Usage of createImageData()

Hello,

I want to use image data as input of Tensorflow : image = _tfnode.node.decodeImage( imageData);

For my side, data is coming from a webbrowser as following :
```
canvasElement.toBlob( function (blob) {
let src = canvasElement.toDataURL("image/png");
ws.send( { src: src, width: canvasElement.width, height: canavasElement.height } );
...
```
So I send this message to an other application (through websocket), and then, nn reception of 'receivedMessage':
```
function dataURLToBlob( dataURL) {
let datas = dataURL.split( ",");
let buffer1 = Buffer.from(datas[1]);
let buffer = Uint16Array.from(buffer1);
return buffer;
}
const myUint16ArrayBuffer = dataURLToBlob( receivedMessage.imgSrc);
const imageData = createImageData( myUint16ArrayBuffer, receivedMessage.width, receivedMessage.height);
```
So, what should I do with 'imageData' to create a canvas ?

Best regards.
