your javascript code valid typescript code, need tell compiler canvas of type htmlcanvaselement:

var canvas = document.getelementbyid('mycanvas') htmlcanvaselement; var context = canvas.getcontext('2d'); var imageobj = new image(); imageobj.onload = function () {     context.drawimage(imageobj, 69, 50);     context.font = "20px calibri";     context.filltext("my text!", 100, 200); };  imageobj.src = 'http://www.html5canvastutorials.com/demos/assets/darth-vader.jpg';
