Re: getBoundsZoomLevel using bounds is not working

[Sudhindra HS]

Thank you for the suggestion.

But the Google maps performance is very slow while dealing with large amount
of data.

Hence we moved to open layers implementation.

 to delegate to the Maps API correctly.  Out of curiousity, have you
 tried using a separate mapWidget.setZoomLevel(); call?

  Here is my code

  Polygon polygon = new Polygon( points, color, 10, 0.0, color,

  mapWidget.clearOverlays();
  mapWidget.addOverlay( polygon );
 
  mapWidget.setCenter( bounds.getCenter(),mapWidget.getBoundsZoomLevel(
 bounds ));

         mapWidget.clearOverlays();

 mapWidget.setCenter( bounds.getCenter(),mapWidget.getBoundsZoomLevel( bounds 
 ));
