73 handle case where `loca' is the last table in the font.
74
75 2010-11-18 Werner Lemberg <wl@gnu.org>
76
77 [sfnt] Ignore all errors while loading `OS/2' table.
78 Suggested by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>.
79
80 * src/sfnt/sfobjs.c (sfnt_load_face): Do it.
81
82 2010-11-18 Johnson Y. Yan <yinsen_yan@foxitsoftware.com>

102
103 2010-11-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
104
105 [UVS] Fix find_variant_selector_charmap(), Savannah bug #31545.
106
107 Since 2010-07-04, find_variant_selector_charmap() returns
108 the first cmap subtable always under rogue-compatible
109 configuration, it causes NULL pointer dereference and
110 make UVS-related functions crashed.
111
112 * src/base/ftobjs.c (Fix find_variant_selector_charmap):
113 Returns UVS cmap correctly.
114
115 2010-11-01 Alexei Podtelezhnikov <apodtele@gmail.com>
116
117 [ftsmooth] Improve rendering.
118
119 * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
120 cubic deviations have been estimated _after_ UPSCALE, whereas
121 conic ones have been evaluated _before_ UPSCALE, which produces
122 inferior rendering results. Fix this.
123 Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has
124 been tested with demo images sent to the mailing list. See
125
126 http://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html

