Werner Lemberg 5018477f 2014-12-07T08:17:12 Minor.
Werner Lemberg ed6a9df0 2014-12-06T23:28:58 Whitespace.
Werner Lemberg f34f1925 2014-11-26T21:59:21 * src/*: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. * src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'.

Werner Lemberg 6689a009 2014-11-25T08:53:09 [Savannah bug #43682] Properly handle missing return errors. The functions in this patch *do* return non-trivial errors that must be taken care of. * src/autofit/afloader.c (af_loader_load_g), src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c (FT_Outline_Render), src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_endchar>, src/psaux/psobjs.c (ps_parser_load_field_table), src/psaux/t1decode (t1_decoder_parse_charstrings) <op_endchar>, src/truetype/ttgload.c (load_truetype_glyph <subglyph loop>, tt_loader_init, TT_Load_Glyph), src/truetype/ttgxvar.c (TT_Set_MM_Blend), src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Do it.
Werner Lemberg b24e8ba2 2014-11-25T08:30:49 [Savannah bug #43682] Add/remove `void' casts to some functions. We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it.
Werner Lemberg ef439fd2 2014-11-25T08:14:15 [Savannah bug #43682] Change some signatures to `void' return type. * include/internal/pshints.h (PSH_Globals_SetScaleFunc), include/internal/sfnt.h (TT_Get_Metrics_Func), src/pshinter/pshglob.c (psh_globals_set_scale), src/pshinter/pshrec.c (ps_hints_init), src/sfnt/ttmtx.c (tt_face_get_metrics), src/truetype/ttinterp.c (TT_Goto_CodeRange, TT_Set_CodeRange, TT_Clear_CodeRange, TT_Done_Context, TT_Save_Context): Do it. * src/pshinter/pshglob.h, src/pshinter/pshrec.h, src/sfnt/ttmtx.h, src/truetype/ttgload.c (TT_Hint_Glyph), src/truetype/ttinterp.c (TT_Run_Context), src/truetype/ttinterp.h, src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Updated.
Werner Lemberg eca0f067 2014-11-24T10:22:08 [truetype] Fix Savannah bug #43679. * src/truetype/ttpload.c (tt_face_load_hdmx): Check minimum size of `record_size'.
Infinality facfc79a 2014-11-03T07:24:59 * src/truetype/ttsubpix.c (COMPATIBILITY_MODE_Rules): Updated. The previous commit deteriorates rendering of DejaVu and similar fonts; this gets compensated with this rule.
Werner Lemberg 706f752b 2014-11-03T07:20:57 * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting. Before this patch, it was impossible to ever call DELTAP[123] in subpixel hinting mode as described in the ClearType whitepaper; it only worked if in `compatibility mode'. However, compatibility mode essentially disables SHPIX, completely ruining hinting of ttfautohint output, for example. We now follow the whitepaper more closely so that DELTAP[123] instructions for touched points in the non-subpixel direction are executed.
Alexei Podtelezhnikov 118e651b 2014-10-19T23:31:08 [truetype] Clean up bytecode rounding. Zero distance does not have to be treated specially if you follow specifications and check the sign as the very last step of rounding. * src/truetype/ttinterp.c (Round_None, Round_To_Grid, Round_Down_To_Grid, Round_Up_To_Grid, Round_To_Double_Grid): Use macros when available, do not check for non-zero distance. (Round_To_Half_Grid, Round_Super, Round_Super_45): Ditto, return phase if sign changed.
Alexei Podtelezhnikov d4aabda3 2014-10-18T10:10:04 [truetype] Unwrap engine compensation settings. * src/truetype/ttobjs.c (tt_size_init_bytecode): Updated.
Werner Lemberg 03987bfd 2014-10-16T07:19:46 A better fix for Savannah bug #43392. Suggested by Doug Felt <dougfelt@gmail.com>. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Set `vertAdvance' to zero... * src/truetype/ttgload.c (TT_Load_Glyph): ... and set here a default value for `vertAdvance' based on `linearVertAdvance' in case `vertAdvance' is zero. Note that the previous computed ad-hoc value for `linearVertAdvance' was apparently not tested in a real-life situation.
