Fabric.js Path lockScalingFlip Property

Last Updated : 24 Jan, 2021

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

Syntax:

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

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

lockScalingFlip: It specifies whether to lock flipping by scaling or not.

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