正如@theta指出的那样，“根据轮廓分割pdf ”具有提取页码所需的代码。如果您觉得这很复杂，我复制了一部分代码，该代码将页面ID映射到页面编号并使其成为函数。这是一个打印书签o [0]的页码的工作示例：
from PyPDF2 import PdfFileReader
def _setup_page_id_to_num(pdf, pages=None, _result=None, _num_pages=None):
if _result is None:
_result = {}
if pages is None:
_num_pages = []
pages = pdf.trailer["/Root"].getObject()["/Pages"].getObject()
t = pages["/Type"]
if t == "/Pages":
for page in pages["/Kids"]:
_result[page.idnum] = len(_num_pages)
_setup_page_id_to_num(pdf, page.getObject(), _result, _num_pages)
elif t == "/Page":
_num_pages.append(1)
return _result
# main
f = open('document.pdf','rb')
p = PdfFileReader(f)
# map page ids to page numbers
pg_id_num_map = _setup_page_id_to_num(p)
o = p.getOutlines()
pg_num = pg_id_num_map[o[0].page.idnum] + 1
print(pg_num)
@theta可能为时已晚，但可能会对其他人有所帮助：） btw我关于stackoverflow的第一篇文章，所以请问如果我不遵循通常的格式
如果您希望在页面上获得书签的确切位置，这将使您的工作更加轻松：
from PyPDF2 import PdfFileReader
import PyPDF2 as pyPdf
def _setup_page_id_to_num(pdf, pages=None, _result=None, _num_pages=None):
if _result is None:
_result = {}
if pages is None:
_num_pages = []
pages = pdf.trailer["/Root"].getObject()["/Pages"].getObject()
t = pages["/Type"]
if t == "/Pages":
for page in pages["/Kids"]:
_result[page.idnum] = len(_num_pages)
_setup_page_id_to_num(pdf, page.getObject(), _result, _num_pages)
elif t == "/Page":
_num_pages.append(1)
return _result
def outlines_pg_zoom_info(outlines, pg_id_num_map, result=None):
if result is None:
result = dict()
if type(outlines) == list:
for outline in outlines:
result = outlines_pg_zoom_info(outline, pg_id_num_map, result)
elif type(outlines) == pyPdf.pdf.Destination:
title = outlines['/Title']
result[title.split()[0]] = dict(title=outlines['/Title'], top=outlines['/Top'], \
left=outlines['/Left'], page=(pg_id_num_map[outlines.page.idnum]+1))
return result
# main
pdf_name = 'document.pdf'
f = open(pdf_name,'rb')
pdf = PdfFileReader(f)
# map page ids to page numbers
pg_id_num_map = _setup_page_id_to_num(pdf)
outlines = pdf.getOutlines()
bookmarks_info = outlines_pg_zoom_info(outlines, pg_id_num_map)
print(bookmarks_info)
elif type(outlines) == pyPdf.pdf.Destination:
title = outlines['/Title']
result[title.split()[0]] = dict(title=outlines['/Title'], top=outlines['/Top'], \
left=outlines['/Left'], page=(pg_id_num_map[outlines.page.idnum]+1))
