All Implemented Interfaces:

java.awt.image.ImageConsumer, java.io.Serializable, java.lang.Cloneable

public class WarpFilter
extends WholeImageFilter

A filter for warping images using the gridwarp algorithm. You need to supply two warp grids, one for the source image and one for the destination image. The image will be warped so that a point in the source grid moves to its counterpart in the destination grid.
