Readme
Takes a line, a start Point, and a stop point and returns a subsection of the line in-between those points. The start & stop points don't need to fall exactly on the line.
This can be useful for extracting only the part of a route between waypoints.
Parameters
point1
Feature<Point> starting pointpoint2
Feature<Point> stopping pointline
(Feature<LineString> | LineString) line to sliceExamples
