Shortens a line segment and returns the line points of the shortened segment.
|
| ShortenPartialPolylineByDistanceFromStartAndEnd |
Shortens a partial polyline, given by the first point at index startIndex and the last index endIndex, at both sides in such a way that the new start has a distance distanceFromStart to the original start of the polyline, and the
new end has a distance distanceFromEnd to the original end of the polyline. If the shortening leads to a polyline of zero length, then null is returned.
