2005-06-05 Werner Lemberg <wl@gnu.org> * Add copyright notices to all files which don't have one. * docs/license.txt: Renamed to... * docs/LICENSE.TXT: This. * docs/FTL.txt: Renamed to... * docs/FTL.TXT: This. * docs/GPL.txt: Renamed to... * docs/GPL.TXT: This. * docs/PATENTS: Slightly reworded. Suggested by Sylvain Beucler <beuc@gnu.org>. 2005-06-04 Werner Lemberg <wl@gnu.org> * include/freetype/ftimage.h (FT_Outline_MoveToFunc, FT_Outline_LineToFunc, FT_Outline_ConicToFunc, FT_Outline_CubicToFunc, FT_Raster_RenderFunc), include/freetype/ftrender.h (FT_Glyph_TransformFunc, FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Don't use `const' to stay compatible with FreeType 2.1.9. 2005-06-01 Adam D. Moss <adam@gimp.org> * src/base/ftstroke.c (ft_stroker_inside): Revert `sigma' patch from 2004-07-11; this gives much better results under normal circumstances. 2005-05-30 Chia I Wu <b90201047@ntu.edu.tw> * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Minor documentation improvements. * include/freetype/ftoutln.h (FT_Outline_Embolden): Fix typos. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Add support for bitmap of pixel_mode FT_PIXEL_MODE_GRAY2 or FT_PIXEL_MODE_GRAY4. If xstr is larger than 8 and bitmap is of pixel_mode FT_PIXEL_MODE_MONO, set xstr to 8 instead of returning error. 2005-05-29 Chia I Wu <b90201047@ntu.edu.tw> * src/base/ftbitmap.c (FT_Bitmap_Embolden): Fix emboldening bitmap of mode FT_PIXEL_MODE_GRAY. Also add support for mode FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V. (ft_bitmap_assure_buffer): FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V should have ppb (pixel per byte) 1. Zero the padding when there's no need to allocate memory. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle slot->advance too. More suited emboldening strength. 2005-05-28 Chia I Wu <b90201047@ntu.edu.tw> * src/base/ftbitmap.c (FT_Bitmap_Embolden): Handle negative pitch. Handle FT_PIXEL_MODE_GRAY with num_gray != 256. Improve speed for FT_PIXEL_MODE_GRAY. (ft_bitmap_assure_buffer): Accept FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V. 2005-05-27 Chia I Wu <b90201047@ntu.edu.tw> * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Initialize `error'. * src/base/ftobjs.c (ft_cmap_done_internal): New function. (FT_CMap_Done): Remove cmap from cmap list. (destroy_charmaps, FT_CMap_New): Don't call FT_CMap_Done but ft_cmap_done_internal. 2005-05-26 Werner Lemberg <wl@gnu.org> * docs/GPL.txt: Update postal address of FSF. 2005-05-26 Chia I Wu <b90201047@ntu.edu.tw> * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Improve documentation. * src/base/ftsynth.c (FT_BOLD_THRESHOLD): Removed. (FT_GlyphSlot_Embolden): Check whether slot is bitmap owner. Always modify the metrics. 2005-05-24 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2005-05-24 Chia I Wu <b90201047@ntu.edu.tw> * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): New declaration. * include/freetype/ftoutln.h (FT_Outline_Embolden): New declaration. * src/base/ftbitmap.c (ft_bitmap_assure_buffer): New auxiliary function. (FT_Bitmap_Embolden): New function. * src/base/ftoutln.c (FT_Outline_Embolden): New function. * src/base/ftsynth.c: Don't include FT_INTERNAL_CALC_H and FT_TRIGONOMETRY_H but FT_BITMAP_H. (FT_GlyphSlot_Embolden): Use FT_Outline_Embolden or FT_Bitmap_Embolden. 2005-05-24 Werner Lemberg <wl@gnu.org> * configure: Always remove config.mk, builds/unix/unix-def.mk, and builds/unix/unix-cc.mk. This fixes repeated calls of the script. Reported by Nelson Beebe and Behdad Esfahbod. * README.CVS: Mention file permissions. 2005-05-23 Werner Lemberg <wl@gnu.org> * builds/amiga/makefile.os4 (WARNINGS), builds/compiler/gcc-dev.mk (CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove -fno-strict-aliasing. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c -- it is currently loaded from ttsbit.c. 2005-05-23 Behdad Esfahbod <behdad@cs.toronto.edu> Say you have `(Foo*)x' and want to assign, pass, or return it as `(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler would warn you that type casting incompatible pointer types breaks strict-aliasing. The solution is to cast to `(void*)' instead which is the generic pointer type, so the compiler knows that it should make no strict-aliasing assumption on `x'. But the problem with `(void*)x' is that seems like in C++, unlike C, `void*' is not a generic pointer type and assigning `void*' to `Bar*' without a cast causes an error. The solution is to cast to `Bar*' too, with `(Bar*)(void*)x' as the result -- this is what the patch does. * include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP), include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove cast on lvalue, use a temporary pointer instead. Cast temporarily to (void*) to not break strict aliasing. * include/freetype/internal/ftmemory.h (FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE), src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*) to not break strict aliasing. * src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information. * builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing. 2005-05-23 David Turner <dturner@freetype.org> Fix Savannah bug #12213 (incorrect behaviour of the cache sub-system in low-memory conditions). * include/freetype/cache/ftccache.h (FTC_CACHE_TRYLOOP, FTC_CACHE_TRYLOOP_END): New macros. * src/cache/ftccache.c (FTC_Cache_NewNode), src/cache/ftcsbits.c (ftc_snode_compare): Use FT_CACHE_TRYLOOP and FTC_CACE_TRYLOOP_END. 2005-05-23 Werner Lemberg <wl@gnu.org> * src/base/rules.mk (BASE_SRC): Don't add ftsynth.c here but... (BASE_EXT_SRC): Here. 2005-05-22 Werner Lemberg <wl@gnu.org> * src/base/ftrfork.c (raccess_guess_apple_generic): Mark `version_number' and `entry_length' as unused. (raccess_guess_linux_double_from_file_name): Remove `memory'. (raccess_make_file_name): Mark `error' as unused. * src/bdf/bdflib.c (_bdf_parse_properties): Remove `memory'. * src/cid/cidobjs.c (cid_face_init): Remove `psnames'. * src/sfnt/sfobjs.c (sfnt_load_face): Remove `memory'. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas, ft_var_load_avar): Mark `error' as unused. * src/base/rules.mk (BASE_SRC): Add ftsynth.c. 2005-05-21 David Turner <david@freetype.org> * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Fix a bug that produced unpleasant artefacts when trying to embolden very sharp corners. 2005-05-20 Werner Lemberg <wl@gnu.org> * docs/CHANGES: Updated. 2005-05-20 Chia I Wu <b90201047@ntu.edu.tw> * src/base/ftbitmap.c: Don't include FT_FREETYPE_H and FT_IMAGE_H but FT_BITMAP_H.
