java - Display image in mat with jframe (OpenCV 3.00) -


how display mat image in jframe. seticon() not accept mat parameter. image should used in opencv 3.00 before displaying. opencv can open mat images. there way convert image? 

public void displayimage() {                 mat image = imgcodecs.imread(getclass().getresource("lena.png").getpath());      jframe frame=new jframe();     frame.setlayout(new flowlayout());                jlabel lbl=new jlabel();     lbl.seticon(image);     frame.add(lbl);            frame.setvisible(true);     frame.setdefaultcloseoperation(jframe.exit_on_close);  }

i did find code convert has highgui no longer in opencv 3.00.

matofbyte bytemat = new matofbyte(); highgui.imencode(".bmp", mat, bytemat); return new image(new bytearrayinputstream(bytemat.toarray()));

convert mat bufferedimage, draw on panel, canvas or similar:

public static bufferedimage bufferedimage(mat m) {     int type = bufferedimage.type_byte_gray;     if ( m.channels() > 1 ) {         type = bufferedimage.type_3byte_bgr;     }     bufferedimage image = new bufferedimage(m.cols(),m.rows(), type);     m.get(0,0,((databufferbyte)image.getraster().getdatabuffer()).getdata()); // pixels     return image; }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
