AW: [OpenLayers-Users] drawing an ellipse

[Arnd Wippermann]

Hi,

perhaps the use of an externalGraphic will do the job. 

Change the select style in graphic-name.js of the OpenLayers example to see
the effect:

"select": {
    pointRadius: 20,
    externalGraphic:"img/check-round-green.png",
    graphicWidth:30,
    graphicHeight:20,
    fillOpacity: 1,
    rotation: 20
}

If you use a context you can change the width, height and rotation due to
some attributes of your features.

Arnd

I am actually looking at Renderer.SVG
[http://dev.openlayers.org/docs/files/OpenLayers/Renderer/SVG-js.html] and
Renderer.SVG2
[http://dev.openlayers.org/docs/files/OpenLayers/Renderer/SVG2-js.html] and
wondering if there is a chance with those. I am not familiar with the
innards of OL, so am not sure how a renderer relates to a layer. I don't see
any examples with SVG... did I overlook them?

(ir)regular polygons (an ellipse is just an irregular polygon with many
sides). But you could use the same technique for programmatic ellipse
generation.
