Question

我想采用多页pdf文件，并在每页创建单独的pdf文件。

我已下载reportlab并浏览了文档，但似乎是针对pdf生成。我还没有看到任何关于自己处理PDF文件的事情。

在python中有一种简单的方法吗？

Answer 1

from PyPDF2 import PdfFileWriter, PdfFileReader

inputpdf = PdfFileReader(open("document.pdf", "rb"))

for i in range(inputpdf.numPages):
    output = PdfFileWriter()
    output.addPage(inputpdf.getPage(i))
    with open("document-page%s.pdf" % i, "wb") as outputStream:
        output.write(outputStream)

等

Answer 2

PyPDF2软件包使您能够将一个PDF拆分为多个PDF。

import os
from PyPDF2 import PdfFileReader, PdfFileWriter

pdf = PdfFileReader(path)
for page in range(pdf.getNumPages()):
    pdf_writer = PdfFileWriter()
    pdf_writer.addPage(pdf.getPage(page))

    output_filename = '{}_page_{}.pdf'.format(fname, page+1)

    with open(output_filename, 'wb') as out:
        pdf_writer.write(out)

    print('Created: {}'.format(output_filename))

Answer 3

我在这里错过了一个解决方案，您将PDF分为由所有页面组成的两部分，因此如果有人在寻找相同的内容，我会附加我的解决方案：

from PyPDF2 import PdfFileWriter, PdfFileReader

def split_pdf_to_two(filename,page_number):
    pdf_reader = PdfFileReader(open(filename, "rb"))
    try:
        assert page_number < pdf_reader.numPages
        pdf_writer1 = PdfFileWriter()
        pdf_writer2 = PdfFileWriter()

        for page in range(page_number):
            pdf_writer1.addPage(pdf_reader.getPage(page))

        for page in range(page_number,pdf_reader.getNumPages()):
            pdf_writer2.addPage(pdf_reader.getPage(page))

        with open("part1.pdf", 'wb') as file1:
            pdf_writer1.write(file1)

        with open("part2.pdf", 'wb') as file2:
            pdf_writer2.write(file2)

    except AssertionError as e:
        print("Error: The PDF you are cutting has less pages than you want to cut!")

我知道该代码与python不相关，但是我想发布这段简单，灵活且效果惊人的R代码。 R中的PDFtools软件包在轻松拆分合并的PDF方面非常了不起。

library(pdftools) #Rpackage
pdf_subset('D:\\file\\20.02.20\\22 GT 2017.pdf',
           pages = 1:51, output = "subset.pdf")

用python将多页pdf文件拆分成多个pdf文件？
