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

To make it 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 that will contain the Polyline. After this, we will initialize instances of Canvas and Polyline provided by FabricJS and set the strokeLineJoin color of the canvas triangle using the strokeLineJoin property, and render the Polyline on the Canvas as given in the below example.

Syntax:

var polyline = new fabric.Polyline(Points, {  
        strokeLineJoin: string
 });  

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

  • strokeLineJoin: Corner style of an object’s stroke (one of “bevel”, “round”, “miter”)

The below example illustrates the strokeLineJoin property in Fabric.js:

Example:

    <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,

        }, { 
            x: 150,

        }, { 
            x: 150, 
            y: 50 
        }, { 
            x: 200, 
            y: 10 }], { 
            stroke: 'green',  
            strokeWidth: 3,  
            fill: 'yellow',
            strokeLineJoin: 'round'
  
  
        }); 
  
        // Render the polyline in canvas 
        canvas.add(polyline); 
    </script
