Bookmark file format

Example:

		2.1.1 SubTitle 2.1.1 4.5
	2.2 SubTitle 2.2 7.3

The hierarchical structure of the bookmarks is controled by the Tab numbers at the begining of each line.

|bookmark title| and |page ratio| must be separated by white spaces.

|page ratio| is a decimal number, the integer part represents the page numberof the bookmark, the fractional part represents the location of the bookmark: .0 indicates that the bookmark is on the top of the page, .99 indicates that the bookmark is almost on the bottom of the page.

Usage

Typical usage of the file is:

import sys
sys.path.append('C:/PyPDF2') # add PyPDF2 path to system path
from PdfBookmark import PdfBookmark
bm = PdfBookmark('a0.pdf')
bm.exportBookmark('test.bm')

Then view and modify the bookmark file as you need. When you've finished your modification, you can use the following code to create new bookmarks in the PDF.

bm.importBookmark('test.bm')

Another PDF file with the name *PDFFILENAME*_bookmark.pdf will be created by default, you can also provide a PDF file name when you call the function importBookmark

bm.importBookmark('test.bm', 'a1.pdf')
