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 coordiante system of the element.


boolean someElement.isPointInStroke(DOMPointInit point);


A DOMPointInit interpreted as a point in the local coordinate system of the element.

Return value

A boolean indicating whether the given point is within the stroke or not.
