|
||
|
||
[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

[truetype] Register a set of tricky fonts, NEC FA family.
|
||
|
||
* src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids):
|
||
Add 8 checksum sets for NEC FA family. For the tricky fonts
|
||
without some tables (e.g. NEC FA fonts lack cvt table),
|

extra check is added to assure that 0-length table in the

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.

||
|
||

|
||
|
||
[autofit] Add more Indic scripts with hanging baseline.
|
||
|
||
* src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu,
|
||
Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are
|
||
added.
|
||
|
||
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),
|
||
src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
|
||
tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
|

src/truetype/ttgload.h: Implement it.
|
||
|
||
* docs/CHANGES: Updated.

|
||
[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.
|
||
|
||
2011-04-18 Werner Lemberg <wl@gnu.org>
|
||
|
||
Integrate autofitter debugging stuff.
|
||
|
||
* devel/ftoption.h, include/freetype/config/ftoption.h
|

||
|
||
* include/freetype/internal/fttrace.h: Add trace components for
|
||
autofitter.
|

|
||
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.
|
||
|
||
* include/freetype/internal/ftstream.h, src/base/ftstream.c
|
||
(FT_Stream_Get*): Replace with...
|
||

`orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
|

[raster] Make bbox handling the same as with Microsoft's rasterizer.
|
||
|
||
Right before B/W rasterizing, the bbox gets simply rounded to
|

Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
|
||
|
||
* builds/unix/configure.raw: Consider recent gcc-standard

[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.

|
||
[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'.

SYSTEM_ZLIB is used to switch the builtin zlib source

|
||
|
||
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.

[UVS] Fix `find_variant_selector_charmap', Savannah bug #31545.
|
||
|
||
Since 2010-07-04, `find_variant_selector_charmap' returns
|
||
the first cmap subtable always under rogue-compatible
|
||
configuration, it causes NULL pointer dereference and
|
||
make UVS-related functions crashed.

* src/base/ftobjs.c (Fix find_variant_selector_charmap):
|
||
Returns UVS cmap correctly.

[ftsmooth] Improve rendering.
|
||
|
||
* src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
|

cubic deviations have been estimated _after_ UPSCALE, whereas
|
||
conic ones have been evaluated _before_ UPSCALE, which produces
|

inferior rendering results. Fix this.

[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.

* 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.

[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.

|
||
|
||
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.

[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.

|
||
[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.

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.
|
||
For cross-platform consistency, all stream drivers should act
|
||
same.
|
||
|
||
* src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
|
||
file is zero, FT_Err_Cannot_Open_Stream is returned.
|
||
* builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.

||
Improve tracing messages.
|
||
|
||
* src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
|
||
message.
|
||
* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
|
||
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/autofit/aflatin.c (af_latin_compute_stem_width): Remove
|
||
redundant conditional check.
|
||
* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
|
||
* src/cff/cffload.c (cff_encoding_load): Remove conditional check
|
||
which always evaluates to `true'.
|
||
* src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
|
||
Ditto.
|
||
* src/truetype/ttinterp.c (Ins_IUP): Ditto.
|
||

|
||
|
||
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).

|
||
|
||
[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>
|

|
||
|
||
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.
|
||
|
||

|
||
|
||
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.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.

Information Industry.

|
||
|
||
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.
