89f50647 2013-03-14 17:50:49 */*: 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.
e3c93015 2013-03-14 11:21:17 */*: Use FT_Err_Ok only. This is a purely mechanical conversion.
059bc335 2013-03-14 10:27:35 */*: 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.
c58ce3be 2013-03-13 11:06:39 Introduce `FT_THROW' macro. The idea is to replace code like return FT_Err_Foo_Bar; or return CFF_Err_Foo_Bar; with return FT_THROW( Foo_Bar ); The FT_THROW macro has two functions: . It hides the module specific prefix. . In debug mode, it calls the empty function `FT_Throw' which can be thus used to set a breakpoint. * include/freetype/internal/ftdebug.h (FT_THROW): New macro. (FT_Throw): New prototype. * src/base/ftdebug.c (FT_Throw): New function.
dbc6e3f1 2013-03-12 11:42:20 Remove `FT_KEEP_ERR_PREFIX'. The idea is to always have FT_ERR_PREFIX available internally. * include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard undefinition of FT_ERR_PREFIX * src/gxvalid/gxverror.h, src/otvalid/otverror.h, src/sfnt/sferrors.h: Updated.
c879f245 2013-03-11 10:11:57 [gxvalid] Fix module error. * src/gxvalid/gxverror.h (FT_ERR_BASE): Define as FT_Mod_Err_GXvalid. * include/freetype/ftmoderr.h: Add module error for `GXvalid'.
d6bc524b 2013-03-11 09:50:53 Always use module related error codes. * src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c (T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use `FT_ERROR_BASE'. * src/type1/t1load.c (parse_encoding): Use T1_Err_Unknown_File_Format.
2d882540 2013-03-08 21:23:45 [cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also. * src/cff/cffgload.c (cff_slot_load): Implement it.
2ba18ba1 2013-02-22 23:58:57 [base] Fix commit ab02d9e8. * src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.
f9434dba 2013-02-19 21:27:18 [base] New bisecting BBox_Cubic_Check (disabled). * src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm for extremum search built around simple condition that defines which half contains the extremum.
0e536676 2013-02-18 20:41:56 [tools] Update BBox testing tool. * src/tools/test_bbox.c: Add another cubic outline with exact BBox. (REPEAT): Increase the number of benchmarking cycles. (profile_outline): Tweak output formatting.
a2c7eb18 2013-02-07 19:49:12 * 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.
bfcc375b 2013-02-06 08:47:29 * 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.
00dfa330 2013-02-05 19:23:16 [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).
0eb6316f 2013-02-01 20:24:00 [pcf] Streamline parsing of PCF encoding table. * src/pcf/pcfread.c (pcf_get_encodings): Use simpler double for-loop. Reallocate array instead of using temporary storage.
30f1e6ca 2013-02-01 14:50:08 Fix Savannah bug #38221. This complements commit 83c0ebab. * src/base/ftcalc.c (FT_MulDiv_No_Round): Don't enclose with `TT_USE_BYTECODE_INTERPRETER'.
40633205 2013-02-01 12:55:44 [truetype] Fix Savannah bug #38211. * src/truetype/ttinterp.c (Ins_IP): Make FreeType behave identical to other interpreters if rp1 == rp2 (which is invalid).

c574d72c 2013-01-26 17:40:44 [truetype] Minor formatting fix.
97ba5109 2013-01-26 17:05:40 [truetype] Fix rasterizer_version logic in sph.

610ee58e 2013-01-25 23:33:00 [base] Fix broken emboldening at small sizes. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Do not attempt to normalize zero-length vectors.
f41ee054 2013-01-25 16:41:24 Fix Savannah bug #38167. This fixes commit 83c0ebab from 2012-06-27. * src/truetype/ttinterp.h: s/TT_CONFIG_OPTION_BYTECODE_INTERPRETER/TT_USE_BYTECODE_INTERPRETER/.
ba931be2 2013-01-25 00:57:09 [sfnt] Fix broken pointer overflow checks. Many compilers such as gcc and clang optimize away pointer overflow checks `p + n < p', because pointer overflow is undefined behavior. Use a safe form `n > p_limit - p' instead. Also avoid possible integer overflow issues, for example, using `num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2' given a large `num_glyphs'. * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Implement it.
