Would it be possible for Xojo to automatically generate the icons needed for iPhone/iPad apps?
I wrote a little tool to do this. I give it a 2048x2048 png, and it outputs all the needed icons. I then drag them into to icon page in the app. This has worked well as I try to make nice “blocky” icons.
This would be optional: If you need to hand-craft the icons, that could still be done.
That’s a nice idea but not really the optimal way to make icons. Just scaling will inevitably get you a blob of mud at the smallest resolutions.
Usually you have a highly detailed icon at 1024x1024 and each smaller icon has less and less detail (and possibly removed elements) so they don’t get blurry.
