如何将路径添加到剪辑路径 [英] How to add path to a clip path

问题描述

尝试向图像添加波浪效果时，我被卡住了.这两个 SVG，一个包含我试图实现的路径，第二个按预期运行，但剪辑路径/形状错误.当我粘贴到所需的路径中时，它不起作用.为什么以及如何使这项工作发挥作用?

When trying to add a wave effect to the image, I got stuck. These two SVGs, one contains the path that I am trying to implement, the second behaves as expected but has a wrong clip path/shape. When I paste in the desired path it dos not work. Why and how can I make this work?

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1441 742" fill="none">        
    <path  d="M0 740.5V0H1440.5V557C1369 549 1193.8 549.4 1073 615C922 
    697 809 702.5 698.5 685C611.987 671.299 465 603 286 677C142.8 736.2 35.6667 744 0 740.5Z" 
    fill="#001E61"/>
</svg>

工作示例但路径错误

img {
    clip-path: url(#svgClip);
    width: 100%;
    height: 800px;
    object-fit: cover;
    display: block;
    margin-right: auto;
    margin-left: auto;
}

推荐答案

正如您在工作示例中看到的，用于裁剪图像的路径有一个边界框 width:1 和 高度＜1.您需要缩小路径.

As you can see in the working example the path used to clip the image has a bounding box width:1 and height < 1. You will need to scale down your path.

所需路径的边界框是width:1441 height:742.我将路径缩放 0.00069 因为 1/1441 = 0.00069

The bounding box of the desired path is width:1441 height:742. I'm scaling the path by a factor of 0.00069 because 1 / 1441 = 0.00069

*{margin:0;padding:0;}
img{width:100%;-webkit-clip-path: url(#clip);
  clip-path: url(#clip);}

<svg class="chart" width="0" viewBox="0 0 1 0.852">
  
  <clipPath id="clip" clipPathUnits="objectBoundingBox">
    <path transform="scale(0.00069)" d="M0 740.5V0H1440.5V557C1369 549 1193.8 549.4 1073 615C922
