Dictionary definition(s) for: bitmap

• n., A digital representation composed of dots arranged in rows and columns, each represented by a single bit of data that determines the value of a pixel in a monochrome image on a computer screen. In a gray scale or color image, each dot is composed of a set of bits that determine the individual values of a group of pixels that in combination create the visual impression of a specific shade or hue. Also spelled “bit map.”
