public class ImageIOTask
extends MatchingTask
A MatchingTask which relies on Java ImageIO to read existing image files and write the results of AWT image manipulation operations. The operations are represented as ImageOperation DataType objects. The task replaces a JAI-based Image task which no longer works with Java 9+.
