在opencv4nodejs中使用同时变量时发生翻转图像错误

npm update opencv4nodejs

const cv = require('opencv4nodejs');

// 读取图像
let img = cv.imread('path_to_your_image.jpg');

// 水平翻转
let flippedHorizontal = img.flip(1);

// 垂直翻转
let flippedVertical = img.flip(0);

// 显示结果
cv.imshow('Flipped Horizontal', flippedHorizontal);
cv.imshow('Flipped Vertical', flippedVertical);
cv.waitKey();

const cv = require('opencv4nodejs');

try {
  // 读取图像
  let img = cv.imread('path_to_your_image.jpg');
  if (img.empty) {
    throw new Error('Image not found or unable to read');
  }

  // 水平翻转
  let flippedHorizontal = img.flip(1);
  if (flippedHorizontal.empty) {
    throw new Error('Failed to flip image horizontally');
  }

  // 垂直翻转
  let flippedVertical = img.flip(0);
  if (flippedVertical.empty) {
    throw new Error('Failed to flip image vertically');
  }

  // 显示结果
  cv.imshow('Flipped Horizontal', flippedHorizontal);
  cv.imshow('Flipped Vertical', flippedVertical);
  cv.waitKey();
} catch (error) {
  console.error('Error:', error.message);
}
