Fabric.js Group includeDefaultValues Property
In this article we will covers how to set the includeDefaultValues 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 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 set the includeDefaultValues of canvas Group using the includeDefaultValues property.
Syntax:
fabric.Group([canvas1, canvas2], {
includeDefaultValues: Boolean
});
Parameters: This property accepts a single parameter as mentioned above and described below:
- includeDefaultValues: It specifies default object’s values are included in or not its serialization, When `false` values are not included in its serialization.
The below examples illustrate the use of Fabric.js Group includeDefaultValues property in JavaScript:
Example:
HTML
<!DOCTYPE html>
< html >
< head >
< script src =
</ script >
</ head >
< body >
< div style = "text-align: center;width: 400px;" >
< h1 style = "color: green;" >
GeeksforGeeks
</ h1 >

</ 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('GeeksforGeeks', {
fontSize: 25,
originX: 'center',
originY: 'center'
});
// Initiate a Group instance
var group = new fabric.Group([ circle, text ], {
cornerStyle: 'circle',
includeDefaultValues: false
});
// Render the Group in canvas
canvas.add(group);
// Center the Group in canvas
canvas.centerObject(group);
</ script >
</ body >
</ html >
