"I don't know if it is possible at the map level..." - It's not, opacity is a layer or style-level parameter. For opaque maps many of the client environments (e.g. OpenLayers) provide controls for such things. In that case I would think it's better to use the client support than produce RGBA output via MapServer...

Hi Clément,
To change layers opacity in cgi call, something like that should work :
http://yourServer/cgi-bin/mapserv?map=yourMapfile&map.layer[yourLayerName1]=OPACITY%20yourOpacityValue1&map.layer[yourLayerName2]=OPACITY%20yourOpacityValue2
I don't know if it is possible at the map level...
Regards,
Olivier.

Hi,
Is it possible to set layer's opacity dynamically ? with runtime substitution ?
is there a way to set opacity for all layers of a mapfile ?
Thank you for your help
Clem
