fitBounds set the zoom 1 step behind

[Dones]

Hi guys, i've a problem with fitBounds function.

1)In the first page i get the bounds of the map with getBounds
function.

2) I send these bounds as parameters to another page.

3) with fitBounds(bounds) function in the new page, i'd like to set
the best zoom of the map to get the same map as the previous page.

bounds=new google.maps.LatLngBounds(SWlatLng, NElatLng);
map.fitBounds(bounds);

Unluckily the zoom of the map is one step smaller than the previous
map, and if i repeat this action next times, the zoom get "out" again
and again...

Can u help me?

Not really. We need to see what you see, and by far the best way to do
that is provide a link to your map..

Where i'm getting wrong?

Thanks

Ah I see now!

What I think is happening, is 'fitBounds' tries to find a zoom level
that allows the whole of the 'bounds' to be visible. Because the map
has a logo and nav buttons etc, the whole map area would not permit
the required area to be totally visible.

If for example you where using fitBounds to layout a groundoverlay, or
even a bunch of markers, you probably dont some of them hidden behind
the chrome of the map.


Course dont know what you actully trying to do*, but could you perhaps
send the zoom level though?

Or if you know its always going to be used in this way you could
reasonably safely just zoom in a step?

Or could maybe try using disableDefaultUI and only enable controls
after the fitBounds - but probably the logo will still get in the
way...


* another reason a link to your actual map rather than just a demo is
sometimes useful too.

Good catch. I tried it with

map.fitBounds(map.getBounds());

And it zooms out one level. It really seems that there are some
paddings in fitBounds() calculation.

Oh understood...

Yes i think i can do what i want passing the coordinates of the center
and the zoom, and in the second map center it with setCenter and zoom
it with setZoom.

Well i just want to have in the second map the same location and zoom
of the previous one...

I don't know why i get an error in the second page, but u can see the
code...i think it could work now...

Ok passing the coordinates of center and the zoom it works great. The
problem now is when u have to set the map after a geocode request..

If u search a city for example, the Geocode Response Object returns
this:
{types[]: String,
formatted_address: String,
address_components[]: {
short_name: String,
long_name: String,
types[]: String
},
geometry: {
location: LatLng,
location_type: GeocoderLocationType,
viewport: LatLngBounds,
bounds: LatLngBounds?
}

}

...so i haven't the zoom to have the best view of the city (or street)
but just the bounds...

So the only way i can see is to use fitBounds function...

is it clear? Maybe i'm going to post another example...
