In this simple article you will learn that how to make reflection of an image in vb and C #.net.

 Graphics:

While playing with the graphics you must keep the following point in your mind:

You can’t draw graphics on simple load event of the form. To create graphics on the form, you must override the onpaint() function of the form.

The syntax of the onpaint() function is:

C#:

protected override void OnPaint (PaintEventArgs e)

{

}

VB:

Dim e As PaintEventArgs

 

Me.OnPaint(e)

In this article I will tell you that how we can make reflection of an image.

Create a graphics object. The next function is the drawImage(). This function has 29 overloaded methods,depending on your requirements you can use any of them. The return type of this function is void.

The syntax of the DrawImage() function is:

C#:

g.DrawImage(image, cx / 2, cy / 2, cxImage, cyImage);

VB:

g.DrawImage(image, cx / 2, cy / 2, cxImage, cyImage)

ClientSize.Width and  ClientSize.height, these two properties gives you the width and height of the client area respectively. The return type of these properties  is an integer and to set them an integer is required.

 

To demonstrate make a new window application and write the following code on form’s onpaint event:

C#:

protected override void OnPaint(PaintEventArgs e)

        {

            Graphics g = e.Graphics;

            int cxImage = image.Width;

            int cyImage = image.Height;

            int cx=ClientSize.Width;

            int cy = ClientSize.Height;

            g.DrawImage(image, cx / 2, cy / 2, cxImage, cyImage);

            g.DrawImage(image, cx / 2, cy / 2, -cxImage, cyImage);

            g.DrawImage(image, cx / 2, cy / 2, cxImage, -cyImage);

            g.DrawImage(image, cx / 2, cy / 2, -cxImage, -cyImage);

        }

VB:

Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)

    Dim g As Graphics = e.Graphics

    Dim cxImage As Integer = image.Width

    Dim cyImage As Integer = image.Height

    Dim cx As Integer = ClientSize.Width

    Dim cy As Integer = ClientSize.Height

    g.DrawImage(image, cx / 2, cy / 2, cxImage, cyImage)

    g.DrawImage(image, cx / 2, cy / 2, -cxImage, cyImage)

    g.DrawImage(image, cx / 2, cy / 2, cxImage, -cyImage)

    g.DrawImage(image, cx / 2, cy / 2, -cxImage, -cyImage)

End Sub

Now write the following code on FORM LOAD event:

C#:

private void Form1_Load(object sender, EventArgs e)

        {

            this.Text = "DEVASP APPLICATION";

       }

Vb:

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)

    Me.Text = "DEVASP APPLICATION"

    End Sub
