[vtkusers] Get pixel intensity

[Andres Munarriz]

Hi everyone,

I'm pretty sure someone has already posted a similar question if not  
the same (for this I apologize), but I haven't been able to find such  
post.  Is there a way to retrieve the pixel intensity at a particular  
index from a vtkImageData object?  Under ITK one can " make" the  
index then get the pixelData from it.


Thanks in advance,
