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

[Michael Schulz]

Hi,

automatic positioning of labels centered in a polygon works with mapserver for layers of type 
polygon only. Mapserver won't position a line label centered in pseudo-polygon (other than by 
chance). Why not change the layer type to polygon?

Actually, mapserver will by default label every line segment (cit. from docs: "Lines are labeled at 
the middle of the longest arc in the visible portion of the line"), but by providing the MINDISTANCE 
parameter, you can control the behaviour of duplicate labels.

BTW, is mapserver not drawing anything? Since the attached ms.gif was empty?

Cheers, Michael
