Werner Lemberg c52b129c 2013-11-13T10:06:00 * builds/unix/ft2unix.h: Remove. No longer necessary. * builds/unix/install.mk (install): Updated.
Werner Lemberg fae38207 2013-11-13T08:55:46 Simplify header file hierarchy. This large patch changes the header file directory layout from `include/freetype/...' to `include/...', effectively removing one level. Since the file `ft2build.h' is also located in `include' (and it stays there even after installation), all FreeType header files are now in a single directory. Applications that use (a) `freetype-config' or FreeType's `pkg-config' file to get the include directory for the compiler, and (b) the documented way for header inclusion like #include <ft2build.h> #include FT_FREETYPE_H ... don't need any change to the source code. * include/freetype/*: Move up to... * include/*: ... this directory. * builds/amiga/include/freetype/*: Move up to... * builds/amiga/include/*: ... this directory. */*: Essentially do `s@/freetype/@/@' where appropriate. * CMakeList.txt: Simplify. * builds/unix/freetype-config.in, builds/unix/freetype2.in: For `--cflags', return a single directory. * builds/unix/install.mk (install): No longer try to remove `cache' and `internal' subdirectories; instead, remove the `freetype' subdirectory.
Werner Lemberg ea5c781a 2013-11-12T08:55:26 [truetype] Fix last `truetype' commit. * src/truetype/ttgload.c (tt_get_metrics): Preserve stream position. Return error value. (load_truetype_glyph): Updated.
Werner Lemberg 7833328b 2013-11-10T06:26:52 * docs/CMAKE: New dummy file.
Dave Arnold dd21301e 2013-11-08T10:52:51 [cff] Fix for hints that touch. * src/cff/cf2hints.c (cf2_hintmap_insertHint): Fix condition for finding index value of insertion point.
Werner Lemberg 5e225b7c 2013-11-06T08:41:59 [truetype] Fix handling of phantom points in composite glyphs. Problem reported by Nigel Tao <nigeltao@golang.org>. This is a follow-up commit to the previous one. * src/truetype/ttgload.c (load_truetype_glyph): Call `tt_get_metrics' after loading the glyph header.
Werner Lemberg 7e4b0fbf 2013-11-06T07:14:49 [truetype] Improve emulation of vertical metrics. This commit also improves the start values of vertical phantom points. Kudos to Greg Hitchcock for help. * src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass `yMax' value. Replace code with fixed Microsoft definition. (tt_get_metrics): Updated. (TT_LOADER_SET_PP): Add explanation how to initialize phantom points, taken from both the OpenType specification and private communication with Greg (which will eventually be added to the standard). Fix horizontal position of `pp3' and `pp4'. * src/truetype/ttgload.h: Updated. * src/truetype/ttdriver.c (tt_get_advances): Updated. * docs/CHANGES: Updated.

Werner Lemberg 50740536 2013-11-05T23:19:18 * builds/windows/vc2010/freetype.vcxproj: s/v110/v100/. PlatformToolSet version 110 is for VC2012. Problem reported (with solution) by Dave Arnold <darnold@adobe.com>.
Werner Lemberg c6064286 2013-11-05T13:29:15 [truetype] Correctly reset point tags for glyph components. Problem reported by Nigel Tao <nigeltao@golang.org>. * src/truetype/ttgload.c (TT_Process_Composite_Glyph): Fix loop.
Werner Lemberg e4db8127 2013-11-03T20:29:37 Typos.
Werner Lemberg 7d449436 2013-11-02T11:36:37 [truetype] Fix GETINFO opcode handling of subpixel hinting bits. * src/truetype/ttinterp.c (Ins_GETINFO): Don't request bit 6 set to get info on subpixel hinting. * docs/CHANGES: Updated.
Werner Lemberg 35b08189 2013-11-02T08:28:41 Fix Savannah bug #40451. Simply apply the patch from the bug report. * builds/unix/ftconfig.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: The used #pragma directives only work with gcc versions 4.6 and higher.
Werner Lemberg afa0d59e 2013-11-01T22:27:27 * docs/CHANGES: Updated.
Werner Lemberg ebf52d6a 2013-11-01T13:26:28 [truetype] Minor code refactoring. Two benefits: The allocated FDEF (and IDEF) array gets slightly smaller, and the `ttdebug' demo program has access to function numbers without additional costs. Fortunately, no changes to FontForge are necessary – this is the only external TrueType debugger I know of, but others may exist and should check the code accordingly. * src/truetype/ttinterp.h (TT_CallRec): Replace `Cur_Restart' and `Cur_End' with a pointer to the corresponding `TT_DefRecord' structure. * src/truetype/ttinterp.c (DO_JROT, DO_JMPR, DO_JROF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_UNKNOWN, TT_RunIns <Invalid_Opcode>): Updated.

