[Insight-users] Problem using ImageToVTKImageFilter and QVTKWidget

[jason yuan]

Hi Luis and Françoise,

I met the same problem in the new version of itk (3.20), but it seems to
have fixed at 2010-10-21, can somebody tell me how to get a stable version
which can solve this problem?

Thank you in advance, it bother me for quite a few days.
Below is my source code.

    QString fileName = QFileDialog::getOpenFileName(this,
        tr("Open Image"), "c:/", tr("*.*"));
    typedef itk::Image<unsigned short,2> ImageType;
    typedef itk::ImageFileReader<ImageType> ReaderType;
    typedef itk::ImageToVTKImageFilter<ImageType> ConnectorType;
    ReaderType::Pointer readerITK = ReaderType::New();
    readerITK->SetFileName(fileName.toLocal8Bit().constData());
    ConnectorType::Pointer connector = ConnectorType::New();
    connector->SetInput( readerITK->GetOutput() );
    vtkImageData* vtkimage = vtkImageData::New();
    connector->Update();
    vtkimage = connector->GetOutput();
    vtkImageViewer* viewer = vtkImageViewer::New();
    viewer->SetInput(vtkimage );
    ui->qvtkWidget->SetRenderWindow(viewer->GetRenderWindow());
   
viewer->SetupInteractor(ui->qvtkWidget->GetRenderWindow()->GetInteractor());
    viewer->Render();
    viewer->SetColorWindow( 254 );
    viewer->SetColorLevel( 128 );

BR,
Jason
