Question

我尝试模糊SVG剪切路径没有成功。我尝试了其他解决方案，但没有一个奏效。我不确定match /documents/{docid} { allow read: if ( request.resource.userParams.accessBy == 'teams' && get(/user/<userId>).teams.has(request.resource.userParams.value) && get(/teams/<request.resource.userParams.value>).docs.hasAny(resource.data.rights) || request.resource.userParams.accessBy == 'company' && get(/user/<userId>).company == request.resource.userParams.value && get(/company/<request.resource.userParams.value>).docs.hasAny(resource.data.rights) ) }之外是否还有其他解决方案。

Answer 1

好的，这是一种使用radial-gradient()作为mask-image的方法。

var h1 = document.getElementById('masked');

document.addEventListener('mousemove', mouseListen, false);

function mouseListen(e){ 
  setMaskPos(e.clientX,e.clientY);
}

function setMaskPos(x,y) {
  h1.setAttribute("style", "-webkit-mask-image: radial-gradient(circle at " + x + "px " + y + "px, black 0px, black 200px, transparent 250px)");
}

// Initialise the mask off screen
setMaskPos(-999,0);

.wrapper {
  display: flex;
  justify-content: center;
  align-items: center;
  position: relative;
}

.h1, blur {
  width: 100vw;
  height: 100vh;
}

.h1 {
  position: absolute;
  top: 0;
  left: 0;
  margin: 0;
  padding: 0;
  font-size: 4em;
  background-color: white;
}

.blur {
  position: absolute;
  top: 0;
  left: 0;
  margin: 0;
  padding: 0;
  font-size: 4em;
  background-color: white;
  filter: blur(8px)
}

使用<mask>而不是<clipPath>。剪切路径不能模糊，但是<mask>中的元素可以。

以下内容将在Firefox中运行，但在其他浏览器中将被破坏：

.wrapper {
  display: flex;
  justify-content: center;
  align-items: center;
  position: relative;
}
    
.h1, .blur {
  width: 100vw;
  height: 100vh;
}
    
.h1 {
  position: absolute;
  top: 0;
  left: 0;
  margin: 0;
  padding: 0;
  font-size: 4em;
  -webkit-mask: url(#svgPath);
  mask: url(#svgPath);
  background-color: blue;
}
    
.blur {
  position: absolute;
  top: 0;
  left: 0;
  margin: 0;
  padding: 0;
  font-size: 4em;
  color: blue;
  background-color: white;
  filter: blur(8px)
}

<div class="wrapper">
  <h1 class="blur">
    Our principles inform everything we do. Whether you're preparing content, designing an interface or developing an entire service, start by reading these.
  </h1>
  <h1 class="h1">

  </h1>
</div>
    
<svg id="googlesMain" height="0" width="0">
  <defs>
    <filter id="f1" x="0" y="0">
      <feGaussianBlur in="SourceGraphic" stdDeviation="15" />
    </filter>
    <mask id="svgPath">
      <circle id="clipPath" cx="250" cy="250" r="250" fill="white" filter="url(#f1)"/>
    </mask>
  </defs>
</svg>

要使其在其他浏览器中运行，请尝试将其转换为独立的SVG。然后改用mask-image CSS规则。

<svg xmlns="http://www.w3.org/2000/svg">
  <defs>
    <filter id="f1" x="0" y="0">
      <feGaussianBlur in="SourceGraphic" stdDeviation="15" />
    </filter>
  </defs>
  <circle cx="250" cy="250" r="250" fill="white" filter="url(#f1)" />
</svg>

使用CSS：

.h1 {
  ...
  -webkit-mask-image: url(mask.svg);
  mask-image: url(mask.svg);
  ...
}
