5 * src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu, |
|
6 Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are |

11 Always ignore global advance. |
|
12 |
|
13 This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, |
|
14 deprecated, and ignored. The new behavior is what every major user |
|
15 of FreeType has been requesting. Global advance is broken in many |
|
16 CJK fonts. Just ignoring it by default makes most sense. |

27 [autofit] Blur CJK stems if too many to preserve their gaps. |
|
28 |
|
29 When there are too many stems to preserve their gaps in the |
|
30 rasterization of CJK Ideographs at a low resolution, blur the |
|
31 stems instead of showing clumped stems. See |
|
32 http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html |
|

|
34 for details. |
|
35 |
|
36 * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of |
|
37 the previous stem by `has_last_stem' and `last_stem_pos', and skip |
|
38 a stem if the current and previous stem are too near to preserve |
|
39 the gap. |

|
44 |

46 (FT_DEBUG_AUTOFIT): New macro. |
|
47 |

|
49 autofitter. |
|

|
76 Fix reading of signed integers from files on 64bit platforms. |
|
77 |
|
78 Previously, signed integers were converted to unsigned integers, but |
|
79 this can fail because of sign extension. For example, 0xa344a1eb |
|
80 becomes 0xffffffffa344a1eb. |
|
81 |
|
82 We now do the reverse which is always correct because the integer |
|
83 size is the same during the cast from unsigned to signed. |
|
84 |
|
85 * include/freetype/internal/ftstream.h, src/base/ftstream.c |
|
86 (FT_Stream_Get*): Replace with... |
|
87 (FT_Stream_GetU*): Functions which read unsigned integers. |
|
88 Update all macros accordingly. |
|
89 |
|
90 * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated. |
|

274 Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>. |
|
275 |

285 `FT_LOAD_PEDANTIC'. |
|
286 * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, |
|
287 tt_size_init_bytecode, tt_size_ready_bytecode): New argument to |

300 [truetype] Improve handling of invalid references. |
|
301 |
|
302 * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference |
|
303 error codes only if pedantic hinting is active. At the same time, |
|
304 try to provide sane values which hopefully allow useful |
|
305 continuation. Exception to this is CALL and LOOPCALL – due to |
|
306 possible stack corruption it is necessary to bail out. |
|
307 |
|
308 2011-01-31 Werner Lemberg <wl@gnu.org> |

310 [truetype] Improve handling of stack underflow. |
|
311 |
|
312 * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP, |

333 * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with |
|
334 `>' since the description in the specification is incorrect. |

342 * include/freetype/config/ftconfig.h (FT_MulFix_arm): |
|
343 Copy the maintained code from builds/unix/ftconfig.in. |
|
344 Old GNU binutils could not accept the reduced syntax |
|
345 `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT, |
|
346 `orr %0, %0, %2, lsl #16' is better. Reported by |
|
347 Johnson Y. Yan. The bug report by Qt developers is |
|
348 considered too. |

354 [raster] Make bbox handling the same as with Microsoft's rasterizer. |
|
355 |
|
356 Right before B/W rasterizing, the bbox gets simply rounded to |
|
357 integers. This fixes, for example, glyph `three' in font `Helvetica |
|
358 Neue LT Com 65 Medium' at 11ppem. |
|
359 |
|
360 Thanks to Greg Hitchcock who explained this behaviour. |

|
365 |
|
366 Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS. |
|
367 |
|
368 * builds/unix/configure.raw: Consider recent gcc-standard |
|
369 flags to specify architecture in CFLAGS & LDFLAGS |
|
370 harmonization. Requested by Savannah bug #32114, to |
|
371 support multilib feature of BuildRoot SDK correctly. |

373 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
374 |
|
375 Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer. |
|
376 |
|
377 * builds/unix/configure.raw: Some important options that |
|
378 included in CFLAGS but not in LDFLAGS are copied to |
|
379 LDFLAGS, but the last option in CFLAGS was not checked. |
|

386 Horizontal_Sweep_Drop): Implement it. |

387 |
|
388 2011-01-13 Werner Lemberg <wl@gnu.org> |
|
389 |
|
390 [raster] Reduce jitter value. |
|
391 |
|
392 This catches a rendering problem with glyph `x' from Tahoma at |
|
393 10ppem. It seems that the increase of the precision in the change |
|
394 from 2009-06-11 makes a larger jitter value unnecessary. |
|
395 |
|
396 * src/raster/ftraster.c (Set_High_Precision): Implement it. |
|
397 |
|
398 2011-01-13 Werner Lemberg <wl@gnu.org> |
|
399 |
|
400 [raster] Handle drop-outs at glyph borders according to Microsoft. |
|
401 |
|
402 If a drop-out rule would switch on a pixel outside of the glyph's |
|
403 bounding box, use the right (or top) pixel instead. This is an |
|
404 undocumented feature, but some fonts like `Helvetica Neue LT Com 65 |
|
405 Medium' heavily rely on it. |
|
406 |
|
407 Thanks to Greg Hitchcock who explained this behaviour. |
|
408 |
|
409 * src/raster/ftraster.c (Vertical_Sweep_Drop, |

414 [cache] Fix Savannah bug #31923, patch drafted by Harsha. |
|
415 |
|
416 When a node comparator changes the cached nodes during the |
|
417 search of a node matching with queried properties, the |
|
418 pointers obtained before the function should be updated to |
|
419 prevent the dereference to freed or reallocated nodes. |
|
420 To minimize the rescan of the linked list, the update is |
|
421 executed when the comparator notifies the change of cached |
|
422 nodes. This change depends previous change: |
|
423 38b272ffbbdaae276d636aec4ef84af407d16181 |
|
424 |
|
425 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the |
|
426 top node if the cached nodes are changed. |
|
427 * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto. |
|
428 |
|

|
430 |
|
431 [cache] Notice if a cache query induced the node list change. |
|
432 |
|
433 Some node comparators (comparing the cache node contents and the |
|
434 properties specified by the query) can flush the cache node to |
|
435 prevent the cache inflation. The change may invalidate the pointers |
|
436 to the node obtained before the node comparison, so it should be |
|
437 noticed to the caller. The problem caused by the cache node |
|
438 changing is reported by Harsha, see Savannah bug #31923. |
|
439 |
|
440 * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument |
|
441 `FT_Bool* list_changed' to indicate the change of the cached nodes |
|
442 to the caller. |
|
443 (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by |
|
444 `_list_changed'. |
|
445 (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed' |
|
446 and update it when `FTC_Manager_FlushN' flushes any nodes. |
|
447 |
|
448 * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new |
|
449 FTC_Node_CompareFunc type. |
|
450 (ftc_gnode_compare): Ditto. |
|
451 |
|
452 * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use |
|
453 TRUE/FALSE macros. |
|
454 (ftc_basic_gnode_compare_faceid): New argument `FT_Bool* |
|
455 list_changed' to indicate the change of the cache nodes (anyway, it |
|
456 is always FALSE). |
|
457 |
|
458 * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use |
|
459 TRUE/FALSE macros. |
|
460 (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to |
|
461 indicate the change of the cache nodes (anyway, it is always FALSE). |
|
462 (ftc_cmap_node_remove_faceid): Ditto. |
|
463 |
|
464 * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to |
|
465 `FTC_CACHE_TRYLOOP_END', because the result is not needed. |
|
466 (FTC_Cache_Lookup): Watch the change of the cache nodes by |
|
467 `list_changed'. |
|
468 (FTC_Cache_RemoveFaceID): Ditto. |
|
469 |
|
470 * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use |
|
471 TRUE/FALSE macros. |
|
472 (ftc_gnode_compare): New argument `FT_Bool* list_changed' to |
|
473 indicate the change of the cache nodes (anyway, it is always FALSE). |
|
474 (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be |
|
475 passed to `ftc_gnode_compare'. |
|
476 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. |
|
477 |
|
478 * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool* |
|
479 list_changed' to indicate the change of the cache nodes, anyway. It |
|
480 is updated by `FTC_CACHE_TRYLOOP'. |
|
481 (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be |
|
482 passed to `ftc_snode_compare'. |
|
483 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. |
|

|
485 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
486 |
|
487 [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'. |
|
488 |
|
489 * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd |
|
490 argument `FTC_Cache cache' to fit FTC_Node_CompareFunc |
|
491 prototype. |
|
492 * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway, |
|
493 `cache' is not used by its child `ftc_gnode_compare'. |
|
494 |
|
495 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
496 |
|
497 [cache] Deduplicate the code to get the top node by a hash. |
|
498 |
|
499 There are several duplicated code fragments getting the top node |
|
500 from a cache by a given hash, like: |
|
501 |
|
502 idx = hash & cache->mask; |
|
503 if ( idx < cache->p ) |
|
504 idx = hash & ( cache->mask * 2 + 1 ); |
|
505 pnode = cache->buckets + idx; |
|
506 |
|
507 To remove duplication, a cpp-macro to do same work |
|
508 `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined |
|
509 configuration, non-`ftc_get_top_node_for_hash' is also introduced. |
|
510 |
|
511 * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare |
|
512 and implement inlined version. |
|
513 (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'. |
|
514 * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined |
|
515 version. |
|
516 (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'. |
|
517 (ftc_node_hash_link): Ditto. |
|
518 (FTC_Cache_Lookup): Ditto. |
|
519 |
|
520 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
521 |
|
522 [cache] inline-specific functions are conditionalized. |
|
523 |
|
524 * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for |
|
525 inlined configuration. This function is a thin wrapper of |
|
526 `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see |
|
527 `nodecmp' argument). Under non-inlined configuration, |
|
528 `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via |
|
529 `FTC_Cache->clazz.node_compare'. |
|
530 |
|
531 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto. |
|
532 * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for |
|
533 `ftc_snode_compare'. |
|
534 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto. |
|
535 |
|
536 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
537 |
|
538 [cache] Correct a type mismatch under non-inlined config. |
|
539 |
|
540 * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup' |
|
541 takes the node via a pointer `FTC_Node*', differently from cpp-macro |
|
542 `FTC_CACHE_LOOKUP_CMP'. |
|
543 |

546 Update Jamfile to include Bzip2 support. |
|
547 |
|
548 * Jamfile: Include src/bzip2 to project. |
|
549 Comments for lzw, gzip, bzip2 are changed to clarify that |
|
550 they are for compressed PCF fonts, not others. |
|
551 (e.g. compressed BDF fonts are not supported yet) |

|
554 |
|
555 Update Symbian project files to include Bzip2 support. |
|
556 |
|
557 Currently, it provides `FT_Stream_OpenBzip2' that returns |
|
558 unimplemented error always, to prevent unresolved symbol |
|
559 error for the applications designed for Unix systems. |
|
560 |

|
578 |
|
579 Update Amiga makefiles to include Bzip2 support. |
|
580 |
|
581 Currently, it provides `FT_Stream_OpenBzip2' that returns |
|
582 unimplemented error always, to prevent unresolved symbol |
|
583 error for the applications designed for Unix systems. |
|
584 |
|
585 * builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c. |

|
597 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
598 |
|
599 * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro. |
|
600 |
|
601 SYSTEM_ZLIB is used to switch the builtin zlib source |
|
602 or system zlib source out of FreeType2. But ftbzip2 |
|
603 module has no builtin bzip2 library and always requires |
|
604 system bzip2 library. Thus SYSTEM_BZ2LIB is always yes, |
|
605 it is not used. |

|
650 Apply Savannah patch #7422. |
|
651 |
|
652 If we encounter a space in a string then the sbit buffer is NULL, |
|
653 height and width are 0s. So the check in ftc_snode_compare will |
|
654 always pass for spaces (comparision with 255). Here the comments |
|
655 above the condition are proper but the implementation is not. When |
|
656 we create an snode I think it is the proper way to initialize the |
|
657 width to 255 and then put a check for being equal to 255 in snode |
|
658 compare function. |
|
659 |
|
660 * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with |
|
661 value 255. |
|
662 (ftc_snode_compare): Fix condition. |
|

|
670 |
|
671 2010-12-09 Werner Lemberg <wl@gnu.org> |
|
672 |
|
673 [cff] Allow `hlineto' and `vlineto' without arguments. |
|
674 |
|
675 We simply ignore such instructions. This is invalid, but it doesn't |
|
676 harm; and indeed, there exist such subsetted fonts in PDFs. |
|
677 |
|
678 Reported by Albert Astals Cid <aacid@kde.org>. |

679 |
|
680 * src/cff/cffgload.c (cff_decoder_parse_charstrings) |

800 [ftsmooth] Improve rendering. |
|
801 |
|
802 * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3, |
|
803 cubic deviations have been estimated _after_ UPSCALE, whereas |
|
804 conic ones have been evaluated _before_ UPSCALE, which produces |
|
805 inferior rendering results. Fix this. |
|
806 Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has |
|
807 been tested with demo images sent to the mailing list. See |

|
837 |
|
838 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert |
|
839 the type of `_idx' from FT_PtrDist (by previous change) |
|
840 to original FT_UFast, to match with FT_CacheRec. |

|
843 |
|
844 [cache] Change the hash types to FT_PtrDist. |
|
845 |
|
846 On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) |
|
847 variables are inappropriate to calculate hash values |
|
848 from the memory address (64-bit). The hash variables |
|
849 are extended from FT_ULong to FT_PtrDist and new |
|
850 hashing macro functions are introduced. The hash |
|
851 values on 16-bit memory platforms are changed, but |
|
852 ILP32 and LP64 are not changed. The hash value in |
|
853 the cache subsystem is not reverted to the memory |
|
854 address, so using signed type FT_PtrDist is safe. |
|
855 |
|
856 * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash |
|
857 function to replace `FTC_FACE_ID_HASH' for portability. |
|
858 * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace |
|
859 `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'. |
|
860 * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. |
|
861 |
|
862 * src/cache/ftccache.h (FTC_NodeRec): The type of the |
|
863 member `hash' is changed from FT_UInt32 to FT_PtrDist. |
|
864 |
|
865 * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the |
|
866 argument `hash' is changed from FT_UInt32 to FT_PtrDist. |
|
867 (FTC_Cache_NewNode): Ditto. |
|
868 * src/cache/ftccache.c (ftc_cache_add): Ditto. |
|
869 (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto. |
|
870 * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto. |
|
871 * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto. |
|
872 |
|
873 * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type |
|
874 of the internal variable `hash' is changed to FT_PtrDist |
|
875 from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto. |
|
876 (FTC_SBitCache_Lookup): Ditto. |
|
877 (FTC_SBitCache_LookupScaler): Ditto. |
|
878 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto. |
|
879 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto. |
|
880 Also the type of the internal variable `_idx' is changed to |
|
881 FT_PtrDist from FT_UFast for better pointer calculation. |
|

884 |
|
885 [cache] Hide internal macros incompatible with LLP64. |
|
886 |
|
887 `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and |
|
888 `FTC_IMAGE_TYPE_HASH' are enclosed by |
|
889 FT_CONFIG_OPTION_OLD_INTERNALS and hidden from |
|
890 normal clients. |
|
891 |
|
892 For the history of these macros, see the investigation: |

|
895 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
896 |
|
897 Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist. |
|
898 |
|
899 On LLP64 platforms (e.g. Win64), unsigned long (32-bit) |
|
900 cannot cover the memory address (64-bit). `FT_MEM_VAL' is |
|
901 used for hashing only and not dereferred, so using signed |
|
902 type FT_PtrDist is safe. |
|
903 |
|
904 * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the |
|
905 return value from FT_ULong to FT_PtrDist. |
|
906 (ft_mem_table_resize): The type of hash is changed to |
|
907 FT_PtrDist. (ft_mem_table_get_nodep): Ditto. |
|
908 |
|
909 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
910 |
|
911 Replace "%lx" for memory address by "%p", LLP64 platforms. |
|
912 |
|
913 On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover |
|
914 the memory address (64-bit). Also the casts from the pointer |
|
915 type to long int should be removed to preserve the address |
|
916 correctly. |
|
917 |
|
918 * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". |
|
919 (End_Profile) Ditto. |
|
920 * src/truetype/ttinterp.c (Init_Context): Ditto. |
|

