For example, consider how computer graphics co… Computer Graphics: Theory into Practice by Jeffrey J. McConnell. At the end of each scan line, the electron beam returns to the left side of the screen to begin displaying the next scan line. One bit per pixel suffices for black-and-white images, while four bits per pixel specify a 16-step gray-scale image. Random-scan displays are designed to draw all the component lines of a picture 30 to 60 times each second. In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images.
