  20. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 12.
  21. * builds/unix/configure.raw (version_info): Set to 10:0:4.
  22. 2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  23. Improve autotool version checking to work with beta releases.
  24. * autogen.sh (check_tool_version): Improve the extraction of version
  25. number from "tool --version" output. Some beta releases of
  26. autotools have extra strings before version number.
  27. 2010-02-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  28. Fix overallocating bug in FT_Outline_New_Internal().
  29. * src/base/ftoutln.c (FT_Outline_New_Internal): The length of
  30. FT_Outline->points[] should be numPoints, not 2 * numPoints.
  31. Found by Paul Messmer, see
  32. http://lists.gnu.org/archive/html/freetype-devel/2010-02/msg00003.html
  33. 2010-02-10 Ken Sharp <ken.sharp@artifex.com>
  34. Really fix Savannah bug #28678 (part 2).
  35. Since we consider `sbw' for the horizontal direction only, we still have
  36. to synthesize vertical metrics if the user wants to use the vertical
  37. writing direction.
  38. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
  39. (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph):
  40. Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is
  41. set.
  42. 2010-02-10 Ken Sharp <ken.sharp@artifex.com>
  43. Really fix Savannah bug #28678 (part 1).
  44. After long discussion, we now consider the character width vector
  45. (wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
  46. direction only. For example, if you are using the horizontal
  47. writing direction, you get the horizontal and vertical components of
  48. the advance width for this direction. Note that OpenType and CFF fonts
  49. don't have such a vertical component; instead, the GPOS table can be
  50. used to generate two-dimensional advance widths (but this isn't
  51. handled by FreeType).
  52. * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
  53. `advance_v' field to hold the vertical component of the advance
  54. value.
  55. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
  56. (cff_slot_load), src/type1/t1gload.c
  57. (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c
  58. (cid_load_glyph): Use it.
  59. 2010-02-08 Werner Lemberg <wl@gnu.org>
  60. * devel/ftoption.h [FT_CONFIG_OPTION_PIC]: Define.
  61. 2010-02-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  62. Prevent NULL pointer dereference passed to FT_Module_Requester.
  63. * src/sfnt/sfdriver.c (sfnt_get_interface): Don't use `module'.
  64. * src/psnames/psmodule.c (psnames_get_interface): Ditto.
  65. * src/cff/cffdrivr.c (cff_get_interface): Check NULL `driver'.
  66. * src/truetype/ttdriver.c (tt_get_interface): Ditto.
  67. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  68. Fix memory leaks in previous patch.
  69. * src/sfnt/sfobjs.c (sfnt_load_face): Don't overwrite the strings
  70. allocated for face->root.family_name and style_name.
  71. 2010-01-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  72. New parameters for FT_Open_Face() to ignore preferred family names.
  73. Preferred family names should be used for legacy systems that
  74. can hold only a few faces (<= 4) for a family name. Suggested by
  75. Andreas Heinrich.
  76. http://lists.gnu.org/archive/html/freetype/2010-01/msg00001.html
  77. * include/freetype/ftsnames.h (FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
  78. FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY): Define.
  79. * src/sfnt/sfobjs.c (sfnt_load_face): Check the arguments and
  80. ignore preferred family and subfamily names if requested.
  81. 2010-01-27 Ken Sharp <ken.sharp@artifex.com>
  82. Fix Savannah bug #28678.
  83. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c
  84. (cid_load_glyph): Handle vertical metrics correctly.
  85. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle
  86. vertical metrics correctly.
  87. (T1_Load_Glyph): Don't synthesize vertical metrics.
  88. 2010-01-14 Werner Lemberg <wl@gnu.org>
  89. Make FT_Set_Transform work if no renderer is available.
  90. * src/base/ftobjs.c (FT_Load_Glyph): Apply `standard' transformation
  91. if no renderer is compiled into the library.
  92. 2010-01-14 Werner Lemberg <wl@gnu.org>
  93. Fix compilation warning.
  94. * src/base/ftbase.h: s/LOCAL_DEF/LOCAL/.
  95. * src/base/ftobjc.s: Include ftbase.h conditionally.
  96. 2010-01-11 Kwang Yul Seo <skyul@company100.net>
  97. Provide inline assembly code for RVCT compiler.
  98. This is Savannah patch #7059.
  99. * include/freetype/config/ftconfig.h (FT_MULFIX_ASSEMBLER,
  100. FT_MulFix_arm) [__CC_ARM || __ARM_CC]: Define.

  102. Fix Savannah bug #28521.
  103. Issue #28226 involved a work-around for a font which used the
  104. `setcurrentpoint' operator in an invalid way; this operator is only
  105. supposed to be used with the result of OtherSubrs, and the font used
  106. it directly. The supplied patch removed the block of code which
  107. checked this usage entirely.
  108. This turns out to be a Bad Thing. If `setcurrentpoint' is being
  109. used correctly it should reset the flex flag in the decoder. If we
  110. don't do this then the flag never gets reset and we omit any further
  111. contours from the glyph (at least until we close the path or
  112. similar).
  113. * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
  114. <op_setcurrentpoint>: Handle `flex_state' correctly.
  115. 2010-01-05 Werner Lemberg <wl@gnu.org>
  116. Apply reports from clang static analyzer.
  117. * src/lzw/ftlzw.c (ft_lzw_file_init), src/base/ftstroke.c
  118. (FT_Stroker_ParseOutline), src/base/ftsynth.c
  119. (FT_GlyphSlot_Embolden): Remove dead code.
  120. * src/base/ftpatent.c (_tt_check_patents_in_table): Initialize
  121. `offset_i' and `length_i'.
  122. 2010-01-05 Ralph Giles <giles@ghostscript.com>
  123. Enable the incremental font interface by default.
  124. Ghostscript requires the incremental font interface for handling
  125. some Postscript documents. It is moving to using FreeType as its
  126. primary renderer; supporting this in the default build makes it
  127. Ghostscript to be linked against the system FreeType when one is
  128. available.
  129. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_INCREMENTAL):
  130. Uncomment.
  131. 2010-01-05 Werner Lemberg <wl@gnu.org>
  132. Fix Savannah bug #28395.
  133. * src/truetype/ttdriver.c (Load_Glyph), src/type1/t1gload.c
  134. (T1_Loada_Glyph): Don't check `num_glyphs' if incremental interface
  135. is used.
  136. 2010-01-05 Ken Sharp <ken.sharp@artifex.com>
  137. Make Type 1 `seac' operator work with incremental interface.
  138. This fixes Savannah bug #28480.
  139. * src/psaux/t1decode.c (t1operator_seac): Don't check `glyph_names'
  140. if incremental interface is used.
  141. 2010-01-04 Ken Sharp <ken.sharp@artifex.com>
  142. Make incremental interface work with TrueType fonts.
  143. This fixes Savannah bug #28478.
  144. * src/truetype/ttgload.c (load_truetype_glyph): Don't check
  145. `glyf_offset' if incremental interface is used.
  146. 2009-12-31 Lars Abrahamsson <wonko@opera.com>
  147. Make compilation with FT_CONFIG_OPTION_PIC work again.
  148. * src/base/ftglyph.c (FT_Glyph_To_Bitmap) [FT_CONFIG_OPTION_PIC]:
  149. Declare `library' for FT_BITMAP_GLYPH_CLASS_GET.
  150. * src/base/ftinit.c (ft_destroy_default_module_classes,
  151. ft_create_default_module_classes): Use proper casts (needed for C++
  152. compilation).
  153. * src/sfnt/ttcmap.c (tt_cmap13_class_rec): Use FT_DEFINE_TT_CMAP.
  154. 2009-12-22 Marc Kleine-Budde <mkl@pengutronix.de>
  155. Make freetype-config aware of $SYSROOT.
  156. This is Savannah patch #7040.
  157. * builds/unix/freetype-config.in: Decorate with ${SYSROOT} where
  158. appropriate.
  159. 2009-12-20 Werner Lemberg <wl@gnu.org>
  160. Fix compiler warning.
  161. Reported by Sean.
  162. * src/base/ftdbgmem.c [!FT_DEBUG_MEMORY]: ANSI C doesn't like empty
  163. source files; however, some compilers warn about an unused variable
  164. declaration. This is now replaced with a typedef.
  165. 2009-12-18 Werner Lemberg <wl@gnu.org>
  166. Fix Savannah bug #28320.
  167. There exist corrupt, subsetted fonts (embedded in PDF files) which
  168. contain a private dict that ends with an unterminated floating point
  169. number (no operator following). We now ignore this error (as
  170. acrobat does).
  171. * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for
  172. unterminated floating point numbers.
  173. 2009-12-16 Werner Lemberg <wl@gnu.org>
  174. Really fix compiler warnings.
  175. Reported by Sean.
  176. * src/truetype/ttgxvar.c (GX_PT_POINTS_ARE_WORDS,
  177. GX_PT_POINT_RUN_COUNT_MASK): Convert enum values to macros.
  178. 2009-12-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  179. Improve configure.raw to copy some options from CFLAGS to LDFLAGS.
  180. The linker of Mac OS X 10.6 is sensitive to the architecture. If
  181. the architectures are specified explicitly for the C compiler, the
  182. linker requires the architecture specifications too.
  183. * builds/unix/configure.raw: Replace `-isysroot' option parser by
  184. more generic argument parser.
  185. 2009-12-15 Werner Lemberg <wl@gnu.org>
  186. Fix compiler warnings.
  187. Reported by Sean.
  188. * src/truetype/ttgxvar.c (ft_var_readpackeddeltas): Fix counter data
  189. type.
  190. 2009-12-14 Ken Sharp <ken.sharp@artifex.com>
  191. Ignore invalid `setcurrentpoint' operations in Type 1 fonts.
  192. This fixes Savannah bug #28226.
  193. At least two wild PostScript files of unknown provenance contain
  194. Type 1 fonts, apparently converted from TrueType fonts in earlier
  195. PDF versions of the files, which use the `setcurrentpoint' operator
  196. inappropriately.
  197. FreeType currently throws an error in this case, but Ghostscript and
  198. Adobe Distiller both accept the fonts and ignore the problem. This
  199. commit #ifdefs out the check so PostScript interpreters using
  200. FreeType can render these files.
  201. The specification says `setcurrentpoint' should only be used to set
  202. the point after a `Subr' call, but these fonts use it to set the
  203. initial point to (0,0). Unnecessarily so, as they correctly use an
  204. `hsbw' operation which implicitly sets the initial point.
  205. * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
  206. <op_setcurrentpoint>: Comment out code.
  207. 2009-12-14 Bram Tassyns <bramt@enfocus.be>
  208. Fix parsing of /CIDFontVersion.
  209. This fixes Savannah bug #28287.
  210. * src/cid/cidtoken.h: `cid_version' in CID_FaceInfoRec (in
  211. t1tables.h) is of type FT_Fixed.
  212. 2009-12-14 Werner Lemberg <wl@gnu.org>
  213. Trace glyph index in CID module.
  214. Suggested in Savannah patch #7023.
  215. * src/cid/cidgload.c (cid_load_glyph): Add tracing message.
  216. 2009-12-03 Werner Lemberg <wl@gnu.org>
  217. Fix compiler warnings.
  218. * src/truetype/ttgload.c (tt_get_metrics): Put `Exit' label into the
  219. proper preprocessor conditional.
  220. * src/pfr/pfrobjs.c (pfr_slot_load): Pacify gcc.

  224. * src/type1/t1parse.c (T1_Get_Private_Dict): Skip all whitespace
  225. characters before start of `eexec' section.
  226. 2009-11-20 Werner Lemberg <wl@gnu.org>

  256. Fix Savannah bug #27921.
  257. * src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c
  258. (cid_face_init), src/type1/t1afm.c (T1_Read_Metrics),

  344. [cache] Fix Savannah bug #27441, clean up Redhat bugzilla #513582.
  345. Tricky casts in FTC_{CACHE,GCACHE,MRULIST}_LOOKUP_CMP() are removed.
  346. Now these functions should be called with FTC_Node or FTC_MruNode
  347. variable, and the caller should cast them to appropriate pointers to
  348. concrete data. These tricky casts can GCC-4.4 optimizer (-O2)
  349. confused and the crashing binaries are generated.
  350. * src/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Drop tricky cast.
  351. Now the 4th argument `node' of this function should be typed as
  352. FTC_MruNode.
  353. * src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): For inline
  354. implementation, new temporal variable FTC_MruNode `_mrunode' to take
  355. the pointer from FTC_MRULIST_LOOKUP_CMP(). For non-inline
  356. implementation, tricky cast is dropped.
  357. * src/cache/ftcmanag.c (FTC_SIZE_NODE): New macro casting
  358. to FTC_SizeNode.
  359. (FTC_Manager_LookupSize): Replace FTC_SizeNode `node' by FTC_MruNode
  360. `mrunode', and FTC_SIZE_NODE() is inserted.
  361. (FTC_FACE_NODE): New macro casting to FTC_FaceNode.
  362. (FTC_Manager_LookupFace) Replace FTC_FaceNode `node' by FTC_MruNode
  363. `mrunode', and FTC_FACE_NODE() is inserted.
  364. * src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Change the type of
  365. `node' from FTC_INode to FTC_Node. Extra casting macro FTC_NODE()
  366. is dropped.
  367. (FTC_ImageCache_LookupScaler): Ditto.
  368. (FTC_SBitCache_Lookup): Change the type of `node' from FTC_SNode to
  369. FTC_Node. Extra casting macro FTC_NODE() is dropped. FTC_SNODE()
  370. is inserted.
  371. (FTC_SBitCache_LookupScaler): Ditto.
  372. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the type of
  373. `node' from FTC_CMapNode to FTC_Node. Extra casting macro
  374. FTC_NODE() is dropped, FTC_CMAP_NODE() is inserted.
  375. 2009-09-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  376. [cache, psaux, type1] Fix for multi build.
  377. In multi build, some cpp functions are left as unresolved symbols.