Werner Lemberg ee510510 2013-10-27T07:25:35 [sfnt] Implement support for `OS/2' table version 5. See http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism for the announcement. * include/freetype/tttables.h (TT_OS2): Add fields `usLowerPointSize' and `usUpperPointSize'. Since FreeType returns this structure only as a pointer through `FT_Get_Sfnt_Table', there shouldn't be any ABI problems. * src/sfnt/ttload.c (tt_face_load_os2): Implement it. * docs/CHANGES: Updated.
Werner Lemberg 994a8598 2013-10-24T08:50:34 * README.git, docs/CHANGES, docs/INSTALL: Updated.

Werner Lemberg 604838d5 2013-10-22T01:10:10 * src/base/md5.c, src/base/md5.h: Updated to recent version. * src/base/ftobjs.c: Updated; `md5.c' no longer uses `free'.
Werner Lemberg 75efc2d0 2013-10-19T21:46:03 [autofit] s/SMALL_TOP/X_HEIGHT/. * src/autofit/afblue.dat: Updated. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.c, src/autofit/aflatin.h, src/autofit/atlatin2.c: Updated.
Werner Lemberg 34efe05c 2013-10-19T21:14:40 * src/autofit/afblue.dat: s/MINOR/DESCENDER/. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
Werner Lemberg a5f22a9e 2013-10-17T11:08:25 [autofit] Add description strings to script entries. Currently, this is unused. * src/autofit/afscript.h: Do it. * src/autofit/afglobal.c, src/autofit/afpic.c, src/autofit/aftypes.h: Updated.
Werner Lemberg 955f6a86 2013-10-16T19:47:57 [autofit] Improve tracing message for extra light flag. * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Do it.
Chongyu Zhu 41632b58 2013-10-15T11:40:34 [arm] Fix thumb2 inline assembly under LLVM. When using `ADD' with an immediate operand, the instruction is actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the immediate operand cannot exceed 4095. It will fail to compile with LLVM. However, in GCC, due to some legacy compatibility considerations, `ADD.W' will be automatically emitted when the immediate operand is larger than 4095. * builds/unix/ftconfig.in, include/freetype/config/ftconfig.h (FT_MulFix_arm) [__GNUC__]: Support clang compiler. * src/truetype/ttinterp.c (TT_MulFix14_arm) [__GNUC__]: Ditto.
Werner Lemberg b6695243 2013-10-12T10:33:04 [autofit] Improve tracing of `latin' hinter. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Report blue zone types. (af_latin_metrics_scale_dim): Report scaling changes due to x height alignment. Report scaled stroke width and blue zone values.
Werner Lemberg 2c56f2ab 2013-10-07T22:01:00 Improve last ChangeLog entry.
Dave Arnold e845a85e 2013-10-03T23:04:29 * src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
Werner Lemberg 1a39944f 2013-10-03T06:16:50 Updated CHANGES file.
Darrell Bellert 01af71d4 2013-10-02T22:04:07 * src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.
Dave Arnold 0b330452 2013-10-02T11:04:06 * src/cff/cf2font.c (cf2_computeDarkening): Initialize darkenAmount. This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect is to use a previous darkening amount when producing an unhinted, unscaled outline. This can cause autohint samples in ftgrid and ftview to be based on darkened CFF outlines instead of unhinted, undarkened ones.
Dave Arnold 3a2cb0f8 2013-09-29T16:17:02 Fix Savannah bug #39295. The bug was caused by switching to the initial hintmap (the one in effect when `moveto' executes) just before drawing the final element in the charstring. This ensured that the path was closed (in both Character Space and Device Space). But if the final element was a curve and if the final hintmap was different enough from the initial one, then the curve was visibly distorted. The first part of the fix is to draw the final curve using the final hintmap as specified by the charstring. This corrects the distortion but does not ensure closing in Device Space. It may require the rasterizer to automatically generate an extra closing line. Depending on the hintmap differences, this line could be from zero to a couple pixels in length. The second part of the fix covers the case where the charstring subpath is closed with an explicit line. We now modify that line's end point to avoid the distortion. Some glyphs in the bug report font (TexGyreHeros-Regular) that show the change are: 25ppem S (98) 24ppem eight (52) 25.5ppem p (85) Curves at the *end* of a subpath are no longer distorted. However, some of these glyphs have bad hint substitutions in the middle of a subpath, and these are not affected. The patch has been tested with a set of 106 fonts that shipped with Adobe Creative Suite 4, together with 756 Open Source CFF fonts from Google Fonts. There are 1.5 million glyphs, of which some 20k are changed with the fix. A sampling of a few hundred of these changes have been examined more closely, and the changes look good (or at least acceptable). * src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing' to indicate that we synthesize a closepath line. * src/cff/cf2hints.c (cf2_glyphpath_init): Updated. (cf2_glyphpath_pushPrevElem): If closing, use first hint map (for `lineto' operator) and adjust hint zone. For synthesized closing lines, use end point in first hint zone. (cf2_glyphpath_lineTo): Take care of synthesized closing lines. In particular, shift the detection of zero-length lines from character space to device space. (cf2_glyphpath_closeOpenPath): Remove assertion. Updated.
Werner Lemberg 4f9760e7 2013-09-25T23:32:25 [autofit] Remove outdated comment.
Werner Lemberg b75a8b88 2013-09-25T09:46:36 * src/autofit/aflatin.c (af_{grek,cyrl}_uniranges): Fix arrays.

