Really fix Savannah bug #28678 (part 1).
65
After long discussion, we now consider the character width vector
66
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
67
direction only. For example, if you are using the horizontal
68
writing direction, you get the horizontal and vertical components of
69
the advance width for this direction. Note that OpenType and CFF fonts
70
don't have such a vertical component; instead, the GPOS table can be
71
used to generate two-dimensional advance widths (but this isn't

2010-01-08 Ken Sharp <ken.sharp@artifex.com>
154
Fix Savannah bug #28521.
156
Issue #28226 involved a work-around for a font which used the
157
`setcurrentpoint' operator in an invalid way; this operator is only
158
supposed to be used with the result of OtherSubrs, and the font used
159
it directly. The supplied patch removed the block of code which
160
checked this usage entirely.
162
This turns out to be a Bad Thing. If `setcurrentpoint' is being
163
used correctly it should reset the flex flag in the decoder. If we
164
don't do this then the flag never gets reset and we omit any further
165
contours from the glyph (at least until we close the path or

Enable the incremental font interface by default.
186
Ghostscript requires the incremental font interface for handling
187
some Postscript documents. It is moving to using FreeType as its
188
primary renderer; supporting this in the default build makes it

289
Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
290
This fixes Savannah bug #28226.
292
At least two wild PostScript files of unknown provenance contain
293
Type 1 fonts, apparently converted from TrueType fonts in earlier
294
PDF versions of the files, which use the `setcurrentpoint' operator
297
FreeType currently throws an error in this case, but Ghostscript and
298
Adobe Distiller both accept the fonts and ignore the problem. This
299
commit #ifdefs out the check so PostScript interpreters using
300
FreeType can render these files.
302
The specification says `setcurrentpoint' should only be used to set
303
the point after a `Subr' call, but these fonts use it to set the
304
initial point to (0,0). Unnecessarily so, as they correctly use an
305
`hsbw' operation which implicitly sets the initial point.

[BDF] Modify hash API to take size_t value instead of void *.
626
The hash API in BDF driver is designed to be generic, it takes
627
void * typed data. But BDF driver always gives an unsigned long
628
integer (the index to a property). To reduce non-essential
629
casts from unsigned long to void* and from void* to unsigned
630
long, the hash API is changed to take size_t integer.
631
The issue of incompatible cast between unsigned long and void*
632

Improve vertical metrics calculation (Savannah bug #27364).
681
The calculation of `vertBearingX' is not defined in the OTF font
682
spec so FreeType does a `best effort' attempt. However, this value
683
is defined in the PDF and PostScript specs, and that algorithm is
684
better than the one FreeType currently uses:
686
FreeType: Use the middle of the bounding box as the X coordinate
687
of the vertical origin.
689
Adobe PDF spec: Use the middle of the horizontal advance vector as
690
the X coordinate of the vertical origin.
692
FreeType's algorithm goes wrong if you have a really small glyph
693
(like the full-width, circle-like dot at the end of the sentence, as
694
used in CJK scripts) with large bearings. With the FreeType
695
algorithm this dot gets centered on the baseline; with the PDF
696
algorithm it gets the correct location (in the top right). Note
697
that this is a serious issue, it's like printing the dot at the end
698
of a Roman sentence at the center of the textline instead of on the
699
baseline like it should. So i believe the PDF spec's algorithm
700
should be used in FreeType as well.
702
The `vertBearingY' value for such small glyphs is also very strange
703
if no `vmtx' information is present, since the height of the bbox is
704
not representable for the height of the glyph visually (the
705
whitespace up to the baseline is part of the glyph). The fix also
706
includes some code for a better estimate of `vertBearingY'.
708
* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
709
is now calculated as described by the Adobe PDF Spec. Estimate for
710
`vertBearingY' now works better for small glyphs completely above or
711
below the baseline into account.
713
* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
714
calculated as described by the Adobe PDF Spec. Vertical metrics
715
information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
718
* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
719
now calculated as described by the Adobe PDF Spec.

TWorker.ex. The type of TCell->cover is extended
1244
to `TCoord', because gray_render_scanline() adds
1245
TCoord value to it. The type of TWork.cover is matched

`delta', they are explicitly cast to TArea, because
1258
the type of `delta' is not TArea but TCoord.
1259
(gray_render_line): The type of `mod' is extended
1260
from int to TCoord, because (TCoord)dy is added to mod.

the internal calculation from FT_Int to FT_Long, to
1357
avoid an overflow on 16-bit platforms. The caller of
1358
this function should use only the sign of result,

avoid integer overflow on 16-bit platform, too large
1369
glyph index should be excluded.
1370
(BDF_Glyph_Load): The glyph pitch in FT2 is typed as

1377
pitch in FT2 is typed as FT_UInt, although PFR font
1378
format can include huge bitmap glyph with 24-bit pitch
1379
(however, a glyph spends 16.7 pixel, it's not realistic).