  383. 2009-09-25 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  384. [autofit] Fix for multi build.
  385. * src/autofit/afmodule.h: Include FT_INTERNAL_OBJECTS_H to use
  386. FT_DECLARE_MODULE() macro in multi build.
  387. * src/autofit/aflatin.c: Include <ft2build.h> to handle
  388. FT_ADVANCES_H correctly in multi build.
  389. 2009-09-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  390. [cache] Check the face filled by FTC_Manager_LookupFace().
  391. * src/cache/ftcbasic.c (ftc_basic_family_get_count): Return
  392. immediately if FTC_Manager_LookupFace() fills face by NULL. Such
  393. case can occur when the code is optimized by GCC-4.2.x.
  394. 2009-09-23 Werner Lemberg <wl@gnu.org>
  395. * docs/CHANGES: Updated.
  396. 2009-09-12 Werner Lemberg <wl@gnu.org>
  397. [raster] Fix 5-levels grayscale output.
  398. This was broken since version 2.3.0.
  399. * src/raster/ftraster.c (count_table): Use pre-2.3.0 values (which
  400. were then computed dynamically).
  401. (Vertical_Gray_Sweep_Step): Updated.
  402. (ft_black_render): Initialize `worker->gray_lines' (problem found by
  403. valgrind).
  404. (FT_RASTER_OPTION_ANTI_ALIASING, DEBUG_RASTER): Dont' #undef, just
  405. comment out.
  406. 2009-09-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  407. Improve configure.raw for cross build.
  408. * builds/unix/configure.raw: Remove temporal files created by the
  409. suffix checking for CC_BUILD. Set XX_ANSIFLAGS and XX_CFLAGS when
  410. cross compiler is GCC. AC_PROG_CC checks whether the cross compiler
  411. is GCC, its result is stored in GCC.
  412. 2009-09-12 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  413. [BDF] Modify hash API to take size_t value instead of void *.
  414. The hash API in BDF driver is designed to be generic, it takes
  415. void * typed data. But BDF driver always gives an unsigned long
  416. integer (the index to a property). To reduce non-essential
  417. casts from unsigned long to void* and from void* to unsigned
  418. long, the hash API is changed to take size_t integer.
  419. The issue of incompatible cast between unsigned long and void*
  420. on LLP64 platform is reported by NightStrike from MinGW-Win64
  421. project. See
  422. http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html
  423. * src/bdf/bdf.h: The type of hashnode->data is changed from
  424. void* to size_t.
  425. * src/bdf/bdflib.c (hash_insert): Get size_t data, instead of
  426. void* data.
  427. (bdf_create_property): Get the name length of new property by
  428. size_t variable, with a cut-off at FT_ULONG_MAX.
  429. (_bdf_set_default_spacing): Get the name length of the face by
  430. size_t variable, with a cut-off at 256.
  431. (bdf_get_property): Get the property id by size_t variable to
  432. reduce the casts between 32-bit prop ID & hashnode->data during
  433. simple copying.
  434. (_bdf_add_property): Ditto.
  435. (_bdf_parse_start): Calculate the index to the property array
  436. by size_t variable.
  437. (bdf_get_font_property): Drop a cast to unsigned long.
  438. 2009-09-10 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  439. [Win64] Improve the computation of random seed from stack address.
  440. On LLP64 platform, the conversion from pointer to FT_Fixed need
  441. to drop higher 32-bit. Explict casts are required. Reported by
  442. NightStrike from MinGW-w64 project. See
  443. http://lists.gnu.org/archive/html/freetype/2009-09/msg00000.html

  453. Improve vertical metrics calculation (Savannah bug #27364).
  454. The calculation of `vertBearingX' is not defined in the OTF font
  455. spec so FreeType does a `best effort' attempt. However, this value
  456. is defined in the PDF and PostScript specs, and that algorithm is
  457. better than the one FreeType currently uses:
  458. FreeType: Use the middle of the bounding box as the X coordinate
  459. of the vertical origin.
  460. Adobe PDF spec: Use the middle of the horizontal advance vector as
  461. the X coordinate of the vertical origin.
  462. FreeType's algorithm goes wrong if you have a really small glyph
  463. (like the full-width, circle-like dot at the end of the sentence, as
  464. used in CJK scripts) with large bearings. With the FreeType
  465. algorithm this dot gets centered on the baseline; with the PDF
  466. algorithm it gets the correct location (in the top right). Note
  467. that this is a serious issue, it's like printing the dot at the end
  468. of a Roman sentence at the center of the textline instead of on the
  469. baseline like it should. So i believe the PDF spec's algorithm
  470. should be used in FreeType as well.
  471. The `vertBearingY' value for such small glyphs is also very strange
  472. if no `vmtx' information is present, since the height of the bbox is
  473. not representable for the height of the glyph visually (the
  474. whitespace up to the baseline is part of the glyph). The fix also
  475. includes some code for a better estimate of `vertBearingY'.
  476. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
  477. is now calculated as described by the Adobe PDF Spec. Estimate for
  478. `vertBearingY' now works better for small glyphs completely above or
  479. below the baseline into account.
  480. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
  481. calculated as described by the Adobe PDF Spec. Vertical metrics
  482. information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
  483. was not defined.
  484. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
  485. now calculated as described by the Adobe PDF Spec.

  1408. Filter --srcdir= option before invoking builds/unix/configure.
  1409. * configure: If builds/unix/configure is invoked with --srcdir
  1410. option, the option should take `builds/unix' directory instead of
  1411. the top source directory. Thus the configure script in the top
  1412. directory should modify the --srcdir= option if
  1413. `builds/unix/configure' is invoked.

  1433. Use 16.16 format while parsing Type 1 charstrings.
  1434. This fixes Savannah bug #26867.
  1435. Previously, only integers have been used which can lead to serious
  1436. rounding errors.
  1437. However, fractional values are only used internally; after the
  1438. charstrings (of either Type 1 or 2) have been processed, the
  1439. resulting coordinates get rounded to integers currently -- before
  1440. applying scaling. This should be fixed; at the same time a new load
  1441. flag should be introduced, to be used in combination with
  1442. FT_LOAD_NO_SCALE, which indicates that font units are returned in
  1443. 16.16 format. Similarly, the incremental interface should be
  1444. extended to allow fractional values for metrics.

  1513. 2009-06-18 Werner Lemberg <wl@gnu.org>
  1514. Fix B/W rasterization of subglyphs with different drop-out modes.
  1515. Normally, the SCANMODE instruction (if present) to set the drop-out
  1516. mode in a TrueType font is located in the `prep' table only and thus
  1517. valid for all glyphs. However, there are fonts like `pala.ttf'
  1518. which additionally contain this instruction in the hinting code of
  1519. some glyphs (but not all). As a result it can happen that a
  1520. composite glyph needs multiple drop-out modes for its subglyphs
  1521. since the rendering state gets reset for each subglyph.
  1522. FreeType collects the hinted outlines from all subglyphs, then it
  1523. sends the data to the rasterizer. It also sends the drop-out mode
  1524. -- after hinting has been applied -- and here is the error: It sends
  1525. the drop-out mode of the last subglyph only; drop-out modes of all
  1526. other subglyphs are lost.
  1527. This patch fixes the problem; it adds a second, alternative
  1528. mechanism to pass the drop-out mode: For each contour, the
  1529. rasterizer now checks the first `tags' array element. If bit 2 is
  1530. set, bits 5-7 contain the contour's drop-out mode, overriding the
  1531. global drop-out mode.
  1532. * include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.
  1533. * src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
  1534. `tags[0]'.
  1535. * src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
  1536. Use bits 3-5 instead of 0-2.
  1537. (New_Profile): Set the drop-out mode in the profile's `flags' field.
  1538. (Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
  1539. necessary.
  1540. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
  1541. Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
  1542. mode.
  1543. 2009-06-16 Werner Lemberg <wl@gnu.org>
  1544. Improve scan conversion rules 4 and 6.
  1545. Two new constraints are introduced to better identify a `stub' -- a
  1546. concept which is only vaguely described in the OpenType
  1547. specification. The old code was too rigorous and suppressed more
  1548. pixel than it should.
  1549. . The intersection of the two profiles with the scanline is less
  1550. than a half pixel. Code related to this was already present in
  1551. the sources but has been commented out.
  1552. . The endpoint of the original contour forming a profile has a
  1553. distance (`overshoot') less than half a pixel to the scanline.
  1554. Note that the two additional conditions fix almost all differences
  1555. to the Windows rasterizer, but some problematic cases remain.
  1556. * src/raster/ftraster.c (Overshoot_Top, Overshoot_Bottom): New
  1557. macros for the `flags' field in the `TProfile' structure.
  1558. (IS_BOTTOM_OVERSHOOT, IS_TOP_OVERSHOOT): New macros.
  1559. (New_Profile, End_Profile): Pass overshoot flag as an argument and
  1560. set it accordingly.
  1561. Update callers.
  1562. (Vertical_Sweep_Drop, Horizontal_Sweep_Drop): Implement the two new
  1563. constraints.
  1564. 2009-06-11 Werner Lemberg <wl@gnu.org>
  1565. Increase precision for B/W rasterizer.
  1566. * src/raster/ftraster.c (Set_High_Precision): Add two more bits to
  1567. the precision. This corrects rendering of some small glyphs, for
  1568. example, glyph `xi' in verdana.ttf at 13 ppem. Testing with ftbench
  1569. on my GNU/Linux box I don't see a performance degradation.

  2180. * src/sfnt/rules.mk (SFNT_DRV_H): Add ttsbit0.c.
  2181. 2009-03-09 Alexey Kryukov <anagnost@yandex.ru>
  2182. Fix handling of EBDT formats 8 and 9 (part 2).
  2183. This patch fixes the following problems in ttsbit0.c:
  2184. . Bitmaps for compound glyphs were never allocated.
  2185. . `SBitDecoder' refused to load metrics if some other metrics have
  2186. already been loaded. This condition certainly makes no sense for
  2187. recursive calls, so I've just disabled it. Another possibility
  2188. would be resetting `decoder->metrics_loaded' to false before
  2189. loading each composite component. However, we must restore the
  2190. original metrics after finishing the recursion; otherwise we can
  2191. get a misaligned glyph.
  2192. . `tt_sbit_decoder_load_bit_aligned' incorrectly handled `x_pos',
  2193. causing some glyph components to be shifted too far to the right
  2194. (especially noticeable for small sizes).
  2195. Note that support for grayscale bitmaps (not necessarily compound) is
  2196. completely broken in ttsbit0.c.
  2197. * src/sfnt/tt_sbit_decoder_load_metrics: Always load metrics.
  2198. (tt_sbit_decoder_load_bit_aligned): Handle `x_pos' correctly in case
  2199. of `h == height'.
  2200. (tt_sbit_decoder_load_compound): Reset metrics after loading
  2201. components.
  2202. Allocate bitmap.
  2203. 2009-03-09 Werner Lemberg <wl@gnu.org>
  2204. * builds/unix/configure.raw (version_info): Set to 9:20:3.
  2205. 2009-03-03 David Turner <david@freetype.org>
  2206. Protect SFNT kerning table parser against malformed tables.
  2207. This closes Savannah BUG #25750.
  2208. * src/sfnt/ttkern.c (tt_face_load_kern, tt_face_get_kerning): Fix a
  2209. bug where a malformed table would be successfully loaded but later
  2210. crash the engine during parsing.
  2211. 2009-03-03 David Turner <david@freetype.org>
  2212. Update documentation and bump version number to 2.3.9.
  2213. * include/freetype/freetype.h: Bump patch version to 9.
  2214. * docs/CHANGES: Document the ABI break in 2.3.8.
  2215. * docs/VERSION.DLL: Update version numbers table for 2.3.9.
  2216. 2009-03-03 David Turner <david@freetype.org>
  2217. Remove ABI-breaking field in public PS_InfoFontRec definition.
  2218. Instead, we define a new internal PS_FontExtraRec structure to
  2219. hold the additional field, then place it in various internal
  2220. positions of the corresponding FT_Face derived objects.
  2221. * include/freetype/t1tables.h (PS_FontInfoRec): Remove the
  2222. `fs_type' field from the public structure.
  2223. * include/freetype/internal/psaux.h (T1_FieldLocation): New

  2246. 2009-03-02 Alexey Kryukov <anagnost@yandex.ru>
  2247. Fix handling of EBDT formats 8 and 9.
  2248. The main cycle in `blit_sbit' makes too many iterations: it actually
  2249. needs the count of lines in the source bitmap rather than in the
  2250. target image.
  2251. * src/sfnt/ttsbit.c (blit_sbit) [FT_CONFIG_OPTION_OLD_INTERNALS]:
  2252. Add parameter `source_height' and use it for main loop.
  2253. (Load_SBit_Single) [FT_CONFIG_OPTION_OLD_INTERNALS]: Updated.
  2254. 2009-02-23 Werner Lemberg <wl@gnu.org>

  2270. Fix Savannah bug #25495.
  2271. * src/sfnt/sfobjs.c (sfnt_load_face): Test for bitmap strikes before
  2272. setting metrics and bbox values. This ensures that the check for a
  2273. font with neither a `glyf' table nor bitmap strikes can be performed
  2274. early enough to set metrics and bbox values too.
  2275. 2009-02-04 Werner Lemberg <wl@gnu.org>
  2276. Fix Savannah bug #25480.
  2277. * builds/unix/freetype-config.in: For --ftversion, don't use $prefix

  2440. * src/base/ftpfr.c (FT_Get_PFR_Metrics): Protect against NULL
  2441. arguments.
  2442. Fix return value for non-PFR fonts. Both problems reported by Chi
  2443. Nguyen <chint@necsv.com>.

  2445. FT_USE_MODULE declares things as:
  2446. extern const FT_Module_Class
  2447. (or similar for C++). However, the actual types of the variables
  2448. being declared are often different, e.g., FT_Driver_ClassRec or
  2449. FT_Renderer_Class. (Some are, indeed, FT_Module_Class.)
  2450. This works with most C compilers (since those structs begin with an
  2451. FT_Module_Class struct), but technically it's undefined behavior.
  2452. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7
  2453. paragraph 2:
  2454. All declarations that refer to the same object or function shall
  2455. have compatible type; otherwise, the behavior is undefined.
  2456. (And they are not compatible types.)
  2457. Most C compilers don't reject (or even detect!) code which has this
  2458. issue, but the GCC LTO development branch compiler does. (It
  2459. outputs the types of the objects while generating .o files, along
  2460. with a bunch of other information, then compares them when doing the
  2461. final link-time code generation pass.)
  2462. Patch from Savannah bug #25133.
  2463. * src/base/ftinit.c (FT_USE_MODULE): Include variable type.
  2464. * builds/amiga/include/freetype/config/ftmodule.h,
  2465. include/freetype/config/ftmodule.h, */module.mk: Updated to declare
  2466. pass correct types to FT_USE_MODULE.
  2467. 2008-12-21 Hongbo Ni <hongbo@njstar.com>

  2470. (af_cjk_hint_edges): Protect against division by zero. This fixes
  2471. Savannah bug #25124.
  2472. 2008-12-18 Werner Lemberg <wl@gnu.org>
  2473. * docs/CHANGES: Updated.
  2474. 2008-12-18 Bevan, David <dbevan@emtex.com>
  2475. Provide API for accessing embedding and subsetting restriction
  2476. information.
  2477. * include/freetype.h (FT_FSTYPE_INSTALLABLE_EMBEDDING,
  2478. FT_FSTYPE_RESTRICTED_LICENSE_EMBEDDING,
  2479. FT_FSTYPE_PREVIEW_AND_PRINT_EMBEDDING, FT_FSTYPE_EDITABLE_EMBEDDING,
  2480. FT_FSTYPE_NO_SUBSETTING, FT_FSTYPE_BITMAP_EMBEDDING_ONLY): New
  2481. macros.
  2482. (FT_Get_FSType_Flags): New function declaration.
  2483. * src/base/ftobjs.c (FT_Get_FSType_Flags): New function.

  2486. * include/freetype/t1tables.h (PS_FontInfoRec): Add `fs_type' field.
  2487. 2008-12-17 Werner Lemberg <wl@gnu.org>
  2488. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Don't use internal
  2489. macros so that copying the source code into an application works
  2490. out of the box.
  2491. 2008-12-17 Werner Lemberg <wl@gnu.org>
  2492. * include/freetype/ftsynth.h, src/base/ftsynth.c: Move
  2493. FT_GlyphSlot_Own_Bitmap to...

  2495. * docs/CHANGES: Document it.
  2496. 2008-12-10 Werner Lemberg <wl@gnu.org>
  2497. Generalize the concept of `tricky' fonts by introducing
  2498. FT_FACE_FLAG_TRICKY to indicate that the font format's hinting
  2499. engine is necessary for correct rendering.
  2500. At the same time, slightly modify the behaviour of tricky fonts:
  2501. FT_LOAD_NO_HINTING is now ignored. To really force raw loading
  2502. of tricky fonts (without hinting), both FT_LOAD_NO_HINTING and
  2503. FT_LOAD_NO_AUTOHINT must be used.
  2504. Finally, tricky TrueType fonts always use the bytecode interpreter
  2505. even if the patented code is used.
  2506. * include/freetype/freetype.h (FT_FACE_FLAG_TRICKY, FT_IS_TRICKY):
  2507. New macros.
  2508. * src/truetype/ttdriver.c (Load_Glyph): Handle new load flags
  2509. semantics as described above.
  2510. * src/truetype/ttobjs.c (tt_check_trickyness): New function, using
  2511. code of ...
  2512. (tt_face_init): This function, now simplified and updated to new
  2513. semantics.
  2514. * src/base/ftobjs.c (FT_Load_Glyph): Don't use autohinter for tricky
  2515. fonts.
  2516. * docs/CHANGES: Document it.
  2517. 2008-12-09 Werner Lemberg <wl@gnu.org>
  2518. Really fix Savannah bug #25010: An SFNT font with neither outlines
  2519. nor bitmaps can be considered as containing space `glyphs' only.
  2520. * src/truetype/ttpload.c (tt_face_load_loca): Handle the case where
  2521. a `glyf' table is missing.
  2522. * src/truetype/ttgload.c (load_truetype_glyph): Abort if we have no
  2523. `glyf' table but a non-zero `loca' entry.
  2524. (tt_loader_init): Handle missing `glyf' table.
  2525. * src/base/ftobjs.c (FT_Load_Glyph): Undo change 2008-12-05.
  2526. * src/sfnt/sfobjs.c (sfnt_load_face): A font with neither outlines
  2527. nor bitmaps is scalable.
  2528. 2008-12-05 Werner Lemberg <wl@nu.org>
  2529. * src/autofit/aflatin.c (af_latin_uniranges): Add more ranges. This
  2530. fixes Savannah bug #21190 which also provides a basic patch.
  2531. 2008-12-05 Werner Lemberg <wl@nu.org>
  2532. * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): Use value
  2533. 0x100 instead of 0x10000; the latter value is already occupied by
  2534. FT_LOAD_TARGET_LIGHT. Bug reported by James Cloos.
  2535. Handle SFNT with neither outlines nor bitmaps. This fixes Savannah
  2536. bug #25010.
  2537. * src/base/ftobjs.c (FT_Load_Glyph): Reject fonts with neither
  2538. outlines nor bitmaps.
  2539. * src/sfnt/sfobjs.c (sfnt_load_face): Don't return an error if there
  2540. is no table with glyphs.
  2541. * src/sfnt/ttload.c (tt_face_lookup_table): Improve debugging
  2542. message.
  2543. 2008-12-01 Werner Lemberg <wl@gnu.org>
  2544. GDEF tables need `glyph_count' too for validation. Problem reported
  2545. by Chi Nguyen <chint@necsv.com>.
  2546. * src/otvalid/otvgdef.c (otv_GDEF_validate), src/otvalid/otvalid.h
  2547. (otv_GDEF_validate), src/otvalid/otvmod.c (otv_validate): Pass

  2555. (Atari PureC).
  2556. 2008-11-29 James Cloos <cloos@jhcloos.com>
  2557. * src/type/t1load.c (mm_axis_unmap): Revert previous patch and fix
  2558. it correctly by using FT_INT_TO_FIXED (FreeType expects 16.16 values
  2559. in the /BlendDesignMap space).
  2560. 2008-11-29 James Cloos <cloos@jhcloos.com>
  2561. * src/type1/t1load.c (mm_axis_unmap): `blend_points' is FT_Fixed*,
  2562. whereas `design_points' is FT_Long*. Therefore, return blend rather
  2563. than design points.
  2564. 2008-11-27 Werner Lemberg <wl@gnu.org>
  2565. * src/cff/cffparse.c (cff_parse_real): Handle more than nine

  2660. `SING') are missing. Other errors are returned by
  2661. SFNT_Err_Unknown_File_Format.
  2662. * src/base/ftobjs.c (FT_Open_Face): When TrueType driver returns
  2663. `FT_Err_Table_Missing', try `open_face_PS_from_sfnt_stream'. It is

