77 * src/cff/cf2intrp.c (cf2_interpT2CharString) <default>: Force
78 unsigned for computations.
79 * src/cff/cffgload.c (cff_decoder_parse_charstrings): Ditto.

83
84 2013-05-04 Werner Lemberg <wl@gnu.org>
85
86 [cff] Make Adobe CFF engine work correctly on 64bit hosts.
87
88 Reported by numerous people on the `freetype-devel' list. Without
89 this fix, glyphs aren't properly aligned on a common baseline.
90
91 On 64bit systems, `FT_Pos' expands to `long int', having a width of
92 64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on
93 64bit hosts also. Wrong casts filled up the blues arrays with
94 incorrect values. Note that all blues values are accessed with the
95 `cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
96
97 * src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
98 cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
99 `data', not `CF2_Fixed'.
100 * src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,
101 cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.
102 * src/cff/cf2blues.c (cf2_blues_init): Updated.
103
104 2013-05-04 Werner Lemberg <wl@gnu.org>
105
106 More fixes for clang's `sanitize' feature.
107
108 * src/base/ftcalc.c (FT_DivFix): Use unsigned values for
109 computations which use the left shift operator and convert to signed
110 as the last step.
111 * src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,
112 FT_Vector_Length, FT_Vector_Polarize): Ditto.
113
114 * src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify.
115 * src/cff/cffload.c (cff_subfont_load): Fix constant.
116 * src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed,
117 cff_parse_fixed_dynamic): Use unsigned values for computations which
118 use the left shift operator and convert to signed as the last step.
119
120 * src/cid/cidload.c (cid_get_offset): Ditto.
121
122 * src/psaux/psconv.c (PS_Conv_ToFixed): Ditto.
123 * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto.
124
125 * src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
126
127 2013-05-04 Werner Lemberg <wl@gnu.org>
128
129 Fix errors reported by clang's `sanitize' feature.
130
131 * include/freetype/internal/ftstream.h: Simplify and fix integer
132 extraction macros.
133 (FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32,
134 FT_INT8_I32, FT_INT8_U32): Removed.
135 (FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE,
136 FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for
137 computations and convert to signed as the last step.
138
139 * src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,
140 cf2_fracToFixed): Avoid shifts of negative values.
141 (cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,
142 unused.
143
144 * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,
145 default>: Use unsigned values for computations and convert to signed
146 as the last step.
147 Use proper types in tracing messages.
148
149 * src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned
150 values for computation of operands and convert to signed as the last
151 step.
152 Use proper type in tracing message.
153
154 2013-05-03 Werner Lemberg <wl@gnu.org>
155

166
167 2013-04-13 Werner Lemberg <wl@gnu.org>
168
169 [cff] Add a new Type 2 interpreter and hinter.
170
171 This work, written by Dave Arnold <darnold@adobe.com> and fully
172 integrated into FreeType by me, is a donation by Adobe in
173 collaboration with Google. It is vastly superior to the old CFF
174 engine, and it will replace it soon. Right now, it is still off by
175 default, and you have to explicitly select it using the new
176 `hinting-engine' property of the cff driver.
177
178 For convenience, (most of) the new files are committed separately.
179
180 * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
181 * include/freetype/ftcffdrv.h: New file to access CFF driver
182 properties.
183 * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
184 code.
185 * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
186 and `cf2interp'.
187
188 * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
189 * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
190 and `no_stem_darkening'.
191 * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.
192
193 * src/cff/cff.c: Include new files.
194 * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
195 `hinting-engine' and `no-stem-darkening' properties (only the Adobe
196 engine listens to them).
197 * src/cff/cffgload.c: Include `cf2ft.h'.
198 (cff_decoder_prepare): Initialize `current_subfont'.
199 (cff_build_add_point): Handle Adobe engine which uses 16.16
200 coordinates.
201 (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
202 separately.
203 Choose rendering engine based on `hinting_engine' property.
204 * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
205 engine.
206 * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
207 (cff_driver_init): Set default property values.
208
209 * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.
210
211 * src/cff/cf2*.*: New files, containing the Adobe engine.
212
213 2013-04-12 Werner Lemberg <wl@gnu.org>
214
215 [cff] Minor code administration issues.
216
217 * src/cff/cffgload.c (check_points): Rename to...
218 (cff_check_points): ...this and make it FT_LOCAL.
219 (cff_builder_add_point, cff_builder_add_point1,
220 cff_builder_start_point, cff_builder_close_contour,
221 cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data,
222 cff_free_glyph_data): Make them FT_LOCAL.
223
224 * src/cff/cffgload.h: Updated.
225
226 2013-04-12 Werner Lemberg <wl@gnu.org>
227
228 Add output bitmap checksums.
229
230 Use `FT2_DEBUG=bitmap:3' for tracing.
231
232 * src/base/md5.c, src/base/md5.h: New files, taken from
233
234 http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5
235
236 * include/freetype/internal/fttrace.h: Add `bitmap'.
237
238 * src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'
239
240 (FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,
241 convert resulting bitmap to a uniform format and compute a checksum.
242 Use `bitmap' category for the tracing message.
243
244 * src/base/rules.mk (BASE_H): Updated.
245
246 * docs/LICENSE.TXT: Updated.
247
248 2013-04-12 Werner Lemberg <wl@gnu.org>
249
250 [cff] Add framework for CFF properties.
251
252 * include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7):
253 New macro.
254
255 * src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H.
256 (cff_property_set, cff_property_get): New functions, still empty.
257 Define `cff_service_properties' service.
258 Update `cff_services'.
259
260 * src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.
261 (CFF_SERVICE_PROPERTIES_GET): New macro.

