. invalid entries in SFNT table directory.
* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
adjust table count.
Add more trace messages.
(tt_face_load_font_dir): Updated.
2008-07-30 Werner Lemberg <wl@gnu.org>
* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
assume that the first argument on the stack is the bottom-most
element. Two reasons:
o According to people from Adobe it is missing in the Type 2
specification that pushing of additional, superfluous arguments
on the stack is prohibited.
o Acroread in general handles fonts differently, namely by popping
the number of arguments needed for a particular operand (as a PS
interpreter would do). In case of buggy fonts this causes a
different interpretation which of the elements on the stack are
superfluous and which not.
Since there are CFF subfonts (embedded in PDFs) which rely on
Acroread's behaviour, FreeType now does the same.
2008-07-27 Werner Lemberg <wl@gnu.org>
Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
fixes Savanna bug #23940.
* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
(EXTRA_GLYPH_LIST_SIZE): This.
Increase by 2.
(ft_wgl_extra_unicodes): Rename to...
(ft_extra_glyph_unicodes): This.
Add two code values.
(ft_wgl_extra_glyph_names): Rename to...
(ft_extra_glyph_names): This.
Add two glyphs.
(ft_wgl_extra_glyph_name_offsets): Rename to...
(ft_extra_glyph_name_offsets): This.
Add two offsets.
(ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
(ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
Updated.
(ps_unicodes_init): Updated.
2008-07-26 Werner Lemberg <wl@gnu.org>
* src/cff/cffgload.c (cff_decoder_prepare,
cff_decoder_parse_charstrings): Improve debug output.
2008-07-22 Martin McBride <mmcbride@emtex.com>
* src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
tt_cmap4_char_map_binary): Handle fonts which treat the last segment
specially. According to the specification, such fonts would be
invalid but acroread accepts them.
2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk>
* src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
* src/base/ftcalc.c (FT_MulFix): Fix portability issue.
* src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
Fix compiler warning.
2008-07-16 Werner Lemberg <wl@gnu.org>
Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.
* src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
Invert sids table only if `pure_cff' is set.
* src/cff/cffload.h: 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 ...)'.
* docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
it.
2008-07-04 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
pixel, only check for dropouts if neither start nor end point lies
on a pixel center. This fixes Savannah bug #23762.
2008-06-29 Werner Lemberg <wl@gnu.org>
* Version 2.3.7 released.
=========================
Tag sources with `VER-2-3-7'.
* docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
version number to 2.3.7.
* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj,
builds/win32/visualce/index.html,
builds/win32/visualce/freetype.dsp,
builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
* builds/unix/configure.raw (version_info): Set to 9:18:3.
* docs/release: Updated.
2008-06-28 Werner Lemberg <wl@gnu.org>
* src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
* src/ftcalc.c: Here. This fixes Savannah bug #23729.
2008-06-27 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Test for intersections which
degenerate to a single point can be ignored; this has been confirmed
