The following code example demonstrates how to set the RotateFlip property of an Image and the RotateFlipType enumeration.

This example is designed to be used with a Windows Form that contains a PictureBox named PictureBox1 and a button named Button1. Paste the code into a form, call InitializeBitmap from the form's constructor or Load event-handling method and associate Button1_Click with the button's Click event. Ensure the file path to the bitmap is valid on your system.

Dim bitmap1 As Bitmap

Private Sub InitializeBitmap()
    Try
        bitmap1 = CType(Bitmap.FromFile("C:\Documents and Settings\All Users\" _
            & "Documents\My Music\music.bmp"), Bitmap)
        PictureBox1.SizeMode = PictureBoxSizeMode.AutoSize
        PictureBox1.Image = bitmap1
    Catch ex As System.IO.FileNotFoundException
        MessageBox.Show("There was an error. Check the path to the bitmap.")
    End Try 


End Sub 

Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    If bitmap1 IsNot Nothing Then
        bitmap1.RotateFlip(RotateFlipType.Rotate180FlipY)
        PictureBox1.Image = bitmap1
    End If 

End Sub
