Hi, I have tried to run clipping processing algorithm and it fails. First version: srs = qgis.core.QgsCoordinateReferenceSystem(4019, qgis.core. QgsCoordinateReferenceSystem.EpsgCrsId)
#Input Layer inputLayer = qgis.core.QgsVectorLayer(shapeFileLocation + “/inputLineString.shp”, “inputLineString”, “ogr”) inputLayer.setCrs(srs) Clipping Layer: clipLayer = qgis.core.QgsVectorLayer(“Polygon?crs={0}”.format(srs.authid()) #algorithm to add a clipping polygon feature #the algorithm works because I tested with clipLayer.getFeatures() and I was able to extract the geometry and points ….. …. #calling processing algorithm. processing.runalg(‘qgis.clip’, inputLayer, clipLayer, “output.shp”) The error: Unable to execute algorithm Wrong parameter value: Polygon?crs=ESPG:4019 Any idea why is not working?