by Greg Hitchcock from Microsoft. (This was commented out code.)
2008-06-26 Werner Lemberg <wl@gnu.org>
Improve navigation in API reference.
* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
(html_header_6): This.
(html_header_3, html_header_3i, html_header_4, html_header_5,
html_header_5t): New strings.
(toc_footer_start, toc_footer_end): New strings.
(HtmlFormatter::html_header): Updated.
(HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
New strings.
(HtmlFormatter::index_enter): Use `html_index_header'.
(HtmlFormatter::index_exit): Print `html_footer'.
(HtmlFormatter::toc_enter): Use `html_toc_header'.
(HtmlFormatter::toc_exit): Print proper footer.
Convert ~ to non-breakable space.
* src/tools/docmaker/tohtml.py (make_html_para): Implement it.
Update header files accordingly.
2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
ResourceIndex type definition. The macro does not inform the type
availability.
* src/base/ftmac.c: More parentheses are inserted to clarify the
conditionals to disable legacy APIs in `10.5 and later' cases. If
HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
2008-06-24 Werner Lemberg <wl@gnu.org>
* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
mode.
* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
Draw_Sweep): No-dropout mode is value 2, not value 0.
(Draw_Sweep): Really skip dropout handling for no-dropout mode.
2008-06-24 Werner Lemberg <wl@gnu.org>
* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
if it consists of one point only. Based on a patch from Savannah
bug #23683 (from John Tytgat).
2008-06-22 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
with IS_HINTED.
* docs/CHANGES: Updated.
2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
but LDFLAGS does not, import it to LDFLAGS. The option is used to
specify non-default SDK on Mac OS X (e.g., universal binary SDK for
Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
recommends to add the option only to CFLAGS, LDFLAGS should include
it because libfreetype.la is built with -no-undefined. This fixes a
bug reported by Ryan Schmidt in MacPorts,
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.
Pass dropout rules from the TT bytecode interpreter to the
rasterizer.
* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
OpenType specification.
Fix mode 4 computation.
(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
mode to FT_OUTLINE_XXX flags.
* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
2008-06-19 Werner Lemberg <wl@gnu.org>
* src/cff/cffobjs.c (cff_face_init): Compute final
`dict->units_per_em' value before assigning it to
`cffface->units_per_EM'. Otherwise, CFFs without subfonts are
scaled incorrectly if the font matrix is non-standard. This fixes
Savannah bug #23630.
* docs/CHANGES: Updated.
2008-06-19 Werner Lemberg <wl@gnu.org>
* src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
from 2008-06-19.
2008-06-18 Werner Lemberg <wl@gnu.org>
* src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.
Reported by Peter Weilbacher <mozilla@weilbacher.org>.
* docs/CHANGES: Updated.
2008-06-15 George Williams <gww@silcom.com>
* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
`valid->extra2' to 1. This is undocumented in the OpenType 1.5
specification.
2008-06-15 Werner Lemberg <wl@gnu.org>
* src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
from clobbering. Patch from Savannah bug report #23556.
* docs/CHANGES: Document it.
2008-06-10 Werner Lemberg <wl@gnu.org>
* autogen.sh: Add option `--install' to libtoolize.

