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?
Thank you,
Marian
