[mapserver-users] Rendering of Symbols outside map window

[mdprive]

Hi Patrick,

i've submitted a pull request for extending the map by a buffer and then clipping it, so that partial symbols on the edge get rendered as well (wms non tiled mode).

maybe you can build from sources and use this patch to solve your problem.
