Fabric.js | Circle width Property
  • Last Updated : 13 May, 2020

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

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 circle. After this, we will initialize instances of Canvas and Circle provided by FabricJS and set the width of the circle using width property respectively, and render the Circle on the Canvas as given below example.

Syntax:

fabric.Circle({
    radius: number,
    width: number
}); 

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

  • radius: It specifies the radius of circle.
  • width: It specifies the width.

Example: This example uses FabricJS to set the width of a canvas circle.