926 FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL. |
|
927 |
|
928 * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and |
|
929 replace it everywhere with ONE_PIXEL/8. |

933 [raccess] Skip unrequired resource access rules by Darwin VFS. |
|
934 |
|
935 When a resource fork access rule by Darwin VFS could open the |
|
936 resource fork but no font is found in it, the rest of rules |
|
937 by Darwin VFS are skipped. It reduces the warnings of the |
|
938 deprecated resource fork access method by recent Darwin kernel. |
|
939 Fix MacPorts ticket #18859: |
|
940 http://trac.macports.org/ticket/18859 |
|
941 |
|
942 * src/base/ftobjs.c (load_face_in_embedded_rfork): |
|
943 When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it |
|
944 means that the file is possible to be `fopen'-ed but zero-sized. |
|
945 Also there is a case that the resource fork is not zero-sized, |
|
946 but no supported font exists in it. If a rule by Darwin VFS |
|
947 falls into such cases, there is no need to try other Darwin VFS |
|
948 rules anymore. Such cases are marked by vfs_rfork_has_no_font. |
|
949 If it is TRUE, the Darwin VFS rules are skipped. |

|
953 [raccess] Grouping resource access rules based on Darwin VFS. |
|
954 |
|
955 MacOS X/Darwin kernel supports a few tricky methods to access |
|
956 a resource fork via ANSI C or POSIX interface. Current resource |
|
957 fork accessor tries all possible methods to support all kernels. |
|
958 But if a method could open a resource fork but no font is found, |
|
959 there is no need to try other methods older than tested method. |
|
960 To determine whether the rule index is for Darwin VFS, a local |
|
961 function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced. |
|
962 To use this function in ftobjs.c etc but it should be inlined, |
|
963 it is exposed by ftbase.h. |
|
964 |
|
965 * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify |
|
966 the rules to access the resource fork. |
|
967 (raccess_guess_rec): New structure to bind the rule function and |
|
968 rule enum type. |
|
969 (FT_Raccess_Guess): The list of the rule functions is replaced by |
|
970 (raccess_guess_table): This. This is exposed to be used by other |
|
971 intra module functions. |
|
972 (raccess_rule_by_darwin_vfs): A function to return a boolean |
|
973 if the rule specified by the rule index is based on Darwin VFS. |
|

977 Prevent to open a FT_Stream for zero-sized file on non-Unix. |
|
978 |
|
979 builds/unix/ftsystem.c prevents to open an useless stream from |
|
980 zero-sized file and returns FT_Err_Cannot_Open_Stream, but the |
|
981 stream drivers for ANSI C, Amiga and VMS return useless streams. |
|
982 For cross-platform consistency, all stream drivers should act |
|
983 same. |
|
984 |
|
985 * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened |
|
986 file is zero, FT_Err_Cannot_Open_Stream is returned. |
|
987 * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto. |

1173 [sfnt] Prevent overrunning in `post' table parser. |
|
1174 See Savannah bug #31040. |
|
1175 |
|
1176 * src/sfnt/ttpost.c (load_post_names): Get the length of `post' |
|
1177 table and pass the limit of `post' table to `load_format_20' and |
|
1178 `load_format_25'. |
|
1179 (load_format_20): Stop the parsing when we reached at the limit of |
|
1180 `post' table. If more glyph names are required, they are filled by |
|
1181 NULL names. |

