如何绘制图像Angular2 Ionic2

我知道如何在Angular1 Ionic1中绘制.

在我的HTML中:

<img ng-src="{{image}}" style="width: 100%">
<canvas id="tempCanvas"></canvas>
Run Code Online (Sandbox Code Playgroud)

在我的控制器中

var startimg="img/face.jpg";
$scope.image=startimg;

var canvas = document.getElementById('tempCanvas');
var context = canvas.getContext('2d');

var source =  new Image();
source.src = startimg;

canvas.width = source.width;
canvas.height = source.height;

console.log(canvas);

context.drawImage(source,0,0);

context.font = "100px impact";

textWidth = context.measureText($scope.frase).width;
if (textWidth > canvas.offsetWidth) {
    context.font = "40px impact";
}

context.textAlign = 'center';
context.fillStyle = 'white';             
context.fillText('HELLO WORLD',canvas.width/2,canvas.height*0.8);

var imgURI = canvas.toDataURL();

$timeout( function(){
    $scope.image = imgURI;
}, 200);

这段代码肯定会在人脸图像的顶部绘制HELLO WORLD文本.

但是,在Ionic2/Angular2中,它似乎不起作用.我甚document.getElementById('tempCanvas')至无法上班.

请帮忙. …
