Hope I got my point through.. regards, Imran On Wed, Jan 23, 2013 at 7:11 PM, 杨华杰 <[email protected]> wrote: Hi Alexandre Thank you, I will try this.

There's one defined [here], see line 1 : OpenLayers.Renderer.symbol.arrow = [0,2, 1,0, 2,2, 1,0, 0,2] I haven't tried it, but it could do the trick.
