做自动化过程中时长会遇到一些截图操作，那么在做客户端的时候，应该怎么进行截图呢？
在pywinauto中存在自带的截图函数 capture_as_image()
源码：
def capture_as_image(self, rect=None): """ Return a PIL image of the control. See PIL documentation to know what you can do with the resulting image. """ control_rectangle = self.rectangle() if not (control_rectangle.width() and control_rectangle.height()): return None # PIL is optional so check first if not ImageGrab: print("PIL does not seem to be installed. " "PIL is required for capture_as_image") self.actions.log("PIL does not seem to be installed. " "PIL is required for capture_as_image") return None if rect: control_rectangle = rect # get the control rectangle in a way that PIL likes it width = control_rectangle.width() height = control_rectangle.height() left = control_rectangle.left right = control_rectangle.right top = control_rectangle.top bottom = control_rectangle.bottom box = (left, top, right, bottom) # check the number of monitors connected if (sys.platform == ‘win32‘) and (len(win32api.EnumDisplayMonitors()) > 1): hwin = win32gui.GetDesktopWindow() hwindc = win32gui.GetWindowDC(hwin) srcdc = win32ui.CreateDCFromHandle(hwindc) memdc = srcdc.CreateCompatibleDC() bmp = win32ui.CreateBitmap() bmp.CreateCompatibleBitmap(srcdc, width, height) memdc.SelectObject(bmp) memdc.BitBlt((0, 0), (width, height), srcdc, (left, top), win32con.SRCCOPY) bmpinfo = bmp.GetInfo() bmpstr = bmp.GetBitmapBits(True) pil_img_obj = Image.frombuffer(‘RGB‘, (bmpinfo[‘bmWidth‘], bmpinfo[‘bmHeight‘]), bmpstr, ‘raw‘, ‘BGRX‘, 0, 1) else: # grab the image and get raw data as a string pil_img_obj = ImageGrab.grab(box) return pil_img_obj
上面的操作方法已经了解了，我们实战进行操作，看看进行如何截图，这里我们截图后，要进行保存，可以根据路径保存或者直接保存在当前目录
# coding:utf-8 from pywinauto import Application # 打开记事本 app = Application().start(r‘C:\Windows\System32\notepad.exe‘) win = app[‘无标题 - 记事本‘] # 截图进行保存 a = win.capture_as_image().save(‘123.png‘)
