Hi OpenLayers developers, as some of you may have already heard, I've implemented a first version of the OpenLayers.Layer.Map24 class to add support for the Map24 provider.
Check it out, here's a demonstration page: http://dev.openlayers.org/sandbox/thliese/openlayers/examples/map24.html Of course, it's just a first "beta version" and there may still be some bugs or issues that need to be fixed. I'm also not an OpenLayers expert (there are probably some test cases that I am not aware of) so I would really appreciate your feedback :) The source is available in my sandbox at http://svn.openlayers.org/sandbox/thliese/openlayers/lib/OpenLayers/Layer/Map24.js Using the new class is - similar to the google layer - as simple as this: Include the scripts: <script type="text/javascript" src="http://api.maptp.map24.com/ajax?appkey=YOURKEY";></script> <script type="text/javascript" src="../lib/OpenLayers.js"></script> Create the Map24 layer: var map = new OpenLayers.Map("mapDiv"); var map24Layer = new OpenLayers.Layer.Map24("Map24"); map.addLayer(map24Layer); Please see http://svn.openlayers.org/sandbox/thliese/openlayers/examples/map24.html for additional usage information). Some notes about the implementation: * Since the initialization of the Map24 map is asynchronous (callback), the loadMapObject function simply sets a placeholder value for the this.mapObject field. Is there a better way to handle an asynchronous initialization using the OpenLayers API? * There is no reliable way (at least I haven't found one) to tell the Map24 API to display a map with a certain resolution or to display a specific rectangle of geo coordinates. The only reliable information information about the current map is obtained through an asynchronous callback function called mapViewChanged, which calls this.map.setCenter to manually redraw the other layers. Because the painting of the Map24 happens asynchronously, panning also looks a bit weird because the painting of the map is a bit "behind" the other layers - any ideas as to how to get rid of this effect? * I'm not really satisfied with the results when using a zoom box. Did I implement the getZoomForExtent function correctly? Thanks to you all for this great API - I'm looking forward to your comments & suggestions, greetings from Darmstadt, Germany, Thorsten Liese -- componio GmbH Robert-Bosch-Straße 7 D - 64293 Darmstadt Tel: +49.6151.500.367.12 Office: +49.6151.500.367.0 Fax: +49.6151.500.367.6 Internet: http://www.componio.net E-Mail: [EMAIL PROTECTED] HRB 9624 - Registergericht Amtsgericht Darmstadt _______________________________________________ Dev mailing list [email protected] http://openlayers.org/mailman/listinfo/dev
