PyIStream and COM question for WinGraphViz

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.Bin aryImage
Dump(IStream stream) as Boolean

I would like to do something like
istream=PyIStre am(...)
myBinaryImage.D ump(istream)

and then go on to display the image.

Any help would be greatly appreciated.

Best
Simon
