Fair. But for
NumericComposite, I’d expect that e.g. if any of the elements is greater than any of the given elements, then it’s greater. One could also consider the vector length. In this case, ARGB(0, 0, 0, 255) or ARGB(0, 255, 0, 0) have the same length. I understand these are opinionated choices and non-obvious and therefore likely best avoided.
A related question then: is there a sensible way to collapse a
NumericComposite? E.g. if you express a 3D volume as a 2D of vectors, how can one easily apply the max to each composite pixel to do a max projection?
