I set the app to take shot anytime pixels significantly change. Your screen clock advancing will not trigger a shot... whereas the Kindle app advancing to next page will. When done, yea you can just leave them in a directory and read with an image viewer (nomacs works great and has auto advance slideshow function), or you can combine the png snapshots into a pdf using Image Magick on linux.
FYI, there is a file format that is meant for this stuff (pages that are images with a searchable textual layer: intended for archival of electronic copies of paper books by people like the Internet Archive who do a massive amount of archival work of this sort). Look for 'DjVu'. It's *massively* more space-efficient than storing individual pages in a PDF.
