get_tangent

Gets the tangent of the path at the point.

Note that certain points on a path may not have a single tangent, such as sharp turns. At such points, there are two tangents -- the direction of the path going into the point, and the direction coming out of it. The direction argument lets you choose which one to get.

If the path is just a single point (e.g. a circle with radius zero), then tangent is set to `0, 0`.

If you want to orient something in the direction of the path, [method@Gsk.PathPoint.get_rotation] may be more convenient to use.

Parameters:

this	a `GskPathPoint`
path	the path that this is on
direction	the direction for which to return the tangent
tangent	Return location for the tangent at the point
