Draw Rectangle Using Web Application In TypeScript

In this article I explain how to draw a rectangle in a web application using TypeScript.

In this article, we draw a rectangle 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#.

Provide the name of your application as "Draw_Rectangle" 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.

Coding

Rectangle.ts

/// <reference path="Kinect.d.ts" />

class Draw_Rectangle {

    Rectangle() {

        var stage = new Kinetic.Stage({ container: 'content'});

        var layer = new Kinetic.Layer();

        var rectangle = new Kinetic.Rect({width:200,height:200,cornerRadius:5,

        fill:'Blue',strokeWidth:10,stroke:'Black'});

        layer.add(rectangle);

        stage.add(layer);

    }

}

window.onload = () =>

{

    var obj = new Draw_Rectangle();

    obj.Rectangle();

};

            stroke: 'Black'

        });

        layer.add(rectangle);

        stage.add(layer);

    };

    return Draw_Rectangle;

})();

window.onload = function () {

    var obj = new Draw_Rectangle();

    obj.Rectangle();

};

//@ sourceMappingURL=Rectangle.js.map
