Class TransformFilter

java.lang.Object

com.jhlabs.image.AbstractBufferedImageOp

com.jhlabs.image.TransformFilter

All Implemented Interfaces:

java.awt.image.BufferedImageOp, java.lang.Cloneable

Direct Known Subclasses:

BlockFilter, CircleFilter, CurlFilter, DiffuseFilter, DisplaceFilter, FieldWarpFilter, KaleidoscopeFilter, MapFilter, MarbleFilter, OffsetFilter, PerspectiveFilter, PinchFilter, PolarFilter, RippleFilter, RotateFilter, ShearFilter, SphereFilter, SwimFilter, TwirlFilter, WaterFilter

public abstract class TransformFilter
extends AbstractBufferedImageOp

An abstract superclass for filters which distort images in some way. The subclass only needs to override two methods to provide the mapping between source and destination pixels.
