Fabric.js Path lockMovementY Property

Last Updated : 25 Jan, 2021

In this article, we are going to see how to set the lockMovementY of a Path using Fabric.js. The Path in Fabric.js is movable and can be stretched according to requirements. Further, the Path 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 Path. After this, we will initialize instances of Canvas and Path provided by Fabric.js and lock the vertical movement of the canvas Path using lockMovementY property.

Syntax:

fabric.Path('path', {
   lockMovementY: Boolean
});

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

lockMovementY: It specifies whether to lock vertical movement of canvas.

Below example illustrates the use of Fabric.js Path lockMovementY property in JavaScript:
