about image Formats Flash supports multiple image formats for import. Flash can handle JPEG, GIF, PNG, and PSD (Photoshop) files. Use JPEG files for images that include gradients and subtle variations, such as those that occur in photographs. GIF files are used for images with large solid blocks of color or black and white line drawings. Use PNG files for images that include transparency. Use PSD files if you want to retain all the layer, transparency, and blending information from a Photoshop file.

Converting a Bitmap Image to a Vector Graphic Sometimes you ll want to convert a bitmap image to a vector graphic. Flash handles bitmap images as a series of colored dots or pixels vector graphics are handled as a series of lines and curves. This vector information is rendered on the fly so that the resolution of vector graphics is not fixed like a bitmap image. That means you can zoom in on a vector graphic and your computer will always display it sharply and smoothly. Converting a bitmap image to a vector often has the effect of making it look posterized because subtle gradations are converted to editable discrete blocks of color which can be an interesting effect. To convert a bitmap to a vector import the bitmap image into Flash. Select the bitmap and choose Modify Bitmap Trace Bitmap. The options determine how faithful of a trace the vector image will be to the original bitmap. In the following figure the left image is an original bitmap and the right image is a vector graphic. Exercise caution when using the Trace Bitmap command because a complicated vector graphic is often more memory and computer-processor intensive than the original bitmap image.
