Examples
Accessing the scale attribute
In this example, the <feDisplacementMap> element defined in the <filter> includes a scale attribute.
html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
<defs>
<filter id="filter1">
<!-- Displacement Map -->
<feDisplacementMap in="SourceGraphic" scale="20">
<feFuncR type="table" tableValues="0 1" />
</feDisplacementMap>
</filter>
</defs>
<rect
x="20"
y="20"
width="100"
height="100"
fill="red"
filter="url(#filter1)" />
</svg>
We can access the scale attribute and get its value:
js
const displacementMap = document.querySelector("feDisplacementMap");
console.log(displacementMap.scale.baseVal); // Output: 20
