the previous versions of mapserver (incorrectly I think) used the value of the label buffer to expand the background billboard. You'd get nice results whith a 1 or 2 px buffer like in your case, but unusable ones when you added larger buffers.
I hope we can work around this for 5.6 with the possible label style rewrite. regards, thomas www.camptocamp.com +33 4 79 26 57 97 On Tue, Jul 14, 2009 at 03:01, Steve Lime<[email protected]> wrote: > Wonder if it's the same issue as with the polygon size you noted.
