How to use measuring on (raster with kml) openlayer v3? -


i'm using open layer v3, in script:

var raster = new ol.layer.tile({          source: new ol.source.bingmaps({             imageryset: 'aerial',             key: '---'         })     }); var vector = new ol.layer.vector({         source: new ol.source.vector({             url: 'url',             format: new ol.format.kml()          })     }); var map = new ol.map({                                  controls: ol.control.defaults().extend([     new ol.control.fullscreen()                                  ]),         layers: [ raster,  vector],         target: document.getelementbyid('map'),         view: new ol.view({             center: [5379788.7775 , 3658497.76290000044  ],             projection: projection,             zoom: 10         })     });

i don't know how add measuring on layers, sample in open layer supports measuring layer on raster (i can't have both of kml , measuring)
