[Qgis-user] Number of vertices

[Martin Bain]

Hi Anke,
The asPolyline() function of a geometry returns a list of points.  You can then simply get the length of the list:


lyr=iface.activeLayer()
sel=lyr.selectedFeatures()
obj=sel[0].geometry()
verts=obj.asPolyline()
print verts
[(526002,6.81305e+06), (526011,6.81309e+06), (526016,6.81311e+06)]

print len(verts)
3

Cheers,
Martin.
