PyIStream and COM question for WinGraphViz

[Simon Frost]

Dear Python List,

I'd like to write a COM interface to WinGraphViz 
(http://home.so-net.net.tw/oodtsen/wingraphviz/). I would like to dump my 
image to a PyIStream, but I can't find any documentation on how to do this.

Here's the syntax for the COM interface

ProgramID: WinGraphviz.BinaryImage
  Dump(IStream stream) as Boolean

I would like to do something like
istream=PyIStream(...)
myBinaryImage.Dump(istream)

and then go on to display the image.

Any help would be greatly appreciated.

Best
Simon
