I configured a WMTS layer with GeoWebCache, reading a WMS output of my organization.

The WMTS service is public:

http://cartoweb.cma.gva.es/geowebcache/service/wmts

The layer is Ortofoto_ICV.

When I put the layer as a custom Layer (WMTS), the layer is viewed properly (image:wmts_perso_layer.jpg)

And the code for the layer properties:

dojo.declare("ogc.WMTSLayer_Orto", esri.layers.TiledMapServiceLayer, { // create WMTSLayer by extending esri.layers.TiledMapServiceLayer
constructor: function() {
this.spatialReference = new esri.SpatialReference({wkid: 25830});
this.initialExtent = new esri.geometry.Extent(400000, 4100000, 1100000, 4600000, this.spatialReference);
this.fullExtent = new esri.geometry.Extent(400000, 4100000, 1100000, 4600000, this.spatialReference);
//
this.tileInfo = new esri.layers.TileInfo({
"dpi": "96",

"compressionQuality": 0,
"spatialReference": {"wkid": "25830"},

});
this.loaded = true;
this.onLoad(this);
},

getTileUrl: function(level, row, col) {
return "http://cartoweb.cma.gva.es/geowebcache/service/wmts" + "?SERVICE=WMTS&VERSION=1.0.0&REQUEST=GetTile" + "&LAYER=Ortofoto_ICV" + "&STYLE=_null" + "&FORMAT=image/jpeg" + "&TILEMATRIXSET=EPSG:25830" + "&TILEMATRIX=" + level + "&TILEROW=" + row + "&TILECOL=" + col;
}
});


But If I put the layer as a WMTS Layer, the image have an offset (see image: wmts_layer.jpg) with the same settings.

The code is:

var tileInfo1 = new esri.layers.TileInfo({
"dpi": "96",
"format": "image/jpeg",
"compressionQuality": 0,
"spatialReference": new esri.SpatialReference({"wkid": 25830}),
"height": 200,
"width": 200,
"origin": {
"x": 400000,
"y": 4600000
},

});
var tileExtent1 = new esri.geometry.Extent(400000, 4100000, 1100000, 4600000, new esri.SpatialReference({wkid: 25830}));
var layerInfo_Orto = new esri.layers.WMTSLayerInfo({
tileInfo: tileInfo1,
fullExtent: tileExtent1,
initialExtent: tileExtent1,
identifier: "Ortofoto_ICV",
tileMatrixSet: "EPSG:25830",
format: "jpeg",
style: "_null"
});
var options_Orto = {
id: "Web_Ortofoto",
visible: true,
serviceMode: "KVP",
layerInfo: layerInfo_Orto
};
var CapaOrtofoto = new esri.layers.WMTSLayer("http://cartoweb.cma.gva.es/geowebcache/service/wmts", options_Orto);

What is wrong in definition of WMTS layer?

Another problem is when I zoom or Pan, the WMTS Layer hides.

The property "visible: true" in "options_Orto" is correct?

Thanks in advance.