263
264 2013-04-03 Werner Lemberg <wl@gnu.org>
265
266 [bdf] Fix Savannah bug #38589.
267
268 * src/bdf/bdflib.c (_bdf_readstream): Thinko.
269
270 2013-03-31 Werner Lemberg <wl@gnu.org>
271
272 * configure: Use egrep, not grep.
273
274 Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
275
276 2013-03-29 Werner Lemberg <wl@gnu.org>
277
278 * include/freetype/ftlcdfil.h: Add description of color filtering.
279
280 Based on a contribution from Antti S. Lankila <alankila@bel.fi>
281 (Savannah bug #38607).
282
283 2013-03-23 Werner Lemberg <wl@gnu.org>
284
285 [autofit] Minor.
286
287 * src/autofit/afmodule.c (af_property_set): Typo.
288 (af_autofitter_init, af_autofitter_done): Use cast.
289
290 2013-03-21 Werner Lemberg <wl@gnu.org>
291
292 * configure: Automatically test for `gmake' also.
293
294 Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
295
296 2013-03-21 Peter Breitenlohner <peb@mppmu.mpg.de>
297
298 Respect CONFIG_SHELL from the environment.
299
300 Some large packages using FreeType have to use a broken (deficient)
301 /bin/sh. The configure scripts (as generated by Autoconf) are
302 clever enough to find a better shell and put that one into the
303 environment variable CONFIG_SHELL. If that environment variable is
304 already set the script skips the test and assumes to be already
305 running under a good shell.
306
307 * builds/unix/detect.mk: Honour CONFIG_SHELL.
308 * builds/unix/unix-def.in (SHELL): Define.
309
310 2013-03-21 Werner Lemberg <wl@gnu.org>
311
312 Fix Savannah patch #7971.
313
314 * configure: Handle MAKE environment variable also.
315
316 2013-03-17 Werner Lemberg <wl@gnu.org>
317
318 Fix Savannah bug #38538.
319
320 * builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,
321 builds/wince/ftdebug.c (FT_Throw): Add function.
322
323 2013-03-17 Werner Lemberg <wl@gnu.org>
324
325 [raster] Remove dead code.
326
327 * src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)
328 src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
329
330 2013-03-17 Werner Lemberg <wl@gnu.org>
331
332 * src/pshinter/pshpic.h (GET_PIC): Use correct container.
333
334 2013-03-15 Werner Lemberg <wl@gnu.org>
335
336 * include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
337
338 The previous version was not backwards compatible. Reported by
339 Behdad.
340
341 2013-03-14 Werner Lemberg <wl@gnu.org>
342
343 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
344
345 FT_Err_XXX and friends are no longer directly used in the source
346 code.
347
348 2013-03-14 Werner Lemberg <wl@gnu.org>
349
350 New error management macros.
351
352 * include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
353 * include/freetype/fttypes.h: ... this file.
354 (FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
355 macros.
356
357 * include/freetype/freetype.h: Updated.
358
359 2013-03-14 Werner Lemberg <wl@gnu.org>
360
361 */*: Use FT_Err_Ok only.
362
363 This is a purely mechanical conversion.
364
365 2013-03-14 Werner Lemberg <wl@gnu.org>
366
367 */*: Use `FT_THROW'.
368
369 This is essentially a mechanical conversion, adding inclusion of
370 `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
371 stand-alone compiling modes of the rasterizer modules.
372
373 To convert the remaining occurrences of FT_Err_XXX and friends it is
374 necessary to rewrite the code. Note, however, that it doesn't harm
375 if some cases are not handled since FT_THROW is a no-op.
376
377 2013-03-13 Werner Lemberg <wl@gnu.org>
378
379 Introduce `FT_THROW' macro.
380
381 The idea is to replace code like
382
383 return FT_Err_Foo_Bar;
384
385 or
386
387 return CFF_Err_Foo_Bar;
388
389 with
390
391 return FT_THROW( Foo_Bar );
392
393 The FT_THROW macro has two functions:
394
395 . It hides the module specific prefix.
396
397 . In debug mode, it calls the empty function `FT_Throw' which can
398 be thus used to set a breakpoint.
399
400 * include/freetype/internal/ftdebug.h (FT_THROW): New macro.
401 (FT_Throw): New prototype.
402 * src/base/ftdebug.c (FT_Throw): New function.
403
404 2013-03-12 Werner Lemberg <wl@gnu.org>
405
406 Remove `FT_KEEP_ERR_PREFIX'.
407
408 The idea is to always have FT_ERR_PREFIX available internally.
409
410 * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
411 undefinition of FT_ERR_PREFIX
412
413 * src/gxvalid/gxverror.h, src/otvalid/otverror.h,
414 src/sfnt/sferrors.h: Updated.
415
416 2013-03-11 Werner Lemberg <wl@gnu.org>
417
418 [gxvalid] Fix module error.
419
420 * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as
421 FT_Mod_Err_GXvalid.
422 * include/freetype/ftmoderr.h: Add module error for `GXvalid'.
423
424 2013-03-11 Werner Lemberg <wl@gnu.org>
425
426 Always use module related error codes.
427
428 * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c
429 (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use
430 `FT_ERROR_BASE'.
431
432 * src/type1/t1load.c (parse_encoding): Use
433 T1_Err_Unknown_File_Format.
434
435 2013-03-08 Werner Lemberg <wl@gnu.org>
436
437 [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.
438
439 Problem reported by Khaled Hosny <khaledhosny@eglug.org>.
440
441 * src/cff/cffgload.c (cff_slot_load): Implement it.
442
443 2013-02-23 Alexei Podtelezhnikov <apodtele@gmail.com>
444
445 [base] Fix commit ab02d9e8.
446
447 * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.
448
449 2013-02-19 Alexei Podtelezhnikov <apodtele@gmail.com>
450
451 [base] New bisecting BBox_Cubic_Check (disabled).
452
453 * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm
454 for extremum search built around simple condition that defines
455 which half contains the extremum.
456
457 2013-02-18 Alexei Podtelezhnikov <apodtele@gmail.com>
458
459 [tools] Update BBox testing tool.
460
461 * src/tools/test_bbox.c: Add another cubic outline with exact BBox.
462 (REPEAT): Increase the number of benchmarking cycles.
463 (profile_outline): Tweak output formatting.
464
465 2013-02-02 Werner Lemberg <wl@gnu.org>
466
467 Fix Savannah bug #38235.
468
469 * builds/unix/configure.raw: Don't generate `freetype-config' and
470 `freetype.pc'.
471
472 * builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,
473 build_libtool_libs, ft_version): New variables to be substituted.
474 (freetype-config, freetype.pc): New rules to generate those files.
475
476 * builds/unix/freetype-config.in: Remove code for handling `rpath'.
477 The use of $rpath has been accidentally removed in a patch from
478 2009-12-22, and apparently noone has missed it since.
479 Use `%' instead of `@' as a variable substitution marker.
480 Use quotes.
481
482 * builds/unix/freetype.in: Use `%' instead of `@' as a variable
483 substitution marker.
484 Use quotes.
485
486 2013-02-07 Werner Lemberg <wl@gnu.org>
487
488 * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
489
490 BTW, Greg agrees that the OpenType specification is missing the list
491 of GS variables which will always be reset to the default values
492 after the `prep' table has been executed.
493
494 2013-02-06 Werner Lemberg <wl@gnu.org>
495
496 * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
497
498 Up to now, we simply took a snapshot of the Graphics State after the
499 `prep' table has been executed, and right before a glyph's bytecode
500 was run it got reloaded. However, as Greg Hitchcock has told us in
501 private communication, reference points get reset to zero in the MS
502 rasterizer and we follow in due course. While reasonable, this is
503 undocumented behaviour.
504
505 Most notably, this fixes the rendering of Arial's `x' glyph in
506 subpixel hinting mode.

640 [sfnt] Fix broken pointer overflow checks.
641
642 Many compilers such as gcc and clang optimize away pointer overflow
643 checks `p + n < p', because pointer overflow is undefined behavior.
644 Use a safe form `n > p_limit - p' instead.
645
646 Also avoid possible integer overflow issues, for example, using
647 `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2'
648 given a large `num_glyphs'.

746
747 [truetype] Improve sub-pixel code.
748
749 This patches fixes many issues with the ttsubpix implementation.
750
751 1. Data tables are defined, instead of declared, in the header, and
752 thus copied into each source file that includes it.
753
754 2. These tables were defined as global, mutable, visible variables,
755 and thus costing private RAM to every process that loads the
756 library (> 50 KB / process, this is huge!).
757
758 Additionally, this also made the library export the symbols
759 completely needlessly.
760
761 3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
762
763 Note that this doesn't try to fix the incredibly inefficient storage
764 format for the data tables used by the code. This one will require
765 another pass in the future.
766
767 * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS):
768 Renamed to...
769 (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This.
770 Update all users.

772 (SPH_TweakRule, SPH_ScaleRule): Decorate with `const' where
773 appropriate.

782
783 * src/truetype/ttsubpic.c: This file and decorate them with `static'
784 and `const' where appropriate.

791
792 [truetype] Improve accuracy of normalization of short vectors.
793
794 Unit vector components are stored as 2.14 fixed-point numbers. In
795 order to calculate all 14 bits accurately, a short vector to be
796 normalized has to be upscaled to at least 14 bits before its length
797 is calculated. This has been safe since accurate CORDIC algorithms
798 were adopted.
799
800 * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000.
801
802 2013-01-12 Alexei Podtelezhnikov <apodtele@gmail.com>
803
804 [truetype] Kill very old vector normalization hacks.
805
806 Back in the days, vector length calculations were not very accurate
807 and the vector normalization function, Normalize, had to meticulously
808 correct the errors for long vectors [commit b7ef2b096867]. It was no
809 longer necessary after accurate CORDIC algorithms were adopted, but
810 the code remained. It is time to kill it.
811
812 * src/truetype/ttinterp.c (Normalize): Remove error compensation.
813 (TT_VecLen): Remove any mention of old less accurate implementation.
814
815 2013-01-11 Werner Lemberg <wl@gnu.org>

863
864 [base] Reduce trigonometric algorithms.
865
866 After we get within 45 degrees by means of true 90-degree rotations,
867 we can remove initial 45-degree CORDIC iteration and start from

954 [base] Improve trigonometric core.
955
956 FreeType used to rely on a 24-step iteration CORDIC algorithm to
957 calculate trigonometric functions and rotate vectors. It turns out
958 that once the vector is in the right half-plane, the initial rotation
959 by 63 degrees is not necessary. The algorithm is perfectly capable
960 to converge to any angle starting from the second 45 degree rotation.
961 This patch removes the first rotation and makes it a 23-step CORDIC
962 algorithm.
963
964 * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro
965 values.

997
998 2012-12-16 Werner Lemberg <wl@gnu.org>

1000 Various compiler warning fixes.
1001
1002 * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use
1003 `logical not' operator instead of negation. The idea is that `~'
1004 returns exactly the data type enforced by the cast to a pointer (be
1005 it 32bit or 64bit or whatever), while a negative integer has not
1006 this flexibility.
1007 * src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto.
1008 * src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto.
1009 * src/type/t1load.c (T1_Get_MM_Var): Ditto.
1010 (parse_blend_axis_types): Use cast.

1033 * src/truetype/ttobjs.h: Updated.
1034 (TT_SizeRec): Add ttfautohinted variable.
1035
1036 * src/truetype/ttinterp.c: Updated.
1037 (Ins_FDEF): Rework code to fix bugs and add more detection.
1038 (Ins_CALL): Remove unused code.

1042 (Ins_MIRP): Don't round x in cut-in calculation. Add logic to handle
1043 ttfautohinted fonts.

1052
1053 [base] Fix 11-year old bug.
1054
1055 Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has
1056 always been slightly less than the correct value, which has been
1057 given in the comment as a hexadecimal. As a result, vector lengths
1058 were underestimated and rotated vectors were shortened.
1059
1060 * src/base/fttrigon.c (FT_TRIG_SCALE): Fix macro value.
1061
1062 2012-12-15 Werner Lemberg <wl@gnu.org>
1063

1074 size for checking `glyph_enc'.
1075
1076 2012-12-15 Werner Lemberg <wl@gnu.org>
1077
1078 [bdf] Fix Savannah bug #37905.
1079
1080 * src/bdf/bdflib.c (_bdf_parse_start) <STARTPROPERTIES>: Reset
1081 `props_size' to zero in case of allocation error; this value gets
1082 used in a loop in `bdf_free_font'.
1083
1084 2012-12-10 Alexei Podtelezhnikov <apodtele@gmail.com>
1085
1086 [truetype] Scale F_dot_P down.
1087
1088 The dot product between freeVector and projVector or cosine of
1089 the angle between these FT_F2Dot14 unit vectors used to be scaled up
1090 by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
1091 This patch scales the value down by 2^14 instead, which simplifies
1092 its use throughout the bytecode interpreter.
1093
1094 This does not lead to the loss of precision because the lower bits
1095 are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
1096 for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
1097 These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
1098 rounding and F_dot_P is assigned 0x26660000. The lower bits were
1099 already lost while rounding the unit vector components.
1100
1101 Besides code simplification, this change can lead to better
1102 performance when FT_MulDiv with the scaled-down F_dot_P is less
1103 likely to use the costly 64-bit path. We are not changing the type
1104 of F_dot_P to FT_F2Dot14 at this point.
1105
1106 * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
1107 bits and modify its use accordingly.
1108 (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
1109 the use of F_dot_P field.
1110 * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
1111 assignment of F_dot_P to its theoretical maximum in case we decide
1112 to scale back its type later.
1113

1385
1386 Remove useless `rm' detection.
1387
1388 `rm -f' is directly used in the `configure' script created by

1404
1405 * src/autofit/aftypes.h (AF_SCRIPT):

1407 as a bit mask.
1408

1425 [autofit] Implement Infinality's `increase glyph heights'.
1426
1427 This is an improved version of a similar fix contained in the
1428 so-called `Infinality patch', taken from
1429
1430 http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
1431
1432 which addresses various enhancements of the auto-hinter. Without
1433 properties to control a module's metadata it wasn't possible to
1434 adapt the patches because everything was originally controlled by
1435 environment variables which I consider not suitable in general.
1436
1437 A patch to control `increase_x_height' follows.
1438
1439 * src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN,
1440 AF_PROP_INCREASE_X_HEIGHT_MAX): New macros.
1441 (AF_FaceGlobalsRec): Add `increase_x_height' member.

