Release Name: 2.3.6
Notes:
CHANGES BETWEEN 2.3.6 and 2.3.5
I. IMPORTANT BUG FIXES
- A bunch of potential security problems have been found. All
users should update.
- Microsoft Unicode cmaps in TrueType fonts are now always
preferred over Apple cmaps. This is not a bug per se, but there
exist some buggy fonts created for MS which have broken Apple
cmaps. This affects only the automatic selection of FreeType;
it's always possible to manually select an Apple Unicode cmap if
desired.
- Many bug fixes to the TrueType bytecode interpreter.
- Improved Mac support.
- Subsetted CID-keyed CFFs are now supported correctly.
- CID-keyed CFFs with subfonts which are scaled in a non-standard
way are now handled correctly.
- A call to FT_Open_Face with `face_index' < 0 crashed FreeType if
the font was a Windows (bitmap) FNT/FON.
II. IMPORTANT CHANGES
- The new function `FT_Get_CID_Registry_Ordering_Supplement' gives
access to those fields in a CID-keyed font. The code has been
contributed by Derek Clegg.
- George Williams contributed code to validate the new `MATH'
OpenType table (within the `otvalid' module). The `ftvalid'
demo program has been extended accordingly.
- An API for cmap 14 support (for Unicode Variant Selectors, UVS)
has been contributed by George Williams.
- A new face flag FT_FACE_FLAG_CID_KEYED has been added, together
with a macro FT_IS_CID_KEYED which evaluates to 1 if the font is
CID-keyed.
III. MISCELLANEOUS
- Build support for symbian has been contributed.
- Better WGL4 glyph name support, contributed by Sergey Tolstov.
- Debugging output of the various FT_TRACEX macros is now sent to
stderr.
- The `ftview' demo program now provides artificial slanting too.
- The `ftvalid' demo program has a new option `-f' to select the
font index.

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

* 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.

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.

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.
* include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
FT_IS_CID_KEYED): New macros.
* src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
maximum CID value in CID-keyed CFFs.
Handle FT_FACE_FLAG_CID_KEYED flag.
* docs/CHANGES: Document it.
Fix CFF font matrix calculation and improve precision.
* src/cff/cffparse.c (cff_parse_real): Increase precision if integer
part is zero.
(cff_parse_font_matrix): Simplify computation of `units_per_em';
this prevents overflow also.
Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
* 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>
Adjustments for Visual C++ 8.0, as reported by Rainer Deyke.
* builds/compiler/visualc.mk (CFLAGS): Remove /W5.
(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().

* 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.

* 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.

Update documentation accordingly.
* src/sfnt/ttcmap.c: Stronger cmap 14 validation.
Make the code a little more consistent with FreeType coding

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.