  2737. (memory_stream_close): Build on any platform when old MacOS font
  2738. support is enabled.
  2739. (new_memory_stream): Ditto.
  2740. (open_face_from_buffer): Build on any platform when old MacOS font
  2741. support is enabled. The counting of the face in a font file is
  2742. slightly different between Carbon-dependent parser and Carbon-free
  2743. parser. They are merged with the platform-specific conditional.
  2744. (ft_lookup_PS_in_sfnt): Ditto.
  2745. * src/base/ftmac.c: Include ftbase.h.
  2746. (memory_stream_close): Removed.
  2747. (new_memory_stream): Ditto.
  2748. (open_face_from_buffer): Removed. Use the implementation in
  2749. ftobjs.c.
  2750. (ft_lookup_PS_in_sfnt): Ditto.
  2751. 2008-10-02 Werner Lemberg <wl@gnu.org>
  2752. * src/sfnt/sfobjs.c (sfnt_load_face): `psnames_error' is only needed
  2753. if TT_CONFIG_OPTION_POSTSCRIPT_NAMES is defined.
  2754. 2008-10-01 Werner Lemberg <wl@gnu.org>
  2755. * src/truetype/ttobjs.c (tt_face_done), src/cff/cffobjs.c
  2756. (cff_face_done), src/pfr/pfrobjs.c (pfr_face_done),
  2757. src/pcf/pcfdrivr.c (PCF_Face_Done), src/cid/cidobjs.c
  2758. (cid_face_done), src/bdf/bdfdrivr. (BDF_Face_Done),
  2759. src/sfnt/sfobjs.c (sfnt_face_done): Protect against face == 0.
  2760. Reported by Graham Asher.
  2761. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2762. * src/base/rules.mk: Add conditional source to BASE_SRC, for `make
  2763. multi' on Mac OS X. If the macro $(ftmac_c) is defined,
  2764. $(BASE_DIR)/$(ftmac_c) is added to BASE_SRC. In a normal build, the
  2765. lack of ftmac.c in BASE_SRC is not serious because ftbase.c includes
  2766. ftmac.c.
  2767. * builds/unix/unix-def.in: Add a macro definition of $(ftmac_c).
  2768. * builds/unix/configure.raw: Add procedure to set up appropriate
  2769. value of $(ftmac_c) with the consideration of the availability of
  2770. Carbon framework.
  2771. 2008-09-30 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2772. * src/base/Jamfile: Add target for multi build by jam on Mac OS X.
  2773. * src/base/ftobjs.c (FT_New_Face): Fix the condition to include this
  2774. function for MPW building. It is synchronized the condition to
  2775. include ftmac.c source into ftbase.c.
  2776. 2008-09-22 Werner Lemberg <wl@gnu.org>
  2777. * src/cff/cffgload.c (CFF_Operator, cff_argument_counts,
  2778. cff_decoder_parse_charstrings): Handle (invalid)
  2779. `callothersubr' and `pop' instructions.
  2780. 2008-09-22 John Tytgat <John.Tytgat@esko.com>
  2781. Fix Savannah bug #24307.
  2782. * include/freetype/internal/t1types.h (CID_FaceRec),
  2783. src/type42/t42types.h (T42_FaceRec): Comment out `afm_data'.
  2784. 2008-09-21 Werner Lemberg <wl@gnu.org>
  2785. * src/smooth/ftgrays.c (gray_raster_render): Don't dereference
  2786. `target_map' if FT_RASTER_FLAG_DIRECT is set. Problem reported by
  2787. Stephan T. Lavavej <stl@nuwen.net>.
  2788. 2008-09-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2789. * src/otvalid/Jamfile: Add missing target `otvmath' for multi build
  2790. by jam.
  2791. * src/sfnt/Jamfile: Add missing target `ttmtx' for multi build by
  2792. jam.
  2793. 2008-09-20 Werner Lemberg <wl@gnu.org>
  2794. * src/smooth/ftgrays.c (gray_find_cell): Fix threshold. The values
  2795. passed to this function are already `normalized'. Problem reported
  2796. by Stephan T. Lavavej <stl@nuwen.net>.
  2797. * docs/CHANGES: Document it.
  2798. 2008-09-20 Werner Lemberg <wl@gnu.org>
  2799. * src/base/ftoutln.c: Include FT_INTERNAL_DEBUG_H.
  2800. (FT_Outline_Decompose): Decorate with tracing messages.
  2801. * src/smooth/ftgrays.c [DEBUG_GRAYS]: Replace with
  2802. FT_DEBUG_LEVEL_TRACE.
  2803. [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: Include stdio.h and
  2804. stdarg.h.
  2805. (FT_TRACE) [_STANDALONE_]: Remove.
  2806. (FT_Message) [_STANDALONE_ && FT_DEBUG_LEVEL_TRACE]: New function.
  2807. (FT_TRACE5, FT_TRACE7) [_STANDALONE_]: New macros.
  2808. (FT_ERROR) [_STANDALONE_]: Updated.
  2809. (gray_hline) [FT_DEBUG_LEVEL_TRACE]: Fix condition.
  2810. Use FT_TRACE7.
  2811. (gray_dump_cells): Make it `static void'.
  2812. (gray_convert_glyph): Use FT_TRACE7.
  2813. (FT_Outline_Decompose) [_STANDALONE_]: Synchronize with version in
  2814. ftoutln.c.
  2815. * src/base/ftadvanc.c (FT_Get_Advance, FT_Get_Advances): Use
  2816. FT_ERROR_BASE.
  2817. * docs/formats.txt: Updated.
  2818. 2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2819. * src/base/ftmac.c: Import sfnt-wrapped Type1 and sfnt-wrapped
  2820. CID-keyed font support.
  2821. * builds/mac/ftmac.c: Ditto.
  2822. 2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2823. * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Fix double free bug in
  2824. sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font support code.
  2825. `open_face_from_buffer' frees the passed buffer if it cannot open a
  2826. face from the buffer, so the caller must not free it.
  2827. 2008-09-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2828. * src/base/ftobjs.c (Mac_Read_sfnt_Resource): Add initial support
  2829. for sfnt-wrapped Type1 and sfnt-wrapped CID-keyed font.
  2830. (ft_lookup_PS_in_sfnt): New function to look up `TYP1' or `CID '
  2831. table in sfnt table directory. It is used before loading TrueType
  2832. font driver.
  2833. * docs/CHANGES: Add note about the current status of sfnt-wrapped
  2834. Type1 and sfnt-wrapped CID-keyed font support.
  2835. 2008-09-18 Werner Lemberg <wl@gnu.org>
  2836. * src/base/ftsystem.c (FT_Done_Memory): Use ft_sfree directly for
  2837. orthogonality (ft_free and ft_sfree could belong to different memory
  2838. pools). This fixes Savannah bug #24297.
  2839. 2008-09-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2840. * src/cff/cffobjs.c (cff_face_init): Use TTAG_OTTO defined
  2841. in ttags.h instead of numerical value 0x4F54544FL.
  2842. 2008-09-16 Werner Lemberg <wl@gnu.org>
  2843. * src/cff/cffgload.h, src/cff/cffgload.c
  2844. (cff_decoder_set_width_only): Eliminate function call.
  2845. 2008-09-15 George Williams <gww@silcom.com>
  2846. Fix Savannah bug #24179, reported by Bram Tassyns.
  2847. * src/type1/t1load.c (mm_axis_unmap, T1_Get_MM_Var): Fix computation
  2848. of default values.
  2849. 2008-09-15 Werner Lemberg <wl@gnu.org>
  2850. * src/tools/glnames.py (main): Surround `ft_get_adobe_glyph_index'
  2851. and `ft_adobe_glyph_list' with FT_CONFIG_OPTION_ADOBE_GLYPH_LIST to
  2852. prevent unconditional definition. This fixes Savannah bug #24241.
  2853. * src/psnames/pstables.h: Regenerated.
  2854. 2008-09-13 Werner Lemberg <wl@gnu.org>
  2855. * autogen.sh, builds/unix/configure.raw,
  2856. include/freetype/config/ftconfig.h, builds/unix/ftconfig.in: Minor
  2857. beautifying.
  2858. * include/freetype/ftadvanc.h, include/freetype/ftgasp.h,
  2859. include/freetype/ftlcdfil.h: Protect against FreeType 1.
  2860. Some other minor fixes.
  2861. * devel/ftoption.h: Synchronize with
  2862. include/freetype/config/ftoption.h.
  2863. 2008-09-11 Werner Lemberg <wl@gnu.org>
  2864. * src/base/ftbase.c: Include ftadvanc.c.
  2865. 2008-09-11 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2866. * builds/unix/ftconfig.in: Duplicate the cpp computation of
  2867. FT_SIZEOF_{INT|LONG} from include/freetype/config/ftconfig.h.
  2868. (FT_USE_AUTOCONF_SIZEOF_TYPES): New macro. If defined, the cpp
  2869. computation is disabled and the statically configured sizes are
  2870. used. This fixes Savannah bug #21250.
  2871. * builds/unix/configure.raw: Add the checks to compare the cpp
  2872. computation results of the bit length of int and long versus the
  2873. sizes detected by running `configure'. If the results are
  2874. different, FT_USE_AUTOCONF_SIZEOF_TYPES is defined to prioritize the
  2875. results.
  2876. New option --{enable|disable}-biarch-config is added to define or
  2877. undefine FT_USE_AUTOCONF_SIZEOF_TYPES manually.
  2878. 2008-09-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2879. * builds/unix/configure.raw: Clear FT2_EXTRA_LIBS when Carbon or
  2880. ApplicationService framework is missing. Although this value is not
  2881. used in building of FreeType2, it is written in `freetype2.pc' and
  2882. `freetype-config'.
  2883. 2008-09-01 david turner <david@freetype.org>
  2884. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Accept a negative cmap
  2885. index to mean `use default cached FT_Face's charmap'. This fixes
  2886. Savannah bug #22625.
  2887. * include/freetype/ftcache.h: Document it.
  2888. Make FT_MulFix an inlined function. This is done to speed up
  2889. FreeType a little (on x86 3% when loading+hinting, 10% when
  2890. rendering, ARM savings are more important though). Disable this by
  2891. undefining FT_CONFIG_OPTION_INLINE_MULFIX.
  2892. Use of assembler code can now be controlled with
  2893. FT_CONFIG_OPTION_NO_ASSEMBLER.
  2894. * include/freetype/config/ftconfig.h, builds/unix/ftconfig.in
  2895. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_arm): New assembler
  2896. implementation.
  2897. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MulFix_i386): Assembler
  2898. implementation taken from `ftcalc.c'.
  2899. [!FT_CONFIG_OPTION_NO_ASSEMBLER] (FT_MULFIX_ASSEMBLER): New macro
  2900. which is defined to the platform-specific assembler implementation
  2901. of FT_MulFix.
  2902. [FT_CONFIG_OPTION_INLINE_MULFIX && FT_MULFIX_ASSEMBLER]
  2903. (FT_MULFIX_INLINED): New macro.
  2904. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_NO_ASSEMBLER,
  2905. FT_CONFIG_OPTION_INLINE_MULFIX): New macros.
  2906. * include/freetype/freetype.h: Updated to handle FT_MULFIX_INLINED.
  2907. * src/base/ftcalc.c: Updated to use FT_MULFIX_ASSEMBLER and
  2908. FT_MULFIX_INLINED.
  2909. Add a new header named FT_ADVANCES_H declaring some new APIs to
  2910. extract the advances of one or more glyphs without necessarily
  2911. loading their outlines. Also provide `fast loaders' for the
  2912. TrueType, Type1, and CFF font drivers (more to come later).
  2913. * src/base/ftadvanc.c, include/freetype/ftadvanc.h: New files.
  2914. * include/freetype/config/ftheader.h (FT_ADVANCES_H): New macro.
  2915. * include/freetype/freetype.h (FT_LOAD_ADVANCE_ONLY): New macro.
  2916. * include/freetype/internal/ftdriver.h (FT_Face_GetAdvancesFunc):
  2917. `flags' and `advances' are now of type `FT_UInt' and `FT_Fixed',
  2918. respectively.
  2919. * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC): Add
  2920. ftadvanc.c.
  2921. * src/cff/cffdrivr.c (cff_get_advances): New function.
  2922. (cff_driver_class): Register it.
  2923. * src/cff/cffgload.c (cff_decoder_set_width_only): New function.
  2924. (cff_decoder_parse_charstrings): Handle `width_only'.
  2925. (cff_slot_load): Handle FT_LOAD_ADVANCE_ONLY.
  2926. * src/cff/cffgload.h (cff_decoder): New element `width_only'.
  2927. (cff_decoder_set_width_only): New declaration.
  2928. * src/truetype/ttdriver.c (tt_get_advances): New function.
  2929. (tt_driver_class): Register it.
  2930. * src/truetype/ttgload.c (Get_HMetrics, Get_VMetrics): Renamed to...
  2931. (TT_Get_HMetrics, TT_Get_VMetrics): This.
  2932. Update callers.
  2933. * src/truetype/ttgload.h: Declare them.
  2934. * src/type1/t1gload.h, src/type1/t1gload.c (T1_Get_Advances): New
  2935. function.
  2936. * src/type1/t1driver.c (t1_driver_class): Register T1_Get_Advances.
  2937. Add checks for minimum version of the `autotools' stuff.
  2938. * autogen.sh: Implement it.
  2939. (get_major_version, get_minor_version, get_patch_version,
  2940. compare_to_minimum_version, check_tool_version): New auxiliary
  2941. functions.
  2942. * README.CVS: Document it.
  2943. 2008-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2944. * src/sfnt/sfobjs.c (sfnt_open_font): Use TTAG_OTTO defined in
  2945. ttags.h instead of FT_MAKE_TAG( 'O', 'T', 'T', 'O' ).
  2946. 2008-08-28 Werner Lemberg <wl@gnu.org>
  2947. * src/type1/t1load.c (parse_encoding): Protect against infinite
  2948. loop. This fixes Savannah bug #24150 (where a patch has been posted
  2949. too).
  2950. 2008-08-23 Werner Lemberg <wl@gnu.org>
  2951. * src/type/t1afm.c (compare_kern_pairs), src/pxaux/afmparse.c
  2952. (afm_compare_kern_pairs): Fix comparison. This fixes Savannah bug
  2953. #24119.
  2954. 2008-08-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2955. * src/base/ftobjs.c (FT_Stream_New): Initialize *astream always,
  2956. even if passed library or arguments are invalid. This fixes a bug
  2957. that an uninitialized stream is freed when an invalid library handle
  2958. is passed. Originally proposed by Mike Fabian, 2008/08/18 on
  2959. freetype-devel.
  2960. (FT_Open_Face): Ditto (stream).
  2961. (load_face_in_embedded_rfork): Ditto (stream2).
  2962. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2963. * src/base/ftmac.c: Add a fallback to guess the availability of the
  2964. `ResourceIndex' type. It is used when built without configure
  2965. (e.g., a build with Jam).
  2966. * builds/mac/ftmac.c: Ditto.
  2967. * builds/unix/configure.raw: Set HAVE_TYPE_RESOURCE_INDEX to 1 or 0
  2968. explicitly, even if `ResourceIndex' is unavailable.
  2969. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2970. * builds/unix/configure.raw: In checking of Mac OS X features,
  2971. all-in-one header file `Carbon.h' is replaced by the minimum
  2972. header file `CoreServices.h', similar to current src/base/ftmac.c.
  2973. 2008-08-18 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  2974. * src/sfnt/ttcmap.c (tt_cmap2_validate): Skip the validation of
  2975. sub-header when its code_count is 0. Many Japanese Dynalab fonts
  2976. include such an empty sub-header (code_count == 0, first_code == 0
  2977. delta == 0, but offset != 0) as the second sub-header in SJIS cmap.
  2978. 2008-08-04 Werner Lemberg <wl@gnu.org>
  2979. * src/type1/t1tokens.h: Handle `ForceBold' keyword. This fixes
  2980. Savannah bug #23995.
  2981. * src/cid/cidload.c (parse_expansion_factor): New callback function.
  2982. (cid_field_records): Use it for `ExpansionFactor'.
  2983. * src/cod/cidtoken.h: Handle `ForceBold' keyword.
  2984. Don't handle `ExpansionFactor'.
  2985. 2008-08-04 Bram Tassyns <bramt@enfocus.be>
  2986. * src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which
  2987. resulted in incorrect scaling. This fixes Savannah bug #23973.
  2988. 2008-08-04 Werner Lemberg <wl@gnu.org>
  2989. Be more tolerant w.r.t. invalid entries in SFNT table directory.
  2990. * src/sfnt/ttload.c (check_table_dir): Ignore invalid entries and
  2991. adjust table count.
  2992. Add more trace messages.
  2993. (tt_face_load_font_dir): Updated.
  2994. 2008-07-30 Werner Lemberg <wl@gnu.org>
  2995. * src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
  2996. assume that the first argument on the stack is the bottom-most
  2997. element. Two reasons:
  2998. o According to people from Adobe it is missing in the Type 2
  2999. specification that pushing of additional, superfluous arguments
  3000. on the stack is prohibited.
  3001. o Acroread in general handles fonts differently, namely by popping
  3002. the number of arguments needed for a particular operand (as a PS
  3003. interpreter would do). In case of buggy fonts this causes a
  3004. different interpretation which of the elements on the stack are
  3005. superfluous and which not.
  3006. Since there are CFF subfonts (embedded in PDFs) which rely on
  3007. Acroread's behaviour, FreeType now does the same.
  3008. 2008-07-27 Werner Lemberg <wl@gnu.org>
  3009. Add extra mappings for `Tcommaaccent' and `tcommaaccent'. This
  3010. fixes Savannah bug #23940.
  3011. * src/psnames/psmodule.c (WGL_EXTRA_LIST_SIZE): Rename to...
  3012. (EXTRA_GLYPH_LIST_SIZE): This.
  3013. Increase by 2.
  3014. (ft_wgl_extra_unicodes): Rename to...
  3015. (ft_extra_glyph_unicodes): This.
  3016. Add two code values.
  3017. (ft_wgl_extra_glyph_names): Rename to...
  3018. (ft_extra_glyph_names): This.
  3019. Add two glyphs.
  3020. (ft_wgl_extra_glyph_name_offsets): Rename to...
  3021. (ft_extra_glyph_name_offsets): This.
  3022. Add two offsets.
  3023. (ps_check_wgl_name, ps_check_wgl_unicode): Rename to...
  3024. (ps_check_extra_glyph_name, ps_check_extra_glyph_unicode): This.
  3025. Updated.
  3026. (ps_unicodes_init): Updated.
  3027. 2008-07-26 Werner Lemberg <wl@gnu.org>
  3028. * src/cff/cffgload.c (cff_decoder_prepare,
  3029. cff_decoder_parse_charstrings): Improve debug output.
  3030. 2008-07-22 Martin McBride <mmcbride@emtex.com>
  3031. * src/sfnt/ttcmap.c (tt_cmap4_validate, tt_cmap4_char_map_linear,
  3032. tt_cmap4_char_map_binary): Handle fonts which treat the last segment
  3033. specially. According to the specification, such fonts would be
  3034. invalid but acroread accepts them.
  3035. 2008-07-16 Jon Foster <Jon.Foster@cabot.co.uk>
  3036. * src/pfr/pfrdrivr.c (pfr_get_advance): Fix off-by-one error.
  3037. * src/base/ftcalc.c (FT_MulFix): Fix portability issue.
  3038. * src/sfnt/ttpost.c (MAC_NAME) [!FT_CONFIG_OPTION_POSTSCRIPT_NAMES]:
  3039. Fix compiler warning.
  3040. 2008-07-16 Werner Lemberg <wl@gnu.org>
  3041. Handle CID-keyed fonts wrapped in an SFNT (with cmaps) correctly.
  3042. * src/cff/cffload.c (cff_font_load): Pass `pure_cff'.
  3043. Invert sids table only if `pure_cff' is set.
  3044. * src/cff/cffload.h: Udpated.
  3045. * src/cff/cffobjs.c (cff_face_init): Updated.
  3046. Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.
  3047. * docs/CHANGES: Updated.
  3048. 2008-07-09 Werner Lemberg <wl@gnu.org>
  3049. * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
  3050. where num_locations < num_glyphs. Problem reported by Ding Li.
  3051. 2008-07-05 Werner Lemberg <wl@gnu.org>
  3052. Since FreeType uses `$(value ...)', we now need GNU make 3.80 or
  3053. newer. This fixes Savannah bug #23648.
  3054. * configure: zsh doesn't like ${1+"$@"}.
  3055. Update needed GNU make version.
  3056. * builds/toplevel.mk: Check for `$(eval ...)'.
  3057. * docs/INSTALL.GNU, docs/INSTALL.CROSS, docs/INSTALL.UNIX: Document
  3058. it.
  3059. 2008-07-04 Werner Lemberg <wl@gnu.org>
  3060. * src/raster/ftraster.c (Draw_Sweep): If span is smaller than one
  3061. pixel, only check for dropouts if neither start nor end point lies
  3062. on a pixel center. This fixes Savannah bug #23762.
  3063. 2008-06-29 Werner Lemberg <wl@gnu.org>
  3064. * Version 2.3.7 released.
  3065. =========================
  3066. Tag sources with `VER-2-3-7'.
  3067. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
  3068. version number to 2.3.7.
  3069. * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
  3070. builds/win32/visualc/freetype.dsp,
  3071. builds/win32/visualc/freetype.vcproj,
  3072. builds/win32/visualce/index.html,
  3073. builds/win32/visualce/freetype.dsp,
  3074. builds/win32/visualce/freetype.vcproj: s/2.3.6/2.3.7/, s/236/237/.
  3075. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.
  3076. * builds/unix/configure.raw (version_info): Set to 9:18:3.
  3077. * docs/release: Updated.
  3078. 2008-06-28 Werner Lemberg <wl@gnu.org>
  3079. * src/ftglyph.c (FT_Matrix_Multiply, FT_Matrix_Invert): Move to...
  3080. * src/ftcalc.c: Here. This fixes Savannah bug #23729.
  3081. 2008-06-27 Werner Lemberg <wl@gnu.org>
  3082. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
  3083. Horizontal_Gray_Sweep_Drop): Test for intersections which
  3084. degenerate to a single point can be ignored; this has been confirmed
  3085. by Greg Hitchcock from Microsoft. (This was commented out code.)
  3086. 2008-06-26 Werner Lemberg <wl@gnu.org>
  3087. Improve navigation in API reference.
  3088. * src/tools/docmaker/tohtml.py (html_header_3): Renamed to...
  3089. (html_header_6): This.
  3090. (html_header_3, html_header_3i, html_header_4, html_header_5,
  3091. html_header_5t): New strings.
  3092. (toc_footer_start, toc_footer_end): New strings.
  3093. (HtmlFormatter::html_header): Updated.
  3094. (HtmlFormatter::html_index_header, HtmlFormatter::html_toc_header):
  3095. New strings.
  3096. (HtmlFormatter::index_enter): Use `html_index_header'.
  3097. (HtmlFormatter::index_exit): Print `html_footer'.
  3098. (HtmlFormatter::toc_enter): Use `html_toc_header'.
  3099. (HtmlFormatter::toc_exit): Print proper footer.
  3100. Convert ~ to non-breakable space.
  3101. * src/tools/docmaker/tohtml.py (make_html_para): Implement it.
  3102. Update header files accordingly.
  3103. 2008-06-24 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3104. * builds/unix/configure.raw: Check type `ResourceIndex' explicitly
  3105. and define HAVE_TYPE_RESOURCE_INDEX if it is defined. Mac OS X 10.5
  3106. bundles 10.4u SDK with MAC_OS_X_VERSION_10_5 macro but without
  3107. ResourceIndex type definition. The macro does not inform the type
  3108. availability.
  3109. * src/base/ftmac.c: More parentheses are inserted to clarify the
  3110. conditionals to disable legacy APIs in `10.5 and later' cases. If
  3111. HAVE_TYPE_RESOURCE_INDEX is not defined, ResourceIndex is defined.
  3112. 2008-06-24 Werner Lemberg <wl@gnu.org>
  3113. * src/truetype/ttinterp.c (Ins_SCANTYPE): Don't check rendering
  3114. mode.
  3115. * src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
  3116. Draw_Sweep): No-dropout mode is value 2, not value 0.
  3117. (Draw_Sweep): Really skip dropout handling for no-dropout mode.
  3118. 2008-06-24 Werner Lemberg <wl@gnu.org>
  3119. * src/psaux/psobjs.c (t1_builder_close_contour): Don't add contour
  3120. if it consists of one point only. Based on a patch from Savannah
  3121. bug #23683 (from John Tytgat).
  3122. 2008-06-22 Werner Lemberg <wl@gnu.org>
  3123. * src/truetype/ttgload.c (TT_Load_Glyph): Protect bytecode stuff
  3124. with IS_HINTED.
  3125. * docs/CHANGES: Updated.
  3126. 2008-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3127. * builds/unix/configure.raw: If CFLAGS has `-isysroot XXX' option
  3128. but LDFLAGS does not, import it to LDFLAGS. The option is used to
  3129. specify non-default SDK on Mac OS X (e.g., universal binary SDK for
  3130. Mac OS X 10.4 on PowerPC platform). Although Apple TechNote 2137
  3131. recommends to add the option only to CFLAGS, LDFLAGS should include
  3132. it because libfreetype.la is built with -no-undefined. This fixes a
  3133. bug reported by Ryan Schmidt in MacPorts,
  3134. http://trac.macports.org/ticket/15331.
  3135. 2008-06-21 Werner Lemberg <wl@gnu.org>
  3136. Enable access to the various dropout rules of the B&W rasterizer.
  3137. Pass dropout rules from the TT bytecode interpreter to the
  3138. rasterizer.
  3139. * include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
  3140. FT_OUTLINE_EXCLUDE_STUBS): New flags for FT_Outline.
  3141. * src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
  3142. Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
  3143. OpenType specification.
  3144. Fix mode 4 computation.
  3145. (Render_Glyph, Render_Gray_Glyph): Handle new outline flags.
  3146. * src/truetype/ttgload.c (TT_Load_Glyph) Convert scan conversion
  3147. mode to FT_OUTLINE_XXX flags.
  3148. * src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.
  3149. 2008-06-19 Werner Lemberg <wl@gnu.org>
  3150. * src/cff/cffobjs.c (cff_face_init): Compute final
  3151. `dict->units_per_em' value before assigning it to
  3152. `cffface->units_per_EM'. Otherwise, CFFs without subfonts are
  3153. scaled incorrectly if the font matrix is non-standard. This fixes
  3154. Savannah bug #23630.
  3155. * docs/CHANGES: Updated.
  3156. 2008-06-19 Werner Lemberg <wl@gnu.org>
  3157. * src/type/t1objs.c (T1_Face_Init): Slightly improve algorithm fix
  3158. from 2008-06-19.
  3159. 2008-06-18 Werner Lemberg <wl@gnu.org>
  3160. * src/type/t1objs.c (T1_Face_Init): Fix change from 2008-03-21.
  3161. Reported by Peter Weilbacher <mozilla@weilbacher.org>.
  3162. * docs/CHANGES: Updated.
  3163. 2008-06-15 George Williams <gww@silcom.com>
  3164. * src/otvalid/otvgpos.c (otv_MarkBasePos_validate): Set
  3165. `valid->extra2' to 1. This is undocumented in the OpenType 1.5
  3166. specification.
  3167. 2008-06-15 Werner Lemberg <wl@gnu.org>
  3168. * src/base/ftcalc.c (FT_MulFix) <asm>: Protect registers correctly
  3169. from clobbering. Patch from Savannah bug report #23556.
  3170. * docs/CHANGES: Document it.
  3171. 2008-06-10 Werner Lemberg <wl@gnu.org>
  3172. * autogen.sh: Add option `--install' to libtoolize.
  3173. 2008-06-10 Werner Lemberg <wl@gnu.org>
  3174. * Version 2.3.6 released.
  3175. =========================
  3176. Tag sources with `VER-2-3-6'.
  3177. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump
  3178. version number to 2.3.6.
  3179. * README, Jamfile (RefDoc), builds/win32/visualc/index.html,
  3180. builds/win32/visualc/freetype.dsp,
  3181. builds/win32/visualc/freetype.vcproj,
  3182. builds/win32/visualce/index.html,
  3183. builds/win32/visualce/freetype.dsp,
  3184. builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/.
  3185. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6.
  3186. * builds/unix/configure.raw (version_info): Set to 9:17:3.
  3187. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x'
  3188. and `scale_y'.
  3189. * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'.
  3190. * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H.
  3191. * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.
  3192. 2008-06-10 Werner Lemberg <wl@gnu.org>
  3193. * src/base/ftobjs.c (open_face): Check `clazz->init_face' and
  3194. `clazz->done_face'.
  3195. 2008-06-09 VaDiM <s_sliva@rambler.ru>
  3196. Support debugging on WinCE. From Savannah patch #6536; this fixes
  3197. bug #23497.
  3198. * builds/win32/ftdebug.c (OutputDebugStringEx): New function/macro
  3199. as a replacement for OutputDebugStringA (which WinCE doesn't have).
  3200. Update all callers.
  3201. (ft_debug_init) [_WIN32_CE]: WinCE apparently doesn't have
  3202. environment variables.
  3203. 2008-06-09 Werner Lemberg <wl@gnu.org>
  3204. * README.CVS: Updated.
  3205. * builds/unix/configure.raw, builds/unix/freetype-config.in: Updated
  3206. for newer versions of autoconf and friends.
  3207. 2008-06-08 Werner Lemberg <wl@gnu.org>
  3208. * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
  3209. `private_len' unsigned.
  3210. * src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
  3211. it as such.
  3212. (T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.
  3213. * src/base/ftstream.c (FT_Stream_Skip): Reject negative values.

