Issues Running Deepzoom-server.py on Apache (Windows)

Wed Mar 23 14:29:58 EDT 2016

Just to check this further...I am able to verify the same library in my Apache environment in wsgi and I see it...platform.system = Windows
libopenslide-0 was found at: C:\Apache24\bin\libopenslide-0.dll
libcairo-2 was found at: C:\DATA\openslide-win64-20150527\bin\libcairo-2.dllWonder what I am missing.Any help is appreciated.With Regards, Ranga
