The words are clipped to get four coordinates, ie the upper left corner of the horizontal crop box, upper left corner of the crop box and right coordinates, width and crop frame crop box is high. The initial state of the crop box is bound to crop the picture and the width and height related, look at your js code to get into the original image width and height are correct.
