[vtkusers] SetDataSpacing = SetSpacing ?

[Chris Turner]

Hi,

I noticed that in the Medical4 example the spacing of the CT Image is
set in the vtkVolume16Reader object with the method SetDataSpacing. If
I want to change the spacing of the CT Image after I loaded it can I
do that with the SetSpacing method on a vtkImageData object? Do those
have the same effect?

Because for some reason changes at the spacing of the vtkImagaData
seems to have no impact on the displyed rendered volume...

Anybody knows why?

Thanks
Chris