Use 16.16 format while parsing Type 1 charstrings.
2100
This fixes Savannah bug #26867.
2102
Previously, only integers have been used which can lead to serious
2105
However, fractional values are only used internally; after the
2106
charstrings (of either Type 1 or 2) have been processed, the
2107
resulting coordinates get rounded to integers currently -- before
2108
applying scaling. This should be fixed; at the same time a new load
2109
flag should be introduced, to be used in combination with
2110
FT_LOAD_NO_SCALE, which indicates that font units are returned in
2111
16.16 format. Similarly, the incremental interface should be
2112
extended to allow fractional values for metrics.

2217
Fix B/W rasterization of subglyphs with different drop-out modes.
2219
Normally, the SCANMODE instruction (if present) to set the drop-out
2220
mode in a TrueType font is located in the `prep' table only and thus
2221
valid for all glyphs. However, there are fonts like `pala.ttf'
2222
which additionally contain this instruction in the hinting code of
2223
some glyphs (but not all). As a result it can happen that a
2224
composite glyph needs multiple drop-out modes for its subglyphs
2225
since the rendering state gets reset for each subglyph.
2227
FreeType collects the hinted outlines from all subglyphs, then it
2228
sends the data to the rasterizer. It also sends the drop-out mode
2229
-- after hinting has been applied -- and here is the error: It sends
2230
the drop-out mode of the last subglyph only; drop-out modes of all
2231
other subglyphs are lost.
2233
This patch fixes the problem; it adds a second, alternative
2234
mechanism to pass the drop-out mode: For each contour, the
2235
rasterizer now checks the first `tags' array element. If bit 2 is
2236
set, bits 5-7 contain the contour's drop-out mode, overriding the
2237
global drop-out mode.
2239
* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
2241
* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in

2255
Improve scan conversion rules 4 and 6.
2257
Two new constraints are introduced to better identify a `stub' -- a
2258
concept which is only vaguely described in the OpenType
2259
specification. The old code was too rigorous and suppressed more
2260
pixel than it should.
2262
. The intersection of the two profiles with the scanline is less
2263
than a half pixel. Code related to this was already present in
2264
the sources but has been commented out.
2266
. The endpoint of the original contour forming a profile has a
2267
distance (`overshoot') less than half a pixel to the scanline.
2269
Note that the two additional conditions fix almost all differences
2270
to the Windows rasterizer, but some problematic cases remain.
2272
* src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New

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

3130
2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
3132
Fix handling of EBDT formats 8 and 9 (part 2).
3134
This patch fixes the following problems in ttsbit0.c:
3136
. Bitmaps for compound glyphs were never allocated.
3138
. `SBitDecoder' refused to load metrics if some other metrics have
3139
already been loaded. This condition certainly makes no sense for
3140
recursive calls, so I've just disabled it. Another possibility
3141
would be resetting `decoder->metrics_loaded' to false before
3142
loading each composite component. However, we must restore the
3143
original metrics after finishing the recursion; otherwise we can
3144
get a misaligned glyph.
3146
. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
3147
causing some glyph components to be shifted too far to the right
3148
(especially noticeable for small sizes).
3150
Note that support for grayscale bitmaps (not necessarily compound) is
3151
completely broken in ttsbit0.c.
3153
* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
3154
(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
3156

FT_USE_MODULE declares things as:
3537
extern const FT_Module_Class
3539
(or similar for C++). However, the actual types of the variables
3540
being declared are often different, e.g., FT_Driver_ClassRec or
3541
FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
3543
This works with most C compilers (since those structs begin with an
3544
FT_Module_Class struct), but technically it's undefined behavior.
3546
To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
3549
All declarations that refer to the same object or function shall
3550
have compatible type; otherwise, the behavior is undefined.
3552
(And they are not compatible types.)
3554
Most C compilers don't reject (or even detect!) code which has this
3555
issue, but the GCC LTO development branch compiler does. (It
3556
outputs the types of the objects while generating .o files, along
3557
with a bunch of other information, then compares them when doing the
3558
final link-time code generation pass.)

2008-12-10 Werner Lemberg <wl@gnu.org>
3614
Generalize the concept of `tricky' fonts by introducing
3615
FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
3616
engine is necessary for correct rendering.
3618
At the same time, slightly modify the behaviour of tricky fonts:
3619
FT_LOAD_NO_HINTING is now ignored. To really force raw loading
3620
of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
3621
FT_LOAD_NO_AUTOHINT must be used.
3623
Finally, tricky TrueType fonts always use the bytecode interpreter
3624
even if the patented code is used.
3626
* include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
3629

semantics as described above.

Really fix Savannah bug #25010: An SFNT font with neither outlines
3645
nor bitmaps can be considered as containing space `glyphs' only.
3647

3648
a `glyf' table is missing.
3650
* src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
3651
`glyf' table but a non-zero `loca' entry.

