OpenLayers 2 had a very useful map.zoomToExtent( extent ) feature. Is there something similar in OpenLayers 3? I can get the extent of interest with source.getExtent(), but I can’t figure out how to apply that extent as a zoom level.
var zoomToExtentControl = new ol .control.ZoomToExtent({ extent : [-11243808.051695308, 4406397.202710291,-4561377.290892059,6852382.107835932]}); it works when I clicked on it but when I try to replace the coordinates by geofield.geometry.getBounds() the map doesn’t display.
I’ve just started having a look at OpenLayers 3 and am attempting to zoom to a single feature whose extent is to be a geoJSON object sent by the server (which will change at each refresh, so I can’t hard code the zoom /central point). I would like this to happen preferably as soon as the page loads, but I’m struggling to get it to work.
Right now, I store all active features in a separate array and calculate the extent from there. var coordinates = features.map(function(feature) {return feature.getGeometry().getCoordinates();}); var extent = ol . extent .boundingExtent(coordinates); – SomeBdyElse Dec 28 ’13 at 20:23, This map has a view that is constrained in an extent . This is done using the extent view option. Please note that specifying constrainOnlyCenter: true would only apply the extent restriction to the view center.
