This sample shows how to setup an <code>elementFinished</code> option for <a>Diagram.makeSvg</a> that will replace the
|
|
SVG <code><image></code> tag's <code>href</code> with a Base64 URI instead of pointing to the <a>Picture.source</a>.
|
|
This can be useful to reduce external dependencies within your exported SVG.
