Question

蟒蛇新手（过去几个月内），我很享受。它易于理解和使用。除了这种情况！

我写了一个脚本，用于登录使用selenium的网站，导航到特定页面，输入日期值并显示我需要的结果。它滚动到位，然后我需要截取该页面的一部分。起初我只是将它保存在整个屏幕上，我稍后会裁剪它，但我相信只有截取我需要的区域才有可能（而且效率更高）。

我已经尝试了多种方法来定位角落开始的位置并选择区域，最终决定使用locateCenterOnScreen与我想要的点的示例屏幕截图一起使用pyautogui，其中心标记左上角我要保存的整个部分。这确保了如果窗口每次都不在同一个地方，它将准确地保存正确的区域，无论它在哪里。

因此，使用

location = pyautogui.locateCenterOnScreen('ctr_cornerScreenshot.PNG')

返回正确的（X，Y）值以正确定位屏幕截图的坐标。然后，我正在使用

screengrabPic = pyautogui.screenshot(region=(location, 720, 340)) screengrabPic.save("transactions.png")

错误结果为

AssertionError: region argument must be a tuple of four ints

我确定因为location传入的区域参数，我已尝试(int(location)或'locationX, locationY,

我想我会伸手去寻求帮助，而不是更多地转动我的车轮。谢谢！

好的，所以我做了更多的试验和错误，然后找到了最终的解决方案。

在pyautogui.readthedocs上，它解释了这种语法，但并不是具体要求首先运行定位中心，然后再运行locationX和locationY。

可以将locateOnScreen坐标传递给X Y参数以使用Python屏蔽某个区域吗？
