53 2012-03-03 Werner Lemberg <wl@gnu.org>
55 Fix Savannah bug #35660.
57 For some divisions, we use casts to 32bit entities. Always guard
58 against division by zero with these casts also.
60 * src/base/ftcalc.c (ft_div64by32): Remove redundant cast.
61 (FT_MulDiv, FT_MulDiv_No_Round): Add 32bit cast.
62 (FT_DivFix): Add 32bit cast (this omission triggered the bug).
64 2012-03-03 Werner Lemberg <wl@gnu.org>
66 [psaux] Fix handling of track kerning.
68 * src/psaux/afmparse.c (afm_parse_track_kern): Don't inverse sign
69 for `min_kern'. It is indeed quite common that track kerning
70 *increases* spacing for very small sizes.
72 2012-03-02 Werner Lemberg <wl@gnu.org>
74 [truetype] Fix Savannah bug #35689.
76 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Check first outline
77 point.
79 2012-03-01 Werner Lemberg <wl@gnu.org>
81 [bdf] Fix Savannah bug #35656.
83 * src/bdf/bdflib.c (_bdf_parse_glyphs) <_BDF_BITMAP>: Check validity
84 of nibble characters instead of accessing `a2i' array.
86 2012-03-01 Werner Lemberg <wl@gnu.org>
88 [winfonts] Fix Savannah bug #35659.
90 * src/winfonts/winfnt.c (FNT_Face_Init): Check number of glyphs.
92 2012-03-01 Werner Lemberg <wl@gnu.org>
94 [bdf] Fix Savannah bug #35658.
96 * src/bdf/bdflib.c (_bdf_list_split): Initialize `field' elements
97 properly.
99 2012-03-01 Werner Lemberg <wl@gnu.org>
101 [psaux] Fix Savannah bug #35657.
103 If in function `skip_spaces' the routine `skip_comment' comes to the
104 end of buffer, `cur' is still increased by one, so we need to check
105 for `p >= limit' and not `p == limit'.
107 * src/psaux/psconv.c (PS_Conv_Strtol, PS_Conv_ToFixed,
108 PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Fix boundary checking.
110 2012-03-01 Werner Lemberg <wl@gnu.org>
112 [truetype] Fix Savannah bug #35646.
114 * src/truetype/ttinterp.c (Ins_MIRP): Typo, present since ages. The
115 code is now in sync with the other operators (e.g. MSIRP) which
116 modify twilight points.
118 2012-03-01 Werner Lemberg <wl@gnu.org>
120 [bdf] Fix Savannah bug #35643.
122 * src/bdf/bdflib.c (_bdf_list_ensure): Bring code in sync with
123 comment before `_bdf_list_split', this is, really allocate at least
124 five `field' elements.
126 2012-03-01 Werner Lemberg <wl@gnu.org>
128 [bdf] Fix Savannah bug #35641.
130 * src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if
131 _BDF_ENCODING isn't set. We need this because access to the `glyph'
132 variable might be undefined otherwise.
134 2012-03-01 Werner Lemberg <wl@gnu.org>
136 [truetype] Fix Savannah bug #35640.
138 * src/truetype/ttinterp.c (SkipCode, TT_RunIns): Fix boundary check
139 for NPUSHB and NPUSHW instructions.
141 2012-02-29 Werner Lemberg <wl@gnu.org>
143 [truetype] Fix Savannah bug #35601.
145 * src/truetype/ttinterp.c (Ins_SHZ): Use number of points instead of
146 last point for loop.
147 Also remove redundant boundary check.
149 2012-02-29 Werner Lemberg <wl@gnu.org>
151 [truetype] Remove redundant check.
153 * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Remove redundant
154 second check for ordered contour start points.
156 2012-02-29 Werner Lemberg <wl@gnu.org>
158 [truetype] Make SHC instruction behave similar to MS rasterizer.
160 * src/truetype/ttinterp.c (Ins_SHC): Handle virtual contour in
161 twilight zone.
163 2012-02-29 Alexei Podtelezhnikov <apodtele@gmail.com>
165 Avoid modulo operators against a power-of-two denominator.
167 * src/afcjk.c (af_hint_normal_stem), src/base/ftoutln.c
168 (ft_contour_has), src/cff/cffgload.c (cff_decoder_parse_charstrings)
169 <cff_op_vvcurveto, cff_op_hhcurveto, cff_op_hvcurveto>,
170 src/gxvalid/gxvcommn.c (GXV_32BIT_ALIGNMENT_VALIDATE),
171 src/gxvalid/gxvfeat.c (gxv_feat_setting_validate): Replace `%' with
172 `&' operator.
174 2012-02-29 Werner Lemberg <wl@gnu.org>
176 [autofit] Don't synchronize digit widths for light rendering mode.
178 We don't hint horizontally in this mode.
180 * src/autofit/afloader.c (af_loader_load_g) <Hint_Metrics>:
181 Implement it.
183 2012-02-26 Alexei Podtelezhnikov <apodtele@gmail.com>

194 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use `FT_Pos'
195 instead of `FT_UInt' for some variables and update comparisons
196 accordingly. A detailed analysis can be found in the bug report.
198 2012-02-26 Alexei Podtelezhnikov <apodtele@gmail.com>
200 [type42] Minor code optimization.
202 * src/type42/t42parse.c (t42_parse_sfnts): Use bitmask instead of

337 2012-02-11 Werner Lemberg <wl@gnu.org>
339 [truetype] Fix Savannah bug #35466.

356 `extensions' field.
358 2012-02-11 Werner Lemberg <wl@gnu.org>
360 Clean up `generic' fields.

386 * src/gxvalid/gxvcommn.c (gxv_XStateTable_subtable_setup):
387 gxv_set_length_by_ulong_offset() must be called with 3, not 4,
388 the number of the subtables in the state tables; classTable,
389 stateArray, entryTable.
391 2012-01-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
393 [raccess] Modify for PIC build.
395 Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
396 http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html
398 Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
399 are renamed with `ft_' suffixes.
401 * src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
402 to `ft_raccess_rule_by_darwin_vfs()'.
403 * src/base/ftobjs.c: Ditto.
405 * src/base/ftrfork.c: Declarations of FT_RFork_Rule,
406 raccess_guess_rec, are moved to...
407 * include/freetype/internal/ftrfork.h: Here.
409 * include/freetype/internal/ftrfork.h:
410 FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
411 to replace raccess_guess_table[] in both of PIC and non-PIC
412 modes.
413 * src/base/ftrfork.c: raccess_guess_table[] array is rewritten
414 by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.
416 * src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
417 storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
418 the function pointer from `ft_raccess_guess_table' storage in
419 `BasePIC' structure.
420 * src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
421 FT_RACCESS_GUESS_TABLE_GET.
422 (raccess_get_rule_type_from_rule_index): Add `library' as the
423 first argument to the function, to retrieve the storage of
424 `ft_raccess_guess_table' from it. Also `raccess_guess_table'
425 is replaced by FT_RACCESS_GUESS_TABLE_GET.
426 (ft_raccess_rule_by_darwin_vfs): Ditto.
428 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
430 Remove trailing spaces.
432 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
434 Formatting PIC related sources.

447 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
449 [autofit] Fix the inclusion of `aflatin2.h' in PIC file.
451 * src/autofit/afpic.c: Include `aflatin2.h' when
452 FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
453 Unconditionally inclusion causes declared but unimplemented
454 warning by GCC 4.6.
456 2012-01-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
458 [cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
460 * src/cff/cffpic.c: The declarations of
461 FT_Init_Class_cff_cmap_encoding_class_rec() and
462 FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
463 They can be obtained by the inclusion of cffcmap.h.
464 cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
465 FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
467 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
469 Fix redundant declaration warning in PIC mode.
471 Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
472 designed to declare xxx_pic_{free,init} by themselves.
473 Because these macros are used at the end of the module
474 interface (e.g. ttdriver.c) and the wrapper source to build
475 a module as a single object (e.g. truetype.c) includes
476 the PIC file (e.g. ttpic.c) before the module interface,
477 these macros are expanded AFTER xxx_pic_{free,init} body
478 when the modules are built as single object.
479 The declaration after the implementation causes the redundant
480 declaration warnings, so the declarations are moved to module
481 PIC headers (e.g. ttpic.h). Separating to other header files
482 are needed for multi build.
484 * include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
485 Remove class_##_pic_free and class_##_pic_init declarations.
486 * include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
487 FT_DEFINE_MODULE): Ditto.
489 * src/base/basepic.h: Insert a comment and fix coding style.
490 * src/autofit/afpic.h: Declare autofit_module_class_pic_{free,
491 init}.
492 * src/cff/cffpic.h: Declare cff_driver_class_pic_{free,init}.
493 * src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
494 init}.
495 * src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
496 init}.
497 * src/raster/rastpic.h: Declare
498 ft_raster{1,5}_renderer_class_pic_{free,init}
499 * src/sfnt/sfntpic.h: Declare sfnt_module_class_pic_{free,init}.
500 * src/smooth/ftspic.h: Declare
501 ft_smooth_{,lcd_,lcdv_}renderer_class_pic_{free,init}.
502 * src/truetype/ttpic.h: Declare tt_driver_class_pic_{free,init}.
504 2012-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
506 Make pspic.c to include module error header to fix multi build.
508 * src/psnames/pspic.c: Include `psnamerr.h'.
510 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
512 [base] Fix a dereference of uninitialized variable in PIC mode.
514 * src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
515 set before derefering to obtain `library'. The initialization
516 of `clazz', `glyph', `library' and NULL pointer check are
517 reordered to minimize PIC conditonals.
519 2012-01-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
521 [base] Insert explicit cast for GCC 4.6 in PIC mode.
523 * src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
524 configuration, FT_DEFAULT_MODULES_GET returns
525 FT_Module_Class** pointer, GCC 4.6 warns that
526 const FT_Module_Class* const* variable is warned as
527 inappropriate to store it. To calm it, explicit cast is
528 inserted. Also `library' is checked to prevent the NULL
529 pointer dereference in FT_DEFAULT_MODULES_GET.
531 2012-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
533 Fix PIC build broken by d9145241fe378104ba4c12a42534549faacc92e6.
535 Under PIC configuration, FT_{CFF,PSCMAPS,SFNT,TT}_SERVICES_GET
536 take no arguments but derefer the variable named `library'

592 * src/bdf/bdflib.c (_bdf_parse_start): Drop redundant error tracing.
594 2011-12-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
596 [mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
598 Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
599 was a configurable macro to disable Carbon-dependent code. Because
600 now configure script sets DARWIN_NO_CARBON by default and disables
601 Darwin & Carbon-dependent codes, these macros can be unified.
602 FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
603 (defined by default) is removed, because DARWIN_NO_CARBON violates
604 FT_XXX naming convention of public macros, and a macro configured by
605 default is not portable for the building without configure (e.g.
606 make devel).
608 * builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
609 old Mac font support is requested and Carbon is available.
610 * builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
611 for Mac OS X without Carbon (e.g. Mac OS X 10.4 for ppc64) is
612 requested.
613 * include/freetype/config/ftconfig.in: Ditto.
614 * builds/vms/ftconfig.h: Ditto.
616 * src/base/ftbase.h: Remove DARWIN_NO_CARBON.
617 * src/base/ftbase.c: Ditto.
618 * src/base/ftobjs.c: Ditto.
619 * src/base/ftrfork.c: Ditto.
621 * src/base/ftmac.c: Compile the body if FT_MACINTOSH is defined
622 (same with TT_USE_BYTECODE_INTERPRETER in ttinterp.c).
623 * builds/mac/ftmac.c: Ditto.
625 * builds/mac/FreeType.m68k_cfm.make.txt: Define FT_MACINTOSH.
626 * builds/mac/FreeType.m68k_far.make.txt: Ditto.

630 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
632 Fix Savannah bug #34728 (`make devel' on Mac OS X).
634 * builds/toplevel.mk: Check `/dev/null' to identify the Unix-
635 like systems without `init' nor `hurd' (e.g. Mac OS X >= 10.4).
636 * builds/unix/detect.mk: Ditto.
638 2011-11-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
640 [apinames] Fix the overflow of signed integer hash.
642 * src/tools/apinames.c (names_add): Change the type of `h' from
643 int to unsigned int, to prevent undefined behaviour in the
644 overflow of signed integers (overflow of unsigned int is defined
645 to be wrap around). Found by clang test suggested by Sean
646 McBride.
648 2011-11-30 Werner Lemberg <wl@gnu.org>
650 [winfonts] Remove casts.

676 Updated for t1driver changes.
678 2011-11-27 Werner Lemberg <wl@gnu.org>
680 [bdf] Fix Savannah bug #34896.
682 ENCODING now covers the whole Unicode range.
684 Note, however, that this change is quite expensive since it
685 increases the size of three arrays by almost 400kByte in total. The
686 right fix is to replace the logic with something smarter.
687 Additionally, there exist very old BDFs for three-byte CCCII
688 encoding which exceeds the range of Unicode (another reason to have
689 a smarter logic).
691 * src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
692 arrays.
693 * src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.
695 2011-11-27 Werner Lemberg <wl@gnu.org>

732 2011-11-26 Werner Lemberg <wl@gnu.org>
734 Add new error code FT_Err_Missing_Module.
736 Previously, FreeType misleadingly returned

738 missing completely).
740 * include/freetype/fterrdef.h (FT_Err_Missing_Module): Define.
742 * src/cff/cffobjs.c (cff_face_init), src/cff/cffdrivr.c
743 (cff_get_glyph_name), src/cid/cidobjs.c (cid_face_init),

980 [smooth] Slightly optimize conic and cubic flatterners.
982 * src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move
983 out some code from the main loop to speed it up.
985 2011-09-11 Tomas Hoger <thoger@redhat.com>
987 Slightly improve LZW_CLEAR handling.
989 * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
990 Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
991 handled as clear codes. This also re-sets old_code and old_char to
992 predictable values, which is a little better than using `random'
993 ones if the code following LZW_CLEAR is invalid.
995 2011-09-11 Tomas Hoger <thoger@redhat.com>
997 Add explicit LZW decompression stack size limit.
999 Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
1000 constructed correctly. It's even less than that, see e.g.
1001 libarchive code comment for a better size upper bound:
1003 http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
1005 This patch adds explicit stack size limit, enforced when stack is
1006 realloced.
1008 An alternative is to ensure that code < state->prefix[code - 256]
1009 when traversing prefix table. Such check is less efficient and
1010 should not be required if prefix table is constructed correctly in
1011 the first place.
1013 * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
1015 2011-09-11 Tomas Hoger <thoger@redhat.com>
1017 Protect against loops in the prefix table.
1019 LZW decompressor did not sufficiently check codes read from the
1020 input LZW stream. A specially-crafted or corrupted input could
1021 create a loop in the prefix table, which leads to memory usage
1022 spikes, as there's no decompression stack size limit.
1024 * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
1025 code in valid LZW stream must be 0..255.
1026 <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
1027 code > free_ent is invalid.
1029 2011-09-09 Werner Lemberg <wl@gnu.org>
1031 Better tracing of metrics.

1243 [ftstroke] Major revision.
1245 The main problems
1246 -----------------
1248 o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
1249 joins (not bevel joins) were generated. Indeed, the meanings of
1250 `miter' and `bevel' were incorrectly reversed (consistently) in
1251 both the code and comments.
1253 o The way bevel joins were constructed (whether specified
1254 explicitly, or created as a result of exceeding the miter limit)
1255 did not match what is required for stroked text in PostScript or
1256 PDF.
1258 The main fixes
1259 --------------
1261 o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
1263 o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
1264 introduced to support PostScript and PDF miter joins.
1266 o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
1267 alias for FT_STROKER_LINEJOIN_MITER.
1269 Additionally, a variety of stroking errors have been fixed. These
1270 would cause various artifacts (including points `at infinity'),
1271 especially when stroking poor quality fonts.
1273 See
1275 http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
1277 for example documents. The FreeType stroker now produces results
1278 very similar to that produced by GhostScript and Distiller for these
1279 fonts.
1281 Other problems
1282 --------------
1284 The following problems have been resolved:
1286 o Inside corners could be generated incorrectly. Intersecting the
1287 inside corner could cause a missing triangular area and other
1288 effects.
1290 The intersection point can only be used if the join is between
1291 two lines and both lines are long enough. The `optimization'
1292 condition in `ft_stroker_inside' has been corrected; this
1293 requires the line length to be passed into various functions and
1294 stored in `FT_StrokerRec'.
1296 o Incorrect cubic curves could be generated. The angle
1297 calculations in `FT_Stroker_CubicTo' have been corrected to
1298 handle the case of the curve crossing the +/-PI direction.
1300 o If the border radius was greater than the radius of curvature of
1301 a curve, then the negative sector would end up outside (not
1302 inside) the border. This situation is now recognized and the
1303 negative sector is circumnavigated in the opposite direction.
1304 (If round line joins are being used, this code is disabled
1305 because the line join will always cover the negative sector.)
1307 o When a curve is split, the arcs may not join smoothly (especially
1308 if the curve turns sharply back on itself). Changes in
1309 direction between adjacent arcs were not handled. A round
1310 corner is now added if the deviation from one arc to the next is
1311 greater than a suitable threshold.
1313 o The current direction wasn't retained if a the outline contained
1314 a zero length lineto or a curve that was determined to be
1315 `basically a point'. This could cause a spurious join to be
1316 added.
1318 o Cubics with close control points could be mishandled. All eight
1319 cases are now distinguished correctly.
1321 Other improvements
1322 ------------------
1324 o Borders for cubic curves could be too `flat'.
1325 FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
1326 this.
1328 o The handling and use of movable points has been simplified a
1329 little.
1331 o Various values are now computed only if the results are actually
1332 needed.
1334 o The directions of the outer and inner borders have been swapped,
1335 as recommended by Graham Asher.

