Just want to clarify. Am I right that your solution isn't applicable to PiecewiseAffineTransform at all? Do you think it may be possible to find a workaround?
Sorry, I should have been clearer. With "defined" I meant implemented.
Upon closer inspection, it turns out that the PiecewiseAffineTransform *does* have an inverse implemented. It was the "+" operator causing the problem. Still, I have found cases now where I get invalid answers for valid- seeming sets of coordinates. I'm investigating further, but I think I have a solution to your problem. Stéfan
