How to rotate a feature in openLayers

Question

I have an svg image and I want to rotate it around itself so I do the following:

var origin = new OpenLayers.Geometry.Point(vertices[0].x,vertices[0].y);            
feature.geometry.rotate(90 ,origin);
feature.layer.drawFeature(feature);

but nothing happens. Does anyone know why?

Thanks in advance.

Answer 1

I think you need to use :

layer.addFeatures(features)

Check this example : http://openlayers.org/dev/examples/styles-rotation.html

Answer 2

dont try it with point, you cant understand your obj. rotate or not...this code is for linestring and works good.

var line = new OpenLayers.Feature.Vector(
                new OpenLayers.Geometry.LineString(points),null,null);
vector.addFeatures([line]);

var origin = new OpenLayers.Geometry.Point(10, 10);

line.geometry.rotate(30, origin);
line.layer.drawFeature(line);

i hope it helps you...
