[Paraview] blank screen,

[Battalgazi YILDIRIM]

Hi,

I tried to write  png file (view.WriteImage("image.png", "vtkPNGWriter",1)
), and I got following error

Warning: In
/home/yildirim/projects/ParaView3/Servers/ServerManager/vtkSMRenderViewProxy.cxx,
line 1110
vtkSMIceTDesktopRenderViewProxy (0x2630390): Disabling offscreen rendering
since empty image was detected.

and image is blank too (visualized with gimp)

Thanks,
