| |
| [ftstroke] Major revision. |
| |
| The main problems |
| ----------------- |
| |
| o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter |
| joins (not bevel joins) were generated. Indeed, the meanings of |
| `miter' and `bevel' were incorrectly reversed (consistently) in |
| both the code and comments. |
| |
| o The way bevel joins were constructed (whether specified |
| explicitly, or created as a result of exceeding the miter limit) |
| did not match what is required for stroked text in PostScript or |
| PDF. |
| |
| The main fixes |
| -------------- |
| |
| o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected. |
| |
| o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been |
| introduced to support PostScript and PDF miter joins. |
| |
| o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an |
| alias for FT_STROKER_LINEJOIN_MITER. |
| |
| Additionally, a variety of stroking errors have been fixed. These |
| would cause various artifacts (including points `at infinity'), |
| especially when stroking poor quality fonts. |
| |
| See |
| |
| http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html |
| |
| for example documents. The FreeType stroker now produces results |
| very similar to that produced by GhostScript and Distiller for these |
| fonts. |
| |
| Other problems |
| -------------- |
| |
| The following problems have been resolved: |
| |
| o Inside corners could be generated incorrectly. Intersecting the |
| inside corner could cause a missing triangular area and other |
| effects. |
| |
| The intersection point can only be used if the join is between |
| two lines and both lines are long enough. The `optimization' |
| condition in `ft_stroker_inside' has been corrected; this |
| requires the line length to be passed into various functions and |
| stored in `FT_StrokerRec'. |
| |
| o Incorrect cubic curves could be generated. The angle |
| calculations in `FT_Stroker_CubicTo' have been corrected to |
| handle the case of the curve crossing the +/-PI direction. |
| |
| o If the border radius was greater than the radius of curvature of |
| a curve, then the negative sector would end up outside (not |
| inside) the border. This situation is now recognized and the |
| negative sector is circumnavigated in the opposite direction. |
| (If round line joins are being used, this code is disabled |
| because the line join will always cover the negative sector.) |
| |
| o When a curve is split, the arcs may not join smoothly (especially |
| if the curve turns sharply back on itself). Changes in |
| direction between adjacent arcs were not handled. A round |
| corner is now added if the deviation from one arc to the next is |
| greater than a suitable threshold. |
| |
| o The current direction wasn't retained if a the outline contained |
| a zero length lineto or a curve that was determined to be |
| `basically a point'. This could cause a spurious join to be |
| added. |
| |
| o Cubics with close control points could be mishandled. All eight |
| cases are now distinguished correctly. |
| |
| Other improvements |
| ------------------ |
| |
| o Borders for cubic curves could be too `flat'. |
| FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent |
| this. |
| |
| o The handling and use of movable points has been simplified a |
| little. |
| |
| o Various values are now computed only if the results are actually |
| needed. |
| |
| o The directions of the outer and inner borders have been swapped, |
| as recommended by Graham Asher. |

| [autofit] Add bluezones for CJK Ideographs. |
| |
| To remove extremas of vertical strokes of CJK Ideographs at |
| low resolution and make the top and bottom horizontal stems |
| aligned, bluezones for CJK Ideographs are calculated from |
| sample glyphs. At present, vertical bluezones (bluezones |
| to align vertical stems) are disabled by default. For detail, see |

| |
| [truetype] Always check the checksum to identify tricky fonts. |
| |
| Because some PDF generators mangle the family name badly, |
| the trickyness check by the checksum should be invoked always. |

| added. |
| |
| 2011-04-21 Behdad Esfahbod <behdad@behdad.org> |

| Always ignore global advance. |
| |
| This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant, |

| [autofit] Blur CJK stems if too many to preserve their gaps. |
| |
| When there are too many stems to preserve their gaps in the |
| rasterization of CJK Ideographs at a low resolution, blur the |
| stems instead of showing clumped stems. See |
| http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html |
| http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html |
| for details. |
| |
| * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of |
| the previous stem by `has_last_stem' and `last_stem_pos', and skip |
| a stem if the current and previous stem are too near to preserve |
| the gap. |

