SVGFEGaussianBlurElement: 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 SVGFEGaussianBlurElement interface reflects the in attribute of the given <feGaussianBlur> element.

Value

An SVGAnimatedString object.

Examples

In this example, two <feGaussianBlur> 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="gaussian-blur-filter">
      <!-- Gaussian blur applied to the SourceGraphic -->
      <feGaussianBlur
        in="SourceGraphic"
        stdDeviation="5"
        result="blurred-source" />
      <!-- Gaussian blur applied to the BackgroundImage -->
      <feGaussianBlur
        in="BackgroundImage"
        stdDeviation="10"
        result="blurred-background" />
    </filter>
  </defs>

  <!-- Rectangle with SourceGraphic blur effect -->
  <rect
    x="20"
    y="20"
    width="100"
    height="100"
    style="fill:rebeccapurple;"
    filter="url(#gaussian-blur-filter)" />

  <!-- Circle with BackgroundImage blur effect -->
  <circle
    cx="150"
    cy="100"
    r="50"
    style="fill:hotpink;"
    filter="url(#gaussian-blur-filter)" />
</svg>

We can access the in attribute:

js
// Get all feGaussianBlur elements
const gaussianBlurs = document.querySelectorAll("feGaussianBlur");

// Access the 'in' attribute values
console.log(gaussianBlurs[0].in1.baseVal); // Output: "SourceGraphic"
console.log(gaussianBlurs[1].in1.baseVal); // Output: "BackgroundImage"
