Today I learnt - Image Magick scripts

I was generating logos for Git Notify’s Chrome Extension with the help of GoSpaces Tools. I have got a generic one in a decent sized banner. I had to crop off in the centre.

imagemagick to the rescue. but the args? A simple Google search solved it.

Fred Weinhaus has put together lots of Image Magick scripts. One I was looking was to crop in the middle is called squareup.

  • What you get right, nobody mentions it.
  • What you get wrong, people bitch about.
  • What is difficult to understand you have to explain to people over and over again.
