将图像添加到openlayers地图

Question

这是我在openlayers地图上添加图像的代码。

var image = new OpenLayers.Layer.Image(
    'Image 1',
    'http://belocalat.com/wp-content/plugins/openlayers/data/baselayer-img1.png',
    //new OpenLayers.Bounds(27.418100,35.771100,28.388000,36.558500),
    new OpenLayers.Size(800,255),
    {isBaseLayer: false}
 );

map.addLayer(image);

但是，我无法在openlayers上显示图像。有人可以给我解决方案吗？

提前致谢。

Answer 1

我尝试过以下代码并且它有效。从小提琴中签出。不要忘记从图层切换器中选择图像图层。

var osm = new OpenLayers.Layer.OSM();

var graphic = new OpenLayers.Layer.Image(
    'Image',
    'http://belocalat.com/wp-content/plugins/openlayers/data/baselayer-img1.png',
    new OpenLayers.Bounds(27.418100,35.771100,28.388000,36.558500),
    new OpenLayers.Size(800,255),
    {numZoomLevels: 3}
);

map.addControl(new OpenLayers.Control.LayerSwitcher());
map.addLayers([osm, graphic]);
map.zoomToExtent(new OpenLayers.Bounds(27.418100,35.771100,28.388000,36.558500));

我希望它能帮助你...
