[mapserver-users] How set the extent programmmatically using python mapscript

[Emanuele Di Giacomo]

Hi,
it seems to me that the traceback is saying that you are passing wrong
arguments to setExtent.

Please read carefully the documentation
(http://mapserver.org/mapscript/mapscript.html#layerobj): setExtent
takes 4 parameter (minx, miny, maxx and maxy of the extent) and not
the extent (a rectObj).
