If you can, could you please write me the PyQgis script for the other option? all regards, Azzurra 2016-11-16 9:22 GMT+01:00 Marco Grisolia <marco.grisol...@gmail.com>: > If you want to assign a specified buffer for each kind of feature, you > may use a simple PyQGIS script using a call of buffer() from > QgsGeometry().
