I have the file saved as bmp format in c #. A strange problem arose in the process of converting files from a c ++ opencv.

Save the file format is bmp -> jp2

The following code is the source code that I work.

//////////////////////////////////////////////////////////

extern "C" __declspec(dllexport) void ConvertJp2to16bitGrayScaleJp2(char* InputFileName,char* OutputFileName)
{
// TODO: 응용 프로그램의 동작은 여기에서 코딩합니다.

//          Mat image,fin_img;
//          image = imread("제목 없음-6.png", CV_LOAD_IMAGE_COLOR);   // Read the file

cv::Mat image(128,128,CV_16UC1);
image = cv::imread(InputFileName, CV_LOAD_IMAGE_ANYDEPTH  | CV_LOAD_IMAGE_ANYCOLOR);

if (!image.data) {
    std::cout << "Image file not found\n";
    return ;
}
    cv::Mat pic16bit(128,128,CV_16UC1);
    std::cout << image.depth() << std::endl;

// 
//cv::cvtColor(image, image, CV_RGB2GRAY);

image.convertTo(pic16bit,CV_16UC1);
//cvConvertScale(&image,&pic16bit,2.0,0);
//pic16bit=image;

//pic16bit.convertTo(pic16bit, CV_16U, );
//          image.convertTo(pic16bit, CV_16U, 255); //convert to 16-bit by multiplying all values by 255
// 
//          params.append(cv.CV_IMWRITE_PNG_COMPRESSION);
//          params.append(8);

//  namedWindow( "Result window", CV_WINDOW_AUTOSIZE );   
//  imshow( "Result window", image );
// 
//  namedWindow( "Result window", CV_WINDOW_AUTOSIZE );   
//  imshow( "Result window", pic16bit );
// create image window named "asdfasdf"
//cv::namedWindow("asdfasdf");
//divide( image, pic16bit, image, image.depth() == 16 ? UCHAR_MAX : USHRT_MAX );
// show the image on window
//imshow("asdfasdf", pic16bit);

vector<int> compression_params;
compression_params.push_back(CV_16U);


imwrite(OutputFileName,pic16bit,compression_params);



//          // wait for key
cv::waitKey(0);
// 
//          
//          Mat imageNew8, newImage16;
//          newImage16 = imread("dest.jp2", CV_LOAD_IMAGE_ANYDEPTH|CV_LOAD_IMAGE_ANYCOLOR);
//          newImage16.convertTo(imageNew8, CV_8UC1, 1.0/255);




return;
}

If you check the work product to the code is 16bit unsigend gray scale images created through

Format image of a strange mix of stripes and the width is cut in half.

What is one to do wrong and right way to get the results?
