[vtkusers] JPG file

[Renato Cesar Pompeu]

I had seen this example before and I'm trying to do something equivalent to the Borland but is not working. Any ideas?

 

...

vtkSphereSource *sphereVmax = vtkSphereSource::New();
    sphereVmax->SetThetaResolution(15);
    sphereVmax->SetPhiResolution(15);
    sphereVmax->SetRadius(0.5);


 

vtkPolyDataMapper *sphereMapperVmax = vtkPolyDataMapper::New();
    sphereMapperVmax->SetInput(sphereVmax->GetOutput());
    sphereMapperVmax->ImmediateModeRenderingOn();

 

vtkActor *sphereActorVmax = vtkActor::New();
    sphereActorVmax->SetMapper(sphereMapperVmax);
    sphereActorVmax->GetProperty()->SetColor(0.9, 0.6, 0.1);
    sphereActorVmax->GetProperty()->SetAmbient(0.2);
    sphereActorVmax->GetProperty()->SetDiffuse(0.3);
    sphereActorVmax->GetProperty()->SetSpecular(0.8);


 

VTK->GetRenderer()->AddActor(sphereActorVmax);    // (VTK is a BorlandRenderWindow) 


 

vtkWindowToImageFilter *image = vtkWindowToImageFilter::New();
        image->SetInput(VTK->GetRenderWindow());    // (I know the problem is here, but I can not solve it)
        image->SetMagnification(6);
        image->Update();

 

vtkJPEGWriter *png = vtkJPEGWriter::New();
        png->SetFileName("screenshot.jpg");
        png->SetInput(image->GetOutput());
        png->Write();

...


Thanks again.
