Thank you, but couldn´t find the action to load an image (or userMedia snapshot) to canvas. Load snapshot canvas doesn´t work for this. Any idea?
To crop an image after loading it you would need to first load the image into a sprite, then size the drawing canvas to the size of the crop, position it over the sprite, then paste the object. Since it only pastes the parts of the object within the bounds of the canvas, this works like cropping
