我需要帮助，当我使用svg绘制一个圆形并放置一些文本时，如何在SVG路径内居中文本

获取路径的边界框，适当设置文本的x、y坐标。 - Robert Longson

我在此将六个文本放在一条路径上。路径是一个完整的圆（弧），长度为12(pathLength)。0点钟位置是在12点方向。第一个startOffset是1，以此类推。文本位于中心处。"披萨片"由被遮罩的<circle>制成。遮罩由三个倾斜和旋转的<rect>组成。

这是最简洁的描述。

<svg viewBox="0 0 100 100" height="500" width="500">
  <defs>
    <path id="p1" d="M50 10 a 40 40 1 1 0 1 0" pathLength="12" />
    <mask id="m1">
      <g transform="translate(50 50) rotate(15)">
        <rect id="r1" width="50" height="50" fill="white"
          transform="skewX(15) skewY(15)" />
        <use href="#r1" transform="rotate(120)"/>
        <use href="#r1" transform="rotate(240)"/>
      </g>
    </mask>
  </defs>
  <circle cx="50" cy="50" r="50" fill="#ddd" mask="url(#m1)"/>
  <text font-size="6" text-anchor="middle">
    <textPath href="#p1" startOffset="1" side="right">1test text</textPath>
    <textPath href="#p1" startOffset="3" side="right">2test text</textPath>
    <textPath href="#p1" startOffset="5" side="right">3test text</textPath>
    <textPath href="#p1" startOffset="7" side="right">4test text</textPath>
    <textPath href="#p1" startOffset="9" side="right">5test text</textPath>
    <textPath href="#p1" startOffset="11" side="right">6test text</textPath>
  </text>
</svg>

例如，使用text-anchor属性，并将值设置为middle：

<svg width="250" height="250">
  <circle cx="125" cy="125" r="100" fill="#aeaeae" />
  <text x="50%" y="50%" text-anchor="middle" fill="white" font-size="100px" font-family="Arial" dy=".3em">BC</text>
Sorry, your browser does not support inline SVG.
</svg>

这会将文本放置在<svg>元素的中心，而不是路径的中心（正如OP所问）。 - ashleedawg

应该使用text-anchor="middle"。此外，您应该在<textPath>元素中添加startOffset="50%"，以指定文本应居中于路径的中点。

你已经完成了一部分，但是犯了一些错误。 text-anchor="center" 是不正确的。正确的应该是 text-anchor="middle"。

另外，你应该在 <textPath> 元素中添加 startOffset="50%"，以指定文本应位于路径的中间点居中显示。

最后你需要修复路径本身。你需要删除路径描述末尾的 Z 路径命令。你只想要弧线，而不是回到弧线起点的连线。
