A bitmap graphic, is a data file or structure representing a generally rectangular grid of pixels, or points of color, on a computermonitor, paper, or otherdisplaydevice. The color of each pixel is individually defined; images in the RGB color space, for instance, oftenconsist of colored pixels defined by three bytesone byte each for red, green and blue. Less colorful images require less information per pixel; an image with onlyblack and white pixels requires only a single bit for each pixel. Raster graphics are distinguished from vector graphics in that vector graphics represent an image through the use of geometric objects such as curves and polygons.
