### 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.
