Its a filter just like any other filter.

	m_WLFilter = vtkImageMapToWindowLevelColors::New();
	m_WLFilter->SetOutputFormatToLuminance();
	m_WLFilter->SetInput( reader->GetOutput());
        m_WLFilter->SetWindow(1000.0);
	m_WLFilter->SetWindow(400.0);
	m_WLFilter->UpdateWholeExtent();


        vtkImageActor *actor = vtkImageActor::New();
        actor->SetInput(m_WLFilter->GetOutput());

Probably every single person who views a 2 byte per pixel DICOM image with vtk..
