Mat mRgb = Imgcodecs.imread("test.jpg");
MatOfInt iRgb = new MatOfInt(CvType.CV_32S);// middle type
mRgb.convertTo(iRgb, CvType.CV_32S);// 复制mRgb的数据到 iRgb
int[] dataArray = new int[(int)(iRgb.total()*iRgb.channels())];
iRgb.get(0,0, dataArray);// iRgb数据 int[]

After allocating the array,

byte imageInByte[] = new byte[originalImage.total() * originalImage.channels()];

You can copy the array from C++/JNI,

originalImage.get(0, 0, imageInByte);

To update the array in C++/JNI

originalImage.put(0, 0, imageInByte);
