Command line graphics: How to use your terminal to process tons of images, extract data from photos, make GIFs and movies...and more

  • Event: 2016 CAR Conference
  • Speaker: Jon Keegan of The Markup
  • Date/Time: Saturday, Mar. 12 at 3:30pm
  • Location: Penrose
  • Audio file: Only members can listen to conference audio

Some of the most powerful tools for creating visuals and working with images lie hidden in your terminal. We'll do an overview of some of these amazing (FREE!) tools – such as ImageMagick and ffmpeg – and see some real world techniques for working with large collections of images, and how I use these tools in my projects at WSJ. Some of the things we'll cover: make a timelapse video from sequential images, extract and save metadata embedded in photos, create image quilts, and build animated GIFs from videos.
