Werner Lemberg 3e86711e 2014-11-25T09:01:07 [Savannah bug #43682] Adjust some renderer callbacks. * src/raster/ftraster.c (ft_black_set_mode): Change return type to `int' to stay in sync with `FT_Renderer_SetModeFunc' prototype. * src/smooth/ftgrays.c (gray_raster_set_mode): New dummy function for orthogonality. (ft_grays_raster): Use it.
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 f0292bb9 2014-11-24T10:51:21 [sfnt] Fix Savannah bug #43680. This adds an additional constraint to make the fix from 2013-01-25 really work. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image) <index_format==4>: Check `p' before `num_glyphs'.
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'.
Jarkko Pöyry 96341dc3 2014-11-24T09:53:07 [cff, pfr, psaux, winfonts] Fix Savannah bug #43676. Don't cast cmap init function pointers to an incompatible type. Without this patch, the number of parameters between declaration and the real signature differs. Calling such a function results in undefined behavior. ISO/IEC 9899:TC3 (Committee Draft September 7, 2007) 6.5.2.2 Function calls 9 If the function is defined with a type that is not compatible with the type (of the expression) pointed to by the expression that denotes the called function, the behavior is undefined. On certain platforms (c -> js with emscripten) this causes termination of execution or invalid calls because in the emscripten implementation, function pointers of different types are stored in different pointer arrays. Incorrect pointer type here results in indexing of an incorrect array. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init), src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c t1_cmap_standard_init, t1_cmap_expert_init, t1_cmap_custom_init, t1_cmap_unicode_init), src/winfonts/winfnt.c (fnt_cmap_init): Fix signature.
Werner Lemberg f70d9342 2014-11-24T09:31:32 [sfnt] Fix Savannah bug #43672. * src/sfnt/ttkern.c (tt_face_load_kern): Use correct value for minimum table length test.
Werner Lemberg 73be9f9a 2014-11-24T07:30:05 [type1, type42] Another fix for Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Add another boundary testing.
Werner Lemberg a7a4207d 2014-11-24T06:44:45 [docmaker] Formatting, copyright, improved documentation. * src/tools/docmaker/*: No code changes besides trivial modifications.
Werner Lemberg af834617 2014-11-22T13:29:10 [bdf] Fix Savannah bug #43660. * src/bdf/bdflib.c (_bdf_parse_glyphs) <"ENDFONT">: Check `_BDF_GLYPH_BITS'.
Werner Lemberg 42fcd669 2014-11-22T12:44:33 [type42] Allow only embedded TrueType fonts. This is a follow-up to Savannah bug #43659. * src/type42/t42objs.c (T42_Face_Init): Exclusively use the `truetype' font driver for loading the font contained in the `sfnts' array.
Werner Lemberg 3788187e 2014-11-22T10:46:47 [type42] Fix Savannah bug #43659. * src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'. * src/type42/t42parse.c (t42_parse_sfnts): Always set `face->ttf_size' directly. This ensures a correct stream size in the call to `FT_Open_Face', which follows after parsing, even for buggy input data. Fix error messages.
Werner Lemberg 5f201ab5 2014-11-22T09:16:39 [cff] Fix Savannah bug #43658. * src/cff/cf2ft.c (cf2_builder_lineTo, cf2_builder_cubeTo): Handle return values of point allocation routines.
Werner Lemberg 9bd20b73 2014-11-22T06:24:45 [sfnt] Fix Savannah bug #43656. * src/sfnt/ttcmap.c (tt_cmap4_validate): Fix order of validity tests.
Werner Lemberg dd89710f 2014-11-21T22:19:28 [type1, type42] Fix Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Fix boundary testing.

Werner Lemberg b3500af7 2014-11-19T21:28:21 Change some fields in `FT_Bitmap' to unsigned type. This doesn't break ABI. * include/ftimage.h (FT_Bitmap): Make `rows', `width', `num_grays', `pixel_mode', and `palette_mode' unsigned types. * src/base/ftbitmap.c: Updated. (FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated.
Werner Lemberg df485774 2014-11-19T21:21:23 Make `FT_Bitmap_Convert' correctly handle negative `pitch' values. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always use positive value for the pitch while copying data. Correctly set pitch sign in target bitmap.
Werner Lemberg d6061212 2014-11-19T21:13:23 Minor code improvement in `FT_Bitmap_Embolden'. * src/base/ftbitmap.c (FT_Bitmap_Embolden) <FT_PIXEL_MODE_GRAY[24]>: Fix thinko.
Werner Lemberg 8d05486e 2014-11-19T21:07:59 Minor documentation improvements and whitespace.

