| utils.pointOnLine() |
The utils.pointOnLine() function returns true if the point check lies on a
line segment from point from to point to.
Signature
bool utils.pointOnLine(
Point from,
Point to,
Point check,
float precision = 1e6
)
The fourth parameter controls the precision. See pointOnBeam.
Example
```js ({ Point, points, Path, paths, Snippet, snippets, getId, utils, part }) => {points.from1 = new Point(10, 10) points.to1 = new Point(90, 60) points.from2 = new Point(10, 30) points.to2 = new Point(90, 80) points.b1 = new Point(170, 110) points.b2 = new Point(170, 130)
const scatter = [] for (let i = 1; i < 36; i++) { for (let j = 1; j < 27; j++) { scatter.push(new Point(i * 10, j * 10)) } } let snippet for (let point of scatter) { if (utils.pointOnLine(points.from1, points.to1, point)) snippet = "notch" else snippet = "bnotch" snippets[getId()] = new Snippet(snippet, point) if (utils.pointOnLine(points.from2, points.to2, point, 0.01)) { snippet = "notch" } else snippet = "bnotch" snippets[getId()] = new Snippet(snippet, point) } paths.line1 = new Path() .move(points.from1) .line(points.to1) .addClass("fabric stroke-lg") paths.lne1 = new Path() .move(points.to1) .line(points.b1) .addClass("fabric dashed") paths.line2 = new Path() .move(points.from2) .line(points.to2) .addClass("fabric stroke-lg") paths.lne2 = new Path() .move(points.to2) .line(points.b2) .addClass("fabric dashed")
return part }
