如何使 SVG 路径中的文本居中

Question

我需要一些帮助，当我使用 svg 绘制一个循环并放置一些文本时，如何在 SVG 路径中居中文本

Answer 1

你已经完成了一部分，但你犯了一些错误。

text-anchor="center" 是错误的。应该是 text-anchor="middle".

此外，您应该在 <textPath> 元素中添加 startOffset="50%" 以指定文本应在路径的中点居中。

最后你需要修复路径本身。您需要删除路径描述末尾的 Z 路径命令。您只需要圆弧，而不是 return 线回到圆弧起点。

<svg height="500"width="500">
 
  <path d="M250 250 L250 0 A250,250,0,0,1,466.50635094610965,124.99999999999997  L250 250 Z" fill="#ddd" stroke="#ddd"></path>
  <defs>
    <path id="p1" d="M250 50 A200,200,0,0,1,423.2050807568877,149.99999999999997" fill="#ddd" stroke="#ddd"></path>
  </defs>
  <text style="font-size: 24px;">
    <textPath xlink:href="#p1" startOffset="50%" text-anchor="middle">1test text</textPath>
  </text>
  
</svg>

Answer 2

这里我把六个文本放在一个路径上。路径是一个完整的圆（弧），长度（pathLength）为 12。零在 12 点钟位置。首先 startOffset 然后是 1，依此类推。文本固定在中间。 “披萨片”是由蒙面的 <circle> 制成的。面具由三个 <rect> 倾斜和旋转组成。

这是最干净的了。

<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>

Answer 3

使用文本锚点属性，中间值例如：

<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>

Answer 4

应该是text-anchor="middle"。此外，您应该将 startOffset="50%" 添加到 <textPath> 元素以指定文本应在路径的中间点居中。
