UIImageOrientation documentation is incorrect

Question

Looking through Apple's documentation for UIImageOrientation I notice that the images that go with the descriptions are incorrect.

https://developer.apple.com/reference/uikit/uiimageorientation

This has been painful for me, so I'm going to leave this here, with the correct images in the answer in case others find the same.

If people think this shouldn't be here, please comment / vote down and I'll remove.

Answer 1

Here's how I got the correct images:

extension UIImage {

    var normalised: UIImage {

        if imageOrientation == .up {
            return self
        }

        var normalisedImage: UIImage

        let format = UIGraphicsImageRendererFormat.default()
        format.scale = scale
        format.opaque = true
        format.prefersExtendedRange = false
        normalisedImage = UIGraphicsImageRenderer(size: size, format: format).image { _ in
            draw(in: CGRect(origin: .zero, size: size))
        }

        return normalisedImage
    }

    func translated(to orientation: UIImageOrientation) -> UIImage {
        guard let cgImage = cgImage else {

            return self
        }

        return UIImage(cgImage: cgImage, scale: 1, orientation: orientation).normalised
    }
}

Then using this image as the "base"
