public class RotateDescriptor

extends OperationDescriptorImpl

An OperationDescriptor describing the "Rotate" operation.

The "Rotate" operation rotates an image about a given point by a given angle, specified in radians. The origin defaults to (0, 0).

It may be noted that the minX, minY, width and height hints as specified through the JAI.KEY_IMAGE_LAYOUT hint in the RenderingHints object are not honored, as this operator calculates the destination image bounds itself. The other ImageLayout hints, like tileWidth and tileHeight, however are honored.

"Rotate" defines a PropertyGenerator that performs an identical transformation on the "ROI" property of the source image, which can be retrieved by calling the getProperty method with "ROI" as the property name.
