Draw Regular Polygon In TypeScript

In this article, we draw a polygon in a web application using TypeScript.

First we download some files in the following attachment:

  1. Kinect.d.ts

  2. Kinectic.min.js

These files are added to the project, then use the following procedure.

Step 1

Open Visual Studio 2012 and click "File" -> "New" -> "Project...". A window is opened. In this window, click "HTML Application for TypeScript" under Visual C#.

Give the name of your application as "Draw_Regular_Polygon" and then click Ok.

Step 2

After this session the project has been created; a new window is opened on the right side. This window is called the Solution Explorer. The Solution Explorer contains the ts file, js file and css file and aspx page.

        var r_polygon = new Kinetic.RegularPolygon({

            x: stage.getWidth() / 2,

            y: stage.getHeight() / 2,

            sides: 6,

            radius: 90,

            fill: 'green',

            stroke: 'black',

            strokeWidth: 4

        });

        layer.add(r_polygon);

        stage.add(layer);

    }

}

window.onload = () =>

{

    var obj = new Regular_Ploygon();

    obj.R_Polygon();

}
