* include/freetype/freetype.h (FREETYPE_PATCH): Set to 12.
* builds/unix/configure.raw (version_info): Set to 10:0:4.
2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Improve autotool version checking to work with beta releases.
* autogen.sh (check_tool_version): Improve the extraction of version
number from "tool --version" output. Some beta releases of
autotools have extra strings before version number.
2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix overallocating bug in FT_Outline_New_Internal().
* src/base/ftoutln.c (FT_Outline_New_Internal): The length of
FT_Outline->points[] should be numPoints, not 2 * numPoints.
Found by Paul Messmer, see
https://lists.gnu.org/archive/html/freetype-devel/2010-02/msg00003.html
2010-02-10 Ken Sharp <ken.sharp@artifex.com>
Really fix Savannah bug #28678 (part 2).
Since we consider `sbw' for the horizontal direction only, we still have
to synthesize vertical metrics if the user wants to use the vertical
writing direction.
* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
set.
2010-02-10 Ken Sharp <ken.sharp@artifex.com>
Really fix Savannah bug #28678 (part 1).
After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only. For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction. Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).
* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.
* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
(cff_slot_load), src/type1/t1gload.c
(T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
(cid_load_glyph): Use it.
2010-02-08 Werner Lemberg <wl@gnu.org>
* devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define.
2010-02-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Prevent NULL pointer dereference passed to FT_Module_Requester.
* src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'.
* src/psnames/psmodule.c (psnames_get_interface): Ditto.
* src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'.
* src/truetype/ttdriver.c (tt_get_interface): Ditto.
2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix memory leaks in previous patch.
* src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings
allocated for face->root.family_name and style_name.
2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
New parameters for FT_Open_Face() to ignore preferred family names.
Preferred family names should be used for legacy systems that
can hold only a few faces (<= 4) for a family name. Suggested by
Andreas Heinrich.
https://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html
* include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define.
* src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and
ignore preferred family and subfamily names if requested.
2010-01-27 Ken Sharp <ken.sharp@artifex.com>
Fix Savannah bug #28678.
* src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
(cid_load_glyph): Handle vertical metrics correctly.
* src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle
vertical metrics correctly.
(T1_Load_Glyph): Don't synthesize vertical metrics.
2010-01-14 Werner Lemberg <wl@gnu.org>
Make FT_Set_Transform work if no renderer is available.
* src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation
if no renderer is compiled into the library.
2010-01-14 Werner Lemberg <wl@gnu.org>
Fix compilation warning.
* src/base/ftbase.h: s/LOCAL_DEF/LOCAL/.
* src/base/ftobjs.c: Include ftbase.h conditionally.
2010-01-11 Kwang Yul Seo <skyul@company100.net>
Provide inline assembly code for RVCT compiler.
This is Savannah patch #7059.
* include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.
2010-01-08 Ken Sharp <ken.sharp@artifex.com>
Fix Savannah bug #28521.
Issue #28226 involved a work-around for a font which used the
`setcurrentpoint' operator in an invalid way; this operator is only
supposed to be used with the result of OtherSubrs, and the font used
it directly. The supplied patch removed the block of code which
checked this usage entirely.
This turns out to be a Bad Thing. If `setcurrentpoint' is being
used correctly it should reset the flex flag in the decoder. If we
don't do this then the flag never gets reset and we omit any further
contours from the glyph (at least until we close the path or
similar).
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<op_setcurrentpoint>: Handle `flex_state' correctly.

Enable the incremental font interface by default.

2009-12-14 Ken Sharp <ken.sharp@artifex.com>
Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
This fixes Savannah bug #28226.
At least two wild PostScript files of unknown provenance contain
Type 1 fonts, apparently converted from TrueType fonts in earlier
PDF versions of the files, which use the `setcurrentpoint' operator
inappropriately.
FreeType currently throws an error in this case, but Ghostscript and
Adobe Distiller both accept the fonts and ignore the problem. This
commit #ifdefs out the check so PostScript interpreters using
FreeType can render these files.
The specification says `setcurrentpoint' should only be used to set
the point after a `Subr' call, but these fonts use it to set the
initial point to (0,0). Unnecessarily so, as they correctly use an
`hsbw' operation which implicitly sets the initial point.

[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
https://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

2009-09-02 Bram Tassyns <bramt@enfocus.be>
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.

* src/cff/cffload.c (cff_charset_load): Type large
constants > 0x7FFF as long, because normal constants
are typed signed integer that is less than 0x8000 on
16-bit systems.

cache: Check higher bits in flags for non ILP32 systems.
4 public functions ought to take FT_ULong flags, but take
FT_UInt flags. To keep binary compatibility, we drop higher
bits on non ILP32 platforms,
ILP64 systems: No drop occurs.
LP64 systems: Higher bits are not used.
16-bit systems: Drop can occur.
See
https://lists.gnu.org/archive/html/freetype-devel/2008-12/msg00065.html
These functions will be refined to take FT_ULong flags in
next bump with incompatible API change.
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup):
Check `flags' in `type', the 2nd argument.
(FTC_SBitCache_Lookup): Ditto.
(FTC_ImageCache_LookupScaler): Check `load_flags',
the 3rd argument.
(FTC_SBitCache_LookupScaler): Ditto.
