bitmapped graphics

The common representation of a digital image as a matrix (rows and columns) of picture elements (see bitmap). All CRT, LCD, OLED and plasma screens are bitmapped-graphics displays. Images acquired by digital cameras, digital camcorders and scanners are bitmaps. Also known as "raster graphics," images created in paint programs are bitmapped. There are many bitmapped formats, including JPEG, GIF, BMP and TIFF (see graphics formats). Bitmapped graphics and "vector graphics" are the two fundamental architectures of digital images (see graphics for details).
