Michael Niedermayer	1e0e193240	sws: add dither enum This allows specifying more dither algorithms without using up flags and without ambiguities. Also initialize the new field based on the flags and use it. Note, improving the logic of the checks is left to subsequent commits, this here only switches from flags to enum.

Ronald S. Bultje	4860625236	swscale: fix off-by-one in second coefficient in bilinear filters. If coefficient A is 12-bits xixed-point number "X", then the other coefficient is (1 << 12) - X, not (1 << 12) - X - 1.	13 years ago

Ronald S. Bultje	25c42234a9	swscale: make monowhite/black RGB-independent. Disadvantage is that it no longer allows modifying brightness through adjustment of the RGB lookup table. Advantage is that now monowhite/black no longer need to be identified as a RGB format.	13 years ago

Ronald S. Bultje	c0b87359b2	swscale: handle gray16 as a "planar" YUV format (Y-only, of course). This allows removing any gray16-specific code, which is essentially identical to the per-plane code in yuv2plane*().	13 years ago
