Fabric.js Group lockMovementX Property

  • Last Updated : 29 Jan, 2021

The following article covers how to set the lockMovementX of a Group of the canvas using Fabric.js. The Group in Fabric.js is movable and can be stretched according to requirements. Further, the Group 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 that will contain the Group. After this, we will initialize instances of Canvas and Group provided by Fabric.js and see if the option set to true will lock the horizontal movement in the canvas Group using the lockMovementX property.

Syntax:

fabric.Group([canvas1, canvas2], {
   lockMovementX: Boolean
});

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

  • lockMovementX: It specifies if the option set to true will lock the horizontal movement. It contains a boolean value

The below examples illustrate the use of Fabric.js Group lockMovementX property in JavaScript:
