(1) (n.) The array of values in the frame buffer for a given picture, particularly in the case of multibit displays. (2) (n.) A 3-D array of bits. A pixmap is usually a 2-D array of pixels but can also be a stack of bitmaps.
A non-displayable region of the frame buffer into which rendering may occur. In the X Window System, a pixmap is defined to be very similar to a window. The X notion of a pixmap has to be extended in order to use pixmaps for IVL rendering. See GLX pixmap.
(1) A data type to which icons, originally created as bitmaps, are converted. After this conversion, the appropriate subroutines can generate pixmaps through references to a defaults file, by name, and through an argument list, by pixmap. (2) An abbreviation for pixel map. See pixel map.
