HTML
html
<canvas id="canvas"></canvas>
JavaScript
js
const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");
ctx.rect(10, 10, 150, 100);
ctx.fill();
Result
Specifying a path and a fillRule
This example saves some intersecting lines to a Path2D object. The fill()
method is then used to render the object to the canvas. A hole is left unfilled in the
object's center by using the "evenodd" rule; by default (with the
"nonzero" rule), the hole would also be filled.
HTML
html
<canvas id="canvas"></canvas>
JavaScript
js
const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");
// Create path
let region = new Path2D();
region.moveTo(30, 90);
region.lineTo(110, 20);
region.lineTo(240, 130);
region.lineTo(60, 130);
region.lineTo(190, 20);
region.lineTo(270, 90);
region.closePath();
// Fill path
ctx.fillStyle = "green";
ctx.fill(region, "evenodd");
