 I want to put transparency on polygon layer so that aerial photo could be seen below it. I have tried TRANSPARECY and OPACITY but i only get faded not transparent layer. My imagetype is PNG. Here is the mapfile

    DRIVER GD/PNG
    IMAGEMODE RGBA
    EXTENSION "png"
    FORMATOPTION "FULL_RESOLUTION=TRUE"

    TRANSPARENT ON
    END #end outputformat
 #IMAGETYPE PNG

    END

     END
    END
  END
END
