[vtkusers] Can any body help!

[Marc Cotran]

Hi Saira,

This is a common problem, and you can most likely find other threads on 
the mailing list for it.

You have two options here. One is to use a mapper that supports the 
short data type (eg. vtkFixedPointMaper) and pass your data as is. The 
other is change the data's scalar type and then use the ray cast mapper. 
To change the scalar type without compromising the range of your data, 
take a look at vtkImageShiftScale.
