The purpose of this page is to help you to understand representations of images other than bitmaps. Vector graphics, for example, contain descriptions of the shapes used to make the image, rather than a grid of pixels that represent the image. This generally makes the file smaller, but as it only stores information about the shapes drawn, the size of the file will increase as the image gets more complex.
