In this article, we are going to see how to change the controlling corners color 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 that will contain our circle. After this, we will initialize instances of Canvas and Circle provided by FabricJS and change the controlling corners color of the circle using cornerColor property and render the Circle on the Canvas as given in the below example.
Syntax:
fabric.Circle({
radius: number,
cornerColor: string
}); Parameters: This function accept two parameters as mentioned above and described below:
- radius: This parameter holds the radius of circle.
- cornerColor: This parameter specifies the color of the controlling corners.
Example: This example uses FabricJS to change the controlling corners color of a canvas circle. Note that you have to click on the object to see the color.
