2007-02-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* include/freetype/ftmac.h: Fixed wrong comment, FSSpec of
FT_GetFile_From_Mac_Name, FT_GetFile_From_Mac_ATS_Name are
for passing to FT_New_Face_From_FSSpec.
2007-02-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Checks if Mac OS X system headers
can be built under ANSI C mode.
* src/base/ftmac.c (OS_INLINE): Redefine OS_INLINE by ANSI C
compatible one, if system headers are ANSI C incompatible.
* builds/mac/ftmac.c (OS_INLINE): Ditto.
2007-02-01 Werner Lemberg <wl@gnu.org>
* include/freetype/ttnameid.h (TT_MS_LANGID_DZONGHKA_BHUTAN):
Explain why applications shouldn't use it. Found by Alexei.
2007-02-01 Alexei Podtelezhnikov <apodtele@gmail.com>
* builds/unix/freetype2.m4 (AC_CHECK_FT2): Fix spelling of warning
message.
* src/gxvalid/gxvmort1.c
(gxv_mort_subtable_type1_substTable_validate): Fix debugging
message.
2007-01-31 Werner Lemberg <wl@gnu.org>
* Version 2.3.1 released.
=========================
Tag sources with `VER-2-3-1-FINAL'.
* builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/230/231/.
* builds/win32/visualc/index.html: s/221/231/.
* vms_make.com: Add `ftgasp'.
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
normal/full hinting to its normal quality.
* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
and `xmax_delta'.
* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
and `xmax_delta'.
* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
preprocessor conditional with if-clause, handling both light and
normal mode.
* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.
(af_warper_compute): Handle `xmin_delta' and `xmax_delta'.
2007-01-25 Werner Lemberg <wl@gnu.org>
* docs/release: Updated -- Savannah uses a new uploading scheme.
2007-01-25 David Turner <david@freetype.org>
* src/cff/cffload.c (cff_index_get_pointers): Improve previous fix.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)
<cff_op_callsubr, cff_op_callgsubr>: Fix sanity check for empty
functions.
* docs/CHANGES: Document light auto-hinting improvement.
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.
* src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
Disable code.
(af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
* src/autofit/aftypes.h: Activate AF_USE_WARPER.
* src/autofit/afwarp.c (AF_WarpScore): Tune table.
(af_warper_compute_line_best): Fix array size of `scores'.
(af_warper_compute): Better handling of border cases.
* src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
and `X2'.
2007-01-21 Werner Lemberg <wl@gnu.org>
* ChangeLog: Split off older entries into...
* ChangeLog.22: This new file.
2007-01-21 Werner Lemberg <wl@gnu.org>
* docs/CHANGES: Document SHZ fix.
2007-01-21 George Williams <gww@silcom.com>
* src/truetype/ttinterp.c (Ins_SHZ): SHZ doesn't move phantom
points.
2007-01-21 Werner Lemberg <wl@gnu.org>
* src/sfnt/ttmtx.c (tt_face_get_metrics)
[!FT_CONFIG_OPTION_OLD_INTERNALS]: Fix limit check.
2007-01-17 Werner Lemberg <wl@gnu.org>

* builds/amiga/include/freetype/config/ftconfig.h: Synchronize.
2007-01-14 Detlef Würkner <TetiSoft@apg.lahn.de>
Fix various compiler warnings.
* src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h,
src/cff/cffobjs.c (cff_size_request), src/type42/t42objs.h:
s/index/strike_index/.
* src/base/ftobjs.c (FT_Match_Size): s/index/size_index/.
* src/gxvalid/gxvmorx5.c
(gxv_morx_subtable_type5_InsertList_validate): s/index/table_index/.
* src/truetype/ttinterp.c (Compute_Point_Displacement),
src/pcf/pcfread.c (pcf_seek_to_table_type): Avoid possibly
uninitialized variables.
2007-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

with C++ compiler.
* src/autofit/afhints.c (af_glyph_hints_dump_segments,
af_glyph_hints_dump_edges): Ditto.
* src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in
`modules.cfg').
* src/sfnt/ttsbit0.h: Remove.
* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.
2007-01-12 David Turner <david@freetype.org>

* src/base/ftobjs.c (IsMacResource): Fix a small bug that caused a
crash with some Mac OS X .dfont files. Submitted by Masatake
Yamato.
* autogen.sh: Small fix to get it working on Mac OS X properly:
The issue is that GNU libtool is called `glibtool' on this platform,
and we must call `glibtoolize', since `libtoolize' doesn't exist.
2007-01-10 David Turner <david@freetype.org>
* all-sources: Tag all sources with VER-2-3-0-RC1 and
VER-2-3-0.
* Jamfile (RefDoc), README, builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj, docs/VERSION.DLL: Update
version number to 2.3.0.

values.
2007-01-08 David Turner <david@freetype.org>
* docs/CHANGES: Updated.

a new API `FT_Get_Gasp' to return entries of the `gasp' table
corresponding to a given character pixel size.
* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
`gasp' table, in order to avoid potential problems with later
versions.

2007-01-06 Werner Lemberg <wl@gnu.org>
* src/cff/cffload.c (cff_index_init): Remove unused variable.
(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.
2007-01-04 David Turner <david@freetype.org>
* 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>

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.
2006-12-31 Masatake YAMATO <jet@gyve.org>
* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New
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.

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.

instead of src/base/ftmac.c
* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
* builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
that cannot be built at present.
2006-12-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftobjs.c: Improvement of resource fork handler for
POSIX, cf.
http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
format or .dfont, to simulate the face index number counted by ftmac.c.
(IsMacResource): Return the number of scalable faces correctly.
2006-12-10 Werner Lemberg <wl@gnu.org>
* builds/toplevel.mk (version): Protect against `distclean' target.
2006-12-09 Werner Lemberg <wl@gnu.org>

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>.
(tt_name_entry_ascii_from_ucs4): Removed.

appears in the documentation.
* include/freetype/ftchapters.h: Add `font_format' section.
* src/tools/docmaker/tohtml.py (HtmlFormatter::index_exit): Add link
to TOC in index page.
2006-11-28 David Turner <david@freetype.org>
* src/smooth/ftgrays.c (gray_raster_render): Return 0 when we are
trying to render into a zero-width/height bitmap, not an error code.
* src/truetype/ttobjs.c (tt_face_init): Fix typo in previous patch.
* src/smooth/ftgrays.c: Remove hard-coded error values; use FreeType
ones instead.

variable.
2006-11-26 Pierre Hanser <hanser@club-internet.fr>
* src/truetype/ttobjs.c (tt_face_init): Protect against NULL pointer.
2006-11-25 David Turner <david@freetype.org>
* src/autofit/afhints.c (af_glyph_hints_dump_points,
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,

Improve handling of remaining edges.
2006-11-22 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #15553.
* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
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
(pfr_slot_load), src/truetype/ttdriver.c (Load_Glyph),
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.
(_ft_lcd_filter): Rename to...

data and check that tables don't overlap (using a simple
bubblesort).
(PCF_METRIC_SIZE, PCF_COMPRESSED_METRIC_SIZE, PCF_PROPERTY_SIZE):
New macros which give the size of data structures in the data
stream.
(pcf_get_properties): Use rough estimates to get array size limits.
Assign `face->nprops' and `face->properties' earlier so that a call
to PCF_Face_Done can do the clean-up in case of error.
Protect against invalid string offsets.
(pcf_get_metrics): Clean up code.
Adjust tracing message levels.
Use rough estimate to get array size limit.

