[vtkusers] vtkScalars from vtkImageData

[amit saxena]

Hi,
  I am trying to make a volume from a number of
images. I read the data using vtkVolume16Reader. When
I display the images using vtkImageViewer I get the
images, but as soon as I try to get the pointer to the
scalars I get the memory location as 0x000000 and
hence an access voilation. I am doing something like
this :

    vtkImage data = vtkImageData::New();
    ...
    ...
    vtkScalars *scalars =  
data->GetPointData()->GetScalars();

  Where possibly am I going wrong ? 

AMIT
