My 2DView Pipeline.. vtkVolume16Reader -> vtkImageReslice -> vtkTransform -> vtkImageMapper -> vtkActor2D -> vtkRenderer -> vtkWin32OpenGLRenderWindow -> vtkWin32RenderWindowInteractor...... But, this pipeline does not discharge interactor.(zoom, pan, etc...) I want to control WindowLevel and WindowWidth. Plz..... How should you do it?