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

Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
Mac. The original patch was written by David Sachitano and Lawrence
Coopet, and modified by Sean McBride for MPW compatibility. Only
required data are converted; unused data are left in big endian.
* src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
Mac OS X platforms.
(OS_INLINE): Undefine before definition.
(count_faces_sfnt): Insert EndianS16_BtoN to parse the header of
FontAssociation table in FOND resource.
(count_faces_scalable): Insert EndianS16_BtoN to parse the header
and fontSize at each entry of FontAssociation table in FOND
resource.
(parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to parse
ffStylOff of FamilyRecord header of FOND resource, the header,
fontSize, fontID at each entry of FontAssociation table, and
StyleMapping table.
(count_faces): Call `HUnlock' after all FOND utilization.
2006-06-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Public API of TrueTypeGX, OpenType, and classic kern table validator
should return `FT_Err_Unimplemented_Feature' if validation service
is unavailable (disabled in `modules.cfg'). It is originally
suggested by David Turner, cf.
http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html
* src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return
FT_Err_Unimplemented_Feature if TrueTypeGX validation service is
unavailable.
(FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if
classic kern table validation service is unavailable.
* src/base/ftotval.c (FT_OpenType_Validate): Return
FT_Err_Unimplemented_Feature if OpenType validation service is
unavailable.
2006-06-08 Werner Lemberg <wl@gnu.org>
* src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of
errors.
2006-06-07 David Turner <david@freetype.org>
* src/type1/t1afm.c (KERN_INDEX): Make it more robust.
(T1_Read_Metrics): Fix memory leak which happened when the metrics
file doesn't have kerning pairs. This fixes Savannah bug #16768.
2006-06-06 David Turner <david@freetype.org>
Fix memory leak described in Savannah bug #16759.
We change `ps_unicodes_init' so that it also takes a
`free_glyph_name' callback to release the glyph names returned by
`get_glyph_name'
* include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
Renamed to ...
(PS_GetGlyphNameFunc): This.
(PS_FreeGlyphNameFunc): New typedef.
(PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.
* src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
argument.
(cff_sid_free_glyph_name): New function.
(cff_cmap_unicode_init): Updated.
* src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated.
* src/psnames/psmodule.c (ps_unicodes_init): Add variable for
PS_FreeGlyphNameFunc and use it.
2006-06-04 David Turner <david@freetype.org>
* src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
`item_size == 0' as well -- though this sounds weird, it can
theoretically happen. This fixes Savannah bug #16669.
* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
of `face->num_glyphs' which missed the last glyph, due to
the offset-by-1 computation, since the PFR format doesn't
guarantee that glyph index 0 corresponds to the `missing
glyph. This fixes Savannah bug #16668.
2006-05-25 Werner Lemberg <wl@gnu.org>
* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
`-no-undefined'. Reported by Christian Biesinger.
2006-05-19 Brian Weed <bw@imaginengine.com>
* builds/win32/visualc/freetype.dsp: Release libraries no longer
have debug information, and debug libraries use `C7 compatible'
debug info.
2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Apply patch by Derek Clegg to fix two memory leaks in the MacOS
resource fork handler. This fixes Savannah bug #16631.
* src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
`FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.
* src/base/ftrfrk.c (raccess_guess_linux_double_from_file_name):

dependency, if configured with no options on Mac OS X.
2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
its content cannot be parsed as supported font. This fixes
the second part of Savannah bug #16590.
2006-05-18 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
2006-05-17 David Turner <david@freetype.org>
This is a major patch used to drastically improve the performance of
loading glyphs. This both speeds up loading the glyph vectors
themselves and the auto-fitter module.
We now use inline assembler code with GCC to implement `FT_MulFix',
which is probably the most important function related to the
engine's performance.
The resulting speed-up is about 25%.
* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
`cursor' and `limit'.
* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
New functions.
(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
[TEST]: Remove.
* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
code.
* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
`FT_ZERO'
(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
(af_glyph_hints_reload: Rewrite recognition of weak points.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
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
reducing the number of loops.
* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
used to detect rogue clients from 4 to 16. This is to prevent some
segmentation faults with fonts like `KozMinProVI-Regular.otf' which
comes from the Japanese Adobe Reader Asian Font pack.
2007-05-17 Werner Lemberg <wl@gnu.org>
* src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
fixes the first part of Savannah bug #16590.
2006-05-16 Werner Lemberg <wl@gnu.org>
* docs/PROBLEMS: Updated icl issues.
