2 definitions found From WordNet r 1.6 [wn]: dithering n : the process of representing intermediate colors by patterns of tiny colored dots that simulate the desired color From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: dithering A technique used in {computer graphics} to create additional colors and shades from an existing {palette} by interspersing {pixel}s of different colours. On a {monochrome} display, areas of grey are created by varying the proportion of black and white pixels. In color displays, colors and textures are created by varying the proportions of existing colors. The different colours can either be distributed randomly or regularly. The higher the {resolution} of the display, the smoother the dithered colour will appear to the eye. Dithering is used to create patterns for use as backgrounds, fills and shading, as well as for creating {halftones} for printing. It is also used in {anti-aliasing} in order to make jagged lines appear smoother on screen. (1994-11-02)
