This fixes the flattening of cubic, S-shaped curves and speeds up
the handling of both the conic and cubic arcs.

See the discussions on the freetype-devel mailing list in late
August and September 2010 for details.

suzuki toshiya 73aa20ca1d [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.

suzuki toshiya d2d843a01c [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 about
maximum CID in the font, but PostScript and PDF spec define
that maximum CID is 0xFFFFU.

suzuki toshiya b3e1954d16 [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.

suzuki toshiya 643d49df09 [truetype] Sanitize the broken offsets in `loca'.
* 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.

suzuki toshiya db053ec9a5 [truetype] Don't duplicate size->twilight structure to be freed.
* 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.
2010-09-17 23:20:00 +09:00
Werner Lemberg afd89d309d 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.

* src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
value is already dereferenced.

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.
* configure: When configured for the building out of source tee,
FT_LIBTOOL_DIR is set to $(OBJ_DIR).

suzuki toshiya 0eb657b0aa [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().
2010-08-31 13:29:05 +09:00
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.

Fix Savannah bug #30798, reported by Robert Swiecki.

Werner Lemberg 12cf031644 [ftraster] Pacify compiler.

Werner Lemberg 0e95b3d15c [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.

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:

http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html
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 21:42:28 +09:00
suzuki toshiya 8b05b5d801 Register yet another tricky TrueType font.
* src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?',

Information Industry.
