[vtkusers] Centigrade scalars to Fahrenheit scalars

[Kenn Lin]

Hello, world:

If now I get a vtk data file containing centigrade scalars, how can I
transform them to Fahrenheit scalars with out changing the data file
itself? I mean, is there any way to change the scalar values in the
pipeline by bringing in formula?

Thanks in advance :)
