Last Updated : 19 Jan, 2021

In this article, we are going to see how to vertically flip a Textbox canvas using FabricJS. The canvas Textbox means Textbox is movable and can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

Approach:

To make it possible, we are going to use a JavaScript library called FabricJS.
After importing the library, we will create a canvas block in the body tag which will contain the Textbox.
After this, we will initialize instances of Canvas Textbox provided by FabricJS and set the flipY property and render the Textbox on the Canvas as given in the below example.

Syntax:

fabric.Textbox('text', {
    flipY: boolean
});

Parameters: This function accepts one parameter as mentioned above and described below:

flipY: It specifies that the object flip vertically .

Example: This example uses FabricJS to flip the canvas Textbox vertically.
