SVGFECompositeElement: k2 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 k2 read-only property of the SVGFECompositeElement interface reflects the k2 attribute of the given <feComposite> element.

Value

An SVGAnimatedNumber object.

Examples

In this example, two <feComposite> elements are defined in a filter, each with a different k2 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="140"
      x="30"
      y="10" />
    <feComposite
      in2="SourceGraphic"
      operator="arithmetic"
      k1="0.1"
      k2="0.2"
      k3="0.3"
      k4="0.4" />
  </filter>
  <circle cx="100" cy="50" r="30" filter="url(#filter1)" />
</svg>

We can access the k2 attribute:

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

console.log(composites[0].k2.baseVal); // output: 0.2
