I met some problem while using the image writing function in VTK. I
write in TCL running on a Win 2000 platform. Could somebody point out a
solution for me?

My TCL script is:

vtkRenderer ren1
vtkRenderWindow renWin
    renWin AddRenderer ren1
ren1 Render

vtkWindowToImageFilter w2i
	w2i SetInput renWin
vtkJPEGWriter writer
	writer SetInput [w2i GetOutput]
	writer SetFileName "c:\\zhan\\test.jpg"
	writer Write

the error message is attached in this email as "error.gif"

Thank you for reading this email.
