the number of the subtables in the state tables; classTable,
stateArray, entryTable.
2012-01-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[raccess] Modify for PIC build.
Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html
Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
are renamed with `ft_' suffixes.
* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
to `ft_raccess_rule_by_darwin_vfs()'.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Declarations of FT_RFork_Rule,
raccess_guess_rec, are moved to...
* include/freetype/internal/ftrfork.h: Here.
* include/freetype/internal/ftrfork.h:
FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
to replace raccess_guess_table[] in both of PIC and non-PIC
modes.
* src/base/ftrfork.c: raccess_guess_table[] array is rewritten
by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.
* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
the function pointer from `ft_raccess_guess_table' storage in
`BasePIC' structure.
* src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
FT_RACCESS_GUESS_TABLE_GET.
(raccess_get_rule_type_from_rule_index): Add `library' as the
first argument to the function, to retrieve the storage of
`ft_raccess_guess_table' from it. Also `raccess_guess_table'
is replaced by FT_RACCESS_GUESS_TABLE_GET.
(ft_raccess_rule_by_darwin_vfs): Ditto.
2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Remove trailing spaces.
2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Formatting PIC related sources.

* src/base/basepic.c: Ditto.
* src/base/ftpic.c: Ditto.
* src/cff/cffpic.c: Ditto.

