Fabric.js Text fillRule Property

  • Last Updated : 26 Mar, 2021

In this article, we are going to see how to change the fillRule of the text canvas using Fabric.js. The canvas means the text written is movable, rotatable, resizable, and can be stretched. Further, the text itself cannot be edited like a textbox.

To make it possible, we are going to use a JavaScript library called Fabric.js. After importing the library using CDN, we will create a canvas block in the body tag that will contain our text. After this, we will initialize instances of Canvas and Text provided by FabricJS and set the fill rule of the canvas text using fillRule property.


    fillRule : String

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

  • fillRule : It specifies the rule to fill of the object. The accepted values are ‘nonzero’ and ‘evenodd’.

Below is the example that illustrates the use of fillRule property in Fabric.js:



<!DOCTYPE html> 
    <!-- Loading the FabricJS library -->
    <script src
    <div style="text-align: center;width: 400px;"
      <h1 style="color: green;"
        Fabric.js | Text fillRule Property 
    <div style="text-align: center;"
      <canvas id="canvas" width="400" height="200"
              style="border:1px solid green;"
      // Create a new instace of Canvas 
      var canvas = new fabric.Canvas("canvas"); 
      // Create a new Text instance 
      var geek = new fabric.Text('GeeksforGeeks', { 
        fill: 'lightgreen',  
        fillRule: 'nonzero' 
      // Render the text on Canvas
