Here are the images 和 here is the generating html + svg(您可能需要在结果窗口中向下滚动一点)

顺便说一下，如果您将 Chrome 页面的缩放比例降低到 75% 或更少，渲染效果会好很多，但仍然不正确。

我做错了什么还是这是一个已知的 Chrome 错误？我一直无法在 Chromium 错误跟踪器中找到它。任何已知的解决方法？

Answer 1

要解决 Chrome 的错误，您可以应用 spreadMethod="reflect" ...

    <defs>
      <linearGradient id="gradient0" x1="0" y1="0%" x2="4.3478260869565215%" y2="0%" spreadMethod="reflect">
        <stop offset="0" stop-color="#000000"></stop>
        <stop offset="1" stop-color="#ffffff"></stop>
      </linearGradient>
    </defs>
