Michael Niedermayer	a830915b78	swscale: Use full resolution chroma for yuv2rgb when the input has full chroma See Ticket3028 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Vittorio Giovara	6b3ff6f91a	swscale: provide a default scaler if none is set Lanczos for general case, sinc for upscaling, Gaussian for downscaling. According to current literature these scalers should be the best quality-wise algorithms for each case.

Michael Niedermayer	aec91de549	swscale/utils: Allow sws_setColorspaceDetails() to use the tables from sws_getColorspaceDetails() Previously this would have lead to a memcpy(a,a) which violates the requirement of non overlapping src and dst.

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.
