试试高版本的openCV吧,Mat比IplImage好用多了。帮你写了下
#include <opencv2\opencv.hpp>
#include<iostream>
using namespace cv;
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
Mat img;
img = imread("D:\\download\\logo.png");
imshow("show", img);
for (int i = 0; i < img.rows; i++)
for (int j = 0; j < (img.cols/2); j++)
{
int tmpB = img.at<Vec3b>(i, j)[0];
int tmpG = img.at<Vec3b>(i, j)[1];
int tmpR = img.at<Vec3b>(i, j)[2];
img.at<Vec3b>(i, j)[0] = img.at<Vec3b>(i, img.cols - j - 1)[0];
img.at<Vec3b>(i, j)[1] = img.at<Vec3b>(i, img.cols - j - 1)[1];
img.at<Vec3b>(i, j)[2] = img.at<Vec3b>(i, img.cols - j - 1)[2];
img.at<Vec3b>(i, img.cols - j - 1)[0] = tmpB;
img.at<Vec3b>(i, img.cols - j - 1)[1] = tmpG;
img.at<Vec3b>(i, img.cols - j - 1)[2] = tmpR;
}
imshow("spieglt", img);
waitKey();
return 0;
}

if(argc<2),你这样写是需要从控制台命令窗口调用程序并传入参数的
