Fabric.js Ellipse strokeLineJoin Property

In this article, we are going to see how to set the stroke Line Join of a canvas Ellipse using FabricJS. The canvas means Ellipse is movable and can be stretched according to requirement. Further, the Ellipse can be customized when it comes to initial stroke color, fill color, stroke width, or size.

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

Syntax:

fabric.Ellipse({
   rx: number,
   ry: number,
   fill: string,
   strokeLineJoin: string
});

Parameters: This function accepts three parameters as mentioned above and described below:

rx: It specifies the horizontal radius.
ry: It specifies the vertical radius.
fill: It specifies the color to fill the ellipse.
strokeLineJoin: It specifies the value of strokeLineJoin.

Example: This example uses FabricJS to set the value of strokeLineJoin property. The accepted values of this parameter are bevel, round, and miter.
