- Present participle of dither.
dithering - Computer Definition
Simulating more colors and shades in a palette. In a monochrome system that displays and prints only black and white, shades of grays can be simulated by creating varying patterns of black dots. This is how continuous-tone images are created in a monochrome printer (see halftone). In color systems, additional colors can be simulated by varying patterns of dots of existing colors. Dithering cannot produce the identical results as having the necessary pixel depth (levels of gray or colors), but it can make shaded drawings and photographs appear extremely realistic. See bit depth. Dithering is also widely used to smooth curved and diagonal edges (see anti-aliasing).