817caa9f 2013-01-25 00:40:56 Fix `make multi' * src/base/ftoutln.c, src/base/fttrigon.c: Include FT_INTERNAL_CALC_H.
72447195 2013-01-25 00:36:35 [truetype] Fix C++ compilation. * src/truetype/ttsubpix.h: Updated.

Include FT_TRIGONOMETRY_H. * src/truetype/ttgload.c: Don't include FT_TRIGONOMETRY_H.
87dc86d6 2013-01-24 08:39:43 [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.
b6de8e66 2013-01-23 23:31:41 [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.
dcc0d070 2013-01-23 23:09:59 Typo.
da11e5e7 2013-01-23 20:11:40 [base] Fix integer overflow. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Normalize incoming and outgoing vectors and use fixed point arithmetic.
e1a2ac19 2013-01-23 19:51:28 [base] Fix integer overflow. * src/base/ftoutln.c (FT_Outline_Get_Orientation): Scale the coordinates down to avoid overflow.
869fb8c4 2013-01-23 19:43:28 [base] Split out MSB function. * src/base/fttrigon.c (ft_trig_prenorm): Borrow from here. * include/freetype/internal/ftcalc.h (FT_MSB): Declare here. * src/base/ftcalc.c (FT_MSB): Define here.
e0469372 2013-01-22 11:07:07 [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.
71900980 2013-01-16 20:08:35 Minor.
cd3f871e 2013-01-16 19:56:08 [sfnt] Fix optimized sbit loader. It was not taking bit_depth into consideration when blitting! * src/sfnt/ttsbit0.c (tt_sbit_decoder_load_byte_aligned, * tt_sbit_decoder_load_bit_aligned): Handle bit depth.
3a406127 2013-01-16 19:48:31 [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.
0e0fdc5d 2013-01-12 23:05:55 [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.
081aba39 2013-01-12 22:36:37 [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.
a692170a 2013-01-12 19:17:05 Call it fixed-point.
53c0cb59 2013-01-11 08:29:22 Typos, whitespace.
ad9d5c97 2013-01-10 22:29:07 [base] Update the overflow protection bit. The recent optimizations of CORDIC iterations drastically reduce the expansion factor. The vector components with MSB of 29 are now safe from overflow. * src/base/fttrigon.c (FT_TRIG_SAFE_MSB): New macro. (ft_trig_prenorm): Use it and remove dead code.
4412e74d 2013-01-10 20:16:20 Minor comment improvements.
6b83a367 2013-01-09 00:25:32 [base, pshinter] Use FT_ABS, FT_MIN, and FT_MAX for readability. * src/base/ftbbox.c: Updated. * src/base/ftobjs.c: Updated. * src/base/fttrigon.c: Updated. * src/pshinter/pshalgo.c: Updated. * src/pshinter/pshrec.c: Updated.
09dbb059 2013-01-08 23:29:44 [base] Clean up trigonometric core. * src/base/fttrigon.c: Document the algorithm in a large comment. (FT_TRIG_COSCALE): Remove macro. (FT_Tan: Use `FT_TRIG_SCALE' instead. (FT_Cos, FT_Vector_Unit): Ditto and round the return values.
5dd9657f 2013-01-02 23:45:14 [base] Use rounding in CORDIC iterations. * src/base/fttrigon.c (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Improve accuracy by rounding.
b4ac30b0 2013-01-02 22:21:37 [base] Reduce trigonometric algorithms. After we get within 45 degrees by means of true 90-degree rotations, we can remove initial 45-degree CORDIC iteration and start from atan(1/2) pseudorotation, reducing expansion factor thereby. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macros. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Update. * src/tools/cordic.py: Bring up to date with trigonometric core. * docs/CHANGES: Old typo.
50e634ab 2013-01-02 20:31:56 * src/pshinter/pshalgo.h: Remove unused code.
