[OpenLayers-Users] Circles

[Arnd Wippermann]

This is some code to create a regular polygon:

//Openlayers.Geometry.Point
var origin = {};
origin.x = map.getCenter().lon;
origin.y = map.getCenter().lat;

//create Regular Polygon Geometry
//OpenLayers.Geometry.Polygon.createRegularPolygon = function(origin,
radius, sides, rotation)
var objF = OpenLayers.Geometry.Polygon.createRegularPolygon(origin,
map.getExtent().getHeight()/20, 6, 90);

//create vector layer
var vlayer = new OpenLayers.Layer.Vector("Editable Vectors");
map.addLayer(vlayer);
//or use a existing vector layer
//var vlayer = map.layers[i]; //i - index of vector layer

//create feature
var theFeature = new OpenLayers.Feature.Vector(objF,null,null);

//add feature
vlayer.addFeatures(theFeature);

Hi Mika, Christopher, 

I have been trying to do this for a while now and still haven’t figured it
out, 

Mika, would it be possible for you to show us an example? 

Thanks 

Kenny

Hi, 

I've been using regular polygon for that (with like 40 sides). I don't 

know if there's another way.
