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 8x8 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 8x8 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.
