Question

我创建了一个简单的html来测试我制作的一些地图图块。问题是我让他们使用TMS投影，但我使用了一个OSM示例，所以我的所有图块都是颠倒显示的。我尝试切换到TMS，但经过几十次尝试失败后，我似乎错过了一些东西，有人可以帮忙修复代码吗？

        var map, layer;

        //Initialise the 'map' object
        function init() {

            map = new OpenLayers.Map ("map", {
                controls:[
                    new OpenLayers.Control.Navigation(),
                    new OpenLayers.Control.PanZoomBar(),
                    new OpenLayers.Control.Permalink(),
                    new OpenLayers.Control.ScaleLine({geodesic: true}),
                    new OpenLayers.Control.Permalink('permalink'),
                    new OpenLayers.Control.MousePosition(),                    
                    new OpenLayers.Control.Attribution()],
                maxExtent: new OpenLayers.Bounds( 0.0, -10000.0, 10000.0, 0.0),
                maxResolution: 64.000000,
                numZoomLevels: 7,
                units: 'm',
                projection: new OpenLayers.Projection("EPSG:900913"),
                displayProjection: new OpenLayers.Projection("EPSG:4326")
            } );

            // Add Base map.
            layer = new OpenLayers.Layer.OSM("Base Map", "tiles/base/${z}/${x}/${y}.jpg", {numZoomLevels: 7, alpha: false, isBaseLayer: true});
            map.addLayer(layer);

            // Add Layers.
            layer = new OpenLayers.Layer.OSM("Terrain", "tiles/terrain/${z}/${x}/${y}.png", {numZoomLevels: 7, alpha: false, isBaseLayer: false});
            map.addLayer(layer);
            layer = new OpenLayers.Layer.OSM("Lables", "tiles/lables/${z}/${x}/${y}.png", {numZoomLevels: 7, alpha: false, isBaseLayer: false});
            map.addLayer(layer);

            var switcherControl = new OpenLayers.Control.LayerSwitcher();
            map.addControl(switcherControl);
            switcherControl.maximizeControl();

            if( ! map.getCenter() ){
                var lonLat = new OpenLayers.LonLat(10, 10).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());
                map.setCenter (lonLat, 5);
            }
        }

    </script>
</head>
    <body onload="init();">
    <div style="width:100%; height:100%" id="map"></div>
</body>

</html>

基本上我需要的是一个基本地图图层（jpg）和几个可选图层（png具有透明度）全部使用TMS，256x256,7个缩放级别并位于'tiles / layername /...'

不确定，但这可能有所帮助：

OpenLayers如何从OSM更改为TMS？
