[cairo] Rendering SVG with libRSVG, Python ... CTYPES SUCCESS AT LAST!!!

Thanks for your advice Gerdus, but I have tried your suggestion with no 
success. It has at least been beneficial to discover a tool which I did 
not know about in 'Dependency Walker'; all dependencies appear okay.

searching through my 'C:WINDOWS\system32' directory I discovered a 
subdirectory named 'rsvg' containing a number of .dll's associated with 
that library, including the ones I was attempting to load. I'm not 
certain how it got there; I probably added it myself sometime in the 
last couple of weeks in a vain attempt to solve the problem. In any 
case, that directory seems to have been the root of my problems causing 
some path conflicts, since when I deleted it my code ran fine! At last, 
"l = CDLL('librsvg-2-2.dll')" works! Now to give the rest of your 
solution a try...

Best regards,
