How to add vertical skew to a canvas-type text using Fabric.js?
To add vertical skew to a canvas-type text using Fabric.js, we first need to create a text object. Next, we can use the "setSkewY" method and pass in the desired degree of skew as a parameter. Finally, we can call the "renderAll" method to update the canvas with the skewed text. Let us first understand what Fabric.js is.
What is Fabric.js?
Fabric.js is a JavaScript library that allows you to create and manipulate canvas elements in a web page.
It provides a variety of objects such as text, images, shapes, and more that can be added to a canvas, as well as methods for manipulating and styling these objects.
It also includes support for events, animation, and object-oriented programming, making it a powerful tool for creating interactive and dynamic canvas-based applications.
Fabric.js is an open-source library and is actively developed and maintained by a community of developers.
It is widely used in web development, especially in creating interactive graphics, diagrams, animations, and games.
Approach
Create a new canvas element in your HTML file and give it an id (e.g. "myCanvas").
Add fabric.js script in your HTML head tag −
<script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/4.2.0/fabric.min.js"></script>
In your JavaScript file, create a new Fabric.js canvas object by using the id of the canvas element −
var canvas = new fabric.Canvas('myCanvas');
Create a new text object by using the fabric.Text constructor −
var text = new fabric.Text('Hello, World!', {
left: 100,
top: 100,
fontSize: 24
});
Add the text object to the canvas −
canvas.add(text);
To add vertical skew to the text, you can use the skewY property of the text object. This property takes a value in degrees, where positive values will skew the text to the right, and negative values will skew the text to the left −
text.skewY = 10;
Finally, call the renderAll() method of the canvas to update the canvas with the new skew value −
canvas.renderAll();
Your text should now be skewed vertically on the canvas. You can adjust the skew value as needed to achieve the desired effect.
Example
Here is a full working example of adding vertical skew to a canvas text using Fabric.js −
<!DOCTYPE html>
<html>
<head>
<title>Vertical Skew</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/4.2.0/fabric.min.js"></script>
</head>
<body>
<div>
<canvas id="myCanvas"></canvas>
</div>
<script>
// Create a new canvas object
var canvas = new fabric.Canvas('myCanvas');
// Create a new text object
var text = new fabric.Text('Hello, World!', {
left: 100,
top: 100,
fontSize: 24
});
// Add the text object to the canvas
canvas.add(text);
// Set the skewY property of the text object to 10 degrees
text.skewY = 10;
// Render the canvas
canvas.renderAll();
</script>
</body>
</html>
