Is there a way to add an arrow to a path element so that I can display a directed line on the map.
Hello,
PathElement has StrokeStartLineCap and StrokeEndLineCap that can be set to Triangle (similar to an arrow), but for this to be visible, the line has to be thicker, because the triangle starts from the edges of the line, does not project out on the sides. Adding an arrow to PathElement is currently not possible; probably a new feature; I can submit it on your behalf. Let me know if you'd like me to do so.
Thank you,
Sam
