python - 中途拆分 PDF 页面并重新组合？

Question

我现在没有足够的声誉分数来回答我发现的问题 - 如何使用 python 将 pdf 页面分成两半并重新组合以进行进一步处理..

#!/usr/bin/env python

'''

Chops each page in half, e.g. if a source were
created in booklet form, you could extract individual
pages, and re-combines it
'''
from PyPDF2 import PdfFileWriter,PdfFileReader,PdfFileMerger
#split left
with open("docu.pdf", "rb") as in_f:
    input1 = PdfFileReader(in_f)
    output = PdfFileWriter()

    numPages = input1.getNumPages()

    for i in range(numPages):
        page = input1.getPage(i)
        page.cropBox.lowerLeft = (60, 50)
        page.cropBox.upperRight = (305, 700)
        output.addPage(page)

    with open("left.pdf", "wb") as out_f:
        output.write(out_f)
#split right
with open("docu.pdf", "rb") as in_f:
    input1 = PdfFileReader(in_f)
    output = PdfFileWriter()

    numPages = input1.getNumPages()

    for i in range(numPages):
        page = input1.getPage(i)
        page.cropBox.lowerLeft = (300, 50)
        page.cropBox.upperRight = (540, 700)
        output.addPage(page)

    with open("right.pdf", "wb") as out_f:
        output.write(out_f)

#combine splitted files
input1 = PdfFileReader(open("left.pdf","rb"))
input2 = PdfFileReader(open("right.pdf","rb"))
output = PdfFileWriter()
numPages = input1.getNumPages()

for i in range(numPages):
    l = input1.getPage(i)
    output.addPage(l)
    r = input2.getPage(i)
    output.addPage(r)

with open("out.pdf", "wb") as out_f:
    output.write(out_f)

注意：裁剪参数是特定于您的 PDF 的，因此请在执行程序之前检查它。

进一步：现在，您可以使用此文档轻松提取文本，而无需将列相互合并 - 提取混乱..
