SVGFECompositeElement: x property

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

It reflects the <feComposite> element’s x filter primitive attribute value. The <feComposite> SVG filter primitive combines two input images using a Porter-Duff compositing operation. 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 feComposite = document.querySelector("feComposite");
const leftPosition = feComposite.x;
console.log(leftPosition.baseVal.value); // the `x` value
