antialias lines

[Rodrigo Martín LÓPEZ GREGORIO]

Hi Bailey.

To give width to a cartoline symbol you need to use the SIZE property of
STYLE element instead of WIDTH.

IMAGETYPE png24

OUTPUTFORMAT
         NAME png24
         DRIVER "GD/PNG"
         MIMETYPE "image/png"
         IMAGEMODE RGB
         EXTENSION "png"
END

SYMBOL
         NAME 'cartoline'
         TYPE cartoline
         LINECAP round
         LINEJOIN round
         LINEJOINMAXSIZE 3
END



LAYER
        NAME "Contours"
        STATUS on
        TYPE LINE
        DATA "Contours"
        SYMBOLSCALE 24000
        TRANSPARENCY alpha
        CLASS
                 STYLE
                          COLOR 000 000 000
                          SYMBOL "cartoline"
                          ANTIALIAS TRUE
                          SIZE 3
                  END
        END
END

Rodrigo.
