[OpenLayers-Users] How to Rotate an image

[Arnd Wippermann]

Hi Josep,

I have forgotten, that you have to apply a context to the stylemap to
display the externalGraphic in map units.
Otherwise has the symbolizer used to display a point feature allways the
same size in every zoom level.

Example:

Regards,
Arnd

Thanks Arnd,

It works! But since I've applied your solution I can't zoom in nor out the
image. Well, in fact it zooms but immediately it returns to the default
display

Here it is: http://jsfiddle.net/gilan/2CK25/
