When you publish a Flash document, you're not limited to just the cre-
ation of the Flash movie, you can instruct Flash to create a GIF image of
the Flash movie, based on the currently selected frame. The GIF file for-
mat (Graphics Interchange Format) is used primarily for clipart, text,
and line art, or for images that contain areas of solid color. Once the
image is created, you can open and use it in any application that sup-
ports the GIF file format.

Chapter 20
When you publish a Flash document, you're not limited to just the cre-
ation of the Flash movie, you can instruct Flash to create a JPEG image
of the Flash movie, based on the currently selected frame. The JPEG
file format (Joint Photographic Experts Group), is used primarily to
reduce the size of photographic images. Once the image is created,
you can open and use it in any application that supports the JPEG file
format. You can select a quality option to compress the file size, which
reduces download time over the Internet. You can specify a quality
value between 1 and 100. A higher value preserves image quality, but
retains a higher file size.

or decrease the amount of
compression applied to the image.

information (quality) is removed
from the image.
Select the Progressive check box

image. The file, when displayed on
a Web page, loads in three passes.
Click OK to save the JPEG settings.
