Hello,
Apparently, since neither Calibre nor Abbyy can use a PDF's bookmarks to split chapters, I'm thinking of 1) exporting chapters into independent PDFs, 2) convert them into individual EPUBs, and 3) join them into a single EPUB file.
Code:
cpdf.exe -split-bookmarks 0 input.pdf -o out%%%.pdf
Is there an open-source, preferably CLI application, that can join EPUBs into a coherent file?
Thank you.
