#include <vtkKWEITKImage.h>
This class provides seamless conversion from VTK to ITK images and vice versa. Specifically, you can set an ITK image (itk::Image< T >) and get the corresponding VTK image (vtkImageData), or a binarized stencil image (vtkImageStencilData). You can also go the other way around.
