question: public Point2D inverseTransform ( Point2D src , Point2D dst ) { try { src . setLocation ( src . getX ( ) + rotXOffset , src . getY ( ) + rotYOffset ) ; dst = rotTransform . inverseTransform ( src , dst ) ; } catch ( NoninvertibleTransformException e ) { logger . log ( Level . FINE , e . getMessage ( ) , e ) ; } return dst ; }
target:  Returns dst, the unrotated pixel location of the map.
