The screenshots below are unchanged copies of real PDFBook 1.1.0 captures used on the official website, pdfbook.app. The example books are demonstration documents.

These are application captures, not generated interface mockups. Keep the files local to this repository so the README and documentation do not depend on an external screenshot service.
Only English and Japanese screenshots are currently provided. Other README translations label their screenshots as the English interface; they do not imply that the captured screens are localized.
