David Turner d4b4ccb8b3 * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
improvements to the memory debugger to report more information in
	case of errors. Also, some allocations that occured through
	REALLOC couldn't be previously catched correctly..
2001-10-24 08:04:00 +00:00
David Turner 864a36ad78 replaced liberal uses of "memset" by the "MEM_Set" macro call
(some platforms don't provide this ANSI function !!)

some changes to "ftsystem.c" implementations in order to use
the new memory debugger on Unix, VMS and Amiga too !!

David Turner c1b7ca25b8 * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: modified
the debugging memory manager to report the location (source file name
        + line number) where leaked memory blocks are allocated in the source
        file..  funny, isn't it ??
2001-10-22 14:50:41 +00:00
David Turner 9cd8c10950 Added a new debugging memory manager implementation. See the
FT_DEBUG_MEMORY macro definition in "ftoption.h", as well as the
file "src/base/ftdbgmem.c"

Werner Lemberg 6a36a6db05 Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables.  This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).

* src/tools/glnames.py (mac_standard_names): Fixed.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.
(the_adobe_glyph_list): Renamed to ...
(adobe_glyph_names): This.
(the_adobe_glyphs): Renamed to ...
(adobe_glyph_values): This.
(dump_mac_indices, dump_glyph_list, dump_unicode_values, main):
Updated.
* src/psnames/pstables.h: Regenerated.
* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
Fix return value.
Use `sid_standard_table' and `ps_names_to_unicode' instead of
`t1_standard_glyphs' and `names_to_unicode'.
(PS_Macintosh_Name): Use `ps_glyph_names' instead of
`standard_glyph_names'.
(PS_Standard_Strings): Use `sid_standard_names' instead of
`t1_standard_glyphs'.
* doc/BUGS, doc/TODO: New documents.
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
setjmp() and longjmp() are now used for rollback (i.e. when memory
pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.

* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems).  <limits.h> is included to properly
get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.
(gray_record_cell): Use longjmp().
(gray_set_cell): Use gray_record_cell() for error handling.
(gray_render_line, gray_render_conic, gray_render_cubic): Simplify.
(gray_convert_glyph_inner): New function, using setjmp().
(gray_convert_glyph): Use it.


Provide a public API to manage multiple size objects for a given
FT_Face in the new header file `ftsizes.h'.

* include/freetype/ftsizes.h: New header file,
* include/freetype/internal/ftobjs.h: Use it.
Remove declarations of FT_New_Size and FT_Done_Size (moved to
ftsizes.h).
* include/freetype/config/ftheader.h (FT_SIZES_H): New macro.
* src/base/ftobjs.c (FT_Activate_Size): New function.
* src/cache/ftcmanag.c: Include ftsizes.h.
(ftc_manager_init_size, ftc_manager_flush_size): Use
FT_Activate_Size.

David Turner 78b6740ff2 * include/freetype/ftsizes.h, src/base/ftobjs.c, src/cache/ftcmanag.c:
added a new header, named "ftsizes.h" (FT_SIZES_H) to provide a public
	API to manage multiple size objects for a given FT_Face.

David Turner 686901a1a5 modified the TrueType interpreter to let it
use the new trigonometric functions provided in "fttrigon.h". This
        gets rid of some old 64-bit computation routines, as well as many

        integer type.

src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the
error names for the module it belongs to.

Fixed the bezier stack depths.
* src/base/ftcalc.c (FT_MulFix): Minor rounding fix.
