David Turner 28534d616b * include/freetype/ftadvanc.h, src/base/ftadvanc.c,
include/freetype/config/ftheader.h, include/freetype/freetype.h,
    src/base/Jamfile, src/base/rules.mk, src/cff/cffdrivr.c,
    src/cff/cffgload.c, src/cff/cffgload.h, src/truetype/ttdriver.c,

    src/type1/t1gload.h, src/type1/t1gload.c:
    Add a new header named FT_ADVANCES_H declaring some new APIs
    to extract the advances of one or more glyphs without necessarily
    loading their outlines. Also provide 'fast loaders' for the
    TrueType, Type1 and CFF font drivers (more to come later)

    * autogen.sh: add checks for minimum version of the 'autotools'
    stuff.
2008-09-01 21:35:21 +00:00
Werner Lemberg 6b19e095be * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
where num_locations < num_glyphs.  Problem reported by Ding Li.
2008-07-09 06:20:12 +00:00
Werner Lemberg ce8853af81 * src/truetype/ttinterp. (Ins_SCANTYPE): Don't check rendering mode.
* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
Draw_Sweep): No-dropout mode is value 2, not value 0.
(Draw_Sweep): Really skip dropout handling for no-dropout mode.
2008-06-24 11:19:03 +00:00
Werner Lemberg 745a4f42a5 * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
with IS_HINTED.

* docs/CHANGES: Updated.
2008-06-22 22:41:24 +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.
2008-06-22 13:40:08 +00:00
Werner Lemberg 7cb9ec0f1c * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
`private_len' unsigned.

* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
it as such.

for sane value.
Fix typo.


* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.


* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
`last_point'.


* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
`maxTwilightPoints'.
2008-06-09 20:49:29 +00:00
Werner Lemberg d77e72295e * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
correctly.  This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
2008-06-05 22:07:19 +00:00
Werner Lemberg 2b0b4221ab Cosmetic code changes. 2008-05-28 22:17:28 +00:00
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 89d64fa6e3 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour

(ps_unicodes_init): Use them to add additional Unicode mappings.

2008-03-13 06:38:37 +00:00

from Savannah bug #22356.
2008-02-18 20:34:42 +00:00
Werner Lemberg bf391cb858 * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
where the number of contours in a simple glyph is zero (and which
does contain an entry in the `glyf' table).  This fixes Savannah bug
#21990.
2008-01-10 08:47:08 +00:00
Werner Lemberg bd7e1c3ce0 Pass options from one configure script to another as-is (not
expanded).  This is needed for options like
--includedir='${prefix}/include'.

* builds/unix/detect.mk, configure: Prevent argument expansion in
call to the (real) `configure' script.



* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
TT_USE_BYTECODE_INTERPRETER isn't defined.



There exist CFFs which contain opcodes for the Type 1 operators
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
However, it doesn't harm to support them.

* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
`cff_op_closepath.'
(cff_argument_counts): Ditto.

(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
and 13 (hsbw) which are invalid in Type 2 charstrings.
2007-12-06 17:17:30 +00:00
Werner Lemberg d496b92659 * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
concatenate error codes.

Werner Lemberg 0f6f367ec1 Better maxComponentDepth test. 2007-07-04 19:57:45 +00:00
Werner Lemberg 3033f4366b * src/truetype/ttgload.c (load_truetype_glyph): Always allow a
recursion depth of 1.  This was the maximum value in TrueType 1.0,
and some older fonts don't set this field correctly.

* src/gxvalid/gxvmort1.c
(gxv_mort_subtable_type1_substTable_validate): Fix tracing message.
2007-07-04 14:12:19 +00:00

of bytecode-hinted text. Werner, feel free to package 2.3.5 now :-)
2007-07-01 09:34:04 +00:00

gets rid of Valgrind fixes.

	of degenerate fonts.

Werner Lemberg e12ed563d6 * src/tools/ftrandom.c (font_size): New global variable.
(TestFace): Use it.
(main): Handle new option `--size' to set `font_size'.
(Usage): Updated.
