SVGFEColorMatrixElement: width 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 width read-only property of the SVGFEColorMatrixElement interface describes the horizontal size of an SVG filter primitive as a SVGAnimatedLength.

It reflects the <feColorMatrix> element's width filter primitive attribute. The <feColorMatrix> filter applies a matrix transformation on the RGB color and alpha values. The attribute is a <length> or a <percentage> relative to the width of the filter region. The default value is 100%. The property value is a length in user coordinate system units.

Value

An SVGAnimatedLength.

Example

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