* src/smooth/ftspic.c: Ditto.
* src/truetype/ttpic.c: Ditto.
2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[autofit] Fix the inclusion of `aflatin2.h' in PIC file.
* src/autofit/afpic.c: Include `aflatin2.h' when
FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
Unconditionally inclusion causes declared but unimplemented
warning by GCC 4.6.
2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
* src/cff/cffpic.c: The declarations of
FT_Init_Class_cff_cmap_encoding_class_rec() and
FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
They can be obtained by the inclusion of cffcmap.h.
cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix redundant declaration warning in PIC mode.
Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
designed to declare xxx_pic_{free,init} by themselves.
Because these macros are used at the end of the module
interface (e.g. ttdriver.c) and the wrapper source to build
a module as a single object (e.g. truetype.c) includes
the PIC file (e.g. ttpic.c) before the module interface,
these macros are expanded AFTER xxx_pic_{free,init} body
when the modules are built as single object.
The declaration after the implementation causes the redundant
declaration warnings, so the declarations are moved to module
PIC headers (e.g. ttpic.h). Separating to other header files
are needed for multi build.
* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
Remove class_##_pic_free and class_##_pic_init declarations.
* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
FT_DEFINE_MODULE): Ditto.
* src/base/basepic.h: Insert a comment and fix coding style.
* src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
init}.
* src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
init}.
* src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
init}.
* src/raster/rastpic.h: Declare
ft_raster{1,5}_renderer_class_pic_{free,init}
* src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
* src/smooth/ftspic.h: Declare
ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
* src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Make pspic.c to include module error header to fix multi build.
* src/psnames/pspic.c: Include `psnamerr.h'.
2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[base] Fix a dereference of uninitialized variable in PIC mode.
* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
set before derefering to obtain `library'. The initialization
of `clazz', `glyph', `library' and NULL pointer check are
reordered to minimize PIC conditonals.
2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[base] Insert explicit cast for GCC 4.6 in PIC mode.
* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
configuration, FT_DEFAULT_MODULES_GET returns
FT_Module_Class** pointer, GCC 4.6 warns that
const FT_Module_Class* const* variable is warned as
inappropriate to store it. To calm it, explicit cast is
inserted. Also `library' is checked to prevent the NULL
pointer dereference in FT_DEFAULT_MODULES_GET.
2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
take no arguments but derefer the variable named `library'
internally.
* src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
set it if non-NULL driver is passed.
* src/truetype/ttdriver.c (tt_get_interface): Ditto.
* src/sfnt/sfdriver.c (sfnt_get_interface): Declare `library'
under PIC configuration, and set it if non-NULL module is given.
* src/psnames/psmodule.c (psnames_get_interface): Ditto.
2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Make PIC files include module error headers, to use the error codes
with per-module prefix.
* src/autofit/afpic.c: Include `aferrors.h'.
* src/cff/cffpic.c: Include `cfferrs.h'.
* src/pshinter/pshpic.c: Include `pshnterr.h'.
* src/raster/rastpic.c: Include `rasterrs.h'.
* src/sfnt/sfntpic.c: Include `sferrors.h'.
* src/smooth/ftspic.c: Include `ftsmerrs.h'.
* src/truetype/ttpic.c: Include `tterrors.h'.
2012-01-04 Tobias Ringström <tobias@ringis.se>
[truetype] Fix IP instruction if x_ppem != y_ppem.
* src/truetype/ttinterp.c (Ins_IP): Scale `orus' coordinates
properly.
2012-01-02 Werner Lemberg <wl@gnu.org>
Fix tracing message for `loca' table.
* src/truetype/ttpload.c (tt_face_get_location): Don't emit a
warning message if the last `loca' entry references an empty glyph.
2011-12-10 Werner Lemberg <wl@gnu.org>
Add some variable initializations.
Reported by Richard COOK <rscook@unicode.org>.
* src/type1/t1driver.c (t1_ps_get_font_value): Initialize `val'.
* src/smooth/ftgrays.c (gray_render_conic): Initialize `levels'
earlier.
2011-12-08 Werner Lemberg <wl@gnu.org>
Fix serious scaling bug in `FT_Get_Advances'.
* src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by
`FT_Load_Glyph' must be simply multiplied by 1024.
2011-12-08 Werner Lemberg <wl@gnu.org>
* src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing.
2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
was a configurable macro to disable Carbon-dependent code. Because
now configure script sets DARWIN_NO_CARBON by default and disables
Darwin & Carbon-dependent codes, these macros can be unified.
FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
(defined by default) is removed, because DARWIN_NO_CARBON violates
FT_XXX naming convention of public macros, and a macro configured by
default is not portable for the building without configure (e.g.
make devel).
* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
old Mac font support is requested and Carbon is available.
* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is
requested.
* include/freetype/config/ftconfig.in: Ditto.
* builds/vms/ftconfig.h: Ditto.
* src/base/ftbase.h: Remove DARWIN_NO_CARBON.
* src/base/ftbase.c: Ditto.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Ditto.
* src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
(same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
* builds/mac/ftmac.c: Ditto.
* builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
* builds/mac/FreeType.m68k_far.make.txt: Ditto.
* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix Savannah bug #34728 (`make devel' on Mac OS X).
* builds/toplevel.mk: Check `/dev/null' to identify the Unix-
like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4).
* builds/unix/detect.mk: Ditto.
2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[apinames] Fix the overflow of signed integer hash.
* src/tools/apinames.c (names_add): Change the type of `h' from
int to unsigned int, to prevent undefined behaviour in the
overflow of signed integers (overflow of unsigned int is defined
to be wrap around). Found by clang test suggested by Sean
McBride.
2011-11-30 Werner Lemberg <wl@gnu.org>
[winfonts] Remove casts.
* src/winfonts/winfnt.c (winfnt_driver_class): Remove all casts and
update affected functions.
(FNT_Size_Select): Fix number of arguments.

* src/type1/t1driver.c (t1_driver_class): Remove all casts and
update affected functions.
* src/type1/t1gload.c, src/type1/t1gload.h, src/type1/t1objs.c:
Updated for t1driver changes.
src/type1/t1objs.h (T1_Driver): Remove unused typedef.
Updated for t1driver changes.
2011-11-27 Werner Lemberg <wl@gnu.org>
[bdf] Fix Savannah bug #34896.
ENCODING now covers the whole Unicode range.
Note, however, that this change is quite expensive since it
increases the size of three arrays by almost 400kByte in total. The
right fix is to replace the logic with something smarter.
Additionally, there exist very old BDFs for three-byte CCCII
encoding which exceeds the range of Unicode (another reason to have
a smarter logic).
* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
arrays.
* src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.
2011-11-27 Werner Lemberg <wl@gnu.org>

src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c
(T42_Face_Init), src/winfonts/winfnt.c (FNT_Face_Init): Add
`greeting' message.
* src/sfnt/sfobjs.c (sfnt_open_font), src/type42/t42objs.c
(T42_Open_Face): Improve tracing.

