{{APIRef("SVG")}}
The x read-only property of the {{domxref("SVGFETileElement")}} interface describes the horizontal coordinate of the position of an SVG filter primitive as an {{domxref("SVGAnimatedLength")}}.
It reflects the {{SVGAttr("x")}} attribute of the {{SVGElement("feTile")}} element, which fills a target rectangle with a repeated, tiled pattern of an input image. 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.
An {{domxref("SVGAnimatedLength")}}.
const feTile = document.querySelector("feTile");
const leftPosition = feTile.x;
console.log(leftPosition.baseVal.value); // the `x` value
