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.

Bitmap bitmap1;

private void InitializeBitmap()
{
    try
    {
        bitmap1 = (Bitmap)Bitmap.FromFile(@"C:\Documents and Settings\" + 
            @"All Users\Documents\My Music\music.bmp");
        PictureBox1.SizeMode = PictureBoxSizeMode.AutoSize;
        PictureBox1.Image = bitmap1;
    }
    catch(System.IO.FileNotFoundException)
    {
        MessageBox.Show("There was an error." + 
            "Check the path to the bitmap.");
    }


}

private void Button1_Click(System.Object sender, System.EventArgs e)
{

    if (bitmap1 != null)
    {
        bitmap1.RotateFlip(RotateFlipType.Rotate180FlipY);
        PictureBox1.Image = bitmap1;
    }

}
