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

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).

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(

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

[Andrea Peri]

Hi ,
I try unsuccesfully to programmatically set the extent of a layer
using mapscript python.

I use this code to set the extent variable:

#... "extent1" is a variable storing the extent I like to set.

print("Add this extent to the layer: %s\n" % (str(extent1)))
clone_map_getlayer_li.extent = extent1
print("The result of add is this: %s\n" %
(str(clone_map_getlayer_li.extent)))


But
The result from printf show that the extent is not update.


>Add this extent to the layer: { 'minx': 424785 , 'miny': 4662585 , 'maxx': 
>696015 , 'maxy': 5057415 }

>The result of add is this: { 'minx': -1 , 'miny': -1 , 'maxx': -1 , 'maxy': -1 
>}

What I'm wrong ?

Many thx for any help.

A.
