[vtkusers] Settings of VtkScalarBarActor

[Geoframer]

Fracois,

The vtkLookupTable has a method called SetTableRange. With this method you
can set the range of your lookup table and this will be visualised in your
scalar bar.
So your solution would be :

LuT.SetTableRange 0 256

Ofcourse this 'solution' does not take into account how you build your
lookuptable or what values it presents...

Regards - Geofram