1463 [gxvalid] Cleanup.
1465 Some invalid, overrunning, unrecommended non-zero values
1466 are cared in paranoid validation mode only. There are
1467 many lines looking like:
1469 if ( valid->root->level >= FT_VALIDATE_PARANOID )
1470 FT_INVALID_xxx;

1606 variables; `beforeGrowLimit', `beforeShrinkGrowLimit',
1607 `afterGrowLimit', `afterShrinkGrowLimit', `growFlags',
1608 `shrinkFlags'. Additional check for non-zero values in
1609 unused storage `justClass' is added.
1610 (gxv_just_actSubrecord_type0_validate): Conditionalize
1611 unvalidated variable `order'. GID is checked by
1612 gxv_just_check_max_gid(). Additional check for upside-down
1613 relationship between `lowerLimit' and `upperLimit' is added.
1614 (gxv_just_actSubrecord_type1_validate): GID is checked by
1615 gxv_just_check_max_gid().
1616 (gxv_just_actSubrecord_type2_validate): Conditionalize
1617 unvalidated variable `substThreshhold'. GID is checked by
1618 gxv_just_check_max_gid().

1627 [gxvalid] Preparation to fix gcc4.6 compiler warnings.
1629 * src/gxvalid/gxvcommn.h (GXV_LOAD_TRACE_VARS): New macro to
1630 conditionalize the variable which is only used for trace messages.
1631 Automatically set by FT_DEBUG_LEVEL_TRACE.
1632 (GXV_LOAD_UNUSED_VARS): New macro to conditionalize the loading of
1633 unvalidated variables. Undefined by default to calm gcc4.6 warning.
1634 (GXV_ValidatorRec.{min_gid,max_gid}): New variables to hold defined
1635 GID ranges, for the comparison of GID ranges in different subtables.

1657 remove unused variables.
1658 * src/autofit/aflatin.c (af_latin_hints_compute_edges): Comment out
1659 `up_dir'.
1660 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use `height_org'
1661 and `width_org' conditionalized.
1663 2011-05-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1665 [mac] Conditionalize the inclusion of `AvailabilityMacros.h'.
1667 The native SDK on earliest Mac OS X (10.0-10.1) did not have
1668 `AvailabilityMacros.h'. To prevent the inclusion of missing
1669 header file, ECANCELED (introduced in 10.2) in POSIX header
1670 file <errno.h> is checked to detect the system version.
1672 * include/freetype/config/ftconfig.h: Conditionalize the
1673 inclusion of `AvailabilityMacros.h'.
1674 * builds/unix/ftconfig.in: Ditto.
1675 * builds/vms/ftconfig.h: Ditto.
1677 2011-05-27 Werner Lemberg <wl@gnu.org>
1679 [autofit] Improve tracing of hinting process.

1696 af_glyph_hints_get_segment_offset) [!FT_DEBUG_AUTOFIT]: Provide
1697 return value.
1698 * src/cff/cffgload.c (cff_slot_load): Add cast.
1699 * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids): Use proper
1700 loop variable type.
1702 2011-05-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1704 Automake component `builds/unix/install-sh' is removed.
1706 * builds/unix/install-sh: Removed. It is not needed to
1707 include repository, because autogen.sh installs it.
1708 * builds/unix/.gitignore: Register install-sh.
1710 2011-05-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1712 [autofit] Make trace message for CJK bluezone more verbose.
1714 2011-05-08 Just Fill Bugs <mozbugbox@yahoo.com.au>
1715 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1717 [autofit] Add bluezones for CJK Ideographs.
1719 To remove extremas of vertical strokes of CJK Ideographs at
1720 low resolution and make the top and bottom horizontal stems
1721 aligned, bluezones for CJK Ideographs are calculated from
1722 sample glyphs. At present, vertical bluezones (bluezones
1723 to align vertical stems) are disabled by default. For detail, see
1724 http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00070.html
1725 http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00092.html
1726 http://lists.gnu.org/archive/html/freetype-devel/2011-05/msg00001.html
1728 * include/freetype/internal/fttrace.h: New trace component `afcjk'.
1729 * src/autofit/afcjk.h (AF_CJK{Blue,Axis,Metric}Rec): Add CJK version
1730 for AF_Latin{Blue,Axis,Metric}Rec.
1731 (af_cjk_metrics_check_digits): Ditto, shared with Indic module.
1732 (af_cjk_metrics_init_widths): Ditto.
1733 (af_cjk_metrics_init): Take AF_CJKMetric instead of AF_LatinMetric.

1735 (af_cjk_hints_init): Ditto (declaration).
1736 (af_cjk_hints_apply): Ditto (declaration).

1745 af_latin_hints_compute_blue_edges.
1746 (af_cjk_metrics_init_blues): New function, CJK version of
1747 af_latin_metrics_init_blues.
1748 (af_cjk_hints_edges): Add code to align the edge stems to blue zones.
1750 * src/autofit/afindic.c (af_indic_metrics_init): Take AF_CJKMetric
1751 instead of AF_LatinMetric, and initialize as af_cjk_metrics_init.
1752 However bluezones are not initialized.
1753 (af_indic_metrics_scale): Take AF_CJKMetric instead of AF_LatinMetric.
1754 (af_indic_hints_init): Ditto.
1755 (af_indic_hints_apply): Ditto.
1757 * docs/CHANGES: Note about CJK bluezone support.
1759 2011-05-06 Werner Lemberg <wl@gnu.org>
1761 [autofit] Remove unused struct member.
1763 * src/autofit/aflatin.h (AF_LatinAxis): Remove `control_overshoot'.
1765 2011-05-04 Werner Lemberg <wl@gnu.org>
1767 * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Simplify.
1769 2011-05-01 Just Fill Bugs <mozbugbox@yahoo.com.au>
1770 Werner Lemberg <wl@gnu.org>
1772 [autofit] Add more debugging functions.
1774 * src/autofit/afhints.c (af_glyph_hints_get_num_segments,
1775 af_glyph_hints_get_segment_offset): New functions.
1777 2011-05-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1779 Add new option `--disable-mmap' to configure script.
1781 * builds/unix/configure.raw: New option `--disable-mmap'
1782 is added. It is for the developers to simulate the systems
1783 without mmap() (like 4.3BSD, minix etc) on POSIX systems.
1785 2011-04-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1787 [truetype] Always recalculate the sfnt table checksum.
1789 * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate
1790 the sfnt table checksum even if non-zero value is written in
1791 the TrueType font header. Some bad PDF generators write
1792 wrong values. For details see examples and benchmark tests
1793 of the latency by recalculation:
1794 http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00091.html

1797 2011-04-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1799 [truetype] Register a set of tricky fonts, NEC FA family.
1801 * src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids):
1802 Add 8 checksum sets for NEC FA family. For the tricky fonts
1803 without some tables (e.g. NEC FA fonts lack cvt table),
1804 extra check is added to assure that a zero-length table in the
1805 registry is not included in the font.
1807 2011-04-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1809 [truetype] Fix a bug in the sfnt table checksum getter.
1811 * src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the
1812 return value of face->goto_table() correctly.
1814 2011-04-28 Werner Lemberg <wl@gnu.org>
1816 [autofit] Improve tracing messages.
1818 * src/autofit/aflatin.c (af_latin_metrics_init_blues,
1819 af_latin_align_linked_edge, af_latin_hint_edges): Do it.
1821 2011-04-25 Kan-Ru Chen <kanru@kanru.info>
1823 [truetype] Always check the checksum to identify tricky fonts.
1825 Because some PDF generators mangle the family name badly,
1826 the trickyness check by the checksum should be invoked always.
1827 For sample PDF, see
1828 http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html
1830 * src/truetype/ttobjs.c (tt_check_trickyness): Even when
1831 tt_check_trickyness_family() finds no trickyness,
1832 tt_check_trickyness_sfnt_ids() is invoked.
1834 2011-04-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
1836 [autofit] Add more Indic scripts with hanging baseline.
1838 * src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu,
1839 Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are
1840 added.
1842 2011-04-21 Behdad Esfahbod <behdad@behdad.org>
1844 Always ignore global advance.
1846 This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
1847 deprecated, and ignored. The new behavior is what every major user
1848 of FreeType has been requesting. Global advance is broken in many
1849 CJK fonts. Just ignoring it by default makes most sense.
1851 * src/truetype/ttdriver.c (tt_get_advances),
1852 src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
1853 tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
1854 src/truetype/ttgload.h: Implement it.
1856 * docs/CHANGES: Updated.
1858 2011-04-21 rainy6144 <rainy6144@gmail.com>
1860 [autofit] Blur CJK stems if too many to preserve their gaps.
1862 When there are too many stems to preserve their gaps in the
1863 rasterization of CJK Ideographs at a low resolution, blur the
1864 stems instead of showing clumped stems. See
1865 http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html
1866 http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html
1867 for details.
1869 * src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
1870 the previous stem by `has_last_stem' and `last_stem_pos', and skip
1871 a stem if the current and previous stem are too near to preserve
1872 the gap.
1874 2011-04-18 Werner Lemberg <wl@gnu.org>
1876 Integrate autofitter debugging stuff.
1878 * devel/ftoption.h, include/freetype/config/ftoption.h
1879 (FT_DEBUG_AUTOFIT): New macro.
1881 * include/freetype/internal/fttrace.h: Add trace components for
1882 autofitter.
1884 * src/autofit/aftypes.h (AF_LOG): Removed.
1885 (_af_debug): Removed.
1887 * src/autofit/*: s/AF_DEBUG/FT_DEBUG_AUTOFIT/.
1888 s/AF_LOG/FT_TRACE5/.
1889 Define FT_COMPONENT where necessary.

