Image.src and revokeObjectURL

Seems as though I can do this:

            if(typeof child.material.map.image.src !== 'undefined'){
  				imageSrc = child.material.map.image.src;
  			}else{
  				
  				let img = child.material.map.image;
  				let canvas = document.createElement('canvas');
  				canvas.width = img.width;
  				canvas.height = img.height;
  				
  				let ctx = canvas.getContext('bitmaprenderer');
  				if(ctx) {
  					ctx.transferFromImageBitmap(img);
  				}
  				else {
  					canvas.getContext('2d').drawImage(img,0,0);
  				}
  				imageSrc = canvas.toDataURL();
  				canvas = null;
  				ctx = null;
  			}

This will allows me to get the data without having to edit the modules.
