大佬教程收集整理的这篇文章主要介绍了如何使用 php 或 JavaScript 从 svg 中删除白色填充，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我想知道如何从这个具有透明背景的 svg 中去除白色填充物。在 png 的情况下，我们有像素，并在像素数据上使用循环，我们可以针对白色像素来删除它们。但是在 svg 中我们没有像素所以不知道如何定位那些白色填充

在您问题的代码中，8 中的孔是不同的路径。为了使它成为一个真正的洞，我通过组合 d 属性合并了 2 条路径。
但是，它可能不适用于您代码中的所有路径。试一试，让我知道它是如何工作的。
请注意，在合并 2 d 属性时，我已将初始的 m 命令更改为 M。
另外：在这种情况下，fill-rule="evenodd" 不是必需的，但它可能有助于其他路径。
