I'm trying to create an application for my Nokia N900 that uses offline<br/>
maps too. I found the following solution:<br/>
<br/>
var tms = new OpenLayers.Layer.TMS( "TMS", "", {<br/>
type: 'png',<br/>
getURL: my_getTileURL, // <------------+<br/>
alpha: true, // |<br/>
isBaseLayer: true // |<br/>
}); // |<br/>
// |<br/>
function my_getTileURL(bounds) { // <---+<br/>
var res = this.map.getResolution();<br/>
var x = Math.round((bounds.left - this.maxExtent.left) / (res *<br/>
this.tileSize.w));<br/>
var y = Math.round((bounds.bottom - this.tileOrigin.lat) / (res *<br/>
this.tileSize.h));<br/>
var z = this.map.getZoom();<br/>
if (mapBounds.intersectsBounds( bounds ) && z >= mapMinZoom && z <=<br/>
mapMaxZoom ) {<br/>
console.log( this.url + z + "/" + x + "/" + y + "." + this.type);<br/>
return 'file:///<tiles_directory>/'+this.url + z + "/" + x + "/" + y +<br/>
"." + this.type;<br/>
} else {<br/>
return "empty_image.png";<br/>
}<br/>
}<br/>
<br/>
I hope this helps.<br/>
<br/>
Best regards<br/>
<br/>
