Front Screenshot

This library bundles

• HTML2Canvas
• Canvg
• Cash.js

Into an library with no dependencies, that can transform SVG elements into images or Canvas elements, and take screenshots of your page or sections of it, even if they are hidden due to CSS properties such as overlay scroll, hidden or auto.

Why?

Basically, because chart libraries such as C3.js can style SVG elements with rotation and other transformations that HTML2Canvas cannot parse. So I combined its features with the ones on Canvg to preprocess a given container, transforming each SVG element into an image, then capturing the screenshot, then restoring the original SVG.

Some additions and removal of properties, attributes and classnames where cumbersome to add using native document.querySelectorAll methods, so I also bundled Cash.js, a minimal jQuery alternative that provides just what's needed to manipulate DOM nodes.
