如何使用pyautogui指定多個區域？

我的螢屏someButton.png上可能會出現四個區域。我想指定這四個區域而不是整個螢屏。

我知道我們可以像下面的例子一樣指定單個區域，但檔案沒有說明多個區域。

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

我試過添加多個關鍵字：

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

但我得到了錯誤 SyntaxError: keyword argument repeated: region

如何在pyautogui中指定要搜索的多個區域？

我現在正在使用的代碼：

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)

和錯誤資訊：

l 正在函式上方加載 l = r"C:\Users\x\OneDrive\froggy-pirate-master\avoidShips\eventfarm\l.jpg"

該檔案仍然存在，在回圈中傳遞區域元組是否會更改某些內容的格式？

uj5u.com熱心網友回復：

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}")

我查看了源代碼，由于在一個區域中查找影像的部分可能非常慢，與可能的影像位置呈線性關系，因此最好locateOnScreen為每個區域單獨呼叫（而不是在一個區域上呼叫一次）包含您的四個區域）。

閱讀源代碼似乎也為了速度，您應該同時安裝cv2（OpenCV）和numpy安裝。如果您只有其中之一，或者沒有，它將回退到使用pillow.
