Fabric.js | Triangle borderColor Property

  • Last Updated : 02 Feb, 2021

In this article, we are going to see how to draw a bordered colored canvas Triangle using FabricJS. The canvas triangle 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, height, width, fill, 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 triangle. After this, we will initialize instances of Canvas and triangle provided by FabricJS and enable the borderColor of canvas triangle using borderColor property and render the triangle on the Canvas as given below.

Syntax:  

fabric.Triangle({
    width: number,
    height: number,
    borderColor: 'purple'
});

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

  • width: It specifies the width of triangle.
  • height: It specifies the height of triangle.
  • borderColor: This parameter defines the border color of the triangle.

Example: This example uses FabricJS to enable the borderColor of the canvas-like triangle as given below. Try borderColor the object after enabling borderColor property, it will color the triangle border by defined color.
