The SVGGeometryElement.isPointInStroke()
method determines whether a given point is within the stroke shape of an element. Normal hit testing rules apply; the value of the pointer-events
property on the element determines whether a point is considered to be within the stroke. The point
argument is interpreted as a point in the local coordinate system of the element.

<svg viewBox="0 0 100 100" width="150" height="150" xmlns="http://www.w3.org/2000/svg"> <circle id="circle" cx="50" cy="50" r="45" fill="white" stroke="black" stroke-width="10"/> <circle cx="10" cy="10" r="5" fill="seagreen"/> <circle cx="40" cy="30" r="5" fill="seagreen"/> <circle cx="83" cy="17" r="5" fill="seagreen"/> </svg>
JavaScript
var circle = document.getElementById('circle'); // Point not in circle console.log('Point at 10,10:', circle.isPointInStroke(new DOMPoint(10, 10))); // Point in circle but not stroke console.log('Point at 40,30:', circle.isPointInStroke(new DOMPoint(40, 30))); // Point in circle stroke console.log('Point at 83,17:', circle.isPointInStroke(new DOMPoint(83, 17)));
