Werner Lemberg 8312ab7563 * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c. 2009-03-09 13:18:47 +00:00
Werner Lemberg ee3cc2e4fc Fix handling of EBDT formats 8 and 9 (part 2).
This patch fixes the following problems in ttsbit0.c:

. Bitmaps for compound glyphs were never allocated.

. `SBitDecoder' refused to load metrics if some other metrics have
  already been loaded.  This condition certainly makes no sense for
  recursive calls, so I've just disabled it.  Another possibility
  would be resetting `decoder->metrics_loaded' to false before
  loading each composite component.  However, we must restore the
  original metrics after finishing the recursion; otherwise we can
  get a misaligned glyph.

. `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
  causing some glyph components to be shifted too far to the right
  (especially noticeable for small sizes).

Note that support for grayscale bitmaps (not necessarily compound) is
completely broken in ttsbit0.c.

* src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
(tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
of `h == height'.
(tt_sbit_decoder_load_compound): Reset metrics after loading
components.
Allocate bitmap.

Werner Lemberg e5a7cc239c Fix handling of EBDT formats 8 and 9.
The main cycle in `blit_sbit' makes too many iterations: it actually
needs the count of lines in the source bitmap rather than in the
target image.

* src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]:
Add parameter `source_height' and use it for main loop.
