SVGFECompositeElement: in1 property

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

Value

An SVGAnimatedString object.

Examples

In this example, two <feComposite> 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">
  <filter id="filter1">
    <feImage
      href="https://mdn.github.io/shared-assets/images/examples/progress-pride-flag.jpg"
      width="200" />
    <feComposite in="SourceGraphic" operator="over" />
    <feComposite in="SourceGraphic" operator="in" />
  </filter>
  <circle cx="50" cy="50" r="30" filter="url(#filter1)" />
</svg>

We can access the in attribute:

js
const composites = document.querySelectorAll("feComposite");

console.log(composites[0].in1.baseVal); // output: "SourceGraphic"
console.log(composites[1].in1.baseVal); // output: "SourceGraphic"
