[OpenLayers-Users] Not change the size o polygons with zoom change

[Jose A. C.]

Hi!

This solution is perfect, but I need to rotate the polygons around their own
center, since the rotate function doesn´t change their inclination, it just
change their position.

The code is:

            features[4].geometry.rotate(30,new
OpenLayers.Geometry.Point(map.maxExtent.left + (4 * slot) + (slot / 2), 0));
            features[4].layer.drawFeature(features[4]);

            features[1].geometry.rotate(30,new
OpenLayers.Geometry.Point(5,5));
            features[1].layer.drawFeature(features[1]);

where features array comes from the example
http://openlayers.org/dev/examples/graphic-name.html.

Thanks!!!
