If I have standard document, a pdf for example, that is rectangular (like a sheet of paper is rectangular), and the aspect ratio is made to fill the screen of a previous generation iPad Pro, how will it now display on the new iPad Pro which has rounded corners? Will it expand slightly to fill the screen thus cropping the corners and edges? Or will it leave some sort of margin on all sides so the square corners of the document just touch the rounded corners of the screen? And photos as well, which are also rectangular in format. Will they get cropped to fill screen, or have margins? It’s a bit of quandary for me, as a lot of my graphic design work is specifically formatted to fit full screen. I don’t quite understand the reason for rounded corner screens. It may look slick as an industrial design thing, but it creates a dead area on the display that really isn’t usable... so what’s the point?