1456 (AF_ScriptMetricsRec): Add `globals' member.
1457
1458 * src/autofit/afglobal.c (af_face_globals_new,
1459 af_face_globals_compute_script_coverage,

1860 Fix `checking if gcc static flag -static works' test.
1861
1862 On my linux build tree, I receive yes answer in in every package I
1863 build except freetype for this test checking if gcc static flag
1864 `-static' works
1865
1866 On freetype, no is received, unless bzip2 and zlib are disabled using
1867
1868 ./configure --without-bzip2 --without-zlib
1869
1870 The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to
1871 LDFLAGS and this broke static flag test.

1920 elsewhere also.

1933 [truetype] Remove unused rounding functionality.
1934
1935 The subpixel hinting patch contained the concept of an adjustable
1936 number of gridlines per pixel. This is no longer used due to x
1937 being completely ignored instead. This will return some of the
1938 code to its existing state prior to the original Infinality
1939 commit.
1940
1941 * include/freetype/internal/ftobjs.h (FT_PIX_FLOOR_GRID,

1948 pixel.

1954 rounding function. Remove gridlines_per_pixel. Create a local
1955 variable to store control value cutin. Simplify the conditional for
1956 ignore_x_mode. Adjust rounding calls to pass only two values.

1969 [truetype] Support subpixel hinting.
1970
1971 This is the large, famous `Infinality' patch to support ClearType
1972 bytecode which has been available from
1973 http://www.infinality.net/blog/ for some time, and which has been
1974 refined over the last years. While still experimental, it is now
1975 mature enough to be included directly into FreeType.
1976
1977 Most of the code is based on the ClearType whitepaper written by
1978 Greg Hitchcock
1979
1980 http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
1981
1982 which gives a detailed overview of the necessary changes to the
1983 Microsoft rasterizer so that older fonts are supported. However, a
1984 lot of details are still missing, and this patches provides a
1985 framework to easily handle rendering issues down to the glyph level
1986 of certain fonts.
1987
1988 Note that ClearType support is not completely implemented! In
1989 particular, full support for the options `compatible_widths',
1990 `symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
1991 instruction) is missing.
1992
1993 * src/truetype/ttsubpix.c: New file, providing code to handle
1994 `tweaks', this is, rules for certain glyphs in certain fonts
1995 (including wildcards) which need a special treatment.
1996
1997 * src/truetype/ttsubpix.h: New file, holding the tweaking rules.
1998
1999 * include/freetype/config/ftoption.h, src/devel/ftoption.h

2012 (TT_Hint_Glyph): Call `FT_Outline_EmboldenXY' if necessary.
2013 (TT_Process_Simple_Glyph): Compensate emboldening if necessary.

2242 [autofit] Return correct linear advance width values.
2243
2244 This was quite a subtle bug which accidentally showed up with glyph
2245 `afii10023' of arial.ttf (version 2.76). This glyph is a composite;
2246 the first component, `E', has an advance width of 1366 font units,
2247 while the advance width of the composite itself (which looks like
2248 uppercase `E' with dieresis) is 1367 font units. I think this is
2249 actually a bug in the font itself, because there is no reason that
2250 this glyph has not the same width as uppercase `E' without the
2251 dieresis. Anyway, it helped identify this problem.
2252
2253 Using the TrueType hinter, the correct value (1367) of `afii10023'
2254 was returned, but the autohinter mysteriously returned 1366.
2255
2256 Digging in the code showed that the autohinter recursively calls
2257 FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
2258 flag. However, the `linearHoriAdvance' field is still returned as a
2259 scaled value. To avoid scaling twice, the old code in autofit reset
2260 `linearHoriAdvance', using the `horiAdvance' field. This seemed to
2261 work since FT_LOAD_NO_SCALE was in use, but it failed actually,
2262 because `horiAdvance' is defined as the distance of the first
2263 subglyph's phantom points, which in turn are initialized using the
2264 advance width of the first subglyph. And as the given example
2265 shows, these widths can differ.
2266
2267 * src/autofit/afloader.c (af_loader_load_g): Temporarily set
2268 FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
2269 values for the linear advance widths.

2273 [truetype] Fix SSW instruction.
2274
2275 * src/truetype/ttinterp.c (DO_SSW): SSW *does* use font units. For
2276 verification, it took some time to find a font which actually uses
2277 this instruction.

2365 [bdf] Fix Savannah bug #35656.
2366
2367 * src/bdf/bdflib.c (_bdf_parse_glyphs) <_BDF_BITMAP>: Check validity
2368 of nibble characters instead of accessing `a2i' array.

2385 [psaux] Fix Savannah bug #35657.
2386
2387 If in function `skip_spaces' the routine `skip_comment' comes to the
2388 end of buffer, `cur' is still increased by one, so we need to check
2389 for `p >= limit' and not `p == limit'.
2390
2391 * src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
2392 PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.
2393
2394 2012-03-01 Werner Lemberg <wl@gnu.org>

2410 2012-03-01 Werner Lemberg <wl@gnu.org>
2411
2412 [bdf] Fix Savannah bug #35641.
2413
2414 * src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if
2415 _BDF_ENCODING isn't set. We need this because access to the `glyph'
2416 variable might be undefined otherwise.

2445 twilight zone.
2446
2447 2012-02-29 Alexei Podtelezhnikov <apodtele@gmail.com>

2677 [raccess] Modify for PIC build.
2678
2679 Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
2680 http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html
2681
2682 Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
2683 are renamed with `ft_' suffixes.
2684
2685 * src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
2686 to `ft_raccess_rule_by_darwin_vfs()'.
2687 * src/base/ftobjs.c: Ditto.
2688
2689 * src/base/ftrfork.c: Declarations of FT_RFork_Rule,
2690 raccess_guess_rec, are moved to...
2691 * include/freetype/internal/ftrfork.h: Here.
2692
2693 * include/freetype/internal/ftrfork.h:
2694 FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
2695 to replace raccess_guess_table[] in both of PIC and non-PIC
2696 modes.
2697 * src/base/ftrfork.c: raccess_guess_table[] array is rewritten
2698 by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.
2699
2700 * src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
2701 storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
2702 the function pointer from `ft_raccess_guess_table' storage in
2703 `BasePIC' structure.
2704 * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
2705 FT_RACCESS_GUESS_TABLE_GET.
2706 (raccess_get_rule_type_from_rule_index): Add `library' as the
2707 first argument to the function, to retrieve the storage of
2708 `ft_raccess_guess_table' from it. Also `raccess_guess_table'
2709 is replaced by FT_RACCESS_GUESS_TABLE_GET.
2710 (ft_raccess_rule_by_darwin_vfs): Ditto.

2732
2733 [autofit] Fix the inclusion of `aflatin2.h' in PIC file.
2734
2735 * src/autofit/afpic.c: Include `aflatin2.h' when
2736 FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
2737 Unconditionally inclusion causes declared but unimplemented
2738 warning by GCC 4.6.
2739
2740 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2741
2742 [cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
2743
2744 * src/cff/cffpic.c: The declarations of
2745 FT_Init_Class_cff_cmap_encoding_class_rec() and
2746 FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
2747 They can be obtained by the inclusion of cffcmap.h.
2748 cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
2749 FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
2750
2751 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2752
2753 Fix redundant declaration warning in PIC mode.
2754
2755 Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
2756 designed to declare xxx_pic_{free,init} by themselves.
2757 Because these macros are used at the end of the module
2758 interface (e.g. ttdriver.c) and the wrapper source to build
2759 a module as a single object (e.g. truetype.c) includes
2760 the PIC file (e.g. ttpic.c) before the module interface,
2761 these macros are expanded AFTER xxx_pic_{free,init} body
2762 when the modules are built as single object.
2763 The declaration after the implementation causes the redundant
2764 declaration warnings, so the declarations are moved to module
2765 PIC headers (e.g. ttpic.h). Separating to other header files
2766 are needed for multi build.
2767
2768 * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
2769 Remove class_##_pic_free and class_##_pic_init declarations.
2770 * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
2771 FT_DEFINE_MODULE): Ditto.
2772
2773 * src/base/basepic.h: Insert a comment and fix coding style.
2774 * src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
2775 init}.
2776 * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
2777 * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
2778 init}.
2779 * src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
2780 init}.
2781 * src/raster/rastpic.h: Declare
2782 ft_raster{1,5}_renderer_class_pic_{free,init}
2783 * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
2784 * src/smooth/ftspic.h: Declare
2785 ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
2786 * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
2787

2795
2796 [base] Fix a dereference of uninitialized variable in PIC mode.
2797
2798 * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
2799 set before derefering to obtain `library'. The initialization
2800 of `clazz', `glyph', `library' and NULL pointer check are
2801 reordered to minimize PIC conditonals.
2802
2803 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2804
2805 [base] Insert explicit cast for GCC 4.6 in PIC mode.
2806
2807 * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
2808 configuration, FT_DEFAULT_MODULES_GET returns
2809 FT_Module_Class** pointer, GCC 4.6 warns that
2810 const FT_Module_Class* const* variable is warned as
2811 inappropriate to store it. To calm it, explicit cast is
2812 inserted. Also `library' is checked to prevent the NULL
2813 pointer dereference in FT_DEFAULT_MODULES_GET.

