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

[Emanuele Di Giacomo]

Hi Andrea,
you could try using the setExtent/getExtent methods:

    clone_map_getlayer_li.setExtent(extent1.minx, extent1.miny,
extent1.maxx, extent1.maxy)
    print("The result of add is this: %s\n" %
(str(clone_map_getlayer_li.getExtent())))
