Did anyone try to save images from bookwalker’s web browser-based viewer? It paints the images on a canvas. Tried calling toBlob and toDataURL, but got a SecurityError. I guess life isn’t that simple. :/ The JS code is too much of a mess for me to read.
Edit: Okay, whatever. I can right-click on the canvas element in Firefox’s DOM viewer and there‘s a copy option. I just need a way to set the canvas to the right size somehow.
