Hello Genis,
That is great news that upgrading fixed the problem.

Hello,
Thanks for the feedback :)
With mapnik version 6.0.0 the code doesn't work, but with 6.0.1
version everything works OK :)
kind regards,

Hmm,
That is odd, it works fine for me. I don't have time to test your
setup, but I modified the examples at:
http://mapnik-utils.googlecode.com/svn/example_code/wms
to include transparent tiles for the labels.
See the OpenLayers example here:
http://mapnik-utils.googlecode.com/svn/example_code/wms/
openlayers.html
See the mapfile here:
http://mapnik-utils.googlecode.com/svn/example_code/wms/population.xml
And the 'map_factory' here:
http://mapnik-utils.googlecode.com/svn/example_code/wms/xml_factory.py
I ran the server in python standalone mode using:
python localogc.py # from:
http://mapnik-utils.googlecode.com/svn/example_code/wms/localogc.py
Does that work for you?
If not, can you confirm your mapnik version and maybe post a bit of
sample data?

Hello,
I've put the code for the mapnik wms here: http://dpaste.com/104816/
I call it from Openlayers with this function:
var baselayer = new OpenLayers.Layer.WMS( "Base layer","http://localhost:9012
", {layers: 'shire}, {'displayInLayerSwitcher':true} );
var layer = new OpenLayers.Layer.WMS( "UTM grid 10x10","http://localhost:9012
", {layers: 'UTM10X10',transparent:'TRUE'},
{'isBaseLayer':false,'displayInLayerSwitcher':true} );
map.addLayers([baselayer,layer]);
IF I add the parameter 'transparent': TRUE, the background is
black, if I don't then it's white.
Is it possible to get a transparent background using mapnik's
ogcfeatures?
kind regards,

Hello Genis.
I think the way the WMS spec works to request a tranparent
background tile you need to set up OpenLayers to send
TRANSPARENT=true as one of you getMap request parameters. This is
not the way Mapnik works but how the OgcServer implementation works.

Hello list,
I've created a wms service using mapnik with 2 layers.
One is being used as the base layer (using openlayers) and the 2nd
one is a switchable layer on top of that (it displays a UTM grid).
The problem appears to be that the backgound of the 2nd layer (a
grid) is color white instead of transparent, so it renders on top
of the base layer...
I know I can set the opacity of the polygon to 0, but how can I set
the background of the map to transparent?
Kind Regards,
G