1905 difference.
1907 2011-04-11 Kan-Ru Chen <kanru@kanru.info>
1909 Fix reading of signed integers from files on 64bit platforms.
1911 Previously, signed integers were converted to unsigned integers, but
1912 this can fail because of sign extension. For example, 0xa344a1eb
1913 becomes 0xffffffffa344a1eb.
1915 We now do the reverse which is always correct because the integer
1916 size is the same during the cast from unsigned to signed.
1918 * include/freetype/internal/ftstream.h, src/base/ftstream.c
1919 (FT_Stream_Get*): Replace with...
1920 (FT_Stream_GetU*): Functions which read unsigned integers.
1921 Update all macros accordingly.
1923 * src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.
1925 2011-04-07 Werner Lemberg <wl@gnu.org>

1937 column widths.
1939 2011-03-30 Werner Lemberg <wl@gnu.org>
1941 * src/autofit/aftypes.h (AF_OutlineRec): Removed, unused.
1943 2011-03-24 Werner Lemberg <wl@gnu.org>
1945 * src/cff/cfftypes.h (CFF_MAX_CID_FONTS): Increase to 256.
1946 This limit is given on p. 37 of Adobe Technical Note #5014.
1948 2011-03-23 Werner Lemberg <wl@gnu.org>
1950 * src/truetype/ttpload.c (tt_face_load_loca): Fix mismatch warning.
1952 2011-03-20 Werner Lemberg <wl@gnu.org>
1954 * src/sfnt/sfobjs.c (sfnt_open_font): Check number of TTC subfonts.
1956 2011-03-19 Werner Lemberg <wl@gnu.org>
1958 More C++ compilation fixes.
1960 * src/autofit/afhints.c (af_glyph_hints_dump_points,
1961 af_glyph_hints_dump_segments, af_glyph_hints_dump_edges)
1962 [__cplusplus]: Protect with `extern "C"'.
1964 2011-03-18 Werner Lemberg <wl@gnu.org>
1966 C++ compilation fixes.
1968 * src/autofit/aflatin.c (af_latin_hints_apply), src/autofit/afcjk.c
1969 (af_cjk_hints_apply): Use cast for `dim'.
1971 2011-03-17 Alexei Podtelezhnikov <apodtele@gmail.com>
1973 A better fix for Savannah bug #32671.
1975 * src/smooth/ftgrays.c (gray_render_conic): Clean up code and
1976 replace WHILE loop with a more natural DO-WHILE construct.
1978 2011-03-16 Werner Lemberg <wl@gnu.org>.
1980 * src/base/ftstroke.c (FT_StrokerRec): Remove unused `valid' field.
1981 Suggested by Graham Asher.
1983 2011-03-09 Werner Lemberg <wl@gnu.org>
1985 Make FT_Sfnt_Table_Info return the number of SFNT tables.
1987 * src/sfnt/sfdriver.c (sfnt_table_info): Implement it.
1988 * include/freetype/tttables.h: Update documentation.
1989 * docs/CHANGES: Updated.
1991 2011-03-07 Bram Tassyns <bramt@enfocus.be>
1993 Fix Savannah bug #27988.
1995 * src/cff/cffobjs.c (remove_style): New function.
1996 (cff_face_init): Use it to strip off the style part of the family
1997 name.
1999 2011-03-07 Werner Lemberg <wl@gnu.org>
2001 * docs/CHANGES: Updated.
2003 2011-03-07 Alexei Podtelezhnikov <apodtele@gmail.com>
2005 Quick fix for Savannah bug #32671.
2007 This isn't the optimal solution yet, but it restores the previous
2008 rendering quality (more or less).
2010 * src/smooth/ftgrays.c (gray_render_conic): Do more splitting.
2012 2011-03-06 Werner Lemberg <wl@gnu.org>
2014 Fix autohinting fallback.
2016 * src/base/ftobjs.c (FT_Load_Glyph): Assure that we only check TTFs,
2017 ignoring CFF-based OTFs.
2019 2011-02-27 Werner Lemberg <wl@gnu.org>
2021 Add AF_CONFIG_OPTION_USE_WARPER to control the autofit warper.
2023 * devel/ftoption.h, include/freetype/config/ftoption.h
2024 (AF_CONFIG_OPTION_USE_WARPER): New macro.
2025 * src/autofit/aftypes.h (AF_USE_WARPER): Remove.

2048 [autofit] Comment out unused code.
2050 * src/autofit/aflatin.c, src/autofit/aflatin2.c
2051 (af_latin_hints_compute_edges): Do it.
2053 2011-02-24 Werner Lemberg <wl@gnu.org>
2055 * src/autofit/afhints.h (AF_GlyphHints): Remove unused field.
2057 2011-02-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2059 [cache] Fix an off-by-one bug in `FTC_Manager_RemoveFaceID'.

2084 Add inline assembly version of FT_MulFix for MSVC.
2086 * include/freetype/config/ftconfig.h: Ported the FT_MulFix_i386
2087 function from GNU inline assembly syntax (see #ifdef __GNUC__ block
2088 above) to MASM syntax for Microsoft Visual C++.
2090 2011-02-13 Bradley Grainger <bgrainger@logos.com>

2110 message for unknown operators and continue instead of exiting with a
2111 syntax error.
2113 2011-02-01 Werner Lemberg <wl@gnu.org>
2115 [truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also.