2817 Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
2818
2819 Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
2820 take no arguments but derefer the variable named `library'
2821 internally.
2822
2823 * src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
2824 set it if non-NULL driver is passed.

2850
2851 2012-01-02 Werner Lemberg <wl@gnu.org>
2852
2853 Fix tracing message for `loca' table.
2854
2855 * src/truetype/ttpload.c (tt_face_get_location): Don't emit a
2856 warning message if the last `loca' entry references an empty glyph.
2857
2858 2011-12-10 Werner Lemberg <wl@gnu.org>
2859
2860 Add some variable initializations.
2861 Reported by Richard COOK <rscook@unicode.org>.
2862
2863 * src/type1/t1driver.c (t1_ps_get_font_value): Initialize `val'.
2864 * src/smooth/ftgrays.c (gray_render_conic): Initialize `levels'
2865 earlier.
2866
2867 2011-12-08 Werner Lemberg <wl@gnu.org>
2868
2869 Fix serious scaling bug in `FT_Get_Advances'.
2870
2871 * src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by
2872 `FT_Load_Glyph' must be simply multiplied by 1024.
2873
2874 2011-12-08 Werner Lemberg <wl@gnu.org>
2875
2876 * src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing.

2879
2880 [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
2881
2882 Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
2883 was a configurable macro to disable Carbon-dependent code. Because
2884 now configure script sets DARWIN_NO_CARBON by default and disables
2885 Darwin & Carbon-dependent codes, these macros can be unified.
2886 FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
2887 (defined by default) is removed, because DARWIN_NO_CARBON violates
2888 FT_XXX naming convention of public macros, and a macro configured by
2889 default is not portable for the building without configure (e.g.
2890 make devel).
2891
2892 * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
2893 old Mac font support is requested and Carbon is available.
2894 * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
2895 for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is
2896 requested.
2897 * include/freetype/config/ftconfig.in: Ditto.
2898 * builds/vms/ftconfig.h: Ditto.
2899
2900 * src/base/ftbase.h: Remove DARWIN_NO_CARBON.
2901 * src/base/ftbase.c: Ditto.
2902 * src/base/ftobjs.c: Ditto.
2903 * src/base/ftrfork.c: Ditto.
2904
2905 * src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
2906 (same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
2907 * builds/mac/ftmac.c: Ditto.
2908
2909 * builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
2910 * builds/mac/FreeType.m68k_far.make.txt: Ditto.
2911 * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
2912 * builds/mac/FreeType.ppc_carbon.make.txt: Ditto.

2915
2916 Fix Savannah bug #34728 (`make devel' on Mac OS X).
2917
2918 * builds/toplevel.mk: Check `/dev/null' to identify the Unix-
2919 like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4).
2920 * builds/unix/detect.mk: Ditto.
2921

2923
2924 [apinames] Fix the overflow of signed integer hash.
2925
2926 * src/tools/apinames.c (names_add): Change the type of `h' from
2927 int to unsigned int, to prevent undefined behaviour in the
2928 overflow of signed integers (overflow of unsigned int is defined
2929 to be wrap around). Found by clang test suggested by Sean
2930 McBride.
2931
2932 2011-11-30 Werner Lemberg <wl@gnu.org>
2933
2934 [winfonts] Remove casts.

2945 update affected functions.
2946
2947 * src/type42/t42objs.c, src/type42/t42objs.h: Updated for t42driver
2948 changes.
2949
2950 2011-11-30 Werner Lemberg <wl@gnu.org>
2951
2952 [type1] Remove casts.

2958 Updated for t1driver changes.
2959 src/type1/t1objs.h (T1_Driver): Remove unused typedef.
2960 Updated for t1driver changes.
2961
2962 2011-11-27 Werner Lemberg <wl@gnu.org>
2963
2964 [bdf] Fix Savannah bug #34896.
2965
2966 ENCODING now covers the whole Unicode range.
2967
2968 Note, however, that this change is quite expensive since it
2969 increases the size of three arrays by almost 400kByte in total. The
2970 right fix is to replace the logic with something smarter.
2971 Additionally, there exist very old BDFs for three-byte CCCII
2972 encoding which exceeds the range of Unicode (another reason to have
2973 a smarter logic).
2974
2975 * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
2976 arrays.
2977 * src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.
2978
2979 2011-11-27 Werner Lemberg <wl@gnu.org>

2983 * src/bdf/bdflib.c (DBGMSG1, DBGMSG2): New macros.
2984 (_bdf_parse_glyphs): Use them.
2985
2986 2011-11-26 Werner Lemberg <wl@gnu.org>
2987
2988 Improve tracing.
2989
2990 * src/bdf/bdfdrivr.c (BDF_Face_Done), src/pcf/pcfdrivr.c
2991 (PCF_Face_Done): Remove tracing message.
2992
2993 * src/bdf/bdfdrivr.c (BDF_Face_Init), src/cff/cffobjs.c
2994 (cff_face_init), src/cid/cidobjs.c (cid_face_init),
2995 src/pfr/pfrobjs.c (pfr_face_init), src/sfnt/sfobjs.c
2996 (sfnt_init_face), src/truetype/ttobjs.c (tt_face_init),

3015
3016 2011-11-26 Werner Lemberg <wl@gnu.org>
3017
3018 Add new error code FT_Err_Missing_Module.
3019
3020 Previously, FreeType misleadingly returned
3021 FT_Err_Unknown_File_Format if a module was missing (or a test was
3022 missing completely).
3023
3024 * include/freetype/fterrdef.h (FT_Err_Missing_Module): Define.
3025
3026 * src/cff/cffobjs.c (cff_face_init), src/cff/cffdrivr.c
3027 (cff_get_glyph_name), src/cid/cidobjs.c (cid_face_init),
3028 src/sfnt/sfobjs.c (sfnt_init_face), src/truetype/ttobjs.c
3029 (tt_face_init), src/type1/t1objs.c (T1_Face_Init),
3030 src/type42/t42objs.c (T42_Face_Init, T42_Driver_Init): Updated.
3031
3032 * src/type1/t1afm.c (T1_Read_Metrics), src/type/t1objs.c
3033 (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Remove now
3034 redundant test for `psaux'.
3035
3036 2011-11-25 Werner Lemberg <wl@gnu.org>
3037
3038 [bdf] Add more error messages.
3039

3041 Add line number argument.
3042 Update all callers.
3043 (ERRMSG5, ERRMSG6, ERRMSG7, ERRMSG8, ERRMSG9): New macros.
3044 (_bdf_readstream, _bdf_set_default_spacing, _bdf_add_property,
3045 _bdf_parse_glyphs, _bdf_parse_start): Add error messages.
3046
3047 2011-11-24 Werner Lemberg <wl@gnu.org>
3048
3049 * include/freetype/fterrors.h: Remove dead code.

3264 [smooth] Slightly optimize conic and cubic flatterners.
3265
3266 * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move
3267 out some code from the main loop to speed it up.
3268
3269 2011-09-11 Tomas Hoger <thoger@redhat.com>
3270
3271 Slightly improve LZW_CLEAR handling.
3272
3273 * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
3274 Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
3275 handled as clear codes. This also re-sets old_code and old_char to
3276 predictable values, which is a little better than using `random'
3277 ones if the code following LZW_CLEAR is invalid.
3278
3279 2011-09-11 Tomas Hoger <thoger@redhat.com>
3280
3281 Add explicit LZW decompression stack size limit.
3282
3283 Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
3284 constructed correctly. It's even less than that, see e.g.
3285 libarchive code comment for a better size upper bound:
3286
3287 http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
3288
3289 This patch adds explicit stack size limit, enforced when stack is
3290 realloced.
3291
3292 An alternative is to ensure that code < state->prefix[code - 256]
3293 when traversing prefix table. Such check is less efficient and
3294 should not be required if prefix table is constructed correctly in
3295 the first place.
3296
3297 * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
3298
3299 2011-09-11 Tomas Hoger <thoger@redhat.com>
3300
3301 Protect against loops in the prefix table.
3302
3303 LZW decompressor did not sufficiently check codes read from the
3304 input LZW stream. A specially-crafted or corrupted input could
3305 create a loop in the prefix table, which leads to memory usage
3306 spikes, as there's no decompression stack size limit.
3307
3308 * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
3309 code in valid LZW stream must be 0..255.
3310 <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
3311 code > free_ent is invalid.

