PointTrackWithArrows

Create an OpenLayers PointTrack with direction (arrows).

Usage

        var l = new OpenLayers.Layer.PointTrack( "PointTrack", {
          styleMap : new OpenLayers.Style({
              graphicName : "track",
              strokeColor : "red",
              fillColor : "red",
              pointRadius : 2,
              fillOpacity : 0.5,
              strokeWidth : 2,
              graphicName: "arrow",
              rotation : "${angle}"
          });
        });

Background

I’ve merged OpenLayer’s PointTrack code from these sources (thank you for all the hard work!):
