Fabric.js Textbox cornerDashArray Property

  • Last Updated : 20 Jan, 2021

In this article, we are going to see how to set the dash pattern 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 this 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, set a dash pattern of controlling corners of the canvas Textbox using cornerDashArray property, and render the Textbox on the Canvas as given in the below example.