7d6dc907 2012-12-27 01:08:24 * src/truetype/ttgload.c (tt_loader_init): Add more tracing.
2ef0a198 2012-12-23 21:14:37 [type1] Fix handling of /FontBBox in MM fonts. Problem reported by Del Merritt <del@alum.mit.edu> If we have /FontBBox { { 11 12 13 14 15 16 17 18 } { 21 22 23 24 25 26 27 28 } { 31 32 33 34 35 36 37 38 } { 41 42 43 44 45 46 47 48 } } in the /Blend dictionary, then the first BBox is { 11 21 31 41 }, the second { 12 22 32 42 }, etc. * include/freetype/internal/psaux.h (T1_FieldType): Add `T1_FIELD_TYPE_MM_BBOX' (for temporary use). * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_MM_BBOX>: Implement it.
f44f3f0e 2012-12-23 18:30:34 Formatting, minor internal documentation improvement.
cbf3fb39 2012-12-21 14:20:25 * src/tools/cordic.py: Bring up to date with trigonometric core.
3ffb822e 2012-12-21 16:45:27 Check parameters of `FT_Outline_New'. Problem reported by Robin Watts <robin.watts@artifex.com>. * src/base/ftoutln.c (FT_Outline_New_Internal): Ensure that `numContours' and `numPoints' fit into FT_Outline's `n_points' and `n_contours', respectively.
d7383b7b 2012-12-20 01:03:22 [base] Improve trigonometric core. FreeType used to rely on a 24-step iteration CORDIC algorithm to calculate trigonometric functions and rotate vectors. It turns out that once the vector is in the right half-plane, the initial rotation by 63 degrees is not necessary. The algorithm is perfectly capable to converge to any angle starting from the second 45 degree rotation. This patch removes the first rotation and makes it a 23-step CORDIC algorithm. * src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro values. (ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial rotation.
768590a9 2012-12-20 06:08:23 * src/base/ftobjs.c (ft_property_do): Fix compiler warning.
df018924 2012-12-20 06:07:33 Formatting.
32fc416f 2012-12-19 23:05:32 * src/base/ftrfork.c (FT_Raccess_Guess): Switch to FT_Int counters.
06174dbb 2012-12-19 22:46:27 [base] Clean up trigonometric core. * src/base/fttrrigon.c (ft_trig_pseudo_polarize): Align algorithm with `ft_trig_pseudo_rotate'.
1749ae20 2012-12-18 07:23:09 [truetype] Minor performance enhancement.
94b79e74 2012-12-17 19:17:30 [truetype] Remove unusued code and variables.
a9f6f85e 2012-12-17 09:08:09 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. (parse_blend_axis_types): Use cast. * src/bdf/bdflib.c (_bdf_readstream): Use cast.

309b8b31 2012-12-16 19:08:36 [sfnt] Fix Savannah bug #37936. * src/sfnt/ttload.c (tt_face_load_gasp): Avoid memory leak.
8ac5c5c8 2012-12-15 23:33:55 [base] Fix 11-year old bug. Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has always been slightly less than the correct value, which has been given in the comment as a hexadecimal. As a result, vector lengths were underestimated and rotated vectors were shortened.
7f2e4f4f 2012-12-15 09:39:41 [bdf] Fix Savannah bug #37907. * src/bdf/bdflib.c (_bdf_parse_glyphs) <ENCODING>: Normalize negative second parameter of `ENCODING' field also.
07bdb6e2 2012-12-15 02:02:23 [bdf] Fix Savannah bug #37906. * src/bdf/bdflib.c (_bdf_parse_glyphs): Use correct array size for checking `glyph_enc'.
9b6b5754 2012-12-15 01:34:41 [bdf] Fix Savannah bug #37905. * src/bdf/bdflib.c (_bdf_parse_start): Reset `props_size' to zero in case of allocation error; this value gets used in a loop in `bdf_free_font'.
