[mapserver-users] Re: contours in mapfile

Hi Jeff, Gregory and Everyone,

First, thanks for the useful answers. I succeed now in displaying a
nice filled contour image.

My question is now - how can I make contours nicely draw as line.
Meaning - no fill, just out line.

I tried with:
    CLASSITEM "[pixel]"
    CLASS
        NAME "NO DATA"
        EXPRESSION ([pixel] == -9999)
        COLOR 0 0 255
    END
    CLASS
        NAME "0 - 5"
        EXPRESSION ([pixel] >= 0 AND ([pixel] <=5)
        #COLOR 200 0 0
         STYLE
         SYMBOL 0
         SIZE 2
         OUTLINECOLOR 200 0 0
         END
    END
    CLASS
        NAME "5 - 10"
        EXPRESSION ([pixel] > 10 AND [pixel] <=20)
        OUTLINECOLOR 243 162 0
    END
    CLASS
        NAME "2 - 50"
        EXPRESSION ([pixel] > 20 AND [pixel] <=50)
        OUTLINECOLOR 0 200 0
    END
   END

But I still get the map with filled contours ...

I know I can use gdal_contour - but I'm just wondering if there is a
way of doing that with MapServer,

Thanks, once again
