需将<代码>cv:Mat 图像(资料来源)复制到另一个仪器(印章)<代码>cv:
I found this reference, but it seems that it does not work for my case. Do you have any pointers how could I do this using the OpenCV C++ interface?

开放CV 2.4:
src.copyTo(dst(Rect(left, top, src.cols, src.rows)));
开放CV 2.x:
Mat dst_roi = dst(Rect(left, top, src.cols, src.rows));
src.copyTo(dst_roi);
除上述答复外,如果你希望复制一个较小的开放区域<代码>Mat至另一个<代码>
src(Rect(left,top,width, height)).copyTo(dst);
我的工作方式如下:
Mat imgPanel(100, 250, CV_8UC1, Scalar(0));
Mat imgPanelRoi(imgPanel, Rect(0, 0, imgSrc.cols, imgSrc.rows));
imgSrc.copyTo(imgPanelRoi);
imshow("imgPanel", imgPanel);
waitKey();
