I’ve updated iTunesIcon, my little Automator App for grabbing the high res versions of iOS and MAS app icons directly from iTunes. Version 2.2 had proven a bit buggy after some minor search API changes.
Changes
Defaults to 512px size now, unless ~s (small, 60px) or ~m (medium, 100px) are specified in the search string
If ImageMagick is installed, it now rounds the corners of iOS icons automatically (code inspired by Brad Jasper)
Replaces original download with rounded version, converting to png if necessary
Other minor cleanups and improvements
Oh yeah, and a new icon which, if I may say so, is delightful
See the iTunesIcon project page for more info on installing ImageMagick. It works just fine without it, but the rounded corners are a nice touch.
