[Qgis-user] Error in clipping a raster

Thu Mar 23 05:45:31 PDT 2017

Hello forum

I'm trying to cut a raster (geo tif) using a polygon shape. Both are in the
same reference system. The polygon is not a regular polygon, but has many
vertex.
I'm using raster > extraction > clipper, but at the end I receive this
error message
ERROR 1: Unable to compute a transformation between pixel/line and
georeferenced coordinates for /home/giacomo/Desktop/RSM/bordi.tif.
There is no affine transformation and no GCPs.

Thank you
