Ah, yes. The classic “works on my device” argument.

Edit: from testing with zbarimg on my laptop: Basic, Camo, Neon (inverted), Glass, Blocks, Alien all seem to work reliably. Not sure what the problem is with some others, but maybe they’ll also work with some tweaking (Mondrian seems simple enough! maybe contrast issues?)

  wl-paste -t image/png | zbarimg -
  # macOS:
  pngpaste | zbarimg -

Edit 2: for codes that will definitely be scanned using a camera [1], some styles can work because phone camera isn’t perfect. E.g. if you slightly blur Dots, it works with zbarimg, which also means it would work if you slightly move around your phone.
