name.
(StringTable) <dump>: Don't pass master table name.
(StringTable) <dump_sublist>: Emit explanatory comment.
Simplify and make output more human readable.

David Turner
12e51f1685 * src/tools/glnames.py: rewrote the generator for the 'pstables.h'
header, which contains various constant tables related to glyph
    names. It now uses a different storage scheme that saves about 20
    Kb and closes bug #12262

  * src/psnames/psmodule.c: rewrote some parts to comply with recent
    changes in 'pstables.h'

fa0eb0c95f * src/sfnt/ttkern.c (tt_face_load_kern): fixing a small bug which returned
invalid (random) values for the horizontal kerning

e5680279b2 * many, many files: several memory optimizations were implemented to
drastically reduce the heap usage of FreeType, especially in the case
  of memory-mapped files. The idea is to avoid loading and decoding tables
  in the heap, and instead access the raw data whenever possible (i.e.
  when it doesn't compromise performance).

  This had several impacts: first, opening vera.ttf uses a ridiculous amount
  of memory (when the FT_Library footprint is accounted for), until you start
  loading glyphs. Even then, you'll save at least 20 Kb compared to the non
  optimized case. performance of various operations, including open/close
  has also been dramatically improved.

  More optimisations to come. The auto-hinter eats memory like crazy? This
  must be stopped...
2005-02-26 00:12:04 +00:00
David Turner
e70d553111 * include/freetype/config/ftoption.h, include/freetype/internal/ttypes.h,
src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c:
    added the temporary configuration FT_OPTIMIZE_MEMORY to control various
    optimizations used to reduce the heap footprint of memory-mapped TrueType
    files.

    * src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,
    tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table
    is read directly from memory-mapped streams, instead of being decoded
    into the heap.

    * src/truetype/ttpload.c: only load the CVT and fpgm tables when the
    bytecode interpreter is compiled in.
2005-02-22 16:53:06 +00:00
David Turner
3e26d07e60 * src/base/ftdbgmem.c: adding the ability to list all allocation sites
in the memory debugger. Also a new function FT_DumpMemory() was added.
	It is only available in builds with FT_DEBUG_MEMORY defined, and you
	must declare it in your own code to use it, i.e. with something
	like:

	  extern void FT_DumpMemory( FT_Memory );

	  ...

	  FT_DumpMemory( memory );

	* include/freetype/config/ftoptions.h: disabling TrueType bytecode
	interpreter !

	* include/freetype/internal/ftmemory.h: adding FT_ARRAY_ZERO, as a
	convenience macro.
