Hi dario!!!!

You have now a 16 bits image and you can see only 8 bits....
So you should use vtkImageShiftScale to look to an 8 bits grey window....
you have to use the SetScale method :

vtkImageShiftScale* scale = vtkImageShiftScale::New();

N should be 256....else you should try other values (16) if data have in
fact 12 bits... But I think it should be 256!

Dear VTK User,
I'm trying to make function the medical examples, using some slices obtained
from CT scanner, I converted the images with Adobe Photoshop, in gray scale
and after in 16 bit, and I saved it in raw format.
When I make running the program, I can see only a white box, why?
Somebody can help me???
