One thing that makes Flash such an incredible Web development tool is its use of vector graphics as the default graphics mode. Vector graphics are objects defined by mathematical equations, or vectors, that include information about the object's size, shape, color, outline, and position. This efficient mode of handling graphics keeps files relatively small—even when you're dealing with complex drawings. What's more, because vector graphics are resolution independent, a vector graphic the size of a pinhead will retain the same file size—with no degradation in quality—even when enlarged to fit your entire screen (Figure 1.1).