2011-11-26 Werner Lemberg <wl@gnu.org>
Add new error code FT_Err_Missing_Module.
Previously, FreeType misleadingly returned
FT_Err_Unknown_File_Format if a module was missing (or a test was
missing completely).
* include/freetype/fterrdef.h (FT_Err_Missing_Module): Define.
* src/cff/cffobjs.c (cff_face_init), src/cff/cffdrivr.c
(cff_get_glyph_name), src/cid/cidobjs.c (cid_face_init),
src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c

* src/type1/t1afm.c (T1_Read_Metrics), src/type/t1objs.c
(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Remove now
redundant test for `psaux'.
2011-11-25 Werner Lemberg <wl@gnu.org>
[bdf] Add more error messages.
* src/bdf/bdflib.c (_bdf_set_default_spacing, _bdf_add_property):
Add line number argument.
Update all callers.

[smooth] Slightly optimize conic and cubic flatterners.

out some code from the main loop to speed it up.
2011-09-11 Tomas Hoger <thoger@redhat.com>
Slightly improve LZW_CLEAR handling.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
handled as clear codes. This also re-sets old_code and old_char to
predictable values, which is a little better than using `random'
ones if the code following LZW_CLEAR is invalid.
2011-09-11 Tomas Hoger <thoger@redhat.com>
Add explicit LZW decompression stack size limit.
Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
constructed correctly. It's even less than that, see e.g.
libarchive code comment for a better size upper bound:
http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
This patch adds explicit stack size limit, enforced when stack is
realloced.
An alternative is to ensure that code < state->prefix[code - 256]
when traversing prefix table. Such check is less efficient and
should not be required if prefix table is constructed correctly in
the first place.
* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
2011-09-11 Tomas Hoger <thoger@redhat.com>
Protect against loops in the prefix table.
LZW decompressor did not sufficiently check codes read from the
input LZW stream. A specially-crafted or corrupted input could
create a loop in the prefix table, which leads to memory usage
spikes, as there's no decompression stack size limit.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
code in valid LZW stream must be 0..255.
<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
code > free_ent is invalid.

[ftstroke] Major revision.
The main problems
-----------------
o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
joins (not bevel joins) were generated. Indeed, the meanings of
`miter' and `bevel' were incorrectly reversed (consistently) in
both the code and comments.
o The way bevel joins were constructed (whether specified
explicitly, or created as a result of exceeding the miter limit)
did not match what is required for stroked text in PostScript or
PDF.
The main fixes
--------------
o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
introduced to support PostScript and PDF miter joins.
o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
alias for FT_STROKER_LINEJOIN_MITER.
Additionally, a variety of stroking errors have been fixed. These
would cause various artifacts (including points `at infinity'),
especially when stroking poor quality fonts.
See
http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
for example documents. The FreeType stroker now produces results
very similar to that produced by GhostScript and Distiller for these
fonts.
Other problems
--------------
The following problems have been resolved:
o Inside corners could be generated incorrectly. Intersecting the
inside corner could cause a missing triangular area and other
effects.
The intersection point can only be used if the join is between
two lines and both lines are long enough. The `optimization'
condition in `ft_stroker_inside' has been corrected; this
requires the line length to be passed into various functions and
stored in `FT_StrokerRec'.
o Incorrect cubic curves could be generated. The angle
calculations in `FT_Stroker_CubicTo' have been corrected to
handle the case of the curve crossing the +/-PI direction.
o If the border radius was greater than the radius of curvature of
a curve, then the negative sector would end up outside (not
inside) the border. This situation is now recognized and the
negative sector is circumnavigated in the opposite direction.
(If round line joins are being used, this code is disabled
because the line join will always cover the negative sector.)
o When a curve is split, the arcs may not join smoothly (especially
if the curve turns sharply back on itself). Changes in
direction between adjacent arcs were not handled. A round
corner is now added if the deviation from one arc to the next is
greater than a suitable threshold.
o The current direction wasn't retained if a the outline contained
a zero length lineto or a curve that was determined to be
`basically a point'. This could cause a spurious join to be
added.
o Cubics with close control points could be mishandled. All eight
cases are now distinguished correctly.
Other improvements
------------------
o Borders for cubic curves could be too `flat'.
FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
this.
o The handling and use of movable points has been simplified a
little.
o Various values are now computed only if the results are actually
needed.
o The directions of the outer and inner borders have been swapped,
as recommended by Graham Asher.

suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[autofit] Add bluezones for CJK Ideographs.
To remove extremas of vertical strokes of CJK Ideographs at
low resolution and make the top and bottom horizontal stems
aligned, bluezones for CJK Ideographs are calculated from
sample glyphs. At present, vertical bluezones (bluezones
to align vertical stems) are disabled by default. For detail, see

2011-04-25 Kan-Ru Chen <kanru@kanru.info>
[truetype] Always check the checksum to identify tricky fonts.
Because some PDF generators mangle the family name badly,
the trickyness check by the checksum should be invoked always.
For sample PDF, see
http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html
* src/truetype/ttobjs.c (tt_check_trickyness): Even when
tt_check_trickyness_family() finds no trickyness,
tt_check_trickyness_sfnt_ids() is invoked.

2011-04-21 Behdad Esfahbod <behdad@behdad.org>
Always ignore global advance.
This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
deprecated, and ignored. The new behavior is what every major user
of FreeType has been requesting. Global advance is broken in many
CJK fonts. Just ignoring it by default makes most sense.
* src/truetype/ttdriver.c (tt_get_advances),

[autofit] Blur CJK stems if too many to preserve their gaps.
When there are too many stems to preserve their gaps in the
rasterization of CJK Ideographs at a low resolution, blur the
stems instead of showing clumped stems. See
http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html
http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html
for details.
* src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
the previous stem by `has_last_stem' and `last_stem_pos', and skip
a stem if the current and previous stem are too near to preserve
the gap.

2011-04-11 Kan-Ru Chen <kanru@kanru.info>
Fix reading of signed integers from files on 64bit platforms.
Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension. For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.
We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.

Copy the maintained code from builds/unix/ftconfig.in.
Old GNU binutils could not accept the reduced syntax
`orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
`orr %0, %0, %2, lsl #16' is better. Reported by
Johnson Y. Yan. The bug report by Qt developers is
considered too.

[raster] Make bbox handling the same as with Microsoft's rasterizer.
Right before B/W rasterizing, the bbox gets simply rounded to
integers. This fixes, for example, glyph `three' in font `Helvetica
Neue LT Com 65 Medium' at 11ppem.
Thanks to Greg Hitchcock who explained this behaviour.
* src/raster/ftrend1.c (ft_raster1_render): Implement it.
2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
* builds/unix/configure.raw: Consider recent gcc-standard
flags to specify architecture in CFLAGS & LDFLAGS
harmonization. Requested by Savannah bug #32114, to
support multilib feature of BuildRoot SDK correctly.
2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
* builds/unix/configure.raw: Some important options that
included in CFLAGS but not in LDFLAGS are copied to
LDFLAGS, but the last option in CFLAGS was not checked.
2011-01-13 Werner Lemberg <wl@gnu.org>
[raster] Add undocumented drop-out rule to the other bbox side also.
* src/raster/ftraster.c (Vertical_Sweep_Drop,
Horizontal_Sweep_Drop): Implement it.
2011-01-13 Werner Lemberg <wl@gnu.org>
[raster] Reduce jitter value.
This catches a rendering problem with glyph `x' from Tahoma at
10ppem. It seems that the increase of the precision in the change
from 2009-06-11 makes a larger jitter value unnecessary.
* src/raster/ftraster.c (Set_High_Precision): Implement it.
2011-01-13 Werner Lemberg <wl@gnu.org>
[raster] Handle drop-outs at glyph borders according to Microsoft.
If a drop-out rule would switch on a pixel outside of the glyph's
bounding box, use the right (or top) pixel instead. This is an
undocumented feature, but some fonts like `Helvetica Neue LT Com 65
Medium' heavily rely on it.
Thanks to Greg Hitchcock who explained this behaviour.
* src/raster/ftraster.c (Vertical_Sweep_Drop,
Horizontal_Sweep_Drop): Implement it.

