SVGFEDisplacementMapElement: in1 property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The in1 read-only property of the SVGFEDisplacementMapElement interface reflects the in attribute of the given <feDisplacementMap> element.

Value

An SVGAnimatedString object.

Examples

In this example, two <feDisplacementMap> elements are defined in a filter, each with a different in attribute.

html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <filter id="filter1">
      <!-- First Displacement Map -->
      <feDisplacementMap in="SourceGraphic" scale="20">
        <feFuncR type="table" tableValues="0 1" />
      </feDisplacementMap>

      <!-- Second Displacement Map -->
      <feDisplacementMap in="BackgroundImage" scale="30">
        <feFuncR type="table" tableValues="0.5 1" />
      </feDisplacementMap>
    </filter>
  </defs>
  <rect
    x="20"
    y="20"
    width="100"
    height="100"
    style="fill:red;"
    filter="url(#filter1)" />
  <circle cx="100" cy="100" r="50" style="fill:blue;" filter="url(#filter1)" />
</svg>

We can access the in attribute:

js
const displacementMaps = document.querySelectorAll("feDisplacementMap");

console.log(displacementMaps[0].getAttribute("in")); // Output: "SourceGraphic"
console.log(displacementMaps[1].getAttribute("in")); // Output: "BackgroundImage"
