Hi,
Work for me in two different ways with this test layer
LAYER
NAME "layername"
TYPE POLYGON
FEATURE
POINTS 10 5 15 10 5 10 10 5 END
END #feature
# opacity defined with COMPOSITE
COMPOSITE
OPACITY 70
END # COMPOSITE
METADATA
'wms_title' 'layername'
"wms_srs" "EPSG:4326"
END #metadata
CLASS
STYLE
#alternatively opacity defined in style
#OPACITY 80
COLOR 210 155 100
END #style
END #class
END #layer
The outputformat must be png, jpeg does not support opacity/transparency.

I am trying to use mapserver to display some data but unfortunately the map in
not visible below the layer. My configuration of my mapserver is below. Any
guidance would be appreciated.
