This ASCiinema cast features a competition in PDF processing. See how different PDF tools score when it comes to extract a text snippet containing source code from a specific page!

(The cast may at certain spots be progressing too fast for you to follow closely. Please make use of the Pause button at the lower left corner if you need more time to read+understand the details of the screen contents. You can also scroll back if needed.)

The combatants are:

Apple Mac OS X Preview.app
Adobe Reader XI
Acrobat Professional XI
Evince (Poppler-based)
Chrome Web Browser with native, built-in PDF renderer PDFium
Chrome Web Browser with external PDF renderer PDF.js
Poppler-based Command Line Tool pdftotext
