[mapserver-users] MapServer + SLD + transparency

[Oscar Gomez]

Hi all!

I'm having some trouble trying to use SLDs with MapServer.

I'm requesting maps from GoogleEarth using a NetworkLink object and a custom
KML-WMS-KML parser.

If I apply "simple" symbology through a custom SLD, it works, and the
background of the map created by MapServer is transparent, so only the
"vectors" are shown in GoogleEarth.

But if I use an SLD symbology using an external picture (<ExternalGraphic>
tag in SLD), then the background of the map created by MapServer is not
transparent anymore. Then Google Earth shows a map with white background.

Has anyone experienced the same? Can this be solved?

Thanks in advance,

Oscar
