eBook layout

This tab contains all the layout options for eBooks.

OpenComic supports both reflowable and fixed-layout EPUB files, including EPUBs that use right-to-left or vertical reading directions.

EPUB features​

  • Fixed-layout EPUB support.
  • Right-to-left EPUB support.
  • Vertical EPUB support.
  • Option to force left-to-right reading when you want to override the book direction.
  • Text selection support.
  • Clickable link support.
  • Option to extract document images for workflows that need page images instead of the EPUB container.

Rendered EPUB files are cached to improve loading performance when reopening the same book.

If you want to use the AI Tools with an EPUB, extracting document images is required because the AI workflow operates on images.