  3218. * src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
  3219. `last_point'.
  3220. * src/sfnt/ttload.c (tt_face_load_max_profile): Limit
  3221. `maxTwilightPoints'.
  3222. 2008-06-06 Werner Lemberg <wl@gnu.org>
  3223. * src/truetype/ttinterp.c (Ins_IP): Handle case `org_dist == 0'
  3224. correctly. This fixes glyphs `t' and `h' of Arial Narrow at 12ppem.
  3225. 2008-06-03 Werner Lemberg <wl@gnu.org>
  3226. * include/freetype/ftcache.h (FTC_FaceID): Change type back to
  3227. FT_Pointer. Reported by Ian Britten <britten@caris.com>.
  3228. 2008-06-02 Werner Lemberg <wl@gnu.org>
  3229. Emit header info for defined FreeType objects in reference.
  3230. * src/tools/docmaker/content.py (re_header_macro): New regexp.
  3231. (ContentProcessor::__init__): Initialize new dictionary `headers'.
  3232. (DocBlock::__init__): Collect macro header definitions.
  3233. * src/tools/docmaker/tohtml.py (header_location_header,
  3234. header_location_footer): New strings.
  3235. (HtmlFormatter::__init__): Pass `headers' dictionary.
  3236. (HtmlFormatter::print_html_field): Don't emit paragraph tags.

  3239. 2008-06-01 Werner Lemberg <wl@gnu.org>
  3240. * include/freetype/config/ftheader.h (FT_UNPATENTED_HINTING_H,
  3241. FT_INCREMENTAL_H): Added.
  3242. 2008-05-28 Werner Lemberg <wl@gnu.org>
  3243. * src/tools/docmaker/sources.py (SourceBlock::__init__): While
  3244. looking for markup tags, return immediately as soon a single one is
  3245. found.
  3246. 2008-05-28 Werner Lemberg <wl@gnu.org>
  3247. * src/truetype/ttinterp.c (Ins_MD): The MD instruction also uses
  3248. original, unscaled input values. Confirmed by Greg Hitchcock from
  3249. Microsoft.
  3250. 2008-05-27 Werner Lemberg <wl@gnu.org>
  3251. * src/tools/docmaker/tohtml.py (block_footer_start,
  3252. block_footer_middle): Beautify output.
  3253. 2008-05-25 Werner Lemberg <wl@gnu.org>
  3254. * src/raster/ftraster.c (fc_black_render): Return 0 when we are
  3255. trying to render into a zero-width/height bitmap, not an error code.
  3256. * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
  3257. of the graphics state for subglyphs to...
  3258. (TT_Hint_Glyph): This function.
  3259. Hinting instructions for a composite glyph apparently refer to the
  3260. just hinted subglyphs, not the unhinted, unscaled outline. This
  3261. seems to fix Savannah bugs #20973 and (at least partially) #23310.
  3262. 2008-05-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3263. * src/base/ftmac.c (FT_New_Face_From_Suitcase): Check if valid
  3264. `aface' is returned by FT_New_Face_From_FOND(). The patch was
  3265. proposed by an anonymous reporter of Savannah bug #23204.
  3266. 2008-05-18 Werner Lemberg <wl@gnu.org>
  3267. * src/pshinter/pshalgo.c (ps_hints_apply): Reset scale values after
  3268. correction for pixel boundary. Without this patch, the effect can
  3269. be cumulative under certain circumstances, making glyphs taller and
  3270. taller after each call. This fixes Savannah bug #19976.
  3271. 2008-05-18 Werner Lemberg <wl@gnu.org>
  3272. * src/base/ftdebug.c (FT_Message, FT_Panic): Send output to stderr.
  3273. This fixes Savannah bug #23280.
  3274. * docs/CHANGES: Updated.
  3275. 2008-05-18 David Turner <david@freetype.org>
  3276. * src/psnames/psmodule.c (ft_wgl_extra_unicodes,
  3277. ft_wgl_extra_glyph_names, ft_wgl_extra_glyph_name_offsets,
  3278. ps_check_wgl_name, ps_check_wgl_unicode): Use `static' to make
  3279. declarations non-global.
  3280. * src/type1/t1load.c: Add missing comment.
  3281. 2008-05-17 Sam Hocevar <samh>
  3282. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Handle zero-contour
  3283. glyphs correctly. Patch from Savannah bug #23277.
  3284. 2008-05-16 Werner Lemberg <wl@gnu.org>
  3285. * docs/CHANGES: Updated.
  3286. 2008-05-16 Sergey Tolstov <stolstov@esri.com>

  3290. ft_wgl_extra_glyph_name_offsets): New arrays.
  3291. (ps_check_wgl_name, ps_check_wgl_unicode): New functions.
  3292. (ps_unicodes_init): Use them to add additional Unicode mappings.
  3293. 2008-05-15 Werner Lemberg <wl@gnu.org>
  3294. * src/psaux/t1decode.c (t1_decoder_parse_charstrings)
  3295. <op_closepath>: `closepath' without a path is a no-op, not an error
  3296. (cf. the PS reference manual).
  3297. Reported by Martin McBride.
  3298. 2008-05-15 Werner Lemberg <wl@gnu.org>
  3299. * builds/toplevel.mk (CONFIG_GUESS, CONFIG_SUB): Updated.
  3300. 2008-05-15 Werner Lemberg <wl@gnu.org>
  3301. * src/type1/t1load.c (parse_subrs): Accept fonts with a subrs array
  3302. which contains a single but empty entry. This is technically
  3303. invalid (since it must end with `return'), but...
  3304. Reported by Martin McBride.
  3305. 2008-05-14 Werner Lemberg <wl@gnu.org>
  3306. Finish fix of scaling bug of CID-keyed CFF subfonts.
  3307. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c
  3308. (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New
  3309. functions.
  3310. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to
  3311. provide global hinting data for both the top-font and all subfonts
  3312. (with proper scaling).
  3313. * src/cff/cffobjs.c (cff_make_private_dict): New function, using
  3314. code from `cff_size_init'.
  3315. (cff_size_init, cff_size_done, cff_size_select, cff_size_request):
  3316. Use CFF_Internal and handle subfonts.
  3317. (cff_face_init): Handle top-dict and subfont matrices correctly;
  3318. apply some heuristic in case of unlikely matrix concatenation
  3319. results. This has been discussed with people from Adobe (thanks
  3320. goes mainly to David Lemon) who confirm that the CFF specs are fuzzy
  3321. and not correct.
  3322. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument.
  3323. * src/cff/cffgload.c (cff_builder_init): Updated.
  3324. (cff_decoder_prepare): Handle hints globals for subfonts.
  3325. Update all callers.
  3326. (cff_slot_load): Handling scaling of subfonts properly.
  3327. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.

