public class TimeBoundPainter

extends Object

This class paints an image from a queue of images. Each pass has a maximum number of items in the queue. If the maximum number of items has not been posted to the queue and drawn to the outer image by the time specified, then the image rendering is canceled.

When the painting is completed, an event is fired telling everyone that the next frame is ready to be painted.