3949
* src/base/ftbase.h: New file to declare the private utility
3950
functions shared by the sources of base modules. Currently,
3951
`ft_lookup_PS_in_sfnt' and `open_face_from_buffer' are declared to
3952
share between ftobjs.c and ftmac.c.
3954
* src/base/rule.mk: Add ftbase.h.
3956
* src/base/ftobjs.c: Include ftbase.h.
3957
(memory_stream_close): Build on any platform when old MacOS font
3959
(new_memory_stream): Ditto.
3960
(open_face_from_buffer): Build on any platform when old MacOS font
3961
support is enabled. The counting of the face in a font file is
3962
slightly different between Carbon-dependent parser and Carbon-free
3963
parser. They are merged with the platform-specific conditional.
3964
(ft_lookup_PS_in_sfnt): Ditto.
3966
* src/base/ftmac.c: Include ftbase.h.
3967
(memory_stream_close): Removed.

3989
* src/base/rules.mk: Add conditional source to BASE_SRC, for `make
3990
multi' on Mac OS X. If the macro $(ftmac_c) is defined,
3991
$(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the
3992
lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
3994
* builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
3995
* builds/unix/configure.raw: Add procedure to set up appropriate
3996

2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4076
* src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
4077
sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
4078
`open_face_from_buffer' frees the passed buffer if it cannot open a
4079
face from the buffer, so the caller must not free it.

4092
2008-09-18 Werner Lemberg <wl@gnu.org>
4094
* src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
4095
orthogonality (ft_free and ft_sfree could belong to different memory
4096
pools). This fixes Savannah bug #24297.
4098
2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4100
* src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined

4115
2008-09-15 Werner Lemberg <wl@gnu.org>
4117
* src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
4118
and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
4119
prevent unconditional definition. This fixes Savannah bug #24241.
4121
* src/psnames/pstables.h: Regenerated.

2008-09-13 Werner Lemberg <wl@gnu.org>
4125

2008-09-11 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4142
* builds/unix/ftconfig.in: Duplicate the cpp computation of
4143
FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
4144
(FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp
4145
computation is disabled and the statically configured sizes are
4146
used. This fixes Savannah bug #21250.
4148
* builds/unix/configure.raw: Add the checks to compare the cpp
4149
computation results of the bit length of int and long versus the
4150
sizes detected by running `configure'. If the results are
4151
different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
4153
New option --{enable|disable}-biarch-config is added to define or
4154
undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
4156
2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4158
* builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
4159
ApplicationService framework is missing. Although this value is not
4160
used in building of FreeType2, it is written in `freetype2.pc' and
4163
2008-09-01 david turner <david@freetype.org>
4165
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
4166
index to mean `use default cached FT_Face's charmap'. This fixes
4167
Savannah bug #22625.
4168
* include/freetype/ftcache.h: Document it.
4171
Make FT_MulFix an inlined function. This is done to speed up
4172
FreeType a little (on x86 3% when loading+hinting, 10% when
4173
rendering, ARM savings are more important though). Disable this by
4174
undefining FT_CONFIG_OPTION_INLINE_MULFIX.
4176
Use of assembler code can now be controlled with
4177
FT_CONFIG_OPTION_NO_ASSEMBLER.

4195
* src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
4199
Add a new header named FT_ADVANCES_H declaring some new APIs to
4200
extract the advances of one or more glyphs without necessarily
4201
loading their outlines. Also provide `fast loaders' for the
4202
TrueType, Type1, and CFF font drivers (more to come later).

2008-08-28 Werner Lemberg <wl@gnu.org>
4255

2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4267
* src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
4268
even if passed library or arguments are invalid. This fixes a bug
4269
that an uninitialized stream is freed when an invalid library handle
4270
is passed. Originally proposed by Mike Fabian, 2008/08/18 on
4272
(FT_Open_Face): Ditto (stream).
4273
(load_face_in_embedded_rfork): Ditto (stream2).
4275
2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4277
* src/base/ftmac.c: Add a fallback to guess the availability of the
4278
`ResourceIndex' type. It is used when built without configure
4279
(e.g., a build with Jam).
4280
* builds/mac/ftmac.c: Ditto.
4281
* builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
4282
explicitly, even if `ResourceIndex' is unavailable.
4284
2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4286
* builds/unix/configure.raw: In checking of Mac OS X features,
4287
all-in-one header file `Carbon.h' is replaced by the minimum
4288
header file `CoreServices.h', similar to current src/base/ftmac.c.
4290
2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4292
* src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
4293
sub-header when its code_count is 0. Many Japanese Dynalab fonts
4294
include such an empty sub-header (code_count == 0, first_code == 0
4295
delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
4297
2008-08-04 Werner Lemberg <wl@gnu.org>
4299
* src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
4300
Savannah bug #23995.
4302
* src/cid/cidload.c (parse_expansion_factor): New callback function.
4303
(cid_field_records): Use it for `ExpansionFactor'.
4304
* src/cod/cidtoken.h: Handle `ForceBold' keyword.
4305
Don't handle `ExpansionFactor'.
4307
2008-08-04 Bram Tassyns <bramt@enfocus.be>
4309
* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
4310
resulted in incorrect scaling. This fixes Savannah bug #23973.
4312
2008-08-04 Werner Lemberg <wl@gnu.org>
4314
Be more tolerant w.r.t. invalid entries in SFNT table directory.
4316
* src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
4318
Add more trace messages.
4319
(tt_face_load_font_dir): Updated.
4321
2008-07-30 Werner Lemberg <wl@gnu.org>
4323
* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
4324
assume that the first argument on the stack is the bottom-most
4325
element. Two reasons:
4327
o According to people from Adobe it is missing in the Type 2
4328
specification that pushing of additional, superfluous arguments
4329
on the stack is prohibited.
4331
o Acroread in general handles fonts differently, namely by popping
4332
the number of arguments needed for a particular operand (as a PS
4333
interpreter would do). In case of buggy fonts this causes a
4334
different interpretation which of the elements on the stack are
4335
superfluous and which not.
4337
Since there are CFF subfonts (embedded in PDFs) which rely on
4338
Acroread's behaviour, FreeType now does the same.
4340
2008-07-27 Werner Lemberg <wl@gnu.org>
4342
Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
4343
fixes Savannah bug #23940.

