Werner Lemberg dcdb3167dc [truetype] Fix handling of MIRP instruction.
Thanks to Greg Hitchcock who explained the issue.

* src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
`>' since the description in the specification is incorrect.
This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
65 medium' at 15ppem.
2011-01-18 07:35:26 +01:00
suzuki toshiya 17f54bc66c Fix ARM assembly code in include/freetype/config/ftconfig.h.
* include/freetype/config/ftconfig.h (FT_MulFix_arm):
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.

Werner Lemberg 21bdca7907 [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.

suzuki toshiya a2ef6647ae 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 13:33:28 +09:00
suzuki toshiya c68a82d8fc 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.

Werner Lemberg c02485cb72 [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 21:55:08 +01:00
Werner Lemberg 29bc310563 [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.

suzuki toshiya 5e7ad208e3 [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 functon 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:
38b272ffbb

* 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 23:09:36 +09:00
suzuki toshiya 38b272ffbb [cache] Notice if a cache query induced the node list change.
Some node comparators (comparing the cache node content 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 the change 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 22:52:24 +09:00
suzuki toshiya 62d116f8d6 [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 22:38:10 +09:00
suzuki toshiya 9a2e255b23 [cache] Deduplicate the code to get the top node by a hash.
There are several duplicated codes 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 deduplicate them, a cpp-macro to do same work
FTC_NODE__TOP_FOR_HASH( cache, hash ) is introduced.
For non-inlined config, 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 21:09:58 +09:00
suzuki toshiya 52a1e47a5c [cache] inline-specific functions are conditionalized.
* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized
for inlined config.  This function is a thin wrapper of
ftc_gnode_compare() for inlined FTC_CACHE_LOOKUP_CMP()
(see `nodecmp' argument).  Under non-inlined config,
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 20:49:21 +09:00
suzuki toshiya 0de5b376d7 [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 02:36:50 +09:00
suzuki toshiya 1909959973 * 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.

Harsha 7774ac67ec Apply Savannah patch #7422.
If we encouter 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 20:17:26 +01:00
Werner Lemberg 396b11b840 [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
on the stack.
