It assumes the ndarray has format (samples, height, width, channels), if given in this format it works fine. See How to write your own v2 transforms for more details. Examples using ToImage: The ToImage transform is in Beta stage, and while we do not expect disruptive breaking changes, some APIs may slightly change according to user feedback.
