[vtkusers] problem rendering

[Lucas Lorenzo]

Hi all,

I'm trying to run this simple code (I'm pasting only the important 
parts):


				.
				.
				.

  // Create the RenderWindow, Renderer and both Actors
   vtkRenderer *ren1 = vtkRenderer::New();
   vtkRenderWindow *renWin = vtkRenderWindow::New();
   renWin->AddRenderer(ren1);

   // Add the actors to the renderer, set the background and size
   ren1->AddActor(imActor);
   renWin->SetSize(640,640);

   // render the image
   vtkCamera *cam1 = ren1->GetActiveCamera();
   cam1->Zoom(2.5);
   renWin->Render();

   // deallocate memory:
   image_reader->Delete();
   lut->Delete();
   get_slice->Delete();
   im_mapper->Delete();
   imActor->Delete();
   ren1->Delete();
   renWin->Delete();

   return 0;
}

The problem I have is that the window pops up, shows the image I want 
to render but then immediately it closes.
What am I missing so that the renderer window doesn't close ?
Thanks,

Lucas