4371
tt_cmap4_char_map_binary): Handle fonts which treat the last segment
4372
specially. According to the specification, such fonts would be
4373
invalid but acroread accepts them.

where num_locations < num_glyphs. Problem reported by Ding Li.
4402
2008-07-05 Werner Lemberg <wl@gnu.org>
4404
Since FreeType uses `$(value ...)', we now need GNU make 3.80 or

4448
2008-06-27 Werner Lemberg <wl@gnu.org>
4450
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
4451
Horizontal_Gray_Sweep_Drop): Test for intersections which
4452
degenerate to a single point can be ignored; this has been confirmed
4453
by Greg Hitchcock from Microsoft. (This was commented out code.)
4455
2008-06-26 Werner Lemberg <wl@gnu.org>
4457
Improve navigation in API reference.
4459
* src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
4460
(html_header_6): This.
4461
(html_header_3, html_header_3i, html_header_4, html_header_5,
4462
html_header_5t): New strings.
4463
(toc_footer_start, toc_footer_end): New strings.
4464
(HtmlFormatter::html_header): Updated.
4465
(HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
4467
(HtmlFormatter::index_enter): Use `html_index_header'.
4468
(HtmlFormatter::index_exit): Print `html_footer'.
4469
(HtmlFormatter::toc_enter): Use `html_toc_header'.
4470

4472
Convert ~ to non-breakable space.
4474
* src/tools/docmaker/tohtml.py (make_html_para): Implement it.
4475
Update header files accordingly.
4477
2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4479
* builds/unix/configure.raw: Check type `ResourceIndex' explicitly
4480
and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
4481
bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
4482
ResourceIndex type definition. The macro does not inform the type
4484
* src/base/ftmac.c: More parentheses are inserted to clarify the
4485
conditionals to disable legacy APIs in `10.5 and later' cases. If
4486
HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
4488
2008-06-24 Werner Lemberg <wl@gnu.org>
4490
* src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
4493
* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
4494
Draw_Sweep): No-dropout mode is value 2, not value 0.
4495
(Draw_Sweep): Really skip dropout handling for no-dropout mode.
4497
2008-06-24 Werner Lemberg <wl@gnu.org>
4499
* src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
4500
if it consists of one point only. Based on a patch from Savannah
4501
bug #23683 (from John Tytgat).
4503
2008-06-22 Werner Lemberg <wl@gnu.org>
4505
* src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
4508
* docs/CHANGES: Updated.
4510
2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4512
* builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
4513
but LDFLAGS does not, import it to LDFLAGS. The option is used to
4514
specify non-default SDK on Mac OS X (e.g., universal binary SDK for
4515
Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
4516
recommends to add the option only to CFLAGS, LDFLAGS should include
4517
it because libfreetype.la is built with -no-undefined. This fixes a
4518
bug reported by Ryan Schmidt in MacPorts,
4519
http://trac.macports.org/ticket/15331.
4521
2008-06-21 Werner Lemberg <wl@gnu.org>
4523
Enable access to the various dropout rules of the B&W rasterizer.
4524
Pass dropout rules from the TT bytecode interpreter to the
4527
* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
4528
FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
4530
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
4531
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
4532
OpenType specification.
4533
Fix mode 4 computation.
4534
(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
4536
* src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
4537
mode to FT_OUTLINE_XXX flags.
4539
* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
4541
2008-06-19 Werner Lemberg <wl@gnu.org>
4543
* src/cff/cffobjs.c (cff_face_init): Compute final
4544
`dict->units_per_em' value before assigning it to
4545
`cffface->units_per_EM'. Otherwise, CFFs without subfonts are
4546
scaled incorrectly if the font matrix is non-standard. This fixes
4547
Savannah bug #23630.
4549
* docs/CHANGES: Updated.
4551
2008-06-19 Werner Lemberg <wl@gnu.org>

2008-06-15 George Williams <gww@silcom.com>
4565
* src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
4566
`valid->extra2' to 1. This is undocumented in the OpenType 1.5
4569
2008-06-15 Werner Lemberg <wl@gnu.org>
4571
* src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
4572
from clobbering. Patch from Savannah bug report #23556.
4574
* docs/CHANGES: Document it.
4576
2008-06-10 Werner Lemberg <wl@gnu.org>
4578

