[vtk-developers] LookupTable madness

[Prabhu Ramachandran]

hi,

Julian Humphries <julian at essaustin.com> reported this here:

http://public.kitware.com/pipermail/vtkusers/2001-May/006197.html

and I confirmed the problem with both 3.2 and the nightly releases.
No one replied to the reports and I am no expert on this...  I thought
the bug was pretty severe since any color mapping would be inaccurate
if the LuT was messed up?
