Hi list,
I am using mapserver to provide a wms service. I would like to set a
transparency value for a layer to 50. The final map provided don't use the
right opacity for this layer. This layer is always 100% opaque.
Is it possible to change the transparency for a layer using WMS?
The transparency (or opacity on 5.0) setting applies only between layers
within a given map draw, but the resulting map image is always opaque
(unless you pass TRANSPARENT=TRUE in a GetMap request, in which case
only the background color is transparent).
If you have a mapfile with multiple CONNECTIONTYPE WMS layers then
setting transparency/opacity between those layers should work.
If you are using MapServer as a WMS service and expecting the
transparency/opacity of a given layer to result in a 50% opaque GetMap
response then that won't work.
