Fabric.js Textbox cornerStyle Property

Last Updated : 16 Feb, 2021

In this article, we are going to see how to set the style of controlling corners of the canvas Textbox using Fabric.js. The Textbox in Fabric.js is movable and can be stretched according to requirements. Further, the Textbox 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 which will contain the Textbox. After this, we will initialize instances of Canvas and Textbox, set the style of controlling corners of canvas Textbox using cornerStyle property, and render the Textbox on the Canvas as given in the below example.

Syntax:

fabric.Textbox('text', {
    cornerStyle: string
});

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

cornerStyle: It specifies the style of the controlling corners. The accepted values of this parameter are rect , square, and circle only.

Example: This example uses Fabric.js to set the style of controlling corners of the Textbox as given below. You have to click on the object to see the style of controlling corners.
