[mapserver-users] Is mapserver possible to dynamic layout

[Tamas Szekeres]

I thought you have a the color value itself as the attribute.
But if you'd categorize by a different value you might want to define a
different class for each value, something like

LAYER
  CLASS
    EXPRESSION ([MYCOLORATTRIBUTE]=1)
    STYLE
       COLOR 255 255 0
    END
  END
  CLASS
    EXPRESSION ([MYCOLORATTRIBUTE]=2)
    STYLE
       COLOR 255 0 0
    END
  END
END


Best regards,

Tamas
