我是否可以在此代码段中为svg图片元素添加笔划?
<div style="width:100%; height:100%;">
<svg style="width:100%; height:100%;">
<g>
<clipPath id="myclippath" clipPathUnits="objectBoundingBox">
<polygon points="0 0, 0.4 0, 0.5 0.5, 0.6 0, 1 0, 1 1, 0 1" />
</clipPath>
</g>
<image x="0" y="0" width="100%" height="100%" clip-path="url(#myclippath)"
xlink:href="https://a248.e.akamai.net/assets.github.com/images/modules/logos_page/Octocat.png" />
</svg>
</div>
