Dear all,
I was confident that it would have been simple, while I can’t find the
proper way od doing that. Having a reference to a QgsVectorLayer, I would
need to use a subset of its features to run an algorithm down the line.
I hoped there was a way to define an input as afeature source with a filter
(QgsFeatureRequest or similar. I’ve tried using
QgsProcessingFeatureSourceDefinition with a selection but with no luck:
pointlayer.selectByRect(rect, QgsVectorLayer.SetSelection)
processing.run("qgis:voronoipolygons", {
'INPUT': QgsProcessingFeatureSourceDefinition(
pointlayer.id(),
True),
'BUFFER': 10,
'OUTPUT': outpath})
error, can’t find the layer with that id, since it expects to find it
in the proje
Any ideas? Is it possible to build a QgsProcessingParameterDefinition
for the task?
Cheers,
Giovanni
