How do i Resize image inside picturebox in vb.net?

Question

I want to resize the images inside the picturebox.

I'd made this already

Private img As Bitmap
rec = New Rectangle(0, 0, 520, 470)


Private Sub PicFace_Paint(ByVal sender As Object, ByVal e As PaintEventArgs) Handles PicFace.Paint
    PicFace.SizeMode = PictureBoxSizeMode.Zoom
    Draw(e.Graphics, rec.Width, rec.Height)
    'Draw(e.Graphics, PicFace.Width, PicFace.Height)

End Sub

resize the picturebox...
img = PicFace.Image
    rec.Width = rec.Width + 10
    rec.Height = rec.Height + 10
    PicFace.Refresh()

How do i do it?