2122 * src/truetype/ttobjs.h: Updated.
2124 2011-01-31 Werner Lemberg <wl@gnu.org>
2126 [truetype] Protect jump instructions against endless loops.
2128 * src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error
2129 if offset is zero.
2131 2011-01-31 Werner Lemberg <wl@gnu.org>
2133 [truetype] Improve handling of invalid references.
2135 * src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
2136 error codes only if pedantic hinting is active. At the same time,
2137 try to provide sane values which hopefully allow useful
2138 continuation. Exception to this is CALL and LOOPCALL – due to
2139 possible stack corruption it is necessary to bail out.
2141 2011-01-31 Werner Lemberg <wl@gnu.org>
2143 [truetype] Improve handling of stack underflow.
2145 * src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP,
2146 Ins_DELTAC): Exit with error only if `pedantic_hinting' is set.
2147 Otherwise, try to do something sane.
2149 2011-01-30 Werner Lemberg <wl@gnu.org>
2151 * src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message.
2153 2011-01-30 LIU Sun-Liang <sunliang_liu@foxitsoftware.com>
2155 [truetype]: Fix behaviour of MIAP for invalid arguments.
2157 * src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in
2158 case of error.
2160 2011-01-18 Werner Lemberg <wl@gnu.org>
2162 [truetype] Fix handling of MIRP instruction.
2164 Thanks to Greg Hitchcock who explained the issue.
2166 * src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
2167 `>' since the description in the specification is incorrect.
2168 This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
2169 65 medium' at 15ppem.
2171 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2173 Fix ARM assembly code in include/freetype/config/ftconfig.h.
2175 * include/freetype/config/ftconfig.h (FT_MulFix_arm):
2176 Copy the maintained code from builds/unix/ftconfig.in.
2177 Old GNU binutils could not accept the reduced syntax
2178 `orr %0, %2, lsl #16'. Un-omitted syntax like RVCT,
2179 `orr %0, %0, %2, lsl #16' is better. Reported by
2180 Johnson Y. Yan. The bug report by Qt developers is
2181 considered too.
2183 http://bugreports.qt.nokia.com/browse/QTBUG-6521
2185 2011-01-15 Werner Lemberg <wl@gnu.org>
2187 [raster] Make bbox handling the same as with Microsoft's rasterizer.
2189 Right before B/W rasterizing, the bbox gets simply rounded to
2190 integers. This fixes, for example, glyph `three' in font `Helvetica
2191 Neue LT Com 65 Medium' at 11ppem.
2193 Thanks to Greg Hitchcock who explained this behaviour.
2195 * src/raster/ftrend1.c (ft_raster1_render): Implement it.
2197 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2199 Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
2201 * builds/unix/configure.raw: Consider recent gcc-standard
2202 flags to specify architecture in CFLAGS & LDFLAGS
2203 harmonization. Requested by Savannah bug #32114, to
2204 support multilib feature of BuildRoot SDK correctly.
2206 2011-01-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2208 Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
2210 * builds/unix/configure.raw: Some important options that
2211 included in CFLAGS but not in LDFLAGS are copied to
2212 LDFLAGS, but the last option in CFLAGS was not checked.
2214 2011-01-13 Werner Lemberg <wl@gnu.org>
2216 [raster] Add undocumented drop-out rule to the other bbox side also.
2218 * src/raster/ftraster.c (Vertical_Sweep_Drop,
2219 Horizontal_Sweep_Drop): Implement it.
2221 2011-01-13 Werner Lemberg <wl@gnu.org>
2223 [raster] Reduce jitter value.
2225 This catches a rendering problem with glyph `x' from Tahoma at
2226 10ppem. It seems that the increase of the precision in the change
2227 from 2009-06-11 makes a larger jitter value unnecessary.
2229 * src/raster/ftraster.c (Set_High_Precision): Implement it.
2231 2011-01-13 Werner Lemberg <wl@gnu.org>
2233 [raster] Handle drop-outs at glyph borders according to Microsoft.
2235 If a drop-out rule would switch on a pixel outside of the glyph's
2236 bounding box, use the right (or top) pixel instead. This is an
2237 undocumented feature, but some fonts like `Helvetica Neue LT Com 65
2238 Medium' heavily rely on it.
2240 Thanks to Greg Hitchcock who explained this behaviour.
2242 * src/raster/ftraster.c (Vertical_Sweep_Drop,
2243 Horizontal_Sweep_Drop): Implement it.
2245 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2247 [cache] Fix Savannah bug #31923, patch drafted by Harsha.
2249 When a node comparator changes the cached nodes during the
2250 search of a node matching with queried properties, the
2251 pointers obtained before the function should be updated to
2252 prevent the dereference to freed or reallocated nodes.
2253 To minimize the rescan of the linked list, the update is
2254 executed when the comparator notifies the change of cached
2255 nodes. This change depends previous change:
2256 38b272ffbbdaae276d636aec4ef84af407d16181
2258 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
2259 top node if the cached nodes are changed.
2260 * src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
2262 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2264 [cache] Notice if a cache query induced the node list change.
2266 Some node comparators (comparing the cache node contents and the
2267 properties specified by the query) can flush the cache node to
2268 prevent the cache inflation. The change may invalidate the pointers
2269 to the node obtained before the node comparison, so it should be
2270 noticed to the caller. The problem caused by the cache node
2271 changing is reported by Harsha, see Savannah bug #31923.
2273 * src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
2274 `FT_Bool* list_changed' to indicate the change of the cached nodes
2275 to the caller.
2276 (FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
2277 `_list_changed'.
2278 (FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
2279 and update it when `FTC_Manager_FlushN' flushes any nodes.
2281 * src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
2282 FTC_Node_CompareFunc type.
2283 (ftc_gnode_compare): Ditto.
2285 * src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
2286 TRUE/FALSE macros.
2287 (ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
2288 list_changed' to indicate the change of the cache nodes (anyway, it
2289 is always FALSE).
2291 * src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
2292 TRUE/FALSE macros.
2293 (ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
2294 indicate the change of the cache nodes (anyway, it is always FALSE).
2295 (ftc_cmap_node_remove_faceid): Ditto.
2297 * src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
2298 `FTC_CACHE_TRYLOOP_END', because the result is not needed.
2299 (FTC_Cache_Lookup): Watch the change of the cache nodes by
2300 `list_changed'.
2301 (FTC_Cache_RemoveFaceID): Ditto.
2303 * src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
2304 TRUE/FALSE macros.
2305 (ftc_gnode_compare): New argument `FT_Bool* list_changed' to
2306 indicate the change of the cache nodes (anyway, it is always FALSE).
2307 (FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
2308 passed to `ftc_gnode_compare'.
2309 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
2311 * src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
2312 list_changed' to indicate the change of the cache nodes, anyway. It
2313 is updated by `FTC_CACHE_TRYLOOP'.
2314 (FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
2315 passed to `ftc_snode_compare'.
2316 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
2318 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2320 [cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
2322 * src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
2323 argument `FTC_Cache cache' to fit FTC_Node_CompareFunc
2324 prototype.
2325 * src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
2326 `cache' is not used by its child `ftc_gnode_compare'.
2328 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2330 [cache] Deduplicate the code to get the top node by a hash.
2332 There are several duplicated code fragments getting the top node
2333 from a cache by a given hash, like:
2335 idx = hash & cache->mask;
2336 if ( idx < cache->p )
2337 idx = hash & ( cache->mask * 2 + 1 );
2338 pnode = cache->buckets + idx;
2340 To remove duplication, a cpp-macro to do same work
2341 `FTC_NODE__TOP_FOR_HASH' is introduced. For non-inlined
2342 configuration, non-`ftc_get_top_node_for_hash' is also introduced.
2344 * src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
2345 and implement inlined version.
2346 (FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
2347 * src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
2348 version.
2349 (ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
2350 (ftc_node_hash_link): Ditto.
2351 (FTC_Cache_Lookup): Ditto.
2353 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2355 [cache] inline-specific functions are conditionalized.
2357 * src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
2358 inlined configuration. This function is a thin wrapper of
2359 `ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
2360 `nodecmp' argument). Under non-inlined configuration,
2361 `ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
2362 `FTC_Cache->clazz.node_compare'.
2364 * src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
2365 * src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
2366 `ftc_snode_compare'.
2367 * src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
2369 2011-01-09 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2371 [cache] Correct a type mismatch under non-inlined config.
2373 * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
2374 takes the node via a pointer `FTC_Node*', differently from cpp-macro
2375 `FTC_CACHE_LOOKUP_CMP'.
2377 2011-01-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2379 Update Jamfile to include Bzip2 support.
2381 * Jamfile: Include src/bzip2 to project.
2382 Comments for lzw, gzip, bzip2 are changed to clarify that
2383 they are for compressed PCF fonts, not others.
2384 (e.g. compressed BDF fonts are not supported yet)
2386 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2388 Update Symbian project files to include Bzip2 support.
2390 Currently, it provides `FT_Stream_OpenBzip2' that returns
2391 unimplemented error always, to prevent unresolved symbol
2392 error for the applications designed for Unix systems.
2394 * builds/symbian/bld.inf: Include ftbzip2.h.
2395 * builds/symbian/freetype.mmp: Include ftbzip2.c.
2397 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2399 Update classic MacOS makefiles to include Bzip2 support.
2401 Currently, it provides `FT_Stream_OpenBzip2' that returns
2402 unimplemented error always, to prevent unresolved symbol
2403 error for the applications designed for Unix systems.
2405 * builds/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o.
2406 * builds/mac/FreeType.m68k_far.make.txt: Ditto.
2407 * builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x.
2408 * builds/mac/FreeType.ppc_classic.make.txt: Ditto.
2410 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2412 Update Amiga makefiles to include Bzip2 support.
2414 Currently, it provides `FT_Stream_OpenBzip2' that returns
2415 unimplemented error always, to prevent unresolved symbol
2416 error for the applications designed for Unix systems.
2418 * builds/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c.
2419 * builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c.
2420 * builds/amiga/smakefile: Ditto.
2422 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2424 Update pkg-config tools to reflect Bzip2 support.
2426 * builds/unix/freetype-config.in: Include `-lbz2' to
2427 --libs output, if built with Bzip2 support.
2428 * builds/unix/freetype2.in: Ditto.
2430 2011-01-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2432 * builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
2434 SYSTEM_ZLIB is used to switch the builtin zlib source
2435 or system zlib source out of FreeType2. But ftbzip2
2436 module has no builtin bzip2 library and always requires
2437 system bzip2 library. Thus SYSTEM_BZ2LIB is always yes,
2438 it is not used.
2440 2011-01-03 Werner Lemberg <wl@gnu.org>
2442 */rules.mk: Handle `*pic.c' files.
2444 2010-12-31 Werner Lemberg <wl@gnu.org>
2446 * src/cff/cfftypes.h (CFF_MAX_CID_FONTS): Increase to 64.
2447 Problem reported by Tom Bishop <wenlin@wenlin.com>.
2449 2010-12-31 Werner Lemberg <wl@gnu.org>
2451 Improve bzip2 support.
2453 * include/freetype/ftmoderr.h: Add bzip2.

