(ft_var_load_avar): Check `pairCount' against table length. (ft_var_load_gvar): Check `globalCoordCount' and `glyphCount' against table length. (tt_face_vary_cvt): Check `tupleCount' and `offsetToData'. Fix trace. (TT_Vary_Apply_Glyph_Deltas): Fix trace. Free `sharedpoints' to avoid memory leak.
Werner Lemberg c220d8b4 2015-10-10T08:13:04 [truetype] Better protection against malformed GX data (#46166). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Correctly handle empty `localpoints' array.
Werner Lemberg 8651f37a 2015-09-30T10:26:10 [truetype] Adjust number of glyphs for malformed `loca' tables. * src/truetype/ttpload.c (tt_face_load_loca): Implement it.

(TT_LoaderRec): Switch to appropriate types for `face' and `size'. * src/truetype/ttgload.c: Remove corresponding type casts. * src/truetype/ttsubpix.c: Ditto.
Werner Lemberg 8dfc7601 2015-08-03T12:23:30 * src/truetype/ttgload.c (load_truetype_glyph) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Fix crash for composite glyphs having a depth greater than 1.
Werner Lemberg 70e9d815 2015-08-02T09:42:12 Fix more invalid left-shifts. * src/pfr/pfrgload.c (pfr_glyph_load_compound): Use multiplication, not left-shift. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Use multiplication, not left-shift.
Werner Lemberg 6343ba22 2015-08-01T07:53:48 Fix some bugs found by clang's `-fsanitize=undefined' (#45661). * src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Only accept positive values from header. Check overflow. * src/base/ftoutln.c (SCALED): Correctly handle left-shift of negative values. * src/bdf/bdf.h (_bdf_glyph_modified, _bdf_set_glyph_modified, _bdf_clear_glyph_modified): Use unsigned long constant. * src/bdf/bdfdrivr.c (BDF_Size_Select, BDF_Glyph_Load): Don't left-shift values that can be negative. * src/pcf/pcfdrivr.c (PCF_Size_Select, PCF_Glyph_Load): Don't left-shift values that can be negative. * src/raster/ftraster.c (SCALED): Correctly handle left-shift of negative values. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Don't left-shift values that can be negative. * src/truetype/ttgload.c (TT_Load_Composite_Glyph, compute_glyph_metrics, load_sbit_image): Don't left-shift values that can be negative.
Werner Lemberg f9be567f 2015-07-09T15:10:31 Better support of user-supplied C++ namespaces. See http://lists.nongnu.org/archive/html/freetype-devel/2015-07/msg00008.html for a rationale. * src/autofit/afpic.h, src/base/basepic.h, src/cff/cffpic.h, src/pshinter/pshpic.h, src/psnames/pspic.h, src/raster/rastpic.h, src/sfnt/sfntpic.h, src/smooth/ftspic.h, src/truetype/ttpic.h (FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose header files that contain FT_{BEGIN,END}_HEADER macros by themselves. * src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include FT_CONFIG_STANDARD_LIBRARY_H earlier. * src/truetype/ttpic.h: Include FT_INTERNL_PIC_H.
Werner Lemberg 6f918969 2015-07-04T11:35:28 Minor documentation issue.
Werner Lemberg eb1bba9b 2015-06-30T09:46:39 Fix some clang compiler warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY), src/cff/cf2intrp.c (cf2_interpT2CharString), src/truetype/ttgload.c (load_truetype_glyph), src/truetype/ttgxvar.c (tt_handle_deltas), src/truetype/ttinterp.c (Ins_INSTCTRL): Fix signedness issues.
Alexei Podtelezhnikov 5aaabb44 2015-06-29T22:46:54 [truetype] Speed up bytecode interpreter. * src/truetype/ttinterp.c (Normalize): Use `FT_Vector_NormLen'.
Werner Lemberg 31d97df9 2015-06-21T19:12:12 Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.
Werner Lemberg e1862306 2015-06-07T16:11:18 * Version 2.6 released. ======================= Tag sources with `VER-2-6'. * docs/VERSION.DLL: Update documentation and bump version number to 2.6. * 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/2.5.5/2.6/, s/255/26/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 6. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 18:0:12. * CMakeLists.txt (VERSION_MINOR): Set to 0. (VERSION_PATCH): Set to 6. * src/autofit/afmodule.c [!FT_MAKE_OPTION_SINGLE_OBJECT]: Add declarations for dumping functions. * src/truetype/ttinterp.c (TT_New_Context): Pacify compiler. * builds/toplevel.mk: Use `freetype.mk's code to compute the version string. Don't include a zero patch level in version string. * builds/freetype.mk: Remove code for computing the version string.
Werner Lemberg 75534a04 2015-06-03T00:54:09 [truetype] Fix memory leak. Problem reported by Grissiom <chaos.proton@gmail.com>; in http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html there is an example code to trigger the bug. * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size' data before allocating again. Bug most probably introduced four years ago in version 2.4.3.
Werner Lemberg 54d04286 2015-06-01T12:12:06 [truetype] While tracing opcodes, show code position and stack. * src/truetype/ttinterp.c: Change all existing TRACE7 calls to TRACE6. (opcode_name): Add string lengths. (TT_RunIns): Implement display of code position and stack.
