[OpenLayers-Users] Possibility to put a tiled image on OpenLayers

[Jimmy Aumard]

Thanks a lot Kris,

I have finally find the solution. This is my getURL function :

 getURL: function(bounds) {

        var res = this.map.getResolution();
        var bbox = this.maxExtent;
        var size = this.tileSize;
        var tileX = Math.round((bounds.left - bbox.left) / (res * size.w));
        var tileY = Math.round((bounds.bottom - bbox.bottom) / (res *
size.h));
        var z = this.map.getZoom();
        /**
         * Zero-pad a positive integer.
         * number - {Int}
         * length - {Int}
         *
         * Returns:
         * {String} A zero-padded string
         */
        function zeroPad(number, length) {
            number = String(number);
            var zeros = [];
            for(var i=0; i<length; ++i) {
                zeros.push('0');
            }
            return zeros.join('').substring(0, length - number.length) +
number;
        }
        tileY = Math.ceil(this.zoomImages[z][1]/size.h) - tileY -1;
        var pos= parseInt(tileY) * Math.ceil(this.zoomImages[z][0]/size.w) +
parseInt(tileX);

        var components = [this.layername];
        var path = components.join('/');
        var url = this.url;
        if (url instanceof Array) {
            url = this.selectUrl(path, url);
        }
        url = (url.charAt(url.length - 1) == '/') ? url : url + '/';

        return url + path+"/"+this.layername+"_"+(z)+"_"+zeroPad(pos,4) +
'.' + this.extension;
    },

It's work for tiles like layerName_NbZoom_nbTile.extension.
Tile are like:

1 2 3 4
5 6 7 8

Hope this help  someone else.

Cheers

Jim
