WMS-Transparency (?)

[Bart van den Eijnden (OSGIS)]

You should be able to do this by using an SLD. Try something like (not
verified!):

"wms_sld_body" "<StyledLayerDescriptor version='1.0.0'
xmlns='http://www.opengis.net/sld'
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xsi:schemaLocation='http://www.opengis.net/sld
http://schemas.opengeospatial.net/sld/1.0.0/StyledLayerDescriptor.xsd'><NamedLayer><Name>YOURLAYERNAME</Name><UserStyle><FeatureTypeStyle><Rule><RasterSymbolizer><Opacity>0.5</Opacity></Rule></FeatureTypeStyle></UserStyle></NamedLayer></StyledLayerDescriptor>"

Change YOURLAYERNAME into the name of your layer (wms_name).

Hope this helps.

Best regards,
Bart
