用位图对象的Clone 方法就可以获取图片某个区域成一个新的位图对象，下面例子：
Private Sub Form1_Click(sender As Object, e As EventArgs) Handles Me.Click
Dim img As New Bitmap("d:\015.jpg")
Dim rc As Rectangle = New Rectangle(500, 500, 600, 600) '起点和长宽
Dim newImg As Bitmap = img.Clone(rc, Imaging.PixelFormat.Format32bppArgb)
Me.CreateGraphics.DrawImage(newImg, 0, 0)
End Sub
Private Sub Form1_Click(sender As Object, e As EventArgs) Handles Me.Click
Dim img As New Bitmap("d:\015.jpg")
Dim rc As Rectangle = New Rectangle(500, 500, 600, 600) '起点和长宽
Dim newImg As Bitmap = img.Clone(rc, Imaging.PixelFormat.Format32bppArgb)
Me.CreateGraphics.DrawImage(newImg, 0, 0)
End Sub