  3335. * docs/CHANGES: Document it.
  3336. 2008-05-04 Werner Lemberg <wl@gnu.org>
  3337. First steps to fix the scaling bug of CID-keyed CFF subfonts,
  3338. reported by Ding Li on 2008/03/28 on freetype-devel.
  3339. * src/base/cff/cffparse.c (power_tens): New array.
  3340. (cff_parse_real): Rewritten to introduce a fourth parameter which
  3341. returns the `scaling' of the real number so that we have no
  3342. precision loss. This is not used yet.
  3343. Update all callers.
  3344. (cff_parse_fixed_thousand): Replace with...
  3345. (cff_parse_fixed_scaled): This function. Update all callers.
  3346. 2008-05-03 Werner Lemberg <wl@gnu.org>
  3347. * src/base/ftobjs.c (FT_Load_Glyph): Call the auto-hinter without
  3348. transformation since it recursively calls FT_Load_Glyph. This fixes
  3349. Savannah bug #23143.
  3350. 2008-04-26 Werner Lemberg <wl@gnu.org>
  3351. * include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x'
  3352. and `scale_y' as obsolete since they aren't used.
  3353. * src/psaux/psobjs.c (t1_builder_init): Updated.
  3354. * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as
  3355. obsolete since they aren't used.
  3356. * src/cff/cffgload.c (cff_builder_init): Updated.
  3357. 2008-04-14 Werner Lemberg <wl@gnu.org>
  3358. * src/pcf/pcfdrivr.c (PCF_Face_Init): Protect call to
  3359. `FT_Stream_OpenLZW' with `FT_CONFIG_OPTION_USE_LZ'. From Savannah
  3360. bug #22909.
  3361. 2008-04-13 Werner Lemberg <wl@gnu.org>
  3362. * src/psaux/psconv.c (PS_Conv_ToFixed): Increase precision if
  3363. integer part is zero.
  3364. 2008-04-01 Werner Lemberg <wl@gnu.org>
  3365. Fix compilation with g++ 4.1 (with both `single' and `multi'
  3366. targets).
  3367. * src/base/ftobjs.c (FT_Open_Face): Don't define a variable in block
  3368. which is crossed by a `goto'.
  3369. * src/otvalid/otvalid.h (otv_MATH_validate): Add prototype.
  3370. 2008-03-31 Werner Lemberg <wl@gnu.org>
  3371. Fix support for subsetted CID-keyed CFFs.
  3372. * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED,
  3373. FT_IS_CID_KEYED): New macros.
  3374. * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the
  3375. maximum CID value in CID-keyed CFFs.
  3376. Handle FT_FACE_FLAG_CID_KEYED flag.
  3377. * docs/CHANGES: Document it.
  3378. Fix CFF font matrix calculation and improve precision.
  3379. * src/cff/cffparse.c (cff_parse_real): Increase precision if integer
  3380. part is zero.
  3381. (cff_parse_font_matrix): Simplify computation of `units_per_em';
  3382. this prevents overflow also.
  3383. Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts.
  3384. * src/cid/cidriver.c: Include FT_SERVICE_CID_H.
  3385. (cid_get_ros): New function.
  3386. (cid_service_cid_info): New service structure.
  3387. (cid_services): Register it.
  3388. 2008-03-23 Werner Lemberg <wl@gnu.org>
  3389. Adjustments for Visual C++ 8.0, as reported by Rainer Deyke.
  3390. * builds/compiler/visualc.mk (CFLAGS): Remove /W5.
  3391. (ANSIFLAGS): Add _CRT_SECURE_NO_DEPRECATE.
  3392. 2008-03-21 Laurence Darby <ldarby>
  3393. * src/type1/t1objs.c (T1_Face_Init): Use `/Weight'. Patch from
  3394. Savannah bug #22675.
  3395. 2008-03-13 Derek Clegg <dclegg@apple.com>
  3396. * src/truetype/ttgxvar.c (TT_Get_MM_Var): Fix named style loop.
  3397. Patch from Savannah bug #22541.
  3398. 2008-03-03 Masatoshi Kimura <VYV03354@nifty.ne.jp>
  3399. * src/sfnt/ttcmap.c (tt_cmap14_char_map_nondef_binary,
  3400. tt_cmap14_find_variant): Return correct value.
  3401. (tt_cmap14_variant_chars): Fix check for `di'.
  3402. 2008-02-29 Wermer Lemberg <wl@gnu.org>
  3403. * docs/CHANGES: Updated.
  3404. 2008-02-29 Wolf
  3405. Add build support for symbian platform. From Savannah bug #22440.
  3406. * builds/symbian/*: New files.
  3407. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3408. * src/base/ftmac.c (parse_fond): Fix a bug of PostScript font name
  3409. synthesis. For any face of a specified FOND, always the name for
  3410. the first face was used. Except of a FOND that refers multiple
  3411. Type1 font files, wrong synthesized font names are not used at all,
  3412. so this is an invisible bug. A few limit checks are added too.
  3413. * builds/mac/ftmac.c: Ditto.
  3414. 2008-02-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3415. * builds/unix/configure.raw: Split compiler option to link Carbon
  3416. frameworks to one option for CoreServices framework and another
  3417. option for ApplicationServices framework. The split options can be
  3418. managed by GNU libtool to avoid unrequired duplication when FreeType
  3419. is linked with other applications. Suggested by Daniel Macks,
  3420. Savannah bug #22366.
  3421. 2008-02-18 Victor Stinner <victor.stinner@haypocalc.com>
  3422. * src/truetype/ttinterp.c (Ins_IUP): Check number of points. Fix
  3423. from Savannah bug #22356.
  3424. 2008-02-17 Jonathan Blow <jon@number-none.com>
  3425. * src/autofit/afloader.c (af_loader_load_g, af_loader_load_glyph):
  3426. Check for valid callback pointers.
  3427. 2008-02-15 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3428. * src/base/ftmac.c (FT_New_Face_From_SFNT): Check the sfnt resource
  3429. handle by its value instead of ResError(), fix provided by Deron
  3430. Kazmaier. According to the Resource Manager Reference,
  3431. GetResource(), Get1Resource(), GetNamedResource(),
  3432. Get1NamedResource() and RGetResource() set noErr but return NULL
  3433. handle when they can not find the requested resource. These
  3434. functions never return undefined values, so it is sufficient to
  3435. check if the handle is not NULL.
  3436. * builds/mac/ftmac.c (FT_New_Face_From_SFNT): Ditto.
  3437. 2008-02-14 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3438. * src/base/ftbase.c: <ftmac.c> is replaced by "ftmac.c" as other
  3439. inclusion styles. Now it always includes src/base/ftmac.c;
  3440. builds/mac/ftmac.c is never included in any configuration.
  3441. * builds/unix/configure.raw: Print warning if configure is executed
  3442. with options to specify Carbon functionalities explicitly.
  3443. * docs/INSTALL.MAC: Note that legacy builds/mac/ftmac.c is not
  3444. included automatically and manual replacement is required.
  3445. 2008-02-11 Werner Lemberg <wl@gnu.org>
  3446. * builds/modules.mk (CLOSE_MODULE, REMOVE_MODULE), builds/detect.mk
  3447. (dos_setup), builds/freetype.mk (clean_project_dos,
  3448. distclean_project_dos): Don't use \ but $(SEP). Reported by Duncan
  3449. Murdoch.
  3450. 2008-01-18 Sylvain Pasche <sylvain.pasche@gmail.com>
  3451. * src/base/ftlcdfil.c (_ft_lcd_filter_legacy): Updated comment to
  3452. mention intra-pixel algorithm.
  3453. * include/freetype/freetype.h (FT_Render_Mode): Mention that
  3454. FT_Library_SetLcdFilter can be used to reduce fringes.
  3455. 2008-01-16 Werner Lemberg <wl@gnu.org>
  3456. * src/raster/ftraster.c (ft_black_render): Check `outline' before
  3457. using it. Reported by Allan Yang.
  3458. 2008-01-12 Werner Lemberg <wl@gnu.org>
  3459. * src/raster/ftraster.c (FT_CONFIG_OPTION_5_GRAY_LEVELS): Remove.
  3460. 2008-01-12 Allan Yang, Jian Hua - SH <Allan.Yang@fmc.fujitsu.com>
  3461. * src/raster/ftraster.c (ft_black_init)
  3462. [FT_RASTER_OPTION_ANTI_ALIASING]: Fix compilation.
  3463. 2008-01-10 Werner Lemberg <wl@gnu.org>
  3464. * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
  3465. where the number of contours in a simple glyph is zero (and which
  3466. does contain an entry in the `glyf' table). This fixes Savannah bug
  3467. #21990.
  3468. 2008-01-04 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3469. Formatting suggested by Sean McBride.
  3470. * builds/mac/ftmac.c: Formatting (tab expanded).
  3471. * src/autofit/afindic.c: Ditto.
  3472. * src/base/ftcid.c: Ditto.
  3473. * src/base/ftmac.c: Ditto.
  3474. 2007-12-30 Werner Lemberg <wl@gnu.org>
  3475. * src/smooth/ftgrays.c (gray_raster_render): Check `outline'
  3476. correctly.
  3477. 2007-12-21 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3478. Improvement of POSIX resource-fork accessor to load unsorted
  3479. references in a resource. In HelveLTMM (resource-fork PostScript
  3480. Type1 font bundled with Mac OS X since 10.3.x), the appearance order
  3481. of PFB chunks is not sorted; sorting the chunks by reference IDs is
  3482. required.
  3483. * include/freetype/internal/ftrfork.h (FT_RFork_Ref): New structure
  3484. type to store a pair of reference ID and offset to the chunk.
  3485. * src/base/ftrfork.c (ft_raccess_sort_ref_by_id): New function to
  3486. sort FT_RFork_Ref by their reference IDs.
  3487. (FT_Raccess_Get_DataOffsets): Returns an array of offsets that is
  3488. sorted by reference ID.
  3489. 2007-12-14 Werner Lemberg <wl@gnu.org>
  3490. * src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten'
  3491. division too early; otherwise the most significant digit(s) of the
  3492. final result are lost as the value is truncated to an integer. This
  3493. fixes Savannah bug #21794 (where the patch has been posted too).
  3494. 2007-12-06 Fix <4d876b82@gmail.com>
  3495. Pass options from one configure script to another as-is (not
  3496. expanded). This is needed for options like
  3497. --includedir='${prefix}/include'.
  3498. * builds/unix/detect.mk, configure: Prevent argument expansion in
  3499. call to the (real) `configure' script.
  3500. 2007-12-06 Werner Lemberg <wl@gnu.org>
  3501. * src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
  3502. TT_USE_BYTECODE_INTERPRETER isn't defined.
  3503. 2007-12-06 Werner Lemberg <wl@gnu.org>
  3504. There exist CFFs which contain opcodes for the Type 1 operators
  3505. `hsbw' and `closepath' which are both invalid in Type 2 charstrings.
  3506. However, it doesn't harm to support them.
  3507. * src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
  3508. `cff_op_closepath.'
  3509. (cff_argument_counts): Ditto.
  3510. (cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
  3511. and 13 (hsbw) which are invalid in Type 2 charstrings.
  3512. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3513. * src/base/ftrfork.c (raccess_guess_darwin_newvfs): New function to
  3514. support new pathname syntax `..namedfork/rsrc' to access a resource
  3515. fork on Mac OS X. The legacy syntax `/rsrc' does not work on
  3516. case-sensitive HFS+.
  3517. (raccess_guess_darwin_hfsplus): Fix a bug in the calculation of
  3518. buffer size to store a pathname.
  3519. * include/freetype/internal/ftrfork.h: Increment the number of
  3520. resource fork guessing rule.
  3521. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3522. * builds/unix/configure.raw: Improve the compile tests to search
  3523. Carbon functions.
  3524. * builds/mac/ftmac.c: Import fixes for Carbon incompatibilities
  3525. proposed by Sean McBride from src/base/ftmac.c (see 2007-11-16).
  3526. 2007-12-06 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3527. The documents and comments for Mac OS X are improved by Sean
  3528. McBride.
  3529. * src/base/ftmac.c: Fix a comment.
  3530. * include/freetype/ftmac.h: Ditto.
  3531. * docs/INSTALL.MAC: Improve English and add comment on lowest
  3532. system version specified by MACOSX_DEPLOYMENT_TARGET.
  3533. 2007-12-04 Werner Lemberg <wl@gnu.org>
  3534. * src/cff/cffload.c (cff_subfont_load): Don't use logical OR to
  3535. concatenate error codes.
  3536. * src/sfnt/ttsbit.c (Load_SBit_Range): Ditto.
  3537. 2007-12-04 Graham Asher <graham.asher@btinternet.com>
  3538. * src/truetype/ttobjs.c (tt_face_init): Don't use logical OR to
  3539. concatenate error codes.
  3540. 2007-12-04 Sean McBride <sean@rogue-research.com>
  3541. * src/pfr/pfrgload.c (pfr_glyph_load_compound): Remove compiler
  3542. warning.
  3543. 2007-11-20 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3544. Fix MacOS legacy font support by Masatake Yamato on Mac OS X. It is
  3545. not working since 2.3.5. In FT_Open_New(), if FT_New_Stream()
  3546. cannot mmap() the specified file and cannot seek to head of the
  3547. specified file, it returns NULL stream and FT_Open_New() returns the
  3548. error immediately. On MacOS, most legacy MacOS fonts fall into such
  3549. a scenario because their data forks are zero-sized and cannot be
  3550. sought. To proceed to guessing of resource fork fonts, the
  3551. functions for legacy MacOS font must properly handle the NULL stream
  3552. returned by FT_New_Stream().
  3553. * src/base/ftobjs.c (IsMacBinary): Return error
  3554. FT_Err_Invalid_Stream_Operation immediately when NULL stream is
  3555. passed.
  3556. (FT_Open_Face): Even when FT_New_Stream() returns an error, proceed
  3557. to fallback. Originally, legacy MacOS font is tested in the cases
  3558. of FT_Err_Invalid_Stream_Operation (occurs when data fork is empty)
  3559. or FT_Err_Unknown_File_Format (occurs when AppleSingle header or
  3560. .dfont header is combined). Now the case of
  3561. FT_Err_Cannot_Open_Stream is included.
  3562. * src/base/ftrfork.c (FT_Raccess_Guess): When passed stream is NULL,
  3563. skip FT_Stream_Seek(), which seeks to the head of stream, and
  3564. proceed to unit testing of raccess_guess_XXX(). FT_Stream_Seek()
  3565. for a NULL stream causes a Bus error on Mac OS X.
  3566. (raccess_guess_apple_double): Return FT_Err_Cannot_Open_Stream
  3567. immediately if passed stream is NULL.
  3568. (raccess_guess_apple_single): Ditto.
  3569. 2007-11-16 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3570. Fix for Carbon incompatibilities since Mac OS X 10.5,
  3571. proposed by Sean McBride.
  3572. * doc/INSTALL.MAC: Comment on MACOSX_DEPLOYMENT_TARGET.
  3573. * include/freetype/ftmac.h: Deprecate FT_New_Face_From_FOND and
  3574. FT_GetFilePath_From_Mac_ATS_Name. Since Mac OS X 10.5, calling
  3575. Carbon functions from a forked process is classified as unsafe
  3576. by Apple. All Carbon-dependent functions should be deprecated.
  3577. * src/base/ftmac.c: Use essential header files
  3578. <CoreServices/CoreServices.h> and
  3579. <ApplicationServices/ApplicationServices.h> instead of
  3580. all-in-one header file <Carbon/Carbon.h>.
  3581. Include <sys/syslimits.h> and replace HFS_MAXPATHLEN by Apple
  3582. genuine macro PATH_MAX.
  3583. Add fallback macro for kATSOptionFlagsUnRestrictedScope which
  3584. is not found in Mac OS X 10.0.
  3585. Multi-character constants ('POST', 'sfnt' etc) are replaced by
  3586. 64bit constants calculated by FT_MAKE_TAG() macro.
  3587. For the index in the segment of resource fork, new portable
  3588. type ResourceIndex is introduced for better compatibility.
  3589. This type is since Mac OS X 10.5, so it is defined as short
  3590. when built on older platforms.
  3591. (FT_ATSFontGetFileReference): If build target is only the systems
  3592. 10.5 and newer, it calls Apple genuine ATSFontGetFileReference().
  3593. (FT_GetFile_From_Mac_ATS_Name): Return an error if system is 10.5
  3594. and newer or 64bit platform, because legacy type FSSpec type is
  3595. removed completely.
  3596. (FT_New_Face_From_FSSpec): Ditto.
  3597. 2007-11-01 Werner Lemberg <wl@gnu.org>
  3598. * src/sfnt/sfobjs.c (sfnt_done_face): Check `sfnt' everywhere. This
  3599. fixes Savannah bug #21485.
  3600. 2007-10-29 Daniel Svoboda <dasvo@planeta@cz>
  3601. * src/winfonts/winfnt.c (FNT_Face_Init): Check first that the driver
  3602. can handle the font at all, then check `face_index'. Otherwise, the
  3603. driver might return the wrong error code. This fixes Savannah bug
  3604. #21468.
  3605. 2007-10-21 Werner Lemberg <wl@gnu.org>
  3606. * src/sfnt/sfobjs.c (sfnt_load_face): Support bit 9 and prepare
  3607. support for bit 8 of the `fsSelection' field in the `OS/2' table.
  3608. MS is already using this; hopefully, this becomes part of OpenType
  3609. 1.5.
  3610. Prepare also support for `name' IDs 21 (WWS_FAMILY) and 22
  3611. (WWS_SUBFAMILY).
  3612. 2007-10-20 Werner Lemberg <wl@gnu.org>
  3613. * src/tools/docmaker/tohtml.py (html_header_2): Fix typo.
  3614. Add `td.left' element to CSS.
  3615. (toc_section_enter): Use it.
  3616. 2007-10-18 David Turner <david@freetype.org>
  3617. * include/freetype/freetype.h, src/base/ftobjs.c: Rename API
  3618. functions related to cmap type 14 support to the
  3619. `FT_Object_ActionName' scheme:
  3620. FT_Get_Char_Variant_index -> FT_Face_GetCharVariantIndex
  3621. FT_Get_Char_Variant_IsDefault -> FT_Face_GetCharVariantIsDefault
  3622. FT_Get_Variant_Selectors -> FT_Face_GetVariantSelectors
  3623. FT_Get_Variants_Of_Char -> FT_Face_GetVariantsOfChar
  3624. FT_Get_Chars_Of_Variant -> FT_Face_GetCharsOfVariant
  3625. Update documentation accordingly.
  3626. * src/sfnt/ttcmap.c: Stronger cmap 14 validation.
  3627. Make the code a little more consistent with FreeType coding
  3628. conventions and modify the cmap14 functions that returned a newly
  3629. allocated array to use a persistent vector from the TT_CMap14 object
  3630. instead.
  3631. (TT_CMap14Rec): Provide array and auxiliary data for result.
  3632. (tt_cmap14_done, tt_cmap14_ensure): New functions.
  3633. (tt_cmap14_init, tt_cmap14_validate, tt_cmap14_char_map_def_binary,

