Retrieve a 512 x 512px icon for an iOS app
#!/usr/bin/ruby
# encoding: utf-8
#
# Updated 2017-10-25:
# - Defaults to large size (512)
# - If ImageMagick is installed:
# - rounds the corners (copped from @bradjasper, https://github.com/bradjasper/Download-iTunes-Icon/blob/master/itunesicon.rb)
# - replace original with rounded version, converting to png if necessary
#
# Retrieve an iOS app icon at the highest available resolution
# All arguments are combined to create an iTunes search
# The icon for the first result, if found, is written to a filename
# based on search terms
#
# If ImageMagick is installed (available through Homebrew), rounded
# corners will be added and a transparent PNG will be output.
#
# example:
# $ itunesicon super monsters ate my condo
#
# Use size param ~s/~small/~m/~medium/~l/~large to specify size:
# $ itunesicon super monsters ate my condo ~small

The ImageMagick steps are not working for me anymore. I'm on Big Sur. I've tried reinstalling ImageMagick with Homebrew. Do I need to do something to make it available to this Automator workflow?

I noticed I wasn't getting rounded corners anymore, but hadn't had time to look into it. I don't have an answer offhand, but will try to dig in next time I have some free time (new job).
