* src/pfr/pfrobjs.c (pfr_face_init): detect non-scalable fonts
correctly. fixes bug #17876
* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
correctly. This fixes Savannah bug #17876.
* src/truetype/ttobjs.h, src/truetype/ttobjs.c,
src/truetype/ttgload.c: do not allocate interpreter-specific
tables in memory if we're not going to load glyphs with it
anyway.
Do not allocate interpreter-specific tables in memory if we are not
going to load glyphs with the bytecode interpreter anyway.
* src/truetype/ttgload.c (tt_loader_init): Load execution context
only if glyph is hinted.
Updated.
* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
and `cvs_ready'.
Add `tt_size_ready_bytecode' declaration.
* src/truetype/ttobjs.c (tt_size_done_bytecode,
tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
(tt_size_init): Move most code into `tt_size_init_bytecode'.
(tt_size_done): Move most code into `tt_size_done_bytecode'.
(tt_size_reset): Move some code to `tt_size_ready_bytecode'.
* src/sfnt/ttmtx.c, include/freetype/internal/tttypes.h:
don't extract the metrics table from the SFNT font file.
Instead, reparse it on each glyph load, since the runtime
difference will not be noticeable, and it can save a lot
of heap memory when memory-mapped files are not used.
* src/sfnt/ttcmap.c: slight optimization in the CMAP 4 validator
Don't extract the metrics table from the SFNT font file. Instead,
reparse it on each glyph load. The runtime difference is not
noticeable, and it can save a lot of heap memory when memory-mapped
files are not used.
* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffgload.c,
src/cff/cfftypes.h: formatting + do not load the CFF index
offsets into memory, since this wastes a *lot* of heap memory
with large Asian CFF fonts. There is no significant performance
loss
* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
`horz_metrics_offset' and `vert_metrics_ofset'.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
Updated.
* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
Do not load the CFF index offsets into memory, since this wastes a
*lot* of heap memory with large Asian CFF fonts. There is no
significant performance loss.
* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
`data_size'.
(CFF_CharsetRec): Add field `num_glyphs'.
* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
cff_charset_cid_to_gindex): New functions.
(cff_new_index): Renamed to...
(cff_index_init): This. Update all callers.
Updated -- some code has been moved to `cff_index_load_offsets'.
(cff_done_index): Renamed to...
(cff_index_done): This. Update all callers.
(cff_index_get_pointers, cff_index_access_element): Updated to use
stream offsets.
(cff_charset_compute_cids): Set `num_glyphs' field.
(cff_encoding_load): Updated.
* src/cff/cffgload.c (cff_slot_load): Updated.
