raster - n., the pattern of closely spaced dots scanned in horizontal lines on a cathode ray tube that makes up a picture.


Also, the scanning pattern to create such a pattern. Also, a pixel of a bitmap image, as opposed to a vectorized description of the image. The above definition came first, though, via German, from Latin rastrum, rake, from the resemblance of the parallel lines (especially in early CRTs) to a rake's path.
