How to change the font family of Text using FabricJS?


In this tutorial, we are going to learn about how to change the font family of Text object using FabricJS. We can display text on canvas by adding an instance of fabric.Text. Not only does it allow us to move, scale and change the dimensions of the text but it also provides additional functionality like text alignment, text decoration, line height which can be obtained by the properties textAlign, underline and lineHeight respectively. We can change the font family by using the fontFamily property.

Syntax

new fabric.Text(text: String, { fontFamily: String }: Object)

Parameters

  • text − This parameter accepts a String which is the text string that we want to display.

  • options (optional) − This parameter is an Object which provides additional customizations to our text. Using this parameter colour, cursor, border width and a lot of other properties can be changed related to the object of which fontFamily is a property.

Options Keys

  • fontFamily − This property accepts a String that allows us to control the font family of text. The default font family is Times New Roman.

Example 1

Default appearance of text object

Let’s see a code example to see how our text object looks like when fontFamily property is not used. The text will appear in Times New Roman since no value has been specified.

<!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>Default appearance of text object</h2> <p>You can see that the font family is Times New Roman</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 text object var text = new fabric.Text("Add sample text here", { left: 50, top: 70, }); // Add it to the canvas canvas.add(text); </script> </body> </html>

Example 2

Passing the fontFamily property as key with the value as “Helvetica”

In this example, we are passing the fontFamily property as key, with a value as “Helvetica”.

<!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 the fontFamily property as key with the value as “Helvetica”</h2> <p>You can see that the font family is Helvetica</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 text object var text = new fabric.Text("Add sample text here", { left: 50, top: 70, fontFamily: "Helvetica", }); // Add it to the canvas canvas.add(text); </script> </body> </html>
