How to set the tilt angle of a triangle on the x-axis using FabricJS?

In this tutorial, we will learn how to set the tilt angle on the x-axis of a triangle using FabricJS. Triangle is one of the various shapes provided by FabricJS. In order to create a triangle, we will need to create an instance of the fabric.Triangle class and add it to the canvas.

We can customize our triangle object by changing its size, adding a background color, or changing the tilt angle on the x-axis. We can achieve this using the skewX attribute.

Syntax

new fabric.Triangle({ skewX: Number }: Object )

Parameters

Options (optional Option) − This parameter is an object that provides options for additional customization of our triangle. Using this parameter, you can change the object's color, cursor, stroke width, and many other properties related to the skewX property.

Option Key

skewX< /strong> − This property accepts a number value that determines the tilt angle of the object along the x-axis.

Example 1

When the skewX attribute is not applied

< ;p> Let's look at a code example to see how our triangle object looks when the skewX property is not applied. In this case, our triangle object won't be tilted at any angle.

Example 2
Put skewX as a key and assign it a custom value.
In this example, we will see how to assign a numeric value to the skewX property. The value passed will determine the degree of tilt along the X-axis.
