Class DFTConvolveDescriptor

  • All Implemented Interfaces:
    Serializable, javax.media.jai.OperationDescriptor, javax.media.jai.RegistryElementDescriptor
    public class DFTConvolveDescriptor
extends javax.media.jai.OperationDescriptorImpl
    An OperationDescriptor describing the "DFTConvolve" operation.

    This operation behaves as the JAI standard "Convolve" operation but uses a Fast Fourier Transformation for the convolution.

        public static javax.media.jai.RenderedOp create​(RenderedImage source0,
                                                javax.media.jai.KernelJAI kernel,

                                                RenderingHints hints)
        Performs kernel-based convolution on 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:
        source0 - RenderedImage source 0.
        kernel - The convolution kernel.
        kernelFT - The Fourier-transformed convolution kernel image, may be null.
        hints - The RenderingHints to use. May be null.
        Returns:
        The RenderedOp destination.
        Throws:
        IllegalArgumentException - if source0 is null or if if kernel is null.
