[OpenLayers-Users] Dynamic size of point using StyleMap

[Arnd Wippermann]

Hi Yves,

Perhaps that's what you search:

http://openlayers.org/pipermail/users/2008-September/007482.html

var style = new OpenLayers.Style(OpenLayers.Util.applyDefaults({
    pointRadius: "${scaledSize}"
}, OpenLayers.Feature.Vector.style["default"]), {
    context: {
        scaledSize: function(feature) {
            return feature.layer.map.getResolution() *
feature.attributes.size;
        }
    }
});
var styleMap = new OpenLayers.StyleMap({"default": style});

Hi Chris,

Thanks for your answer. May be I wasn't clear on what I want to do or I
don't understand your answer ;) . I wrote a Style object applied to my
vector layer.

I would like that the point radius change for each zoomLevel. i.e. the point
symbol become bigger when zoomLevel is bigger.

Y.
