[Metadata Writer Plugin] Embed PDF ToC

[rexylic]

Add table of contents to PDFs using pypdf.

A table of contents can be specified either in a plain-text file or by adding entries to a table in Calibre. Both formats are equivalent. The plain-text file looks like this:

Preface vi
Introduction 1
Chapter 1 3
    1. A story 4
    2. Another story 7
        2.1 Anecdote 9
Chapter 2 20

The table of contents is saved in the book's data folder, and can be edited, re- and un-embedded at any time.

A limited clean-up function using ghostscript is available through the dialog window. I've encountered cases where the ToC shows up in my PDF viewer but not on my e-reader; the clean-up function fixes this.

This is my first time posting on mobilereads. Please let me know if I'm breaking any rules or how I can improve my posts. Thanks!

Installation and usage
Download the zip and load it via "load plugin from file". The "Embed ToC" action will be available in interface preferences.

Very cool! It's great that the plugin allows setting negative page offset.
