optimization

I am working on a basic isometric game, and am struggling to find the correct mirrors.

Mirror can be any form of transform.

I have managed to get SE out of SW, by scaling the sprite on X axis by -1. Same applies for NE angle.

Something is bugging me, that I should be able to also mirror N to S, but I cannot manage to pull this one off.

Am I just too sleepy and trying to do the impossible, or a basic -1 scale on Y axis is not enough?

What are the common used mirror table for optimizing 8 angle (N, NE, E, SE, S, SW, W, NW) isometric sprites?
