The at operator is very simple to use and requires one parameter … While you can probably achieve what you want with std::shift_right, the appropriate algorithm to do what you've described is std::rotate, which you can use without c++20 as well: std::rotate (seq.begin (), seq.end () - 1, seq.end ()); Here's a demo. The reason the shift_right version doesn't work is that you have an iterator to the last element.

Let the pixels by which the image needs to shifted be tx and ty. Then you can define a translation matrix : (4) Now, there are a few points you should keep in mind while shifting the image by tx and ty values.
