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

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.

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.
2010-01-05 Werner Lemberg <wl@gnu.org>

* src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
`offset_i' and `length_i'.
2010-01-05 Ralph Giles <giles@ghostscript.com>
Enable the incremental font interface by default.
Ghostscript requires the incremental font interface for handling
some Postscript documents. It is moving to using FreeType as its
primary renderer; supporting this in the default build makes it
Ghostscript to be linked against the system FreeType when one is
available.
* include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
Uncomment.
2010-01-05 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #28395.
* src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c

This fixes Savannah bug #28480.
* src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
if incremental interface is used.
2010-01-04 Ken Sharp <ken.sharp@artifex.com>
Make incremental interface work with TrueType fonts.
This fixes Savannah bug #28478.
* src/truetype/ttgload.c (load_truetype_glyph): Don't check
`glyf_offset' if incremental interface is used.
2009-12-31 Lars Abrahamsson <wonko@opera.com>
Make compilation with FT_CONFIG_OPTION_PIC work again.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.
* src/base/ftinit.c (ft_destroy_default_module_classes,

compilation).
* src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.
2009-12-22 Marc Kleine-Budde <mkl@pengutronix.de>

* builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
appropriate.
2009-12-20 Werner Lemberg <wl@gnu.org>
Fix compiler warning.
Reported by Sean.
* src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
source files; however, some compilers warn about an unused variable
declaration. This is now replaced with a typedef.
2009-12-18 Werner Lemberg <wl@gnu.org>
Fix Savannah bug #28320.
There exist corrupt, subsetted fonts (embedded in PDF files) which
contain a private dict that ends with an unterminated floating point
number (no operator following). We now ignore this error (as
acrobat does).
* src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
unterminated floating point numbers.
2009-12-16 Werner Lemberg <wl@gnu.org>

2009-12-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
The linker of Mac OS X 10.6 is sensitive to the architecture. If
the architectures are specified explicitly for the C compiler, the
linker requires the architecture specifications too.
* builds/unix/configure.raw: Replace `-isysroot' option parser by
more generic argument parser.
2009-12-15 Werner Lemberg <wl@gnu.org>
Fix compiler warnings.
Reported by Sean.
* src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data
type.
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.
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<op_setcurrentpoint>: Comment out code.
2009-12-14 Bram Tassyns <bramt@enfocus.be>
Fix parsing of /CIDFontVersion.
This fixes Savannah bug #28287.
* src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in

2009-09-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[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.

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.

its component x, y are typed as FT_Long, but
their sources are always FT_Int16 when they are

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

`delta', they are explicitly cast 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.

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.

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):

(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.

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.

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.)
Patch from Savannah bug #25133.

2008-12-10 Werner Lemberg <wl@gnu.org>
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.
* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
New macros.
* src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
semantics as described above.
* src/truetype/ttobjs.c (tt_check_trickyness): New function, using
code of ...
(tt_face_init): This function, now simplified and updated to new
semantics.

fonts.
* docs/CHANGES: Document it.

* include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value
0x100 instead of 0x10000; the latter value is already occupied by

