Order of transformparameter files when computing inverse

[kenrickschulze]

Hello :)

i want to create an inverse transformation, thus i followed the example in "ITK_Example11_Transformix_DeformationField.ipynb".
I was wondering why the inverse transform ParameterObject is not initialized in the inversed order to the originally created tx,
e.g. i thought the inverse transform must be : inv_tx = affine(bsline(x))

I tested in binder if it makes any difference. The resulting deformation fields look similar but are not similar numerically.

So, does it make any difference what i create as ParameterObject() and what order would be technically correct?
Any clarification would be very appreciated :)

I attached my modifications of ur example for easy reproduction.
