Suzuki, Toshiya (鈴木俊哉) b1c36cfbd9 * builds/unix/configure.raw: Copy -isysroot option from CFLAGS to LDFLAGS, if required 2008-06-22 15:32:56 +00:00
Werner Lemberg 5df5dbb722 Enable access to the various dropout rules of the B&W rasterizer.
Pass dropout rules from the TT bytecode interpreter to the
rasterizer; temporarily this is enabled only if
`USE_SCAN_CONVERSION_RULES' is defined.

* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.

* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
OpenType specification.
Fix mode 4 computation.
(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

* src/truetype/ttgload.c (TT_Load_Glyph)
[USE_SCAN_CONVERSION_RULES]: Convert scan conversion mode to
FT_OUTLINE_XXX flags.

* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

Werner Lemberg c91dfa39e8 Improve documentation of gray-level rastering and what to do if you need
less than 256 gray levels.

Werner Lemberg 5b631d894c * src/cff/cffobjs.c (cff_face_init): Compute final
`dict->units_per_em' value before assigning it to
`cffface->units_per_EM'.  Otherwise, CFFs without subfonts are be
scaled incorrectly if the font matrix is non-standard.  This fixes
Savannah bug #23630.

* docs/CHANGES: Updated.

Werner Lemberg c94fa6699c * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
original, unscaled input values.  Confirmed by Greg Hitchcock from
Microsoft.

Werner Lemberg ffa496574a * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
of the graphics state for subglyphs to...
(TT_Hint_Glyph): This function.
Hinting instructions for a composite glyph apparently refer to the
just hinted subglyphs, not the unhinted, unscaled outline.  This
seems to fix Savannah bugs #20973 and (at least partially) #23310.
2008-05-25 12:43:57 +00:00
Werner Lemberg c938131856 * src/raster/ftraster.c (fc_black_render): Return 0 when we are

Werner Lemberg 5e8a368673 * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
correction for pixel boundary.  Without this patch, the effect can
be cumulative under certain circumstances, making glyphs taller and
taller after each call.  This fixes Savannah bug #19976.
2008-05-18 21:49:02 +00:00
Werner Lemberg 16dc51feae * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.

	ft_wgl_extra_glyph_name_offsets, ps_check_wgl_name and
	ps_check_wgl_unicode
2008-05-18 14:08:57 +00:00

ft_wgl_extra_glyph_name_offsets): New arrays.
(ps_check_wgl_name, ps_check_wgl_unicode): New functions.
(ps_unicodes_init): Use them to add additional Unicode mappings.

Werner Lemberg bcc750e511 * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
<op_closepath>: `closepath' without a path is a no-op, not an error
(cf. the PS reference manual).

Reported by Martin McBride.

Werner Lemberg bcfcc71d29 * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated. 2008-05-15 09:14:39 +00:00

Werner Lemberg 504645ed5b * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
which contain a single but empty entry.  This is technically
invalid (since it must end with `return', but...)

Reported by Martin McBride.

Werner Lemberg e6e6eade04 Finish fix of scaling bug of CID-keyed CFF subfonts.
* include/freetype/internal/ftcalc.h, src/base/ftcalc.c
(FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
functions.

* src/cff/cffobjs.h (CFF_Internal): New struct.  It is used to
provide global hinting data for both the top-font and all subfonts
(with proper scaling).

* src/cff/cffobjs.c (cff_make_private_dict): New function, using
code from `cff_size_init'.
(cff_size_init, cff_size_done, cff_size_select, cff_size_request):
Use CFF_Internal and handle subfonts.
(cff_face_init): Handle top-dict and subfont matrices correctly;
apply some heuristic in case of unlikely matrix concatenation
results.  This has been discussed with people from Adobe (thanks
goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
and not correct.

* src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.

* src/cff/cffgload.c (cff_builder_init): Updated.
(cff_decoder_prepare): Handle hints globals for subfonts.
Update all callers.
(cff_slot_load): Handling scaling of subfonts properly.

* src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.
(cff_parse_font_matrix): Use it.

* src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em'
FT_ULong.

* docs/CHANGES: Document it.

Werner Lemberg 551dd3c0a6 First steps to fix the scaling bug of CID-keyed CFF subfonts,
reported by Ding Li on 2008/03/28 on freetype-devel.

* src/base/cff/cffparse.c (power_tens): New array.
(cff_parse_real): Rewritten to introduce a fourth parameter which
returns the `scaling' of the real number so that we have no
precision loss.  This is not used yet.
Update all callers.
(cff_parse_fixed_thousand): Replace with...
(cff_parse_fixed_scaled): This function.  Update all callers.