builds/win32/visualce/freetype.dsp,
builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/.
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 6.
* builds/unix/configure.raw (version_info): Set to 9:17:3.
* include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x'
and `scale_y'.
* src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'.
* src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H.
* src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
2008-06-10 Werner Lemberg <wl@gnu.org>
* src/base/ftobjs.c (open_face): Check `clazz->init_face' and
`clazz->done_face'.
2008-06-09 VaDiM <s_sliva@rambler.ru>
Support debugging on WinCE. From Savannah patch #6536; this fixes
bug #23497.
* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
as a replacement for OutputDebugStringA (which WinCE doesn't have).
Update all callers.
(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
environment variables.
2008-06-09 Werner Lemberg <wl@gnu.org>
* README.CVS: Updated.
* builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
for newer versions of autoconf and friends.
2008-06-08 Werner Lemberg <wl@gnu.org>
* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
`private_len' unsigned.
* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
it as such.
(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
for sane value.
Fix typo.
* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
`last_point'.
* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
`maxTwilightPoints'.
2008-06-06 Werner Lemberg <wl@gnu.org>
* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
2008-06-03 Werner Lemberg <wl@gnu.org>
* include/freetype/ftcache.h (FTC_FaceID): Change type back to
FT_Pointer. Reported by Ian Britten <britten@caris.com>.
2008-06-02 Werner Lemberg <wl@gnu.org>
Emit header info for defined FreeType objects in reference.
* src/tools/docmaker/content.py (re_header_macro): New regexp.
(ContentProcessor::__init__): Initialize new dictionary `headers'.
(DocBlock::__init__): Collect macro header definitions.
* src/tools/docmaker/tohtml.py (header_location_header,
header_location_footer): New strings.
(HtmlFormatter::__init__): Pass `headers' dictionary.
(HtmlFormatter::print_html_field): Don't emit paragraph tags.
(HtmlFormatter::print_html_field_list): Emit empty paragraph.
(HtmlFormatter::block_enter): Emit header info.
2008-06-01 Werner Lemberg <wl@gnu.org>
* include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
FT_INCREMENTAL_H): Added.
2008-05-28 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/sources.py (SourceBlock::__init__): While
looking for markup tags, return immediately as soon a single one is
found.
2008-05-28 Werner Lemberg <wl@gnu.org>
* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
original, unscaled input values. Confirmed by Greg Hitchcock from
Microsoft.
2008-05-27 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py (block_footer_start,
block_footer_middle): Beautify output.
2008-05-25 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c (fc_black_render): Return 0 when we are
trying to render into a zero-width/height bitmap, not an error code.
* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
of the graphics state for subglyphs to...
(TT_Hint_Glyph): This function.
Hinting instructions for a composite glyph apparently refer to the
just hinted subglyphs, not the unhinted, unscaled outline. This
seems to fix Savannah bugs #20973 and (at least partially) #23310.
2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
`aface' is returned by FT_New_Face_From_FOND(). The patch was
proposed by an anonymous reporter of Savannah bug #23204.
2008-05-18 Werner Lemberg <wl@gnu.org>
* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
correction for pixel boundary. Without this patch, the effect can
be cumulative under certain circumstances, making glyphs taller and
taller after each call. This fixes Savannah bug #19976.
2008-05-18 Werner Lemberg <wl@gnu.org>
* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
This fixes Savannah bug #23280.
* docs/CHANGES: Updated.
2008-05-18 David Turner <david@freetype.org>
* src/psnames/psmodule.c (ft_wgl_extra_unicodes,
ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
declarations non-global.
* src/type1/t1load.c: Add missing comment.
2008-05-17 Sam Hocevar <samh>
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
glyphs correctly. Patch from Savannah bug #23277.
2008-05-16 Werner Lemberg <wl@gnu.org>
* docs/CHANGES: Updated.
2008-05-16 Sergey Tolstov <stolstov@esri.com>
Improve support for WGL4 encoded fonts.
* src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): New macro.
(ft_wgl_extra_unicodes, ft_wgl_extra_glyph_names,

