org.apache.batik.ext.awt.image.renderable.ConvolveMatrixRable8Bit

All Implemented Interfaces:

RenderableImage, ConvolveMatrixRable, Filter, FilterColorInterpolation

public class ConvolveMatrixRable8Bit
extends AbstractColorInterpolationRable
implements ConvolveMatrixRable

Convolves an image with a convolution matrix. Known limitations: Does not support bias other than zero - pending 16bit pathway Does not support edgeMode="wrap" - pending Tile code.
