Dear VTK users, I would like to understand which is the relations between the contour value fixed reading image in 16 bit utilizing VTKVolume 16 reader and the contour value that I can fix using the vtkBMPreader. I mean the contour value 500 using vtkVolume 16 reader, to which value corrispond using vtkBMPreader? Thanks a lot to alla of you! Dario
