Fabric.js Textbox absolutePositioned Property

Last Updated : 20 Jan, 2021

In this article, we are going to see how to set the absolutePositioned of a Textbox using Fabric.js. It is meaningful only when the object is used as a clipPath. 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 and set the absolute position of a canvas Textbox using absolutePositioned property.

Syntax:

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

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

absolutePositioned: It specifies whether the Textbox would be absolutely positioned.

Example: This example uses Fabric.js to set the absolute position of the Textbox.
