如何在 Python 中检测屏幕像素的颜色

Question

我想知道我们如何使用 pyautogui 检测像素的颜色不起作用，因为它给出了错误OSError: windll.user32.ReleaseDC failed: return 0是否有其他方法可以检测像素的颜色

我的代码是：

import pyautogui
from time import sleep as wait
import keyboard

while keyboard.is_pressed('q') == False:
    if pyautogui.pixel(565, 171)[0] == 0:
        pyautogui.click(565, 171)
        wait(0.01)
    if pyautogui.pixel(670, 171)[0] == 0:
        pyautogui.click(670, 171)
        wait(0.01)
    if pyautogui.pixel(769, 171)[0] == 0:
        pyautogui.click(769, 171)
        wait(0.01)
    if pyautogui.pixel(873, 171)[0] == 0:
        pyautogui.click(873, 171)
        wait(0.01)

我通过处理错误来修复它

import pyautogui
from time import sleep as wait
import keyboard

while keyboard.is_pressed('q') == False:
    try:
        if pyautogui.pixel(565, 171)[0] == 0:
            pyautogui.click(565, 171)
            wait(0.01)
        if pyautogui.pixel(670, 171)[0] == 0:
            pyautogui.click(670, 171)
            wait(0.01)
        if pyautogui.pixel(769, 171)[0] == 0:
            pyautogui.click(769, 171)
            wait(0.01)
        if pyautogui.pixel(873, 171)[0] == 0:
            pyautogui.click(873, 171)
            wait(0.01)
    except Exception as e:
        print(e)
