-Your program could call neat TVG APIs while switching drawing context If you have your own drawing engine. During the API calls, ThorVG serializes drawing commands among the volatile paints' nodes then performs synchronous/asynchronous rendering using own backend raster engines. ThorVG supports vector images such as SVG, also expand supporting other popular formats on demand. On the rendering, it could spawn intermediate frame-buffers for compositing scenes only when it's necessary. The next figure shows you a brief strategy on how to use ThorVG on your system.<br />
