using an existing DLL file without having access to the source code?

[Dieter Vanderelst]

Dear all,

Could anybody tell me whether there are ways to use an existing DLL file 
in Python without having access to the source code?

I'm trying to find a way to use the image filters available in the 
Filters-project (http://filters.sourceforge.net/) without having to 
compile or build the DLL myself, which is according to the authors very 
hard.

I have quite some experience with Python itself, but I'm not really 
familiar with extending/embedding Python, please bare that in mind when 
responding :).

With kind regards,
Dieter
