Allow tolerance in intersects tests #25482

Author Name: gcarrillo - (gcarrillo -) Original Redmine Issue: 17585

Redmine category:geometry

>>> my_line = QgsGeometry().fromWkt('0 0, 963461.42999999970197678 1077875.79199999943375587, 1 1')
>>> my_point = QgsGeometry().fromWkt("Point (963461.430 1077875.792)")
>>> my_line.intersects(my_point)
False

Any way to set a tolerance or something so that such intersection is found? The line was created digitizing it in QGIS using snapping (vertex mode, 9 pixels of tolerance).

Same behavior in 2.x. I'm changing this from a bug to a feature request, because the current behaviour is correct - those two geometries don't intersect.

subject was changed from Polyline.intersects(Point) doesn't work in QGIS master to Allow tolerance in intersects tests
tracker_id was changed from 1 to 2

It would be nice to have a tolerance parameter so that this very little discrepancies can also be found, but I guess one could snap one geometry to the other (with such little distance as tolerance) and then run intersects.
