19241347	2013-12-21T21:31:38	Introduce `coverages'. Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only. Code for handling selected OpenType features (this is, actually using the data in `afcover.h') will follow. * devel/ftoption.h, include/config/ftoption.h (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.

(af_face_globals_compute_style_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'. Update. * src/autofit/afmodule.h (AF_ModuleRec): s/fallback_script/fallback_style/. * src/autofit/afmodule.c (af_property_set): Adapt handling of `fallback-script' property to set a fallback style.

(FT_Init_Table_ft_raccess_guess_table): ... this so that the function name correctly corresponds to what the macro framework expects. * src/psnames/rules.mk (PSNAMES_DRV_SRC_S): Use correct file name so that PIC functions are compiled also.
c4e968ed	2013-12-21T07:23:08	[base] Add missing dependencies to Makefile. * src/base/rules.mk (BASE_SRC): Add `basepic.c' and `ftpic.c'. (BASE_H): Add `basepic.h'.

7a5fc2f3	2013-12-17T13:29:53	[autofit] s/AF_Script_/AF_WritingSystem_/ where appropriate.
8bb09b0f	2013-12-11T09:01:13	[truetype] Simplify logic of rendering modes. This patch unifies the subpixel and non-subpixel cases. * src/truetype/ttinterp.h (TT_ExecContextRec): Remove `grayscale_hinting'; all code should refer to `grayscale' instead. Remove unused `native_hinting' member. Rename `subpixel_hinting' member to `subpixel. * src/truetype/ttgload.c (TT_LOADER_SET_PP): Updated. (tt_loader_init): Updated. * src/truetype/ttinterp.c (Ins_GETINFO): Simplify. Updated.
e9d95aa0	2013-12-11T07:48:51	[documentation] Add section how to include FreeType header files. Problem reported by David Kastrup <dak@gnu.org>. Surprisingly, a description how to do that was completely missing in the API reference. * include/freetype.h, include/ftchapters.h: New documentation section `header_inclusion'.

05c786d9	2013-12-10T08:38:57	[truetype] Fix positioning of composite glyphs. Problem reported by Nigel Tao <nigeltao@golang.org>. * src/truetype/ttgload.c (TT_Hint_Glyph): Remove code that shifts the glyph (component) by a fractional value computed from the LSB phantom point. This is wrong, since the horizontal phantom points get rounded horizontally later on.
dd8050aa	2013-12-08T23:14:46	* Version 2.5.2 released. ========================= Tag sources with `VER-2-5-2'. * docs/VERSION.DLL: Update documentation and bump version number to 2.5.2. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.1/2.5.2/, s/251/252/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 1. * builds/unix/configure.raw (version_info): Set to 17:1:11. * docs/CHANGES: Updated.
98d185c7	2013-12-07T09:26:55	[truetype] Next round in phantom point handling. Greg Hitchcock provided very interesting insights into the complicated history of the horizontal positions of the TSB and BSB phantom points. * src/truetype/ttgload.c (TT_LOADER_SET_PP) [TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and `grayscale_hinting' flags as conditionals for the x position of TSB and BSB.
fcdb7840	2013-12-05T15:53:27	* builds/freetype.mk (FT_CC): Removed. Unused.
64b395cc	2013-12-04T06:18:56	[sfnt] Fix handling of embedded bitmap strikes. This corrects the commit from 2013-11-21. Problem reported by Andrey Panov <panov@canopus.iacp.dvo.ru>. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Fix logic to detect excessive bytes for bit-aligned bitmaps.
c2b47539	2013-12-03T07:01:57	[truetype] Remove dead code. Reported by Nigel Tao <nigeltao@golang.org>. * include/internal/tttypes.h (TT_LoaderRec): Remove unused `preserve_pps' field. * src/truetype/ttgload.c (TT_Hint_Glyph): Updated.
bdd5e75e	2013-12-03T06:57:02	[truetype] Fix phantom point handling. This is a further improvement to the changes from 2013-11-06. * src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points are rounded horizontally, vertical ones are rounded vertically. (TT_LOADER_SET_PP): The horizontal position of vertical phantom points in pre-ClearType mode is zero, as shown in the OpenType specification.
64872a50	2013-12-02T07:51:17	[truetype] Fix change from 2013-11-20. Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to `Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a `IS_HINTED' clause. Also remove redundant check using `maxSizeOfInstructions' – in simple glyphs, the bytecode data comes before the outline data, and a validity test for this is already present.
52166ab0	2013-11-27T10:10:16	[autofit] Fix use of dumping functions in `ftgrid' demo program. * src/autofit/afhints.c (AF_DUMP) [FT_DEBUG_AUTOFIT]: New macro. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges) [FT_DEBUG_AUTOFIT]: Add parameter to handle output to stdout. Use AF_DUMP. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edges) [!FT_DEBUG_AUTOFIT]: Removed.

