I am using an image to display my map with OpenLayers. My JS code looks like this:
map = new OpenLayers.Map('map');
var options = {numZoomLevels: 7,
isBaseLayer: true,
};
var globe = new OpenLayers.Layer.Image(
'Globe ESA',
'http://upload.wikimedia.org/wikipedia/commons/0/07/World_map_blank_black_lines_4500px.gif',
new OpenLayers.Bounds(-180, -90, 180, 90),
new OpenLayers.Size(4500, 2234),
options);
map.addLayers(globe);
markers = new OpenLayers.Layer.Markers("markers");
map.addLayer(markers);
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.zoomToMaxExtent();
map.addControl(new OpenLayers.Control.MousePosition());
My CSS is:
#map {
width: 640px;
height: 480px;
border: 1px solid black;
}
But I can't get OpenLayers to scale down the large image. It is always display at full resolution and I can't zoom out to display the whole globe. Help please.
