矩阵的边界填充类型

Mat C =(Mat_<uchar>(3,3)<<1,2,3,4,5,6,7,8,9);
    uchar *data = NULL;
    for (int row = 0; row < C.rows; row++)
    {
        data = (uchar *)C.ptr<uchar>(row);
        cout << "[";
        for (int col = 0; col < C.cols; col++)
        {
            cout << (int)data[col] << " ";
        }
        cout << "]"  << endl;
    }
    Mat D;
    copyMakeBorder(C, D, 2, 2, 2, 2, BORDER_REPLICATE);
