How to set the angle of skew on x-axis of Rectangle using FabricJS?
<p>In this tutorial, we are going to learn how to set the angle of skew on the x-axis of a Rectangle using FabricJS. Rectangle is one of the various shapes provided by FabricJS. In order to create a rectangle, we will have to create an instance of <em>fabric.Rect</em> class and add it to the canvas.</p><p>Our rectangle object can be customized in various ways like changing its dimensions, adding a background color or by changing the angle of skew on the x-axis. We can do this by using the <em>skewX</em> property.</p><h2>Syntax</h2><pre class="result notranslate">new fabric.Rect({ skewX : Number }: Object)</pre><h2>Parameters</h2><ul class="list"><li><p><strong>Options (optional)</strong> − This parameter is an <em>Object</em> which provides additional customizations to our rectangle. Using this parameter, properties such as colour, cursor, stroke width and a lot of other properties can be changed related to the object of which <em>skewX </em>is a property.</p></li></ul><h2>Options keys</h2><ul class="list"><li><p><strong><em>skewX</em></strong> − This property accepts a <strong>Number</strong> which determines the angle of skew on X-axis of an object.</p></li></ul><h2>Example 1</h2><p><strong>When the skewX property is not applied</strong></p><p>Let’s see a code example to understand how our rectangle object appears when the <em>skewX</em> property is not applied. In this case, there will be no skew by any angle in our rectangle object.</p><pre class="demo-code notranslate language-javascript" data-lang="javascript"><!DOCTYPE html> <html> <head> <!-- Adding the Fabric JS Library--> <script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script> </head> <body> <h2>When the skewX property is not applied</h2> <p>You can see there is no skew by any angle on the rectangle by default</p> <canvas id="canvas"></canvas> <script> // Initiate a canvas instance var canvas = new fabric.Canvas("canvas"); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250); // Initiate a rectangle object var rect = new fabric.Rect({ left: 105, top: 70, width: 170, height: 70, fill: "#8f9779", stroke: "#8fbc8f", strokeWidth: 9, }); // Add it to the canvas canvas.add(rect); </script> </body> </html></pre><h2>Example 2</h2><p><strong>Passing skewX as key and assigning a custom value to it.</strong></p><p>In this example, we will see how we can assign a numerical value to the skewX property. The value that is being passed will determine the skew along the X-axis.</p><pre class="demo-code notranslate language-javascript" data-lang="javascript"><!DOCTYPE html> <html> <head> <!-- Adding the Fabric JS Library--> <script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script> </head> <body> <h2>Passing skewX as key and assigning a custom value to it</h2> <p>You can see the rectangle has skewed at a 50 degree angle on X-axis</p> <canvas id="canvas"></canvas> <script> // Initiate a canvas instance var canvas = new fabric.Canvas("canvas"); canvas.setWidth(document.body.scrollWidth); canvas.setHeight(250); // Initiate a rectangle object var rect = new fabric.Rect({ left: 105, top: 70, width: 170, height: 70, fill: "#8f9779", stroke: "#8fbc8f", strokeWidth: 9, skewX: 50, }); // Add it to the canvas canvas.add(rect); </script> </body> </html></pre>
