How to lock the horizontal movement of a canvas text using Fabric.js ?

Last Updated : 27 Aug, 2021

In this article, we are going to see how to lock the horizontal movement of a canvas-like text using FabricJS. The canvas means text written is movable, rotatable, resizable and can be stretched according to requirement but we will lock the horizontal movement so that it cannot be moved left or right. 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 lockMovementX property to lock the horizontal movement and render the Canvas on the Text as given in the example below.
Syntax:

 fabric.Text(text, lockMovementX: boolean);

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

text: It specifies the text to be written.
lockMovementX: It specifies whether to enable or disable the horizontal movement lock, disabled by default.

Program: We can use FabricJS to lock the horizontal movement of canvas-like text as given below.
