Werner Lemberg a4d6a1c8d1 Move creation of field `buildchar' of T1_DecoderRec out of

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.

Update code.

(ps_parser_load_field_table): Handle bbox entries also.

    be exported for rogue clients

    even-ness of 'num_blue_values'. Also change the CFF loader so that
    invalid entries in index files are ignored.

`expansion_factor'.

* src/pshinter/pshglob (psh_blues_scale_zones): Fix computation
of blues->no_overshoots -- `blues_scale' is stored with a
magnification of 1000, and `scale' returns fractional pixels.

face->cid_stream so that we can deallocate it safely.


Make the PS parser more tolerant w.r.t. non-standard font data.  In
general, an error is only reported in case of a syntax error; a
wrong type is now simply ignored (if possible).  To be independent
of the order of various MM-specific keywords, the parse_shared_dict
routine has been removed -- the PS parser is now capable to skip
this data.  It no longer fails on parsing e.g.

  dup /WeightVector exch def

Since the token following /WeightVector isn't `[' (starting an
array) it is simply ignored.

* include/freetype/fterrdef.h: Define `FT_Err_Ignore' (0xA2) as a
new internal error value.

* src/type1/t1load.c (parse_blend_axis_types,
parse_blend_design_positions, parse_blend_design_map): Return
T1_Err_Ignore if no proper array is following the keyword.
(parse_weight_vector): Use T1_ToTokenArray, initializing `blend'
structure, if necessary.
Return T1_Err_Ignore if no proper array is following the keyword.
(parse_shared_dict): Removed.
(parse_encoding): Set parser->root.error to return T1_Err_Ignore
if no result can be obtained.
Check for errors before accessing `elements' array.
(t1_keywords): Remove /shareddict.
(parse_dict): Reset error if t1_load_keyword returns T1_Err_Ignore.
Set keyword_flag only in case of success.
Check error code if skipping an unrecognized token.
(T1_Open_Face) [!T1_CONFIG_OPTION_NO_MM_SUPPORT]: Call T1_Done_Blend
if blend commands haven't set up a proper MM font.

* src/psaux/psobjs.c (ps_parser_load_field_table): Remove special
code for synthetic fonts.
Return PSaux_Err_Ignore if no proper value has been found.
2004-02-12 08:33:20 +00:00
Werner Lemberg 0a84eba8a6 * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP):
Initialize `node'.

2004-02-05 14:36:43 +00:00
Werner Lemberg 6b3d00e1a0 * src/type1/t1load.c (parse_dict): Handle `RD' and `-|' commands
outside of /Subrs or /CharStrings.  This can happen if there is
additional code manipulating those two arrays so that FreeType
doesn't recognize them properly.
(T1_Open_Face): Improve an error message.

Remove CR/LF on many files.
2004-02-03 21:34:29 +00:00
Werner Lemberg cf7d908c48 * src/type1/t1load.c (parse_charstrings): Exit immediately if
there are no elements in /CharStrings.  This is needed for fonts
like Optima-Oblique which not only define /CharStrings but access it
also.
2004-02-02 19:41:09 +00:00
Werner Lemberg 5972e9abf8 * src/cff/cffgload.c (cff_operator_seac): Fix magnitude of

(cff_decoder_parse_charstrings) <cff_op_endchar>: Fix magnitude
of accent offset.
Don't hint glyphs twice if seac is emulated.
<cff_op_flex>: Assign correct point tags.
* docs/CHANGES: Updated.

* src/type1/t1parse.c (T1_Get_Private_Dict): Use FT_MEM_MOVE, not
FT_MEM_COPY, for copying the private dict.

* src/type1/t1load.c (parse_subrs): Assign number of subrs only
in first run.
(parse_charstrings): Parse /CharStrings in second run without
assigning values.
(parse_dict): Skip all /CharStrings arrays but the first.  We need
this for non-standard fonts like `Optima' which have different
outlines depending on the resolution.  Note that there is no
guarantee that we get fitting /Subrs and /CharStrings arrays; this
can only be done by a real PS interpreter.
2004-02-01 00:49:56 +00:00
Werner Lemberg 63abb4bc63 * src/type1/t1load.c (parse_dict): Stop parsing if `eexec' keyword

Initialize charset->cids if `invert' is set.
(cff_font_load): In call to cff_charset_load, set `invert' to true
for CID-keyed fonts.
* src/cff/cffgload.c (cff_slot_load): Handle glyph index as CID
and map it to the real glyph index.

* docs/CHANGES: Updated.
2003-12-12 15:38:39 +00:00
Werner Lemberg 4795b36cf9 * src/type1/t1load.c (parse_encoding): Handle `/Encoding [ ... ]'.

checking while parsing.

* docs/CHANGES: Updated.
2003-10-23 16:24:10 +00:00
Werner Lemberg e3f41982a2 Completely revised Type 42 parser. It now handles both fonts
produced with ttftot42 (tested version 0.3.1) and
TrueTypeToType42.ps (tested version May 2001; it is necessary to
fix the broken header comment to be `%!PS-TrueTypeFont...').

from psaux.
Handle `/Encoding [ ... ]' also.
(T42_Load_Status): New enumeration.
(t42_parse_sfnts): Updated to use new PostScript parser routines
from psaux.
(t42_parse_charstrings): Updated to use new PostScript parser
routines from psaux.
Handle `/CharStrings << ... >>' also.
Don't expect that /.notdef is the first element in dictionary.  Copy
code from type1 module to handle this.
(t42_parse_dict): Updated to use new PostScript parser routines
from psaux.
Remove code for synthetic fonts (which can't occur in Type 42
fonts).
(t42_loader_done): Release `swap_table'.

* src/psaux/psobjs.c (skip_string): Increase `cur' properly.

* src/type1/t1load.c (parse_charstrings): Make test for `.notdef'

David Turner e0ec6b3d53 * src/type1/t1load.c (T1_Open_Face): fixed the code to make it handle

   will ignore stem quantization only when FT_LOAD_TARGET_SMOOTH is used

   * src/base/ftobjs.c: changed the default computations to include rounding
   in all cases, this is required to provide accurate kerning data when
   native TrueType hinting is enabled.

   * src/type1/t1load.c: the Type 1 loader now accepts more general names
   according to the Postscript spec (the previous one was too restrictive)
