In this article, we are going to see how to set the cornerSize of a Group of the canvas using Fabric.js. The Group in Fabric.js is movable and can be stretched according to requirements. Further, the Group can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.
To make it possible we are going to use a JavaScript HTML5 canvas library called Fabric.js. After importing the library, we will create a canvas block in the body tag that will contain the Group. After this, we will initialize instances of Canvas and Group provided by Fabric.js and scale controlling corners of the Group using the cornerSize property.
Syntax:
fabric.Group([canvas1, canvas2], {
cornerSize :Number
});
Parameters: This property accepts a single parameter as mentioned above and described below:
- cornerSize : It specifies the size of the controlling corners.
Below example illustrate the use of Fabric.js Group cornerSize property in JavaScript:
Example:
HTML
<!DOCTYPE html> <html> <head> <!-- FabricJS CDN --> <script src= </script> </head> <body> <div style="text-align: center;width: 400px;"> <h1 style="color: green;"> neveropen </h1> <b> Fabric.js | Group cornerSize Property </b> </div> <div style="text-align: center;"> <canvas id="canvas" width="500" height="300" style="border:1px solid green;"> </canvas> </div> <script> // Initiate a Canvas instance var canvas = new fabric.Canvas("canvas"); // Initiate a circle instance var circle = new fabric.Circle({ radius: 100, fill: 'lightgreen', scaleY: 0.6, originX: 'center', originY: 'center' }); // Initiate a text instance var text = new fabric.Text('neveropen', { fontSize: 25, originX: 'center', originY: 'center' }); // Initiate a Group instance var group = new fabric.Group([ circle, text ], { cornerColor: 'red', cornerSize : 20 }); // Render the Group in canvas canvas.add(group); // Center the Group in canvas canvas.centerObject(group); </script> </body> </html> |
Output:
