How to add default vertical scaling to a text canvas using Fabric.js ?

  • Last Updated : 27 Apr, 2020

In this article, we are going to see how to add default vertical scaling to a text canvas using FabricJS. The canvas means text written is movable, rotatable, resizable and can be stretched. But in this article, we will add default vertical scaling. Further, the text itself cannot be edited like a textbox.

Approach: To make it possible, we are going to use a JavaScript library called FabricJS. After importing the library using CDN, we will create a canvas block in the body tag which will contain our text. After this, we will initialize instances of Canvas and Text provided by FabricJS and use the scaleY property to add default vertical scaling and render the Canvas on the Text as given in the example below.
