Fabric.js | Triangle transparentCorners Property

  • Last Updated : 09 Feb, 2021

In this article, we are going to see how to set the visibility of the corner of a canvas triangle using FabricJS. The canvas means the triangle is movable and can be stretched according to requirement. Further, the triangle can be customized when it comes to initial stroke color, fill color, stroke width, or radius.
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 triangle. After this, we will initialize instances of Canvas and Triangle provided by FabricJS and set the visibility of the corner of the triangle using transparentCorners property respectively, and render the triangle on the Canvas as given in the example below.
Syntax: 
 

fabric.Triangle({
    width: number,
    height: number,
    cornerStrokeColor: string,
    transparentCorner: boolean
});

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