[cache] Fix Savannah bug #31923, patch drafted by Harsha.
When a node comparator changes the cached nodes during the
search of a node matching with queried properties, the
pointers obtained before the function should be updated to
prevent the dereference to freed or reallocated nodes.
To minimize the rescan of the linked list, the update is
executed when the comparator notifies the change of cached
nodes. This change depends previous change:
38b272ffbbdaae276d636aec4ef84af407d16181
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
top node if the cached nodes are changed.
* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] Notice if a cache query induced the node list change.
Some node comparators (comparing the cache node contents and the
properties specified by the query) can flush the cache node to
prevent the cache inflation. The change may invalidate the pointers
to the node obtained before the node comparison, so it should be
noticed to the caller. The problem caused by the cache node
changing is reported by Harsha, see Savannah bug #31923.
* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
`FT_Bool* list_changed' to indicate the change of the cached nodes
to the caller.
(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
`_list_changed'.
(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
and update it when `FTC_Manager_FlushN' flushes any nodes.
* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
FTC_Node_CompareFunc type.
(ftc_gnode_compare): Ditto.
* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
TRUE/FALSE macros.
(ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
list_changed' to indicate the change of the cache nodes (anyway, it
is always FALSE).
* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
TRUE/FALSE macros.
(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
indicate the change of the cache nodes (anyway, it is always FALSE).
(ftc_cmap_node_remove_faceid): Ditto.
* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
`FTC_CACHE_TRYLOOP_END', because the result is not needed.
(FTC_Cache_Lookup): Watch the change of the cache nodes by
`list_changed'.
(FTC_Cache_RemoveFaceID): Ditto.
* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
TRUE/FALSE macros.
(ftc_gnode_compare): New argument `FT_Bool* list_changed' to
indicate the change of the cache nodes (anyway, it is always FALSE).
(FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
passed to `ftc_gnode_compare'.
* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
list_changed' to indicate the change of the cache nodes, anyway. It
is updated by `FTC_CACHE_TRYLOOP'.
(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
passed to `ftc_snode_compare'.
* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
prototype.
* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
`cache' is not used by its child `ftc_gnode_compare'.
2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] Deduplicate the code to get the top node by a hash.
There are several duplicated code fragments getting the top node
from a cache by a given hash, like:
idx = hash & cache->mask;
if ( idx < cache->p )
idx = hash & ( cache->mask * 2 + 1 );
pnode = cache->buckets + idx;
To remove duplication, a cpp-macro to do same work
`FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
configuration, non-`ftc_get_top_node_for_hash' is also introduced.
* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
and implement inlined version.
(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
version.
(ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
(ftc_node_hash_link): Ditto.
(FTC_Cache_Lookup): Ditto.
2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] inline-specific functions are conditionalized.
* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
inlined configuration. This function is a thin wrapper of
`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
`nodecmp' argument). Under non-inlined configuration,
`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
`FTC_Cache->clazz.node_compare'.
* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
`ftc_snode_compare'.
* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] Correct a type mismatch under non-inlined config.
* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
takes the node via a pointer `FTC_Node*', differently from cpp-macro
`FTC_CACHE_LOOKUP_CMP'.
2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Update Jamfile to include Bzip2 support.

(e.g. compressed BDF fonts are not supported yet)
2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Update Symbian project files to include Bzip2 support.
Currently, it provides `FT_Stream_OpenBzip2' that returns

Update Amiga makefiles to include Bzip2 support.
Currently, it provides `FT_Stream_OpenBzip2' that returns
unimplemented error always, to prevent unresolved symbol
error for the applications designed for Unix systems.

2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Update pkg-config tools to reflect Bzip2 support.
* builds/unix/freetype-config.in: Include `-lbz2' to
--libs output, if built with Bzip2 support.
* builds/unix/freetype2.in: Ditto.
2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
* builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
SYSTEM_ZLIB is used to switch the builtin zlib source
or system zlib source out of FreeType2. But ftbzip2
module has no builtin bzip2 library and always requires
system bzip2 library. Thus SYSTEM_BZ2LIB is always yes,
it is not used.

2010-12-25 Harsha <mm.harsha@gmail.com>
Apply Savannah patch #7422.
If we encounter a space in a string then the sbit buffer is NULL,
height and width are 0s. So the check in ftc_snode_compare will
always pass for spaces (comparision with 255). Here the comments
above the condition are proper but the implementation is not. When
we create an snode I think it is the proper way to initialize the
width to 255 and then put a check for being equal to 255 in snode
compare function.
* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
value 255.
(ftc_snode_compare): Fix condition.
2010-12-13 Werner Lemberg <wl@gnu.org>
Fix parameter handling of `FT_Set_Renderer'.
Reported by Kirill Tishin <siege@bk.ru>.

[cff] Allow `hlineto' and `vlineto' without arguments.
We simply ignore such instructions. This is invalid, but it doesn't
harm; and indeed, there exist such subsetted fonts in PDFs.
Reported by Albert Astals Cid <aacid@kde.org>.
* src/cff/cffgload.c (cff_decoder_parse_charstrings)
[cff_op_hlineto]: Ignore instruction if there aren't any arguments

Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'.
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert
the type of `_idx' from FT_PtrDist (by previous change)
to original FT_UFast, to match with FT_CacheRec.
2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] Change the hash types to FT_PtrDist.
On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
variables are inappropriate to calculate hash values
from the memory address (64-bit). The hash variables
are extended from FT_ULong to FT_PtrDist and new
hashing macro functions are introduced. The hash
values on 16-bit memory platforms are changed, but
ILP32 and LP64 are not changed. The hash value in
the cache subsystem is not reverted to the memory
address, so using signed type FT_PtrDist is safe.
* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
function to replace `FTC_FACE_ID_HASH' for portability.
* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
`FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.
* src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
* src/cache/ftccache.h (FTC_NodeRec): The type of the
member `hash' is changed from FT_UInt32 to FT_PtrDist.
* src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
argument `hash' is changed from FT_UInt32 to FT_PtrDist.
(FTC_Cache_NewNode): Ditto.
* src/cache/ftccache.c (ftc_cache_add): Ditto.
(FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
* src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
* src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
of the internal variable `hash' is changed to FT_PtrDist
from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
(FTC_SBitCache_Lookup): Ditto.
(FTC_SBitCache_LookupScaler): Ditto.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
Also the type of the internal variable `_idx' is changed to
FT_PtrDist from FT_UFast for better pointer calculation.
2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cache] Hide internal macros incompatible with LLP64.
`FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and
`FTC_IMAGE_TYPE_HASH' are enclosed by
FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
normal clients.
For the history of these macros, see the investigation:

2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.
On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
cannot cover the memory address (64-bit). `FT_MEM_VAL' is
used for hashing only and not dereferred, so using signed
type FT_PtrDist is safe.
* src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
return value from FT_ULong to FT_PtrDist.
(ft_mem_table_resize): The type of hash is changed to
FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Replace "%lx" for memory address by "%p", LLP64 platforms.
On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
the memory address (64-bit). Also the casts from the pointer
type to long int should be removed to preserve the address
correctly.
* src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
(End_Profile) Ditto.
* src/truetype/ttinterp.c (Init_Context): Ditto.
2010-10-15 Alexei Podtelezhnikov <apodtele@gmail.com>
Fix thinko in spline flattening.
FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL.
* src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and

[raccess] Skip unrequired resource access rules by Darwin VFS.
When a resource fork access rule by Darwin VFS could open the
resource fork but no font is found in it, the rest of rules
by Darwin VFS are skipped. It reduces the warnings of the
deprecated resource fork access method by recent Darwin kernel.
Fix MacPorts ticket #18859:
http://trac.macports.org/ticket/18859
* src/base/ftobjs.c (load_face_in_embedded_rfork):
When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
means that the file is possible to be `fopen'-ed but zero-sized.
Also there is a case that the resource fork is not zero-sized,
but no supported font exists in it. If a rule by Darwin VFS
falls into such cases, there is no need to try other Darwin VFS
rules anymore. Such cases are marked by vfs_rfork_has_no_font.
If it is TRUE, the Darwin VFS rules are skipped.
2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[raccess] Grouping resource access rules based on Darwin VFS.
MacOS X/Darwin kernel supports a few tricky methods to access
a resource fork via ANSI C or POSIX interface. Current resource
fork accessor tries all possible methods to support all kernels.
But if a method could open a resource fork but no font is found,
there is no need to try other methods older than tested method.
To determine whether the rule index is for Darwin VFS, a local
function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
To use this function in ftobjs.c etc but it should be inlined,
it is exposed by ftbase.h.
* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
the rules to access the resource fork.
(raccess_guess_rec): New structure to bind the rule function and
rule enum type.
(FT_Raccess_Guess): The list of the rule functions is replaced by
(raccess_guess_table): This. This is exposed to be used by other
intra module functions.
(raccess_rule_by_darwin_vfs): A function to return a boolean
if the rule specified by the rule index is based on Darwin VFS.
2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Prevent to open a FT_Stream for zero-sized file on non-Unix.
builds/unix/ftsystem.c prevents to open an useless stream from
zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
stream drivers for ANSI C, Amiga and VMS return useless streams.

2010-09-20 Graham Asher <graham.asher@btinternet.com>
David Bevan <david.bevan@pb.com>
[smooth] Fix and improve spline flattening.
This fixes the flattening of cubic, S-shaped curves and speeds up
the handling of both the conic and cubic arcs.
See the discussions on the freetype-devel mailing list in late
August and September 2010 for details.
* src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.

`FT_Long'.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Truncate the element length at the end of the stream.
See Savannah bug #30975.
* src/cff/cffload.c (cff_index_access_element): `off2', the offset
to the next element is truncated at the end of the stream to prevent
invalid I/O. As `off1', the offset to the requested element has
been checked by `FT_STREAM_SEEK', `off2' should be checked
similarly.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Ignore CID > 0xFFFFU.
See Savannah bug #30975.
* src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
greater than 0xFFFFU. CFF font spec does not mention maximum CID in
the font, but PostScript and PDF spec define that maximum CID is
0xFFFFU.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Make trace message in` cff_charset_load' verbose.
See Savannah bug #30975.
* src/cff/cffload.c (cff_charset_load): Report the original `nleft'
and truncated `nleft'.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[cff] Correct `max_cid' from CID array length to max CID.
See Savannah bug #30975.
* src/cff/cffload.c (cff_charset_compute_cids): Don't increment
max_cid after detecting max CID. The array CFF_Charset->cids is
allocated by max_cid + 1.
(cff_charset_cid_to_gindex): Permit CID is less than or equal to
CFF_Charset->max_cid.
* src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is
calculated as CFF_Charset->max_cid + 1.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Sanitize the broken offsets in `loca'.
See Savannah bug #31040.
* src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
offset to the requested entry in `glyf' exceeds the end of the
table, return offset=0, length=0. If `pos2', the offset to the next
entry in `glyf' exceeds the end of the table, truncate the entry
length at the end of `glyf' table.
2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[sfnt] Prevent overrunning in `post' table parser.
See Savannah bug #31040.
* src/sfnt/ttpost.c (load_post_names): Get the length of `post'
table and pass the limit of `post' table to `load_format_20' and
`load_format_25'.
(load_format_20): Stop the parsing when we reached at the limit of
`post' table. If more glyph names are required, they are filled by
NULL names.
2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Don't duplicate size->twilight structure to be freed.
See Savannah bug #31040 for detail.
* src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
FT_GlyphZoneRec size->twilight to be freed. If duplicated,
`FT_FREE' erases the duplicated pointers only and leave original
pointers. They can cause the double-free crash when the burst
errors occur in TrueType interpreter and `free_buffer_in_size' is
invoked repeatedly.
2010-09-15 Werner Lemberg <wl@gnu.org>
Make bytecode debugging with FontForge work again.
* src/truetype/ttinterp.c (TT_RunIns): Don't call
`free_buffer_in_size' in case of error if a debugger is active.
2010-09-14 Werner Lemberg <wl@gnu.org>
Improve tracing messages.
* src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
message.

tracing message.
* src/truetype/ttgload.c (tt_loader_init): Add tracing message.
* src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
glyph doesn't fit into a small bitmap container.
2010-09-13 Werner Lemberg <wl@gnu.org>
Fix minor issues reported by <muktha.narayan@wipro.com>.

