Path.intersectsY()

The Path.intersectsY() method returns the Point object(s) where the path intersects with a given Y-value.

Signature

array|false path.intersectsY(float y)

Example

```js ({ Point, points, Path, paths, snippets, Snippet, getId, part }) => {

points.A = new Point(55, 40)
points.B = new Point(10, 70)
points.BCp2 = new Point(40, 20)
points.C = new Point(90, 60)
points.CCp1 = new Point(50, -30)
points.D = new Point(50, 80)
points.DCp1 = new Point(140, 50)

points.top = new Point(10, 58)
points.bot = new Point(130, 58)

paths.line = new Path()
.move(points.top)
.line(points.bot)
.attr("class", "lining dashed")

paths.demo = new Path() .move(points.A) .line(points.B) .curve(points.BCp2, points.CCp1, points.C) .curve(points.DCp1, points.DCp1, points.D)

for (let p of paths.demo.intersectsY(58)) { snippets[getId()] = new Snippet("notch", p) }

return part }
