Method Details

executeDrawOperation

public 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.

executeTransformOperation

public PlanarImage executeTransformOperation(PlanarImage image)
Performs the image rotation when being handled as a TransformOperation.
Overrides:
executeTransformOperation in interface TransformOperation
Parameters:
image - The image to perform the transformation on.
Returns:
the transformed image.

performRotate

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

setAngle

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