[vtkusers] VtkWindowToImageFilter or Renderer cutting resolution

[robertklimt]

Hi,

I have a problem with generating image from my scene, when size of the
rendering window is bigger than my screen resolution. 

imageViewer.GetRenderWindow().SetSize(1024,1024);

then using VtkWindowToImageFilter to get image gives me image smaller than
requested(about 1024 x 885) for 1440x 900 screen resolution.

Is there any way to render full scene?
