你可以直接使用win32 API.
1)首先将焦点放在您要截图的应用程序上.

2)Win32 API可以帮助屏幕截图：
- import win32gui
- import win32ui
- hwnd = win32gui.FindWindow(None,windowname)
- wDC = win32gui.GetWindowDC(hwnd)
- dcObj=win32ui.CreateDCFromHandle(wDC)
- cDC=dcObj.CreateCompatibleDC()
- dataBitMap = win32ui.CreateBitmap()
- dataBitMap.CreateCompatibleBitmap(dcObj,w,h)
- cDC.SelectObject(dataBitMap)
- cDC.BitBlt((0,0),(w,h),dcObj,(0,win32con.SRCCOPY)
- dataBitMap.SaveBitmapFile(cDC,bmpfilenamename)
- # Free Resources
- dcObj.DeleteDC()
- cDC.DeleteDC()
- win32gui.ReleaseDC(hwnd,wDC)
- win32gui.DeleteObject(dataBitMap.GetHandle())
