The representation of a digital image as a bitmap, which comprises rows and columns (a matrix) of picture elements (pixels). Also called "bitmap graphics" and "raster graphics," the images generated by digital cameras, camcorders and scanners are bitmaps, as well as images created in paint programs. Popular bitmap file formats are JPEG, PNG, GIF and TIFF (see
graphics formats). Bitmapped graphics and "vector graphics" are the two fundamental architectures of digital images (for details, see
graphics). See