131
132 [ftraster] Minor fixes.
133
134 Reported by Tom Bishop <wenlin@wenlin.com>.
135
136 * src/raster/ftraster.c (ULong): Remove unused typedef.
137 (TWorker): Remove unused variable `precision_mask'.
138
139 2010-10-28 Werner Lemberg <wl@gnu.org>
140
141 [ftraster] Fix rendering.
142
143 Problem reported by Tom Bishop <wenlin@wenlin.com>; see
144 thread starting with
145
146 http://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html
147
148 * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv
149 since the involved multiplication exceeds 32 bits.
150
151 2010-10-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
152
153 Revert a change of `_idx' type in FTC_CACHE_LOOKUP_CMP().
154
155 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert
156 the type of `_idx' from FT_PtrDist (by previous change)
157 to original FT_UFast, to match with FT_CacheRec.
158
159 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
160
161 [cache] Change the hash types to FT_PtrDist.
162
163 On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
164 variables are inappropriate to calculate hash values
165 from the memory address (64-bit). The hash variables
166 are extended from FT_ULong to FT_PtrDist and new
167 hashing macro functions are introduced. The hash
168 values on 16-bit memory platforms are changed, but
169 ILP32 and LP64 are not changed. The hash value in
170 the cache subsystem is not reverted to the memory
171 address, so using signed type FT_PtrDist is safe.
172
173 * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
174 function to replace FTC_FACE_ID_HASH() for portability.
175 * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
176 FTC_FACE_ID_HASH() by _FTC_FACE_ID_HASH().
177 * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
178
179 * src/cache/ftccache.h (FTC_NodeRec): The type of the
180 member `hash' is changed from FT_UInt32 to FT_PtrDist.
181
182 * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
183 argument `hash' is changed from FT_UInt32 to FT_PtrDist.
184 (FTC_Cache_NewNode): Ditto.
185 * src/cache/ftccache.c (ftc_cache_add): Ditto.
186 (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
187 * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
188 * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
189
190 * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
191 of the internal variable `hash' is changed to FT_PtrDist
192 from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
193 (FTC_SBitCache_Lookup): Ditto.
194 (FTC_SBitCache_LookupScaler): Ditto.
195 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
196 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
197 Also the type of the internal variable `_idx' is changed to
198 FT_PtrDist from FT_UFast for better pointer calculation.
199
200 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
201
202 [cache] Hide internal macros incompatible with LLP64.
203
204 FT_POINTER_TO_ULONG(), FTC_FACE_ID_HASH() and
205 FTC_IMAGE_TYPE_HASH() are enclosed by
206 FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
207 normal clients.
208
209 For the history of these macros, see the investigation:
210 http://lists.gnu.org/archive/html/freetype/2010-10/msg00022.html
211
212 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
213
214 Change the type of FT_MEM_VAL() from FT_ULong to FT_PtrDist.
215
216 On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
217 cannot cover the memory address (64-bit). FT_MEM_VAL() is
218 used for hashing only and not dereferred, so using signed
219 type FT_PtrDist is safe.
220
221 * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
222 return value from FT_ULong to FT_PtrDist.
223 (ft_mem_table_resize): The type of hash is changed to
224 FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
225
226 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
227
228 Replace "%lx" for memory address by "%p", LLP64 platforms.
229
230 On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
231 the memory address (64-bit). Also the casts from the pointer
232 type to long int should be removed to preserve the address
233 correctly.
234
235 * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
236 (End_Profile) Ditto.
237 * src/truetype/ttinterp.c (Init_Context): Ditto.
238
239 2010-10-15 Alexei Podtelezhnikov <apodtele@gmail.com>
240
241 Fix thinko in spline flattening.
242
243 FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL.
244
245 * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and
246 replace it everywhere with ONE_PIXEL/8.
247
248 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
249
250 [raccess] Skip unrequired resource access rules by Darwin VFS.
251
252 When a resource fork access rule by Darwin VFS could open the
253 resource fork but no font is found in it, the rest of rules
254 by Darwin VFS are skipped. It reduces the warnings of the
255 deprecated resource fork access method by recent Darwin kernel.
256 Fix MacPorts ticket #18859:
257 http://trac.macports.org/ticket/18859
258
259 * src/base/ftobjs.c (load_face_in_embedded_rfork):
260 When FT_Stream_New() returns FT_Err_Cannot_Open_Stream, it
261 means that the file is possible to be fopen()-ed but zero-sized.
262 Also there is a case that the resource fork is not zero-sized,
263 but no supported font exists in it. If a rule by Darwin VFS
264 falls into such cases, there is no need to try other Darwin VFS
265 rules anymore. Such cases are marked by vfs_rfork_has_no_font.
266 If it is TRUE, the Darwin VFS rules are skipped.
267
268 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
269
270 [raccess] Grouping resource access rules based on Darwin VFS.
271
272 MacOS X/Darwin kernel supports a few tricky methods to access
273 a resource fork via ANSI C or POSIX interface. Current resource
274 fork accessor tries all possible methods to support all kernels.
275 But if a method could open a resource fork but no font is found,
276 there is no need to try other methods older than tested method.
277 To determine whether the rule index is for Darwin VFS, a local
278 function ftrfork.c::raccess_rule_by_darwin_vfs() is introduced.
279 To use this function in ftobjs.c etc but it should be inlined,
280 it is exposed by ftbase.h.
281
282 * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
283 the rules to access the resource fork.
284 (raccess_guess_rec): New structure to bind the rule function and
285 rule enum type.
286 (FT_Raccess_Guess): The list of the rule functions is replaced by
287 (raccess_guess_table): This. This is exposed to be used by other
288 intra module functions.
289 (raccess_rule_by_darwin_vfs): A function to return a boolean
290 if the rule specified by the rule index is based on Darwin VFS.
291
292 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
293
294 Prevent to open a FT_Stream for zero-sized file on non-Unix.
295
296 builds/unix/ftsystem.c prevents to open an useless stream from
297 zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
298 stream drivers for ANSI C, Amiga and VMS return useless streams.
299 For cross-platform consistency, all stream drivers should act
300 same.
301
302 * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
303 file is zero, FT_Err_Cannot_Open_Stream is returned.
304 * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
305 * src/vms/ftsystem.c (FT_Stream_Open): Ditto.
306
307 2010-10-12 Werner Lemberg <wl@gnu.org>
308
309 Fix Savannah bug #31310.
310
311 * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against
312 invalid `runcnt' values.
313
314 2010-10-08 Chris Liddell <chris.liddell@artifex.com>
315
316 Fix Savannah bug #31275.
317
318 * src/sfnt/ttpost.c: Include FT_INTERNAL_DEBUG_H.
319
320 2010-10-06 Werner Lemberg <wl@gnu.org>
321
322 [truetype] Improve error handling of `SHZ' bytecode instruction.
323 Problem reported by Chris Evans <scarybeasts@gmail.com>.
324
325 * src/truetype/ttinterp.c (Ins_SHZ): Check `last_point'.
326
327 2010-10-05 Werner Lemberg <wl@gnu.org>
328
329 Fix Savannah bug #31253.
330 Patch submitted by an anonymous reporter.
331
332 * configure: Use `awk' instead of `sed' to manipulate output of `ls
333 -id'.
334
335 2010-10-03 Werner Lemberg <wl@gnu.org>
336

