Hi,

I'm new to Mapnik and I want to render the population example 
(http://trac.mapnik.org/wiki/XMLGettingStarted) once with the Cairo renderer 
and once with AGG -> that's already working, but the main problem is that I 
want to show the rendered files in the webbrowser by just makeing an wms server 
request, but when I try this the file is just saved on the disk and nothing is 
shown in the web browser. I thought maybe the xml_factory.py is the solution, 
but when I try to run it with the population.xml file I get nothing. I've 
checked this patch but I have the latest developer source so I didn't change 
anything (if I have to change anything - how? just editing the WMS.py and 
common.py in a directory like this: 
/usr/lib/python2.6/site-packages/mapnik/ogcserver/WMS.py ?) .

Do you have any idea how am I able to show the pictures in the webbrowser with 
a single wms request (especially that shows the Cairo rendered file in 
webbrowser).


Heres the code of the xml_factory.py:

from mapnik.ogcserver.WMS import BaseWMSFactory

# note, this class for loading an xml map requires patch from 
http://trac.mapnik.org/ticket/129

class WMSFactory(BaseWMSFactory):
  def __init__(self):
    BaseWMSFactory.__init__(self)
    self.loadXML('/Users/spring/mapnik/osm.xml')
    self.finalize()

 

best regards,

Martin
