[vtkusers] Volume origin,bounds, extent question

[Kall, Bruce A.]

Anybody have any thoughts on my question from the other day?
The only thing I can find in vtkImageReader is the SetTransform
but that has to be a permutation matrix.  I need to rotate/translate.
I've got the transform calculated, I just don't know where to apply it.

Thanks,
Bruce
