The imageSmoothingQuality property of the CanvasRenderingContext2D interface, part of the Canvas API, lets you set the quality of image smoothing.

One of the following:

"low"

Low quality.

"medium"

Medium quality.

"high"

High quality.

This example uses the imageSmoothingQuality property with a scaled image.

HTML

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

JavaScript

const canvas = document.getElementById("canvas");
const ctx = canvas.getContext("2d");

let img = new Image();
img.src = "canvas_createpattern.png";
img.onload = () => {
  ctx.imageSmoothingQuality = "low";
  ctx.drawImage(img, 0, 0, 300, 150);
};

Result

• The interface defining this property: CanvasRenderingContext2D
• CanvasRenderingContext2D.imageSmoothingEnabled
• image-rendering
