[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. |

[gxvalid] Cleanup. |
|
|
|
Some invalid, overrunning, unrecommended non-zero values |
|
are cared in paranoid validation mode only. There are |
|
many lines looking like: |
|
|
|
if ( valid->root->level >= FT_VALIDATE_PARANOID ) |
|
FT_INVALID_xxx; |
|
|
|
To simplify them, GXV_SET_ERR_IF_PARANOID( err ) is |
|
introduced for more paranoid validation in future. |
|
|
|
* src/gxvalid/gxvcommn.h (IS_PARANOID_VALIDATION): |
|
New macro to assure valid->root->level is more or |
|
equal to FT_VALIDATE_PARANOID. (GXV_SET_ERR_IF_PARANOID): |
|
New macro to raise an error if in paranoid validation. |
|
* src/gxvalid/gxvcommn.c: Use GXV_SET_ERR_IF_PARANOID(). |
|
* src/gxvalid/gxvfeat.c: Ditto. |
|
* src/gxvalid/gxvjust.c: Ditto. |

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. |

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 |

|
|
|
* 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 |

[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. |
|
|

|
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. |

[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. |

|
|
|
[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) |

[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. |

* 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. |

|
|
|
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. |
