[Insight-users] itkVTKtoITKtoVTK modification

[Mathieu Lamard]

Thanks Pieter,
  but I want to use a vtkReader and not a itk image reader and that's 
why a try to modify the itkVTKtoITKtoVTK example.
In fact I want to use a vtk for reading images + mouse interaction ... 
ant itk for image filtering.