2467 (FT_CONFIG_OPTION_USE_BZIP2): Define.
2468 * include/freetype/config/ftheader.h (FT_BZIP2_H): Define.
2470 * include/freetype/ftbzip2.h: New file.
2472 * src/bzip2/*: New files.

2475 * src/pcf/pcfdrvr.c: Include FT_BZIP2_H.
2476 s/gzip_/comp_/.
2477 (PCF_Face_Init): Handle bzip2 compressed files.
2479 * docs/formats.txt, modules.cfg: Updated.
2481 2010-12-25 Harsha <mm.harsha@gmail.com>
2483 Apply Savannah patch #7422.
2485 If we encounter a space in a string then the sbit buffer is NULL,
2486 height and width are 0s. So the check in ftc_snode_compare will
2487 always pass for spaces (comparision with 255). Here the comments
2488 above the condition are proper but the implementation is not. When
2489 we create an snode I think it is the proper way to initialize the
2490 width to 255 and then put a check for being equal to 255 in snode
2491 compare function.
2493 * src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
2494 value 255.
2495 (ftc_snode_compare): Fix condition.
2497 2010-12-13 Werner Lemberg <wl@gnu.org>
2499 Fix parameter handling of `FT_Set_Renderer'.
2500 Reported by Kirill Tishin <siege@bk.ru>.
2502 * src/base/ftobjs.c (FT_Set_Renderer): Increment `parameters'.
2504 2010-12-09 Werner Lemberg <wl@gnu.org>
2506 [cff] Allow `hlineto' and `vlineto' without arguments.
2508 We simply ignore such instructions. This is invalid, but it doesn't
2509 harm; and indeed, there exist such subsetted fonts in PDFs.
2511 Reported by Albert Astals Cid <aacid@kde.org>.
2513 * src/cff/cffgload.c (cff_decoder_parse_charstrings)
2514 [cff_op_hlineto]: Ignore instruction if there aren't any arguments
2515 on the stack.
2517 2010-11-28 Werner Lemberg <wl@gnu.org>
2519 * Version 2.4.4 released.

2547 2010-11-28 Alexei Podtelezhnikov <apodtele@gmail.com>
2549 [ftsmooth]: Minor code simplification.
2551 * src/smooth/ftgrays (gray_render_cubic): Do only one comparison
2552 instead of two.
2554 2010-11-26 Johnson Y. Yan <yinsen_yan@foxitsoftware.com>
2556 [truetype] Better multi-threading support.
2558 * src/truetype/ttinterp.c (TT_Load_Context): Reset glyph zone
2559 references.
2561 2010-11-23 John Tytgat <John.Tytgat@esko.com>
2563 * src/psaux/t1decode.c (t1_decoder_parse_charstring): Expand
2564 start_point, check_points, add_point, add_point1, close_contour
2565 macros.
2566 Remove add_contour macro.
2567 Return error code from t1_builder_start_point and
2568 t1_builder_check_points when there was one (instead of returning 0).
2570 2010-11-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2572 [truetype] Identify the tricky fonts by cvt/fpgm/prep checksums.
2573 Some Latin TrueType fonts are still expected to be unhinted.
2574 Fix Savannah bug #31645.
2576 * src/truetype/ttobjs.c (tt_check_trickyness): Divided to...
2577 (tt_check_trickyness_family): this checking family name, and
2578 (tt_check_trickyness_sfnt_ids): this checking cvt/fpgm/prep.
2579 (tt_get_sfnt_checksum): Function to retrieve the sfnt checksum
2580 for specified subtable even if cleared by lazy PDF generators.
2581 (tt_synth_sfnt_checksum): Function to calculate the checksum.
2583 2010-11-18 Werner Lemberg <wl@gnu.org>
2585 [truetype] Fix `loca' handling for inconsistent number of glyphs.
2586 Reported by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>.
2588 * src/truetype/ttpload.c (tt_face_load_loca): While sanitizing,
2589 handle case where `loca' is the last table in the font.
2591 2010-11-18 Werner Lemberg <wl@gnu.org>
2593 [sfnt] Ignore all errors while loading `OS/2' table.
2594 Suggested by Johnson Y. Yan <yinsen_yan@foxitsoftware.com>.
2596 * src/sfnt/sfobjs.c (sfnt_load_face): Do it.
2598 2010-11-18 Johnson Y. Yan <yinsen_yan@foxitsoftware.com>
2600 [type1] Fix matrix normalization.
2602 * src/type1/t1load.c (parse_font_matrix): Handle sign of scaling
2603 factor.
2605 2010-11-18 Werner Lemberg <wl@gnu.org>
2607 [type1] Improve guard against malformed data.
2608 Based on a patch submitted by Johnson Y. Yan
2609 <yinsen_yan@foxitsoftware.com>
2611 * src/type1/t1load.c (read_binary_data): Check `size'.
2613 2010-11-17 Werner Lemberg <wl@gnu.org>
2615 [sfnt] While tracing, output table checksums also.
2617 * src/sfnt/ttload.c (tt_face_load_font_dir): Do it.
2619 2010-11-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2621 [UVS] Fix `find_variant_selector_charmap', Savannah bug #31545.
2623 Since 2010-07-04, `find_variant_selector_charmap' returns
2624 the first cmap subtable always under rogue-compatible
2625 configuration, it causes NULL pointer dereference and
2626 make UVS-related functions crashed.
2628 * src/base/ftobjs.c (Fix find_variant_selector_charmap):
2629 Returns UVS cmap correctly.
2631 2010-11-01 Alexei Podtelezhnikov <apodtele@gmail.com>
2633 [ftsmooth] Improve rendering.
2635 * src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
2636 cubic deviations have been estimated _after_ UPSCALE, whereas
2637 conic ones have been evaluated _before_ UPSCALE, which produces
2638 inferior rendering results. Fix this.
2639 Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has
2640 been tested with demo images sent to the mailing list. See

