pyautogui.locateOnScreen 无法定位图像

Question

我尝试在屏幕上找到图像。

我尝试重新安装 pyautogui 和 Pillow 但它总是显示这个：

Traceback (most recent call last):
  File "c:\Users\win0908\Desktop\PY\stickman.py", line 9, in <module>
    if pyautogui.locateOnScreen('stickman.png', region=(150,175,350,600), grayscale=True, confidence=0.8) != None:
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise ValueError('needle dimension(s) exceed the haystack image or region dimensions')
ValueError: needle dimension(s) exceed the haystack image or region dimensions

这是我的代码：

import pyautogui

if pyautogui.locateOnScreen('stickman.png', confidence=0.8) != None:
    print("I can see it")

请帮忙！

Answer 1

该错误试图告诉您

stickman.png

图像大于它正在搜索的区域。请参阅错误的以下部分：

 File "c:\Users\win0908\Desktop\PY\stickman.py", line 9, in <module>
    if pyautogui.locateOnScreen('stickman.png', region=(150,175,350,600), grayscale=True, confidence=0.8) != None:

它正在区域

(150,175,350,600)

（这些是代表区域的x、y、宽度、高度值）中搜索，该区域的尺寸比

stickman.png

图像更小