Alexei Podtelezhnikov 7e83f068 2014-10-14T23:03:56 [truetype] Limit delta shift range. The legal range for delta shift is zero through six. Negative values are illegal according to https://developer.apple.com/fonts/TrueType-Reference-Manual/RM04/Chap4.html#delta%20shift * src/truetype/ttobjs.h (delta_shift, delta_base): Make unsigned. * src/truetype/ttinterp.h (DO_SDS): Throw an error if delta_shift out of range. (Ins_DELTAP, Ins_DELTAC): Optimize for legal delta_shift.
Alexei Podtelezhnikov 125c3ca8 2014-09-02T22:38:59 [truetype] Shortcut ppem calculations for square pixels. * src/truetype/ttinterp.h (TT_ExecContextRec): New field `cur_ppem_func' with a function pointer. * src/truetype/ttinterp.c (TT_RunIns): Initialize `cur_ppem_func' depending on the pixel geometry to either... (Current_Ppem_Stretched): ... this for stretched pixels. (Current_Ppem): ... or this for square pixels. (DO_MPPEM, DO_MPS, Ins_DELTAP, Ins_DELTAC): Use `cur_ppem_func'.
Behdad Esfahbod 1ec98b29 2014-08-31T08:47:11 Don't use `register' keyword. Fixes compiler warnings. * src/base/ftcalc.c (FT_Add64) [!FT_LONG64]: Do it. * src/gzip/inftrees.c (huft_build): Ditto. * src/truetype/ttinterp.c (TT_MulFix14_arm): Ditto.
Alexei Podtelezhnikov a8bc49e1 2014-08-24T22:14:01 [truetype] Optimize DELTAP and DELTAC. * src/truetype/ttinterp.c (Ins_DELTAP, Ins_DELTAC): Move ppem calculations outside of the loop.
Werner Lemberg 441b3f38 2014-07-13T02:28:14 [truetype] Improve handling of buggy `prep' tables. In case of an error in the `prep' table, no longer try to execute it again and again. This makes FreeType handle endless loops in buggy fonts much faster. * src/truetype/ttobjs.h (TT_SizeRec): The fields `bytecode_ready' and `cvt_ready' are now negative if not initialized yet, otherwise they indicate the error code of the last run. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep, tt_size_done_bytecode, tt_size_init_bytecode, tt_size_ready_bytecode, tt_size_init, tt_size_done, tt_size_reset): Updated. * src/truetype/ttgload.c (tt_loader_init): Updated. * src/truetype/ttinterp.c (TT_RunIns): Force reexecution of `fpgm' and `prep' only if we are in the `glyf' table.
Werner Lemberg 6497b9c5 2014-06-13T09:28:00 Fix compiler warnings. Reported by Wojciech Mamrak <wmamrak@gmail.com>. * src/autofit/afglobal.c (af_face_globals_compute_style_coverage), src/autofit/afmodule.c (af_property_set): Fix `signed' vs. `unsigned' issues. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Make compiler happy. * src/base/ftlcdfil.c (_ft_lcd_filter_fir): Use only four elements for `fir'. Fix `signed' vs. `unsigned' issues. * src/sfnt/sfobjs.c (WRITE_BYTE): Removed, unused. (WRITE_USHORT, WRITE_ULONG): Add proper casts. * src/truetype/ttgload.c (TT_Get_VMetrics): Add proper casts. * src/truetype/ttinterp.c (Ins_DELTAP): Add proper casts for `B1' and `B2'.
Sean McBride b24e8d33 2014-03-06T14:54:22 Remove more clang analyzer warnings. * src/bdf/bdflib.c (_bdf_readstream), src/truetype/ttgload.c (TT_Load_Glyph): Remove dead stores.
Sean McBride 7be2a94a 2014-02-08T13:55:38 Fix clang static analyzer and compiler warnings. * src/autofit/afhints.c (af_glyph_hints_align_weak_points), src/autofit/afloader (af_loader_load_g) <FT_GLYPH_FORMAT_COMPOSITE>, src/base/ftcalc.c (FT_MSB), src/base/ftoutln.c (FT_Outline_Decompose), src/bdf/bdfdrivr.c (bdf_interpret_style), src/cff/cffparse.c (cff_parse_integer), src/cid/cidparse.c (cid_parser_new), src/pfr/pfrload.c (pfr_phy_font_load), src/raster/ftraster.c (Decompose_Curve), src/sfnt/sfdriver.c (sfnt_get_ps_name), src/sfnt/ttcmap.c (tt_cmap12_next, tt_cmap13_next), src/smooth/ftgrays.c (gray_hline): Remove dead code. * src/autofit/afmodule.c (af_property_get_face_globals, af_property_set, af_property_get), src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Make functions static. * src/base/ftobjs.c (ft_remove_renderer): Protect against library == NULL. (ft_property_do): Make function static. * src/base/ftrfork.c: Include `ftbase.h'. * src/sfnt/ttsbit.c (tt_face_load_sbix_image) [!FT_CONFIG_OPTION_USE_PNG], src/type1/t1gload.c (T1_Compute_Max_Advance): Avoid compiler warning. * src/truetype/ttinterp.c (TT_New_Context): Reduce scope of variable.
