How to change background color of canvas-type text using Fabric.js ?
  • Last Updated : 29 Apr, 2020

In this article, we are going to see how to change the background color of the canvas-like text using FabricJS. The canvas means text written is movable, rotatable, resizable, and can be stretched. But in this article, we will change the background color. Further, the text itself cannot be edited like a textbox.

Approach: To make it possible, we are going to use a JavaScript library called FabricJS. After importing the library using CDN, we will create a canvas block in the body tag which will contain our text. After this, we will initialize instances of Canvas and Text provided by FabricJS and use the textBackgroundColor property to change the background color and render the Canvas on the Text as given in the example below.

Syntax:

 fabric.text(text :string, textBackgroundColor:string); 

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

  • text: It specifies the text.
  • textBackgroundColor: It specifies the background color.

Program: This example uses FabricJS to change background color of canvas-like text as given below.
