Adding bookmarks in Acrobat with JavaScript?

[Doitsu]

Originally, I had planned to use a JavaScript script to add missing TOC bookmarks, but then I found a great Open Source Java program that allows TOC boookmarks to be added from a text file: JPdfBookmarks

To use it you'll have to create a bookmarks text file that looks at a bare minimum like this (bookmark title/page number):

Chapter 1/1
Chapter 2/10
Chapter 3/20

Then all you have to do is:
1. Open the .pdf file with JPdfBookmarks.
2. Click the Load Bookmarks from a text file... button and select your bookmarks text file.
3. Save the .pdf file.

For more information, see the program's Wiki page.

The only downside is that JPdfBookmarks is a bit slow. If you have an older machine or a very large .pdf file, it might take some time until all bookmarks are added.
