A quick example of needed calculations. I only made the math for width (X). Height (Y) is up to you.
You are going to need to do some calculations to compare your e. PageX and e. PageY to window width/height and width/height of your preview element to see if it will fit the window or not.
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.
