1. data, graphics Data representing a two-dimensional scene.
A digital image is composed of pixels arranged in a
rectangular array with a certain height and width. Each pixel
may consist of one or more bits of information, representing
the brightness of the image at that point and possibly
including colour information encoded as RGB triples.
Images are usually taken from the real world via a digitalcamera, frame grabber, or scanner; or they may be
generated by computer, e.g. by ray tracing software.
