Problem reported by Chris Liddel <chris.liddell@artifex.com>.
2011-02-01[cff] Ignore unknown operators in charstrings.Werner Lemberg1-5/+5
Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing message for unknown operators and continue instead of exiting with a syntax error.
2011-02-01[truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also.Werner Lemberg3-20/+35
* src/truetype/ttgload.c (tt_loader_init): Handle `FT_LOAD_PEDANTIC'. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_init_bytecode, tt_size_ready_bytecode): New argument to handle pedantic mode. * src/truetype/ttobjs.h: Updated.
2011-01-31[truetype] Protect jump instructions against endless loops.Werner Lemberg1-21/+27
* src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error if offset is zero.
2011-01-31[truetype] Improve handling of invalid references.Werner Lemberg1-43/+50
* src/truetype/interp.c: Set even more TT_Err_Invalid_Reference error codes only if pedantic hinting is active. At the same time, try to provide sane values which hopefully allow useful continuation. Exception to this is CALL and LOOPCALL – due to possible stack corruption it is necessary to bail out.
2011-01-31[truetype] Improve handling of stack underflow.Werner Lemberg1-13/+36
* src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, Ins_DELTAC): Exit with error only if `pedantic_hinting' is set. Otherwise, try to do something sane.
2011-01-30Whitespace.Werner Lemberg1-2/+3
2011-01-30* src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message.Werner Lemberg2-4/+3
2011-01-30[truetype]: Fix behaviour of MIAP for invalid arguments.LIU Sun-Liang1-1/+2
* src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in case of error.
2011-01-23[autofit] Some formatting and clean-ups.Werner Lemberg5-61/+59
2011-01-18[truetype] Fix handling of MIRP instruction.Werner Lemberg1-1/+15
Thanks to Greg Hitchcock who explained the issue. * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with `>' since the description in the specification is incorrect. This fixes, for example, glyph `two' in font `Helvetica Neue LT Com 65 medium' at 15ppem.
2011-01-15[raster] Make bbox handling the same as with Microsoft's rasterizer.Werner Lemberg1-0/+8
Right before B/W rasterizing, the bbox gets simply rounded to integers. This fixes, for example, glyph `three' in font `Helvetica Neue LT Com 65 Medium' at 11ppem. Thanks to Greg Hitchcock who explained this behaviour. * src/raster/ftrend1.c (ft_raster1_render): Implement it.
2011-01-14[raster] Add undocumented drop-out rule to the other bbox side also.Werner Lemberg1-3/+9
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement it.
2011-01-13[raster] Reduce jitter value.Werner Lemberg1-2/+24
This catches a rendering problem with glyph `x' from Tahoma at 10ppem. 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[raster] Handle drop-outs at glyph borders according to Microsoft.Werner Lemberg1-0/+10
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[cache] Fix Savannah bug #31923, patch drafted by Harsha.suzuki toshiya2-0/+47
When a node comparator changes the cached nodes during the search of a node matching with queried properties, the pointers obtained before the functon 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[cache] Notice if a cache query induced the node list change.suzuki toshiya9-20/+53
Some node comparators (comparing the cache node content 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 the change 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.
