Hi all,
i have a question for you. I'd like to have a new function in my plugin that
makes an autime snapping if a start point or end point of a new feature
inserted is closed to a vertex or segment base on a values setted ina
configuration file.
>From plugin console:
l = iface.activeLayer() --activeLayer
f = l.selectedFeatures()[0] -- new fetaure inserted
start = f.geometry().asPolyline()[0] -- get the start point (the point that i
would like to snap to a segment)
result = l.snapWithContext(start,10,QgsSnapper.SnapToVertexAndSegment) -- i use
result
(0, {0.0: [<qgis._core.QgsSnappingResult object at 0x0000000018B9C400>],
0.09699529788394015: [<qgis._core.QgsSnappingResult object at
0x0000000018B9C620>]})
I notice that the key 0.09699529788394015 is the effective distance between my
start point and the segment.
My question is:
How can i modify the feature geometry to snap to the segment according to
result?
Thanks
Francesco
