Fabric.js is a javascript library that is used to work with canvas. The canvas image is one of the class of fabric.js that is used to create image instances. The canvas image means the Image is movable and can be stretched according to requirement. The cornerSize property of the image is used to change the size of the controlling corners of the canvas image.
Approach: First import the fabric.js library. After importing the library, create a canvas block in the body tag which will contain the image. After this, initialize an instance of Canvas and image class provided by Fabric.JS and change the size of the controlling corners of the canvas image using the cornerSize property of the image object.
Syntax:
fabric.Image(image, { cornerSize:Number });
Parameters: The above function takes two parameters as mentioned above and described below:
- image: This parameter takes the image.
- cornerSize: This parameter defines the size of the controlling corners of the canvas image.
Example: This example uses FabricJS to change the size of the controlling corners of the canvas image as shown in the below given example.
