Capturar contenido en un Picturebox

[Brian1511]

Bueno como dice el titulo solo quiero saber si es posible capturar lo que este dentro de un picturebox, al decir capturar es tirar un screenshot dentro de los objetos que esten en el picturebox es decir un ejemplo mas grafico:




Quisiera hacer una captura a todo lo que este en su interior, pero en forma de imagen

Gracias de antemano!
Un saludo!

y en el formulario lo llamas asi con un zoom de 150 (si lo queres tal cual le pones 100)

Private Sub Command1_Click()
    Me.Picture = GetPictureControl(Picture1, 150)
End Sub
