Is there a transformer that can easily define transformation parameters for affine transformation.
What I do have is set of points with old coordinates and same set of points in new coordinates. Can this be used to compute affine transformation model.
Does it concern a rotation scaling? If so, you can use the Affiner.
If you just need to 'Translate' the data, the Offsetter will probably do what you want to achieve.
You will need to calculate the values based on one or more coordinate pairs.

Yes, I do have rotation and translation. I'd use Affiner but I don't know how to calculate parameters for it.

OK, I understand. What if you create lines between two coordinate pairs (new and old) and you put these lines as control vectors into the AffineWarper?
If it turns out not to be an affine transformation, you could also use the Rubbersheeter.

AffineWarper does the trick. Thank you