400 * src/sfnt/ttpost.c (load_format_20): Showing 1 summary message
401 when we fill `post' names by NULL, instead of per-entry message.
402
403 2010-09-20 Graham Asher <graham.asher@btinternet.com>
404 David Bevan <david.bevan@pb.com>
405
406 [smooth] Fix and improve spline flattening.
407
408 This fixes the flattening of cubic, S-shaped curves and speeds up
409 the handling of both the conic and cubic arcs.
410
411 See the discussions on the freetype-devel mailing list in late
412 August and September 2010 for details.
413
414 * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.
415 (TWorker): Remove `conic_level' and `cubic_level' elements.
416 (gray_render_conic): Simplify algorithm.
417 (gray_render_cubic): New algorithm; details are given in the code
418 comments.

420
421 2010-09-19 Werner Lemberg <wl@gnu.org>
422
423 Minor fixes.
424
425 * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'
426 is `FT_UShort'.
427 (cff_index_access_element): Don't use additions in comparison.
428 * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type
429 `FT_Long'.
430 Don't use additions in comparison.

433 `FT_Long'.
434
435 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
436
437 [cff] Truncate the element length at the end of the stream.
438 See Savannah bug #30975.
439
440 * src/cff/cffload.c (cff_index_access_element): `off2', the offset
441 to the next element is truncated at the end of the stream to prevent
442 invalid I/O. As `off1', the offset to the requested element has
443 been checked by FT_STREAM_SEEK(), `off2' should be checked
444 similarly.
445
446 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
447
448 [cff] Ignore CID > 0xFFFFU.
449 See Savannah bug #30975.
450
451 * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
452 greater than 0xFFFFU. CFF font spec does not mention maximum CID in
453 the font, but PostScript and PDF spec define that maximum CID is
454 0xFFFFU.
455
456 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
457
458 [cff] Make trace message in cff_charset_load() verbose.
459 See Savannah bug #30975.
460
461 * src/cff/cffload.c (cff_charset_load): Report the original `nleft'

465
466 [cff] Correct `max_cid' from CID array length to max CID.
467 See Savannah bug #30975.
468
469 * src/cff/cffload.c (cff_charset_compute_cids): Don't increment
470 max_cid after detecting max CID. The array CFF_Charset->cids is
471 allocated by max_cid + 1.
472 (cff_charset_cid_to_gindex): Permit CID is less than or equal to
473 CFF_Charset->max_cid.
474 * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is

479 [truetype] Sanitize the broken offsets in `loca'.
480 See Savannah bug #31040.
481
482 * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
483 offset to the requested entry in `glyf' exceeds the end of the
484 table, return offset=0, length=0. If `pos2', the offset to the next
485 entry in `glyf' exceeds the end of the table, truncate the entry
486 length at the end of `glyf' table.

489
490 [sfnt] Prevent overrunning in `post' table parser.
491 See Savannah bug #31040.
492
493 * src/sfnt/ttpost.c (load_post_names): Get the length of `post'
494 table and pass the limit of `post' table to load_format_20() and
495 load_format_25().
496 (load_format_20): Stop the parsing when we reached at the limit of
497 `post' table. If more glyph names are required, they are filled by
498 NULL names.

