- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class IDCTDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor describing the "IDCT" operation.
The "IDCT" operation computes the inverse even discrete cosine transform
(DCT) of an image. Each band of the destination image is derived by
performing a two-dimensional inverse DCT on the corresponding band of the
source image.

create
public static RenderedOp create(RenderedImage source0,
RenderingHints hints)
- Computes the inverse discrete cosine transform of an image.
Creates a ParameterBlockJAI from all
supplied arguments except hints and invokes
JAI.create(String,ParameterBlock,RenderingHints).
- Parameters:
source0 - RenderedImage source 0.hints - The RenderingHints to use.
May be null.- Returns:
- The
RenderedOp destination. - Throws:
IllegalArgumentException - if source0 is null.- See Also:
