In this article, we are going to see the noScaleCache property of a polygon canvas using FabricJS. The canvas polygon means the polygon is movable and can be stretched according to requirements. Further, the polygon 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 polygon. After this, we will initialize instances of Canvas and polygon provided by FabricJS and set the noScaleCache of canvas polygon using noScaleCache property, and render the polygon on the Canvas as given in the below example.


    { x: pixel, y: pixel },
    { x: pixel, y: pixel },
    { x: pixel, y: pixel},
    { x: pixel, y: pixel},
    { x: pixel, y: pixel }
    noScaleCache: boolean

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

  • noScaleCache: When `true`, object is cached on an additional canvas. When `false`, object is not cached unless necessary ( clipPath ) default to true.

Below examples illustrate the Fabric.JS Polygon noScaleCache in JavaScript:



<!DOCTYPE html> 
  <!-- Loading the FabricJS library -->
  <script src
  <div style="text-align: center;width: 600px;"
    <h1 style="color: green;"
        Fabric.js | Polygon noScaleCache Property 
  <canvas id="canvas" width="600" height="200"
      style="border:1px solid #000000;"
    // Initiate a Canvas instance 
    var canvas = new fabric.Canvas("canvas"); 
    // Initiate a polygon instance 
    var polygon = new fabric.Polygon([ 
        { x: 295, y: 10 }, 
        { x: 235, y: 198 }, 
        { x: 385, y: 78 }, 
        { x: 205, y: 78 }, 
        { x: 355, y: 198 }], { 
         noScaleCache: 'true' 
    // Render the polygon in canvas
