Méthode Description

DestroyPreviewWindow ( ) : void

Destroys the preview window.
FrameCallbackProc ( IntPtr hWnd, System.Win32 &VideoHeader ) : int

Called on each frame update.

In order to draw on the resulting image, it must first be copied. This is because setting the bitmap data pointer directly and rotating the image can lead to random exceptions. This is expensive though. So by design, this doesn't happen automatically. See the following sites for details about this: http://msdn.microsoft.com/en-us/library/system.drawing.image.rotateflip.aspx http://social.msdn.microsoft.com/Forums/en-IE/csharplanguage/thread/affa1855-e1ec-476d-bfb1-d0985971f394
