[Qgis-user] Help cutter raster

[Germán Carrillo]

Make sure that the mask layer has polygons (features) in it, or if you are
editing, make sure that you've saved the polygons you drew.

(Asegúrate que la capa que usas como máscara tenga polígonos, o si estás
editandola, asegúrate que has guardado los polígonos que dibujaste).

Regards,

Germán
