سؤال

I was wondering, has smooth zooming and panning described in http://www.win.tue.nl/~vanwijk/zoompan.pdf been implemented in OpenLayers?

It has been implemented for PolyMaps: http://bl.ocks.org/RandomEtc/600144 And ModestMaps: https://github.com/stamen/modestmaps-js/tree/master/examples/zoompan

هل كانت مفيدة؟

المحلول

Since 3.20.0, OpenLayers has an ol.View.animate() method that allows smooth zooming and/or panning (among others) and deprecates the old ol.animation.

From the latest API docs:

The view's center, zoom (or resolution), and rotation can be animated for smooth transitions between view states.

So, you can zoom and pan by doing:

var view = map.getView();
view.animate({
    center: coordinates,
    zoom:   zoomLevel
});
