Internet Explorer和clip-path

Question

据我所知，正如许多文章和CSS遮罩教程中展示的那样，clip-path应该可以在IE中使用。

然而，我无法使下面的内容在IE上正常运行，但在Chrome上可以正常工作。

.container {
  position: relative;
  width: 240px;
  height: 500px;
  left: 50%;
  top: 50%;
}

.pentagon {
  -webkit-clip-path: polygon(0px 0px, 100px 0px, 112px 13px, 240px 13px, 240px 250px, -250px 250px);
  -o-clip-path: polygon(0px 0px, 100px 0px, 112px 13px, 240px 13px, 240px 250px, -250px 250px);
  -ms-clip-path: polygon(0px 0px, 100px 0px, 112px 13px, 240px 13px, 240px 250px, -250px 250px);
  float: left;
}

.avatar {
  margin-top: 50px;
}

html {
  text-align: center;
  min-height: 100%;
  background: linear-gradient(white, #ddd);
}

h1,
p {
  color: rgba(0, 0, 0, .3);
}

<div class="container">
  <div class="avatar">
    <img class="pentagon" src="http://25.media.tumblr.com/tumblr_m5nre6cxkQ1qbs7p5o1_r1_500.jpg" alt="" />
  </div>
</div>

<svg>
  <defs>
    <clipPath id="pentagon" clipPathUnits="objectBoundingBox">
      <polygon points=".5,0 1,.30 .2,1 .2,1 0,.30" />
    </clipPath>
  </defs>
</svg>

IE的哪个版本？SVG被IE9+支持。 - drip

它支持IE9及以上版本，这就是为什么我感到惊讶，虽然应该可以工作，但在我的端上却没有成功。 - Eric

Answer 1

经过更深入的研究，直接操作图片时，IE仅支持矩形形状的剪辑，而不支持clipPath复杂形状。

我的解决方案是将图像添加到SVG中，如下所示，这次在Chrome和IE9+中都可以使用。

演示 JsFiddle

body {
  background-color: #e0e0e0;
}

#image-wrapper {
  position: relative;
}

.svg-background,
.svg-image {
  clip-path: url(#clip-triangle);
}

.svg-image {
  -webkit-transition: all 0.5s ease 0.2s;
  -moz-transition: all 0.5s ease 0.2s;
  opacity: 1;
  transition: all 0.5s ease 0.2s;
}

svg.clip-svg {
  height: 250px;
  position: absolute;
  width: 250px;
}

#svg-1 {
  left: 0px;
  top: 0px;
}

<div id="image-wrapper">
  <svg id="svg-1" class="clip-svg">
        <rect class='svg-background' width="300" height="300" fill="#ffffff" />
        <image id="img-1" class='svg-image' width="300" height="300" xlink:href="http://25.media.tumblr.com/tumblr_m5nre6cxkQ1qbs7p5o1_r1_500.jpg" />
    </svg>
</div>
<svg id="svg-defs">
    <defs>
        <clipPath id="clip-triangle">
            <polygon points="0 0, 100 0, 112 13, 240 13, 240 250, -250 250"/>
        </clipPath>
    </defs>
</svg>

我创建了一个我认为更清晰的分支，链接如下：https://jsfiddle.net/2wu0dwrL/ - icicleking

但是如果图像具有响应式大小，似乎它将无法工作。对吗？ - Kenneth Chan

这个在苹果和iOS设备上能用吗？我的研究显示不行：https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path - Jeff Wilkerson

它可以在iOS 11、Windows 10 / IE 11、Chrome 87、FF 76.0.1上运行。 - Paul Brady

Answer 2

看看这个Demo JsFiddle，它支持响应式图片并且有很好的文档记录

    .member-picture {
      width: 200px; /*Final image width*/
    }
    
    .member-picture image{
      width:100%; /*for responsive image behaviour*/
      clip-path: url('#small-clip');
    }

  <svg class="member-picture">
      <image xlink:href="https://via.placeholder.com/350x200"></image>
  </svg>
  <svg viewBox="0 0 250.35696 212.65134"> <!--viewBox = "X1 Y1 X2 Y2"-->
    <defs>
      <clipPath id="small-clip" clipPathUnits="objectBoundingBox"
                  transform="scale(.0039 .0047)">
                  <!--Use clipPathUnits="objectBoundingBox" and transform="scale(1/(viewBox.X2-viewBox.X1) 1/(viewBox.Y2-viewBox.Y1)" -->
