Vector vs. Bitmap

   

Macromedia Flash MX is a vector-based application. Computers display graphics in either vector or bitmap format. Once you understand the difference between the two, you can begin to build more efficient Flash documents.

Vector graphics are drawn mathematically. They are based on the points of an object. The color , shape, size , and position of the object can change without losing any quality of its appearance. Vector graphics are also resolution independent, meaning they can be displayed on monitors with different screen resolutions and not forfeit a bit of quality (see Figure 3.1).

Figure 3.1. A close-up reveals the difference between vector and bitmap graphics.

Bitmap graphics are images that use an amalgamation of pixels. When you modify a bitmap graphic, you change pixels as opposed to lines and curves. Bitmap graphics are resolution dependent because the pixels are fixed to a grid of a specific size (see Figure 3.1).
