Werner Lemberg 4af3c4d7ee Add many checks to protect against malformed PCF files.
* src/pcf/pcfdrivr.c (PCF_Face_Done): Protect against NULL pointers.
(PCF_Face_Init): Add calls to PCF_Face_Done in case of errors.

* src/pcf/pcfread.c (pcf_read_TOC): Protect against malformed table
data and check that tables don't overlap (using a simple
bubblesort).
(PCF_METRIC_SIZE, PCF_COMPRESSED_METRIC_SIZE, PCF_PROPERTY_SIZE):
New macros which give the size of data structures in the data
stream.
(pcf_get_properties): Use rough estimates to get array size limits.
Assign `face->nprops' and `face->properties' earlier so that a call
to PCF_Face_Done can do the clean-up in case of error.
Protect against invalid string offsets.
(pcf_get_metrics): Clean up code.
Adjust tracing message levels.
Use rough estimate to get array size limit.
(pcf_get_bitmaps): Clean up code.
Adjust tracing message levels.
Use rough estimates to get offset limits.
(pcf_get_encodings): Adjust tracing message level.
(pcf_get_accel): Clean up code.

don't have a POINT_SIZE property.  This fixes Savannah bug #16914.

Werner Lemberg 24703f8b39 * src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15.
(t1_decoder_parse_charstrings): Operator with
opcode 15 pops its two arguments.
Handle the case where the pops of an othersubr may be part of a
subroutine.
Handle unknown othersubrs gracefully: count their operands and let
the following pop operators push the operands as the results onto
the Type1 stack.
Improve handling of setcurrentpoint opcode.

Werner Lemberg e9a746674a Fix handling of self-delimiting tokens. 2006-06-26 17:37:44 +00:00
Werner Lemberg c011f4cba1 The Type 1 parser now skips over top-level procedures as required
for a `Simplified Parser'.  This makes the parser more robust as it
doesn't poke around in PostScript code.  Additionally, it makes the
FontDirectory hackery in src/type1/t1load.c unnecessary.

* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
(skip_literal_string): Add FT_Error as return value.
Handle escapes better.
(skip_string): Add FT_Error as return value.
Don't set `parser->error' but return error code directly.
(skip_procedure): New function.
(ps_parser_skip_PS_token): Handle procedures.
Update code.
(ps_parser_to_token): Update code.
(ps_parser_load_field_table): Handle bbox entries also.

* src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
Add commented-out code for synthetic fonts.

* include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add
`first_point' member.

* src/truetype/ttgload.c (tt_prepare_zone): Initialize
`first_point'.
(TT_Process_Composite_Glyph): Always untouch points.

* src/truetype/ttinterp.c (Ins_SHC): Fix computation of
`first_point' and `last_point' in case of composite glyphs.
(Ins_IUP): Fix computation of `end_point'.

        leak described in bug #16759.

        We change 'ps_unicodes_init' so that it also takes a 'free_glyph_name'
        callback to release the glyph names returned by 'get_glyph_name'

David Turner 0971735dce * src/pfr/pfrobjs.c (pfr_face_init): fix the computation

  guarantee that glyph index 0 corresponds to the "missing
  glyph"

David Turner 281679de85 * include/freetype/internal/tttypes.h, src/autofit/afangles.c,
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
        src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

David Turner dc3ff31c3f * src/ftccmap.c (FTC_CMapCache_Lookup): changed the threshold

        some segmentation faults with fonts like KozMinProVI-Regular.otf
        which comes from the Japanese Adobe Reader Asian Font pack.
