[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: |
|

|
|
|
* 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. |
|
|
|

|
|
|
[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'. |

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. |
|

[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.c (FTC_GCache_Lookup): Ditto. |
|
|
|
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type |

|
Also the type of the internal variable `_idx' is changed to |

[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. |

|
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 |
|
return value from FT_ULong to FT_PtrDist. |
|
(ft_mem_table_resize): The type of hash is changed to |
|
FT_PtrDist. (ft_mem_table_get_nodep): Ditto. |
|
|
|
2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
|
|
|
Replace "%lx" for memory address by "%p", LLP64 platforms. |
|
|
|
On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover |
|
the memory address (64-bit). Also the casts from the pointer |
|
type to long int should be removed to preserve the address |
|
correctly. |
|
|
|
* src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p". |
|
(End_Profile) Ditto. |
|
* src/truetype/ttinterp.c (Init_Context): Ditto. |

[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. |

[truetype] Sanitize the broken offsets in `loca'. |
|
See Savannah bug #31040. |
|
|

* src/truetype/ttpload.c (tt_face_get_location): If `pos1', the |
|
offset to the requested entry in `glyf' exceeds the end of the |
|

[sfnt] Prevent overrunning in `post' table parser. |
|
See Savannah bug #31040. |
|
|
|
* src/sfnt/ttpost.c (load_post_names): Get the length of `post' |
|
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 |

[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. |
|
|
|
2010-09-15 Werner Lemberg <wl@gnu.org> |

|
Make bytecode debugging with FontForge work again. |

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

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

|
|
|
* src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20: |

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

2010-05-10 Ken Sharp <ken.sharp@artifex.com> |
|
|
|
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. |

Improve CFF string (especially glyphname) lookup performance. |
|
|
|
We do this by avoiding memory allocation and file I/O. This is |
|
Savannah patch #7104. |
|
|
|
* src/cff/cfftypes.h: Include PS cmaps service and |
|
FT_INTERNAL_POSTSCRIPT_HINTS_H. |
|
(CFF_SubFontRec): Remove `num_local_subrs'. |
|
(CFF_FontRec): Add `num_strings', `strings', and `string_pool' |
|
fields. |
|
Remove `string_index' and `num_global_subrs' fields. |
|
Use real types instead of `void' for `pshinter' and `psnames' fields. |
|
|
|
* src/cff/cffload.c: Don't include PS cmaps service. |
|
(cff_index_get_pointers): Add `pool' parameter which allows to |
|
insert an extra NUL character for each String INDEX entry. |
|
(cff_index_get_name): Make it a local function. |
|
(cff_index_get_string): New function. |
|
(cff_subfont_load): Updated. |
|
(cff_font_load): Initialize `num_strings', `strings', and |
|
`string_pool' fields in the `CFF_FontRec' structure. |
|
(cff_index_get_sid_string): Use `cff_index_get_string' instead of |
|
`cff_index_get_name'. |
|
(cff_font_done): Updated. |
|
|
|
* src/cff/cffload.h: Don't include PS cmaps service. |
|
(cff_index_get_string): Added. |
|
(cff_index_get_sid_string): Updated. |
|
|
|
* src/cff/cffobjs.c: Don't include PS cmaps service and |
|
FT_INTERNAL_POSTSCRIPT_HINTS_H. |
|
(cff_size_get_globals_funcs, cff_slot_init): Updated. |
|
(cff_face_init): Follow `cff_index_get_name', |
|
`cff_index_get_string', and `cff_index_get_sid_string' changes. |
|
|
|
* src/cff/cffcmap.c (cff_sid_free_glyph_name): Removed. |
|
(cff_sid_to_glyph_name): Use `cff_index_get_cid_string'. |
|
(cff_cmap_unicode_init): Updated. |
|
|
|
* src/cff/cffdrivr.c: Don't include PS cmap service. |
|
(cff_get_glyph_name): Avoid unnecessary lookup for POSTSCRIPT_CMAPS |
|
service. |
|
(cff_get_glyph_name, cff_ps_get_font_info, cff_get_ros): Follow API |
|
`cff_index_get_sid_string' change. |
|
(cff_get_name_index): Use `cff_index_get_string' instead of |
|
`cff_index_get_name'. |
|
|
|

|
Simplify code. |
|
Suggested by Behdad. |
|
|
|
* src/base/ftobjs.c (FT_Get_First_Char): Don't use a loop since we |
|
call FT_Get_Next_Char anyway if necessary. |
|
|
|

|
|
|
Improve handling of invalid glyph indices in char->index functions. |
|
|
|
* src/base/ftobjs.c (FT_Get_First_Char, FT_Get_Next_Char): Use a |
|
loop. |

Fix Savannah bug #28905. |
|
|
|
Initialize phantom points before calling the incremental interface |
|
to update glyph metrics. |
|
|
|
* src/truetype/ttgload.c (tt_get_metrics_incr_overrides) |
|
[FT_CONFIG_OPTION_INCREMENTAL]: New function, split off from... |
|
(tt_get_metrics): This. |
|
Updated. |
|
(load_truetype_glyph): Use tt_get_metrics_incr_overrides. |
