How to disable the modification of text canvas using Fabric.js ?

In this article, we are going to see how to disable the modification of text canvas using FabricJS. The canvas means text written is movable, rotatable, resizable, and can be stretched. But in this article, we will disable the modification. 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 selectable property to disable the modification and render the Canvas on the Text as given in the example below.

Syntax:

 fabric.Text(text, selectable: boolean); 

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

  • text: It specifies the text to be written.
  • selectable: It specifies whether to allow modification or not, true by default.

Program: We can use FabricJS to disable the modification of canvas-like text as given below.
