[vtkusers] FillComponent and GetScalarRange

[O'Connor, Aonghus]

Hello all,
I have been using vtk and itk for some time. It's pretty useful.
Question:

I have imported some data from a DICOM series and I want to fill the whole
region with a particular scalar value:

ImageImport.GetOutput().GetPointData().GetScalars().FillComponent(0, val);
ImageImport.UpdateWholeExtent();
double [] range = ImageImport.GetOutput().GetScalarRange();

The scalar range is (-1024,2000) but does not change after I fill the
region.

Why does the scalar range not change to (0.0,0.0) ?

Regards,
Aonghus