* 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>

(open_face_from_buffer): Removed. Use the implementation in
ftobjs.c.
(ft_lookup_PS_in_sfnt): Ditto.
* builds/mac/FreeType.m68k_far.make.txt: Build ftmac.c as an
included part of ftbase.c, to share the functions in ftobjs.c. The
rule compiling ftmac.c separately is removed and the rule copying
ftbase.c from src/base/ftbase.c to builds/mac/ftbase.c is added.
* builds/mac/FreeType.m68k_cfm.make.txt: Ditto.
* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
2008-10-02 Bram Tassyns <bramt@enfocus.be>
* src/cff/cffgload.c (cff_slot_load): Map CID 0 to GID 0. This
fixes Savannah bug #24430.
2008-10-02 Werner Lemberg <wl@gnu.org>
* builds/freetype.mk (BASE_H): Rename to...
(INTERNAL_H): This.
(FREETYPE_H): Updated.
* src/base/rules.mk: (BASE_OBJ_S, OBJ_DIR/%.$O): Add BASE_H.
* src/bdf/rules.mk (BDF_DRV_H): Add bdferror.h.
* src/cache/rules.mk (CACHE_DRV_H): Add ftccache.h and ftcsbits.h.
* src/pcf/rules.mk (PCF_DRV_H): Add pcfread.h.
* src/raster/rules.mk (RASTER_DRV_H): Add ftmisc.h.
* src/type42/rules.mk (T42_DRV_H): Add t42types.h.
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
slightly different between Carbon-dependent parser and Carbon-free
parser. They are merged with the platform-specific conditional.
(ft_lookup_PS_in_sfnt): Ditto.
* src/base/ftmac.c: Include ftbase.h.
(memory_stream_close): Removed.
(new_memory_stream): Ditto.
(open_face_from_buffer): Removed. Use the implementation in
ftobjs.c.
(ft_lookup_PS_in_sfnt): Ditto.
2008-10-02 Werner Lemberg <wl@gnu.org>
* src/sfnt/sfobjs.c (sfnt_load_face): `psnames_error' is only needed
if TT_CONFIG_OPTION_POSTSCRIPT_NAMES is defined.
2008-10-01 Werner Lemberg <wl@gnu.org>
* src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c
(cff_face_done), src/pfr/pfrobjs.c (pfr_face_done),
src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c
(cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done),
src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0.
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
include ftmac.c source into ftbase.c.
2008-09-22 Werner Lemberg <wl@gnu.org>
* src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
cff_decoder_parse_charstrings): Handle (invalid)
`callothersubr' and `pop' instructions.
2008-09-22 John Tytgat <John.Tytgat@esko.com>
Fix Savannah bug #24307.
* include/freetype/internal/t1types.h (CID_FaceRec),
src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.
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>.
2008-09-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* src/otvalid/Jamfile: Add missing target `otvmath' for multi build
by jam.
* src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
jam.
2008-09-20 Werner Lemberg <wl@gnu.org>
* src/smooth/ftgrays.c (gray_find_cell): Fix threshold. The values
passed to this function are already `normalized'. Problem reported
by Stephan T. Lavavej <stl@nuwen.net>.
* docs/CHANGES: Document it.
2008-09-20 Werner Lemberg <wl@gnu.org>
* src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
(FT_Outline_Decompose): Decorate with tracing messages.
* src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
FT_DEBUG_LEVEL_TRACE.
[_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
stdarg.h.
(FT_TRACE) [_STANDALONE_]: Remove.
(FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
(FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.
(FT_ERROR) [_STANDALONE_]: Updated.
(gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
Use FT_TRACE7.
(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>
* src/base/ftmac.c: Import sfnt-wrapped Type1 and sfnt-wrapped
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.
(ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '
table in sfnt table directory. It is used before loading TrueType
font driver.
* docs/CHANGES: Add note about the current status of sfnt-wrapped
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.
2008-09-15 George Williams <gww@silcom.com>
Fix Savannah bug #24179, reported by Bram Tassyns.
* src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
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.
* devel/ftoption.h: Synchronize with
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'.
[!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
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.
* src/cff/cffgload.c (cff_decoder_set_width_only): New function.
(cff_decoder_parse_charstrings): Handle `width_only'.
(cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.
* src/cff/cffgload.h (cff_decoder): New element `width_only'.
(cff_decoder_set_width_only): New declaration.
* src/truetype/ttdriver.c (tt_get_advances): New function.
(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.
* src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.
Add checks for minimum version of the `autotools' stuff.
* autogen.sh: Implement it.
(get_major_version, get_minor_version, get_patch_version,
compare_to_minimum_version, check_tool_version): New auxiliary
functions.
* README.CVS: Document it.
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.
* src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
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.
(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.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.
