Graphics dithering
WebDithering is a way to somehow spread out a color throughout multiple pixels to compensate for low bit depth of the individual pixels. Pixels have sharper changes, but they are made to average to as close to the original picture as possible, if you consider local averages (so that it looks as close to the original as it could look to the human eye). WebDec 28, 2012 · Dithering also has applications in web design, where it is a useful technique for reducing images with high color counts to lower color counts, reducing file size (and …
