Class MosaicMaker

java.lang.Object
  com.hdcookbook.grin.mosaic.MosaicMaker

public class MosaicMaker
extends java.lang.Object

This class has the main logic for making a set of image mosaics for one or more GRIN show files. An image mosaic is a bunch of little images that are stuck together into one big image, plus data about where each little image was put in the mosaic. By packaging images as a mosaic, the startup time of an xlet can be dramatically improved, since many image decoders have a substantial fixed latency that doesn't vary much with image size.