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
(cf. the PS reference manual).
Reported by Martin McBride.
2008-05-15 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.
2008-05-15 Werner Lemberg <wl@gnu.org>
* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
which contains a single but empty entry. This is technically
invalid (since it must end with `return'), but...
Reported by Martin McBride.

Finish fix of scaling bug of CID-keyed CFF subfonts.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).
* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results. This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.
* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.

Handle case `face_index < 0'.
* docs/CHANGES: Document it.
2008-05-04 Werner Lemberg <wl@gnu.org>
First steps to fix the scaling bug of CID-keyed CFF subfonts,
reported by Ding Li on 2008/03/28 on freetype-devel.
* src/base/cff/cffparse.c (power_tens): New array.
(cff_parse_real): Rewritten to introduce a fourth parameter which
returns the `scaling' of the real number so that we have no
precision loss. This is not used yet.
Update all callers.
(cff_parse_fixed_thousand): Replace with...
(cff_parse_fixed_scaled): This function. Update all callers.
2008-05-03 Werner Lemberg <wl@gnu.org>
* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
transformation since it recursively calls FT_Load_Glyph. This fixes
Savannah bug #23143.
2008-04-26 Werner Lemberg <wl@gnu.org>

Add build support for symbian platform. From Savannah bug #22440.
* builds/symbian/*: New files.
2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
synthesis. For any face of a specified FOND, always the name for
the first face was used. Except of a FOND that refers multiple
Type1 font files, wrong synthesized font names are not used at all,
so this is an invisible bug. A few limit checks are added too.
* builds/mac/ftmac.c: Ditto.
2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Split compiler option to link Carbon
frameworks to one option for CoreServices framework and another
option for ApplicationServices framework. The split options can be
managed by GNU libtool to avoid unrequired duplication when FreeType
is linked with other applications. Suggested by Daniel Macks,
Savannah bug #22366.
2008-02-18 Victor Stinner <victor.stinner@haypocalc.com>
* src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix
from Savannah bug #22356.
2008-02-17 Jonathan Blow <jon@number-none.com>
* src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
Check for valid callback pointers.
2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
handle by its value instead of ResError(), fix provided by Deron
Kazmaier. According to the Resource Manager Reference,
GetResource(), Get1Resource(), GetNamedResource(),
Get1NamedResource() and RGetResource() set noErr but return NULL
handle when they can not find the requested resource. These
functions never return undefined values, so it is sufficient to
check if the handle is not NULL.
* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
inclusion styles. Now it always includes src/base/ftmac.c;
builds/mac/ftmac.c is never included in any configuration.
* builds/unix/configure.raw: Print warning if configure is executed
with options to specify Carbon functionalities explicitly.
* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
included automatically and manual replacement is required.
2008-02-11 Werner Lemberg <wl@gnu.org>
* builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
(dos_setup), builds/freetype.mk (clean_project_dos,

[FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.
2008-01-10 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (load_truetype_glyph): Handle the case
where the number of contours in a simple glyph is zero (and which
does contain an entry in the `glyf' table). This fixes Savannah bug
#21990.
2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Formatting suggested by Sean McBride.

correctly.
2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Improvement of POSIX resource-fork accessor to load unsorted
references in a resource. In HelveLTMM (resource-fork PostScript
Type1 font bundled with Mac OS X since 10.3.x), the appearance order
of PFB chunks is not sorted; sorting the chunks by reference IDs is
required.
* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
type to store a pair of reference ID and offset to the chunk.
* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
sort FT_RFork_Ref by their reference IDs.
(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
sorted by reference ID.
2007-12-14 Werner Lemberg <wl@gnu.org>
* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
division too early; otherwise the most significant digit(s) of the
final result are lost as the value is truncated to an integer. This
fixes Savannah bug #21794 (where the patch has been posted too).
2007-12-06 Fix <4d876b82@gmail.com>
Pass options from one configure script to another as-is (not
expanded). This is needed for options like
--includedir='${prefix}/include'.
* builds/unix/detect.mk, configure: Prevent argument expansion in
call to the (real) `configure' script.
2007-12-06 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
TT_USE_BYTECODE_INTERPRETER isn't defined.
2007-12-06 Werner Lemberg <wl@gnu.org>
There exist CFFs which contain opcodes for the Type 1 operators
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
However, it doesn't harm to support them.
* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
`cff_op_closepath.'
(cff_argument_counts): Ditto.
(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
and 13 (hsbw) which are invalid in Type 2 charstrings.
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
support new pathname syntax `..namedfork/rsrc' to access a resource
fork on Mac OS X. The legacy syntax `/rsrc' does not work on
case-sensitive HFS+.
(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
buffer size to store a pathname.
* include/freetype/internal/ftrfork.h: Increment the number of
resource fork guessing rule.
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Improve the compile tests to search
Carbon functions.
* builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
The documents and comments for Mac OS X are improved by Sean
McBride.
* src/base/ftmac.c: Fix a comment.

