Hi Dan,

Thanks for your reply and putting me in the right track.

It turns out that there is an example in ITK to decimate a volume, in 
Examples/Filtering/SubsampleVolume.cxx.

It uses IdentityTransform, as you suggest, although prior to resampling 
it uses a low-pass filter to avoid aliasing.

Best regards,

Ramon.
