[vtkusers] vtkImageViewer settings for binary image

[Siddharth Srivastava]

Hi everyone,
     How should I deduce SetColorWindow and SetColorLevel settings for a
binary
image (just 0 and 1)? I am able to view the full range gray scale images (0
to 255),
but I get an empty window for images with just 0 and 1. I have checked the
data in Matlab, and can display it
within Matlab, so the data is ok.
     Generally, what do the functions SetColorWindow and SetColorLevel do
with the
data in the image?
      Thanks,
       Sid.
