Path2D: Path2D() constructor

Note: This feature is available in Web Workers.

The Path2D() constructor returns a newly instantiated Path2D object, optionally with another path as an argument (creates a copy), or optionally with a string consisting of SVG path data.

Syntax

new Path2D()
new Path2D(path)
new Path2D(d)

Parameters

path Optional: When invoked with another Path2D object, a copy of the path argument is created.
d Optional: When invoked with a string consisting of SVG path data, a new path is created from that description.

Examples

Creating and copying paths

This example creates and copies a Path2D path.

<canvas id="canvas"></canvas>

const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");

let path1 = new Path2D();
path1.rect(10, 10, 100, 100);

let path2 = new Path2D(path1);
path2.moveTo(220, 60);
path2.arc(170, 60, 50, 0, 2 * Math.PI);

ctx.stroke(path2);

This example creates a Path2D path using SVG path data. The path will move to point (M10 10) and then move horizontally 80 points to the right (h 80), then 80 points down (v 80), then 80 points to the left (h -80), and then back to the start (Z).

<canvas id="canvas"></canvas>

const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");

let p = new Path2D("M10 10 h 80 v 80 h -80 Z");
ctx.fill(p);