suzuki toshiya ac0f4454 2013-09-25T10:57:17 [bdf, pcf] Refuse non-zero face_index. Suggested by Akira Tagoh, see http://lists.gnu.org/archive/html/freetype/2013-09/msg00030.html * src/bdf/bdfdrivr.c (BDF_Face_Init): Return Invalid_Argument error when the font could be opened but non-zero face_index is given. * src/pcf/pcfdrivr.c (PCF_Face_Init): Ditto. * src/type42/t42objs.c (T42_Face_Init): Remove unrequired FT_UNUSED macro for face_index because it is validated in later.
Werner Lemberg 4de7787f 2013-09-23T22:10:08 Fix Savannah bug #40090. * src/autofit/afcjk.c (af_cjk_metrics_scale): Revert commit 306f8c5d (from 2013-08-25) affecting this function.

Werner Lemberg 3f542498 2013-09-11T23:08:31 [autofit] Improve Hebrew rendering. This change introduces a new blue zone property `AF_BLUE_PROPERTY_LATIN_LONG' to make the auto-hinter ignore short top segments. * src/autofit/afblue.dat: Fix Hebrew blue strings. Use AF_BLUE_PROPERTY_LATIN_LONG for AF_BLUE_STRING_HEBREW_TOP. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_LONG): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Updated. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle `AF_LATIN_IS_LONG_BLUE'. * src/autofit/aflatin.h (AF_LATIN_IS_LONG_BLUE): New macro.
Werner Lemberg 00ea2a13 2013-09-03T11:33:10 [doc] s/which/that/ where appropriate. Note that this is a try by a non-native English speaker whose mother language (German) doesn't have this distinction at all...
Werner Lemberg 504f5b4a 2013-09-02T22:08:12 Fix Savannah bug #39905 (documentation only).
Werner Lemberg 85a7fdf3 2013-08-29T21:03:05 [sfnt] Fix frame access while reading WOFF table directory. * src/sfnt/sfobjs.c (woff_open_font): Using single memory frame while reading the directory entries for the whole loop.
Werner Lemberg d689d1cf 2013-08-29T17:53:40 Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.
Werner Lemberg dc240524 2013-08-29T17:53:24 [gzip] New function `FT_Gzip_Uncompress'. This is modeled after zlib's `uncompress' function. We need this for WOFF support. * include/freetype/ftgzip.h, src/gzip/ftgzip.c (FT_Gzip_Uncompress): New function. * src/gzip/rules.mk: Rewrite to better reflect dependencies.
Werner Lemberg 5195ecd6 2013-08-28T17:41:21 [autofit] Fix `make multi' compilation. * src/autofit/afblue.cin, src/autofit/afblue.c: Don't include `afblue.h' but `aftypes.h'. * src/autofit/afcjk.c: Don't include `aftypes.h' but `afglobal.h'.

