Copy an cv::Mat inside a ROI of another one

Question

I need to copy a `cv::Mat` image (source) to an ROI of another (Destination) `cv::Mat` image. 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?

Accepted Answer

OpenCV 2.4:

```
src.copyTo(dst(Rect(left, top, src.cols, src.rows)));
```

OpenCV 2.x:

```
Mat dst_roi = dst(Rect(left, top, src.cols, src.rows));
src.copyTo(dst_roi);
```
