kj-slidepacker

to be used with exports from sent-web, LaTeX Beamer, or any other source of PDF presentations.

converts a .pdf presentation into a "fake" .pptx by rendering each page as an image and pasting it onto a blank slide.

output slides are not editable, this is intentional.

the goal is just to get a pdf into pptx format for corporate compliance purposes (e.g., when someone absolutely NEEDS a .pptx and would go crazy if the file is not sent with an extension that says • P P T X).
