antialiasing line features..

[Ivan Price]

hi there..

is there a way to antialias line features ? antialiasing is working for
labels fine but the following has no effect for the line itself:

  SYMBOL
    NAME 'line'
    TYPE ELLIPSE
    FILLED TRUE
    POINTS 1 1 END
    ANTIALIAS TRUE
  END

..

  CLASS
    EXPRESSION "NATIONAL HIGHWAY"
    STYLE
      ANTIALIAS TRUE
    END
    LABEL
      FONT arial
      TYPE truetype
      ANTIALIAS on
      COLOR 0 0 0
      ANGLE AUTO
      SIZE 9
    END
    SYMBOL "line"
    SIZE 3
    COLOR 204 0 51
  END

running the following (on win2k)
C:\mapserver>mapserv -v
MapServer version 4.6.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=PDF
OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=THREADS INPUT=POSTGIS
INPUT=ORACLESPATIAL INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG


any ideas ?

cheers,
