Vb.net 保存picturebox的图像

所以我有这个代码：

Private Sub button28_Click(sender As Object, e As EventArgs) Handles button28.Click
    Dim bounds As Rectangle
    Dim screenshot As System.Drawing.Bitmap
    Dim graph As Graphics
    bounds = PicOuterBorder.Bounds
    screenshot = New System.Drawing.Bitmap(bounds.Width, bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)
    graph = Graphics.FromImage(screenshot)
    graph.CopyFromScreen(bounds.X, bounds.Y, 0, 0, bounds.Size, CopyPixelOperation.SourceCopy)
    picFinal.Image = screenshot
    'this takes a screenshot
End Sub

PicouterOrder

是我表单上的一个图片盒

PicFinal

是另一个显示图片框。但这段代码让我明白了这一点：它基本上是一个屏幕截图，从屏幕的原点开始，大小为PicouterOrder。但是，

Me.Bounds

而不是

PicOuterBorder.Bounds

可以正常工作并获得一个完整的屏幕截图。我想让picFinal有一个PicOuterOrder的屏幕截图

使您的代码适应如下内容：

Public Sub SaveImage(filename As String, image As Image, Encoder As ImageCodecInfo, EncParam As EncoderParameter)

Dim path As String = System.IO.Path.Combine(My.Application.Info.DirectoryPath, filename & ".jpg")
Dim mySource As New Bitmap(image.Width, image.Height)
Dim grfx As Graphics = Graphics.FromImage(mySource)
grfx.DrawImageUnscaled(image, Point.Empty)
grfx.Dispose()
mySource.Save(filename, System.Drawing.Imaging.ImageFormat.Jpeg)
mySource.Dispose()

End Sub

试试下面的代码。您必须使用

指向屏幕

将控制坐标映射到屏幕坐标。我已将

PicOuterBorder

放置在面板

PanelPicture

内

PanelPicture

没有任何边框，而

PicOuterOrder

可以有任何类型的边框样式。下面的代码拍摄了面板的快照

Private Sub button28_Click(sender As Object, e As EventArgs) Handles button28.Click
    Dim graph As Graphics = Nothing
    Dim bounds As Rectangle = Nothing
    Dim screenshot As System.Drawing.Bitmap

    Dim location As Drawing.Point = PanelPicture.PointToScreen(Drawing.Point.Empty)
    screenshot = New System.Drawing.Bitmap(PanelPicture.Width, PanelPicture.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)
    graph = Graphics.FromImage(screenshot)
    graph.CopyFromScreen(location.X, location.Y, 0, 0, PanelPicture.Size, CopyPixelOperation.SourceCopy)
    picFinal.Image = screenshot

    graph.Dispose()
End Sub

但首先，我需要调整自己来理解你说的话。请澄清一下。
