Fabric.js is a JavaScript library that is used to work with canvas. The canvas ActiveSelection is one of the class of Fabric.js that is used to create ActiveSelection instances. The canvas ActiveSelection means the ActiveSelection is movable and can be stretched according to requirement. In this article we will be using cornerSize property to set the size of the corners of the canvas ActiveSelection.
Approach: First import the fabric.js library. After importing the library, create a canvas block in the body tag that will contain the ActiveSelection. After this, initialize an instance of Canvas and ActiveSelection class provided by Fabric.js and use the cornerSize property to set the size of the corners.
Syntax:
fabric.ActiveSelection(ActiveSelection, {
cornerSize: number
});
Parameters: This function takes a single parameter as mentioned above and described below:
- cornerSize: This parameter takes a number value that denotes the size of the corner.
