[vtkusers] problem with convert itk to vtk

[Роман Глуховский]

 Hi vtkusers,

i load a DICOM-file with itk and after that i would like to display the file with vtk. 

If I compile the programm I have no error. When i start the programm, its crashed and 
i get a return value "0".

In the debug-mode i get a "segmentation fault" and the programm stops at this position

----------> m_Importer->SetPropagateUpdateExtentCallback(m_Exporter->GetPropagateUpdateExtentCallback());

in the "itkImageToVTKImageFilter_hxx". 

Here is my code:

        typedef itk::Image<unsigned char, 3> VisualizingImageType;
        typedef itk::ImageFileReader< VisualizingImageType >  ReaderType;
        ReaderType::Pointer reader = ReaderType::New();
        reader->SetFileName( "DICOM-File" );
        typedef itk::GDCMImageIO ImageIOType;

        ImageIOType::Pointer gdcmImageIO = ImageIOType::New();

        reader->SetImageIO( gdcmImageIO );
        reader->Update();
        reader->GetOutput()->Print(std::cout);

        vtkSmartPointer<vtkRenderWindow> renWin = vtkSmartPointer<vtkRenderWindow>::New();
        vtkSmartPointer<vtkRenderer> ren1 = vtkSmartPointer<vtkRenderer>::New();
        ren1->SetBackground(0.5f,0.5f,1.0f);

        renWin->AddRenderer(ren1);
        renWin->SetSize(1280,1024);
        vtkSmartPointer<vtkRenderWindowInteractor> iren =
            vtkSmartPointer<vtkRenderWindowInteractor>::New();
        iren->SetRenderWindow(renWin);
        renWin->Render(); // make sure we have an OpenGL context.

        typedef itk::ImageToVTKImageFilter<VisualizingImageType> itkVtkConverter;
        itkVtkConverter::Pointer conv=itkVtkConverter::New();
        conv->GetExporter()->SetInput(reader->GetOutput());
        conv->GetImporter()->Update();
        conv->GetImporter()->GetOutput()->Print(std::cout);

        vtkImageViewer * viewer =vtkImageViewer::New();
        vtkRenderWindowInteractor * renderWindowInteractor =
        vtkRenderWindowInteractor::New();
        viewer->SetupInteractor( renderWindowInteractor );
        viewer->SetInputData( conv->GetImporter()->GetOutput() );
        viewer->SetZSlice( 0 ); // <-- Slice selection
        viewer->Render();
        renderWindowInteractor->Start();

        viewer->Delete();
        renderWindowInteractor->Delete();
        conv->GetImporter()->Delete();


Thank you for your help
