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 e891e4d6f1 [UVS] Stabilizes UVS supporting functions against non-UVS fonts.
UVS supporting functions assume the variation handler functions
are valid.  When a font without cmap format 14 is given, these
function pointers are left as NULL, so calling these functions
causes NULL pointer dereference.

2010-10-25 15:43:01 +09:00
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
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_UInt32 for better pointer calculation.

suzuki toshiya 61590b73d1 [cache] Hide internal macros incompatible with LLP64.

normal clients.

2010-10-25 01:12:09 +09:00
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.
2010-10-25 00:35:59 +09:00
suzuki toshiya 46c371c2c7 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.

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.

* 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.

suzuki toshiya 900e7e0cde [sfnt] Prevent overrunning in `post' table parser.
* 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.  See Savannah bug #31040.

* 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.  See Savannah bug #31040 for detail.

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.

suzuki toshiya 29e044a4af [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.

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:

Ken Sharp 88169b107a 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.

Ken Sharp 980b76ea5e Really fix Savannah bug #28678 (part 1).
After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only.  For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction.  Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).

* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.

it directly.  The supplied patch removed the block of code which
checked this usage entirely.

This turns out to be a Bad Thing.  If `setcurrentpoint' is being
used correctly it should reset the flex flag in the decoder.  If we
don't do this then the flag never gets reset and we omit any further
contours from the glyph (at least until we close the path or
similar).

Ken Sharp ce41259372 Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
This fixes Savannah bug #28226.

At least two wild PostScript files of unknown provenance contain
Type 1 fonts, apparently converted from TrueType fonts in earlier
PDF versions of the files, which use the `setcurrentpoint' operator
inappropriately.

FreeType currently throws an error in this case, but Ghostscript and
Adobe Distiller both accept the fonts and ignore the problem.  This
commit #ifdefs out the check so PostScript interpreters using
FreeType can render these files.

The specification says `setcurrentpoint' should only be used to set
the point after a `Subr' call, but these fonts use it to set the
initial point to (0,0).  Unnecessarily so, as they correctly use an
`hsbw' operation which implicitly sets the initial point.

Bram Tassyns 4694ea2b95 Improve vertical metrics calculation (Savannah bug #27364).
The calculation of `vertBearingX' is not defined in the OTF font
spec so FreeType does a `best effort' attempt.  However, this value
is defined in the PDF and PostScript specs, and that algorithm is
better than the one FreeType currently uses:

  FreeType: Use the middle of the bounding box as the X coordinate
            of the vertical origin.

  Adobe PDF spec: Use the middle of the horizontal advance vector as
                  the X coordinate of the vertical origin.

FreeType's algorithm goes wrong if you have a really small glyph
(like the full-width, circle-like dot at the end of the sentence, as
used in CJK scripts) with large bearings.  With the FreeType
algorithm this dot gets centered on the baseline; with the PDF
algorithm it gets the correct location (in the top right).  Note
that this is a serious issue, it's like printing the dot at the end
of a Roman sentence at the center of the textline instead of on the
baseline like it should. So i believe the PDF spec's algorithm
should be used in FreeType as well.

The `vertBearingY' value for such small glyphs is also very strange
if no `vmtx' information is present, since the height of the bbox is
not representable for the height of the glyph visually (the
whitespace up to the baseline is part of the glyph).  The fix also
includes some code for a better estimate of `vertBearingY'.

* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
is now calculated as described by the Adobe PDF Spec.  Estimate for
`vertBearingY' now works better for small glyphs completely above or
below the baseline into account.

* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
calculated as described by the Adobe PDF Spec.  Vertical metrics
information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
was not defined.

* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
now calculated as described by the Adobe PDF Spec.
