How to add default horizontal scaling to a canvas-type text with JavaScript?
  • Last Updated : 10 May, 2020

In this article, we are going to see how to add default horizontal scaling to a canvas-like text in JavaScript. By canvas-like, we mean text written is movable, rotatable, resizable and can be stretched. But in this article, we will add default horizontal scaling. Further, the text itself cannot be edited like a textbox.

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 text. After this, we will initialize instances of Canvas and Text provided by FabricJS and use the scaleX property to add default horizontal scaling and render the Canvas on the Text as given in the example below.

Syntax:

 fabric.Text(text, scaleX: number); 

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

  • text: It specifies the text to be written.
  • scaleX: It specifies the default horizontal scaling.

Example: We can use FabricJS to add default horizontal scaling to a canvas-like text as given below.




<!DOCTYPE html>
<html>
  
<head>
    <title>
        Add default horizontal scaling to a canvas-type text with JavaScript
    </title>
  
    <!-- Loading the FabricJS library -->
    <script src=
    </script>
    <style>
        h1 {
            color: green;
        }
    </style>
</head>
  
<body>
    <center>
        <h1>GeeksforGeeks</h1>
        <b>lock scaling flip of a canvas-type text</b>
        <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 Text instance
            var text = new fabric.Text('GeeksforGeeks', {
            scaleX: 2
            });
  
            // Render the text on Canvas
            canvas.add(text);
        </script>
    </center>
</body>
  
</html>                    

Output:
