应用背景过滤器:blur();到SVG路径 [英] Applying a backdrop-filter: blur(); to an SVG path

问题描述

我正在尝试使用SVG在CSS中重新创建效果.我们将文本另存为SVG，只需要模糊文本后面的背景即可.

I am trying to recreate an effect in CSS using an SVG. We have text saved as an SVG and needing to blur the backdrop behind the text only.

我知道通过应用 backdrop-filter:blur(10px); 的CSS样式，可以对块< div> 元素实现此操作，但是我无法使用SVG路径可获得相同的效果.

I know this is possible with block <div> elements by applying a css style of backdrop-filter: blur(10px);, but I am unable to get the same effect with SVG paths.

这是理想的效果

这是SVG的摘录

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg"
   xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
   width="1040.474px" height="209.154px" viewBox="0 0 1040.474 209.154"
   enable-background="new 0 0 1040.474 209.154"
   xml:space="preserve">
      <g opacity="0.4">

      </g>
</svg>

如何仅使字母后面的背景模糊?

How can you blur the backdrop behind the letters only?

推荐答案

使用 clipPath SVG并使用 blur 过滤器剪切重复的img，将为您提供以下信息:

using clipPath SVG and clipping a duplicate img with the blur filter will get you something like this:

body {
  margin 10px;
}

.clipped {
  position: absolute;
  top: 10px;
  left: 10px;
  clip-path: url(#svgTextPath);
  filter: blur(10px);
}

<img src="https://picsum.photos/id/99/500/300">
<img class="clipped" src="https://picsum.photos/id/99/500/300">

<svg height="0" width="0">
    <defs>
        <clipPath id="svgTextPath">
            <text x="50" y="200" textLength="400px" font-family="Vollkorn" font-size="200px" font-weight="700"> Text </text>
        </clipPath>
    </defs>
</svg>
