SVGFEColorMatrixElement: x 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 x read-only property of the SVGFEColorMatrixElement interface describes the horizontal coordinate of the position of an SVG filter primitive as a SVGAnimatedLength.

It reflects the <feColorMatrix> element's x filter primitive attribute value. The <feColorMatrix> filter applies a matrix transformation on the RGB color and alpha values. The attribute is a <length> or <percentage>. The <coordinate> is a length in the user coordinate system that is the given distance from the origin of the user coordinate system along the x-axis. If the x attribute is a percent value, the property value is relative to the width of the filter region in user coordinate system units. The default value is 0.

Value

An SVGAnimatedLength.

Example

const feColorMatrix = document.querySelector("feColorMatrix");
const leftPosition = feColorMatrix.x;
console.log(leftPosition.baseVal.value); // the `x` value
