Can this code be set up to be able to use an image url instead?

[javascriptcoding5678]

Instead of choosing a file, I would place the image url somewhere in the code.

code: https://jsfiddle.net/zka8vtow/1/

var URL = window.URL;
var cvs = document.getElementById('canvas');
var ctx = cvs.getContext('2d');
var res = document.getElementById('results');

cvs.addEventListener('mousemove', mousePos, false);

window.onload = function() {
  var inputImage = document.getElementById('inputImage');
  inputImage.addEventListener('change', handleImageFiles, false);
}

function mousePos(evt) {
  var rect = cvs.getBoundingClientRect();
  var x = parseInt(evt.clientX - rect.left);
  var y = parseInt(evt.clientY - rect.top);
  var p = ctx.getImageData(x, y, 1, 1).data;
  results.innerHTML = '<table style="width:100%;table-layout:fixed"><td>X: ' +
    x + '</td><td>Y: ' + y + '</td><td>Red: ' +
    p[0] + '</td><td>Green: ' + p[1] + '</td><td>Blue: ' +
    p[2] + '</td><td>Alpha: ' + p[3] + "</td></table>";
  return {
    x,
    y
  };
}

function handleImageFiles(e) {
  var url = URL.createObjectURL(e.target.files[0]);
  var img = new Image();
  img.onload = function() {
    cvs.width = img.width;
    cvs.height = img.height;
    ctx.drawImage(img, 0, 0);
  }
  img.src = url;
}

I don’t understand what you want to do. Can you be more specific?
