        func flipImageOnHorizontalAxis(theImage: UIImage,imageView:UIImageView) -> UIImage {
            var orient: UIImageOrientation!
            let imgOrientation = theImage.imageOrientation
            UIView.transition(with: imageView, duration: 0.4, options: .transitionCrossDissolve, animations: {() -> Void in

            let mirroredImage = UIImage(cgImage: theImage.cgImage!, scale: 1.0, orientation: orient)
            return mirroredImage
        }
        func flipImageOnVerticalAxis(theImage: UIImage,imageView:UIImageView) -> UIImage {
            var orient: UIImageOrientation!
            let imgOrientation = theImage.imageOrientation
            UIView.transition(with: imageView, duration: 0.4, options: .transitionCrossDissolve, animations: {() -> Void in
                switch imgOrientation {
                case .left:
                    orient = .leftMirrored
                case .right:
                    orient = .rightMirrored
                case .up:
                    orient = .downMirrored
                case .down:
                    orient = .upMirrored
                case .upMirrored:

                    orient = .up
                case .leftMirrored:
                    orient = .left
                case .rightMirrored:
                    orient = .right
                }
            }, completion: { _ in })
            let mirroredImage = UIImage(cgImage: theImage.cgImage!, scale: 1.0, orientation: orient)
            //let mirroredImage = UIImage(CGImage: theImage.CGImage!, scale: 1.0, orientation: orient)
            return mirroredImage
        }
//MARK: To call the above function this can be done like this:
flipImageOnHorizontalAxis(theImage: imageView.image!, imageView: imageView)
or
flipImageOnVerticalAxis(theImage: imageView.image!, imageView: imageView)
