the C-api you're trying to use was deprecated 10 years ago, and now it's entirely gone.

rewrite your program, and use the c++ api (cv::Mat)

I try this but they tell me that use of uneclared identifier 'cvSet2D' and I try with cv:Set but the dont have any funcion similar.

Mat azul, image;


for(int i=0;i<azulrow;i++){
        for(int j=0;j<azulweigth;j++) {



If you can guide me i woud be very grateul

you won't be able to compile this using opencv 4.

you could checkout the 3.4 branch instead and rebuild, maybe it will compile.
