else:
return True
grab_tuple = (start_x, start_y, end_x, end_y)
print grab_tuple
im = ImageGrab.grab(grab_tuple)
im.save("test.jpg", 'jpeg')
return True

hm = pyHook.HookManager()
hm.MouseLeftDown = on_mouse_left_down
hm.MouseLeftUp = on_mouse_left_up
hm.HookMouse()
pythoncom.PumpMessages()

再做个屏幕遮罩就完美啦
