在VB中將位圖轉換爲RGB

Question

請參閱下面的代碼。我設法使用VB截取了我的計算，並將其存儲爲位圖。我想將這個位圖（很快！）轉換爲一個rgb值的數組。

任何簡單的代碼，可以做到這一點？

' Capture screen code 
Dim bounds As Rectangle 
Dim screenshot As System.Drawing.Bitmap 
Dim graph As Graphics 
bounds = Screen.PrimaryScreen.Bounds 
screenshot = New System.Drawing.Bitmap(bounds.Width, bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppRgb) 
graph = Graphics.FromImage(screenshot) 
graph.CopyFromScreen(bounds.X, bounds.Y, 0, 0, bounds.Size, CopyPixelOperation.SourceCopy) 

' Display the captured image 
Display.Image = screenshot
