Fabric.js Image type Property

Last Updated : 29 Jan, 2021

In this article, we are going to see how to set the type of canvas Image using FabricJS. The canvas Image means the Image is movable and can be stretched according to requirements. Further, the Image can be customized when it comes to initial stroke color, shape, fill color, or stroke width.

To make it 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 that will contain the Image. After this, we will initialize instances of Canvas and Image provided by FabricJS and set the minimum scale limit of the Image using type property, and render the Image on the Canvas as given in the below example.

Syntax:

var a = image.type;

Example: This example uses FabricJS to set the type property of the canvas image as shown in the below example:
