Converting vectors to bitmaps

Most Flash projects take full advantage of Flash's vector rendering engine and timeline animation system. Rendering vector content, however, can be computationally expensive, particularly with complex vector shapes that contain a large number of control points, gradients, and alpha transparency.

Although even a modest desktop computer can easily render the vector graphics found in most Flash projects; mobile devices are optimized for bitmap graphics meaning compromises need to be made sometimes. Drawing bitmaps is typically less expensive than vectors.

Where performance is critical, consider converting complex vector artwork into bitmaps. If your project already contains existing vector content, then you can use Flash ...
