Definitely too hard for a beginner :-) Probably I should just increase image
canvas size to have empty area cropped and the picture to remain full. Thanks.

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.
To invert a piecewise affine transform, you'll have to use SciPy KD-tree to
find the nearest quad coordinates, and then invert the matching affine. This
is not necessarily hard, but it's not trivial to implement.
