rorateview.swiftlet bitmap: CGContext = UIGraphicsGetCurrentContext()! //Move the origin to the middle of the image so we will rotate and scale around the center. let newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
CGFloat radians = atan2f(self.view.transform.b, self.view.transform.a);
CGFloat degrees = radians * (180 / M_PI);
