[vtkusers] Stretching histogram

[Michnay Balázs]

Hi,

I'm still trying to figure out how to contrast enhance an image (or 
stretching its histogram). 

I found out that using the class vtkImageMapToWindowLevelColors 
might be helpful but I could not figure out how to use it. Is there a way 
to enhance my image "automatically"? Or do I have to adjust 
SetWindow/SetLevel manually every time the contrast is not correct?
Thanks for your help,

Michnay
