Hi,<div><br></div><div>If you are saving the line in a vector layer then as I said earlier.. your feature`s geometry type should not be a line but geometry collection which should contain not only line segment but also point geometry which will be drawn as a rotated triangle.</div>

<div>Hi Hua Jie,<br>
<br>
You could try to define your own arrow symbol. There's one
defined [here], see line 1 :<br>
OpenLayers.Renderer.symbol.arrow = [0,2, 1,0, 2,2, 1,0, 0,2]<br>
<br>
I haven't tried it, but it could do the trick.<br>