2648 [ftraster] Minor fixes.
2650 Reported by Tom Bishop <wenlin@wenlin.com>.
2652 * src/raster/ftraster.c (ULong): Remove unused typedef.
2653 (TWorker): Remove unused variable `precision_mask'.
2655 2010-10-28 Werner Lemberg <wl@gnu.org>
2657 [ftraster] Fix rendering.
2659 Problem reported by Tom Bishop <wenlin@wenlin.com>; see
2660 thread starting with
2662 http://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html
2664 * src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv
2665 since the involved multiplication exceeds 32 bits.
2667 2010-10-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2669 Revert a change of `_idx' type in `FTC_CACHE_LOOKUP_CMP'.
2671 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert
2672 the type of `_idx' from FT_PtrDist (by previous change)
2673 to original FT_UFast, to match with FT_CacheRec.
2675 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2677 [cache] Change the hash types to FT_PtrDist.
2679 On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
2680 variables are inappropriate to calculate hash values
2681 from the memory address (64-bit). The hash variables
2682 are extended from FT_ULong to FT_PtrDist and new
2683 hashing macro functions are introduced. The hash
2684 values on 16-bit memory platforms are changed, but
2685 ILP32 and LP64 are not changed. The hash value in
2686 the cache subsystem is not reverted to the memory
2687 address, so using signed type FT_PtrDist is safe.
2689 * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
2690 function to replace `FTC_FACE_ID_HASH' for portability.
2691 * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
2692 `FTC_FACE_ID_HASH' by `_FTC_FACE_ID_HASH'.
2693 * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
2695 * src/cache/ftccache.h (FTC_NodeRec): The type of the
2696 member `hash' is changed from FT_UInt32 to FT_PtrDist.
2698 * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
2699 argument `hash' is changed from FT_UInt32 to FT_PtrDist.
2700 (FTC_Cache_NewNode): Ditto.
2701 * src/cache/ftccache.c (ftc_cache_add): Ditto.
2702 (FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
2703 * src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
2704 * src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
2706 * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
2707 of the internal variable `hash' is changed to FT_PtrDist
2708 from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
2709 (FTC_SBitCache_Lookup): Ditto.
2710 (FTC_SBitCache_LookupScaler): Ditto.
2711 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
2712 * src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
2713 Also the type of the internal variable `_idx' is changed to
2714 FT_PtrDist from FT_UFast for better pointer calculation.
2716 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2718 [cache] Hide internal macros incompatible with LLP64.
2720 `FT_POINTER_TO_ULONG', `FTC_FACE_ID_HASH', and
2721 `FTC_IMAGE_TYPE_HASH' are enclosed by
2722 FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
2723 normal clients.
2725 For the history of these macros, see the investigation:
2726 http://lists.gnu.org/archive/html/freetype/2010-10/msg00022.html
2728 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2730 Change the type of `FT_MEM_VAL' from FT_ULong to FT_PtrDist.
2732 On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
2733 cannot cover the memory address (64-bit). `FT_MEM_VAL' is
2734 used for hashing only and not dereferred, so using signed
2735 type FT_PtrDist is safe.
2737 * src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
2738 return value from FT_ULong to FT_PtrDist.
2739 (ft_mem_table_resize): The type of hash is changed to
2740 FT_PtrDist. (ft_mem_table_get_nodep): Ditto.
2742 2010-10-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2744 Replace "%lx" for memory address by "%p", LLP64 platforms.
2746 On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
2747 the memory address (64-bit). Also the casts from the pointer
2748 type to long int should be removed to preserve the address
2749 correctly.
2751 * src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
2752 (End_Profile) Ditto.
2753 * src/truetype/ttinterp.c (Init_Context): Ditto.
2755 2010-10-15 Alexei Podtelezhnikov <apodtele@gmail.com>
2757 Fix thinko in spline flattening.
2759 FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL.
2761 * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and
2762 replace it everywhere with ONE_PIXEL/8.
2764 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2766 [raccess] Skip unrequired resource access rules by Darwin VFS.
2768 When a resource fork access rule by Darwin VFS could open the
2769 resource fork but no font is found in it, the rest of rules
2770 by Darwin VFS are skipped. It reduces the warnings of the
2771 deprecated resource fork access method by recent Darwin kernel.
2772 Fix MacPorts ticket #18859:
2773 http://trac.macports.org/ticket/18859
2775 * src/base/ftobjs.c (load_face_in_embedded_rfork):
2776 When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
2777 means that the file is possible to be `fopen'-ed but zero-sized.
2778 Also there is a case that the resource fork is not zero-sized,
2779 but no supported font exists in it. If a rule by Darwin VFS
2780 falls into such cases, there is no need to try other Darwin VFS
2781 rules anymore. Such cases are marked by vfs_rfork_has_no_font.
2782 If it is TRUE, the Darwin VFS rules are skipped.
2784 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2786 [raccess] Grouping resource access rules based on Darwin VFS.
2788 MacOS X/Darwin kernel supports a few tricky methods to access
2789 a resource fork via ANSI C or POSIX interface. Current resource
2790 fork accessor tries all possible methods to support all kernels.
2791 But if a method could open a resource fork but no font is found,
2792 there is no need to try other methods older than tested method.
2793 To determine whether the rule index is for Darwin VFS, a local
2794 function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
2795 To use this function in ftobjs.c etc but it should be inlined,
2796 it is exposed by ftbase.h.
2798 * src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
2799 the rules to access the resource fork.
2800 (raccess_guess_rec): New structure to bind the rule function and
2801 rule enum type.
2802 (FT_Raccess_Guess): The list of the rule functions is replaced by
2803 (raccess_guess_table): This. This is exposed to be used by other
2804 intra module functions.
2805 (raccess_rule_by_darwin_vfs): A function to return a boolean
2806 if the rule specified by the rule index is based on Darwin VFS.
2808 2010-10-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2810 Prevent to open a FT_Stream for zero-sized file on non-Unix.
2812 builds/unix/ftsystem.c prevents to open an useless stream from
2813 zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
2814 stream drivers for ANSI C, Amiga and VMS return useless streams.
2815 For cross-platform consistency, all stream drivers should act
2816 same.
2818 * src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
2819 file is zero, FT_Err_Cannot_Open_Stream is returned.
2820 * builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
2821 * src/vms/ftsystem.c (FT_Stream_Open): Ditto.
2823 2010-10-12 Werner Lemberg <wl@gnu.org>
2825 Fix Savannah bug #31310.
2827 * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against
2828 invalid `runcnt' values.
2830 2010-10-08 Chris Liddell <chris.liddell@artifex.com>
2832 Fix Savannah bug #31275.
2834 * src/sfnt/ttpost.c: Include FT_INTERNAL_DEBUG_H.
2836 2010-10-06 Werner Lemberg <wl@gnu.org>
2838 [truetype] Improve error handling of `SHZ' bytecode instruction.
2839 Problem reported by Chris Evans <scarybeasts@gmail.com>.
2841 * src/truetype/ttinterp.c (Ins_SHZ): Check `last_point'.
2843 2010-10-05 Werner Lemberg <wl@gnu.org>
2845 Fix Savannah bug #31253.
2846 Patch submitted by an anonymous reporter.
2848 * configure: Use `awk' instead of `sed' to manipulate output of `ls
2849 -id'.

2889 2010-10-02 Werner Lemberg <wl@gnu.org>
2891 Fix Savannah bug #31088 (sort of).
2893 * src/sfnt/ttload.c (tt_face_load_maxp): Always allocate at least 64
2894 function entries.
2896 2010-10-02 Werner Lemberg <wl@gnu.org>

