[mapserver-users] MapServer 5.2.1 and AGG/PNG - too thick lines in the grid

[Reinoud Bokhorst]

I experienced the same problem a while ago and reverted to using a separate mapfile for the graticule using the GD driver. In your 'main' mapfile you could then create a graticule layer with CONNECTIONTYPE WMS that connects to a URL using the graticule mapfile (f.ex. something like this: http://localhost/cgi/mapserv?map=graticule.map&). This way you still have one entry point for all your layers.

Regards,
Reinoud
