Fabric.js Textbox inverted Property

Last Updated : 19 Jan, 2021

In this article, we are going to see how to set the inverted property of a Textbox canvas using Fabric.js. This property is useful if the object is used as a clipPath. The Textbox in Fabric.js can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, fill color, stroke width, or radius.

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 Textbox. After this, we will initialize instances of Canvas and Textbox provided by Fabric.js and set the inverted property of the Textbox using inverted property and render it on the Canvas as given in the below example.

Syntax:

fabric.Textbox('text', {
    inverted: boolean
});

Parameters: This function accepts a single parameter as mentioned above and described below:

inverted: It is a boolean value that sets the inverted property of the Textbox.

Example: This example uses Fabric.js to set the inverted property the canvas Textbox.
