graphics (Or "bitplane") The memory in a graphic display
device which holds a complete one-bit-per-
pixel image.
Several bit planes may be used in conjunction to give more
bits per pixel or to overlay several images or mask one with
another.
"Bit plane" may be used as a synonym for "
bitmap", though
the latter suggests the data itself rather than the memory and
also suggests a graphics file format.
