Method Details
-
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 classTransformOperation
- 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 interfaceDrawOperation
- Returns:
- the image.
