Question

I was trying to make rounded corners for s svg:image (image embedded in SVG) with d3.js. I can’t find out how to properly style the image, because according to W3C spec I should be able to use CSS, but neighter border nor rounded edges work for me.

Thanks in advance.

  vis.append("svg:image")
     .attr("width", width/3)
     .attr("height", height-10)
     .attr("y", 5)
     .attr("x", 5)      
     .attr("style", "border:1px solid black;border-radius: 15px;")
     .attr("xlink:href",
           "http://www.acuteaday.com/blog/wp-content/uploads/2011/03/koala-australia-big.jpg");

‘border-radius’ doesn’t apply to svg:image elements (yet anyway). A workaround would be to create a rect with rounded corners, and use a clip-path.

An example.

The relevant part of the source:

<defs>
    <rect id="rect" x="25%" y="25%" width="50%" height="50%" rx="15"/>
    <clipPath id="clip">
      <use xlink:href="#rect"/>
    </clipPath>
  </defs>

  <use xlink:href="#rect" stroke-width="2" stroke="black"/>
  <image xlink:href="boston.jpg" width="100%" height="100%" clip-path="url(#clip)"/>

It’s also possible to create several rect elements instead of using <use>.