2008-06-09 VaDiM <s_sliva@rambler.ru>
4618
Support debugging on WinCE. From Savannah patch #6536; this fixes
4621
* builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
4622
as a replacement for OutputDebugStringA (which WinCE doesn't have).
4624
(ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
4625
environment variables.
4627

2008-06-08 Werner Lemberg <wl@gnu.org>
4636
* src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
4637
`private_len' unsigned.
4639
* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
4641
(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
4644
* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.
4647
* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
4652
* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.
4655
* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
4659
* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
4660
`maxTwilightPoints'.
4662
2008-06-06 Werner Lemberg <wl@gnu.org>
4664
* src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
4665
correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
4667
2008-06-03 Werner Lemberg <wl@gnu.org>
4669
* include/freetype/ftcache.h (FTC_FaceID): Change type back to
4670
FT_Pointer. Reported by Ian Britten <britten@caris.com>.
4672
2008-06-02 Werner Lemberg <wl@gnu.org>
4674
Emit header info for defined FreeType objects in reference.
4676
* src/tools/docmaker/content.py (re_header_macro): New regexp.
4677
(ContentProcessor::__init__): Initialize new dictionary `headers'.
4678
(DocBlock::__init__): Collect macro header definitions.
4680
* src/tools/docmaker/tohtml.py (header_location_header,
4681
header_location_footer): New strings.
4682
(HtmlFormatter::__init__): Pass `headers' dictionary.
4683
(HtmlFormatter::print_html_field): Don't emit paragraph tags.
4684

4690
FT_INCREMENTAL_H): Added.
4692
2008-05-28 Werner Lemberg <wl@gnu.org>
4694
* src/tools/docmaker/sources.py (SourceBlock::__init__): While
4695
looking for markup tags, return immediately as soon a single one is
4698
2008-05-28 Werner Lemberg <wl@gnu.org>
4700
* src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
4701
original, unscaled input values. Confirmed by Greg Hitchcock from
4704
2008-05-27 Werner Lemberg <wl@gnu.org>
4706
* src/tools/docmaker/tohtml.py (block_footer_start,
4707
block_footer_middle): Beautify output.
4709
2008-05-25 Werner Lemberg <wl@gnu.org>
4711
* src/raster/ftraster.c (fc_black_render): Return 0 when we are
4712
trying to render into a zero-width/height bitmap, not an error code.
4714
* src/truetype/ttgload.c (load_truetype_glyph): Move initialization
4715
of the graphics state for subglyphs to...
4716
(TT_Hint_Glyph): This function.
4717
Hinting instructions for a composite glyph apparently refer to the
4718
just hinted subglyphs, not the unhinted, unscaled outline. This
4719
seems to fix Savannah bugs #20973 and (at least partially) #23310.
4721
2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4723
* src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid

4727
2008-05-18 Werner Lemberg <wl@gnu.org>
4729
* src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
4730
correction for pixel boundary. Without this patch, the effect can
4731
be cumulative under certain circumstances, making glyphs taller and
4732
taller after each call. This fixes Savannah bug #19976.
4734
2008-05-18 Werner Lemberg <wl@gnu.org>
4736
* src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

4746
declarations non-global.
4748

4750
2008-05-17 Sam Hocevar <samh>
4752

4771
* src/psaux/t1decode.c (t1_decoder_parse_charstrings)
4772
<op_closepath>: `closepath' without a path is a no-op, not an error
4773
(cf. the PS reference manual).
4775
Reported by Martin McBride.

4783
* src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
4784
which contains a single but empty entry. This is technically
4785
invalid (since it must end with `return'), but...
4787
Reported by Martin McBride.
4789
2008-05-14 Werner Lemberg <wl@gnu.org>
4791
Finish fix of scaling bug of CID-keyed CFF subfonts.

4794
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
4797
* src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
4798
provide global hinting data for both the top-font and all subfonts
4799
(with proper scaling).
4801
* src/cff/cffobjs.c (cff_make_private_dict): New function, using
4802
code from `cff_size_init'.

4804
Use CFF_Internal and handle subfonts.
4805
(cff_face_init): Handle top-dict and subfont matrices correctly;
4806
apply some heuristic in case of unlikely matrix concatenation
4807
results. This has been discussed with people from Adobe (thanks
4808
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy

4837
* src/base/cff/cffparse.c (power_tens): New array.
4838
(cff_parse_real): Rewritten to introduce a fourth parameter which
4839
returns the `scaling' of the real number so that we have no
4840
precision loss. This is not used yet.

