How to vertically flip a text canvas using Fabric.js ?

Last Updated : 13 Sep, 2021

In this article, we are going to see how to vertically flip a canvas text using FabricJS. The canvas means text written is movable and can be stretched according to requirement. Further, the text itself cannot be edited like a textbox.
Approach: To make this 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 flipY property to vertically flip the text and render the Canvas on the Text as given in the example below.
Syntax:

fabric.Text(text, flipY: Boolean);

Parameters: This function accepts two parameters as mentioned above and described below:

text: It specifies the text to be written.
flipY: It specifies whether to flip the text vertically.

Program: This example uses FabricJS to vertically flip a canvas text.