warning.
2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
cannot mmap() the specified file and cannot seek to head of the
specified file, it returns NULL stream and FT_Open_New() returns the
error immediately. On MacOS, most legacy MacOS fonts fall into such
a scenario because their data forks are zero-sized and cannot be
sought. To proceed to guessing of resource fork fonts, the
functions for legacy MacOS font must properly handle the NULL stream
returned by FT_New_Stream().
* src/base/ftobjs.c (IsMacBinary): Return error
FT_Err_Invalid_Stream_Operation immediately when NULL stream is
passed.
(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
to fallback. Originally, legacy MacOS font is tested in the cases
of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
.dfont header is combined). Now the case of
FT_Err_Cannot_Open_Stream is included.
* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
skip FT_Stream_Seek(), which seeks to the head of stream, and
proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
for a NULL stream causes a Bus error on Mac OS X.
(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
immediately if passed stream is NULL.
(raccess_guess_apple_single): Ditto.
2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix for Carbon incompatibilities since Mac OS X 10.5,
proposed by Sean McBride.
* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
Carbon functions from a forked process is classified as unsafe
by Apple. All Carbon-dependent functions should be deprecated.
* src/base/ftmac.c: Use essential header files <Carbon/Carbon.h>
and <ApplicationServices/ApplicationServices.h> instead of
all-in-one header file <CoreServices/CoreServices.h>.
Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
genuine macro PATH_MAX.
Add fallback macro for kATSOptionFlagsUnRestrictedScope which
is not found in Mac OS X 10.0.
Multi-character constants ('POST', 'sfnt' etc) are replaced by
64bit constants calculated by FT_MAKE_TAG() macro.
For the index in the segment of resource fork, new portable
type ResourceIndex is introduced for better compatibility.
This type is since Mac OS X 10.5, so it is defined as short
when built on older platforms.
(FT_ATSFontGetFileReference): If build target is only the systems
10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
and newer or 64bit platform, because legacy type FSSpec type is
removed completely.
(FT_New_Face_From_FSSpec): Ditto.
2007-11-01 Werner Lemberg <wl@gnu.org>
* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
fixes Savannah bug #21485.
2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
can handle the font at all, then check `face_index'. Otherwise, the
driver might return the wrong error code. This fixes Savannah bug
#21468.
2007-10-21 Werner Lemberg <wl@gnu.org>
* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
support for bit 8 of the `fsSelection' field in the `OS/2' table.
MS is already using this; hopefully, this becomes part of OpenType
1.5.
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
(WWS_SUBFAMILY).
2007-10-20 Werner Lemberg <wl@gnu.org>
* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
Add `td.left' element to CSS.
(toc_section_enter): Use it.
2007-10-18 David Turner <david@freetype.org>
* include/freetype/freetype.h, src/base/ftobjs.c: Rename API
functions related to cmap type 14 support to the
`FT_Object_ActionName' scheme:
FT_Get_Char_Variant_index -> FT_Face_GetCharVariantIndex
FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
FT_Get_Variant_Selectors -> FT_Face_GetVariantSelectors
FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar
FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant
Update documentation accordingly.
* src/sfnt/ttcmap.c: Stronger cmap 14 validation.
Make the code a little more consistent with FreeType coding
conventions and modify the cmap14 functions that returned a newly
allocated array to use a persistent vector from the TT_CMap14 object
instead.
(TT_CMap14Rec): Provide array and auxiliary data for result.
(tt_cmap14_done, tt_cmap14_ensure): New functions.
(tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary,

* README, Jamfile (RefDoc), builds/win32/visualc/index.html,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/2.3.3/2.3.4/, s/233/234/.

interface (Savannah bug #19260).
2007-04-06 David Turner <david@freetype.org>
* src/base/ftbimap.c (ft_bitmap_assure_buffer): Fix buffer-overwrite bug
(Savannah bug #19536).

2007-04-03 David Turner <david@freetype.org>
* src/base/ftobjs.c (FT_Set_Char_Size): As suggested by James Cloos,
if one of the resolution values is 0, treat it as if it were the
same as the other value.
2007-04-02 David Turner <david@freetype.org>
Add special code to detect `extra-light' fonts and do not snap their
stem widths too much to avoid bizarre hinting effects.
* src/autofit/aflatin.h (AF_LatinAxisRec): Add `standard_width' and
`extra_light' members.
* src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize
them.
(af_latin_metrics_scale_dim): Set `extra_light'.
(af_latin_compute_stem_width): Use `extra_light'.

corresponding code.
(Ins_MD): Last regression fix.
* src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues

2007-01-30 David Turner <david@freetype.org>
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

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
prevented compilation when disabling both the unpatented and the
bytecode interpreter in the TrueType font driver.
Fix and enable the warper to improve `light' hinting mode. This is
not necessarily a final version, but it seems to work well.

The issue is that GNU libtool is called `glibtool' on this platform,
and we must call `glibtoolize', since `libtoolize' doesn't exist.

* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
correctly. This fixes Savannah bug #17876.
Do not allocate interpreter-specific tables in memory if we are not
going to load glyphs with the bytecode interpreter anyway.
* src/truetype/ttgload.c (tt_loader_init): Load execution context
only if glyph is hinted.
Updated.
* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
and `cvs_ready'.
Add `tt_size_ready_bytecode' declaration.
* src/truetype/ttobjs.c (tt_size_done_bytecode,
tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
(tt_size_init): Move most code into `tt_size_init_bytecode'.
(tt_size_done): Move most code into `tt_size_done_bytecode'.
(tt_size_reset): Move some code to `tt_size_ready_bytecode'.
Don't extract the metrics table from the SFNT font file. Instead,
reparse it on each glyph load. The runtime difference is not
noticeable, and it can save a lot of heap memory when memory-mapped
files are not used.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
`horz_metrics_offset' and `vert_metrics_ofset'.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
Updated.
* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
Do not load the CFF index offsets into memory, since this wastes a
*lot* of heap memory with large Asian CFF fonts. There is no
significant performance loss.
* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
`data_size'.
(CFF_CharsetRec): Add field `num_glyphs'.
* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
cff_charset_cid_to_gindex): New functions.
(cff_new_index): Renamed to...
(cff_index_init): This. Update all callers.
Updated -- some code has been moved to `cff_index_load_offsets'.
(cff_done_index): Renamed to...
(cff_index_done): This. Update all callers.
(cff_index_get_pointers, cff_index_access_element): Updated to use
stream offsets.
(cff_charset_compute_cids): Set `num_glyphs' field.
(cff_encoding_load): Updated.
* src/cff/cffgload.c (cff_slot_load): Updated.
2007-01-04 David Turner <david@freetype.org>

autogen.sh and pointer to README.CVS.
* README.CVS: Add common problem description and solution
when running autogen.sh.
* docs/INSTALL: Add reference to MacOS X.
* docs/MAKEPP, docs/INSTALL.MAC: New documentation files.
* docs/TODO: Remove obsolete items.
* src/raster/ftraster.c: (TRaster_Instance): Replace it with...
(TWorker): This.
Remove `count_table' and `memory'.
Make `grays' a pointer.
(TRaster): New structure.
(count_table): New static array.
(RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
ft_black_set_mode, ft_black_render): Updated.
(ft_black_init): Don't initialize `count_table'.
(ft_black_reset): Use the render pool. This saves about 6KB of
heap space for each FT_Library instance.
* src/smooth/ftgrays.c (TRaster): Replaced with...
(TWorker): This.
Remove `memory'.
(TRaster): New structure.
(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
gray_render_span, gray_raster_render): Updated.
(gray_raster_reset): Use the render pool. This saves about 6KB of
heap space for each FT_Library instance.
* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
the optimization is no longer experimental.
* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
Remove a typo that results in no hinting and a memory leak with some
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
CFF_Faces in it. We need to close all faces before destroying the
modules, or else some bad things (memory leaks) may happen.
2007-01-02 Werner Lemberg <wl@gnu.org>
* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
Remove compiler warning.
2007-01-02 David Turner <david@freetype.org>
* src/sfnt/sfobjs.c: Add documentation comment.

function.
Check uniqueness of the gid pairs.
(gxv_kern_subtable_fmt0_validate): Move some code to
`gxv_kern_subtable_fmt0_pairs_validate'.
2006-12-22 David Turner <david@freetype.org>
* src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
warnings.
* builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
to avoid deprecation warnings with Visual C++ 8.
2006-12-16 Anders Kaseorg <anders@kaseorg.com>
* src/base/ftlcdfil.c (FT_Library_SetLcdFilter)
[FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.
2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* include/freetype/internal/services/svotval.h: Add `volatile' to
sync with the modification by Jens Claudius on 2006-08-22; cf.
http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5
2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c: Specialized for Mac OS X only.
* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
* builds/unix/configure.raw: Ditto. When explicit switches for
FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
builds/mac/ftmac.c is used instead of default src/base/ftmac.c.
2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.

