The opencv Mat object (java)
I'am new to opencv I want to understand the opencv Mat class
For the get method
I try the first one int get(int row, int col, byte[] data) with this example
Mat mat = Mat.eye( 3, 3, CvType.CV_8UC1 );
System.out.println(mat.dump());
byte[] data = new byte[mat.cols() * mat.rows() * (int)mat.elemSize()];
System.out.println(data.length);-->9
System.out.println( mat.get(0, 0, data)); -->9
but I can't understand
1) the role of the third argument byte[] data
2) and the result
