Brain Freeze – please put me out of my misery!

I feel like part of my brain is missing today. The simplest of things…..

Please let me know why this 8×8 grid doesn’t rotate properly (should be by 90 degrees)

you might have better luck if you keep your matrix dimension aspect ratio the same as the input movie. eg 8 6, or 12 9, etc.

you might also want to do your rotation first, and then downsample.

Thanks. Actually I only want to rotate an 8×8 grid by 90 degrees.
Jit.rota must be doing some complicated (and in this case inaccurate) Maths which I don’t need.
In the cold light of morning I think jit.dimmap is the way to go.
