[vtkusers] DICOM image display on MFC picture control using VTK

[Kiran Gachchi]

Hi All,

I have created an application in Visual C++ using VTK and MFC.

I want to display DICOM images on MFC picture control using VTK.

I wrote the following snippet for the same:

                             Viewer ->SetInput(vtkImageData);
                             Viewer ->SetupInteractor(MFCWindow ->GetInteractor());
                             MFCWindow->SetRenderWindow((vtkWin32OpenGLRenderWindow *)Viewer->GetRenderWindow());
                             MFCWindow_Ref->GetRenderWindow()->GetInteractor()->SetInteractorStyle(InteractorStyleImage);
                             Viewer_Ref->SetColorLevel(400);
                             Viewer_Ref->SetColorWindow(1500);
                             Viewer_Ref->GetRenderer()->ResetCamera();
                             Viewer_Ref->Render();

I am able to display DICOM images using this code.
But the problem is I need to look at the DICOM image header for window level(400) and window width(1500).
How to automate this?
And for some DICOM images, window level and window width from the header doesn't work out. I need to give some other values to display them properly.

Could anyone help me out to overcome this problem??

Thanks in advance.

Regards,
Kiran
