Not quite sure what this word means in this context, but last time I thought about it I drew something like that: 8bit 16bit +------ 32768.0 (= 1<<15) | 255 +------ 32703.75 | | 254 | +------ | | 253 | +------ ... +------ 129.75 | | 1 97.0 | +------ 64.25 | 0 32.125 +------ 0 I am not certain that it is what is implemented or what we actually want. Maybe we should look into babl rounding. > On the upside, I have implemented said dithering and it works pretty > well (and fast.) :) That's good news :-) -- Martin Renold _______________________________________________ Mypaint-discuss mailing list [email protected] https://mail.gna.org/listinfo/mypaint-discuss
