Examples
Accessing the yChannelSelector attribute
In this example, the <feDisplacementMap> element defined in the <filter> includes a yChannelSelector attribute.
html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<defs>
<filter id="displacementFilter">
<!-- Displacement Map with yChannelSelector set to Red Channel -->
<feDisplacementMap in="SourceGraphic" scale="20" yChannelSelector="G">
<feFuncR type="table" tableValues="0 1" />
</feDisplacementMap>
</filter>
</defs>
<rect
x="20"
y="20"
width="100"
height="100"
fill="green"
filter="url(#displacementFilter)" />
</svg>
We can access the yChannelSelector attribute and get its value:
js
const displacementMap = document.querySelector("feDisplacementMap");
console.log(displacementMap.yChannelSelector.baseVal); // Output: 2 (SVG_CHANNEL_G)
