如何在 Python 中檢測屏幕像素的顏色

Question

我想知道我們如何使用 pyautogui 檢測像素的顏色不起作用，因為它給出了錯誤OSError: windll.user32.ReleaseDC failed: return 0是否有其他方法可以檢測像素的顏色

我的代碼是：

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)

Answer 1

我通過處理錯誤來修復它

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)
