Fabric.js Textbox originY Property

  • Last Updated : 22 Jan, 2021
Geek Week

In this article, we are going to see how to set the vertical origin of the transformation of a canvas Textbox using Fabric.js. The Textbox in Fabric.js 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.

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

Syntax:

fabric.Textbox('text', {
   originY: string
});

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

  • originY: It specifies the vertical transformation of the Textbox.

Example: This example uses Fabric.js to set the vertical transformation of a Textbox.

            originY: "center"
        });
