Computer graphics fall into two main categories--vector graphics and bitmap images. Vectors describe graphics according to their geometric characteristics. For example, a bicycle tire in a vector graphic is made up of a mathematical definition of a circle drawn with a certain radius filled with a specific color. Vector graphics are good for reproducing crisp outlines. They can be printed at any size without losing detail. Bitmap images are good for reproducing subtle gradations of color, as in photographs.The images use a grid (also known as a bitmap or raster) of small squares, known as pixels, to represent graphics. They can have jagged edges when printed at too large a size.

The image to the left is the bottom left corner of the Canyon Floor print at actual size. Each shape was individually drawn and you can see how crisp and clear the borders of each shape are.
