Øyvind Kolås	3e6016622e	swscale: add two spatially stable dithering methods Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results	11 years ago
Michael Niedermayer	ccf96f8c64	swscale/options: switch default to bicubic Suggested-by: Ronald S. Bultje Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
wm4	01e3340fb6	swscale: make bilinear scaling the default Before this commit, sws_init_context() failed with an error if no scaler was explicitly set. Defaulting to something reasonable is better behavior. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
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.

Stefano Sabatini	605f1d9865	lsws: define version in SWScaler class The version number is useful to check the libavutil version against which the library was compiled at run-time, which in turn may be useful to deal with binary compatibility issues.	12 years ago
