An image formed (or appearing to be formed) by a rectangular grid of pixels. The computer assigns a value to each pixel, from one bit of information (black or white), to as much as 24 or 30 bits per pixel for full color images. Also used to refer to an image that has a too low resolution or linescreen for the output resolution (“That image looks bitmapped.”; line art scanned at 72dpi when it is to be printed at 2540dpi will be very coarsely bitmapped).
