In this article ImageData: width property

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.

Note: This feature is available in Web Workers.

The readonly ImageData.width property returns the number of pixels per row in the ImageData object.

Value

A number.

Examples

This example creates an ImageData object that is 200 pixels wide and 100 pixels tall. Thus, the width property is 200.

js

let imageData = new ImageData(200, 100);
console.log(imageData.width); // 200
