Examples

Accessing the xChannelSelector attribute

In this example, the <feDisplacementMap> element defined in the <filter> includes a xChannelSelector attribute.

html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <filter id="displacementFilter">
      <!-- Displacement Map with xChannelSelector set to Red Channel -->
      <feDisplacementMap in="SourceGraphic" scale="20" xChannelSelector="R">
        <feFuncR type="table" tableValues="0 1" />
      </feDisplacementMap>
    </filter>
  </defs>
  <rect
    x="20"
    y="20"
    width="100"
    height="100"
    style="fill:red;"
    filter="url(#displacementFilter)" />
</svg>

We can access the xChannelSelector attribute and get its value:

js
const displacementMap = document.querySelector("feDisplacementMap");

console.log(displacementMap.xChannelSelector.baseVal); // Output: 1 (SVG_CHANNEL_R)
