Class TwirlFilter

  • All Implemented Interfaces:
    java.awt.image.BufferedImageOp, 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.
