[mitk-users] Qmitk Renderwindow

[Sina Gerlach]

Hello,

I'm trying to open a Renderwindow and display a Dicom image using QFileDialog, which doesn't work.

Theres also another Part where I try displaying a dicom image in a QGraphcsview/QLabel. 

Heres my Code for clarification: 

 

void MainWindow::on_openButton_pressed()
{
    QString imagePath = QFileDialog::getOpenFileName(
        this, tr("Open File"),
        "",
        tr("DICOM(*.dcm);;JPEG(*.jpg)")
        );

    imageObject = new QImage();
    imageObject->load(imagePath)
        image = QPixmap::fromImage(*imageObject);

 

        //..using GraphicsView
        // This only works with JPG not Dicom! (mit Slider/unverzerrt)
        scene = new QGraphicsScene(this);
        scene->addPixmap(image);
        scene->setSceneRect(image.rect());
        ui->ViewCoronal->setScene(scene);

 

//..using QLabel
    // This only works with JPG not Dicom! (verzerrt)
    if (image.load(imagePath))
    {
        QPainter painter(&image);
        painter.setPen(Qt::red);
        QRectF rect(100, 100, 100, 100);
        painter.drawRect(rect);
        QSize bigsize = ui->label->size();
        ui->label->setPixmap(image.scaled(bigsize, Qt::IgnoreAspectRatio, Qt::FastTransformation));
        ui->label->show();

 

    //MITK approach
    // Register Qmitk-dependent global instances
    QmitkRegisterClasses();

    //Create a DataStorage
    mitk::StandaloneDataStorage::Pointer ds = mitk::StandaloneDataStorage::New();

 

    //Load datanode (eg. many image formats, surface formats, etc.)
    std::string current_locale_text = imagePath.toLocal8Bit().constData();
    mitk::IOUtil::Load(current_locale_text, *ds);

 

    // Tell the RenderWindow which (part of) the datastorage to render
    QmitkRenderWindow renderWindow;
    renderWindow.GetRenderer()->SetDataStorage(ds);

 

    // Initialize the RenderWindow
    mitk::TimeGeometry::Pointer geo = ds->ComputeBoundingGeometry3D(ds->GetAll());
    mitk::RenderingManager::GetInstance()->InitializeViews(geo);
    //mitk::RenderingManager::GetInstance()->InitializeViews();

 

    // Select a slice
    mitk::SliceNavigationController::Pointer sliceNaviController = renderWindow.GetSliceNavigationController();
    if (sliceNaviController)
        sliceNaviController->GetSlice()->SetPos(0);

    renderWindow.show();
    renderWindow.resize(256, 256);

}

Is there a way to initialize the Renderwindow that it works (I think it doesn't work because its not in main())?

Regarding the QGraphicsview/QLabel: I've seen here that its possible: http://stackoverflow.com/questions/18488050/interactively-editing-an-existing-rectangle-on-a-qpixmap?lq=1

Do I need a Plugin or anything else to make this work?

 

Thank you!

Best Regards

Sina