2008-05-03 Werner Lemberg <wl@gnu.org>
4847
* src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
4848
transformation since it recursively calls FT_Load_Glyph. This fixes

4944
2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4946
* src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
4947
synthesis. For any face of a specified FOND, always the name for
4948
the first face was used. Except of a FOND that refers multiple
4949
Type1 font files, wrong synthesized font names are not used at all,
4950
so this is an invisible bug. A few limit checks are added too.
4952
* builds/mac/ftmac.c: Ditto.
4954
2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4956
* builds/unix/configure.raw: Split compiler option to link Carbon
4957
frameworks to one option for CoreServices framework and another
4958
option for ApplicationServices framework. The split options can be
4959
managed by GNU libtool to avoid unrequired duplication when FreeType
4960
is linked with other applications. Suggested by Daniel Macks,
4961
Savannah bug #22366.
4963
2008-02-18 Victor Stinner <victor.stinner@haypocalc.com>

2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4975
* src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
4976
handle by its value instead of ResError(), fix provided by Deron
4977
Kazmaier. According to the Resource Manager Reference,
4978
GetResource(), Get1Resource(), GetNamedResource(),
4979
Get1NamedResource() and RGetResource() set noErr but return NULL
4980
handle when they can not find the requested resource. These
4981
functions never return undefined values, so it is sufficient to
4982
check if the handle is not NULL.
4984
* builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
4986
2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4988
* src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
4989
inclusion styles. Now it always includes src/base/ftmac.c;
4990
builds/mac/ftmac.c is never included in any configuration.
4992
* builds/unix/configure.raw: Print warning if configure is executed
4993
with options to specify Carbon functionalities explicitly.
4995
* docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
4996
included automatically and manual replacement is required.

5050
Improvement of POSIX resource-fork accessor to load unsorted
5051
references in a resource. In HelveLTMM (resource-fork PostScript
5052
Type1 font bundled with Mac OS X since 10.3.x), the appearance order
5053
of PFB chunks is not sorted; sorting the chunks by reference IDs is
5056
* include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
5057
type to store a pair of reference ID and offset to the chunk.
5059
* src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
5060
sort FT_RFork_Ref by their reference IDs.
5062
(FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
5063
sorted by reference ID.
5065
2007-12-14 Werner Lemberg <wl@gnu.org>
5067
* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
5068
division too early; otherwise the most significant digit(s) of the
5069
final result are lost as the value is truncated to an integer. This
5070
fixes Savannah bug #21794 (where the patch has been posted too).
5072
2007-12-06 Fix <4d876b82@gmail.com>
5074
Pass options from one configure script to another as-is (not
5075
expanded). This is needed for options like
5076
--includedir='${prefix}/include'.
5078
* builds/unix/detect.mk, configure: Prevent argument expansion in
5079
call to the (real) `configure' script.
5081
2007-12-06 Werner Lemberg <wl@gnu.org>

5088
There exist CFFs which contain opcodes for the Type 1 operators
5089
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
5090
However, it doesn't harm to support them.
5092
* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
5094
(cff_argument_counts): Ditto.
5096
(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
5097
and 13 (hsbw) which are invalid in Type 2 charstrings.
5099
2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5101
* src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
5102
support new pathname syntax `..namedfork/rsrc' to access a resource
5103
fork on Mac OS X. The legacy syntax `/rsrc' does not work on
5104
case-sensitive HFS+.
5105
(raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
5106
buffer size to store a pathname.

5145
Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
5146
not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
5147
cannot mmap() the specified file and cannot seek to head of the
5148
specified file, it returns NULL stream and FT_Open_New() returns the
5149
error immediately. On MacOS, most legacy MacOS fonts fall into such
5150
a scenario because their data forks are zero-sized and cannot be
5151
sought. To proceed to guessing of resource fork fonts, the
5152
functions for legacy MacOS font must properly handle the NULL stream
5153
returned by FT_New_Stream().
5155
* src/base/ftobjs.c (IsMacBinary): Return error
5156
FT_Err_Invalid_Stream_Operation immediately when NULL stream is
5158
(FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
5159
to fallback. Originally, legacy MacOS font is tested in the cases
5160
of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
5161
or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
5162
.dfont header is combined). Now the case of
5163
FT_Err_Cannot_Open_Stream is included.
5165
* src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
5166
skip FT_Stream_Seek(), which seeks to the head of stream, and
5167
proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
5168
for a NULL stream causes a Bus error on Mac OS X.
5169
(raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
5170
immediately if passed stream is NULL.
5171
(raccess_guess_apple_single): Ditto.
5173

