public class Image
A MatchingTask which relies on JAI (Java Advanced Imaging) to perform image manipulation operations on existing images. The operations are represented as ImageOperation DataType objects. The operations are arranged to conform to the Chaining Model of JAI. Check out the JAI Programming Guide.