Werner Lemberg f46add13 2014-11-12T21:06:08 [sfnt] Fix Savannah bug #43589. * src/sfnt/sfobjs.c (woff_open_font): Protect against addition overflow.
Werner Lemberg 602040b1 2014-11-12T20:51:20 [sfnt] Fix Savannah bug #43588. * src/sfnt/ttcmap.c (tt_cmap8_validate, tt_cmap10_validate, tt_cmap12_validate, tt_cmap13_validate, tt_cmap14_validate): Protect against overflow in additions and multiplications.
Alexei Podtelezhnikov 2e73a1b4 2014-11-09T23:22:43 [base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justifed by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept. (ft_trig_pseudo_polarize): Decrease `theta' padding.
Werner Lemberg 0e73d218 2014-11-09T01:27:38 * src/base/ftstroke.c (ft_stroker_inside): Fix border intersections. One more place to check whether `radius' is zero. Problem reported by Marco Wertz <marco.wertz@gmx.de>.
Werner Lemberg 2c4832d3 2014-11-07T07:42:33 Fix Savannah bug #43535. * src/bdf/bdflib.c (_bdf_strncmp): New macro that checks one character more than `strncmp'. s/ft_strncmp/_bdf_strncmp/ everywhere.
Werner Lemberg ef1eba75 2014-11-06T23:25:05 Fix Savannah bug #43548. * src/pcf/pcfread (pcf_get_encodings): Add sanity checks for row and column values.
Werner Lemberg 0e2f5d51 2014-11-06T22:32:46 Fix Savannah bug #43547. * src/pcf/pcfread.c (pcf_read_TOC): Check `size' and `offset' values.
Werner Lemberg f49a100a 2014-11-06T13:30:28 * src/pcf/pcfread.c (pcf_read_TOC): Avoid memory leak.
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 525d4876 2014-10-31T22:12:37 [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code.
Alexei Podtelezhnikov e1efe0a2 2014-10-31T00:07:14 [smooth] Reduce outline translations during rendering. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Translate origin virtually by modifying cbox, actually translate outline if cumulative shift is not zero.
Alexei Podtelezhnikov c7fd9356 2014-10-30T22:43:01 [smooth] Fix Savannah bug #35604 (cont'd). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove checks and casts that became unnecessary after the variable type upgrades.
Alexei Podtelezhnikov 465ab995 2014-10-29T23:45:23 [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code.
Alexei Podtelezhnikov 74916997 2014-10-29T22:24:24 Unify hypotenuse approximations. * include/internal/ftcalc.h (FT_HYPOT): Move macro from here... * include/internal/ftobjs.h: ... to here, next to required `FT_ABS'. * src/smooth/ftgrays.c (gray_render_cubic): Use it here.
Werner Lemberg d8632a84 2014-10-25T06:28:18 Improve comments, remove dead code.
Werner Lemberg fe15152c 2014-10-25T05:56:59 [cff] Test valid darkening parameter macros in `ftoption.h'. We no longer need an otherwise unused typedef that can cause a gcc warning. Problem reported by Alexei. * src/cff/cffobjs.c (cff_driver_init): Use `CFF_CONFIG_OPTION_DARKENING_PARAMETER_XXX' macros directly. (SET_DARKENING_PARAMETERS): Removed. Compile time tests are now ... * devel/ftoption.h, include/config/ftoption.h: ... here.
Alexei Podtelezhnikov aba0f498 2014-10-24T23:50:57 Improve flat corner definition. * include/internal/ftcalc.h (FT_HYPOT): Macro to approximate Euclidean distance with the alpha max plus beta min algorithm. * src/base/ftcalc.c (ft_corner_is_flat): Use it instead of Taxicab metric.
Werner Lemberg dd570e99 2014-10-23T19:57:37 [cff] Work around bug in preprocessor of MSVC 2010. We have been hit by https://connect.microsoft.com/VisualStudio/feedback/details/718976/msvc-pr * devel/ftoption.h, include/config/ftoption.h: Replace `CFF_CONFIG_OPTION_DARKENING_PARAMETERS' with eight macros `CFF_CONFIG_OPTION_DARKENING_PARAMETER_{X,Y}{1,2,3,4}'. * src/cff/cffobjs.c (SET_DARKENING_PARAMETERS): Removed. We no longer need double expansion. (SET_DARKENING_PARAMETERS_0): Renamed to ... (SET_DARKENING_PARAMETERS): ... this. Update call.