5175
Fix for Carbon incompatibilities since Mac OS X 10.5,
5176
proposed by Sean McBride.
5178
* doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
5180
* include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
5181
FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
5182
Carbon functions from a forked process is classified as unsafe
5183
by Apple. All Carbon-dependent functions should be deprecated.
5185
* src/base/ftmac.c: Use essential header files
5186
<CoreServices/CoreServices.h> and
5187
<ApplicationServices/ApplicationServices.h> instead of
5188
all-in-one header file <Carbon/Carbon.h>.
5190
Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
5191
genuine macro PATH_MAX.
5193
Add fallback macro for kATSOptionFlagsUnRestrictedScope which
5194
is not found in Mac OS X 10.0.
5196
Multi-character constants ('POST', 'sfnt' etc) are replaced by
5197
64bit constants calculated by FT_MAKE_TAG() macro.
5199
For the index in the segment of resource fork, new portable
5200
type ResourceIndex is introduced for better compatibility.
5201
This type is since Mac OS X 10.5, so it is defined as short
5202
when built on older platforms.
5204
(FT_ATSFontGetFileReference): If build target is only the systems
5205
10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
5207
(FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
5208
and newer or 64bit platform, because legacy type FSSpec type is
5211
(FT_New_Face_From_FSSpec): Ditto.
5213
2007-11-01 Werner Lemberg <wl@gnu.org>
5215
* src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
5216
fixes Savannah bug #21485.
5218
2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
5220
* src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
5221
can handle the font at all, then check `face_index'. Otherwise, the
5222
driver might return the wrong error code. This fixes Savannah bug
5225
2007-10-21 Werner Lemberg <wl@gnu.org>
5227
* src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
5228
support for bit 8 of the `fsSelection' field in the `OS/2' table.
5229
MS is already using this; hopefully, this becomes part of OpenType
5231
Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
5234
2007-10-20 Werner Lemberg <wl@gnu.org>
5236
* src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
5237
Add `td.left' element to CSS.
5238
(toc_section_enter): Use it.
5240
2007-10-18 David Turner <david@freetype.org>
5242
* include/freetype/freetype.h, src/base/ftobjs.c: Rename API
5243
functions related to cmap type 14 support to the
5244
`FT_Object_ActionName' scheme:
5246
FT_Get_Char_Variant_index -> FT_Face_GetCharVariantIndex
5247
FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
5248

5249
FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar
5250
FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant
5252
Update documentation accordingly.
5254
* src/sfnt/ttcmap.c: Stronger cmap 14 validation.
5255
Make the code a little more consistent with FreeType coding
5256
conventions and modify the cmap14 functions that returned a newly
5257
allocated array to use a persistent vector from the TT_CMap14 object
5260

2007-01-30 David Turner <david@freetype.org>
6434
Tag sources with VER-2-3-1 to prepare release.
6436
* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
6438
* docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
6441
* builds/unix/configure.raw (version_info): Set to 9:12:3.
6444
* src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
6445
(af_loader_load_g): Disable the warper (i.e., the light hinting
6446
improvements) to make a 2.3.1 bugfix release before introducing a
6447
new feature. This should give us more time to tune and improve the
6448
warper for the next release.
6450
* docs/CHANGES: Update accordingly.
6452
2007-01-25 David Turner <david@freetype.org>
6454
For light auto-hinting, improve glyph advance widths and resurrect
6455
normal/full hinting to its normal quality.
6457
* src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
6459
* src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
6462
* src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
6463
preprocessor conditional with if-clause, handling both light and
6466
* src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.

6483
2007-01-25 Werner Lemberg <wl@gnu.org>
6485
* src/cff/cffload.c (cff_index_get_pointers): Handle last entry
6486
correctly in a sanity check. Since this function is only used to
6487
load local and global functions, any charstring that called the last
6488
local/global function would fail otherwise. This fixes Savannah bug
6491
* docs/CHANGES: Document it.

6497
bytecode interpreter in the TrueType font driver.

6501
not necessarily a final version, but it seems to work well.

* src/autofit/afwarp.c (AF_WarpScore): Tune table.
6509
(af_warper_compute_line_best): Fix array size of `scores'.
6510
(af_warper_compute): Better handling of border cases.
6511
* src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
6514

6583
versions up to 0x3FF without complaining.

* src/base/ftobjs.c (IsMacResource): Fix a small bug that caused a
6643
crash with some Mac OS X .dfont files. Submitted by Masatake
6646
* autogen.sh: Small fix to get it working on Mac OS X properly:
6647
The issue is that GNU libtool is called `glibtool' on this platform,
6648
and we must call `glibtoolize', since `libtoolize' doesn't exist.
6650

6709
2007-01-04 David Turner <david@freetype.org>
6711
* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
6712
correctly. This fixes Savannah bug #17876.
6715
Do not allocate interpreter-specific tables in memory if we are not
6716
going to load glyphs with the bytecode interpreter anyway.
6718

(tt_size_reset): Move some code to `tt_size_ready_bytecode'.
6731
Don't extract the metrics table from the SFNT font file. Instead,
6732
reparse it on each glyph load. The runtime difference is not
6733
noticeable, and it can save a lot of heap memory when memory-mapped
6736
* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
6737
`horz_metrics_offset' and `vert_metrics_ofset'.

ft_black_set_mode, ft_black_render): Updated.
6791
(ft_black_init): Don't initialize `count_table'.

6810
the optimization is no longer experimental.
6812
* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
6813
Remove a typo that results in no hinting and a memory leak with some
6814
large Asian CFF fonts.
6816
* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
6817
which happens when FT_Done_Library is called with still opened
6818
CFF_Faces in it. We need to close all faces before destroying the
6819
modules, or else some bad things (memory leaks) may happen.

