If you are creating a sister app on MacOS you'll need to add another 11 to that number... and you probably want them to be consistent but different (Mac icons will want to have their mask pre-applied too).

This kind of task is one of the major reasons I created DrawDown. Although I use the interactive Mac App in this article, the resultant script can be used with the free command line version, it's just nice to be able to see the output next to the script.

Getting Ready

We are going to need a few assets for our icon, so I've just organised my DrawDown and the assets it uses into a folder. By default the search path is the directory the script is in, so this saves a little bit of set-up and also makes it a bit more portable. All of these resources are available here.
