yes but with jpeg, the pixels range from 0 to 255, with dicom from -1000 
(sometimes -3000) to 1000 or more.

they are not identical, the jpeg come from the brodatz collection, the
dicom are lung CT.

If I change the pixel type from short to unsigned char, the values seem
to be ok for the jpeg. But then I cannot deal with the dicom (all pixels
are trunkated to the 8 lesser bits.)

Question: what should I put in SetPixelMaximumMinimum() ? I mean, if
I want my soft to deal both type of images?
