+ * \brief Converts a VTK image into an ITK image and plugs a 
+ *  vtk data pipeline to an ITK datapipeline.   
+ *
+ *  This class puts together an itkVTKImageImporter and a vtkImageExporter.
+ *  It takes care of the details related to the connection of ITK and VTK
+ *  pipelines. The User will perceive this filter as an adaptor to which
+ *  a vtkImage can be plugged as input and an itk::Image is produced as 
+ *  output.

+ * \ingroup   ImageFilters
