Fabric.js Text touchCornerSize Property

  • Last Updated : 19 Mar, 2021

In this article, we are going to see how to change the touchCornerSize 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 touchCornerSize color of the canvas text using touchCornerSize property.

Syntax:

 fabric.Text(text,
    touchCornerSize :Number
 ); 

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

  • touchCornerSize: Size of object’s controlling corners when touch interaction is detected.

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



Example:

HTML




<!DOCTYPE html> 
<html
  
  <head
    <!-- Loading the FabricJS library -->
    <script src
    </script
  </head
  
  <body
    <div style="text-align: center;width: 400px;"
      <h1 style="color: green;"
        GeeksforGeeks 
      </h1>
      <b
        Fabric.js | Text touchCornerSize Property 
      </b
    </div
  
    <div style="text-align: center;"
      <canvas id="canvas" width="400" height="200"
              style="border:1px solid green;"
      </canvas
    </div
  
    <script
      // Create a new instace of Canvas 
      var canvas = new fabric.Canvas("canvas"); 
  
      // Create a new Text instance 
      var geek = new fabric.Text('GeeksforGeeks', {  
        touchCornerSize: 2
      });
  
      // Render the text on Canvas 
      canvas.add(geek); 
      canvas.centerObject(geek);
    </script
  </body
  
</html>

Output:
