I am totally new to this and am planning to write my first program with C++ that adds two images. I have seen alot of resources on net that tells technique of doing soo and they look easy to be implemented. But i am not sure if they are the best and most efficient way of doing it. So, my question to all you graphics programmer is that can you guide me towards some reliable resources on that matter. Also, can you give me some hints that which parameters should i take most care of to efficiently implement the program . Thanks
