我这样做是为了获取Image的每个像素值并在Console上打印它

include "stdafx.h"
include "opencv2/imgproc/imgproc.hpp"
include "opencv2/highgui/highgui.hpp"
include <stdlib.h>
include <stdio.h>

using namespace cv;

int main( int argc, char** argv )
{
    IplImage *img = cvLoadImage("lena.jpg");
    CvMat *mat = cvCreateMat(img->height,img->width,CV_32FC3 );
    cvConvert( img, mat );
    for(int i=0;i<10;i++)
       {
         for(int j=0;j<10;j++)
           {
              CvScalar scal = cvGet2D( mat,j,i);
              printf( "(%.f,%.f,%.f)  ",scal.val[0], scal.val[1], scal.val[2] );
           }
         printf("\n");
       }
    waitKey(1);
    return 0;
 }

是否有更好的方法来获取每个像素值以及txt.files中的头和通道值
