Hi All,

I think not.  A pseudo pair needs the images transposed with no rotations
or reflections at all.  Turning round a pair in that way gives you a
slide which is pseudo *and* reversed.

Since I don't use slides I just tweaked a JPS file in Paint Shop, and it
was still cross-eyed as a mirror image.

P.S. I take it you already know, having turned your pseudo slide around.
