So I cannot find any resources on how this works, I have 3 device resolutions 1x 2x and 3x. Lets assume I an app that generates images of size 640 by 640.
If my uiimage is 64 by 64 points, that means that I have to provide 3 specific resolutions of that thumbnail. So a 64by64 a 128by128 and and 192by192 ?
Meaning that I have to find a 192 by 192 image or larger than that and scale it down in some manner to ensure that it is properly rendered ? So I would take my 640 by 640 and scale it down to those 3 resolutions so they would be rendered correctly for each screen resolution ?
if someone can clarify this it would be great thank you!
