context.getImageData(0, 0, 100, 100).then(imageData =&gt; {
      const data = Object.values(imageData.data);
      const length = Object.keys(data).length;
      for (let i = 0; i &lt; length; i += 4) {
        data[i] = 0;
        data[i + 1] = 0;
        data[i + 2] = 0;
      }
      const imgData = new ImageData(canvas, data, 100, 100);