6904
xlc v5 under AIX 4.3 doesn't like this.
6906
2006-12-07 David Turner <david@freetype.org>
6908
* src/autofit/afloader.c (af_loader_load_g): Small adjustment
6909
to the spacing of auto-fitted glyphs. This only impacts rare

6952
af_glyph_hints_dump_segments, af_glyph_hints_dumpedges) [!AF_DEBUG]:
6953
Add stubs to link the `ftgrid' test program when debugging is

program after a change from mono to grayscaling (and vice versa).
6981
Use correct constant for comparison to get `exec->grayscale'.
6983
2006-11-18 Werner Lemberg <wl@gnu.org>
6985
Because FT_Load_Glyph expects CID values for CID-keyed fonts, the
6986
test for a valid glyph index must be deferred to the font drivers.
6987
This patch fixes Savannah bug #18301.
6989
* src/base/ftobjs.c (FT_Load_Glyph): Don't check `glyph_index'.
6990

7002
* src/base/ftlcdfil.c: Add support for FT_FORCE_LIGHT_LCD_FILTER and
7003
FT_FORCE_LEGACY_LCD_FILTER at compile time. Define these macros
7004

7012
filter. The FT_LcdFilter value is an enumeration describing which
7013
filter to apply, with new values FT_LCD_FILTER_LIGHT and
7014
FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
7015
algorithm which produces strong color fringes for everything
7016
except very-well hinted text).

7060
Add more debugging messages.
7062
* src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
7063

7064
*many* corner cases with serifs.
7065
(af_latin_align_linked_edge): Add logging message.
7066
(af_latin_hint_edges): Use AF_HINTS_DO_BLUES.

7087
* src/autofit/afhints.c: Include FT_INTERNAL_CALC_H.
7088
(af_direction_compute): Add a missing FT_ABS call. This bug caused
7089
production of garbage by missing lots of segments.
7091
* src/autofit/afhints.h (AF_HINTS_DO_BLUES): New macro.
7093
* src/autofit/afloader.c (af_loader_init, af_loader_done)

* src/base/ftoutln.c (FT_Outline_Get_Orientation): Re-implement to
7114
better deal with broken Asian fonts with strange glyphs, having
7115
self-intersections and other peculiarities. The used algorithm is
7116
based on the nonzero winding rule.
7118
2006-10-23 David Turner <david@freetype.org>
7120
Speed up the CFF font loader. With some large CFF fonts,
7121
FT_Open_Face is now more than three times faster.
7123
* src/cff/cffload.c (cff_get_offset): Removed.
7124
(cff_new_index): Inline functionality of `cff_get_offset'.
7125

7243
* include/freetype/freetype.h (FT_FREETYPE_PATCH): Set to 2.
7246
Add a new API to support color filtering of subpixel glyph bitmaps.
7247
In a default build, the function `FT_Library_SetLcdFilter' returns
7248
`FT_Err_Unimplemented_Feature'; you need to #define
7249
FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
7250
real implementation.
7252
* include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

* src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
7299
LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
7300
isn't defined at compile time. This only changes the content of the
7301
rendered glyph to match the one of normal gray-level rendering,
7302
hence clients should not need to be modified.
7304
* docs/CHANGES: Updated.
7306
2006-09-18 Garrick Meeker <garrick@digitalanarchy.com>
7308

7702
The Type 1 parser now skips over top-level procedures as required
7703
for a `Simplified Parser'. This makes the parser more robust as it

* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
7819
of `face->num_glyphs' which missed the last glyph, due to
7820
the offset-by-1 computation, since the PFR format doesn't
7821
guarantee that glyph index 0 corresponds to the `missing

* src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
7854
its content cannot be parsed as supported font. This fixes
7855
the second part of Savannah bug #16590.

7864
This is a major patch used to drastically improve the performance of
7865
loading glyphs. This both speeds up loading the glyph vectors
7866
themselves and the auto-fitter module.
7868
We now use inline assembler code with GCC to implement `FT_MulFix',
7869
which is probably the most important function related to the
7870
engine's performance.
7872
The resulting speed-up is about 25%.
7875
* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
7876
`cursor' and `limit'.
7878
* src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
7880
(AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
7883
* src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
7886
* src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
7888
(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
7889
(af_glyph_hints_reload: Rewrite recognition of weak points.
7891
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
7892
constant values out of the loops.
7894
* src/autofit/aftypes.h: Updated.
7896
* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
7898
* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
7899
product to get orientation.
7901
* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
7902
(FT_Stream_OpenGzip): Use it to handle small files directly in
7905
* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
7906
Improve performance.
7908
* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
7911
(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
7912
TT_Load_Composite_Glyph): Updated. Add threshold to protect against
7913
exceedingly large values of number of contours. Speed up by
7914
reducing the number of loops.
7916
* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
7919
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
7920
used to detect rogue clients from 4 to 16. This is to prevent some
7921
segmentation faults with fonts like `KozMinProVI-Regular.otf' which
7922
comes from the Japanese Adobe Reader Asian Font pack.
7924
2007-05-17 Werner Lemberg <wl@gnu.org>
7926
* src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
7927
fixes the first part of Savannah bug #16590.
7929
2006-05-16 Werner Lemberg <wl@gnu.org>
7931
* docs/PROBLEMS: Updated icl issues.
