SVGFEColorMatrixElement: in1 property

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 SVGFEColorMatrixElement interface reflects the in attribute of the given element.

Value

An SVGAnimatedString object.

Examples

In this example, two <feColorMatrix> 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="color-matrix-filter">
    <feColorMatrix
      in="SourceGraphic"
      type="matrix"
      values="1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0" />
    <feColorMatrix
      in="BackgroundImage"
      type="matrix"
      values="0.5 0 0 0 0 0 0.5 0 0 0 0 0 0.5 0 0 0 0 0 1 0" />
  </filter>
  <rect
    x="20"
    y="20"
    width="100"
    height="100"
    style="fill:red;"
    filter="url(#color-matrix-filter)" />
  <circle
    cx="100"
    cy="100"
    r="50"
    style="fill:blue;"
    filter="url(#color-matrix-filter)" />
</svg>

We can access the in attribute:

js
const colorMatrices = document.querySelectorAll("feColorMatrix");

console.log(colorMatrices[0].in1.baseVal); // Output: "SourceGraphic"
console.log(colorMatrices[1].in1.baseVal); // Output: "BackgroundImage"