Werner Lemberg cc7bb80b 2014-10-20T08:35:50 [sbit] Minor fixes. * src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]: Accept overlay format also, but emit warning message in that case. (tt_sbit_decoder_load_metrics): Add missing newline to error message. (tt_sbit_load_sbix_image): Add `rgbl' graphic type (as used on iOS 7.1) to the list of unsupported formats.
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 c9c33f20 2014-10-18T11:01:14 [autofit] Add blue-zone support for Telugu. This essentially moves the Telugu script from the `Indic' hinter to the `Latin' hinter. Note that this is a first shot and quite certainly needs refinements. * src/autofit/afblue.dat: Add blue zone data for Telugu. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afscript.h: Add Telugu standard characters and move data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afranges.c: Move Telugu data out of AF_CONFIG_OPTION_INDIC block. * src/autofit/afstyles.h: Update Telugu data; in particular, use AF_WRITING_SYSTEM_LATIN.
Werner Lemberg 1a1750fb 2014-10-16T22:54:01 [cff] Add `CFF_CONFIG_OPTION_DARKENING_PARAMETERS' config macro. * devel/ftoption.h, include/config/ftoption.h (CFF_CONFIG_OPTION_DARKENING_PARAMETERS): New macro. * src/cff/cffobjs.c (SET_DARKENING_PARAMETERS, SET_DARKENING_PARAMETERS_0): New macros. (cff_driver_init): Use new macros.
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.
Werner Lemberg 8f17809b 2014-10-14T08:28:09 [autofit] Adjust Devenagari character range. * src/autofit/afranges.c (af_deva_uniranges): Omit characters that are common to all other Indic scripts.
Werner Lemberg 1ca5fa15 2014-10-12T08:31:32 [sfnt] Fix Savannah bug #43392. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Don't let vertical metrics uninitialized.
Alexei Podtelezhnikov 673a28ef 2014-10-11T14:40:51 [base] Small bbox correction. * src/base/ftbbox.c (FT_Outline_Get_BBox): Start from nonsense bbox instead of initial point that could be `off' in conic outlines.
Alexei Podtelezhnikov 40dac113 2014-10-09T00:58:14 [base] Fix Savannah bug #43356. * src/base/ftbbox.c (BBox_Move_To, BBox_Conic_To): Update bbox in case of implicit `to'. (BBox_Line_To): New emitter that does not update bbox.
Alexei Podtelezhnikov 2ffcf17e 2014-10-08T22:01:08 [base] Introduce and use new macro `FT_UPDATE_BBOX' * src/base/ftbbox.c (FT_UPDATE_BBOX): New macro. (FT_Outline_Get_BBox): Use it here.
Alexei Podtelezhnikov 7abdb8cc 2014-10-02T23:13:33 [base] Significant optimization of `ft_div64by32' We shift as many bits as we can into the high register, perform 32-bit division with modulo there, then work through the remaining bits with long division. This optimization is especially noticeable for smaller dividends that barely use the high register. * src/base/ftcalc.c (ft_div64by32): Updated.
Werner Lemberg c0ce72a6 2014-10-02T06:44:43 Formatting.
Dave Arnold 537c55d3 2014-10-02T06:32:32 [cff] Fix Savannah bug #43271. * src/cff/cf2font.c (cf2_computeDarkening): Change overflow detection to use logarithms and clamp `scaledStem'.
Alexei Podtelezhnikov 74d0aad2 2014-10-01T23:27:15 * src/base/ftcalc.c: Remove miscellaneous type casts.
Alexei Podtelezhnikov 418e18f3 2014-10-01T22:36:40 [base] Use more common `FT_MSB' implementation with masks. * src/base/ftcalc.c (FT_MSB): Updated.

Alexei Podtelezhnikov 7f49111f 2014-09-25T22:54:38 [base] Avoid unnecessary long division. This applies to `FT_MulDiv' but not to `FT_DivFix', where overflows or lack thereof are predicted accurately. * src/base/ftcalc.c (ft_div64by32): Improve readability. (FT_MulDiv, FT_MulDiv_No_Round) [!FT_LONG64]: Use straight division when multiplication stayed within 32 bits.
Werner Lemberg 5b68e4fb 2014-09-24T19:06:13 [autofit] Minor clean-ups. * src/autofit/afhints.c (AF_FLAGS): Remove obsolete values. * src/autofit/afhints.c (af_glyph_hints_dump_points, af_glyph_hints_align_strong_points): Updated. * src/autofit/aflatin.c (af_latin_hints_link_segments, af_latin_hints_compute_segments), src/autofit/afcjk.c (af_cjk_hints_link_segments), src/autofit/aflatin2.c (af_latin2_hints_link_segments, af_latin2_hints_compute_segments): There are no longer fake segments since more than 10 years...
