SVGFEConvolveMatrixElement: 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 SVGFEConvolveMatrixElement interface describes the horizontal coordinate of the position of an SVG filter primitive as a SVGAnimatedLength.

It reflects the <feConvolveMatrix> element's x filter primitive attribute value. The <feConvolveMatrix> filter applies a matrix convolution effect, combining pixels in the input image with neighboring pixels to produce a convolution effect such as blurring, edge detection, sharpening, embossing or beveling. 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

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