[MapProxy] Not loading images ("PIL is not available")

Tue Jul 10 09:28:36 PDT 2012

Hi, just following up on this.

I resolved this problem with PIL by using a different binary version from:

http://www.lfd.uci.edu/~gohlke/pythonlibs/

Other versions, including versions installed via python itself and the binaries found at http://effbot.org/downloads/#pil simply did not work.

I thought I'd post in case someone else runs into the same problem.  I would also include in the docs the a write-up on how to get it working with IIS.  I'd do so myself, but it is outside the scope of the job that caused me to submit the ticket in the first place.

Regards,

Paul

Subject: [MapProxy] Not loading images ("PIL is not available")

Hi there, I'm having troubles loading any images from the mapproxy demo WMS.  The machine is a Win2k8 R2 server with apache 2.2, python 2.7.3 and associated tools installed.  I confirm that PIL is installed and importable from the python shell.  To hedge my bets I even reinstalled using the exact procedure on the site.  Since I'm using mod_wsgi, I did not put it in a virtualenv, per the instructions.

The error I keep getting the following errors in my apache below:
