[cache] Fix Savannah bug #27441, clean up Redhat bugzilla #513582.
Tricky casts in FTC_{CACHE,GCACHE,MRULIST}_LOOKUP_CMP() are removed.
Now these functions should be called with FTC_Node or FTC_MruNode
variable, and the caller should cast them to appropriate pointers to
concrete data. These tricky casts can GCC-4.4 optimizer (-O2)
confused and the crashing binaries are generated.
* src/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Drop tricky cast.
Now the 4th argument `node' of this function should be typed as
FTC_MruNode.
* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): For inline
implementation, new temporal variable FTC_MruNode `_mrunode' to take
the pointer from FTC_MRULIST_LOOKUP_CMP(). For non-inline
implementation, tricky cast is dropped.
* src/cache/ftcmanag.c (FTC_SIZE_NODE): New macro casting
to FTC_SizeNode.
(FTC_Manager_LookupSize): Replace FTC_SizeNode `node' by FTC_MruNode
`mrunode', and FTC_SIZE_NODE() is inserted.

(FTC_Manager_LookupFace) Replace FTC_FaceNode `node' by FTC_MruNode
`mrunode', and FTC_FACE_NODE() is inserted.
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Change the type of
`node' from FTC_INode to FTC_Node. Extra casting macro FTC_NODE()
is dropped.
(FTC_ImageCache_LookupScaler): Ditto.
(FTC_SBitCache_Lookup): Change the type of `node' from FTC_SNode to
FTC_Node. Extra casting macro FTC_NODE() is dropped. FTC_SNODE()
is inserted.
(FTC_SBitCache_LookupScaler): Ditto.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the type of
`node' from FTC_CMapNode to FTC_Node. Extra casting macro
FTC_NODE() is dropped, FTC_CMAP_NODE() is inserted.

[BDF] Modify hash API to take size_t value instead of void *.
The hash API in BDF driver is designed to be generic, it takes
void * typed data. But BDF driver always gives an unsigned long
integer (the index to a property). To reduce non-essential
casts from unsigned long to void* and from void* to unsigned
long, the hash API is changed to take size_t integer.
The issue of incompatible cast between unsigned long and void*
on LLP64 platform is reported by NightStrike from MinGW-Win64
project. See
http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
* src/bdf/bdf.h: The type of hashnode->data is changed from
void* to size_t.
* src/bdf/bdflib.c (hash_insert): Get size_t data, instead of
void* data.
(bdf_create_property): Get the name length of new property by
size_t variable, with a cut-off at FT_ULONG_MAX.
(_bdf_set_default_spacing): Get the name length of the face by
size_t variable, with a cut-off at 256.
(bdf_get_property): Get the property id by size_t variable to
reduce the casts between 32-bit prop ID & hashnode->data during
simple copying.
(_bdf_add_property): Ditto.
(_bdf_parse_start): Calculate the index to the property array
by size_t variable.
(bdf_get_font_property): Drop a cast to unsigned long.

[Win64] Improve the computation of random seed from stack address.
On LLP64 platform, the conversion from pointer to FT_Fixed need
to drop higher 32-bit. Explict casts are required. Reported by
NightStrike from MinGW-w64 project. See
http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
* src/cff/cffgload.c: Convert the pointers to FT_Fixed explicitly.

Improve vertical metrics calculation (Savannah bug #27364).
The calculation of `vertBearingX' is not defined in the OTF font
spec so FreeType does a `best effort' attempt. However, this value
is defined in the PDF and PostScript specs, and that algorithm is
better than the one FreeType currently uses:
FreeType: Use the middle of the bounding box as the X coordinate
of the vertical origin.
Adobe PDF spec: Use the middle of the horizontal advance vector as
the X coordinate of the vertical origin.
FreeType's algorithm goes wrong if you have a really small glyph
(like the full-width, circle-like dot at the end of the sentence, as
used in CJK scripts) with large bearings. With the FreeType
algorithm this dot gets centered on the baseline; with the PDF
algorithm it gets the correct location (in the top right). Note
that this is a serious issue, it's like printing the dot at the end
of a Roman sentence at the center of the textline instead of on the
baseline like it should. So i believe the PDF spec's algorithm
should be used in FreeType as well.
The `vertBearingY' value for such small glyphs is also very strange
if no `vmtx' information is present, since the height of the bbox is
not representable for the height of the glyph visually (the
whitespace up to the baseline is part of the glyph). The fix also
includes some code for a better estimate of `vertBearingY'.
* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
is now calculated as described by the Adobe PDF Spec. Estimate for
`vertBearingY' now works better for small glyphs completely above or
below the baseline into account.
* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
calculated as described by the Adobe PDF Spec. Vertical metrics
information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
was not defined.
* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
now calculated as described by the Adobe PDF Spec.
2009-09-01 John Tytgat <John.Tytgat@esko.com>

* src/truetype/ttgload.c (load_truetype_glyph):
Insert cast from FT_Long (deltas[i].{x,y}) to
FT_Int16 in the summation of deltas[] for composite
glyphs. Because deltas[i] is typed as FT_Pos,
its component x, y are typed as FT_Long, but
their sources are always FT_Int16 when they are
loaded by ft_var_readpackeddeltas(). However,
the limitation about the summed deltas is unclear.

