Raster graphics refers to computer graphics in which an image is composed of an array of pixels arranged in a grid of rows and columns.. 1995-03-22. The counterpart to this display method is vector graphics.. 2001-02-06.
==Description==
The term originates from vintage cathode-ray tube (CRT) video displays that were covered by a sweeping electron beam that would illuminate pixels in a series of horizontal lines from top to bottom. The beam then returns to the top during the vertical flyback interval to draw the next image.. 1995-03-22. The speed of this process is referred to as the frame rate.. 2000-02-02.
Raster graphics were once synonymous with monochromatic bitmap graphics when the simple binary (on/off) state of each bit corresponded with the illumination of a pixel. However, the color depth of raster graphics have since expanded to be able to display RGB color values with increasing precision.. 1996-09-21.
