Fabric.js Circle flipX Property
  • Last Updated : 25 Jan, 2021

In this article, we are going to see how to horizontally flip a Circle using Fabric.js. The Circle in Fabric.js is movable and can be stretched according to the requirement. Further, the Circle can be customized when it comes to initial stroke color, fill color, stroke width, or size.

Approach: 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 which will contain the Circle. After this, we will initialize instances of Canvas and circle provided by Fabric.js, set whether to horizontally flip the Circle using the flipX property and render the Circle on the Canvas as given in the below example.

Syntax:

fabric.Circle({
   radius: number,
   flipX: boolean
});

Parameters: This function accepts two parameters as mentioned above and described below:

  • radius: It specifies the radius of the Circle.
  • flipX: It specifies whether to flip the object horizontally.

Example: This example uses Fabric.js to flip the canvas Circle horizontally.

            fill: '',
            stroke: 'green',
            strokeWidth: 3,
            flipY: true
        });
