[vtkusers] fit to screen in vtkImageViewer2 + QVTKWidget

[K O ranjith]

Thanks for the solution,
One more doubt in my application, vtkDICOMImageReader is used for reading
all the DICOM files in a folder and setting directly to vtkImageViewer2
 through SetInputConnection(reader->GetOutputPort());. The DICOM images in
the folder might have different size. In this case how can get "Extent"
"Orgin" "spacing" parameters of each image.
Have any methods to extract these from  vtkDICOMImageReader  or vtkImageViewer2
?