Werner Lemberg e9df4e47 2015-05-31T12:21:34 [truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated.
Werner Lemberg 9845c1d4 2015-05-31T11:57:31 [truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
Werner Lemberg cdee7d14 2015-05-31T11:54:42 [truetype] Add tracing information to GX code. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend, TT_Set_Var_Design, tt_face_vary_cvt): Do it.
Werner Lemberg a678560d 2015-05-28T17:31:15 Minor.
Werner Lemberg a5e1f6f3 2015-05-24T23:29:23 [truetype] Fix commit from 2015-05-22. * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'. Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
Werner Lemberg 7f099482 2015-05-24T09:50:24 [truetype] Fix return values of GETINFO bytecode instruction. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `vertical_lcd' and `gray_cleartype'. * src/truetype/ttgload.c (tt_loader_init): Initialize new fields. Change `symmetrical smoothing' to TRUE, since FreeType produces exactly this. * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit values for symmetrical smoothing, namely 11/18. Handle bits for vertical LCD subpixels (8/15) and Gray ClearType (12/19).
Werner Lemberg bb435da2 2015-05-23T07:21:25 [truetype] Minor. * src/truetype/ttinterp.h (TT_ExecContext): s/subpixel/subpixel_hinting. * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
Werner Lemberg c61cad86 2015-05-22T22:02:15 [truetype] Support selector index 3 of the INSTCTRL instruction. This flag activates `native ClearType hinting', disabling backwards compatibility mode as described in Greg Hitchcocks whitepaper. In other words, it enables unrestricted functionality of all TrueType instructions in ClearType. * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks' unconditionally. (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of `GS.instruct_control' is active. * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3. (Ins_GETINFO): Updated. * docs/CHANGES: Document it.
Werner Lemberg 790b8dfb 2015-05-20T12:33:40 [truetype] Minor.
Werner Lemberg 0a6b6ff7 2015-05-17T22:54:48 [truetype] Fix loading of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the ARGS_ARE_XY_VALUES flag is not set, handle argument values as unsigned. I trust `ttx' (which has exactly such code) that it does the right thing here... The reason that noone has ever noticed this bug is probably the fact that point-aligned subglyphs are rare, as are subglyphs with a number of points in the range [128;255], which is quite large (or even in the range [32768;65535], which is extremely unlikely).
Alexei Podtelezhnikov 40623a1f 2015-04-27T22:27:00 [truetype] Speed up IUP. * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial snapping to the same position from true interpolation.
Alexei Podtelezhnikov adb08efc 2015-04-11T23:54:19 [bdf,pcf,truetype] NULL.
Werner Lemberg 10e2bb8b 2015-03-29T13:32:47 [type1, truetype] Make the MM API more flexible w.r.t. `num_coords'. This commit allows `num_coords' to be larger or smaller than the number of available axes while selecting a design instance, either ignoring excess data or using defaults if data is missing. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Implement it. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design, T1_Set_Var_Design): Ditto.
Werner Lemberg 6cc425db 2015-03-21T06:51:07 [truetype] Improve `gvar' handling. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Correctly handle single-element runs. Cf. glyph `Q' in Skia.ttf with weights larger than the default.
Werner Lemberg a451638e 2015-03-11T08:09:13 Rename `svxf86nm.h' to `svfntfmt.h'; update related symbols. * include/internal/ftserv.h (FT_SERVICE_XFREE86_NAME_H): Renamed to... (FT_SERVICE_FONT_FORMAT_H): This. * include/internal/services/svfntfmt.h (FT_XF86_FORMAT_*): Renamed to ... (FT_FONT_FORMAT_*): This. src/base/ftfntfmt.c, src/bdf/bdfdrivr.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: Updated.
Werner Lemberg 0aa36160 2015-03-08T22:50:37 Formatting, whitespace, addition of some comments.
Werner Lemberg 328b7923 2015-03-04T08:40:23 [truetype] Some fixes and code refactoring in `ttgxvar.c'. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix return value of `point_cnt' if two bytes are read. Use a more vertical coding style. (ft_var_readpackeddeltas): Use FT_UInt for `delta_cnt' parameter. Use a more vertical coding style.
Werner Lemberg 851e8151 2015-03-01T19:27:09 Various compiler warning fixes for `make multi'. * src/autofit/afcjk.c (af_cjk_hints_compute_blue_edges), src/autofit/aflatin.c (af_latin_hint_compute_blue_edges, af_latin_hint_edges), src/autofit/aflatin2.c (af_latin2_hints_compute_blue_edges, af_latin2_hint_edges): Declare as `static'. * src/cache/ftccmap.c (FTC_CMAP_QUERY_HASH, FTC_CMAP_NODE_HASH): Removed.

(T1_FIELD_COUNT): Removed. Unused. * src/type1/t1parse.h (T1_Done_Table): Removed. Unused. * src/type42/t42parse.c (T1_Done_Table): Removed. Unused.
Werner Lemberg 3a1df3e1 2015-02-19T15:42:48 * src/truetype/ttgxvar.c (TT_Get_MM_Var): Ignore `countSizePairs'. This is hard-coded to value 2 in `fvar' version 1.0 (and no newer version exists), but some fonts set it incorrectly. Problem reported by Adam Twardoch <adam@fontlab.com>.
Werner Lemberg 1f7a4e1f 2015-02-17T10:17:56 [truetype] Finish compiler warning fixes for signedness issues. * src/truetype/ttgxvar.c, src/truetype/ttsubpix.c, src/truetype/ttsubpix.h: Apply.

(CONST_FT_RFORK_RULE_ARRAY_BEGIN): Add `static' keyword. * include/internal/ftstream.h (FT_Stream_Pos): Return `FT_ULong'. * src/base/ftoutln.c, src/base/ftrfork.c, src/base/ftstream.c: Signedess fixes.
Jon Anderson 416d8796 2015-02-06T10:16:45 [truetype] Fix regression in the incremental glyph loader. * src/truetype/ttgload.c (load_truetype_glyph): For incremental fonts, the glyph index may be greater than the number of glyphs indicated, so guard the check with a preprocessor conditional.
Werner Lemberg f57fc59e 2015-01-17T20:41:43 Run `src/tools/update-copyright'.
Werner Lemberg f796cf6c 2015-01-17T20:11:10 Normalize copyright notice format.
Behdad Esfahbod 531d463a 2015-01-14T17:46:55 [truetype] Allocate TT_ExecContext in TT_Size instead of TT_Driver. Previously the code had stipulation for using a per-TT_Size exec context if `size->debug' was true. But there was no way that `size->debug' could *ever* be true. As such, the code was always using the singleton `TT_ExecContext' that was stored in `TT_Driver'. This was, clearly, not threadsafe. With this patch, loading glyphs from different faces from different threads doesn't crash in the bytecode loader code. * src/truetype/ttobjs.h (TT_SizeRec): Remove `debug' member. (TT_DriverRec): Remove `context' member. * src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Remove `TT_ExecContext' code related to a global `TT_Driver' object. (tt_driver_done): Don't remove `TT_ExecContext' object here but ... (tt_size_done_bytecode): ... here. (tt_driver_init): Don't create `TT_ExecContext' object here but ... (tt_size_init_bytecode): ... here, only on demand. * src/truetype/ttinterp.c (TT_Run_Context): Remove defunct debug code. (TT_New_Context): Remove `TT_ExecContext' code related to a global `TT_Driver' object. * src/truetype/ttinterp.h: Updated. * src/truetype/ttgload.c (TT_Hint_Glyph, tt_loader_init): Updated.
