Hi Martin, re: this commit: http://gitorious.org/mypaint/mypaint/commit/f40b2b74160b8fffca424b6ee73c276195e50666
Is the reason you didn't try ordered dithering[1] the same reason error-diffusion proved suboptimal*, or some other reason? (*ie, dithering changes when layer bounds change.) If same tile alignment is guaranteed over time (ie. boundaries of tiles don't shift between saves, regardless of layer expansion.. they only are added or removed at the sides), and adding 256 bytes of static data is okay, then ordered dither should work quite well; it should provide good quality, be much faster than random dither, and not change between saves. I'd be happy to implement it. Thanks for taking the time to read this :) David Gowers [1] http://en.wikipedia.org/wiki/Ordered_dithering _______________________________________________ Mypaint-discuss mailing list [email protected] https://mail.gna.org/listinfo/mypaint-discuss
