Library to load, manipulate, and merge SVGs?

<p>I know there&#39;s github.com/ajstarks/svgo for generating SVGs, but it doesn&#39;t appear to allow for taking pieces of existing SVG files, changing them, and adding them to another SVG.</p> <p>Anyone know of a library that does this?</p> <hr/>**评论：**<br/><br/>abergmeier: <pre><p>Was searching for the same a while back and short answer is AFAIK there is none. Basically the choices you have are:</p> <ol> <li>Use C++ (e.g. <a href="https://github.com/svgpp/svgpp" rel="nofollow">svgpp</a>) when you need speed</li> <li>Use Chrome Headless when you just want to get it done.</li> </ol></pre>
