[MapServer-users] Layer is opaque

[Rahkonen Jukka]

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.
