I asked that before and I have been told to use cvCopy and

Unfortunately the "Paul Lammertsma" code has mixed up indexes here you have fixed code:

void drawImage(IplImage* target, IplImage* source, int x, int y) {

    for (int ix=0; ixwidth; ix++) {
        for (int iy=0; iyheight; iy++) {
            int r = cvGet2D(source, iy, ix).val[2];
            int g = cvGet2D(source, iy, ix).val[1];
            int b = cvGet2D(source, iy, ix).val[0];
            CvScalar bgr = cvScalar(b, g, r);
            cvSet2D(target, iy+y, ix+x, bgr);
        }
    }
}
