Un-omitted syntax like RVCT, - `orr %0, %0, %2, lsl #16' is better. Reported by - Johnson Y. Yan. The bug report by Qt developers is - considered too. - - http://bugreports.qt.nokia.com/browse/QTBUG-6521 - -2011-01-15 Werner Lemberg - - [raster] Make bbox handling the same as with Microsoft's rasterizer. - - Right before B/W rasterizing, the bbox gets simply rounded to - integers.

It seems that the increase of the precision in the change - from 2009-06-11 makes a larger jitter value unnecessary. - - * src/raster/ftraster.c (Set_High_Precision): Implement it. - -2011-01-13 Werner Lemberg - - [raster] Handle drop-outs at glyph borders according to Microsoft. - - If a drop-out rule would switch on a pixel outside of the glyph's - bounding box, use the right (or top) pixel instead. This is an - undocumented feature, but some fonts like `Helvetica Neue LT Com 65 - Medium' heavily rely on it. - - Thanks to Greg Hitchcock who explained this behaviour. - - * src/raster/ftraster.c (Vertical_Sweep_Drop, - Horizontal_Sweep_Drop): Implement it. - -2011-01-09 suzuki toshiya - - [cache] Fix Savannah bug #31923, patch drafted by Harsha. - - When a node comparator changes the cached nodes during the - search of a node matching with queried properties, the - pointers obtained before the function should be updated to - prevent the dereference to freed or reallocated nodes. - To minimize the rescan of the linked list, the update is - executed when the comparator notifies the change of cached - nodes. This change depends previous change: - 38b272ffbbdaae276d636aec4ef84af407d16181 - - * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the - top node if the cached nodes are changed. - * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto. - -2011-01-09 suzuki toshiya - - [cache] Notice if a cache query induced the node list change. - - Some node comparators (comparing the cache node contents and the - properties specified by the query) can flush the cache node to - prevent the cache inflation. The change may invalidate the pointers - to the node obtained before the node comparison, so it should be - noticed to the caller. The problem caused by the cache node - changing is reported by Harsha, see Savannah bug #31923. - - * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument - `FT_Bool* list_changed' to indicate the change of the cached nodes - to the caller. - (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by - `_list_changed'. - (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed' - and update it when `FTC_Manager_FlushN' flushes any nodes. - - * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new - FTC_Node_CompareFunc type. - (ftc_gnode_compare): Ditto. - - * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use - TRUE/FALSE macros. - (ftc_basic_gnode_compare_faceid): New argument `FT_Bool* - list_changed' to indicate the change of the cache nodes (anyway, it - is always FALSE). - - * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use - TRUE/FALSE macros. - (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to - indicate the change of the cache nodes (anyway, it is always FALSE). - (ftc_cmap_node_remove_faceid): Ditto. - - * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to - `FTC_CACHE_TRYLOOP_END', because the result is not needed. - (FTC_Cache_Lookup): Watch the change of the cache nodes by - `list_changed'. - (FTC_Cache_RemoveFaceID): Ditto. - - * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use - TRUE/FALSE macros. - (ftc_gnode_compare): New argument `FT_Bool* list_changed' to - indicate the change of the cache nodes (anyway, it is always FALSE). - (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be - passed to `ftc_gnode_compare'. - * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. - - * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool* - list_changed' to indicate the change of the cache nodes, anyway. It - is updated by `FTC_CACHE_TRYLOOP'. - (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be - passed to `ftc_snode_compare'. - * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. - -2011-01-09 suzuki toshiya - - [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'. - - * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd - argument `FTC_Cache cache' to fit FTC_Node_CompareFunc - prototype. - * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway, - `cache' is not used by its child `ftc_gnode_compare'. - -2011-01-09 suzuki toshiya - - [cache] Deduplicate the code to get the top node by a hash. - - There are several duplicated code fragments getting the top node - from a cache by a given hash, like: - - idx = hash & cache->mask; - if ( idx < cache->p ) - idx = hash & ( cache->mask * 2 + 1 ); - pnode = cache->buckets + idx; - - To remove duplication, a cpp-macro to do same work - `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined - configuration, non-`ftc_get_top_node_for_hash' is also introduced. - - * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare - and implement inlined version. - (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'. - * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined - version. - (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'. - (ftc_node_hash_link): Ditto. - (FTC_Cache_Lookup): Ditto. - -2011-01-09 suzuki toshiya - - [cache] inline-specific functions are conditionalized. - - * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for - inlined configuration. This function is a thin wrapper of - `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see - `nodecmp' argument). Under non-inlined configuration, - `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via - `FTC_Cache->clazz.node_compare'. - - * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. - * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for - `ftc_snode_compare'. - * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. - -2011-01-09 suzuki toshiya - - [cache] Correct a type mismatch under non-inlined config. - - * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup' - takes the node via a pointer `FTC_Node*', differently from cpp-macro - `FTC_CACHE_LOOKUP_CMP'. - -2011-01-06 suzuki toshiya - - Update Jamfile to include Bzip2 support. - - * Jamfile: Include src/bzip2 to project. - Comments for lzw, gzip, bzip2 are changed to clarify that - they are for compressed PCF fonts, not others. - (e.g. compressed BDF fonts are not supported yet) - -2011-01-05 suzuki toshiya - - Update Symbian project files to include Bzip2 support. - - Currently, it provides `FT_Stream_OpenBzip2' that returns - unimplemented error always, to prevent unresolved symbol - error for the applications designed for Unix systems. - - * builds/symbian/bld.inf: Include ftbzip2.h. - * builds/symbian/freetype.mmp: Include ftbzip2.c. - -2011-01-05 suzuki toshiya - - Update classic MacOS makefiles to include Bzip2 support. - - Currently, it provides `FT_Stream_OpenBzip2' that returns - unimplemented error always, to prevent unresolved symbol - error for the applications designed for Unix systems. - - * builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o. - * builds/mac/FreeType.m68k_far.make.txt: Ditto. - * builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x. - * builds/mac/FreeType.ppc_classic.make.txt: Ditto. - -2011-01-05 suzuki toshiya - - Update Amiga makefiles to include Bzip2 support. - - Currently, it provides `FT_Stream_OpenBzip2' that returns - unimplemented error always, to prevent unresolved symbol - error for the applications designed for Unix systems. - - * builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c. - * builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c. - * builds/amiga/smakefile: Ditto. - -2011-01-05 suzuki toshiya - - Update pkg-config tools to reflect Bzip2 support. - - * builds/unix/freetype-config.in: Include `-lbz2' to - --libs output, if built with Bzip2 support. - * builds/unix/freetype2.in: Ditto. - -2011-01-05 suzuki toshiya - - * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro. - - SYSTEM_ZLIB is used to switch the builtin zlib source - or system zlib source out of FreeType2. But ftbzip2 - module has no builtin bzip2 library and always requires - system bzip2 library. Thus SYSTEM_BZ2LIB is always yes, - it is not used. - -2011-01-03 Werner Lemberg - - */rules.mk: Handle `*pic.c' files. - -2010-12-31 Werner Lemberg - - * src/cff/cfftypes.h (CFF_MAX_CID_FONTS): Increase to 64. - Problem reported by Tom Bishop . - -2010-12-31 Werner Lemberg - - Improve bzip2 support. - - * include/freetype/ftmoderr.h: Add bzip2. - - * docs/INSTALL.ANY, docs/CHANGES: Updated. - - * src/pcf/README: Updated. - * include/freetype/internal/pcftypes.h: Obsolete, removed. - -2010-12-31 Joel Klinghed - - Add bzip2 compression support to handle *.pcf.bz2 files. - - * builds/unix/configure.raw: Test for libbz2 library. - - * devel/ftoption.h, include/freetype/config/ftoption.h - (FT_CONFIG_OPTION_USE_BZIP2): Define. - * include/freetype/config/ftheader.h (FT_BZIP2_H): Define. - - * include/freetype/ftbzip2.h: New file. - - * src/bzip2/*: New files. - - * src/pcf/pcf.h: s/gzip_/comp_/. - * src/pcf/pcfdrvr.c: Include FT_BZIP2_H. - s/gzip_/comp_/. - (PCF_Face_Init): Handle bzip2 compressed files. - - * docs/formats.txt, modules.cfg: Updated. - -2010-12-25 Harsha - - Apply Savannah patch #7422. - - If we encounter a space in a string then the sbit buffer is NULL, - height and width are 0s. So the check in ftc_snode_compare will - always pass for spaces (comparision with 255). Here the comments - above the condition are proper but the implementation is not.

FWIW, these files may be produced by an application - called `Intaglio' on the Mac, when converting TrueType fonts to - Type 1. - - The fix allows the new invalid behaviour, the old invalid behaviour - and real proper usage of the operator to work the same way as Adobe - interpreters apparently do. - - (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top - two elements of the stack to establish unconditionally the current x - and y coordinates. - - Make the `flex' subroutine handling (OtherSubr 0) put the current - x,y coordinates onto the stack, instead of two dummy uninitialised - values. - -2010-04-14 Ken Sharp - - Fix Savannah bug #29444. - - * src/psaux/psobjs.c (t1_builder_start_point): Accept (invalid) - `lineto' immediately after `hsbw', in accordance with Acrobat, GS, - and others. - -2010-04-14 Michał Cichoń - - Fix Savannah bug #27999. - - * src/cache/ftcmanag.c (FTC_Manager_RemoveFaceID): Only remove - selected entry, not all. - -2010-04-06 Jonathan Kew - - Add overflow check to `fvar' table. - - * src/truetype/ttgxvar.c (TT_Get_MM_Var): Check axis and instance - count. - -2010-04-05 Ken Sharp - - Fix Savannah bug #29335. - - * src/raster/ftraster.c (Line_Up): Use slow multiplication to - prevent overflow.
