Fabric.js Textbox charSpacing Property

Last Updated : 17 Jan, 2021

In this article, we are going to see how to change the character spacing of a Textbox canvas using FabricJS. The canvas Textbox means Textbox written is movable and can be stretched according to the requirement. Further, the text itself cannot be edited like a textbox.

Approach:

To make this possible, we are going to use a JavaScript library called FabricJS.
After importing the library using CDN, we will create a canvas block in the body tag which will contain our Textbox.
After this, we will initialize instances of Canvas and Textbox provided by FabricJS and use the charSpacing property to change the spacing between the characters and render the Canvas on the Textbox as given in the example below.

Syntax:

fabric.Textbox('text', {
   charSpacing: number
});

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

charSpacing: It specifies the spacing between the characters.

Example:

    <script> 
  
        // Initiate a Canvas instance  
        var canvas = new fabric.Canvas("canvas"); 
  
        // Create a new Textbox instance  
        var text = new fabric.Textbox( 
            'A Computer Science Portal', { 
            width: 500, 
            charSpacing: 20 
        }); 
  
        // Render the Textbox in canvas  
        canvas.add(text); 
        canvas.centerObject(text); 
    </script>
