CanvasRenderingContext2D: lineTo() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The CanvasRenderingContext2D method lineTo(), part of the Canvas 2D API, adds a straight line to the current sub-path by connecting the sub-path's last point to the specified (x, y) coordinates.

Like other methods that modify the current path, this method does not directly render anything. To draw the path onto a canvas, you can use the fill() or stroke() methods.

Syntax

js
lineTo(x, y) 

Parameters

x

The x-axis coordinate of the line's end point.

y

The y-axis coordinate of the line's end point.

Return value

None (undefined).

Examples

Drawing a straight line

This example draws a straight line using the lineTo() method.

HTML

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

JavaScript

The line begins at (30, 50) and ends at (150, 100).

js
const canvas = document.getElementById("canvas"); const ctx = canvas.getContext("2d"); ctx.beginPath(); // Start a new path ctx.moveTo(30, 50); // Move the pen to (30, 50) ctx.lineTo(150, 100); // Draw a line to (150, 100) ctx.stroke(); // Render the path 

Result

Drawing connected lines

Each call of lineTo() (and similar methods) automatically adds to the current sub-path, which means that all the lines will all be stroked or filled together. This example draws a letter 'M' with a single contiguous line.

HTML

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

JavaScript

js
const canvas = document.getElementById("canvas"); const ctx = canvas.getContext("2d"); ctx.moveTo(90, 130); ctx.lineTo(95, 25); ctx.lineTo(150, 80); ctx.lineTo(205, 25); ctx.lineTo(210, 130); ctx.lineWidth = 15; ctx.stroke();
