[vtkusers] grey values from CT scan

[Mathieu Malaterre]

Viral,

	Here is a python code:

reader = vtkVolume16Reader()
...
reader.Update()
print reader.GetOutput().GetScalarRange()
#print pixel value:
print reader.GetOutput().GetScalarComponentAsFloat(0,0,0,0)

HTH

Ps: I am not sure I understood what you meant by 'threshold value' ??? 
Therefore I translated it to scalar range...
