A binary representation in which a bit or set of bits corresponds to some part of an object such as an image or font. For example, in monochrome systems, one bit represents one pixel on screen. For gray scale or color, several bits in the bitmap represent one pixel. The term may refer to the image itself or to the memory area that holds the bits that represent the image. See pixel and rasterize.Graphics and TablesA bitmap is usually associated with graphics, in which the bits are a direct representation of the pixels in the image.
