怎样反转Image里的图片？

Private Sub Form_Load()
Picture1.Visible = False
Picture1.AutoRedraw = True
Image1.Picture = LoadPicture("C:\WINDOWS\Web\exclam.gif")
End Sub

Private Sub Command1_Click()
Picture1.PaintPicture Image1.Picture, 0, 0, Image1.Width, Image1.Height, 0, Image1.Height, Image1.Width, -Image1.Height
Image1.Picture = Picture1.Image
Picture1.Cls
End Sub

是旋转还是翻转？
