The component SCREENGRABBER is an invisible component that generates a screenshot and sends this screenshot as PNG file to the server side.

It internally is based on the framework "html2canvas" (https://github.com/niklasvh/html2canvas) which does an amazing job to transfer a DOM tree into a canvas-drawing. But: it is not perfect and not all HTML-/CSS-features are recognized in a proper way. So: please test the component within you scenario first!
