Fabric.js Path lockScalingY Property

Last Updated : 24 Jan, 2021

In this article, we are going to see how to set the lockScalingY of a Path canvas object using Fabric.js. The Path canvas object in Fabric.js is movable and can be stretched according to requirement. Further, the Path object 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 object. After this, we will initialize instances of Canvas and Path provided by Fabric.js and lock the scaling of the canvas Path in y-direction Path using lockScalingY property.

Syntax:

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

Property Value: This property holds single value as mentioned above and described below:

lockScalingY: It specifies whether the scaling of the canvas locked vertically.

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