[OpenLayers-Users] OL 4.2 with TypeScript:How to extend index.d.ts?

[Ignacio Talavera]

Thanks, Finally I found a workaround instead of invoking *getFullTileRange *
method.


strategy: ol.loadingstrategy.tile(tileGrid),
url: function(extent, resolution) {
        var tileCoord = tileGrid.getTileCoordForCoordAndResolution(
ol.extent.getCenter(extent), resolution);
        var z = tileCoord[0];
        var x = tileCoord[1];
        var y = tileCoord[2];
        *//var range = tileGrid.getFullTileRange(z);*
*        y = **Math.pow(2, z) + y;**//range.getHeight() + tileCoord[2];*
        return '/geoserver/gwc/service/tms/1.0.0/' +layer
+'@EPSG%3A'+projection_epsg_no+'@geojson/'+z+'/'+ x+'/'+ y+'.geojson';
   }
