[mapserver-users] Road shields on Mapserver 7

[Stephen Woodbridge]

Don't use the geotransform labelpnt, in fact don't label it:

   symbol
     name "arrow-north"
     type truetype
     font arrows
     character ""
     filled true
   end
   LABEL
     ...
     CLASS
       STYLE
         COLOR "#444488"
         SIZE 8
       END
     END
     CLASS
       STYLE
         SYMBOL "arrow-north"
         GAP -60
         ANGLE -90
         COLOR "#555555"
         SIZE 8
       END
     END
   END