| |
| Fix reading of signed integers from files on 64bit platforms. |
| |
| Previously, signed integers were converted to unsigned integers, but |
| this can fail because of sign extension. For example, 0xa344a1eb |
| becomes 0xffffffffa344a1eb. |
| |
| We now do the reverse which is always correct because the integer |
| size is the same during the cast from unsigned to signed. |
| |
| * include/freetype/internal/ftstream.h, src/base/ftstream.c |
| (FT_Stream_Get*): Replace with... |
| (FT_Stream_GetU*): Functions which read unsigned integers. |
| Update all macros accordingly. |

| |
| [truetype] Improve handling of invalid references. |
| |
| * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference |

| [raster] Add undocumented drop-out rule to the other bbox side also. |

| |
| [raster] Reduce jitter value. |
| |
| 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 Werner Lemberg <wl@gnu.org> |
| |
| [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. |

| [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 <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [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 <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [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 <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [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 <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [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 <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [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'. |
| |

| |
| Update Jamfile to include Bzip2 support. |
| |
| * Jamfile: Include src/bzip2 to project. |

| (e.g. compressed BDF fonts are not supported yet) |
| |
| 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Update Symbian project files to include Bzip2 support. |
| |

| |
| * builds/symbian/bld.inf: Include ftbzip2.h. |

| |
| Update pkg-config tools to reflect Bzip2 support. |
| |
| * builds/unix/freetype-config.in: Include `-lbz2' to |

| * builds/unix/freetype2.in: Ditto. |
| |
| 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| * 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. |

| 2010-12-25 Harsha <mm.harsha@gmail.com> |
| |
| 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. When |
| we create an snode I think it is the proper way to initialize the |
| width to 255 and then put a check for being equal to 255 in snode |
| compare function. |
| |
| * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with |
| value 255. |
| (ftc_snode_compare): Fix condition. |
| |
| 2010-12-13 Werner Lemberg <wl@gnu.org> |

| * src/base/ftobjs.c (FT_Set_Renderer): Increment `parameters'. |
| |
| 2010-12-09 Werner Lemberg <wl@gnu.org> |
| |
| [cff] Allow `hlineto' and `vlineto' without arguments. |
| |
| We simply ignore such instructions. This is invalid, but it doesn't |
| harm; and indeed, there exist such subsetted fonts in PDFs. |
| |
| Reported by Albert Astals Cid <aacid@kde.org>. |
| |
| * src/cff/cffgload.c (cff_decoder_parse_charstrings) |
| [cff_op_hlineto]: Ignore instruction if there aren't any arguments |
| on the stack. |

| Fix Savannah bug #31645. |
| |
| * src/truetype/ttobjs.c (tt_check_trickyness): Divided to... |

| |
| Since 2010-07-04, `find_variant_selector_charmap' returns |
| the first cmap subtable always under rogue-compatible |

| |
| 2010-11-01 Alexei Podtelezhnikov <apodtele@gmail.com> |
| |
| [ftsmooth] Improve rendering. |
| |
| * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3, |
| cubic deviations have been estimated _after_ UPSCALE, whereas |
| conic ones have been evaluated _before_ UPSCALE, which produces |
| inferior rendering results. Fix this. |

| |
| * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv |
| since the involved multiplication exceeds 32 bits. |
| |
| 2010-10-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'. |

