通过旋转和平移将两个PDF文件合并到一个页面中

我有两个PDF,我需要合并成一个单一的,1宽2高的尺寸。如果你听说过一个帐篷卡,这是生产一个帐篷卡PDF。

translated_page 外场。

#!/usr/bin/python3

import PyPDF2

from PyPDF2.pdf import PageObject

front_reader = PyPDF2.PdfFileReader(open('front.pdf', 'rb'))
front = front_reader.getPage(0)

back_reader = PyPDF2.PdfFileReader(open('back.pdf', 'rb'))
back = back_reader.getPage(0)

tent_height = front.mediaBox.getHeight() + back.mediaBox.getHeight()

translated_page = PageObject.createBlankPage(None, back.mediaBox.getWidth(), tent_height)
# translated_page.mergeScaledTranslatedPage(back, 1, 0, front.mediaBox.getHeight())
# translated_page.mergeRotatedTranslatedPage(back, 180, 0, 0)
translated_page.mergeRotatedPage(back, 180)
translated_page.mergePage(front)

writer = PyPDF2.PdfFileWriter()
writer.addPage(translated_page)

with open('out.pdf', 'wb') as outfile:
    writer.write(outfile)

这是上面提到的文件。我错过了什么?
