David Turner 92f30c812c * src/base/ftobjs.c (FT_Open_Face): don't call FT_New_GlyphSlot and

David Turner ad20e6ba57 * src/base/Jamfile: fixing broken Jamfile 2005-09-22 20:37:51 +00:00
Werner Lemberg 8eacad6daa * freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a 
font to have no `head' table if tables `SING' and `META' are
present; this is to support `SING Glyphlet'.

`SING Glyphlet' is an extension to OpenType developed by Adobe
primarily to facilitate adding supplemental glyphs to an OpenType
font (with emphasis on, but not necessariy limited to, gaiji to a
CJK font).  A SING Glyphlet Font is an OpenType font that contains
the outline(s), either in a `glyf' or `CFF' table, for a glyph;
`cmap', `BASE', and `GSUB' tables are present with the same format
and functionaliy as a regular OpenType font; there are no `name',
`head', `OS/2', and `post' tables; there are two new tables, `SING'
which contains details about the glyphlet, and `META' which contains
metadata.

Further information on the SING Glyphlet format can be found at:

  http://www.adobe.com/products/indesign/sing_gaiji.html

* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New
macros for the OpenType tables `SING' and `META'.  These two tables
are used in SING Glyphlet Format fonts.

Werner Lemberg 2752bd1a46 * src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline 
to (0,0) if bit 1 of the `head' table isn't set.  This improves
rendering of buggy fonts.
 2005-08-22 07:11:31 +00:00
Wu, Chia-I (吳佳一) 15c1f5d36f * src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of

* src/truetype/ttobjs.c (tt_driver_init): Initialize execution context
here.

glyph loader. We then use it directly, instead of face's glyph loader,
when loading glyph.

* src/truetype/ttdriver.c: Use tt_slot_init for glyph slot
initialization.
(TT_Load_Glyph): Load flag dependencies are handled here.
Return error if size is NULL.

No need to save/restore loader->stream before/after
TT_Vary_Get_Glyph_Deltas now.
(TT_LOADER_SET_PP): New macro to calculate and set the four phantom points.
(TT_Process_Composite_Component, TT_Process_Composite_Glyph,
load_truetype_glyph): Refactor load_truetype_glyph into these three functions.
Never set exec->glyphSize to 0. (close #13107)
Forget glyph frame before calling TT_Process_Simple_Glyph.
(TT_Load_Glyph, load_sbit_image, tt_loader_init): Refactor TT_Load_Glyph into
these three functions.
Set various fields of `glyph' here, instead of in load_truetype_glyph
and compute_glyph_metrics.
 2005-08-16 01:54:59 +00:00
Werner Lemberg f20a4d3527 * docs/INSTALL.ANY: Updated. 2005-08-10 13:24:51 +00:00

(tt_glyphzone_new): Allocate right size of arrays.
Set max_points and max_contours properly.
 2005-07-31 11:41:54 +00:00
Wu, Chia-I (吳佳一) 2a41ab9e88 * src/truetype/ttdriver.c (Set_Char_Sizes): Avoid unnecessary