  3674. 2007-10-01 Werner Lemberg <wl@gnu.org>
  3675. * src/base/ftobjs.c (find_unicode_charmap): If search for a UCS-4
  3676. charmap fails, do the loop again while searching a UCS-2 charmap.
  3677. This favours MS charmaps over Apple ones.
  3678. 2007-08-29 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  3679. * src/base/ftmac.c: Introduction of abstract `short' data types,
  3680. ResFileRefNum and ResID. These types were introduced for Copland,
  3681. then backported to MPW. The variables exchanged with FileManager
  3682. QuickDraw frameworks are redefined by these data types. Patch was
  3683. proposed by Sean McBride.
  3684. * builds/mac/ftmac.c: Ditto.

  4206. same as the other value.
  4207. 2007-04-02 David Turner <david@freetype.org>
  4208. Add special code to detect `extra-light' fonts and do not snap their
  4209. stem widths too much to avoid bizarre hinting effects.
  4210. * src/autofit/aflatin.h (AF_LatinAxisRec): Add `standard_width' and
  4211. `extra_light' members.
  4212. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Initialize

  4221. gracefully.
  4222. (_bdf_set_default_spacing): Increase `name' buffer size to 256 and

  4235. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
  4236. computations in order to ignore single-point contours. These are

  4238. points that are very far from the glyph's real outline, ruining the
  4239. computation.
  4240. * src/autofit/afloader.c (af_loader_load_g): In the case of
  4241. monospaced fonts, always set `rsb_delta' and `lsb_delta' to 0.

  4263. * builds/unix/configure.raw: Dequote `OS_INLINE' in comment of

  4376. (FT_New_Face_From_FSRef): Deprecated, using FSRef.
  4377. * src/base/ftmac.c: Predefine FT_DEPRECATED_ATTRIBUTE as void
  4378. to avoid warning in building FreeType.
  4379. * builds/mac/ftmac.c: Ditto.
  4380. 2007-02-05 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  4381. * src/base/ftbase.c: Fix to use builds/mac/ftmac.c, if configured

  4412. =========================
  4413. Tag sources with `VER-2-3-1-FINAL'.
  4414. * builds/win32/visualc/freetype.dsp,
  4415. builds/win32/visualc/freetype.vcproj: s/230/231/.
  4416. * builds/win32/visualc/index.html: s/221/231/.
  4417. * vms_make.com: Add `ftgasp'.
  4418. 2007-01-30 David Turner <david@freetype.org>
  4419. Tag sources with VER-2-3-1 to prepare release.
  4420. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
  4421. * docs/VERSION.DLL, docs/release, README, Jamfile (RefDoc):
  4422. s/2.3.0/2.3.1/.
  4423. * builds/unix/configure.raw (version_info): Set to 9:12:3.
  4424. * src/autofit/aftypes.h (AF_USE_WARPER), src/autofit/afloader.c
  4425. (af_loader_load_g): Disable the warper (i.e., the light hinting
  4426. improvements) to make a 2.3.1 bugfix release before introducing a
  4427. new feature. This should give us more time to tune and improve the
  4428. warper for the next release.
  4429. * docs/CHANGES: Update accordingly.
  4430. 2007-01-25 David Turner <david@freetype.org>
  4431. For light auto-hinting, improve glyph advance widths and resurrect
  4432. normal/full hinting to its normal quality.
  4433. * src/autofit/afhints.h (AF_GlyphHintsRec): New members `xmin_delta'
  4434. and `xmax_delta'.
  4435. * src/autofit/afhints.c (af_glyph_hints_reload): Reset `xmin_delta'
  4436. and `xmax_delta'.
  4437. * src/autofit/afloader.c (af_loader_load_g) <AF_USE_WARPER>: Replace
  4438. preprocessor conditional with if-clause, handling both light and
  4439. normal mode.
  4440. * src/autofit/afwarp.c (AF_WarpScore): Fine-tune again.

  4451. * src/cff/cffload.c (cff_index_get_pointers): Handle last entry
  4452. correctly in a sanity check. Since this function is only used to
  4453. load local and global functions, any charstring that called the last
  4454. local/global function would fail otherwise. This fixes Savannah bug
  4455. #18867.
  4456. * docs/CHANGES: Document it.
  4457. 2007-01-23 David Turner <david@freetype.org>

  4459. prevented compilation when disabling both the unpatented and the
  4460. bytecode interpreter in the TrueType font driver.

  4462. not necessarily a final version, but it seems to work well.
  4463. * src/autofit/aflatin.c (af_latin_hints_init) [AF_USE_WARPER]:
  4464. Disable code.
  4465. (af_latin_hints_apply) [AF_USE_WARPER]: Handle FT_RENDER_MODE_LIGHT.
  4466. * src/autofit/aftypes.h: Activate AF_USE_WARPER.
  4467. * src/autofit/afwarp.c (AF_WarpScore): Tune table.
  4468. (af_warper_compute_line_best): Fix array size of `scores'.
  4469. (af_warper_compute): Better handling of border cases.
  4470. * src/autofit/afwarp.h (AF_WarperRec): Remove unused members `X1'
  4471. and `X2'.
  4472. 2007-01-21 Werner Lemberg <wl@gnu.org>
  4473. * ChangeLog: Split off older entries into...
  4474. * ChangeLog.22: This new file.
  4475. 2007-01-21 Werner Lemberg <wl@gnu.org>
  4476. * docs/CHANGES: Document SHZ fix.
  4477. 2007-01-21 George Williams <gww@silcom.com>
  4478. * src/truetype/ttinterp.c (Ins_SHZ): SHZ doesn't move phantom
  4479. points.
  4480. 2007-01-21 Werner Lemberg <wl@gnu.org>

  4488. * docs/release: Updated.
  4489. 2007-01-16 David Turner <david@freetype.org>
  4490. * src/autofit/aflatin.c (af_latin_hints_compute_segments),
  4491. src/cff/cffdriver.c (cff_ps_get_font_info), src/truetype/ttobjs.c
  4492. (tt_face_init), src/truetype/ttinterp.c (Ins_SHC): Fix compiler
  4493. warnings.
  4494. 2007-01-15 Detlef Würkner <TetiSoft@apg.lahn.de>
  4495. * builds/amiga/makefile, builds/amiga/makefile.os4,
  4496. builds/amiga/smakefile: Add `ftgasp.c' and `ftlcdfil.c'.
  4497. * builds/amiga/include/freetype/config/ftconfig.h: Synchronize.
  4498. 2007-01-14 Detlef Würkner <TetiSoft@apg.lahn.de>
  4499. Fix various compiler warnings.
  4500. * src/truetype/ttdriver.c (tt_size_select), src/cff/cffobjs.h,
  4501. src/cff/cffobjs.c (cff_size_request), src/type42/t42objs.h:
  4502. s/index/strike_index/.
  4503. * src/base/ftobjs.c (FT_Match_Size): s/index/size_index/.
  4504. * src/gxvalid/gxvmorx5.c
  4505. (gxv_morx_subtable_type5_InsertList_validate): s/index/table_index/.
  4506. * src/truetype/ttinterp.c (Compute_Point_Displacement),
  4507. src/pcf/pcfread.c (pcf_seek_to_table_type): Avoid possibly
  4508. uninitialized variables.
  4509. 2007-01-13 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  4510. * docs/CHANGES, docs/INSTALL.MAC: Improvements.
  4511. 2007-01-13 Werner Lemberg <wl@gnu.org>
  4512. * src/type1/t1afm.c (T1_Read_Metrics): MS Windows allows PFM
  4513. versions up to 0x3FF without complaining.
  4514. 2007-01-13 Derek Clegg <dclegg@apple.com>
  4515. Add FT_Get_PS_Font_Info interface to CFF driver.

  4524. with C++ compiler.
  4525. * src/autofit/afhints.c (af_glyph_hints_dump_segments,
  4526. af_glyph_hints_dump_edges): Ditto.
  4527. * src/base/rules.mk (BASE_SRC): Remove ftgasp.c (it's already in
  4528. `modules.cfg').
  4529. * src/sfnt/ttsbit0.h: Remove.
  4530. * src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c.
  4531. 2007-01-12 David Turner <david@freetype.org>
  4532. * src/base/ftbitmap.c (ft_bitmap_assure_buffer): Fix memory stomping
  4533. bug in the bitmap emboldener if the pitch of the source bitmap is
  4534. much larger than its width.
  4535. * src/truetype/ttinterp.c (Update_Max): Fix aliasing-related
  4536. compilation warning.

