[vtkusers] about save file

[胡 小娟]

  In VTK versions , the vtkWindowToImageFilter class is part of the 
canonical way to output an image of a window to a file (replacing the 
obsolete SaveImageAsPPM method for vtkRenderWindows that existed in 3.2 and 
earlier). We should connect one of these filters to the output of the 
window, and filter's output to a writer such as vtkPNGWriter.
   But there is not vtkPPMWriter,How can I save vtkRenderWindows as as PPM 
file?
