如何将当前屏幕捕获为图像？

pip install pyautogui

import pyautogui
import cv2

# 捕获屏幕
screenshot = pyautogui.screenshot()

# 将截图保存为图像文件
screenshot.save('screenshot.png')

# 使用OpenCV显示截图
img = cv2.imread('screenshot.png')
cv2.imshow('Screenshot', img)
cv2.waitKey(0)
cv2.destroyAllWindows()

html2canvas(document.body).then(function(canvas) {
  // 将截图保存为图像文件
  var img = canvas.toDataURL("image/png");
  var link = document.createElement("a");
  link.download = "screenshot.png";
  link.href = img;
  link.click();
});