GNU make's built-in string functions.
(refdoc): Use $(version) instead of static version number.
2006-12-08 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk (dist): Extract version number from freetype.h.
2006-12-08 Vladimir Volovich <vvv@vsu.ru>
* src/tools/apinames (State): Remove final comma in structure -- xlc
v5 under AIX 4.3 doesn't like this.
2006-12-07 David Turner <david@freetype.org>
* src/autofit/afloader.c (af_loader_load_g): Small adjustment
to the spacing of auto-fitted glyphs. This only impacts rare
cases (e.g., Arial Bold at rather small character sizes).
2006-12-03 Werner Lemberg <wl@gnu.org>
* src/sfnt/rules.mk (SFNT_DRV_SRC): Add ttsbit0.c.
2006-12-01 Werner Lemberg <wl@gnu.org>
* src/sfnt/sfobjs.c (tt_face_get_name): All Unicode strings are
encoded in UTF-16BE. Patch from Rajeev Pahuja <rpahuja@esri.com>.

af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
Add stubs to link the `ftgrid' test program when debugging is
disabled in the auto-hinter.
2006-11-23 David Turner <david@freetype.org>
* src/autofit/afhints.c, src/autofit/afhints.h, src/autofit/aflatin.c,
src/autofit/aftypes.h: Miscellaneous auto-hinter improvements.

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

src/type1/t1gload.c (T1_Load_Glyph), src/winfonts/winfnt.c
(FNT_Load_Glyph): Check validity of `glyph_index'.
2006-11-13 David Turner <david@freetype.org>
* src/truetype/ttinterp.c (FIX_BYTECODE): Undefine. The interpreter
`enhancements' are still too buggy for general use.
* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros
when building the library to change the default LCD filter to be
used. This is only useful for experimentation.
* include/freetype/ftlcdfil.h: Update documentation.
2006-11-10 David Turner <david@freetype.org>
* src/smooth/ftsmooth.c: API change for the LCD
filter. The FT_LcdFilter value is an enumeration describing which
filter to apply, with new values FT_LCD_FILTER_LIGHT and
FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
algorithm which produces strong color fringes for everything
except very-well hinted text).
* include/freetype/ftlcdfil.h (FT_Library_SetLcdFilter): Change
second parameter to an enum type.
* src/base/ftlcdfil.c (USE_LEGACY): Define.

callback and update other fields.
* src/smooth/ftsmooth.c (ft_smooth_render_generic)
[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
Other minor improvements.

typo which created a variable-used-before-initialized bug.
2006-11-07 Zhe Su <james.su@gmail.com>
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle vertical layout
also.
2006-11-03 Werner Lemberg <wl@gnu.org>
* src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.
2006-11-02 David Turner <david@freetype.org>
Add a few tweaks to better handle serif fonts.
Add more debugging messages.
* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
segments that are less than 1.5 pixels high. This gets rid of
*many* corner cases with serifs.

_af_debug_disable_blue_hints, and _af_debug_hints variables.
* src/autofit/aftypes.h (AF_LOG) [AF_DEBUG]: Use _af_debug.
Update external declarations.
(af_corner_orientation, af_corner_is_flat): Replaced by...
* include/freetype/internal/ftcalc.h (ft_corner_orientation,
ft_corner_is_flat): These declarations.
* src/autofit/afangles.c (af_corner_orientation, af_corner_is_flat):
Comment out. Replaced by...
* src/base/ftcalc.h (ft_corner_orientation, ft_corner_is_flat):
These functions. Update all callers.
(FT_Add64) [!FT_LONG64]: Simplify.
* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
(af_direction_compute): Add a missing FT_ABS call. This bug caused
production of garbage by missing lots of segments.
* src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.
* src/autofit/afloader.c (af_loader_init, af_loader_done)
[AF_DEBUG]: Set _af_debug_hints.

