What code have you written so far? People on this forum will help, but will not write code for you if you have not done any yourself. Show us what you have done and we can go from there.
You have made a start by identifying a method to use for alignment, but what do you have to support that idea? What other methods have you tried?
Just asking for a solution without any real sign of input from you is not how to get help.
Regards