| to original FT_UFast, to match with FT_CacheRec. |
| |
| 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] Change the hash types to FT_PtrDist. |
| |
| On LLP64 platforms (e.g. Win64), FT_ULong (32-bit) |
| variables are inappropriate to calculate hash values |
| from the memory address (64-bit). The hash variables |
| are extended from FT_ULong to FT_PtrDist and new |
| hashing macro functions are introduced. The hash |
| values on 16-bit memory platforms are changed, but |
| ILP32 and LP64 are not changed. The hash value in |
| the cache subsystem is not reverted to the memory |
| address, so using signed type FT_PtrDist is safe. |
| |
| * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash |
| function to replace `FTC_FACE_ID_HASH' for portability. |
| * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace |
| `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'. |
| * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. |
| |
| * src/cache/ftccache.h (FTC_NodeRec): The type of the |
| member `hash' is changed from FT_UInt32 to FT_PtrDist. |
| |
| * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the |
| argument `hash' is changed from FT_UInt32 to FT_PtrDist. |
| (FTC_Cache_NewNode): Ditto. |
| * src/cache/ftccache.c (ftc_cache_add): Ditto. |
| (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto. |
| * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto. |
| * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto. |
| |
| * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type |
| of the internal variable `hash' is changed to FT_PtrDist |
| from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto. |
| (FTC_SBitCache_Lookup): Ditto. |
| (FTC_SBitCache_LookupScaler): Ditto. |
| * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto. |
| * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto. |
| Also the type of the internal variable `_idx' is changed to |
| FT_PtrDist from FT_UFast for better pointer calculation. |
| |
| 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [cache] Hide internal macros incompatible with LLP64. |
| |
| `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and |
| `FTC_IMAGE_TYPE_HASH' are enclosed by |
| FT_CONFIG_OPTION_OLD_INTERNALS and hidden from |
| normal clients. |
| |
| For the history of these macros, see the investigation: |
| http://lists.gnu.org/archive/html/freetype/2010-10/msg00022.html |
| |
| 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist. |
| |
| On LLP64 platforms (e.g. Win64), unsigned long (32-bit) |
| cannot cover the memory address (64-bit). `FT_MEM_VAL' is |
| used for hashing only and not dereferred, so using signed |
| type FT_PtrDist is safe. |
| |
| * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the |

| Replace "%lx" for memory address by "%p", LLP64 platforms. |
| |
| On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover |

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

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

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

| been checked by `FT_STREAM_SEEK', `off2' should be checked |
| similarly. |

| |
| [truetype] Sanitize the broken offsets in `loca'. |
| See Savannah bug #31040. |
| |
| * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the |

| table and pass the limit of `post' table to `load_format_20' and |
| `load_format_25'. |
| (load_format_20): Stop the parsing when we reached at the limit of |
| `post' table. If more glyph names are required, they are filled by |
| NULL names. |

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

| |
| 2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| [truetype] Prevent bytecode reuse after the interpretation error. |
| |
| * src/truetype/ttinterp.c (free_buffer_in_size): New function to |
| free the buffer allocated during the interpretation of this glyph. |
| (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if |
| an error occurs in the bytecode interpretation. The interpretation |
| of invalid bytecode may break the function definitions and referring |
| them in later interpretation is danger. By unsetting these flags, |
| `fpgm' and `prep' tables are executed again in next interpretation. |

| |
| Additional fix for Savannah bug #30306. |
| |
| * src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the |
| POST fragment is 0, the segment is completely ignored. The declared |
| length of the segment is not cared at all. According to Adobe |
| Technical Note 5040, type 0 segment is a comment only and should not |
| be loaded for the interpreter. Reported by Robert Święcki. |

| 2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Initial fix for Savannah bug #30306. |
| |

| Fix Savannah bug #29846. |
| |
| Previously we discovered fonts which used `setcurrentpoint' to set |
| the initial point of a contour to 0,0. This caused FreeType to |
| raise an error, because the `setcurrentpoint' operator is only |
| supposed to be used with the results from an OtherSubr subroutine. |
| |
| This was fixed by simply ignoring the error and carrying on. |
| |
| Now we have found a font which uses setcurrentpoint to actually |
| establish a non-zero point for a contour during the course of a |
| glyph program. 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. |