3527 [ftstroke] Major revision.
3528
3529 The main problems
3530 -----------------
3531
3532 o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
3533 joins (not bevel joins) were generated. Indeed, the meanings of
3534 `miter' and `bevel' were incorrectly reversed (consistently) in
3535 both the code and comments.
3536
3537 o The way bevel joins were constructed (whether specified
3538 explicitly, or created as a result of exceeding the miter limit)
3539 did not match what is required for stroked text in PostScript or
3540 PDF.
3541
3542 The main fixes
3543 --------------
3544
3545 o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
3546
3547 o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
3548 introduced to support PostScript and PDF miter joins.
3549
3550 o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
3551 alias for FT_STROKER_LINEJOIN_MITER.
3552
3553 Additionally, a variety of stroking errors have been fixed. These
3554 would cause various artifacts (including points `at infinity'),
3555 especially when stroking poor quality fonts.
3556
3557 See
3558
3559 http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
3560
3561 for example documents. The FreeType stroker now produces results
3562 very similar to that produced by GhostScript and Distiller for these
3563 fonts.
3564
3565 Other problems
3566 --------------
3567
3568 The following problems have been resolved:
3569
3570 o Inside corners could be generated incorrectly. Intersecting the
3571 inside corner could cause a missing triangular area and other
3572 effects.
3573
3574 The intersection point can only be used if the join is between
3575 two lines and both lines are long enough. The `optimization'
3576 condition in `ft_stroker_inside' has been corrected; this
3577 requires the line length to be passed into various functions and
3578 stored in `FT_StrokerRec'.
3579
3580 o Incorrect cubic curves could be generated. The angle
3581 calculations in `FT_Stroker_CubicTo' have been corrected to
3582 handle the case of the curve crossing the +/-PI direction.
3583
3584 o If the border radius was greater than the radius of curvature of
3585 a curve, then the negative sector would end up outside (not
3586 inside) the border. This situation is now recognized and the
3587 negative sector is circumnavigated in the opposite direction.
3588 (If round line joins are being used, this code is disabled
3589 because the line join will always cover the negative sector.)
3590
3591 o When a curve is split, the arcs may not join smoothly (especially
3592 if the curve turns sharply back on itself). Changes in
3593 direction between adjacent arcs were not handled. A round
3594 corner is now added if the deviation from one arc to the next is
3595 greater than a suitable threshold.
3596
3597 o The current direction wasn't retained if a the outline contained
3598 a zero length lineto or a curve that was determined to be
3599 `basically a point'. This could cause a spurious join to be
3600 added.
3601
3602 o Cubics with close control points could be mishandled. All eight
3603 cases are now distinguished correctly.
3604
3605 Other improvements
3606 ------------------
3607
3608 o Borders for cubic curves could be too `flat'.
3609 FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
3610 this.
3611
3612 o The handling and use of movable points has been simplified a
3613 little.
3614
3615 o Various values are now computed only if the results are actually
3616 needed.
3617
3618 o The directions of the outer and inner borders have been swapped,
3619 as recommended by Graham Asher.

3747 [gxvalid] Cleanup.
3748
3749 Some invalid, overrunning, unrecommended non-zero values
3750 are cared in paranoid validation mode only. There are
3751 many lines looking like:
3752
3753 if ( valid->root->level >= FT_VALIDATE_PARANOID )
3754 FT_INVALID_xxx;
3755
3756 To simplify them, GXV_SET_ERR_IF_PARANOID( err ) is
3757 introduced for more paranoid validation in future.
3758
3759 * src/gxvalid/gxvcommn.h (IS_PARANOID_VALIDATION):
3760 New macro to assure valid->root->level is more or
3761 equal to FT_VALIDATE_PARANOID. (GXV_SET_ERR_IF_PARANOID):
3762 New macro to raise an error if in paranoid validation.
3763 * src/gxvalid/gxvcommn.c: Use GXV_SET_ERR_IF_PARANOID().

3950
3951 The native SDK on earliest Mac OS X (10.0-10.1) did not have

4001 [autofit] Add bluezones for CJK Ideographs.
4002
4003 To remove extremas of vertical strokes of CJK Ideographs at
4004 low resolution and make the top and bottom horizontal stems
4005 aligned, bluezones for CJK Ideographs are calculated from
4006 sample glyphs. At present, vertical bluezones (bluezones
4007 to align vertical stems) are disabled by default. For detail, see

4064
4065 * builds/unix/configure.raw: New option `--disable-mmap'

4074 the sfnt table checksum even if non-zero value is written in
4075 the TrueType font header. Some bad PDF generators write
4076 wrong values. For details see examples and benchmark tests
4077 of the latency by recalculation:

4084
4085 * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids):
4086 Add 8 checksum sets for NEC FA family. For the tricky fonts
4087 without some tables (e.g. NEC FA fonts lack cvt table),
4088 extra check is added to assure that a zero-length table in the

4105 2011-04-25 Kan-Ru Chen <kanru@kanru.info>
4106
4107 [truetype] Always check the checksum to identify tricky fonts.
4108
4109 Because some PDF generators mangle the family name badly,
4110 the trickyness check by the checksum should be invoked always.
4111 For sample PDF, see
4112 http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html
4113
4114 * src/truetype/ttobjs.c (tt_check_trickyness): Even when

4124 added.
4125
4126 2011-04-21 Behdad Esfahbod <behdad@behdad.org>
4127
4128 Always ignore global advance.
4129
4130 This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
4131 deprecated, and ignored. The new behavior is what every major user
4132 of FreeType has been requesting. Global advance is broken in many
4133 CJK fonts. Just ignoring it by default makes most sense.
4134
4135 * src/truetype/ttdriver.c (tt_get_advances),
4136 src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,

4144 [autofit] Blur CJK stems if too many to preserve their gaps.
4145
4146 When there are too many stems to preserve their gaps in the
4147 rasterization of CJK Ideographs at a low resolution, blur the
4148 stems instead of showing clumped stems. See
4149 http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html

4152
4153 * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
4154 the previous stem by `has_last_stem' and `last_stem_pos', and skip
4155 a stem if the current and previous stem are too near to preserve
4156 the gap.

4171 * src/autofit/*: s/AF_DEBUG/FT_DEBUG_AUTOFIT/.
4172 s/AF_LOG/FT_TRACE5/.
4173 Define FT_COMPONENT where necessary.

4175 2011-04-18 Werner Lemberg <wl@gnu.org>
4176
4177 Synchronize config files.
4178

4184 [psaux] Fix Savannah bug #33047.
4185
4186 Patch submitted by anonymous reporter.
4187
4188 * src/psaux/psobjs.c (ps_table_add): Use FT_PtrDist for pointer
4189 difference.
4190
4191 2011-04-11 Kan-Ru Chen <kanru@kanru.info>
4192
4193 Fix reading of signed integers from files on 64bit platforms.
4194
4195 Previously, signed integers were converted to unsigned integers, but
4196 this can fail because of sign extension. For example, 0xa344a1eb
4197 becomes 0xffffffffa344a1eb.
4198
4199 We now do the reverse which is always correct because the integer
4200 size is the same during the cast from unsigned to signed.
4201
4202 * include/freetype/internal/ftstream.h, src/base/ftstream.c
4203 (FT_Stream_Get*): Replace with...
4204 (FT_Stream_GetU*): Functions which read unsigned integers.
4205 Update all macros accordingly.

4242 More C++ compilation fixes.
4243
4244 * src/autofit/afhints.c (af_glyph_hints_dump_points,
4245 af_glyph_hints_dump_segments, af_glyph_hints_dump_edges)
4246 [__cplusplus]: Protect with `extern "C"'.
4247
4248 2011-03-18 Werner Lemberg <wl@gnu.org>
4249
4250 C++ compilation fixes.
4251
4252 * src/autofit/aflatin.c (af_latin_hints_apply), src/autofit/afcjk.c
4253 (af_cjk_hints_apply): Use cast for `dim'.
4254
4255 2011-03-17 Alexei Podtelezhnikov <apodtele@gmail.com>
4256
4257 A better fix for Savannah bug #32671.
4258
4259 * src/smooth/ftgrays.c (gray_render_conic): Clean up code and
4260 replace WHILE loop with a more natural DO-WHILE construct.
4261
4262 2011-03-16 Werner Lemberg <wl@gnu.org>.
4263
4264 * src/base/ftstroke.c (FT_StrokerRec): Remove unused `valid' field.
4265 Suggested by Graham Asher.
4266
4267 2011-03-09 Werner Lemberg <wl@gnu.org>
4268
4269 Make FT_Sfnt_Table_Info return the number of SFNT tables.
4270
4271 * src/sfnt/sfdriver.c (sfnt_table_info): Implement it.

4277 [cff] Fix Savannah bug #27988.
4278
4279 * src/cff/cffobjs.c (remove_style): New function.
4280 (cff_face_init): Use it to strip off the style part of the family
4281 name.
4282
4283 2011-03-07 Werner Lemberg <wl@gnu.org>
4284
4285 * docs/CHANGES: Updated.

4287 2011-03-07 Alexei Podtelezhnikov <apodtele@gmail.com>
4288
4289 Quick fix for Savannah bug #32671.
4290
4291 This isn't the optimal solution yet, but it restores the previous
4292 rendering quality (more or less).
4293
4294 * src/smooth/ftgrays.c (gray_render_conic): Do more splitting.
4295
4296 2011-03-06 Werner Lemberg <wl@gnu.org>
4297
4298 Fix autohinting fallback.

