I have defined the following two function, how can I read the TransformParameterMapand transformixImageFilter results? for example rotation results of moving image or generally all the results related to transformation or translation or angel?

I do have histopathology images which they cannot match well after using the non-rigid or rigid transformation. I just wanted to see the transformation matrix and play a little bit with them to see if I can somehow work further
