Field Detail

### 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.
