Using Bitmaps (Also Known as Raster Graphics)

In this section we'll see how bitmapped (raster) graphics can be used in Flash. Raster graphics have inherently unique characteristics that can't be created inside Flash. The only warning against this option is to make sure you really need raster graphics. Here is a summary of uses that require raster graphics:

• A photograph. The only time to consider a vector alternative to a photograph is when the picture is of a very geometric object. Otherwise, photographs should be raster.

• A series of still images extracted from frames of a video.

• An image with special effects that can't be achieved with a vector tool, such as clouds, fire, water, and other natural effects. (Of course, this is an invitation for a talented artist to re-create such an effect with a vector tool.)
