[vtkusers] accessing a subregion of vtkImageData

Hi vtk-users,

I'd like to access a subregion of my vtkImageData (512x512x181). So far I have 
used the vtkExtractVOI-class for that purpose. However, this class creates a 
copy of the subregion and therefore increases my application's memory demand.

Is there a way to avoid this by using pointers to the subregion ?

Many thanks in advance,
Regards,
Steffen Oeltze
