Stroke 超越了 SVG 画布

  • 772

使用strokesvg 时，它会超出视图框。如何解决？

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 441 394.36">
  <path fill="none" stroke="black" stroke-width="35" d="M329.9,1.5c60.56,0,109.6,49.03,109.6,109.47c0,109.47-109.6,171.8-219.06,281.27C110.97,282.77,1.5,220.44,1.5,110.97C1.5,50.53,50.54,1.5,110.97,1.5c54.73,0,82.1,27.37,109.47,82.1 C247.8,28.87,275.17,1.5,329.9,1.5z" />

  1. 我想有必要viewBox="-16 -16 474 433"吗？

    body {margin: 0; padding: 0;}
    <svg xmlns="http://www.w3.org/2000/svg" viewBox="-16 -16 474 433">
  <path fill="none" stroke="black" stroke-width="35" d="M329.9,1.5c60.56,0,109.6,49.03,109.6,109.47c0,109.47-109.6,171.8-219.06,281.27C110.97,282.77,1.5,220.44,1.5,110.97C1.5,50.53,50.54,1.5,110.97,1.5c54.73,0,82.1,27.37,109.47,82.1 C247.8,28.87,275.17,1.5,329.9,1.5z" />

    很多情况下，使用“poke”方法无法捕获必要的参数viewBox

    在这种情况下，JS方法会有所帮助getBBox()

    <svg xmlns="http://www.w3.org/2000/svg" width="30%" height="30%" viewBox="0 0 441 394.36" style="border:1px solid red;">
  <path id="p1" fill="none" stroke="black" stroke-width="35"  d="M329.9,1.5c60.56,0,109.6,49.03,109.6,109.47c0,109.47-109.6,171.8-219.06,281.27C110.97,282.77,1.5,220.44,1.5,110.97C1.5,50.53,50.54,1.5,110.97,1.5c54.73,0,82.1,27.37,109.47,82.1 C247.8,28.87,275.17,1.5,329.9,1.5z" />
</svg> 
<script>
console.log(p1.getBBox());
</script>

    将结果值代入viewBox

    <svg xmlns="http://www.w3.org/2000/svg" width="30%" height="30%" viewBox="1.5 1.5 438 390.74" style="border:1px solid red;">
  <path id="p1" fill="none" stroke="black" stroke-width="1"  d="M329.9,1.5c60.56,0,109.6,49.03,109.6,109.47c0,109.47-109.6,171.8-219.06,281.27C110.97,282.77,1.5,220.44,1.5,110.97C1.5,50.53,50.54,1.5,110.97,1.5c54.73,0,82.1,27.37,109.47,82.1 C247.8,28.87,275.17,1.5,329.9,1.5z" />
</svg> 
<script>
console.log(p1.getBBox());
</script>

    但是它getBBox()显示了描述svg图形的矩形的参数而不考虑stroke-wifth我们有它34

    第二点 - 使用宽线，外部（线的一半）将超出 SVG 画布（红色边框），因此必须考虑这一点并相应更改参数viewBox

    这是根据计算getBBox() viewBox="1.5 1.5 438 390.74"添加34（每边半行）

    它变成了

    viewBox="-15.5 -15.5 472 424.74

    <svg xmlns="http://www.w3.org/2000/svg" width="30%" height="30%" viewBox="-15.5 -15.5 472 422.74" style="border:1px solid red;">
  <path id="p1" fill="none" stroke="black" stroke-width="34"  d="M329.9,1.5c60.56,0,109.6,49.03,109.6,109.47c0,109.47-109.6,171.8-219.06,281.27C110.97,282.77,1.5,220.44,1.5,110.97C1.5,50.53,50.54,1.5,110.97,1.5c54.73,0,82.1,27.37,109.47,82.1 C247.8,28.87,275.17,1.5,329.9,1.5z" />
</svg> 
<script>
console.log(p1.getBBox());
</script>
