如何在SVG路径中居中文本

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

 <svg height="500"width="500">

Answer 1

你是那里的一部分,但你犯了一些错误.

text-anchor="center"是错的.它应该是text-anchor="middle".

此外,您应该添加startOffset="50%"到<textPath>元素以指定文本应该在路径的中间点居中.

最后,您需要修复路径本身.您需要删除Z路径描述末尾的path命令.您只需要弧,而不是返回到弧的起点的返回线.

<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

在这里，我将六个文本放置在一条路径上。该路径是一个完整的圆（弧），长度 ( pathLength) 为 12。零位于 12 点钟方向。首先startOffset是 1，然后是 1，依此类推。文本锚定在中间。“披萨片”是由<circle>被掩盖的披萨片制成的。掩模由三个<rect>倾斜和旋转的 s 组成。

这是尽可能干净的。

<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>
