The preserveAspectRatio
read-only property of the SVGMarkerElement
interface returns an SVGAnimatedPreserveAspectRatio
object containing the value of the preserveAspectRatio
attribute of the <marker>
.
SVGMarkerElement.preserveAspectRatio
Value

Examples
This example demonstrates how to return the numeric constants for align
and meetOrSlice
which relate to the values set for the preserveAspectRatio
attribute of <marker>
.
<svg id="svg" viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg"> <defs> <marker id="arrow" viewBox="0 0 10 10" refX="5" refY="5" preserveAspectRatio="xMidYMid meet" markerWidth="6" markerHeight="6" orient="auto-start-reverse"> <path d="M 0 0 L 10 5 L 0 10 z" /> </marker> </defs> </svg>
let marker = document.getElementById("arrow"); console.log(marker.preserveAspectRatio.baseVal.align); // 6 console.log(marker.preserveAspectRatio.baseVal.meetOrSlice); // 1