Behdad Esfahbod c799dd67 2013-08-27T21:46:03 * src/sfnt/ttload.c (tt_face_load_font_dir): Fix sign typos.
Behdad Esfahbod bd3849e7 2013-08-27T21:43:38 FT_Open_Face: Improve external stream handling. If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to... (open_face): This function.
Werner Lemberg bcd8c0b0 2013-08-27T21:36:03 Remove `FT_SqrtFixed' function. It's no longer used. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c: Do it.
Werner Lemberg 71c0ad65 2013-08-27T21:30:09 Whitespace.
Werner Lemberg 5e53db25 2013-08-27T18:37:39 [autofit] While tracing, report script names instead of ID values. * src/autofit/afglobal.c (af_script_names) [FT_DEBUG_LEVEL_TRACE]: New array. * src/autofit/afglobal.h: Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_hint_edges): Use `af_script_names'. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hint_edges): Ditto.

Werner Lemberg ffee64af 2013-08-26T12:55:48 Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all. With this change, all font loading routines emit a tracing message at level 1, making it easier to select tracing output (for example using F2_DEBUG="any:1 afhints:7 aflatin:7"). * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message. * src/cff/cffdrivr.c (cff_glyph_load): Ditto. * src/cff/cffgload.c (cff_decoder_prepare): Improve tracing messages. * src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing message. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. * src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.

Werner Lemberg c1eb4459 2013-08-25T19:47:26 [autofit] Make `cjk' module use blue stringsets. * src/autofit/afcjk.c (AF_CJK_MAX_TEST_CHARACTERS): Removed. (af_cjk_hani_blue_chars): Removed. (AF_CJK_BLUE_TYPE_*): Removed. (af_cjk_metrics_init_blues): Replace AF_CJK_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Instead of three dimensions (as used in the old blue string array) we now use properties to do the same, saving one loop nesting level. * src/autofit/afcjk.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE, AF_CJK_IS_RIGHT_BLUE): New macros, to be used in `af_cjk_metrics_init_blues'. (AF_CJK_BLUE_IS_RIGHT): Remove this now redundant enum value. (AF_CJK_BLUE_IS_TOP): Renamed to... (AF_CJK_BLUE_TOP): This. (AF_CJK_MAX_BLUES): Remove. (AF_CJKAxisRec): Updated.
Werner Lemberg 5c4a23a4 2013-08-25T19:29:07 [autofit] Typo. * src/autofit/afblue.hin, src/autofit/afblue.c (GET_UTF8_CHAR): Use cast.
Werner Lemberg 306f8c5d 2013-08-25T13:07:08 [autofit] Synchronize `cjk' with `latin' module (and vice versa). * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Add tracing messages. (af_cjk_metrics_init_blues): Don't pass blue string array as argument but use the global array directly. Use `outline' directly. Update and add tracing messages. (af_cjk_metrics_init): Simplify code. (af_cjk_metrics_scale_dim): Improve tracing message. (af_cjk_metrics_scale): Synchronize. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues): Improve and add tracing messages.
Werner Lemberg 0975d685 2013-08-25T08:37:47 [autofit] Make `latin' module use blue stringsets. * src/autofit/aflatin.c (AF_LATIN_MAX_TEST_CHARACTERS): Removed. (af_latin_blue_chars): Removed. (af_latin_metrics_init_blues): Replace AF_LATIN_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Use `AF_LATIN_IS_SMALL_TOP_BLUE' macro. * src/autofit/aflatin.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_LATIN_IS_TOP_BLUE): Updated definition.

Werner Lemberg 8b8be783 2013-08-25T08:01:41 [autofit] Introduce data file for blue strings. The idea is to have a central file which gets processed by a Perl script to create proper `.c' and `.h' files using templates. There are two other reasons to do that: . The data file should be easily readable. We use UTF-8 encoding which then gets converted to single bytes. . Since the number of supported scripts will increase soon, the current usage of blue string arrays is a waste of space. Using the Perl script it is possible to imitate jagged arrays, defining enumeration constants as offsets into the arrays. This commit only adds files without changing any functionality. * src/autofit/afblue.dat: New data file. * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files for... * src/autofit/afblue.c, src/autofit/afblue.c: New source files. To avoid a dependency on Perl, we add them too.

Werner Lemberg cc25e3ae 2013-08-05T08:46:15 [autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary.

Werner Lemberg 72f5ff5b 2013-07-31T22:49:29 [autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts.
