I am new to GIS technology. I have configured a map server OSGEO4W. I am able to render maps using WMS and openlayers. But the rendering is very slow.
For faster rendering I want to use Mapproxy. I have installed Mapproxy with Python virtual environment. Mapproxy service is running fine. I am checking it with the following url "http://"mylocalhost":8080/" Then, it is showing:
"Welcome to MapProxy 1.5.0"
I have changed the mapproxy.yaml as per the demo application file so that it shows its "demo" application. When I am browsing demo application and rendering map using EPSG:4326 or EPSG:900913 (even when I am using it in my application with openlayers and map file, then also it is showing the the following):
It is showing a blank image. It is showing the following error on command window:
File "c:\mapproxy_venv\lib\site-packages\pil-1.1.7-pu2.7-win-amd64.egg\Image.py" line 385, in _getdecoder raise IOError("decoder %s not available" % decoder_names) IOError: decoder zip not available
It means it does not receive "decoder zip".
Please help me to fix this problem.
