All Implemented Interfaces:

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

public class TwirlFilter
extends TransformFilter

A Filter which distorts an image by twisting it from the centre out. The twisting is centred at the centre of the image and extends out to the smallest of the width and height. Pixels outside this radius are unaffected.

Constructor Detail

TwirlFilter

public TwirlFilter()

Construct a TwirlFilter with no distortion.

Method Detail

setAngle

public void setAngle(float angle)

Set the angle of twirl in radians. 0 means no distortion.

Parameters:

angle - the angle of twirl. This is the angle by which pixels at the nearest edge of the image will move.

getAngle

public float getAngle()

Get the angle of twist.

Returns:

the angle in radians.

setDimensions

public void setDimensions(int width,
                          int height)

Specified by:

setDimensions in interface java.awt.image.ImageConsumer

Overrides:

setDimensions in class WholeImageFilter

transformInverse

protected void transformInverse(int x,
                                int y,
                                float[] out)

Specified by:

transformInverse in class TransformFilter

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
