[vtkusers] vtkImageViewer2 with QVTKWidget

[Luca Pamparana]

Hi everyone,

So I cut down the code but still cannot display a DICOM image inside of
vtkImageViewer2 object. The normal vtkImageViewer works fine.

Here is the updated code:

QApplication app(argc, argv);

QVTKWidget widget;

#if QT_VERSION < 0x040000
    app.setMainWidget(&mainWin);
#endif

vtkDICOMImageReader *reader = vtkDICOMImageReader::New();

reader->SetDirectoryName("/home/luca/data/dicom/11088");
reader->Update();

vtkImageViewer2 * view2 = vtkImageViewer2::New();
view2->SetInputConnection(reader->GetOutputPort());

double * range = reader->GetOutput()->GetScalarRange();
view2->SetColorLevel (0.5 * (range[1] + range[0]));
view2->SetColorWindow (range[1] - range[0]);

widget.SetRenderWindow(view2->GetRenderWindow());

// Put these 2 lines....just in case...
view2->SetSlice(0);
view2->GetRenderer()->ResetCameraClippingRange();

view2->Render();

widget.show();

// Run our application loop.
app.exec();

I really am lost as to why it would not show me the image. Again,
substituting vtkImageViewer2 with vtkImageViewer works fine. Is there some
trick with the camera or the renderer that I am forgetting??? I am running
SuSe 10.1 on a 64 bit machine.

If someone can try this code and let me know if it works on their machine,
it would be great.

Cheers,

Luca
