Fabric.js | Rect visible Property
  • Last Updated : 27 May, 2020

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

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 rectangle. After this, we will initialize instances of Canvas and Rect provided by FabricJS and set the visibility of the canvas rectangle using visible property and render the Rect on the Canvas as given in the example below.

Syntax:

fabric.Rect({
    width: number,
    height: number,
    visible: boolean
}); 

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

  • width: It specifies the horizontal length.
  • height: It specifies the vertical length.
  • visible: It specifies the visibility of the object.

Example: This example uses FabricJS to set the visibility of the canvas rectangle.

    <script>
        // Initiate a Canvas instance
        var canvas = new fabric.Canvas("canvas");
  
        // Initiate a Rect instance
        var rect = new fabric.Rect({
            width: 200,
            height: 100,
            visible: false
        });
  
        // Render the rectangle in canvas
        canvas.add(rect);
    </script>
</body>

Output:
