Fabric.js Textbox originX Property

Last Updated : 22 Jan, 2021

In this article, we are going to see how to set the horizontal origin of a Textbox canvas object using FabricJS. The canvas Textbox means the 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 HTML5 canvas library called FabricJS.
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 FabricJS and set the horizontal transformation of the Textbox using originX property and render the Textbox on the Canvas as given in the example below.

Syntax:

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

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

originX: It specifies the horizontal transformation of a canvas textbox.

Example: This example uses FabricJS to set the horizontal transformation of canvas textbox.
