HTML canvas rotate() Method

Last Updated : 27 Apr, 2023

The HTML canvas rotate() Method is used to rotate the drawing by a given angle. Note that the rotation will only work on the canvas that was made after the rotation was done.

Syntax:

context.rotate(angle)

Parameter Values:

angle: It stores the rotation angle in radians. If the angle is given in the form of a degree then it converts into a radian by using the formula degree*Math.PI/180.

Example 1:

html

<!DOCTYPE html> 
<html> 

<head> 
    <title> 
        HTML canvas rotate() Method
    </title> 
</head> 

<body> 
<center>
<h1 style="color:green">GeeksforGeeks</h1>
    <canvas id="GFG" width="500"
            height="300" style="border:2px solid gray;"> 
</canvas> 

    <script> 
        var geeks = document.getElementById("GFG"); 
        var context = geeks.getContext("2d"); 
        context.rect(100, 100, 150, 100);//actual rectangle
        context.stroke(); 
        
        context.rotate((-20) * Math.PI / 180);
        context.rect(100, 100, 150, 100);//rotate rectangle
        context.stroke();
    </script> 
</center>
</body>
