Kan-Ru Chen 21b1a0de7c 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...
(FT_Stream_GetU*): Functions which read unsigned integers.
Update all macros accordingly.

* src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.

Werner Lemberg d6a213f8ea [truetype] Improve handling of invalid references.
* src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
error codes only if pedantic hinting is active.  At the same time,
try to provide sane values which hopefully allow useful
continuation.  Exception to this is CALL and LOOPCALL – due to
possible stack corruption it is necessary to bail out.

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

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

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().
2011-01-09 20:31:22 +09:00
suzuki toshiya 34f4b20a15 Update Jamfile to include Bzip2 support.
* Jamfile: Include src/bzip2 to project.
Comments for lzw, gzip, bzip2 are changed to clarify that
they are for compressed PCF fonts, not others.
(e.g. compressed BDF fonts are not supported yet)
2011-01-06 11:19:50 +09:00
suzuki toshiya 55e6a6fadf Update Symbian project files 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.

* builds/symbian/bld.inf: Include ftbzip2.h.
* builds/symbian/freetype.mmp: Include ftbzip2.c.

suzuki toshiya 017b4d5e7f Update classic MacOS 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.

* builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o.
* builds/mac/FreeType.m68k_far.make.txt: Ditto.
* builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x.

2011-01-06 02:49:52 +09:00
suzuki toshiya be683e7597 Update Amiga makefiles to include Bzip2 support.
Currently, it provides FT_Stream_OpenBzip2() that returns

error for the applications designed for Unix systems.

* builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c.
* builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c.
* builds/amiga/smakefile: Ditto.

suzuki toshiya 41d7e4a6ed 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.
2011-01-06 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.

suzuki toshiya 3512a71269 [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

* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.

suzuki toshiya b8b498f2e2 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.

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.

suzuki toshiya 463dddadfb [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 17:20:27 +09:00
suzuki toshiya c081a4a932 [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.

suzuki toshiya 4b71871418 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.

suzuki toshiya fd0cdb7b9e 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.

(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.

suzuki toshiya 0eb9b1f571 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:
