Question

我有一个带有CSS属性clip-path的图像。我添加了动画来旋转剪辑路径。我只想旋转剪切路径，而不是图像。从下面的代码中，您可以了解我想要实现的目标。我这样做是为了让您对我想要实现的目标有所了解。我的代码的问题在于，在每个关键帧上手动设置剪切路径点需要花费大量时间。那么，有没有一种简短的方法可以实现以下代码结果，而无需手动更改关键帧上的点？我希望它是平滑的，很难手动设置点来设置。（请记住，我不需要最后一个使图像不可见的动画，我无法弄清楚它为什么发生。

#profile-img {
    width: 15%;
    margin: 5%;
    -webkit-clip-path: polygon(20% 0%, 0% 20%, 30% 50%, 0% 80%, 20% 100%, 50% 70%, 80% 100%, 100% 80%, 70% 50%, 100% 20%, 80% 0%, 50% 30%);

将图像用作伪元素的背景，并向相反方向旋转：

.image {
    width:200px;
    height:200px;
    margin: 20px;
    -webkit-clip-path: polygon(20% 0%, 0% 20%, 30% 50%, 0% 80%, 20% 100%, 50% 70%, 80% 100%, 100% 80%, 70% 50%, 100% 20%, 80% 0%, 50% 30%);
    clip-path: polygon(20% 0%, 0% 20%, 30% 50%, 0% 80%, 20% 100%, 50% 70%, 80% 100%, 100% 80%, 70% 50%, 100% 20%, 80% 0%, 50% 30%);
    animation: clipRotateAnim 2s linear infinite;
    position:relative;
    overflow:hidden;
}
.image:before {
  content:"";
  position:absolute;
  top:-10%;
  bottom:-10%;
  left:-10%;
  right:-10%;
  background:var(--i) center/cover;
  animation: clipRotateAnim 2s linear infinite reverse;
}
@keyframes clipRotateAnim{
  from{transform:rotate(0)}
  to{transform:rotate(360deg)}
}

<div class="image"  style="--i:url(https://images.pexels.com/photos/1025804/pexels-photo-1025804.jpeg?auto=compress&cs=tinysrgb&h=350)">
</div>

避免使用clip-path的另一种方法是使用背景在旋转的图像上方创建另一个图层。在这种情况下，您将没有透明性，但是您将获得更好的浏览器支持。

.image {
    width:200px;
    height:200px;
    margin: 20px;
    position:relative;
   background:var(--i) center/cover;
   overflow:hidden;
}
.image:before {
  content:"";
  position:absolute;
  top:0;
  bottom:0;
  left:0;
  right:0;
  box-shadow:0 0 200px 200px #fff;
  background-image:
    linear-gradient(#fff,#fff),linear-gradient(#fff,#fff),linear-gradient(#fff,#fff),linear-gradient(#fff,#fff);
  background-size:calc(50% - 30px) calc(50% - 30px);
  background-position:top left,top right,bottom left,bottom right;
  background-repeat:no-repeat;
  animation: clipRotateAnim 2s linear infinite;
}
@keyframes clipRotateAnim{
  from{transform:rotate(0)}
  to{transform:rotate(360deg)}
}

<div class="image"  style="--i:url(https://images.pexels.com/photos/1025804/pexels-photo-1025804.jpeg?auto=compress&cs=tinysrgb&h=350)">
  
</div>

如何在不旋转图像的情况下旋转剪切路径？
