[mapserver-users] WMS and map script

[Murty Maganti]

Tom,

Also, I don't see EXTENT attribute at layer level, from below reference
http://www.mapserver.org/mapfile/layer.html

There is layerObj.setExtent() but the extents are not saved to map file.


Thanks
Murty

That won't help me. 
I add the wms layer dynamically to map using C# mapscript (and then save
the map object to map file).

I can get the extents from capabilities but layer.extent is readonly and
can't be set.

Thanks
Murty

MapServer won't do a GetCapabiilties to get the extent for remote WMS
layers.  If you set LAYER.EXTENT accordingly, layer.getExtent() will
work accordingly.
