Transparent polygons

[Banister Trevor]

Polygon shapes can be treated as lines or even points. The documentation has
a nice section on this technique.

Hi everyone,

Trying to display a polygon shape layer over another one. I would like
to see the underlying layer through those polygons. I could tranform the
layer into lines but on another hand I need those polygons in the CGI.
What should I put in the map file ?

Thanks,

Marc
