3e86711e | 2014-11-25 09:01:07 | [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. | |
|
6689a009 | 2014-11-25 08:53:09 | [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. | |
|
b24e8ba2 | 2014-11-25 08:30:49 | [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. | |
|
ef439fd2 | 2014-11-25 08:14:15 | [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. | |
|

|
f0292bb9 | 2014-11-24 10:51:21 | [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'. | |
|
eca0f067 | 2014-11-24 10:22:08 | [truetype] Fix Savannah bug #43679. * src/truetype/ttpload.c (tt_face_load_hdmx): Check minimum size of `record_size'. | |
 |
96341dc3 | 2014-11-24 09:53:07 | [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. | |
|
f70d9342 | 2014-11-24 09:31:32 | [sfnt] Fix Savannah bug #43672. * src/sfnt/ttkern.c (tt_face_load_kern): Use correct value for minimum table length test. | |
|
73be9f9a | 2014-11-24 07:30:05 | [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. | |
|
a7a4207d | 2014-11-24 06:44:45 | [docmaker] Formatting, copyright, improved documentation. * src/tools/docmaker/*: No code changes besides trivial modifications. | |
|
af834617 | 2014-11-22 13:29:10 | [bdf] Fix Savannah bug #43660. * src/bdf/bdflib.c (_bdf_parse_glyphs) <"ENDFONT">: Check `_BDF_GLYPH_BITS'. | |
|
42fcd669 | 2014-11-22 12:44:33 | [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. | |
|
3788187e | 2014-11-22 10:46:47 | [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. | |
|
5f201ab5 | 2014-11-22 09:16:39 | [cff] Fix Savannah bug #43658. * src/cff/cf2ft.c (cf2_builder_lineTo, cf2_builder_cubeTo): Handle return values of point allocation routines. | |
|
9bd20b73 | 2014-11-22 06:24:45 | [sfnt] Fix Savannah bug #43656. * src/sfnt/ttcmap.c (tt_cmap4_validate): Fix order of validity tests. | |
|
dd89710f | 2014-11-21 22:19:28 | [type1, type42] Fix Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Fix boundary testing. | |
|
b1fc00d5 | 2014-11-21 12:06:40 | * src/pcf/pcfread.c (pcf_get_metrics): Sanitize invalid metrics. | |
|
23c093fc | 2014-11-21 08:41:39 | Minor. | |
|

|
644d6fab | 2014-11-21 07:28:50 | * src/base/ftbitmap.c (FT_Bitmap_Convert): Improve. This commit completes argument checks and adds support for different flow directions. | |
|
6de76174 | 2014-11-21 06:05:49 | * src/base/ftbitmap.c (FT_Bitmap_Copy): Improve. This commit adds argument checks and support for different flow directions. | |
|
1e6e1b83 | 2014-11-20 21:07:56 | * src/base/ftbitmap.c (FT_Bitmap_New): Check argument. | |
|
b3500af7 | 2014-11-19 21:28:21 | 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. | |
|
df485774 | 2014-11-19 21:21:23 | 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. | |
|
d6061212 | 2014-11-19 21:13:23 | Minor code improvement in `FT_Bitmap_Embolden'. * src/base/ftbitmap.c (FT_Bitmap_Embolden) <FT_PIXEL_MODE_GRAY[24]>: Fix thinko. | |
|
8d05486e | 2014-11-19 21:07:59 | Minor documentation improvements and whitespace. | |
 |
237c0abf | 2014-11-19 22:10:29 | Trailing space. | |
|
f841ad3e | 2014-11-19 21:19:06 | * src/base/fttrigon.c: Use dedicated `FT_Angle' for arctan table. | |
|

|
257c270b | 2014-11-12 21:42:13 | [sfnt] Fix Savannah bug #43591. * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Protect against addition and multiplication overflow. | |
|
677ddf4f | 2014-11-12 21:26:44 | [sfnt] Fix Savannah bug #43590. * src/sfnt/ttload.c (check_table_dir, tt_face_load_font_dir): Protect against addition overflow. | |
|
f46add13 | 2014-11-12 21:06:08 | [sfnt] Fix Savannah bug #43589. * src/sfnt/sfobjs.c (woff_open_font): Protect against addition overflow. | |
|
602040b1 | 2014-11-12 20:51:20 | [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. | |
|
2e73a1b4 | 2014-11-09 23:22:43 | [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. | |
|
0e73d218 | 2014-11-09 01:27:38 | * 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>. | |
|
2c4832d3 | 2014-11-07 07:42:33 | 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. | |
|
ef1eba75 | 2014-11-06 23:25:05 | Fix Savannah bug #43548. * src/pcf/pcfread (pcf_get_encodings): Add sanity checks for row and column values. | |
|
0e2f5d51 | 2014-11-06 22:32:46 | Fix Savannah bug #43547. * src/pcf/pcfread.c (pcf_read_TOC): Check `size' and `offset' values. | |
|
f49a100a | 2014-11-06 13:30:28 | * src/pcf/pcfread.c (pcf_read_TOC): Avoid memory leak. | |
 |
facfc79a | 2014-11-03 07:24:59 | * src/truetype/ttsubpix.c (COMPATIBILITY_MODE_Rules): Updated. The previous commit deteriorates rendering of DejaVu and similar fonts; this gets compensated with this rule. | |
|
706f752b | 2014-11-03 07:20:57 | * 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. | |
|
525d4876 | 2014-10-31 22:12:37 | [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code. | |
|
e1efe0a2 | 2014-10-31 00:07:14 | [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. | |
|
c7fd9356 | 2014-10-30 22:43:01 | [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. | |
|
465ab995 | 2014-10-29 23:45:23 | [smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code. | |
|
74916997 | 2014-10-29 22:24:24 | 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. | |
|
d8632a84 | 2014-10-25 06:28:18 | Improve comments, remove dead code. | |
|
fe15152c | 2014-10-25 05:56:59 | [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. | |
|
aba0f498 | 2014-10-24 23:50:57 | 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. | |
|
dd570e99 | 2014-10-23 19:57:37 | [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. | |
|
cc7bb80b | 2014-10-20 08:35:50 | [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. | |
|
118e651b | 2014-10-19 23:31:08 | [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. | |
|
d4aabda3 | 2014-10-18 10:10:04 | [truetype] Unwrap engine compensation settings. * src/truetype/ttobjs.c (tt_size_init_bytecode): Updated. | |
|
c9c33f20 | 2014-10-18 11:01:14 | [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. | |
|
1a1750fb | 2014-10-16 22:54:01 | [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. | |
|
03987bfd | 2014-10-16 07:19:46 | 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. | |
|
7e83f068 | 2014-10-14 23:03:56 | [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. | |
|
8f17809b | 2014-10-14 08:28:09 | [autofit] Adjust Devenagari character range. * src/autofit/afranges.c (af_deva_uniranges): Omit characters that are common to all other Indic scripts. | |
|
1ca5fa15 | 2014-10-12 08:31:32 | [sfnt] Fix Savannah bug #43392. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Don't let vertical metrics uninitialized. | |
|
673a28ef | 2014-10-11 14:40:51 | [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. | |
|
40dac113 | 2014-10-09 00:58:14 | [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. | |
|
2ffcf17e | 2014-10-08 22:01:08 | [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. | |
|
7abdb8cc | 2014-10-02 23:13:33 | [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. | |

(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'. | |
 |
1ec98b29 | 2014-08-31 08:47:11 | 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. | |
