In this article, we are going to see how to set the evented property of the canvas Circle using Fabric.js. The Circle in Fabric.js is movable and can be stretched according to the requirement. Further, the Circle can be customized when it comes to initial stroke color, fill color, stroke width, or size.
To make this possible we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag which will contain the Circle. After this, we will initialize instances of Canvas and Circle provided by Fabric.js, disable the canvas click movement property of the Circle using evented property, and render the circle on the Canvas as given below.
Syntax:
fabric.Circle({
radius: number,
evented: boolean
});
Parameters: This function accepts two parameters as mentioned above and described below:
- radius: It specifies the radius of the Circle.
- evented: It specifies whether to enable or disable the target of events.
Example:
HTML
<html> <head> <!-- FabricJS CDN --> <script src= </script> </head> <body> <h1 style="color: green;"> neveropen </h1> <h3> Fabric.js Circle evented Property </h3> <canvas id="canvas" width="600" height="300" style="border:1px solid #000000"> </canvas> <script> // Initiate a Canvas instance var canvas = new fabric.Canvas("canvas"); // Initiate a Circle instance var circle = new fabric.Circle({ radius: 100, fill: '', stroke: 'green', strokeWidth: 3, evented: true }); // Render the circle in canvas canvas.add(circle); canvas.centerObject(circle); </script> </body> </html> |
Output:
