Question

以下是我在openlayers地图上添加图片的代码。

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。谁能给我解决这个问题？

提前致谢。

我尝试过以下代码并且已经有效了。从fiddle退房。别忘了从layerswitcher中选择Image layer。

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));

我希望它可以帮助你...
