Fabric.js Text strokeLineCap Property

Last Updated : 31 May, 2021

In this article, we are going to see how to change the strokeLineCap of the text canvas using Fabric.js. The canvas means the text written is movable, rotatable, resizable, and can be stretched. Further, the text itself cannot be edited like a textbox.

Approach:

To make it possible, we are going to use a JavaScript library called Fabric.js.
After importing the library using CDN, we will create a canvas block in the body tag that will contain our text.
After this, we will initialize instances of Canvas and Text provided by FabricJS and set the strokeLineCap color of the canvas text using strokeLineCap property.

Syntax:

fabric.Text(text,
    strokeLineCap: String
);

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

strokeLineCap : It specifies whether to set the stroke line cap or not.

Below is the example that illustrates the use of strokeLineCap property in Fabric.js:
