Does this mean the text only pdf page is transformed into an image that covers the full page, but the text is still under there. So, any machine based extraction would still get the text, but would probably loose all the bounding box information and regular users cannot just use their mouse to select text anymore?
Seems true and really wish the project included some sample PDF output.
My Text to Speech app uses bounding box to display what text in PDF is being read and would not work well PDF's from this project.