* include/freetype/internal/tttypes.h: The type
of TT_BDF->string_size is extended from FT_UInt32
to FT_ULong, because BDF specification does not
restrict the length of string.
* src/sfnt/ttbdf.c: The scratch variable `strings'
to load TT_BDF->string_size is matched with
TT_BDF->string_size.
2009-07-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

is changed to size_t, for similarity with ANSI C
string functions.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load): The type of
`bytes' is changed to FT_Offset, because it is passed
to FT_ALLOC(), via ft_glyphslot_alloc_bitmap(). At

gray_set_cell(). The type of TCell->x is extended
to `TPos', because gray_find_cell() sets it by
TWorker.ex. The type of TCell->cover is extended
to `TCoord', because gray_render_scanline() adds
TCoord value to it. The type of TWork.cover is matched
with TCell->cover. The types of

is updated by the differential values including
`delta', they are explicitly casted to TArea, because
the type of `delta' is not TArea but TCoord.
(gray_render_line): The type of `mod' is extended
from int to TCoord, because (TCoord)dy is added to mod.

* src/autofit/aflatin.c (af_latin_hint_edges):
Ditto.
* src/autofit/aftypes.h: In AF_ScriptClassRec,
the size of metric `script_metrics_size' should
be counted by FT_Offset variable instead of FT_UInt.

(af_glyph_hints_align_strong_points): The cursors
for the edges `min', `max', `mid' in the memory
buffer should be typed FT_PtrDist.

the check for too large glyph. Replace the pair of `pitch' and
`height' by the pair of `width' and `height'. `pitch' cannot

Use 16.16 format while parsing Type 1 charstrings.
This fixes Savannah bug #26867.
Previously, only integers have been used which can lead to serious
rounding errors.
However, fractional values are only used internally; after the
charstrings (of either Type 1 or 2) have been processed, the
resulting coordinates get rounded to integers currently -- before
applying scaling. This should be fixed; at the same time a new load
flag should be introduced, to be used in combination with
FT_LOAD_NO_SCALE, which indicates that font units are returned in
16.16 format. Similarly, the incremental interface should be
extended to allow fractional values for metrics.
* include/freetype/internal/psaux.h (T1_BuilderRec): Remove `shift'
field.

2009-06-18 Werner Lemberg <wl@gnu.org>
Fix B/W rasterization of subglyphs with different drop-out modes.
Normally, the SCANMODE instruction (if present) to set the drop-out
mode in a TrueType font is located in the `prep' table only and thus
valid for all glyphs. However, there are fonts like `pala.ttf'
which additionally contain this instruction in the hinting code of
some glyphs (but not all). As a result it can happen that a
composite glyph needs multiple drop-out modes for its subglyphs
since the rendering state gets reset for each subglyph.
FreeType collects the hinted outlines from all subglyphs, then it
sends the data to the rasterizer. It also sends the drop-out mode
-- after hinting has been applied -- and here is the error: It sends
the drop-out mode of the last subglyph only; drop-out modes of all
other subglyphs are lost.
This patch fixes the problem; it adds a second, alternative
mechanism to pass the drop-out mode: For each contour, the
rasterizer now checks the first `tags' array element. If bit 2 is
set, bits 5-7 contain the contour's drop-out mode, overriding the
global drop-out mode.
* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
`tags[0]'.
* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
Use bits 3-5 instead of 0-2.
(New_Profile): Set the drop-out mode in the profile's `flags' field.
(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
necessary.
(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
mode.
2009-06-16 Werner Lemberg <wl@gnu.org>
Improve scan conversion rules 4 and 6.
Two new constraints are introduced to better identify a `stub' -- a
concept which is only vaguely described in the OpenType
specification. The old code was too rigorous and suppressed more
pixel than it should.
. The intersection of the two profiles with the scanline is less
than a half pixel. Code related to this was already present in
the sources but has been commented out.
. The endpoint of the original contour forming a profile has a
distance (`overshoot') less than half a pixel to the scanline.
Note that the two additional conditions fix almost all differences
to the Windows rasterizer, but some problematic cases remain.
* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
macros for the `flags' field in the `TProfile' structure.
(IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
(New_Profile, End_Profile): Pass overshoot flag as an argument and
set it accordingly.
Update callers.
(Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
constraints.
2009-06-11 Werner Lemberg <wl@gnu.org>
Increase precision for B/W rasterizer.
* src/raster/ftraster.c (Set_High_Precision): Add two more bits to

on my GNU/Linux box I don't see a performance degradation.

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

2009-03-02 Alexey Kryukov <anagnost@yandex.ru>
Fix handling of EBDT formats 8 and 9.
The main cycle in `blit_sbit' makes too many iterations: it actually
needs the count of lines in the source bitmap rather than in the
target image.

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.)

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.

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.

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

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>

fixes Savannah bug #24430.
2008-10-02 Werner Lemberg <wl@gnu.org>
* builds/freetype.mk (BASE_H): Rename to...
(INTERNAL_H): This.

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

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
function for MPW building. It is synchronized the condition to

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>.

(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.

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.

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.

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'.

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.

(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.

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 Savannah 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.

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.

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.

`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.

(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

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.

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/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'.

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>

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,

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>

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'.

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.

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
<CoreServices/CoreServices.h> and
<ApplicationServices/ApplicationServices.h> instead of
all-in-one header file <Carbon/Carbon.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,

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.

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'.

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.

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

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

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'

(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'.

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.

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.

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

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).

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.

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.

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

LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
isn't defined at compile time. This only changes the content of the

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.

2006-06-08 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

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'

Renamed to ...
(PS_GetGlyphNameFunc): This.

* 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

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%.

(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/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.
