Behdad Esfahbod 7d235d272f Flesh out tt funcs a bit 2011-08-19 19:23:28 +02:00
Behdad Esfahbod b9415e76d7 [API] Add hb_font_set_funcs_data() 2011-08-19 19:20:30 +02:00
Behdad Esfahbod e6c09cdf43 Remove the pre_allocate argument from hb_buffer_create()
For two reasons:

1. User can always call hb_buffer_pre_allocate() themselves, and

2. Now we do a pre_alloc in add_utfX anyway, so the total number of
reallocs is limited to a small number (~3) anyway.  This just makes the
API cleaner.

Behdad Esfahbod 0b7e4d9f20 [ft] FT_Get_Advance() for advance-width callbacks
Using graphite2's comparerenderer suggests that this makes hb-ft 15
times faster.  No caching layer needed anymore.

Behdad Esfahbod 4e9ff1dd6e Pre-allocate buffers when adding string
We do a conservative estimate of the number of characters, but still,
this limits the number of buffer reallocs to a small constant.

Behdad Esfahbod 38b2118724 [API] Add hb_ft_font_set_funcs(), remove hb_ft_get_font_funcs()
Remove hb_ft_get_font_funcs() as it cannot be used by the user anyway.

Add hb_ft_font_set_funcs().  Which will make the font internally use
FreeType.  That is, no need for the font to have created using the
hb-ft API.  Just create using hb_face_create()/hb_font_create() and
then call this on the font (after having set font scale).  This
internally creates an FT_Face and attached to the font.

Behdad Esfahbod 02aeca985b [API] Changes to main shape API
hb_shape() now accepts a shaper_options and a shaper_list argument.
Both can be set to NULL to emulate previous API.  And in most situations
they are expected to be set to NULL.

hb_shape() also returns a boolean for now.  If shaper_list is NULL, the
return value can be ignored.

shaper_options is ignored for now, but otherwise it should be a
NULL-terminated list of strings.

shaper_list is a NULL-terminated list of strings.  Currently recognized
strings are "ot" for native OpenType Layout implementation, "uniscribe"
for the Uniscribe backend, and "fallback" for the non-complex backend
(that will be implemented shortly).  The fallback backend never fails.

The env var HB_SHAPER_LIST is also parsed and honored.  It's a
colon-separated list of shaper names.  The fallback shaper is invoked if
none of the env-listed shapers succeed.

New API hb_buffer_guess_properties() added.
