Examples

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;
void InitializeBitmap()
{
   try
   {
      bitmap1 = dynamic_cast<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." );
   }

}

void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   if ( bitmap1 != nullptr )
   {
      bitmap1->RotateFlip( RotateFlipType::Rotate180FlipY );
      PictureBox1->Image = bitmap1;
   }
}

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;
    }
}

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

Remarks

The image is rotated in a clockwise direction.
