Fabric.js Textbox lockSkewingX Property

Last Updated : 20 Jan, 2021

In this article, we are going to see how to lock horizontally skewing of a canvas Textbox using FabricJS. The canvas Textbox means the Textbox is movable and can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

Approach:

To make it possible we are going to use a JavaScript library called FabricJS.
After importing the library, we will create a canvas block in the body tag that will contain the Textbox.
After this, we will initialize instances of Canvas and Textbox provided by FabricJS and set the lockSkewingX of canvas Textbox using lockSkewingX property and render the Textbox on the Canvas as given in the below example.

Syntax:

fabric.Textbox('text', {
   lockSkewingX: boolean
});

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

lockSkewingX: It specifies whether to lock horizontally skewing of a triangle canvas or not.

Example: This example uses FabricJS to set the horizontally skewing of a canvas textbox as given below.
