Fabric.js | Circle borderDashArray Property
  • Last Updated : 19 Jun, 2020

In this article, we are going to see how to make a dashed border pattern on a 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 make border dash pattern on the circle using borderDashArray property and render the Circle on the Canvas as given in the example below.

Syntax:

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

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

  • radius: It specifies the radius of circle.
  • borderDashArray: It specifies the value of dashed border of canvas circle.

Example: This example uses FabricJS to make dashed border pattern on canvas circle.
