Fabric.js | Circle strokeDashArray Property

  • Last Updated : 25 Jun, 2020

In this article, we are going to see how to set the stroke dash pattern of 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.
 

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 stroke color and stroke dash pattern of the circle using stroke and strokeDashArray property respectively and render the Circle on the Canvas as given in the below example.
