Creates an instance of Image out of an object makes use of toCanvasElement. Once this method was based on toDataUrl and loadImage, so it also had a quality and format option. toCanvasElement is faster and produce no loss of quality. If you need to get a real Jpeg or Png from an object, using toDataURL is the right way to do it. toCanvasElement and then toBlob from the obtained canvas is also a good option.
Parameters
• options?: ObjectToCanvasElementOptions
for clone as image, passed to toDataURL
