The representation of a digital image as a matrix of picture elements (pixels). All images acquired by digital cameras and camcorders, scanners and screen capture programs are bitmapped images. Also known as "raster graphics, images created in paint programs are also bitmapped images. There are many bitmapped formats, including JPEG, GIF, BMP and TIFF (see graphics formats). Bitmapped graphics and "vector graphics" are the two fundamental structures for digital images (see graphics for details).
