How to draw an image on a canvas loaded from another site via crossOrigin Anonymous and get the url of that canvas?

Question

PHP

There is a canvas on which you need to display an image and get the code of this canvas and the code that in theory does this:
codepen.io/anon/pen/jWypLN?editors=101
It turns out that the image is displayed, but the canvas code cannot be obtained. If you add crossOrigin = Anonymous to the image, then the image is not displayed at all.
How to fix it so that it works?
