CanvasRenderingContext2D.imageSmoothingEnabled

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The CanvasRenderingContext2D.imageSmoothingEnabled property of the Canvas 2D API can be set to change if images are smoothed (true, default) or not (false). On getting the imageSmoothingEnabled property, the last value it was set to, is returned.

This property is useful for pixel-art themed games, when scaling the canvas for example. The default resizing algorithm can create blurry effects and ruins the beautiful pixels. Set this property to false in that case. See also the CSS image-rendering property.

Syntax

ctx.imageSmoothingEnabled = value;

Options

value
A Boolean indicating whether to smooth images or not.

Examples

Using the imageSmoothingEnabled property

This is just a simple code snippet using the imageSmoothingEnabled property with a scaled image.

HTML

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

JavaScript

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

var img = new Image();
img.src = 'https://mdn.mozillademos.org/files/222/Canvas_createpattern.png';
img.onload = function() {
 ctx.mozImageSmoothingEnabled = false;
 ctx.webkitImageSmoothingEnabled = false;
 ctx.msImageSmoothingEnabled = false;
 ctx.imageSmoothingEnabled = false;
 ctx.drawImage(img, 0, 0, 400, 200);
};

Edit the code below and see your changes update live in the canvas:
