public static void writeGif(java.awt.Image[] still_images,
                            java.lang.String annotation,
                            boolean looped,
                            double frames_per_second,
                            java.io.OutputStream os)
                     throws java.io.IOException

Parameters:

still_images - images to be written

annotation - text to be embedded into the gif animation

looped - true means looped on playback

frames_per_second - an int

os - OutputStream to send animation to.

Throws:

java.io.IOException - If you run out of disk space
