Description: declaration: package: org.apache.tools.ant.taskdefs.optional.image, class: Image

Package org.apache.tools.ant.taskdefs.optional.image

# Class Image

java.lang.Object
org.apache.tools.ant.ProjectComponent
org.apache.tools.ant.Task
org.apache.tools.ant.taskdefs.MatchingTask
org.apache.tools.ant.taskdefs.optional.image.Image

All Implemented Interfaces:
  `java.lang.Cloneable`, `SelectorContainer`

    @Deprecated
    public class Image
    extends MatchingTask

Deprecated.
JAI is not developed any more. Internal APIs that JAI depends on were scheduled for removal in Java 7 and finally removed in Java 9.
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.
