[vtkusers] Question about image resampling

[David Gobbi]

Hi Pankaj,

I think that what you want is this:

reslice->TransformInputSamplingOff();
reslice->AutoCropOutputOff();

That should cause vtkImageReslice to automatically produce an output 
with the same spacing, origin, and dimensions as the input, so that you 
will not have to re-resample the output.