063ee6b1	2013-11-24T00:19:17	[truetype]: Add tricky font names `hkscsiic.ttf' and `iicore.ttf'. * src/truetype/ttobjs.c (TRICK_NAMES_MAX_CHARACTERS, TRICK_NAMES_COUNT): Updated. (trick_names): Add family name for the two fonts.
9326cafa	2013-11-23T23:59:25	* src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Typo.
8af2a1cd	2013-11-21T13:13:12	[truetype] Typo. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/sfnt/sfobjs.c (sfnt_load_face): Return correct `bsize->width' value if the font lacks an `OS/2' table.
427b1768	2013-11-21T13:10:56	[truetype] Improve handling of buggy embedded bitmap strikes. We are now able to successfully load `AppleMyoungJo.ttf'. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Don't trust glyph format.
28626869	2013-11-20T21:06:18	[truetype] Don't trust `maxp's `maxSizeOfInstructions'. Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html for details. * src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep' tables also for setting `autohint'. * src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from `TT_Process_Composite_Glyph' for handling unreliable values of `maxSizeOfInstructions'.
bc25de66	2013-11-16T07:52:20	[sfnt] Fix `OS/2' table version 5 support. We now follow the `official' announcement from Microsoft (on the OpenType mailing list, which unfortunately hasn't a public archive). * include/freetype/tttables.h (TT_OS2): s/usLowerPointSize/usLowerOpticalPointSize/, s/usUpperPointSize/usUpperOpticalPointSize/. * src/sfnt/ttload.c (tt_face_load_os2): Update, and set correct default values.
c52b129c	2013-11-13T10:06:00	* builds/unix/ft2unix.h: Remove. No longer necessary. * builds/unix/install.mk (install): Updated.
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.
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.
7833328b	2013-11-10T06:26:52	* docs/CMAKE: New dummy file.
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.
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.
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.
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>.
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.
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.
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.
afa0d59e	2013-11-01T22:27:27	* docs/CHANGES: Updated.
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.
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.
994a8598	2013-10-24T08:50:34	* README.git, docs/CHANGES, docs/INSTALL: Updated.
a0e4a73f	2013-10-24T08:49:08	Provide cmake support. * CMakeLists.txt: New file.
4d87ac8a	2013-10-23T20:10:56	Provide support for x64 builds in Visual C++ project files. * src/builds/win32: Renamed to... * src/builds/windows: This. * src/builds/windows/vc2010/: Updated to handle x64 target. src/builds/windows/*.mk, docs/INSTALL.GNU: s/win32/windows/ where appropriate.
db9159c4	2013-10-22T10:27:50	Add md5 URL.
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'.
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.
34efe05c	2013-10-19T21:14:40	* src/autofit/afblue.dat: s/MINOR/DESCENDER/. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
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.
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.
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.
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.

e845a85e	2013-10-03T23:04:29	* src/cff/cf2font.c (cf2_computeDarkening): Avoid division by zero.
01af71d4	2013-10-02T22:04:07	* src/sfnt/ttload.c (tt_face_load_pclt): Fix `pclt_fields'.
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.
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.

52381c14	2013-09-11T23:25:56	* include/freetype/ftoutln.h: Correct FT_Outline_Get_Orientation algorithm description.
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.

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.
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.

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.
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.

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.

(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'.

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.

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. (AF_LATIN_IS_SMALL_TOP_BLUE): New macro. (AF_LATIN_MAX_BLUES): Remove. (AF_LatinAxisRec): Updated.
db3e5b93	2013-08-25T08:23:22	[autofit] Add blue stringsets. * src/autofit/aftypes.h: Include `afblue.h'. (AF_ScriptClassRec): Add `blue_stringset' field.

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.
fc32e1c8	2013-08-19T22:57:05	[base] Enable new algorithm for BBox_Cubic_Check. * src/base/ftbbox.c: Enable new BBox_Cubic_Check algorithm, remove the old one. Improve comments.

32a7d870	2013-08-17T22:19:21	[base] Clean up BBox_Conic_Check. * src/base/ftbbox.c (BBox_Conic_Check): Remove redundant checks for extremum at the segment ends, which are already within the bbox. Slightly modify calculations.

Introduce `coverages'. Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only. Code for handling selected OpenType features (this is, actually using the data in `afcover.h') will follow. * devel/ftoption.h, include/config/ftoption.h (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros.

(AF_SCRIPT_FALLBACK): Renamed to ... (AF_STYLE_FALLBACK): ... this. * src/autofit/afglobal.c: Include `hbshim.c'. Update use of `SCRIPT' and `STYLE' macros. (af_face_globals_compute_style_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'. Update. * src/autofit/afmodule.h (AF_ModuleRec): s/fallback_script/fallback_style/. * src/autofit/afmodule.c (af_property_set): Adapt handling of `fallback-script' property to set a fallback style. (af_property_get, af_autofitter_init): Updated. * src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros. * src/autofit/afranges.h: Update use of `SCRIPT' macro. * src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include `hbshim.c'. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `hbshim.c'.

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.

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.

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.

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.

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.

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.

[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'.

[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.
