How to add a linethrough to a canvas-type text using Fabric.js ?

In this article, we are going to see how to add linethrough to a canvas-like text using FabricJS. The canvas means text written is movable and can be stretched, resized and rotated according to requirements. Further, the text itself cannot be edited like a textbox.

Approach: To make it 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 text. After this, we will initialize instances of Canvas and Text provided by FabricJS and use the linethrough property to add a linethrough and render the Canvas on the Text as given in the example below.

Syntax:

fabric.Text(text, linethrough: boolean); 

Parameters: This function accepts two parameters as mentioned above and described below:

  • text: It specifies the text to be written.
  • linethrough: It specifies whether to enable or disable the linethrough text decoration, disabled by default.

Program: We can use FabricJS to add linethrough to a canvas-like text as given below.




<!DOCTYPE html>
<html>
  
<head>
    <title>
        Add linethrough to a canvas-type text
    </title>
  
    <!-- Loading the FabricJS library -->
    <script src=
    </script>
</head>
  
<body>
    <canvas id="canvas" width="600" height="200" 
            style="border:1px solid #000000;">
    </canvas>
  
    <script>
  
        // Create a new instace of Canvas
        var canvas = new fabric.Canvas("canvas");
  
        // Create a new Textbox instance
        var text = new fabric.Text('GeeksforGeeks', {
            linethrough: true
        });
  
        // Render the text on Canvas
        canvas.add(text);
    </script>
</body>
  
</html>

Output:
