(1) To smooth out any jagged edges of a curve (for example, in a drawing or on a character) by placing shaded pixels between the pixels that make up the curve. Some graphics programs will do this automatically and some high-resolution laser printers will do this to improve the quality of the print. (2) To create a new colour by displaying a pattern of coloured pixels that appears, to the eye, as a new colour. The eye blends the tiny pixels together and is fooled into thinking that this is a new colour. For example, a pattern of black and white pixels equally spaced would appear as grey; increase the number of black pixels and the grey darkens.
