<div dir="ltr">Hi!<br><br>I'm trying to rotate the symbols around their own center but I canīt; they rotate around another point, In my opinion, the only choice is extend OpenLayers.Renderer.symbol in OpenLayers.Renderer.Elements, to define a element for each angle that I need, from 0 up to 360 degrees.<br>
<br>Another possibility is to create polygons but they change their size with the changes of the zoom of the map and I donīt want this, I need that their size constant.<br><br>Has someone any idea of how I can do this?<br>

<div dir="ltr">Hi!<br><br>This solution is perfect, but I need to rotate the polygons around their own center, since the rotate function doesnīt change their <span><span>inclination</span></span>, it just change their position.<br>
<br>The code is: <br><br> features[4].geometry.rotate(30,new OpenLayers.Geometry.Point(map.maxExtent.left + (4 * slot) + (slot / 2), 0));<br> features[4].layer.drawFeature(features[4]);<br> <br>
features[1].geometry.rotate(30,new OpenLayers.Geometry.Point(5,5));<br> features[1].layer.drawFeature(features[1]);<br><br>where features array comes from the example <a href="http://openlayers.org/dev/examples/graphic-name.html" target="_blank">http://openlayers.org/dev/examples/graphic-name.html</a>.<br>

</div>Sounds like you want this:<br>
<br>
<a href="http://openlayers.org/dev/examples/graphic-name.html" target="_blank">http://openlayers.org/dev/examples/graphic-name.html</a><br>
<br>
There's a set of constants in OpenLayers.Renderer.symbol in<br>
OpenLayers.Renderer.Elements which you could extend.<br>

<br>
</div>The units of the layer have no control over anything. Your units you are<br>
providing are *map* units -- and the *name* you give to those units is<br>
irrelevant. What you want to do is change the size of the units. If you<br>
want to create something that's a different size, you need to provide<br>
the correct size in current map units. (Your map is probably in<br>
degrees.)<br>
