inline

Computes the point that exists at a given distance along the path geometry along with the index of the segment the point is on and the directional vector at that point.

Parameters

length	The distance to walk along the path.
startSegment	The index of the segment at which to begin walking. Note: This index is global to the entire path, not just a particular figure.
worldTransform	The transform to apply to the path prior to walking.
flatteningTolerance	The flattening tolerance to use when walking along an arc or Bezier segment. The flattening tolerance is the maximum error allowed when constructing a polygonal approximation of the geometry. No point in the polygonal representation will diverge from the original geometry by more than the flattening tolerance. Smaller values produce more accurate results but cause slower execution.
pointDescription	When this method returns, contains a description of the point that can be found at the given location.
