Abstract:


    What is Raster Graphics? Raster graphics is an area of computer graphics based upon a particular technology for displaying images: the simple CRT raster scan used by the millions of TV sets around the world. In a raster scan, the CRT’s electron beam follows a fixed pattern, which is repeated about 30 times a second. An image is created by varying the intensity of the electron beam. In simple systems the intensity variation is between the on and off states, while more complex systems allow multiple levels of intensity and/or color.