1185 [truetype] Don't duplicate size->twilight structure to be freed. |
|
1186 See Savannah bug #31040 for detail. |
|
1187 |
|
1188 * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate |
|
1189 FT_GlyphZoneRec size->twilight to be freed. If duplicated, |
|
1190 `FT_FREE' erases the duplicated pointers only and leave original |
|
1191 pointers. They can cause the double-free crash when the burst |
|
1192 errors occur in TrueType interpreter and `free_buffer_in_size' is |
|
1193 invoked repeatedly. |

|
1216 Fix minor issues reported by <muktha.narayan@wipro.com>. |
|
1217 |
|
1218 * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove |
|
1219 redundant conditional check. |
|
1220 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto. |
|
1221 * src/cff/cffload.c (cff_encoding_load): Remove conditional check |
|
1222 which always evaluates to `true'. |
|
1223 * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points): |
|
1224 Ditto. |

1225 * src/truetype/ttinterp.c (Ins_IUP): Ditto. |

1232 Ignore the environmental setting of LIBTOOL. |
|
1233 Patch is suggested by Adrian Bunk, to prevent unexpected |
|
1234 reflection of environmental LIBTOOL. See: |
|
1235 http://savannah.nongnu.org/patch/?7290 |
|
1236 |
|
1237 * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to |
|
1238 $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR) |
|
1239 by default. |
|
1240 * configure: When configured for the building out of source tee, |
|
1241 FT_LIBTOOL_DIR is set to $(OBJ_DIR). |

1245 [truetype] Decrease the trace level catching the interpreter error. |
|
1246 |
|
1247 * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level |
|
1248 showing the error when the interpreter returns with an error, |
|
1249 from` FT_TRACE7' to `FT_TRACE1'. |
|

|
1253 [truetype] Prevent bytecode reuse after the interpretation error. |
|
1254 |
|
1255 * src/truetype/ttinterp.c (free_buffer_in_size): New function to |
|
1256 free the buffer allocated during the interpretation of this glyph. |
|
1257 (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if |
|
1258 an error occurs in the bytecode interpretation. The interpretation |
|
1259 of invalid bytecode may break the function definitions and referring |
|
1260 them in later interpretation is danger. By unsetting these flags, |
|
1261 `fpgm' and `prep' tables are executed again in next interpretation. |
|
1262 |
|
1263 This fixes Savannah bug #30798, reported by Robert Święcki. |

|
1275 |
|
1276 * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20: |
|
1277 The threshold for SIDs is not applicable here. I misinterpreted the |
|
1278 `SID values 65000 and above are available for implementation use' |

1285 Force hinting when the font lacks its familyname. |
|
1286 |
|
1287 In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt |
|
1288 stream may lack `name' table because they are not required. Hinting |
|
1289 for nameless fonts is safer for PDFs including embedded Chinese |
|
1290 fonts. Written by David Bevan, see: |

1691 |

1695 Technical Note 5040, type 0 segment is a comment only and should not |
|
1696 be loaded for the interpreter. Reported by Robert Święcki. |

2044 Fix Savannah bug #29846. |
|
2045 |
|
2046 Previously we discovered fonts which used `setcurrentpoint' to set |
|
2047 the initial point of a contour to 0,0. This caused FreeType to |
|
2048 raise an error, because the `setcurrentpoint' operator is only |
|
2049 supposed to be used with the results from an OtherSubr subroutine. |
|
2050 |
|
2051 This was fixed by simply ignoring the error and carrying on. |
|
2052 |
|
2053 Now we have found a font which uses setcurrentpoint to actually |
|
2054 establish a non-zero point for a contour during the course of a |
|
2055 glyph program. FWIW, these files may be produced by an application |
|
2056 called `Intaglio' on the Mac, when converting TrueType fonts to |
|
2057 Type 1. |
|
2058 |
|
2059 The fix allows the new invalid behaviour, the old invalid behaviour |
|
2060 and real proper usage of the operator to work the same way as Adobe |
|
2061 interpreters apparently do. |
|
2062 |
|
2063 (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top |
|
2064 two elements of the stack to establish unconditionally the current x |
|
2065 and y coordinates. |
|
2066 |
|
2067 Make the `flex' subroutine handling (OtherSubr 0) put the current |
|
2068 x,y coordinates onto the stack, instead of two dummy uninitialised |
|
2069 values. |
|
