* [base] Improve trigonometric core.Alexei Podtelezhnikov2012-12-202-41/+27
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | * 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.

* [sfnt] Fix Savannah bug #37936.Werner Lemberg2012-12-162-4/+10

* [base] Fix 11-year old bug.Alexei Podtelezhnikov2012-12-152-1/+12
| | | | | | | 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.

* [truetype] Scale F_dot_P down.Alexei Podtelezhnikov2012-12-103-26/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
