Fabric.js Polyline left Property

In this article, we are going to see how to set the left property of a Polyline canvas 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 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 which will contain the Polyline. After this, we will initialize instances of Canvas and Polyline provided by FabricJS and set the value of the left property of a canvas, and render the Polyline on the Canvas as given in the below example.

Syntax:

var polyline = new fabric.Polyline(Points, {  
   left: number
});  

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

  • left: It specifies the left position of an object.

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

Example:

  </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,

        x: 150, 
        y: 50 
      }, { 
        x: 200, 
        y: 10 }], { 
        stroke: 'green',  
        strokeWidth: 3,  
        cornerStyle: 'circle',  
        left: 100
      }); 
  
    // Render the polyline in canvas 
    canvas.add(polyline); 
  </script>
