Image resolution

I have the following code used to resize a base64Image. When I do the resize, it is a smaller file, but when I try display the image, it is just pitch black.

Any ideas what i am doing incorrectly? Thanks

resize(base64Img, width, height) {
    var img = new Image();
    img.src = 'data:image/jpeg;base64,'+base64Img;
    var canvas = document.createElement('canvas'),ctx = canvas.getContext('2d');
    canvas.width = width;
    canvas.height = height;
    ctx.drawImage(img, 0, 0, width, height);
    return canvas.toDataURL("image/jpeg");


this.base64Image = this.resize(this.base64Image, 100, 100);


<img src="{{ base64Image }}" />


img.src = 'data:image/jpeg;base64,'+base64Img;

should be

img.src = base64Img;
