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. (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 be
scaled incorrectly if the font matrix is non-standard. This fixes
Savannah bug #23630.

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.

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.

`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.

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,
ft_wgl_extra_glyph_name_offsets): New arrays.
(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
(ps_unicodes_init): Use them to add additional Unicode mappings.
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.
2008-05-14 Werner Lemberg <wl@gnu.org>
Finish fix of scaling bug of CID-keyed CFF subfonts.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).
* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results. This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.
* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.

FT_ULong.
* docs/CHANGES: Document it.
2008-05-13 Werner Lemberg <wl@gnu.org>
* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
Handle case `face_index < 0'.
* docs/CHANGES: Document it.
2008-05-04 Werner Lemberg <wl@gnu.org>
First steps to fix the scaling bug of CID-keyed CFF subfonts,
reported by Ding Li on 2008/03/28 on freetype-devel.
* src/base/cff/cffparse.c (power_tens): New array.
(cff_parse_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>
* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'
and `scale_y' as obsolete since they aren't used.

* src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to
`FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZ'. From Savannah
bug #22909.
2008-04-13 Werner Lemberg <wl@gnu.org>
* src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
integer part is zero.
2008-04-01 Werner Lemberg <wl@gnu.org>
Fix compilation with g++ 4.1 (with both `single' and `multi'
targets).
* src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
which is crossed by a `goto'.
* src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
2008-03-31 Werner Lemberg <wl@gnu.org>
Fix support for subsetted CID-keyed CFFs.

* src/cid/cidriver.c: Include FT_SERVICE_CID_H.
(cid_get_ros): New function.
(cid_service_cid_info): New service structure.
(cid_services): Register it.
2008-03-23 Werner Lemberg <wl@gnu.org>

(ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
2008-03-21 Laurence Darby <ldarby>
* src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from
Savannah bug #22675.
2008-03-13 Derek Clegg <dclegg@apple.com>
* src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.
Patch from Savannah bug #22541.
2008-03-03 Masatoshi Kimura <VYV03354@nifty.ne.jp>
* src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
tt_cmap14_find_variant): Return correct value.
(tt_cmap14_variant_chars): Fix check for `di'.
2008-02-29 Wermer Lemberg <wl@gnu.org>
* docs/CHANGES: Updated.
2008-02-29 Wolf
Add build support for symbian platform. From Savannah bug #22440.
* builds/symbian/*: New files.
2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
synthesis. For any face of a specified FOND, always the name for
the first face was used. Except of a FOND that refers multiple
Type1 font files, wrong synthesized font names are not used at all,
so this is an invisible bug. A few limit checks are added too.
* builds/mac/ftmac.c: Ditto.
2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Split compiler option to link Carbon
frameworks to one option for CoreServices framework and another
option for ApplicationServices framework. The split options can be
managed by GNU libtool to avoid unrequired duplication when FreeType
is linked with other applications. Suggested by Daniel Macks,
Savannah bug #22366.
2008-02-18 Victor Stinner <victor.stinner@haypocalc.com>
* src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix
from Savannah bug #22356.
2008-02-17 Jonathan Blow <jon@number-none.com>
* src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
Check for valid callback pointers.
2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
handle by its value instead of ResError(), fix provided by Deron
Kazmaier. According to the Resource Manager Reference,
GetResource(), Get1Resource(), GetNamedResource(),
Get1NamedResource() and RGetResource() set noErr but return NULL
handle when they can not find the requested resource. These
functions never return undefined values, so it is sufficient to
check if the handle is not NULL.
* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
inclusion styles. Now it always includes src/base/ftmac.c;
builds/mac/ftmac.c is never included in any configuration.
* builds/unix/configure.raw: Print warning if configure is executed
with options to specify Carbon functionalities explicitly.
* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
included automatically and manual replacement is required.
2008-02-11 Werner Lemberg <wl@gnu.org>
* builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
(dos_setup), builds/freetype.mk (clean_project_dos,
distclean_project_dos): Don't use \ but $(SEP). Reported by Duncan
Murdoch.
2008-01-18 Sylvain Pasche <sylvain.pasche@gmail.com>
* src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to
mention intra-pixel algorithm.
* include/freetype/freetype.h (FT_Render_Mode): Mention that
FT_Library_SetLcdFilter can be used to reduce fringes.
2008-01-16 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c (ft_black_render): Check `outline' before
using it. Reported by Allan Yang.
2008-01-12 Werner Lemberg <wl@gnu.org>
* src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove.
2008-01-12 Allan Yang, Jian Hua - SH <Allan.Yang@fmc.fujitsu.com>
* src/raster/ftraster.c (ft_black_init)
[FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.
2008-01-10 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (load_truetype_glyph): Handle the case
where the number of contours in a simple glyph is zero (and which
does contain an entry in the `glyf' table). This fixes Savannah bug
#21990.
2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Formatting suggested by Sean McBride.
* builds/mac/ftmac.c: Formatting (tab expanded).
* src/autofit/afindic.c: Ditto.
* src/base/ftcid.c: Ditto.
* src/base/ftmac.c: Ditto.
2007-12-30 Werner Lemberg <wl@gnu.org>
* src/smooth/ftgrays.c (gray_raster_render): Check `outline'
correctly.
2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Improvement of POSIX resource-fork accessor to load unsorted
references in a resource. In HelveLTMM (resource-fork PostScript
Type1 font bundled with Mac OS X since 10.3.x), the appearance order
of PFB chunks is not sorted; sorting the chunks by reference IDs is
required.
* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
type to store a pair of reference ID and offset to the chunk.
* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
sort FT_RFork_Ref by their reference IDs.
(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
sorted by reference ID.
2007-12-14 Werner Lemberg <wl@gnu.org>
* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
division too early; otherwise the most significant digit(s) of the
final result are lost as the value is truncated to an integer. This
fixes Savannah bug #21794 (where the patch has been posted too).
2007-12-06 Fix <4d876b82@gmail.com>
Pass options from one configure script to another as-is (not
expanded). This is needed for options like
--includedir='${prefix}/include'.
* builds/unix/detect.mk, configure: Prevent argument expansion in
call to the (real) `configure' script.
2007-12-06 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
TT_USE_BYTECODE_INTERPRETER isn't defined.
2007-12-06 Werner Lemberg <wl@gnu.org>
There exist CFFs which contain opcodes for the Type 1 operators
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
However, it doesn't harm to support them.
* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
`cff_op_closepath.'
(cff_argument_counts): Ditto.
(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
and 13 (hsbw) which are invalid in Type 2 charstrings.
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
support new pathname syntax `..namedfork/rsrc' to access a resource
fork on Mac OS X. The legacy syntax `/rsrc' does not work on
case-sensitive HFS+.
(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
buffer size to store a pathname.
* include/freetype/internal/ftrfork.h: Increment the number of
resource fork guessing rule.
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Improve the compile tests to search
Carbon functions.
* builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
The documents and comments for Mac OS X are improved by Sean
McBride.
* src/base/ftmac.c: Fix a comment.
* include/freetype/ftmac.h: Ditto.
* docs/INSTALL.MAC: Improve English and add comment on lowest
system version specified by MACOSX_DEPLOYMENT_TARGET.
2007-12-04 Werner Lemberg <wl@gnu.org>
* src/cff/cffload.c (cff_subfont_load): Don't use logical OR to
concatenate error codes.
* src/sfnt/ttsbit.c (Load_SBit_Range): Ditto.
2007-12-04 Graham Asher <graham.asher@btinternet.com>
* src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
concatenate error codes.
2007-12-04 Sean McBride <sean@rogue-research.com>
* src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler
warning.
2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
cannot mmap() the specified file and cannot seek to head of the
specified file, it returns NULL stream and FT_Open_New() returns the
error immediately. On MacOS, most legacy MacOS fonts fall into such
a scenario because their data forks are zero-sized and cannot be
sought. To proceed to guessing of resource fork fonts, the
functions for legacy MacOS font must properly handle the NULL stream
returned by FT_New_Stream().
* src/base/ftobjs.c (IsMacBinary): Return error
FT_Err_Invalid_Stream_Operation immediately when NULL stream is
passed.
(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
to fallback. Originally, legacy MacOS font is tested in the cases
of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
.dfont header is combined). Now the case of
FT_Err_Cannot_Open_Stream is included.
* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
skip FT_Stream_Seek(), which seeks to the head of stream, and
proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
for a NULL stream causes a Bus error on Mac OS X.
(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
immediately if passed stream is NULL.
(raccess_guess_apple_single): Ditto.
2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix for Carbon incompatibilities since Mac OS X 10.5,
proposed by Sean McBride.
* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
Carbon functions from a forked process is classified as unsafe
by Apple. All Carbon-dependent functions should be deprecated.
* src/base/ftmac.c: Use essential header files <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>