65d65721 2012-12-10 06:59:29 [truetype] Scale F_dot_P down. The dot product between freeVector and projVector or cosine of the angle between these FT_F2Dot14 unit vectors used to be scaled up by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P. This patch scales the value down by 2^14 instead, which simplifies its use throughout the bytecode interpreter. This does not lead to the loss of precision because the lower bits are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8) for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666. These vectors are stored as (0x4000,0) and (0x2666,0x3333) after rounding and F_dot_P is assigned 0x26660000. The lower bits were already lost while rounding the unit vector components. Besides code simplification, this change can lead to better performance when FT_MulDiv with the scaled-down F_dot_P is less likely to use the costly 64-bit path. We are not changing the type of F_dot_P to FT_F2Dot14 at this point. * src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14 bits and modify its use accordingly. (Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify the use of F_dot_P field. * src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary assignment of F_dot_P to its theoretical maximum in case we decide to scale back its type later.

06d6916c 2012-12-09 00:07:51 [type1] Another fix for 2012-09-17 commit. * src/type1/t1parse.c (T1_Get_Private_Dict) <found>: Correctly set `limit' value.
cece4d3b 2012-12-06 20:23:38 [truetype] Tweak the previous commit. * src/truetype/ttinterp.c (Current_Ratio): Put unit vector components as the second TT_MulFix14 arguments. This is required on 16-bit systems.
5ad05f97 2012-12-06 00:27:20 [truetype] Microoptimizations in bytecode interpreter. * src/truetype/ttinterp.c (TT_DivFix14): New macro. (Normalize): Use it here. (Current_Ratio): Use TT_MulFix14 instead of FT_MulDiv. (Ins_SHPIX): Cancel out two TT_MulFix14 calls.
b50088bd 2012-12-05 23:05:47 [truetype] Cosmetic improvement in bytecode interpreter. * src/truetype/ttinterp.c: Use explicit calls to FT_MulDiv, FT_MulFix, and FT_DivFix instead of macros.
54d43a39 2012-12-05 11:14:41 [pshinter] Clamp BlueScale value. This is Savannah bug #37856. * src/pshinter/pshglob.c (psh_calc_max_height): New function. (psh_globals_new): Use it to limit BlueScale value to `1 / max_of_blue_zone_heights'.

553bb3c3 2012-10-24 14:22:14 [autofit] Add standard character to `AF_ScriptClassRec' structure. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `standard_char' member. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Use it. (af_latin_metrics_init, af_latin_script_class): Updated. * src/autofit/aflatin.c (af_latin2_metrics_init_widths): Use it. (af_latin2_metrics_init, af_latin2_script_class): Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Use it. (af_cjk_metrics_init, af_cjk_script_class): Updated. * src/autofit/afindic.c(af_indic_metrics_init, af_indic_script_class): Updated. * src/autofit/afcjk.h, src/autofit/aflatin.h: Updated. * src/autofit/afdummy.c: Updated.
118c6025 2012-10-24 12:26:20 [autofit] Only use Unicode CMap. * src/autofit/aflatin.c (af_latin_metrics_init): Implement it, to be in sync with `af_face_globals_compute_script_coverage)'.
8e82a961 2012-10-21 11:02:50 [psaux] Improve parsing of invalid numbers. * src/psaux/psconv.c (PS_Conv_Strtol): Always parse complete number, even in case of overflow. (PS_Conv_ToInt): Only increase cursor if parsing was successful. (PS_Conv_ToFixed): Ditto. Trace underflow and data error.
fdcbaf19 2012-10-21 10:40:12 [smooth] Improve tracing. * src/smooth/ftgrays.c (gray_sweep): Trace last sweep line of current band also.
24e897db 2012-10-20 22:23:01 [truetype] Cheaper way to threshold angles between vectors. * src/truetype/ttinterp.c (Ins_ISECT): Thresholding tangent is a lot cheaper than thresholding sine.
ad4eecca 2012-10-20 21:27:17 [cff] Improve parsing of invalid real numbers. * src/cff/cffparse.c (cff_parse_real): Always parse complete number, even in case of overflow or underflow. Also trace one more underflow.
