A PDF can be reflowed without reconstructive processing only if a PDF was generated as a Tagged PDF [1] and if the viewer supports reflowing. [1]: Essentially a PDF with its own EPUB inside it, but unlike just having an attached EPUB, there is a map between the page layout of the PDF and the tags. There are implementations of reconstructive reflowing that infer the layout block structure and reading order and can reflow a two column paper into a single column. |
