[vtkusers] How get DICOM image intensity?

[Jim Peterson]

I think GetScalarPointer returns an address of the scalar that still 
needs to be dereferenced according to the scalar type for the image.

I googled  - vtk getscalarpointer - and the class reference is pretty 
complete. you probably need to use GetScalarType to determine how to 
cast the pointer from  GetScalarPointer to dereference the value.
