Amazingly complex illustrations are thus possible. Since each curve is based upon a mathematical formula, it is resolution independent. And, printing is always at the best quality. Bitmapped graphics are essentially a grid of dots. Each dot can be any color allowed by the system.
Bitmapped graphics have a fixed resolution.
But that does not mean that it will always be the same size. That s not a good thing. A further problem with bitmapped graphics is that as the image resolution increases, the file size increases dramatically. A 256 color, 100x100 image takes 10,000 bytes. A 256 color, 300x300 image takes 90,000 bytes.
