Class ReinterpretDescriptor

java.lang.Object

javax.media.jai.OperationDescriptorImpl

com.bc.ceres.jai.operator.ReinterpretDescriptor

All Implemented Interfaces:

Serializable, javax.media.jai.OperationDescriptor, javax.media.jai.RegistryElementDescriptor

public class ReinterpretDescriptor
extends javax.media.jai.OperationDescriptorImpl

An OperationDescriptor describing the "Reinterpret" operation.

The Reinterpret operation creates a single-banded, tiled rendered image, where the source samples are rescaled or reformatted.

                                                RenderingHints hints)

Reinterprets an image.

Creates a ParameterBlockJAI from all supplied arguments (except hints) and invokes JAI.create(String,java.awt.image.renderable.ParameterBlock,java.awt.RenderingHints).

Parameters:

source - The RenderedImage source.

factor - The scaling factor.

offset - The scaling offset.

scalingType - The manner of scaling.

interpretationType - The interpretation type.

hints - The RenderingHints to use. May be null.

Returns:

The RenderedOp destination.

Throws:

IllegalArgumentException - if source is null.