  4550. Yamato.
  4551. * autogen.sh: Small fix to get it working on Mac OS X properly:
  4552. The issue is that GNU libtool is called `glibtool' on this platform,
  4553. and we must call `glibtoolize', since `libtoolize' doesn't exist.
  4554. 2007-01-10 David Turner <david@freetype.org>
  4555. * all-sources: Tag all sources with VER-2-3-0-RC1 and

  4591. * src/cff/cffload.c (cff_index_init): Remove unused variable.
  4592. (cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.
  4593. 2007-01-04 David Turner <david@freetype.org>
  4594. * src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
  4595. correctly. This fixes Savannah bug #17876.
  4596. Do not allocate interpreter-specific tables in memory if we are not
  4597. going to load glyphs with the bytecode interpreter anyway.

  4609. Don't extract the metrics table from the SFNT font file. Instead,

  4611. noticeable, and it can save a lot of heap memory when memory-mapped
  4612. files are not used.
  4613. * include/freetype/internal/tttypes.h (TT_FaceRec): Add members
  4614. `horz_metrics_offset' and `vert_metrics_ofset'.

  4616. Updated.
  4617. * src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.
  4618. Do not load the CFF index offsets into memory, since this wastes a
  4619. *lot* of heap memory with large Asian CFF fonts. There is no
  4620. significant performance loss.
  4621. * src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
  4622. * src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
  4623. `data_size'.
  4624. (CFF_CharsetRec): Add field `num_glyphs'.
  4625. * src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
  4626. cff_charset_cid_to_gindex): New functions.

  4630. (cff_done_index): Renamed to...
  4631. (cff_index_done): This. Update all callers.
  4632. (cff_index_get_pointers, cff_index_access_element): Updated to use
  4633. stream offsets.
  4634. (cff_charset_compute_cids): Set `num_glyphs' field.

  4839. Add a few tweaks to better handle serif fonts.
  4840. Add more debugging messages.
  4841. * src/autofit/aflatin.c (af_latin_hints_compute_edges): Ignore
  4842. segments that are less than 1.5 pixels high. This gets rid of
  4843. *many* corner cases with serifs.
  4844. (af_latin_align_linked_edge): Add logging message.
  4845. (af_latin_hint_edges): Use AF_HINTS_DO_BLUES.

  4962. Add a new API to support color filtering of subpixel glyph bitmaps.
  4963. In a default build, the function `FT_Library_SetLcdFilter' returns
  4964. `FT_Err_Unimplemented_Feature'; you need to #define
  4965. FT_CONFIG_OPTION_SUBPIXEL_RENDERING in ftoption.h to compile the
  4966. real implementation.
  4967. * include/freetype/ftlcdfil.h, src/base/ftlcdfil.c: New files.

  4978. * include/freetype/config/ftheader.h (FT_LCD_FILTER_H): New macro,
  4979. pointing to <freetype/ftlcdfil.h>.
  4980. * src/base/Jamfile (_sources), src/base/rules.mk (BASE_SRC),
  4981. vms_make.com: Add `ftlcdfil.c' to the list of compiled source files.

  4997. not. The macro *must* be disabled in default builds of the library
  4998. for patent reasons.
  4999. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Disable
  5000. LCD-specific rendering when FT_CONFIG_OPTION_SUBPIXEL_RENDERING
  5001. isn't defined at compile time. This only changes the content of the
  5002. rendered glyph to match the one of normal gray-level rendering,
  5003. hence clients should not need to be modified.
  5004. * docs/CHANGES: Updated.
  5005. 2006-09-18 Garrick Meeker <garrick@digitalanarchy.com>

  5018. values which have the upper two bytes set to 0xFF instead of 0x00
  5019. (as it happens in at least two CJKV fonts, `HAN NOM A.ttf' and
  5020. `HAN NOM B.ttf').

  5277. to PCF_Face_Done can do the clean-up in case of error.
  5278. Protect against invalid string offsets.
  5279. (pcf_get_metrics): Clean up code.
  5280. Adjust tracing message levels.
  5281. Use rough estimate to get array size limit.
  5282. (pcf_get_bitmaps): Clean up code.
  5283. Adjust tracing message levels.
  5284. Use rough estimates to get offset limits.
  5285. (pcf_get_encodings): Adjust tracing message level.
  5286. (pcf_get_accel): Clean up code.
  5287. 2006-06-26 Werner Lemberg <wl@gnu.org>
  5288. * src/bdf/bdfdrivr.c (BDF_Face_Init): Handle fonts correctly which
  5289. don't have a POINT_SIZE property. This fixes Savannah bug #16914.
  5290. 2006-06-26 Jens Claudius <jens.claudius@yahoo.com>
  5291. * src/psaux/t1decode.c (T1_Operator, t1_args_count): Add opcode 15.
  5292. (t1_decoder_parse_charstrings): Operator with
  5293. opcode 15 pops its two arguments.
  5294. Handle the case where the pops of an othersubr may be part of a
  5295. subroutine.
  5296. Handle unknown othersubrs gracefully: count their operands and let
  5297. the following pop operators push the operands as the results onto
  5298. the Type1 stack.
  5299. Improve handling of setcurrentpoint opcode.
  5300. 2006-06-25 Jens Claudius <jens.claudius@yahoo.com>
  5301. The Type 1 parser now skips over top-level procedures as required
  5302. for a `Simplified Parser'. This makes the parser more robust as it
  5303. doesn't poke around in PostScript code. Additionally, it makes the
  5304. FontDirectory hackery in src/type1/t1load.c unnecessary.
  5305. * src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
  5306. (skip_literal_string): Add FT_Error as return value.
  5307. Handle escapes better.
  5308. (skip_string): Add FT_Error as return value.
  5309. Don't set `parser->error' but return error code directly.
  5310. (skip_procedure): New function.
  5311. (ps_parser_skip_PS_token): Handle procedures.
  5312. Update code.
  5313. (ps_parser_to_token): Update code.
  5314. (ps_parser_load_field_table): Handle bbox entries also.
  5315. * src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
  5316. Add commented-out code for synthetic fonts.
  5317. 2006-06-24 Eugeniy Meshcheryakov <eugen@univ.kiev.ua>
  5318. Fix two hinting bugs as reported in
  5319. http://lists.gnu.org/archive/html/freetype-devel/2006-06/msg00057.html.
  5320. * include/freetype/internal/tttypes.h (TT_GlyphZoneRec): Add
  5321. `first_point' member.
  5322. * src/truetype/ttgload.c (tt_prepare_zone): Initialize
  5323. `first_point'.
  5324. (TT_Process_Composite_Glyph): Always untouch points.
  5325. * src/truetype/ttinterp.c (Ins_SHC): Fix computation of
  5326. `first_point' and `last_point' in case of composite glyphs.
  5327. (Ins_IUP): Fix computation of `end_point'.
  5328. 2006-06-22 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  5329. Insert EndianS16_BtoN and EndianS32_BtoN as workaround for Intel
  5330. Mac. The original patch was written by David Sachitano and Lawrence
  5331. Coopet, and modified by Sean McBride for MPW compatibility. Only
  5332. required data are converted; unused data are left in big endian.
  5333. * src/base/ftmac.c: Include <Endian.h> for byteorder macros for non
  5334. Mac OS X platforms.
  5335. (OS_INLINE): Undefine before definition.
  5336. (count_faces_sfnt): Insert EndianS16_BtoN to parse the header of
  5337. FontAssociation table in FOND resource.
  5338. (count_faces_scalable): Insert EndianS16_BtoN to parse the header
  5339. and fontSize at each entry of FontAssociation table in FOND
  5340. resource.
  5341. (parse_fond): Insert EndianS16_BtoN and EndianS32_BtoN to parse
  5342. ffStylOff of FamilyRecord header of FOND resource, the header,
  5343. fontSize, fontID at each entry of FontAssociation table, and
  5344. StyleMapping table.
  5345. (count_faces): Call `HUnlock' after all FOND utilization.
  5346. 2006-06-08 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  5347. Public API of TrueTypeGX, OpenType, and classic kern table validator
  5348. should return `FT_Err_Unimplemented_Feature' if validation service
  5349. is unavailable (disabled in `modules.cfg'). It is originally
  5350. suggested by David Turner, cf.
  5351. http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html
  5352. * src/base/ftgxval.c (FT_TrueTypeGX_Validate): Return
  5353. FT_Err_Unimplemented_Feature if TrueTypeGX validation service is
  5354. unavailable.
  5355. (FT_ClassicKern_Validate): Return FT_Err_Unimplemented_Feature if
  5356. classic kern table validation service is unavailable.
  5357. * src/base/ftotval.c (FT_OpenType_Validate): Return
  5358. FT_Err_Unimplemented_Feature if OpenType validation service is
  5359. unavailable.
  5360. 2006-06-08 Werner Lemberg <wl@gnu.org>
  5361. * src/bdf/bdflib.c (bdf_load_font): Fix memory leaks in case of
  5362. errors.
  5363. 2006-06-07 David Turner <david@freetype.org>
  5364. * src/type1/t1afm.c (KERN_INDEX): Make it more robust.
  5365. (T1_Read_Metrics): Fix memory leak which happened when the metrics
  5366. file doesn't have kerning pairs. This fixes Savannah bug #16768.
  5367. 2006-06-06 David Turner <david@freetype.org>
  5368. Fix memory leak described in Savannah bug #16759.
  5369. We change `ps_unicodes_init' so that it also takes a
  5370. `free_glyph_name' callback to release the glyph names returned by
  5371. `get_glyph_name'
  5372. * include/freetype/internal/services/svpscmap.h (PS_Glyph_NameFunc):
  5373. Renamed to ...
  5374. (PS_GetGlyphNameFunc): This.
  5375. (PS_FreeGlyphNameFunc): New typedef.
  5376. (PS_Unicodes_InitFunc): Add variable for PS_FreeGlyphNameFunc.
  5377. * src/cff/cffcmap.c (cff_sid_to_glyph_name): Use `TT_Face' for first
  5378. argument.
  5379. (cff_sid_free_glyph_name): New function.
  5380. (cff_cmap_unicode_init): Updated.
  5381. * src/psaux/t1cmap.c (t1_cmap_unicode_init): Updated.
  5382. * src/psnames/psmodule.c (ps_unicodes_init): Add variable for
  5383. PS_FreeGlyphNameFunc and use it.
  5384. 2006-06-04 David Turner <david@freetype.org>
  5385. * src/base/ftutil.c (ft_mem_qrealloc): Fix the function to accept
  5386. `item_size == 0' as well -- though this sounds weird, it can
  5387. theoretically happen. This fixes Savannah bug #16669.
  5388. * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
  5389. of `face->num_glyphs' which missed the last glyph, due to
  5390. the offset-by-1 computation, since the PFR format doesn't
  5391. guarantee that glyph index 0 corresponds to the `missing
  5392. glyph. This fixes Savannah bug #16668.
  5393. 2006-05-25 Werner Lemberg <wl@gnu.org>
  5394. * builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
  5395. `-no-undefined'. Reported by Christian Biesinger.
  5396. 2006-05-19 Brian Weed <bw@imaginengine.com>
  5397. * builds/win32/visualc/freetype.dsp: Release libraries no longer
  5398. have debug information, and debug libraries use `C7 compatible'
  5399. debug info.
  5400. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  5401. Apply patch by Derek Clegg to fix two memory leaks in the MacOS
  5402. resource fork handler. This fixes Savannah bug #16631.
  5403. * src/base/ftobjs.c (load_face_in_embedded_rfork): Replace
  5404. `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.
  5405. * src/base/ftrfrk.c (raccess_guess_linux_double_from_file_name):
  5406. Replace `FT_Stream_Close' by `FT_Stream_Free' to fix memory leak.
  5407. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  5408. * build/unix/configure.raw: Add a fallback to disable Carbon
  5409. dependency, if configured with no options on Mac OS X.
  5410. 2006-05-19 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp>
  5411. * src/base/ftmac.c (open_face_from_buffer): Deallocate stream when
  5412. its content cannot be parsed as supported font. This fixes
  5413. the second part of Savannah bug #16590.
  5414. 2006-05-18 Werner Lemberg <wl@gnu.org>
  5415. * src/truetype/ttgload.c (TT_Load_Composite_Glyph)
  5416. [FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.
  5417. 2006-05-17 David Turner <david@freetype.org>
  5418. This is a major patch used to drastically improve the performance of
  5419. loading glyphs. This both speeds up loading the glyph vectors
  5420. themselves and the auto-fitter module.
  5421. We now use inline assembler code with GCC to implement `FT_MulFix',
  5422. which is probably the most important function related to the
  5423. engine's performance.
  5424. The resulting speed-up is about 25%.
  5425. * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
  5426. `cursor' and `limit'.
  5427. * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
  5428. New functions.
  5429. (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
  5430. [TEST]: Remove.
  5431. * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
  5432. code.
  5433. * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
  5434. `FT_ZERO'
  5435. (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
  5436. (af_glyph_hints_reload: Rewrite recognition of weak points.
  5437. * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
  5438. constant values out of the loops.
  5439. * src/autofit/aftypes.h: Updated.
  5440. * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
  5441. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
  5442. product to get orientation.
  5443. * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
  5444. (FT_Stream_OpenGzip): Use it to handle small files directly in
  5445. memory.
  5446. * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
  5447. Improve performance.
  5448. * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
  5449. `limit'.
  5450. (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
  5451. TT_Load_Composite_Glyph): Updated. Add threshold to protect against
  5452. exceedingly large values of number of contours. Speed up by
  5453. reducing the number of loops.
  5454. * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
  5455. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
  5456. used to detect rogue clients from 4 to 16. This is to prevent some
  5457. segmentation faults with fonts like `KozMinProVI-Regular.otf' which
  5458. comes from the Japanese Adobe Reader Asian Font pack.
  5459. 2007-05-17 Werner Lemberg <wl@gnu.org>
  5460. * src/cff/cffload.c (cff_font_done): Deallocate subfont array. This
  5461. fixes the first part of Savannah bug #16590.
  5462. 2006-05-16 Werner Lemberg <wl@gnu.org>
  5463. * docs/PROBLEMS: Updated icl issues.
