Thanks for your reply. I'm aware that the map has zoom levels and no continuous zoom and you are right, that I can not expect it to 'accept' all of my bounds that I specify. But what I find strange is, that the call map.fitBounds( map.getBounds()) changes the bounds. In my opinion the fit bounds method wouldn't have to do anything. I also disabled the UI with "disableDefaultUI: true" in MapOptions, because the documentation of the other possible method Map.panToBounds() says: "The bounds will be positioned inside the area bounded by the map type and navigation controls, if they are present on the map.". Further investigations show that even if I shrink the bounds before applying them to the map with fitBounds() the map will move south: Instead of a simple map.fitBounds( map.getBounds()) I'm doing a shrinking of the bounds before reapplying them: var bounds = map.getBounds(); var ne = bounds.getNorthEast(); var sw = bounds.getSouthWest(); var k = 5.0; var n = ne.lat() - k; var e = ne.lng() - k; var s = sw.lat() + k; var w = sw.lng() + k; var neNew = new google.maps.LatLng( n, e ); var swNew = new google.maps.LatLng( s, w ); var boundsNew = new google.maps.LatLngBounds( swNew, neNew ); qlog( "bo=" + bounds.toUrlValue() ); qlog( "bn=" + boundsNew.toUrlValue() ); map.fitBounds( boundsNew ); If I look at the log I get: log:bounds are: 34.931422,28.897984,57.63981,49.772008 log:bo=34.931422,28.897984,57.63981,49.772008 log:bn=39.931422,33.897984,52.63981,44.772008 log:bounds_changed_listerner: 33.916404,28.897984,56.975181,49.772008 log:bo=33.916404,28.897984,56.975181,49.772008 log:bn=38.916404,33.897984,51.975181,44.772008 log:bounds_changed_listerner: 32.914338,28.897984,56.315118,49.772008 log:bo=32.914338,28.897984,56.315118,49.772008 log:bn=37.914338,33.897984,51.315118,44.772008 log:bounds_changed_listerner: 31.92558,28.897984,55.659918,49.772008 log:bo=31.92558,28.897984,55.659918,49.772008 log:bn=36.92558,33.897984,50.659918,44.772008 log:bounds_changed_listerner: 30.950443,28.897984,55.00986,49.772008 log:bo=30.950443,28.897984,55.00986,49.772008 log:bn=35.950443,33.897984,50.00986,44.772008 log:bounds_changed_listerner: 29.989199,28.897984,54.3652,49.772008 log:bo=29.989199,28.897984,54.3652,49.772008 log:bn=34.989199,33.897984,49.3652,44.772008 log:bounds_changed_listerner: 29.042078,28.897984,53.72618,49.772008 log:bo=29.042078,28.897984,53.72618,49.772008 log:bn=34.042078,33.897984,48.72618,44.772008 log:bounds_changed_listerner: 28.109274,28.897984,53.09302,49.772008 log:bo=28.109274,28.897984,53.09302,49.772008 log:bn=33.109274,33.897984,48.09302,44.772008 log:bounds_changed_listerner: 27.190946,28.897984,52.465925,49.772008 log:bo=27.190946,28.897984,52.465925,49.772008 log:bn=32.190946,33.897984,47.465925,44.772008 log:bounds_changed_listerner: 26.287218,28.897984,51.845083,49.772008 As you can see, the east and west coordinates stay the same, but the north and south coordinates move slowly south. I guess, there's not a lot that one can do... but if anyone has another idea? :-) Best regards, Klaas. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
