- Used and tested on MacOS. I presume it works fine on Linux. However, this was not checked.
- I liked tinkering with Bash for this.
- Made in PyCharm with BashSupport.
Needs the ImageMagick package for the convert command. I installed it with Homebrew:
brew install imagemagick
For Linux you could try using Linuxbrew or some other alternative to Homebrew.
