public class JBaycamMosaic
extends JMosaic
implements ConditionalRefreshing

A baycam mosaic consists of images taken by the STELLA baycam. Each tile takes it images from KEY_BAYCAMHOST, matches them with KEY_BAYCAMNAMES and updates them regularily using the time base in KEY_BAYCAMUPDATE. The number of file names in KEY_BAYCAMNAMES defines the number of rows. The size of the individual tiles can be set with JMosaic.KEY_TILESIZE from the base class. Specifying a height of -1 there keeps the aspect ratio of the webcam images.
