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

To make this possible we are going to use a JavaScript library called FabricJS. After importing the library, we will create a canvas block in the body tag which will contain the Polyline. After this, we will initialize instances of Canvas and Polyline provided by FabricJS and disable the canvas click movement property of canvas Polyline using excludeFromExport property and render the Polyline on the Canvas as given below.

Syntax:

var polyline = new fabric.Polyline(Points, { 
      excludeFromExport: boolean
}); 

Parameters: This property accepts a single parameter as mentioned above and described below:

  • excludeFromExport: When `true`, the object is not exported in OBJECT/JSON.

The below example illustrates the excludeFromExport in Fabric.js:

Example:

HTML




<!DOCTYPE html> 
<html
  
<head
    <!-- Loading the FabricJS library -->
    <script src
    </script
</head
  
<body
    <div style="text-align: center;width: 600px;"
        <h1 style="color: green;"

        <b
            Fabric.js | Polyline excludeFromExport Property 
        </b
    </div
  
    <canvas id="canvas"
            width="600"
            height="200"
            style="border:1px solid #000000;"
    </canvas
  
    <script
  
        // Initiate a Canvas instance 
        var canvas = new fabric.Canvas("canvas"); 
  
        // Initiate a Polyline instance 
        var polyline = new fabric.Polyline([ 
        { x: 200, 
            y: 10 }, 
        {x: 250, 
            y: 50 
        }, { 
            x: 250, 
            y: 180 
        }, { 
            x: 150, 
            y: 180 
        }, { 
            x: 150, 
            y: 50 
        }, { 
            x: 200, 
            y: 10 }], { 
            fill: 'green',
            excludeFromExport : 'false'
        }); 
  
        // Render the Polyline in canvas 
        canvas.add(polyline); 
    </script
</body
  
</html>
