    - #### angle

          protected float angle

  - ### Constructor Detail

    - #### Rotate

          public Rotate()

  - ### Method Detail

    - #### setAngle

          public void setAngle(java.lang.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.
