Optimizations

Convert line styles to solid - Converts lines that use styles to solid lines. Otherwise, since Flash does not support line styles, the elements of those lines are converted to individual objects, which increases the file size.

Export gradients - Includes gradients in the exported file. Note that Flash does not support all Designer gradient options.

Export text as curves - Saves text as geometry rather than font-based text.

Animation

Rate - Sets the frame rate for the animation in frames per second (fps). The default is 12 fps.

Autoplay - Sets the animation so that it plays as soon as it is loaded (rather than waiting for user interaction).

Images

Compression - Sets the type of compression for images: none, JPEG (best for photographs), or Zlib (best for other types of images).

JPEG Quality - For JPEG images, sets the quality. Lower quality decreases the file size but has less picture information; higher quality has more picture information but increases the file size.

Bounding box

Sets the size of the animation. It can either be the size of the Designer page or the size of the bounding box of the objects (the used area). If you size it to the objects, you can select a relative margin size.

Layers

Determines whether layers are converted to frames for animation or merged to create a static illustration.
