In this article, we are going to see how to set the flipX 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.
Approach:
- 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 horizontally flip the canvas Group using the flipX property.
Syntax:
fabric.Group([canvas1, canvas2], {
flipX: Boolean
});Parameters: This property accepts a single parameter as mentioned above and described below:
- flipX: It specifies how to horizontally flip the object. It contains a boolean value.
Below examples illustrate the use of Fabric.js Group flipX property in JavaScript:

<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 ], {
flipX: true
});
// Render the Group in canvas
canvas.add(group);
// Center the Group in canvas
canvas.centerObject(group);
</script>
</body>
