[Mapserver-users] How to center labels in land parcels displayed by line layers?

[Frieso ter Haseborg]

Hi,

>Why not change the layer type to polygon?
This had no results on my first tries and I must have lost track somehow. But shame on me, you're absolutely right, it works great with 'TPYE POLYGON' and - that's the 2nd part of the key - 'POSITION CC'. I left POSITION on AUTO which returns the labels back to the middle of the line as mentioned in the docs.

So for the record, for those who run into the same - here comes the right layer definition:
LAYER
   TYPE POLYGON        # <= !!!
   ...
   CLASS
      ...
      LABEL
      ...
         POSITION CC   # <= !!!
      END
   END
END

>the attached ms.gif was empty?
Actually the gif wasn't an GIF at all (wrong format => PSP), I reposted it a 2nd time half'n hour ago.

Thanx a lot!
Frieso
