[mapserver-users] LABEL POSITION - Numeric or String from a database

[tommaso]

Hallo Donald,

you can define a layer with so many classes how are your possible label
positions and filter each class with the value of the attribute
"AnchorPositionTxt"

i.e:

LAYER

  NAME "layer"
  ...
  ...
  CLASSITEM "AnchorPositionTxt"
  LABELITEM "name"
  CLASS
    EXPRESSION "ul"
    LABEL
        POSITION ul
        ...
    END
  END
  CLASS
    EXPRESSION "lr"
    LABEL
        POSITION lr
        ...
    END
  END
END

Cheers,
Tommaso