Werner Lemberg 36d03c9f 2015-01-12T11:26:30 Fix Savannah bug #43976. Assure that FreeType's internal include directories are found before `CPPFLAGS' (which might be set by the user in the environment), and `CPPFLAGS' before `CFLAGS'. * builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'. (FT_COMPILE): Make this a special variable for compiling only the files handled in `freetype.mk'. (.c.$O): Removed, unused. * src/*/rules.mk (*_COMPILE): Fix order of include directories.
Werner Lemberg 2af74c9b 2015-01-11T10:08:09 [truetype] Better grouping of functions in `ttinterp.c'. No code change.

Werner Lemberg 7e1db6d4 2015-01-11T00:56:55 Formatting, typos.
Werner Lemberg eb341368 2015-01-11T00:23:27 [truetype] More macro expansions. Based on a patch from Behdad. * src/truetype/ttinterp.c (DO_*): Expand macros into corresponding `Ins_*' functions. (TT_RunIns): Replace `DO_*' macros with `Ins_*' function calls. (ARRAY_BOUND_ERROR): Remove second definition, which is no longer needed. (Ins_SVTCA, Ins_SPVTCA, Ins_SFVTCA): Replaced with...

Behdad suggested this code simplification, and nobody objected... * include/config/ftoption.h, devel/ftoption.h (TT_CONFIG_OPTION_INTERPRETER_SWITCH): Remove. * src/truetype/ttinterp.c [TT_CONFIG_OPTION_INTERPRETER_SWITCH]: Remove related code. (ARRAY_BOUND_ERROR): Use do-while loop.
Werner Lemberg 6cc1f123 2015-01-10T21:56:59 [truetype] More macro expansions. * src/truetype/ttinterp.c, src/truetype/ttinterp.h (EXEC_ARG_, EXEC_ARG): Remove by replacing with expansion.
Werner Lemberg 24681455 2015-01-10T21:53:48 [truetype] More macro expansions. Based on a patch from Behdad. * src/truetype/ttinterp.c (SKIP_Code, GET_ShortIns, NORMalize, SET_SuperRound, ROUND_None, INS_Goto_CodeRange, CUR_Func_move, CUR_Func_move_orig, CUR_Func_round, CUR_Func_cur_ppem, CUR_Func_read_cvt, CUR_Func_write_cvt, CUR_Func_move_cvt, CURRENT_Ratio, INS_SxVTL, COMPUTE_Funcs, COMPUTE_Round, COMPUTE_Point_Displacement, MOVE_Zp2_Point): Remove by replacing with expansion.

Werner Lemberg 0098d550 2014-12-07T11:03:57 Uppercase all hex digits for orthogonality.
Werner Lemberg 9870d6da 2014-12-07T09:40:47 */*: Decorate hex constants with `U' and `L' where appropriate.
Werner Lemberg 66883b58 2014-12-07T09:17:06 [truetype] Prevent memory leak for buggy fonts. * src/truetype/ttobjs.c (tt_size_done): Unconditionally call `tt_size_done_bytecode'.

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 04edbbda 2014-11-25T10:21:13 */*: s/Invalid_Argument/Invalid_Face_Handle/ where appropriate.
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'.

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 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.

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.
