public class VideoPanel
extends InteractivePanel
implements java.beans.PropertyChangeListener

This is an interactive drawing panel with a video player. It can draw videos and other Trackable objects in either imagespace or worldspace. When drawing in imagespace, the image reference frame (ie the image itself) is fixed. When drawing in worldspace, the world reference frame is fixed. The image reference frame defines positions in pixel units relative to the upper left corner of a video image--ie, the UL corner of a 320 x 240 video is at (0.0, 0.0) and the LR corner is at (320.0, 240.0). When drawing in imagespace, non-Trackable objects are not drawn.
