MapServer LAYER>CLASS>STYLE Object

MapServer allows you to define styles for features. These can be stacked on top of each other. Common simple style settings are:

POINT (SYMBOL)

STYLE
    SYMBOL "circle"
    SIZE 8
    COLOR 0 128 0
END

POLYGON

STYLE # solid fill
	COLOR 115 192 0
END

STYLE # thick outline (could use a circle symbol with size too)
    OUTLINECOLOR 0 0 0
    WIDTH 2
    ANTIALIAS TRUE
END

POLYLINE

NAME "Streets"
   STYLE
      COLOR 192 192 192
      SYMBOL 'continue' 
      SIZE 4
      ANTIALIAS TRUE
   END
   STYLE
      COLOR 255 255 255 
      SYMBOL 'continue' 
      SIZE 2
      ANTIALIAS TRUE
   END

ANNOTATION

CLASS
      LABEL
         FONT "arialbd"
         TYPE TRUETYPE
         COLOR 0 0 0
         OUTLINECOLOR 255 255 255
         SIZE 10
         POSITION cc
         ANTIALIAS TRUE
      END
END

If the symbol that you wish to use is quite large it is advisable to offset it in order for the “PointInfo” search to return the correct results. Normally the symbol will be placed with the top left hand corner at the coordinates of the point. If a user then clicks on the centre of the actual symbol this may not fall within the “PointInfo” tolerance (defined in the webconfig - <add key="MapPixelTolerance" value="10"/>) and incorrect or no results may be returned.

SYMBOL OFFSET

CLASS
      STYLE
         SYMBOL "speedcamera"
            OFFSET -5 -5
      END
