public class ImageInputStreamWrapper
extends InputStream

This class is designed to wrap a ImageInputStream into a InputStream. The reason is that ImageInputStream implements DataInput but doesn't extend InputStream. However, the JJ2000 JPEG 2000 packages accepts a InputStream when reads a JPEG 2000 image file.
