This code, as it's written, would NEVER have worked. Maybe you use an
AI at some stage to fix something and it broke the code?
Try:
for feat in point_layer.getFeatures():
geom = feat.geometry()
if point_crs != project_crs:
# no need to clone!
geom.transform(transform_point_to_project)
if surface_geom.intersects(geom):
new_feat = QgsFeature(feat)
new_feat.setGeometry(geom)
provider.addFeatures([new_feat])
result['features'].append(new_feat)
result['count'] += 1
Or:
request = QgsFeatureRequest()
request.setDestinationCrs(project_crs,
QgsProject.instance().transformContext())
for feat in point_layer.getFeatures(request):
geom = feat.geometry()
# no need to transform, it's now done for us!
if surface_geom.intersects(geom):
new_feat = QgsFeature(feat)
new_feat.setGeometry(geom)
provider.addFeatures([new_feat])
result['features'].append(new_feat)
result['count'] += 1
