raise ImageNotFoundException # Raise PyAutoGUI’s ImageNotFoundException. pyautogui.ImageNotFoundException

0.9.54版本的pyautogui查找一张不存在的图片时,会出现一个异常

File "C:\Users\rkey\AppData\Local\Programs\Python\Python38\lib\site-packages\pyautogui\__init__.py", line 174, in wrapper
    raise ImageNotFoundException  # Raise PyAutoGUI's ImageNotFoundException.
pyautogui.ImageNotFoundException

导致无法判断结果是None.

比如这样会出问题:

img_path= r".\\image_for_identify\\free_finished.jpg"
while location is None and time.time() - start_time < timeout:
    location = pyautogui.locateOnScreen(imageFile,grayscale=True, confidence=0.8)
    if location is None:
        time.sleep(0.1)

于是我异常捕获了一下,发现提示"该异常未找到 "

我反复在想这个异常,突然发现这个pyautogui.ImageNotFoundException说不定就是一个处理异常的包呢,

再来一下异常处理,专门处理这个异常,发现能找到这个异常了

导入一下试试

from pyautogui import ImageNotFoundException
try:
    location = pyautogui.locateOnScreen(图片路径, grayscale=True, confidence=0.8)
if location is None:
    # 如果location是None，则抛出ImageNotFoundException
    raise ImageNotFoundException('无法在屏幕上找到指定的图像。')
else:
    # 如果找到了图像，执行一些操作
    print(f"找到了图像，位置是：{location}")
except ImageNotFoundException as e:
    # 捕获ImageNotFoundException异常
    print(e)

ok,这个异常能捕获了