501
502 [truetype] Don't duplicate size->twilight structure to be freed.
503 See Savannah bug #31040 for detail.
504
505 * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
506 FT_GlyphZoneRec size->twilight to be freed. If duplicated,
507 FT_FREE() erases the duplicated pointers only and leave original
508 pointers. They can cause the double-free crash when the burst
509 errors occur in TrueType interpreter and free_buffer_in_size() is
510 invoked repeatedly.
511
512 2010-09-15 Werner Lemberg <wl@gnu.org>
513
514 Make bytecode debugging with FontForge work again.
515
516 * src/truetype/ttinterp.c (TT_RunIns): Don't call
517 `free_buffer_in_size' in case of error if a debugger is active.
518
519 2010-09-14 Werner Lemberg <wl@gnu.org>
520
521 Improve tracing messages.
522
523 * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
524 message.
525 * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
526 tracing message.
527 * src/truetype/ttgload.c (tt_loader_init): Add tracing message.
528 * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
529 glyph doesn't fit into a small bitmap container.
530
531 2010-09-13 Werner Lemberg <wl@gnu.org>
532
533 Fix minor issues reported by <muktha.narayan@wipro.com>.
534
535 * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
536 redundant conditional check.
537 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
538 * src/cff/cffload.c (cff_encoding_load): Remove conditional check
539 which always evaluates to `true'.
540 * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
541 Ditto.
542 * src/truetype/ttinterp.c (Ins_IUP): Ditto.
543 * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
544 value is already dereferenced.
545 * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
546
547 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
548
549 Ignore the environmental setting of LIBTOOL.
550 Patch is suggested by Adrian Bunk, to prevent unexpected
551 reflection of environmental LIBTOOL. See:
552 http://savannah.nongnu.org/patch/?7290
553
554 * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
555 $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
556 by default.
557 * configure: When configured for the building out of source tee,
558 FT_LIBTOOL_DIR is set to $(OBJ_DIR).
559
560 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
561
562 [truetype] Decrease the trace level catching the interpreter error.
563
564 * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
565 showing the error when the interpreter returns with an error,
566 from FT_TRACE7() to FT_TRACE1().
567
568 2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
569
570 [truetype] Prevent bytecode reuse after the interpretation error.
571
572 * src/truetype/ttinterp.c (free_buffer_in_size): New function to
573 free the buffer allocated during the interpretation of this glyph.
574 (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
575 an error occurs in the bytecode interpretation. The interpretation
576 of invalid bytecode may break the function definitions and referring
577 them in later interpretation is danger. By unsetting these flags,
578 `fpgm' and `prep' tables are executed again in next interpretation.
579
580 This fixes Savannah bug #30798, reported by Robert Święcki.
581
582 2010-08-29 Werner Lemberg <wl@gnu.org>

584 [ftraster] Pacify compiler.
585

588
589 2010-08-29 Werner Lemberg <wl@gnu.org>
590
591 [cff] Allow SIDs >= 65000.
592
593 * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
594 The threshold for SIDs is not applicable here. I misinterpreted the
595 `SID values 65000 and above are available for implementation use'
596 sentence in the CFF specification.

601
602 Force hinting when the font lacks its familyname.
603
604 In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
605 stream may lack `name' table because they are not required. Hinting
606 for nameless fonts is safer for PDFs including embedded Chinese
607 fonts. Written by David Bevan, see:

611
612 * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by
613 nameless font is given, TRUE is returned to enable hinting.
614
615 2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
616
617 Register yet another tricky TrueType font.
618

670
671 * src/base/ftobjs.c (FT_Done_Library): Specify the order of font
672 drivers during the face closing process. Type42 faces should be
673 closed before TrueType faces, because a Type42 face refers to
674 another internal TrueType face which is created from sfnt[] array on

1361 Fix Savannah bug #29846.
1362
1363 Previously we discovered fonts which used `setcurrentpoint' to set
1364 the initial point of a contour to 0,0. This caused FreeType to
1365 raise an error, because the `setcurrentpoint' operator is only
1366 supposed to be used with the results from an OtherSubr subroutine.
1367
1368 This was fixed by simply ignoring the error and carrying on.
1369
1370 Now we have found a font which uses setcurrentpoint to actually
1371 establish a non-zero point for a contour during the course of a
1372 glyph program. FWIW, these files may be produced by an application
1373 called `Intaglio' on the Mac, when converting TrueType fonts to
1374 Type 1.
1375
1376 The fix allows the new invalid behaviour, the old invalid behaviour
1377 and real proper usage of the operator to work the same way as Adobe
1378 interpreters apparently do.
1379
1380 (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
1381 two elements of the stack to establish unconditionally the current x
1382 and y coordinates.
1383
1384 Make the `flex' subroutine handling (OtherSubr 0) put the current
1385 x,y coordinates onto the stack, instead of two dummy uninitialised
1386 values.
