[vtkusers] ActiViz | Changing Window Level and Window Width in a RenderWindowControl

[Matias Montroull]

I made it work!

     interactor.Initialize() is the key..

Code:

                    vtkImageViewer2 _ImageViewer = vtkImageViewer2.New();
                    vtkDICOMImageReader reader = vtkDICOMImageReader.New();
                    reader.SetFileName(ofdmulti.FileNames[0]);
                    reader.Update();
                    _ImageViewer.SetInputConnection(reader.GetOutputPort());
                    vtkRenderWindow renderWindow =
renderWindowControl1.RenderWindow;

                    vtkRenderWindowInteractor interactor = new
vtkRenderWindowInteractor();

interactor.SetInteractorStyle(vtkInteractorStyleImage.New());
                    _ImageViewer.SetupInteractor(interactor);
                    interactor.Initialize(); //This is ke, if not added
then WW and WL functionality won't work.

                    _ImageViewer.SetRenderWindow(renderWindow);
                    _ImageViewer.Render();
