Hi Sina, I just enabled MITK_BUILD_EXAMPLES in CMake, built and run MitkStep1 successfully. To help you out here, we need more information about your setup. We also need to know if it works for you unmodified? By the way, you don’t need all that string handling stuff in your additional code, as mitk::IOUtil::Load() takes a std::string as its first argument – just call mitk::IOUtil::Load(imagePath.toStdString(), *ds).

I guess you are reading an outdated version of our tutorial (which would also explain why you are using the deprecated DataNodeFactory instead of IOUtils). There are some major differences in the current version (MITK 2015.05): http://docs.mitk.org/2015.05/Step01Page.html Do you really want to code your own application from the very beginning instead of just using/extending the full-featured MitkWorkbench? Regarding MITK images in QtWidgets: I found a code snippet in my archive which I wrote a few years ago. I cannot guarantee that it will still work out of the box but you should get the idea of what is necessary to accomplish that task (see it as pseudo code). Maybe Rostislav has a better snippet (as far as I remember he displays images in his widgets, too - added him explicitly to Cc): SNIP ==== mitk::ExtractSliceFilter::Pointer extractSliceFilter = mitk::ExtractSliceFilter::New(); extractSliceFilter->SetInterpolationMode(mitk::ExtractSliceFilter::RESLICE_CUBIC); extractSliceFilter->SetResliceTransformByGeometry(image->GetGeometry()); extractSliceFilter->SetWorldGeometry(planarFigure->GetGeometry2D()); extractSliceFilter->SetVtkOutputRequest(true); extractSliceFilter->SetInput(image); extractSliceFilter->Update(); vtkImageData* imageData = extractSliceFilter->GetVtkOutput(); mitk::LevelWindow levelWindow; imageDataNode->GetLevelWindow(levelWindow); vtkSmartPointer<vtkLookupTable> lookupTable = vtkSmartPointer<vtkLookupTable>::New(); lookupTable->SetRange(levelWindow.GetLowerWindowBound(), levelWindow.GetUpperWindowBound()); lookupTable->SetSaturationRange(0.0, 0.0); lookupTable->SetValueRange(0.0, 1.0); lookupTable->SetHueRange(0.0, 0.0); lookupTable->SetRampToLinear(); vtkSmartPointer<vtkMitkLevelWindowFilter> levelWindowFilter = vtkSmartPointer<vtkMitkLevelWindowFilter>::New(); levelWindowFilter->SetLookupTable(lookupTable); levelWindowFilter->SetInput(imageData); levelWindowFilter->SetMinOpacity(0.0); levelWindowFilter->SetMaxOpacity(1.0); int dims[3]; imageData->GetDimensions(dims); vtkFloatingPointType clippingBounds[] = { 0.0, dims[0], 0.0, dims[1] }; levelWindowFilter->SetClippingBounds(clippingBounds); levelWindowFilter->Update(); imageData = levelWindowFilter->GetOutput(); QImage inspectImage( reinterpret_cast<const unsigned char*>(imageData->GetScalarPointer()), dims[0], dims[1], QImage::Format_ARGB32); inspectImage = inspectImage.rgbSwapped().mirrored(false, true); // Important, don't forget!! m_Controls.inspectLabel->setPixmap(QPixmap::fromImage(inspectImage)); === SNIP ________________________________________ Von: Sina Gerlach [sina.gerlac...@gmx.de] Gesendet: Dienstag, 13.

As I was saying earlier Im using the Tutorial Part1 and all I want to change is the way an image is used. Instead of having it in the command argument thingy I want to open an image using QfileDialog which works but its not displaying the image yet. Heres the source code for clarification: MainWindow.cpp //Construktor Destruktor... void MainWindow::on_openButton_pressed() { // Create a DataStorage mitk::StandaloneDataStorage::Pointer ds = mitk::StandaloneDataStorage::New(); // Create a DataNodeFactory to read a data format supported mitk::DataNodeFactory::Pointer reader = mitk::DataNodeFactory::New(); QString imagePath = QFileDialog::getOpenFileName(this, "Select one or more files to open", "/home", "Images (*.DCM)"); char* filename; filename = new char[imagePath.toStdString().size() + 1]; strcpy(filename, imagePath.toStdString().c_str()); try { reader->SetFileName(filename); reader->Update(); // Add the node to the DataStorage ds->Add(reader->GetOutput()); } catch (...) { fprintf(stderr, "Could not open file %s \n\n", filename); exit(2); } //create render window QmitkRenderWindow *scene; // Tell the RenderWindow which part of the datastorage to render scene->GetRenderer()->SetDataStorage(ds); // Initialize the RenderWindow mitk::TimeGeometry::Pointer geo = ds->ComputeBoundingGeometry3D(ds->GetAll()); mitk::RenderingManager::GetInstance()->InitializeViews(geo); // Select a slice mitk::SliceNavigationController::Pointer sliceNaviController = scene->GetSliceNavigationController(); if (sliceNaviController) sliceNaviController->GetSlice()->SetPos(0); //Show image scene->show(); scene->resize(256, 256); ds = NULL; The QmitkRegisterClasses() Funktion is in main.cpp, but causes the following error when not commented out: error LNK2019: unresolved external symbol "__declspec(dllimport) void __cdecl QmitkRegisterClasses(void)" (__imp_?QmitkRegisterClasses@@YAXXZ) referenced in function main Also, is there a way to have the image show up in a widget of my ui-file (QGraphicsView)?
