Pattern Maps and Labels
Most, if not all, computer-based windowing systems have a means of displaying a fixed pattern on a window in such a way as to involve minimal processing. This is the generic pattern format of the windowing system. For the X Window System, this format is a Pixmap. There are two sub-categories of Pixmap: the single bit (or black and white) bitmap and the more general PixMap which is capable of representing colour. A complication is X Window System refers to the analogue of a window as a Pixmap. But all what can be done on, or with, a window is not true for a map-type Pixmap.
