[OpenLayers-Users] zoom according to feature's sizes

[Gery .]

Hello folks,

Yesterday I got a nice trick from Arnd about zooming all features (points/polylines/polygons). Now I would like to ask about zooming features according to their sizes. Imagine this case, I have a point and a big polygon that I want to zoom in (also center in the map), the point is too smaill so I need to set a specific zoom level for this, this works well for the point case inside my variable "myfeatures":

var myfeatures = feature.geometry.bounds;
map.setCenter(myfeatures.getCenterLonLat(),10);

where 10 is the zoom level. However, this doesn't work when the stored feature is a big polygon for instance. I was thinking about a simple if/else to do this, but how can I differentiate between points, polylines and polygons? a couple of things I tried:

map.zoomToExtent(myfeatures);
map.zoomToScale(216672);

but this is kind of a static zooming, so it fails when the feature is too big and goes beyond this zoom of 216672.

Any idea is much appreciated,

Best regards,

Gery
