圆圈内的SVG图像

Question

我想创建一个包含图像的圆圈，我已经尝试过使用pattern或filter，但没有一个给我预期的结果。下面是代码：

<svg id="graph" width="100%" height="400px"> 
 

 
    <!-- filter --> 
 
    <filter id = "born1" x = "0%" y = "0%" width = "100%" height = "100%"> 
 
     <feImage xlink:href = "https://cdn3.iconfinder.com/data/icons/people-professions/512/Baby-512.png"/> 
 
    </filter> 
 
    <circle id = "born" class = "medium" cx = "5%" cy = "20%" r = "5%" fill = "white" stroke = "lightblue" stroke-width = "0.5%" filter = "url(#born1)"/> 
 
    
 
    <!-- pattern --> 
 
    <defs> 
 
    <pattern id="image" x="0" y="0" height="100%" width="100%"> 
 
     <image x="0" y="0" xlink:href="https://cdn3.iconfinder.com/data/icons/people-professions/512/Baby-512.png"></image> 
 
    </pattern> 
 
    </defs> 
 
    <circle id = "sd" class = "medium" cx = "5%" cy = "40%" r = "5%" fill = "white" stroke = "lightblue" stroke-width = "0.5%" fill="url(#image)"/> 
 
</svg>

我的目标是保护圈，让背景图片里面，像CSS ATTR background-image。

Answer 1

模式才能正常工作。你只需要给<image>一个大小。与HTML不同，SVG图像默认为宽度和高度为零。

此外，如果您想让图像与圆形一起缩放，那么您应该为图案指定一个viewBox。

<svg id="graph" width="100%" height="400px"> 
 

 
    <!-- pattern --> 
 
    <defs> 
 
    <pattern id="image" x="0%" y="0%" height="100%" width="100%" 
 
      viewBox="0 0 512 512"> 
 
     <image x="0%" y="0%" width="512" height="512" xlink:href="https://cdn3.iconfinder.com/data/icons/people-professions/512/Baby-512.png"></image> 
 
    </pattern> 
 
    </defs> 
 
    
 
    <circle id="sd" class="medium" cx="5%" cy="40%" r="5%" fill="url(#image)" stroke="lightblue" stroke-width="0.5%" /> 
 
</svg>

Answer 2

试试这个，

使用patternUnits="userSpaceOnUse"并设置height="100%" width="100%"<image>的

<defs> 
    <pattern id="image" x="0" patternUnits="userSpaceOnUse" y="0" height="100%" width="100%"> 
     <image x="0" y="0" width="500" height="500" xlink:href="http://www.viralnovelty.net/wp-content/uploads/2014/07/121.jpg"></image> 
    </pattern> 
    </defs>