4301 ignoring CFF-based OTFs.
4302
4303 2011-02-27 Werner Lemberg <wl@gnu.org>
4304
4305 Add AF_CONFIG_OPTION_USE_WARPER to control the autofit warper.

4366 2011-02-13 Bradley Grainger <bgrainger@logos.com>
4367
4368 Add inline assembly version of FT_MulFix for MSVC.
4369
4370 * include/freetype/config/ftconfig.h: Ported the FT_MulFix_i386
4371 function from GNU inline assembly syntax (see #ifdef __GNUC__ block
4372 above) to MASM syntax for Microsoft Visual C++.

4390 [cff] Ignore unknown operators in charstrings.
4391 Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>.
4392
4393 * src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing
4394 message for unknown operators and continue instead of exiting with a
4395 syntax error.
4396
4397 2011-02-01 Werner Lemberg <wl@gnu.org>
4398
4399 [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also.
4400
4401 * src/truetype/ttgload.c (tt_loader_init): Handle
4402 `FT_LOAD_PEDANTIC'.
4403 * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
4404 tt_size_init_bytecode, tt_size_ready_bytecode): New argument to
4405 handle pedantic mode.

4416
4417 [truetype] Improve handling of invalid references.
4418
4419 * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
4420 error codes only if pedantic hinting is active. At the same time,
4421 try to provide sane values which hopefully allow useful
4422 continuation. Exception to this is CALL and LOOPCALL – due to
4423 possible stack corruption it is necessary to bail out.
4424
4425 2011-01-31 Werner Lemberg <wl@gnu.org>
4426
4427 [truetype] Improve handling of stack underflow.
4428
4429 * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP,

4445
4446 [truetype] Fix handling of MIRP instruction.
4447
4448 Thanks to Greg Hitchcock who explained the issue.
4449
4450 * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
4451 `>' since the description in the specification is incorrect.
4452 This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
4453 65 medium' at 15ppem.
4454
4455 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>

4457 Fix ARM assembly code in include/freetype/config/ftconfig.h.
4458
4459 * include/freetype/config/ftconfig.h (FT_MulFix_arm):
4460 Copy the maintained code from builds/unix/ftconfig.in.
4461 Old GNU binutils could not accept the reduced syntax
4462 `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
4463 `orr %0, %0, %2, lsl #16' is better. Reported by
4464 Johnson Y. Yan. The bug report by Qt developers is
4465 considered too.

4471 [raster] Make bbox handling the same as with Microsoft's rasterizer.
4472
4473 Right before B/W rasterizing, the bbox gets simply rounded to
4474 integers. This fixes, for example, glyph `three' in font `Helvetica
4475 Neue LT Com 65 Medium' at 11ppem.
4476
4477 Thanks to Greg Hitchcock who explained this behaviour.
4478
4479 * src/raster/ftrend1.c (ft_raster1_render): Implement it.

4481 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4482
4483 Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
4484
4485 * builds/unix/configure.raw: Consider recent gcc-standard
4486 flags to specify architecture in CFLAGS & LDFLAGS
4487 harmonization. Requested by Savannah bug #32114, to
4488 support multilib feature of BuildRoot SDK correctly.
4489
4490 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4491
4492 Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
4493
4494 * builds/unix/configure.raw: Some important options that
4495 included in CFLAGS but not in LDFLAGS are copied to
4496 LDFLAGS, but the last option in CFLAGS was not checked.
4497
4498 2011-01-13 Werner Lemberg <wl@gnu.org>

4500 [raster] Add undocumented drop-out rule to the other bbox side also.

4505 2011-01-13 Werner Lemberg <wl@gnu.org>
4506
4507 [raster] Reduce jitter value.
4508
4509 This catches a rendering problem with glyph `x' from Tahoma at
4510 10ppem. It seems that the increase of the precision in the change
4511 from 2009-06-11 makes a larger jitter value unnecessary.
4512
4513 * src/raster/ftraster.c (Set_High_Precision): Implement it.
4514
4515 2011-01-13 Werner Lemberg <wl@gnu.org>
4516
4517 [raster] Handle drop-outs at glyph borders according to Microsoft.
4518
4519 If a drop-out rule would switch on a pixel outside of the glyph's
4520 bounding box, use the right (or top) pixel instead. This is an
4521 undocumented feature, but some fonts like `Helvetica Neue LT Com 65
4522 Medium' heavily rely on it.
4523
4524 Thanks to Greg Hitchcock who explained this behaviour.
4525
4526 * src/raster/ftraster.c (Vertical_Sweep_Drop,
4527 Horizontal_Sweep_Drop): Implement it.

4531 [cache] Fix Savannah bug #31923, patch drafted by Harsha.
4532
4533 When a node comparator changes the cached nodes during the
4534 search of a node matching with queried properties, the
4535 pointers obtained before the function should be updated to
4536 prevent the dereference to freed or reallocated nodes.
4537 To minimize the rescan of the linked list, the update is
4538 executed when the comparator notifies the change of cached
4539 nodes. This change depends previous change:
4540 38b272ffbbdaae276d636aec4ef84af407d16181
4541
4542 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
4543 top node if the cached nodes are changed.
4544 * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
4545
4546 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4547
4548 [cache] Notice if a cache query induced the node list change.
4549
4550 Some node comparators (comparing the cache node contents and the
4551 properties specified by the query) can flush the cache node to
4552 prevent the cache inflation. The change may invalidate the pointers
4553 to the node obtained before the node comparison, so it should be
4554 noticed to the caller. The problem caused by the cache node
4555 changing is reported by Harsha, see Savannah bug #31923.
4556
4557 * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
4558 `FT_Bool* list_changed' to indicate the change of the cached nodes
4559 to the caller.
4560 (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
4561 `_list_changed'.
4562 (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
4563 and update it when `FTC_Manager_FlushN' flushes any nodes.
4564
4565 * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
4566 FTC_Node_CompareFunc type.
4567 (ftc_gnode_compare): Ditto.
4568
4569 * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
4570 TRUE/FALSE macros.
4571 (ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
4572 list_changed' to indicate the change of the cache nodes (anyway, it
4573 is always FALSE).
4574
4575 * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
4576 TRUE/FALSE macros.
4577 (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
4578 indicate the change of the cache nodes (anyway, it is always FALSE).
4579 (ftc_cmap_node_remove_faceid): Ditto.
4580
4581 * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
4582 `FTC_CACHE_TRYLOOP_END', because the result is not needed.
4583 (FTC_Cache_Lookup): Watch the change of the cache nodes by
4584 `list_changed'.
4585 (FTC_Cache_RemoveFaceID): Ditto.
4586
4587 * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
4588 TRUE/FALSE macros.
4589 (ftc_gnode_compare): New argument `FT_Bool* list_changed' to
4590 indicate the change of the cache nodes (anyway, it is always FALSE).
4591 (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
4592 passed to `ftc_gnode_compare'.
4593 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
4594
4595 * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
4596 list_changed' to indicate the change of the cache nodes, anyway. It
4597 is updated by `FTC_CACHE_TRYLOOP'.
4598 (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
4599 passed to `ftc_snode_compare'.
4600 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
4601
4602 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4603
4604 [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
4605
4606 * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
4607 argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
4608 prototype.
4609 * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
4610 `cache' is not used by its child `ftc_gnode_compare'.
4611
4612 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4613
4614 [cache] Deduplicate the code to get the top node by a hash.
4615
4616 There are several duplicated code fragments getting the top node
4617 from a cache by a given hash, like:
4618
4619 idx = hash & cache->mask;
4620 if ( idx < cache->p )
4621 idx = hash & ( cache->mask * 2 + 1 );
4622 pnode = cache->buckets + idx;
4623
4624 To remove duplication, a cpp-macro to do same work
4625 `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
4626 configuration, non-`ftc_get_top_node_for_hash' is also introduced.
4627
4628 * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
4629 and implement inlined version.
4630 (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
4631 * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
4632 version.

4638
4639 [cache] inline-specific functions are conditionalized.
4640
4641 * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
4642 inlined configuration. This function is a thin wrapper of
4643 `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
4644 `nodecmp' argument). Under non-inlined configuration,
4645 `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
4646 `FTC_Cache->clazz.node_compare'.
4647
4648 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
4649 * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
4650 `ftc_snode_compare'.
4651 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

4654
4655 [cache] Correct a type mismatch under non-inlined config.
4656
4657 * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
4658 takes the node via a pointer `FTC_Node*', differently from cpp-macro
4659 `FTC_CACHE_LOOKUP_CMP'.

4662
4663 Update Jamfile to include Bzip2 support.
4664
4665 * Jamfile: Include src/bzip2 to project.
4666 Comments for lzw, gzip, bzip2 are changed to clarify that
4667 they are for compressed PCF fonts, not others.
4668 (e.g. compressed BDF fonts are not supported yet)
4669
4670 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4671
4672 Update Symbian project files to include Bzip2 support.
4673
4674 Currently, it provides `FT_Stream_OpenBzip2' that returns
4675 unimplemented error always, to prevent unresolved symbol
4676 error for the applications designed for Unix systems.
4677

4682
4683 Update classic MacOS makefiles to include Bzip2 support.
4684
4685 Currently, it provides `FT_Stream_OpenBzip2' that returns
4686 unimplemented error always, to prevent unresolved symbol
4687 error for the applications designed for Unix systems.
4688
4689 * builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o.

