  - ### setAngle

    public void setAngle(String ang)
    Sets the angle of rotation in degrees.
    Parameters:
      `ang` - The angle at which to rotate the image

  - ### performRotate

    public javax.media.jai.PlanarImage performRotate(javax.media.jai.PlanarImage image)
    Rotate an image.
    Parameters:
      `image` - the image to rotate.
    Returns:
      the rotated image.

  - ### executeTransformOperation

    public javax.media.jai.PlanarImage executeTransformOperation(javax.media.jai.PlanarImage image)
    Performs the image rotation when being handled as a TransformOperation.
    Specified by:
      `executeTransformOperation` in class `TransformOperation`
    Parameters:
      `image` - The image to perform the transformation on.
    Returns:
      the transformed image.

  - ### executeDrawOperation

    public javax.media.jai.PlanarImage executeDrawOperation()
    Performs the image rotation when being handled as a DrawOperation. It absolutely requires that there be a DrawOperation nested beneath it, but only the FIRST DrawOperation will be handled since it can only return ONE image.
    Specified by:
      `executeDrawOperation` in interface `DrawOperation`
    Returns:
      the image.
