ty, as a noob I would add
#place script in $ProjectRoot/resources/ and run with sh iconify.sh
#requires the convert command line tool, available from brew install imagemagick on macOS

Thanks for making & sharing.

It wasn't immediately obvious to me, but this will only run on OSX due to the sips command. Likely there is a Linux equivalent, but I'm not skilled enough to know what it is.

Look at convert from imagemagick. If you can get that working please post your solution because I think others wouldn value it too.