4696 Update Amiga makefiles to include Bzip2 support.
4697
4698 Currently, it provides `FT_Stream_OpenBzip2' that returns
4699 unimplemented error always, to prevent unresolved symbol
4700 error for the applications designed for Unix systems.
4701
4702 * builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c.
4703 * builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c.

4712 * builds/unix/freetype2.in: Ditto.
4713
4714 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4715
4716 * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
4717
4718 SYSTEM_ZLIB is used to switch the builtin zlib source
4719 or system zlib source out of FreeType2. But ftbzip2
4720 module has no builtin bzip2 library and always requires
4721 system bzip2 library. Thus SYSTEM_BZ2LIB is always yes,
4722 it is not used.

4766
4767 Apply Savannah patch #7422.
4768
4769 If we encounter a space in a string then the sbit buffer is NULL,
4770 height and width are 0s. So the check in ftc_snode_compare will
4771 always pass for spaces (comparision with 255). Here the comments
4772 above the condition are proper but the implementation is not. When
4773 we create an snode I think it is the proper way to initialize the
4774 width to 255 and then put a check for being equal to 255 in snode
4775 compare function.
4776
4777 * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
4778 value 255.
4779 (ftc_snode_compare): Fix condition.
4780

4787
4788 2010-12-09 Werner Lemberg <wl@gnu.org>
4789
4790 [cff] Allow `hlineto' and `vlineto' without arguments.
4791
4792 We simply ignore such instructions. This is invalid, but it doesn't
4793 harm; and indeed, there exist such subsetted fonts in PDFs.
4794
4795 Reported by Albert Astals Cid <aacid@kde.org>.
4796
4797 * src/cff/cffgload.c (cff_decoder_parse_charstrings)
4798 [cff_op_hlineto]: Ignore instruction if there aren't any arguments
4799 on the stack.
4800
4801 2010-11-28 Werner Lemberg <wl@gnu.org>

4848 start_point, check_points, add_point, add_point1, close_contour
4849 macros.
4850 Remove add_contour macro.
4851 Return error code from t1_builder_start_point and
4852 t1_builder_check_points when there was one (instead of returning 0).

4857 Some Latin TrueType fonts are still expected to be unhinted.
4858 Fix Savannah bug #31645.
4859
4860 * src/truetype/ttobjs.c (tt_check_trickyness): Divided to...
4861 (tt_check_trickyness_family): this checking family name, and
4862 (tt_check_trickyness_sfnt_ids): this checking cvt/fpgm/prep.
4863 (tt_get_sfnt_checksum): Function to retrieve the sfnt checksum
4864 for specified subtable even if cleared by lazy PDF generators.
4865 (tt_synth_sfnt_checksum): Function to calculate the checksum.

4905 [UVS] Fix `find_variant_selector_charmap', Savannah bug #31545.
4906
4907 Since 2010-07-04, `find_variant_selector_charmap' returns
4908 the first cmap subtable always under rogue-compatible
4909 configuration, it causes NULL pointer dereference and
4910 make UVS-related functions crashed.
4911
4912 * src/base/ftobjs.c (Fix find_variant_selector_charmap):
4913 Returns UVS cmap correctly.

4916
4917 [ftsmooth] Improve rendering.
4918
4919 * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
4920 cubic deviations have been estimated _after_ UPSCALE, whereas
4921 conic ones have been evaluated _before_ UPSCALE, which produces
4922 inferior rendering results. Fix this.
4923 Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has
4924 been tested with demo images sent to the mailing list. See

4952
4953 Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'.
4954
4955 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert
4956 the type of `_idx' from FT_PtrDist (by previous change)
4957 to original FT_UFast, to match with FT_CacheRec.

4959 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
4960
4961 [cache] Change the hash types to FT_PtrDist.
4962
4963 On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
4964 variables are inappropriate to calculate hash values
4965 from the memory address (64-bit). The hash variables
4966 are extended from FT_ULong to FT_PtrDist and new
4967 hashing macro functions are introduced. The hash
4968 values on 16-bit memory platforms are changed, but
4969 ILP32 and LP64 are not changed. The hash value in
4970 the cache subsystem is not reverted to the memory
4971 address, so using signed type FT_PtrDist is safe.
4972
4973 * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
4974 function to replace `FTC_FACE_ID_HASH' for portability.
4975 * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
4976 `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.
4977 * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
4978
4979 * src/cache/ftccache.h (FTC_NodeRec): The type of the
4980 member `hash' is changed from FT_UInt32 to FT_PtrDist.
4981
4982 * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
4983 argument `hash' is changed from FT_UInt32 to FT_PtrDist.
4984 (FTC_Cache_NewNode): Ditto.
4985 * src/cache/ftccache.c (ftc_cache_add): Ditto.
4986 (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
4987 * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
4988 * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
4989
4990 * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
4991 of the internal variable `hash' is changed to FT_PtrDist
4992 from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
4993 (FTC_SBitCache_Lookup): Ditto.
4994 (FTC_SBitCache_LookupScaler): Ditto.
4995 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
4996 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
4997 Also the type of the internal variable `_idx' is changed to
4998 FT_PtrDist from FT_UFast for better pointer calculation.

5000 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5001
5002 [cache] Hide internal macros incompatible with LLP64.
5003
5004 `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and
5005 `FTC_IMAGE_TYPE_HASH' are enclosed by
5006 FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
5007 normal clients.
5008
5009 For the history of these macros, see the investigation:

5011
5012 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5013
5014 Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.
5015
5016 On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
5017 cannot cover the memory address (64-bit). `FT_MEM_VAL' is
5018 used for hashing only and not dereferred, so using signed
5019 type FT_PtrDist is safe.
5020
5021 * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
5022 return value from FT_ULong to FT_PtrDist.
5023 (ft_mem_table_resize): The type of hash is changed to
5024 FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
5025
5026 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5027
5028 Replace "%lx" for memory address by "%p", LLP64 platforms.
5029
5030 On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
5031 the memory address (64-bit). Also the casts from the pointer
5032 type to long int should be removed to preserve the address
5033 correctly.
5034
5035 * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
5036 (End_Profile) Ditto.
5037 * src/truetype/ttinterp.c (Init_Context): Ditto.

5050 [raccess] Skip unrequired resource access rules by Darwin VFS.
5051
5052 When a resource fork access rule by Darwin VFS could open the
5053 resource fork but no font is found in it, the rest of rules
5054 by Darwin VFS are skipped. It reduces the warnings of the
5055 deprecated resource fork access method by recent Darwin kernel.
5056 Fix MacPorts ticket #18859:
5057 http://trac.macports.org/ticket/18859
5058
5059 * src/base/ftobjs.c (load_face_in_embedded_rfork):
5060 When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
5061 means that the file is possible to be `fopen'-ed but zero-sized.
5062 Also there is a case that the resource fork is not zero-sized,
5063 but no supported font exists in it. If a rule by Darwin VFS
5064 falls into such cases, there is no need to try other Darwin VFS
5065 rules anymore. Such cases are marked by vfs_rfork_has_no_font.
5066 If it is TRUE, the Darwin VFS rules are skipped.

5068 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5069
5070 [raccess] Grouping resource access rules based on Darwin VFS.
5071
5072 MacOS X/Darwin kernel supports a few tricky methods to access
5073 a resource fork via ANSI C or POSIX interface. Current resource
5074 fork accessor tries all possible methods to support all kernels.
5075 But if a method could open a resource fork but no font is found,
5076 there is no need to try other methods older than tested method.
5077 To determine whether the rule index is for Darwin VFS, a local
5078 function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
5079 To use this function in ftobjs.c etc but it should be inlined,
5080 it is exposed by ftbase.h.
5081
5082 * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
5083 the rules to access the resource fork.
5084 (raccess_guess_rec): New structure to bind the rule function and
5085 rule enum type.
5086 (FT_Raccess_Guess): The list of the rule functions is replaced by
5087 (raccess_guess_table): This. This is exposed to be used by other
5088 intra module functions.
5089 (raccess_rule_by_darwin_vfs): A function to return a boolean
5090 if the rule specified by the rule index is based on Darwin VFS.

5093
5094 Prevent to open a FT_Stream for zero-sized file on non-Unix.
5095
5096 builds/unix/ftsystem.c prevents to open an useless stream from
5097 zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
5098 stream drivers for ANSI C, Amiga and VMS return useless streams.
5099 For cross-platform consistency, all stream drivers should act
5100 same.
5101
5102 * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
5103 file is zero, FT_Err_Cannot_Open_Stream is returned.
5104 * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
5105 * src/vms/ftsystem.c (FT_Stream_Open): Ditto.

5201 when we fill `post' names by NULL, instead of per-entry message.
5202
5203 2010-09-20 Graham Asher <graham.asher@btinternet.com>
5204 David Bevan <david.bevan@pb.com>
5205
5206 [smooth] Fix and improve spline flattening.
5207
5208 This fixes the flattening of cubic, S-shaped curves and speeds up
5209 the handling of both the conic and cubic arcs.
5210
5211 See the discussions on the freetype-devel mailing list in late
5212 August and September 2010 for details.
5213
5214 * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.
5215 (TWorker): Remove `conic_level' and `cubic_level' elements.