2900 Reported by Róbert Márki <gsmiko@gmail.com>; see
2901 http://lists.gnu.org/archive/html/freetype/2010-09/msg00019.html.
2903 * src/smooth/ftgrays.c (gray_render_cubic): Fix thinko.
2905 2010-10-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2907 Fix Savannah bug #31040.
2909 * src/truetype/ttinterp.c (free_buffer_in_size): Remove.
2910 (TT_RunIns): Updated.
2912 2010-09-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2914 [sfnt] Make error message filling NULL names less verbose.
2916 * src/sfnt/ttpost.c (load_format_20): Showing 1 summary message
2917 when we fill `post' names by NULL, instead of per-entry message.
2919 2010-09-20 Graham Asher <graham.asher@btinternet.com>
2920 David Bevan <david.bevan@pb.com>
2922 [smooth] Fix and improve spline flattening.
2924 This fixes the flattening of cubic, S-shaped curves and speeds up
2925 the handling of both the conic and cubic arcs.
2927 See the discussions on the freetype-devel mailing list in late
2928 August and September 2010 for details.
2930 * src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.
2931 (TWorker): Remove `conic_level' and `cubic_level' elements.
2932 (gray_render_conic): Simplify algorithm.
2933 (gray_render_cubic): New algorithm; details are given in the code
2934 comments.
2935 (gray_convert_glyph): Remove heuristics.
2937 2010-09-19 Werner Lemberg <wl@gnu.org>
2939 Minor fixes.
2941 * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'
2942 is `FT_UShort'.
2943 (cff_index_access_element): Don't use additions in comparison.
2944 * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type
2945 `FT_Long'.
2946 Don't use additions in comparison.
2947 Improve tracing messages.
2948 (load_format_25, load_post_names): Make `post_limit' of type
2949 `FT_Long'.
2951 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2953 [cff] Truncate the element length at the end of the stream.
2954 See Savannah bug #30975.
2956 * src/cff/cffload.c (cff_index_access_element): `off2', the offset
2957 to the next element is truncated at the end of the stream to prevent
2958 invalid I/O. As `off1', the offset to the requested element has
2959 been checked by `FT_STREAM_SEEK', `off2' should be checked
2960 similarly.
2962 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2964 [cff] Ignore CID > 0xFFFFU.
2965 See Savannah bug #30975.
2967 * src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
2968 greater than 0xFFFFU. CFF font spec does not mention maximum CID in
2969 the font, but PostScript and PDF spec define that maximum CID is
2970 0xFFFFU.
2972 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2974 [cff] Make trace message in` cff_charset_load' verbose.
2975 See Savannah bug #30975.
2977 * src/cff/cffload.c (cff_charset_load): Report the original `nleft'
2978 and truncated `nleft'.
2980 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2982 [cff] Correct `max_cid' from CID array length to max CID.
2983 See Savannah bug #30975.
2985 * src/cff/cffload.c (cff_charset_compute_cids): Don't increment
2986 max_cid after detecting max CID. The array CFF_Charset->cids is
2987 allocated by max_cid + 1.
2988 (cff_charset_cid_to_gindex): Permit CID is less than or equal to
2989 CFF_Charset->max_cid.
2990 * src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is
2991 calculated as CFF_Charset->max_cid + 1.
2993 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
2995 [truetype] Sanitize the broken offsets in `loca'.
2996 See Savannah bug #31040.
2998 * src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
2999 offset to the requested entry in `glyf' exceeds the end of the
3000 table, return offset=0, length=0. If `pos2', the offset to the next
3001 entry in `glyf' exceeds the end of the table, truncate the entry
3002 length at the end of `glyf' table.
3004 2010-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3006 [sfnt] Prevent overrunning in `post' table parser.
3007 See Savannah bug #31040.
3009 * src/sfnt/ttpost.c (load_post_names): Get the length of `post'
3010 table and pass the limit of `post' table to `load_format_20' and
3011 `load_format_25'.
3012 (load_format_20): Stop the parsing when we reached at the limit of
3013 `post' table. If more glyph names are required, they are filled by
3014 NULL names.
3016 2010-09-17 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3018 [truetype] Don't duplicate size->twilight structure to be freed.
3019 See Savannah bug #31040 for detail.
3021 * src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
3022 FT_GlyphZoneRec size->twilight to be freed. If duplicated,
3023 `FT_FREE' erases the duplicated pointers only and leave original
3024 pointers. They can cause the double-free crash when the burst
3025 errors occur in TrueType interpreter and `free_buffer_in_size' is
3026 invoked repeatedly.
3028 2010-09-15 Werner Lemberg <wl@gnu.org>
3030 Make bytecode debugging with FontForge work again.
3032 * src/truetype/ttinterp.c (TT_RunIns): Don't call
3033 `free_buffer_in_size' in case of error if a debugger is active.
3035 2010-09-14 Werner Lemberg <wl@gnu.org>
3037 Improve tracing messages.
3039 * src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
3040 message.
3041 * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
3042 tracing message.
3043 * src/truetype/ttgload.c (tt_loader_init): Add tracing message.
3044 * src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
3045 glyph doesn't fit into a small bitmap container.
3047 2010-09-13 Werner Lemberg <wl@gnu.org>
3049 Fix minor issues reported by <muktha.narayan@wipro.com>.
3051 * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
3052 redundant conditional check.
3053 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
3054 * src/cff/cffload.c (cff_encoding_load): Remove conditional check
3055 which always evaluates to `true'.
3056 * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
3057 Ditto.
3058 * src/truetype/ttinterp.c (Ins_IUP): Ditto.
3059 * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
3060 value is already dereferenced.
3061 * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
3063 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3065 Ignore the environmental setting of LIBTOOL.
3066 Patch is suggested by Adrian Bunk, to prevent unexpected
3067 reflection of environmental LIBTOOL. See:
3068 http://savannah.nongnu.org/patch/?7290
3070 * builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
3071 $(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
3072 by default.
3073 * configure: When configured for the building out of source tee,
3074 FT_LIBTOOL_DIR is set to $(OBJ_DIR).
3076 2010-08-31 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3078 [truetype] Decrease the trace level catching the interpreter error.
3080 * src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
3081 showing the error when the interpreter returns with an error,
3082 from` FT_TRACE7' to `FT_TRACE1'.
3084 2010-08-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3086 [truetype] Prevent bytecode reuse after the interpretation error.
3088 * src/truetype/ttinterp.c (free_buffer_in_size): New function to
3089 free the buffer allocated during the interpretation of this glyph.
3090 (TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
3091 an error occurs in the bytecode interpretation. The interpretation
3092 of invalid bytecode may break the function definitions and referring
3093 them in later interpretation is danger. By unsetting these flags,
3094 `fpgm' and `prep' tables are executed again in next interpretation.
3096 This fixes Savannah bug #30798, reported by Robert Święcki.
3098 2010-08-29 Werner Lemberg <wl@gnu.org>
3100 [ftraster] Pacify compiler.
3102 * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is
3103 not used.
3105 2010-08-29 Werner Lemberg <wl@gnu.org>
3107 [cff] Allow SIDs >= 65000.
3109 * src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
3110 The threshold for SIDs is not applicable here. I misinterpreted the
3111 `SID values 65000 and above are available for implementation use'
3112 sentence in the CFF specification.
3114 Problem reported by Ivan Ninčić <inincic@pdftron.com>.
3116 2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3118 Force hinting when the font lacks its familyname.
3120 In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
3121 stream may lack `name' table because they are not required. Hinting
3122 for nameless fonts is safer for PDFs including embedded Chinese
3123 fonts. Written by David Bevan, see:
3125 http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html
3126 http://lists.freedesktop.org/archives/poppler/2010-August/006310.html
3128 * src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by
3129 nameless font is given, TRUE is returned to enable hinting.
3131 2010-08-28 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3133 Register yet another tricky TrueType font.
3135 * src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?',

3185 Fix Savannah bug #30648.
3187 * src/base/ftobjs.c (FT_Done_Library): Specify the order of font
3188 drivers during the face closing process. Type42 faces should be

3311 [cff] Final try to fix `hintmask' and `cntrmask' limit check.
3313 Problem reported by Tobias Wolf <towolf@gmail.com>.
3315 * src/cff/cffgload.c (cff_decoder_parse_charstrings)
3316 <cff_op_hintmask>: Sigh. I'm apparently too silly to fix this

3399 Too serious check of errors by `FT_CMap_New' since 2010-07-04
3400 is fixed. Reported by Tor Andersson.
3402 * include/freetype/fterrdef.h
3403 (PSnames_Err_No_Unicode_Glyph_Name): New error code to
3404 indicate the Unicode charmap synthesis failed because
3405 no Unicode glyph name is found.
3407 * src/psnames/psmodule.c (ps_unicodes_init): Return
3408 PSnames_Err_No_Unicode_Glyph_Name when no Unicode glyph name

3457 * src/cff/cffgload.c (cff_decoder_parse_charstrings)
3458 <cff_op_hintmask>: It is possible that there is just a single byte
3459 after the `hintmask' or `cntrmask', e.g., a `return' instruction.

3466 * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the
3467 minimum character code passed by a legacy rogue client by...
3468 * include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
3469 This. It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
3470 undefined (thus the rogue client compatibility is not required).
3472 * src/cff/cffobjs.c (cff_face_init): Abort the automatic
3473 selection or synthesis of Unicode cmap subtable when the charmap
3474 index exceeds FT_MAX_CHARMAP_CACHEABLE.
3475 * src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message
3476 when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE.

3480 earlier one.
3481 (find_variant_selector_charmap): When UVS charmap is found after
3482 FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
3483 (FT_Select_Charmap): When a charmap matching with requested
3484 encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
3485 earlier one.
3486 (FT_Set_Charmap): When a charmap matching with requested
3487 charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
3488 earlier one.
3489 (FT_Get_Charmap_Index): When a requested charmap is found
3490 after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
3491 index.

3516 Make ftgrays.c compile stand-alone again.
3518 * src/smooth/ftgrays.c [_STANDALONE_]: Include `stddef.h'.
3519 (FT_INT_MAX, FT_PtrDist)[_STANDALONE_]: Define.
3521 2010-07-02 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3523 Additional fix for Savannah bug #30306.
3525 * src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the
3526 POST fragment is 0, the segment is completely ignored. The declared
3527 length of the segment is not cared at all. According to Adobe
3528 Technical Note 5040, type 0 segment is a comment only and should not
3529 be loaded for the interpreter. Reported by Robert Święcki.
3531 2010-07-01 Werner Lemberg <wl@gnu.org>
3533 [truetype] Protect against code range underflow.

3551 int' to avoid integer overflow.
3553 * src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller
3554 threshold values for `width' and `height'. This is not directly
3555 related to the bug fix but makes sense anyway.
3557 2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
3559 Initial fix for Savannah bug #30306.
3561 * src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the
3562 length of fragment declared in the POST fragment header, and prevent
3563 an underflow in length calculation. Some fonts set the length to
3564 zero in spite of the existence of a following 16bit `type'.
3565 Reported by Robert Święcki.

3648 * src/base/ftstream.c (FT_Stream_EnterFrame): Exit with error
3649 if the frame size is larger than the stream size.
3651 * src/base/ftsystem.c (ft_ansi_stream_io): Exit with error if
3652 seeking a position larger than the stream size.
3654 2010-06-25 Werner Lemberg <wl@gnu.org>

3875 2010-05-10 Ken Sharp <ken.sharp@artifex.com>
3877 Fix Savannah bug #29846.
3879 Previously we discovered fonts which used `setcurrentpoint' to set
3880 the initial point of a contour to 0,0. This caused FreeType to
3881 raise an error, because the `setcurrentpoint' operator is only
3882 supposed to be used with the results from an OtherSubr subroutine.
3884 This was fixed by simply ignoring the error and carrying on.
3886 Now we have found a font which uses setcurrentpoint to actually
3887 establish a non-zero point for a contour during the course of a
3888 glyph program. FWIW, these files may be produced by an application
3889 called `Intaglio' on the Mac, when converting TrueType fonts to
3890 Type 1.
3892 The fix allows the new invalid behaviour, the old invalid behaviour
3893 and real proper usage of the operator to work the same way as Adobe
3894 interpreters apparently do.
3896 (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
3897 two elements of the stack to establish unconditionally the current x
3898 and y coordinates.
3900 Make the `flex' subroutine handling (OtherSubr 0) put the current
3901 x,y coordinates onto the stack, instead of two dummy uninitialised
3902 values.
3904 2010-04-14 Ken Sharp <ken.sharp@artifex.com>
