The CanvasRenderingContext2D.closePath() method of the Canvas 2D API attempts to add a straight line from the current point to the start of the current sub-path. If the shape has already been closed or has only one point, this function does nothing.

This method doesn't draw anything to the canvas directly. You can render the path using the stroke() or fill() methods.

Syntax

void ctx.closePath();

Examples

Closing a triangle

This example creates the first two (diagonal) sides of a triangle using the lineTo() method. After that, the triangle's base is created with the closePath() method, which automatically connects the shape's first and last points.

HTML

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

JavaScript

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

ctx.beginPath();
ctx.moveTo(20, 150);  // Move pen to bottom-left corner
ctx.lineTo(120, 20);  // Line to top corner
ctx.lineTo(220, 150); // Line to bottom-right corner
ctx.closePath();      // Line to bottom-left corner
ctx.stroke();
