Fabric.js | Triangle cornerDashArray Property

In this article, we are going to see how to set the dash pattern of controlling corners of the 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 color, 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 set a dash pattern of controlling corners of the canvas triangle using cornerDashArray property and render the triangle on the Canvas as given in the below example.

Syntax:

fabric.Triangle({
    width: number,
    height: number,
    cornerDashArray: array
});

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.
  • cornerDashArray: This parameter defines the dash pattern of the controlling corners.

Example: This example uses FabricJS to set a dashed pattern of controlling corners of the canvas-like triangle as given below. You have to click on the object to see the dash pattern of controlling corners.
