Maintaining aspect ratio?

Yes, it's possible if the source image is already wide enough. If it's not wide enough there isn't enough data to crop and if you wanted to maintain aspect ratio, you'd need to scale the image up before the crop.

To properly maintain aspect ratio you should use GCD.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
