Openlayers谷歌地图getTileBounds

Question

如何在openlayers中指定一个点，并使用google map v3作为基层来获取瓦片的边界。我不能链接(kaMap:second getTileBounds)，我不能getTileSize(GoogleMap)。

http://dev.openlayers.org/releases/OpenLayers-2.11/doc/apidocs/files/OpenLayers/Layer/KaMap-js.html

我的代码示例：

 getTileInformationForPoint : function(point) {
    var layer = this.map.baseLayer;

    //Get the bounds of the tile that encases point
    var lonLat = new OpenLayers.LonLat(point.getLongitude(), point.getLatitude());
    lonLat = lonLat.transform('EPSG:4326','EPSG:3857');
    var viewPortPixel = this.map.getViewPortPxFromLonLat(lonLat);
    var tileBounds = layer.getTileBounds(viewPortPixel);

Answer 1

OpenLayers.Layer.Grid.getTileBounds()看起来像是在整个瓦片网格上返回一个边界--所有当前加载的瓦片。这看起来不像你需要的。

您是否尝试过在传入经度/纬度位置后返回OpenLayers.Tile对象的OpenLayers.Layer.Grid.getTileData()？然后，可以对Tile对象调用getBoundsFromBaseLayer()。
