如何使用 pyautogui 指定多个区域？

Question

我的屏幕上有四个区域 someButton.png 可能会出现。我想指定这 4 个区域而不是整个屏幕。

我知道我们可以像下面的例子一样指定单个区域，但是 documentation 没有说明多个区域。

    import pyautogui
    pyautogui.locateOnScreen('someButton.png', region=(0,0, 300, 400))

我试过添加多个关键字：

pyautogui.locateOnScreen('someButton.png', region=(0,0, 300, 400), region=(0,0, 400, 500))

但我收到错误 SyntaxError: keyword argument repeated: region

如何在pyautogui中指定多个区域进行搜索？

我现在使用的代码：

def l():
    l = py.locateOnScreen(levelupimage, confidence=0.90)

    regions = {
        "region 1": (476, 268, 736, 320),
        "region 2": (1328, 268, 1591, 320),
        "region 3": (276, 745, 564, 806),
        "region 4": (1130, 745, 1422, 803)
    }

    for region in regions:
        l = py.locateOnScreen('levelup.jpg', region=region)
        if l != None:
            py.click(l)

错误信息：

文件还在，在循环中传递区域元组会改变某些东西的格式吗？

Answer 1

regions = {
    "region 1": (0, 0, 300, 400),
    "region 2": (300, 0, 300, 400),
    "region 3": (0, 400, 300, 400),
    "region 4": (300, 400, 300, 400)
}
for region_name, region in regions.items():
    rect = pyautogui.locateOnScreen('someButton.png', region=region)
    if rect:
        print(f"found in {region_name} at this (x,y,w,h): {rect}")

我查看了源代码，由于在区域中查找图像的部分可能非常慢，与可能的图像位置呈线性关系，因此最好为每个区域分别调用 locateOnScreen （而不是在包含您的四个区域的区域上调用一次）。

阅读源代码看来，为了提高速度，您应该同时安装 cv2 (OpenCV) 和 numpy。如果您只有其中之一，或 none，它将退回到使用 pillow。