5220
5221 2010-09-19 Werner Lemberg <wl@gnu.org>
5222
5223 Minor fixes.
5224
5225 * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'
5226 is `FT_UShort'.
5227 (cff_index_access_element): Don't use additions in comparison.
5228 * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type
5229 `FT_Long'.
5230 Don't use additions in comparison.
5231 Improve tracing messages.
5232 (load_format_25, load_post_names): Make `post_limit' of type
5233 `FT_Long'.
5234
5235 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5236
5237 [cff] Truncate the element length at the end of the stream.
5238 See Savannah bug #30975.
5239
5240 * src/cff/cffload.c (cff_index_access_element): `off2', the offset
5241 to the next element is truncated at the end of the stream to prevent
5242 invalid I/O. As `off1', the offset to the requested element has
5243 been checked by `FT_STREAM_SEEK', `off2' should be checked
5244 similarly.
5245
5246 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5247
5248 [cff] Ignore CID > 0xFFFFU.
5249 See Savannah bug #30975.
5250
5251 * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
5252 greater than 0xFFFFU. CFF font spec does not mention maximum CID in
5253 the font, but PostScript and PDF spec define that maximum CID is
5254 0xFFFFU.
5255
5256 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5257
5258 [cff] Make trace message in` cff_charset_load' verbose.
5259 See Savannah bug #30975.
5260
5261 * src/cff/cffload.c (cff_charset_load): Report the original `nleft'
5262 and truncated `nleft'.
5263
5264 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5265
5266 [cff] Correct `max_cid' from CID array length to max CID.
5267 See Savannah bug #30975.
5268
5269 * src/cff/cffload.c (cff_charset_compute_cids): Don't increment
5270 max_cid after detecting max CID. The array CFF_Charset->cids is
5271 allocated by max_cid + 1.
5272 (cff_charset_cid_to_gindex): Permit CID is less than or equal to
5273 CFF_Charset->max_cid.
5274 * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is
5275 calculated as CFF_Charset->max_cid + 1.
5276
5277 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5278
5279 [truetype] Sanitize the broken offsets in `loca'.
5280 See Savannah bug #31040.
5281
5282 * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
5283 offset to the requested entry in `glyf' exceeds the end of the
5284 table, return offset=0, length=0. If `pos2', the offset to the next
5285 entry in `glyf' exceeds the end of the table, truncate the entry
5286 length at the end of `glyf' table.
5287
5288 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5289
5290 [sfnt] Prevent overrunning in `post' table parser.
5291 See Savannah bug #31040.
5292
5293 * src/sfnt/ttpost.c (load_post_names): Get the length of `post'
5294 table and pass the limit of `post' table to `load_format_20' and
5295 `load_format_25'.
5296 (load_format_20): Stop the parsing when we reached at the limit of
5297 `post' table. If more glyph names are required, they are filled by
5298 NULL names.
5299
5300 2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5301
5302 [truetype] Don't duplicate size->twilight structure to be freed.
5303 See Savannah bug #31040 for detail.
5304
5305 * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
5306 FT_GlyphZoneRec size->twilight to be freed. If duplicated,
5307 `FT_FREE' erases the duplicated pointers only and leave original
5308 pointers. They can cause the double-free crash when the burst
5309 errors occur in TrueType interpreter and `free_buffer_in_size' is
5310 invoked repeatedly.
5311
5312 2010-09-15 Werner Lemberg <wl@gnu.org>
5313
5314 Make bytecode debugging with FontForge work again.
5315
5316 * src/truetype/ttinterp.c (TT_RunIns): Don't call
5317 `free_buffer_in_size' in case of error if a debugger is active.
5318
5319 2010-09-14 Werner Lemberg <wl@gnu.org>
5320
5321 Improve tracing messages.
5322
5323 * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
5324 message.
5325 * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
5326 tracing message.
5327 * src/truetype/ttgload.c (tt_loader_init): Add tracing message.
5328 * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
5329 glyph doesn't fit into a small bitmap container.
5330
5331 2010-09-13 Werner Lemberg <wl@gnu.org>
5332
5333 Fix minor issues reported by <muktha.narayan@wipro.com>.
5334
5335 * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
5336 redundant conditional check.
5337 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
5338 * src/cff/cffload.c (cff_encoding_load): Remove conditional check
5339 which always evaluates to `true'.
5340 * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
5341 Ditto.
5342 * src/truetype/ttinterp.c (Ins_IUP): Ditto.
5343 * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
5344 value is already dereferenced.
5345 * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
5346
5347 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5348
5349 Ignore the environmental setting of LIBTOOL.
5350 Patch is suggested by Adrian Bunk, to prevent unexpected
5351 reflection of environmental LIBTOOL. See:
5352 http://savannah.nongnu.org/patch/?7290
5353
5354 * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
5355 $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
5356 by default.
5357 * configure: When configured for the building out of source tee,
5358 FT_LIBTOOL_DIR is set to $(OBJ_DIR).
5359
5360 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5361
5362 [truetype] Decrease the trace level catching the interpreter error.
5363
5364 * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
5365 showing the error when the interpreter returns with an error,
5366 from` FT_TRACE7' to `FT_TRACE1'.
5367
5368 2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5369
5370 [truetype] Prevent bytecode reuse after the interpretation error.
5371
5372 * src/truetype/ttinterp.c (free_buffer_in_size): New function to
5373 free the buffer allocated during the interpretation of this glyph.
5374 (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
5375 an error occurs in the bytecode interpretation. The interpretation
5376 of invalid bytecode may break the function definitions and referring
5377 them in later interpretation is danger. By unsetting these flags,
5378 `fpgm' and `prep' tables are executed again in next interpretation.
5379
5380 This fixes Savannah bug #30798, reported by Robert Święcki.
5381
5382 2010-08-29 Werner Lemberg <wl@gnu.org>
5383
5384 [ftraster] Pacify compiler.

5387 not used.
5388
5389 2010-08-29 Werner Lemberg <wl@gnu.org>
5390
5391 [cff] Allow SIDs >= 65000.
5392
5393 * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
5394 The threshold for SIDs is not applicable here. I misinterpreted the
5395 `SID values 65000 and above are available for implementation use'
5396 sentence in the CFF specification.
5397

5400 2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5401
5402 Force hinting when the font lacks its familyname.
5403
5404 In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
5405 stream may lack `name' table because they are not required. Hinting
5406 for nameless fonts is safer for PDFs including embedded Chinese
5407 fonts. Written by David Bevan, see:
5408
5409 http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html
5410 http://lists.freedesktop.org/archives/poppler/2010-August/006310.html
5411
5412 * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by
5413 nameless font is given, TRUE is returned to enable hinting.
5414
5415 2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
5416
5417 Register yet another tricky TrueType font.
5418
5419 * src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?',
5420 a Kaishu typeface paired with `HuaTianSongTi?' by Huatian
5421 Information Industry.

5471 * src/base/ftobjs.c (FT_Done_Library): Specify the order of font

5740
5741 * src/cff/cffgload.c (cff_decoder_parse_charstrings)

5754 undefined (thus the rogue client compatibility is not required).
5755
5756 * src/cff/cffobjs.c (cff_face_init): Abort the automatic
5757 selection or synthesis of Unicode cmap subtable when the charmap
5758 index exceeds FT_MAX_CHARMAP_CACHEABLE.
5759 * src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message

5766 FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
5767 (FT_Select_Charmap): When a charmap matching with requested
5768 encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
5769 earlier one.
5770 (FT_Set_Charmap): When a charmap matching with requested
5771 charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
5772 earlier one.
5773 (FT_Get_Charmap_Index): When a requested charmap is found
5774 after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
5775 index.

5806
5807 Additional fix for Savannah bug #30306.
5808
5809 * src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the
5810 POST fragment is 0, the segment is completely ignored. The declared
5811 length of the segment is not cared at all. According to Adobe
5812 Technical Note 5040, type 0 segment is a comment only and should not
5813 be loaded for the interpreter. Reported by Robert Święcki.
5814
5815 2010-07-01 Werner Lemberg <wl@gnu.org>

5833
5834 * src/smooth/ftgrays.c (gray_render_span): Use cast to `unsigned
5835 int' to avoid integer overflow.
5836
5837 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller
5838 threshold values for `width' and `height'. This is not directly
5839 related to the bug fix but makes sense anyway.
5840

5844
5845 * src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the
5846 length of fragment declared in the POST fragment header, and prevent
5847 an underflow in length calculation. Some fonts set the length to
5848 zero in spite of the existence of a following 16bit `type'.

6161 [psaux] Fix Savannah bug #29846.
6162
6163 Previously we discovered fonts which used `setcurrentpoint' to set
6164 the initial point of a contour to 0,0. This caused FreeType to
6165 raise an error, because the `setcurrentpoint' operator is only
6166 supposed to be used with the results from an OtherSubr subroutine.
6167
6168 This was fixed by simply ignoring the error and carrying on.
6169
6170 Now we have found a font which uses setcurrentpoint to actually
6171 establish a non-zero point for a contour during the course of a
6172 glyph program. FWIW, these files may be produced by an application
6173 called `Intaglio' on the Mac, when converting TrueType fonts to
6174 Type 1.
6175
6176 The fix allows the new invalid behaviour, the old invalid behaviour
6177 and real proper usage of the operator to work the same way as Adobe
6178 interpreters apparently do.
6179
6180 * src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make
6181 `setcurrentpoint' use the top two elements of the stack to establish
6182 unconditionally the current x and y coordinates.
6183
6184 Make the `flex' subroutine handling (OtherSubr 0) put the current
6185 x,y coordinates onto the stack, instead of two dummy uninitialised
6186 values.
