Dynamic GIF on Github

  1. How is the GIF embedded in the markdown?

  2. Where can I see it?

  3. TravisCI
  4. The only .png match points to Repositories#show
  5. repo = service(:find_repo, params).run -> line 31 in the repo controller, this must be how it is done.

  6. How do we dynamically generate a png in ruby


  • MagickTitle.say("Hello") builds a PNG that predictably says “Hello”
  • the gifs on github are 13 pixels tall

  • svg image url

  • Moveable ink
