Bit-Mapped Graphics, in computer science, computer graphics that are stored and held as collections of bits in memory locations corresponding to pixels on the screen. Bit-mapped graphics are typical of paint programs, which treat images as collections of dots rather than as shapes. Within a computer's memory, a bit-mapped graphic is represented as an array (group) of bits that describe the characteristics of the individual pixels making up the image. Bit-mapped graphics displayed in color require several to many bits per pixel, each describing some aspect of the color of a single spot on the screen.