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.

corresponding code.
(Ins_MD): Last regression fix.

(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

* 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_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/cfftypes.h (CFF_IndexRec): Add fields `start' and
`data_size'.

* 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.

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>

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>

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.

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

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.

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>

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_LibraryRec) [FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Add filtering
callback and update other fields.
* src/smooth/ftsmooth.c (ft_smooth_render_generic)
[FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Update.
Other minor improvements.
* src/autofit/aflatin.c: Various tiny improvements that drastically
improve the handling of serif fonts and of LCD/LCD_V hinting modes.
(af_latin_hints_compute_edges): Fix typo.
(af_latin_compute_stem_width): Take better care of diagonal stems.
2006-11-09 David Turner <david@freetype.org>
* src/pshinter/pshalgo.c (psh_glyph_compute_inflections): Fix
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_latin_hint_edges): Use AF_HINTS_DO_BLUES.
Add logging messages.
Handle AF_EDGE_FLAG flag specially.

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.
* src/pshinter/pshalgo.c: Include FT_INTERNAL_CALC_H.
(psh_corner_is_flat, psh_corner_orientation): Use ft_corner_is_flat
and ft_corner_orientation.
* src/gzip/inftrees.c (huft_build): Remove compiler warning.
2006-10-24 Werner Lemberg <wl@gnu.org>
* src/cff/cffload.c (cff_encoding_load): Remove unused variable.
* src/base/ftobjs.c (FT_Select_Charmap): Disallow FT_ENCODING_NONE
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_done): Call `cff_charset_free_cids'.

Add a new API to support color filtering of subpixel glyph bitmaps.
In a default build, the function `FT_Library_SetLcdFilter' returns

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.

* 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):
Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.
2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* build/unix/configure.raw: Add a fallback to disable Carbon
dependency, if configured with no options on Mac OS X.
2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
its content cannot be parsed as supported font. This fixes
the second part of Savannah bug #16590.
2006-05-18 Werner Lemberg <wl@gnu.org>
* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
[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.
