Short for picture element; the smallest dot you can draw on the screen. Also a location in video memory that corresponds to a point on the graphics screen when the viewing window includes that location. In the Macintosh monochrome display, each pixel can be either black or white, so it can be represented by a bit; thus, the display is said to be a bitmap. For color or gray-scale video, several bits in RAM may represent the image; in the Super Hi-Res display on the Apple IIGS, each pixel is represented by either two or four bits. Thus, the display is not a bitmap, but rather a pixel map.
