Fabric.js Canvas backgroundColor Property

Last Updated : 30 Jul, 2021

In this article, we are going to see how to set the background color of a Canvas in Fabric.js using the backgroundColor property. The Canvas in Fabric.js is used as a wrapper over the native canvas object provided by HTML. It provides high-level access to the underlying canvas allowing it to have an object model, allow parsing for SVG files, and allowing the canvas to be interacted with in an intuitive manner.

Approach: To make it possible, we are going to use a JavaScript library called Fabric.js. After importing the library, we will create the canvas block in the body tag. After this, we will initialize an instance of the Canvas object provided by Fabric.js and change the background color of the Canvas using the backgroundColor property.

Syntax:

fabric.Canvas(canvasElement, {
    backgroundColor: String
});

Parameters: This property accepts a single parameter as mentioned above and described below:

backgroundColor: It is a string that specifies the background color of the Canvas.

The below example illustrates the use of Fabric.js Canvas backgroundColor property in JavaScript:
