Fabric.js Image centeredScaling Property
  • Last Updated : 29 Jan, 2021

Fabric.js is a JavaScript library that is used to work with canvas. The canvas Image is one of the classes of Fabric.js that is used to create Image instances. The Image in Fabric.js is movable and can be stretched according to requirement. In this article, we will be using the centeredScaling property to enable centered scaling in a canvas Image.

Approach: First import the Fabric.js library. After importing the library, create a canvas block in the body tag which will contain the Image. After this, initialize an instance of Canvas and Image class provided by Fabric.js, set the centeredScaling property to enable the centered scaling and render the Image on the canvas.

Syntax:

fabric.Image(image, {
  centeredScaling: boolean
});

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

  • centeredScaling: This parameter defines whether to enable or disable centered scaling.

Example: This example uses Fabric.js to set the centeredScaling property of the canvas Image as shown in the below example:

    </canvas
    <img src
        width="100" height="100" id="my-image"
        style="display: none;"
    <br>
    <script
        // Creating the instance of canvas object 
        var canvas =
            new fabric.Canvas("canvas"); 
  
        // Getting the image 
        var img =
            document.getElementById('my-image'); 
  
        // Creating the image instance 
        var geeks = new fabric.Image(img, {
            centeredScaling : true
        }); 
  
        canvas.add(geeks);
