Google地图在给定窗口中选择缩放以适合国家/地区 [英] Google Maps choose zoom to fit country TIGHTLY in given window

问题描述

我刚开始使用Google Maps API。我成功地创建了一个以给定国家为中心的地图。

I am just starting out with the Google Maps API. I have successfully managed to create a map centered on a given country

function create_map (geometry) {
    var mapOptions = {
        center: geometry.position,
        zoom: 6 // unimportant, see fitBounds
    };
    var map = new google.maps.Map (
        document .getElementById ("map-canvas"),
        mapOptions);

    map.fitBounds (geometry.viewport);
}

function initialize ()
{
    new google.maps.Geocoder().geocode (
        {'address': 'france'},
        function (results, status)
    {
        if (google.maps.GeocoderStatus.OK == status)
            create_map (results [0].geometry);
        else
            alert ("bad: "+ status);
    });
}

google.maps.event.addDomListener (window, 'load', initialize);

这种方式可行，但缩放级别选择空间很大。我希望地图尽可能大，没有舒适的边缘。我怎样才能使API紧密贴合窗口？

This works but the zoom level is chosen with lots of room to spare. I want the map to be as big as possible, with no "comfortable" margin. How can I make the API fit the map tightly to the window?

推荐答案

这是不可能的。缩放地图可能只能设置为整数值，但是您要实现的要求是浮点值。

It's not possible. The zoom of a map may only be set to integer-values, but what you're trying to achieve would require a float-value.

蓝色矩形标记视口，当您增加放大1蓝色矩形将不适合容器。

The blue rectangle marks the viewport, when you increase the zoom by 1 the blue rectangle will not fit into the container.