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

(cff_charset_load): Call `cff_charset_compute_cids'.
(cff_encoding_load) <Populate>: Ditto, to replace inefficient loop.
* src/sfnt/ttmtx.c (tt_face_load_hmtx): Replace calls to FT_GET_XXX
with FT_NEXT_XXX.
Speed up the Postscript hinter, with more than 100% speed increase
on my machine.
* src/pshinter/pshalgo.c (psh_corner_is_flat,
psh_corner_orientation): New functions.

2006-10-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* docs/INSTALL.CROSS: New document file for cross-building.
* builds/unix/configure.raw: Preliminary cross-building support.
Find native C compiler and pass it by CC_BUILD, and
find suffix for native executable and pass it by EXEEXT_BUILD.
Also suffix for target executable is passed by EXEEXT.
* builds/unix/unix-cc.in (CCraw_build, E_BUILD): New variables to
build `apinames' which runs on building system. They are set by
CC_BUILD and EXEEXT_BUILD.
* builds/exports.mk (APINAMES_EXE): Change the extension for
apinames from the suffix for target (E) to that for building host
(E_BUILD).
2006-10-12 Werner Lemberg <wl@gnu.org>
* docs/INSTALL.UNX, docs/UPGRADE.UNX: Renamed to...
* docs/INSTALL.UNIX, docs/UPGRADE.UNIX: This. Update all documents
which reference those files.

2006-09-27 David Turner <david@freetype.org>
* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.
Add a new API to support color filtering of subpixel glyph bitmaps.
In a default build, the function `FT_Library_SetLcdFilter' returns
`FT_Err_Unimplemented_Feature'; you need to #define
FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
real implementation.
* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.
* include/freetype/internal/ftobjs.h (FT_Bitmap_LcdFilterFunc): New
typedef.

for patent reasons.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
isn't defined at compile time. This only changes the content of the
rendered glyph to match the one of normal gray-level rendering,
hence clients should not need to be modified.
* docs/CHANGES: Updated.
2006-09-18 Garrick Meeker <garrick@digitalanarchy.com>
* src/base/ftmac.c (FT_New_Face_From_FOND): Fall back to SFNT if

2006-09-11 David Turner <david@freetype.org>
* src/sfnt/sfobjs.c (tt_face_get_name): Support some fonts which
report their English names through an Apple Roman
(platform,encoding) pair, with language_id != English.
If the font uses another name entry with language_id == English, it
will be selected correctly, though.
* src/truetype/ttobjs.c (tt_face_init): Add unpatented hinting
selection for `mingli.ttf'.
2006-09-05 Werner Lemberg <wl@gnu.org>
* src/truetype/ttpload.c (tt_face_load_hdmx): Handle `record_size'
values which have the upper two bytes set to 0xFF instead of 0x00
(as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
`HAN NOM B.ttf').
* src/smooth/ftgrays.c [GRAYS_USE_GAMMA]: Really remove all code.
2006-09-05 David Turner <david@freetype.org>
Minor source cleanups and optimizations.
* src/smooth/ftgrays.c (GRAYS_COMPACT): Removed.
(TRaster): Remove `count_ex' and `count_ey'.

theoretically happen. This fixes Savannah bug #16669.
* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
of `face->num_glyphs' which missed the last glyph, due to
the offset-by-1 computation, since the PFR format doesn't

2006-05-17 David Turner <david@freetype.org>
This is a major patch used to drastically improve the performance of
loading glyphs. This both speeds up loading the glyph vectors
themselves and the auto-fitter module.

engine's performance.
The resulting speed-up is about 25%.

constant values out of the loops.
* src/autofit/aftypes.h: Updated.
* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
product to get orientation.
* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
(FT_Stream_OpenGzip): Use it to handle small files directly in
memory.
* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
Improve performance.
* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
`limit'.
(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
TT_Load_Composite_Glyph): Updated. Add threshold to protect against
exceedingly large values of number of contours. Speed up by

* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
used to detect rogue clients from 4 to 16. This is to prevent some
segmentation faults with fonts like `KozMinProVI-Regular.otf' which
comes from the Japanese Adobe Reader Asian Font pack.
2007-05-17 Werner Lemberg <wl@gnu.org>
* src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
fixes the first part of Savannah bug #16590.
