2001-10-25 David Turner <david@freetype.org> * include/freetype/config/ftoption.h: updated comment to explain precisely how to use project-specific macro definitions without modifying this file manually.. 2001-10-24 Tom Kacvinsky <tjk@ams.org> * builds/unix/ftsystem.c (FT_New_Memory): Added a missing `}'. 2001-10-23 David Turner <david@freetype.org> * 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.. * src/autohint/ahglyph.c, src/raster/ftraster.c, src/smooth/ftgrays.c: replaced liberal uses of "memset" by the MEM_Set macro instead.. 2001-10-22 David Turner <david@freetype.org> * builds/unix/ftsystem.c, builds/vms/ftsystem.c, builds/amiga/ftsystem.c, src/base/ftdbgmem.c: updated the memory debugger and platform-specific implementations of 'ftsystem' in order to be able to debug memory allocations on Unix, VMS and Amiga too !! * src/pshinter/pshalgo2.c (psh2_hint_table_record_mask): removed some bogus warnings.. * 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 ?? * src/base/ftdbgmem.c: new debugging memory manager. You must define the FT_DEBUG_MEMORY macro in "ftoption.h" to enable it. It will record every memory block allocated and report simple errors like memory leaks and double deletes. * include/freetype/config/ftoption.h: added the FT_DEBUG_MEMORY macro definition * src/base/ftsystem.c (FT_New_Memory, FT_Done_Memory): modified the base component to use the debugging memory manager when the macro FT_DEBUG_MEMORY is defined.. 2001-10-21 Tom Kacvinsky <tjk@ams.org> * src/cff/cffload.c (CFF_Done_Font): Free subfonts array only if we are working with a CID keyed CFF font. Otherwise, a variable that was never allocated memory might freed. This is a correction to the previous patch for freeing subfonts. 2001-10-21 Tom Kacvinsky <tjk@ams.org> * src/cff/cffload.c (CFF_Done_Font): Free the subfonts array to avoid a memory leak. 2001-10-21 David Turner <david@freetype.org> * src/pshinter/pshalgo2.c, src/pshinter/pshalgo1.c, src/pshinter/pshglob.c: removing compiler warnings in pedantic modes (in multi-object compilation mode, mainly) 2001-10-20 Tom Kacvinsky <tjk@ams.org> * src/type1/t1load.c (parse_encoding): Add a test to make sure that custom encodings (i.e., neither StandardEncoding nor ExpertEncoding) are not loaded twice when the Type 1 font is synthetic. * src/type1/t1load.c (parse_font_name, parse_subrs): Added a test for when loading synthetic fonts to make sure that the font name and subrotuines are not loaded twice. This is to remove a memory leak that occured because the original memory blocks for these objects were not deallocated when the objects were parsed the second time. 2001-10-19 David Turner <david@freetype.org> * src/smooth/ftgrays.c, src/pshinter/pshglob.h, src/pshinter/pshrec.c, src/pshinter/pshalgo2.c: getting rid of compiler warnings * src/pshinter/module.mk, src/pshinter/rules.mk: adding control files to build the postscript hinter with the "old" build system 2001-10-19 Jacob Jansen <joukj@hrem.stm.tudelft.nl> * descrip.mms, src/pshinter/descrip.mms: updates to the VMS build files. 2001-10-18 David Turner <david@freetype.org> * src/psnames/pstables.h, src/tools/glnames.py: rewrote the "glnames.py" script used to generate the "pstables.h" header file. The old one contained a bug (yes !!) that made FreeType return incorrect glyph names for certain glyphs.. * src/truetype/ttdriver.c: changing computation of pixel size from character size to use rounding. This is an experiment to see if this gives values similar to Windows for scaled ascent/descent/etc.. * src/base/ftcalc.c (FT_Div64by32): changed the implementation slightly since the original code was mis-compiled on Mac machines using the MPW C compiler.. * src/base/ftobjs.c (FT_Realloc): when a memory block was grown through FT_Realloc, the new bytes were not set to 0, which created some strange bugs in the Postscript hinter * src/cid/cidgload.c: adding support to new postscript hinter * include/freetype/internal/psglobal.h, include/freetype/internal/pshints.h, include/freetype/config/ftmodule.h, src/pshinter/Jamfile, src/pshinter/pshalgo.h, src/pshinter/pshalgo1.h, src/pshinter/pshalgo1.c, src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshglob.h, src/pshinter/pshglob.c, src/pshinter/pshinter.c, src/pshinter/pshmod.c, src/pshinter/pshmod.h, src/pshinter/pshrec.c, src/pshinter/pshrec.h : Adding new postscript hinter module * include/freetype/internal/ftobjs.h, include/freetype/internal/internal.h, include/freetype/internal/psaux.h, include/freetype/internal/t1types.h, src/psaux/psobjs.c, src/psaux/psobjs.h, src/psaux/t1decode.h, src/psaux/t1decode.c, src/type1/t1driver.c, src/type1/t1gload.c, src/type1/t1objs.c, src/type1/t1objs.h : updates to use the new postscript hinter * tests/Jamfile, tests/gview.c: Adding a new glyph hinting viewer/debugger to the source tree. Note that you will _not_ be able to compile it since it depends on an unavailable graphics library named "Nirvana" to render vector images.. 2001-10-17 David Turner <david@freetype.org> * Version 2.0.5 released. ========================= * include/freetype/freetype.h, include/internal/ftobjs.h, src/base/ftobjs.c, src/sfnt/sfdriver.c, type1/t1driver.c, cid/cidriver.c: Adding a new function named 'FT_Get_Postscript_Name' to retrieve the Postscript name of a given font. Should work with all formats except pure CFF/CEF fonts (this will be added soon). * README, docs/CHANGES: updated for 2.0.5 release 2001-10-08 David Turner <david@freetype.org> 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. 2001-10-07 Richard Barber <rich@solutionuk.com> * src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented correct LRU behaviour. 2001-10-07 David Turner <david@freetype.org> 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. 2001-10-07 David Turner <david@freetype.org> 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. 2001-09-20 Detlef W
