[Geoserver-devel] Setting fill color of polygon to transaparent (Not White)

Hi,

I am trying to set the fill colour of a polygon to be transrarent so that
the raster layer below shows through. My layer is a shape file (outline of
county borders) which sits on top of Ordanance survey raster maps.
Unfortunately at the moment if i change the css opacity value all it does is
change to white... any suggestions?

Thanks

Paul

Odd. Are you requesting the image in a format like JPEG, that does not
support transparency? Are you adding &transparent=true to your requests?
Normally all that needs to be done is not to specify a Fill at all
in the SLD.

Hi,
Thanks for your reply. The image is a png, however i am not adding
&transparent=true to the request no. Could you tell me where i am supposed
to add that?

Thanks
