locationIndexOnPathTolerance static method
Computes whether (and where) a given point lies on or near a polyline, within a specified tolerance. The polyline is not closed -- the closing segment between the first point and the last point is not included.
point
our needle
poly
our haystack
geodesic
the polyline is composed of great circle segments if geodesic
is true, and of Rhumb segments otherwise
tolerance
tolerance (in meters)
return
-1 if point does not lie on or near the polyline.
0 if point is between poly0
and poly1
(inclusive),
1 if between poly1
and poly2
,
poly.size()-2 if between polypoly.size() - 2
and polypoly.size() - 1
Implementation
static int locationIndexOnPathTolerance(
Point point, List<Point> poly, bool geodesic, num tolerance) =>
locationIndexOnEdgeOrPath(point, poly, false, geodesic, tolerance);