* src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
value is already dereferenced.
* src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Ignore the environmental setting of LIBTOOL.
Patch is suggested by Adrian Bunk, to prevent unexpected
reflection of environmental LIBTOOL. See:
http://savannah.nongnu.org/patch/?7290
* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
$(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
by default.
* configure: When configured for the building out of source tee,
FT_LIBTOOL_DIR is set to $(OBJ_DIR).
2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Decrease the trace level catching the interpreter error.
* src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
showing the error when the interpreter returns with an error,
from` FT_TRACE7' to `FT_TRACE1'.
2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
[truetype] Prevent bytecode reuse after the interpretation error.
* src/truetype/ttinterp.c (free_buffer_in_size): New function to
free the buffer allocated during the interpretation of this glyph.
(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
an error occurs in the bytecode interpretation. The interpretation
of invalid bytecode may break the function definitions and referring
them in later interpretation is danger. By unsetting these flags,
`fpgm' and `prep' tables are executed again in next interpretation.
This fixes Savannah bug #30798, reported by Robert Święcki.
2010-08-29 Werner Lemberg <wl@gnu.org>
[ftraster] Pacify compiler.
* src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is
not used.
2010-08-29 Werner Lemberg <wl@gnu.org>
[cff] Allow SIDs >= 65000.
* src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
The threshold for SIDs is not applicable here. I misinterpreted the
`SID values 65000 and above are available for implementation use'
sentence in the CFF specification.
Problem reported by Ivan Ninčić <inincic@pdftron.com>.
2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Force hinting when the font lacks its familyname.
In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
stream may lack `name' table because they are not required. Hinting
for nameless fonts is safer for PDFs including embedded Chinese
fonts. Written by David Bevan, see:
http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html
http://lists.freedesktop.org/archives/poppler/2010-August/006310.html
* src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by
nameless font is given, TRUE is returned to enable hinting.
2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
Register yet another tricky TrueType font.
* src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?',
a Kaishu typeface paired with `HuaTianSongTi?' by Huatian
Information Industry.
2010-08-17 Teijo Kinnunen <Teijo.Kinnunen@nuance.com>
Fix Savannah bug #30788.
* src/cache/ftccache.c (FTC_Cache_Clear): Check `cache->buckets' for
NULL too.
2010-08-10 Werner Lemberg <wl@gnu.org>
Try to fix Savannah bug #30717 (and probably #30719 too).
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Add another

drivers during the face closing process. Type42 faces should be
closed before TrueType faces, because a Type42 face refers to
another internal TrueType face which is created from sfnt[] array on
the memory.
2010-08-06 Yuriy Kaminskiy <yumkam@mail.ru>

Additional fix for Savannah bug #30306.
* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the
POST fragment is 0, the segment is completely ignored. The declared
length of the segment is not cared at all. According to Adobe
Technical Note 5040, type 0 segment is a comment only and should not

2010-05-10 Ken Sharp <ken.sharp@artifex.com>
Fix Savannah bug #29846.
Previously we discovered fonts which used `setcurrentpoint' to set
the initial point of a contour to 0,0. This caused FreeType to
raise an error, because the `setcurrentpoint' operator is only
supposed to be used with the results from an OtherSubr subroutine.
This was fixed by simply ignoring the error and carrying on.
Now we have found a font which uses setcurrentpoint to actually
establish a non-zero point for a contour during the course of a
glyph program. FWIW, these files may be produced by an application
called `Intaglio' on the Mac, when converting TrueType fonts to
Type 1.
The fix allows the new invalid behaviour, the old invalid behaviour
and real proper usage of the operator to work the same way as Adobe
interpreters apparently do.
(t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
two elements of the stack to establish unconditionally the current x
and y coordinates.
Make the `flex' subroutine handling (OtherSubr 0) put the current
x,y coordinates onto the stack, instead of two dummy uninitialised
values.
