How to create a canvas image using Fabric.js ?

Last Updated : 01 Nov, 2022

In this article, we are going to see how to create a canvas-like image in JavaScript. The canvas like image means the image is movable and can be resized according to requirement. Approach: To make this possible we are going to use a JavaScript library called FabricJS. After importing the library, we will create a canvas block in the body tag which will contain our image. Further, we will create an img element which contains the image to be added inside the canvas and set the style attribute to display:none; because we don’t want the image to be visible outside the canvas. After this, we will initialize instances of Canvas and Image provided by FabricJS and render the Image on the Canvas as given in the example below. Syntax:

 fabric.Image( image_element );

Example: This example uses FabricJS to create simple editable canvas image.