Chongyu Zhu 94c66944 2014-01-08T08:52:59 [arm] Fix Savannah bug #41138, part 2. * builds/unix/ftconfig.in (FT_MulFix_arm), include/config/ftconfig.h (FT_MulFix_arm), src/truetype/ttinterp.c (TT_MulFix14_arm): Fix preprocessor conditionals for `add.w'.
Werner Lemberg b337fa25 2013-12-21T19:33:15 Fix Savannah bug #40975 (sort of). * src/truetype/ttinterp.c (Ins_IP): Fix sign typo to make FreeType behave the same as the Windows TrueType engine for the invalid case.
Infinality 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.
Werner Lemberg 69d1a360 2013-12-10T10:12:27 [truetype] Fix scaling of vertical phantom points. * src/truetype/ttgload.c (load_truetype_glyph): Scale pp3.x and pp4.x also.
Werner Lemberg 7318b1aa 2013-12-10T09:40:36 Formatting.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg a44b784b 2013-12-02T09:52:38 Formatting.
Werner Lemberg 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.
Werner Lemberg 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.
Werner Lemberg 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'.
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 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 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 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 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 e921bdeb 2013-11-01T12:41:27 Comment fix.
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 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 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 a32682f1 2013-08-06T00:21:46 Fix gcc pragmas, part 2. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): `#pragma gcc diagnostic {push,pop}' has been introduced with gcc version 4.6.
Werner Lemberg 69e524d5 2013-08-05T23:38:32 Fix gcc pragmas. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): Older gcc versions don't accept diagnostic pragmas within a function body.
David Turner f66d48e9 2013-07-16T13:18:00 Add assembler code for TT_MulFix14 and TT_DotFix14. This patch provides slightly optimized versions for ARM, x86, and x86_64 CPUs if built with GCC.

Werner Lemberg 5ea06ce0 2013-03-17T08:14:46 Whitespace.
Werner Lemberg 89f50647 2013-03-14T17:50:49 */*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate. FT_Err_XXX and friends are no longer directly used in the source code.
Werner Lemberg e3c93015 2013-03-14T11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
Werner Lemberg 059bc335 2013-03-14T10:27:35 */*: Use `FT_THROW'. This is essentially a mechanical conversion, adding inclusion of `FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for stand-alone compiling modes of the rasterizer modules. To convert the remaining occurrences of FT_Err_XXX and friends it is necessary to rewrite the code. Note, however, that it doesn't harm if some cases are not handled since FT_THROW is a no-op.
Werner Lemberg a2c7eb18 2013-02-07T19:49:12 * src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables. BTW, Greg agrees that the OpenType specification is missing the list of GS variables which will always be reset to the default values after the `prep' table has been executed.
Werner Lemberg bfcc375b 2013-02-06T08:47:29 * src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points. Up to now, we simply took a snapshot of the Graphics State after the `prep' table has been executed, and right before a glyph's bytecode was run it got reloaded. However, as Greg Hitchcock has told us in private communication, reference points get reset to zero in the MS rasterizer and we follow in due course. While reasonable, this is undocumented behaviour. Most notably, this fixes the rendering of Arial's `x' glyph in subpixel hinting mode.
Werner Lemberg 00dfa330 2013-02-05T19:23:16 [truetype] A better fix for Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Implement identical behaviour to MS rasterizer if rp1 == rp2 (confirmed by Greg Hitchcock).
Werner Lemberg 40633205 2013-02-01T12:55:44 [truetype] Fix Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical to other interpreters if rp1 == rp2 (which is invalid).

Include FT_TRIGONOMETRY_H. * src/truetype/ttgload.c: Don't include FT_TRIGONOMETRY_H.
Werner Lemberg 87dc86d6 2013-01-24T08:39:43 [truetype] Revert change from 2013-01-22. FreeType's `height' value is the baseline-to-baseline distance... * src/truetype/ttobjs.c (tt_size_reset): Undo.
Alexei Podtelezhnikov b6de8e66 2013-01-23T23:31:41 [base, truetype] New internal FT_Hypot function. * include/freetype/fttrigon.h (FT_Hypot): Declare it. * src/base/fttrigon.c (FT_Hypot): Define it. * src/truetype/ttgload.c (TT_Process_Composite_Component): Use it instead of explicit expressions. * src/truetype/ttinterp.c (Current_Ratio, Normalize): Use it instead of TT_VecLen. (TT_VecLen): Removed.
Werner Lemberg e0469372 2013-01-22T11:07:07 [truetype] Fix font height. * src/truetype/ttobjs.c (tt_size_reset): The Windows rendering engine uses rounded values of the ascender and descender to compute the TrueType font height.
Werner Lemberg 71900980 2013-01-16T20:08:35 Minor.
David Turner 3a406127 2013-01-16T19:48:31 [truetype] Improve sub-pixel code. This patches fixes many issues with the ttsubpix implementation. 1. Data tables are defined, instead of declared, in the header, and thus copied into each source file that includes it. 2. These tables were defined as global, mutable, visible variables, and thus costing private RAM to every process that loads the library (> 50 KB / process, this is huge!). Additionally, this also made the library export the symbols completely needlessly. 3. Missing `sph_' and `SPH_' prefixes to some of the definitions. Note that this doesn't try to fix the incredibly inefficient storage format for the data tables used by the code. This one will require another pass in the future. * src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS): Renamed to... (SPH_MAX_NAME_SIZE, SPH_MAX_CLASS_MEMBERS): This. Update all users. (SPH_TweakRule, SPH_ScaleRule): Decorate with `const' where appropriate. (Font_Class): Rename to... (SPH_Font_Class): This. Decorate with `const' where appropriate. * src/truetype/ttsubpix.h (scale_test_tweak, sph_test_tweak): Decorate arguments with `const' where appropriate. Move font tweaking tables to... * src/truetype/ttsubpic.c: This file and decorate them with `static' and `const' where appropriate. (X_SCALING_Rules, X_SCALING_RULES_SIZE): Renamed to... (spu_X_SCALING_Rules, SPH_X_SCALING_RULES_SIZE): This. Update all users.
Alexei Podtelezhnikov 0e0fdc5d 2013-01-12T23:05:55 [truetype] Improve accuracy of normalization of short vectors. Unit vector components are stored as 2.14 fixed-point numbers. In order to calculate all 14 bits accurately, a short vector to be normalized has to be upscaled to at least 14 bits before its length is calculated. This has been safe since accurate CORDIC algorithms were adopted. * src/truetype/ttinterp.c (Normalize): Scale short vectors by 0x4000.
Alexei Podtelezhnikov 081aba39 2013-01-12T22:36:37 [truetype] Kill very old vector normalization hacks. Back in the days, vector length calculations were not very accurate and the vector normalization function, Normalize, had to meticulously correct the errors for long vectors [commit b7ef2b096867]. It was no longer necessary after accurate CORDIC algorithms were adopted, but the code remained. It is time to kill it. * src/truetype/ttinterp.c (Normalize): Remove error compensation. (TT_VecLen): Remove any mention of old less accurate implementation.
Werner Lemberg 7d6dc907 2012-12-27T01:08:24 * src/truetype/ttgload.c (tt_loader_init): Add more tracing.

Werner Lemberg a9f6f85e 2012-12-17T09:08:09 Various compiler warning fixes. * include/freetype/internal/ftserv.h (FT_SERVICE_UNAVAILABLE): Use `logical not' operator instead of negation. The idea is that `~' returns exactly the data type enforced by the cast to a pointer (be it 32bit or 64bit or whatever), while a negative integer has not this flexibility. * src/cache/ftccmap.c (FTC_CMAP_UNKNOWN): Ditto. * src/truetype/ttgxvar.c (ALL_POINTS, TT_Get_MM_Var): Ditto. * src/type/t1load.c (T1_Get_MM_Var): Ditto.
