Hi Andreas,
Thank you for your answer.
I got the transformation tMatrix with IndexToWorldTransform of the
movingImage node in debug mode after clicking on the button 'save project'.
However, I figured out that the rotation matrix is transposed- is it true?
The translation vector in that matrix does not reproduce MITK's saved image
and I'm wondering how should I find that translation.
You've suggested with offset/origin, do you mean that from the same point
that I extract tMatrix- to find the offset/origin (with getOffset etc.) and
this is the right translation of the transformation matrix?
Actually I tried to do that and didn't succeed to reproduce MITK's saved
moving image -
I think that a further calculation is required- am I right?
what do you think?....
