||
[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.

[gxvalid] Cleanup.
|

Some invalid, overrunning, unrecommended non-zero values

FT_INVALID_xxx;

[truetype] Always check the checksum to identify tricky fonts.

Always ignore global advance.

This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,

[autofit] Blur CJK stems if too many to preserve their gaps.
|

When there are too many stems to preserve their gaps in the

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

This catches a rendering problem with glyph `x' from Tahoma at

from 2009-06-11 makes a larger jitter value unnecessary.

[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.

[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:
|
||

|
||
|
||
* 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.
|

|
||
[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'.

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
|

[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.

[raccess] Skip unrequired resource access rules by Darwin VFS.
|
||
|
||
When a resource fork access rule by Darwin VFS could open the

|
||
by Darwin VFS are skipped. It reduces the warnings of the

||
deprecated resource fork access method by recent Darwin kernel.

|
||
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.

|

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.

Minor fixes.
|
||
|
||
* src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'

|
||
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.
|
||
* 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.
|
||
* 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).
|
||

|
||
|
||
[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>.

|
||
|
||
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.
|
||
|

a Kaishu typeface paired with `HuaTianSongTi?' by Huatian
|
||
Information Industry.

Point numbers for FreeType's implementation of hinting masks are
|
||
collected before the final number of points of a glyph has been
|
||
determined; in particular, the code for handling the `endchar'
|
||
opcode can reduce the number of points.
|
||
|
||
* src/pshinter/pshalgo.c (psh_glyph_find_strong_points): Assure that
|
||
`end_point' is not larger than `glyph->num_points'.

|
||
|
||
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.
