OK, firstly, yeah I know it's not exactly an iTouch programming question, but this forum doesn't have an iTouch designing section, so... Moving on, I'm putting together a couple of icons for a colleague and I've done the designs and they're now finished and so all I need to do now is export them as PNGs in the correct sizes, etc. As I understand it, when I create the PNGs, there's no need for me to include any rounded corners with alpha-transparency, etc. as Apple add this themselves. OK, so that's fine, but the designs I've done make use of an inner-glow effect which follows the icon's rounded corners. So even if I export a flat square-cornered icon, I still need to know the corner radius of the icon so that I can set my inner-glow effect to follow the rounded corner that Apple will add afterwards. For the initial designs, I've worked on my own assumptions and guesstimates of what the corner radius is, but for the final product, I'd really like to be absolutely 100% pixel-perfect. So I'm asking if anyone here knows precisely what the corner-radius of the icons is? Now that's going on the knowledge I have that I need to create one uber-large icon at 512x512 (that Apple will scale down and use at several sizes on the App-Store) and one small icon at 57x57 that will be used on the iPhone / iPod itself. Is this also correct? So what I'd really need to know are BOTH corner-radiuses ("radii"?) for these two icons. Any precise confirmed information on this is appreciated. Thanks.
