Package com.jhlabs.image
Class TwirlFilter
java.lang.Object
com.jhlabs.image.AbstractBufferedImageOp
com.jhlabs.image.TransformFilter
com.jhlabs.image.TwirlFilter
- All Implemented Interfaces:
BufferedImageOp
,Cloneable
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.

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.
