[vtkusers] Which class can provide setting window width and window center function?

[jiang]

Dear VTK users,
I have an image which is signed short type. If I want to display it as a
grayscale [0,255], I should cast it to unsigned char type. I know setting
different window width and window center to the image will get different
result. It could be light or dard, show some details or not. I want to know,
is there a such function in VTK so that I can set window width and window
center easily?

Thank you very much!
