用Python缩小和合并PDF [英] Shrink and merge PDFs in Python

问题描述

我正在尝试将两张A4 PDF页面缩小并合并为一张A4页面，以便在需要时将其合并；

I'm trying to shrink and merge two A4 PDF pages into one A4 page so that if I had;

 _____        _____        
|     |      |     |
| p1  |      | p2  | 
|     |      |     |
|_____|      |_____|

我会得到；

 _____             
| p1  |    
|.....| 
| p2  |  
|_____|      

作为新的PDF，在该页面上有两张A5尺寸的页面.类似于您可能在纸上每页打印两页.

As a new PDF, with two A5 sized pages on that one page. Similar to how you might print two pages per page on paper.

我已经研究了pyPDF(http://pybrary.net/pyPdf/)ReportLab(http://www.reportlab.com)，但似乎找不到如何缩小和合并这样的内容.

I've looked into pyPDF (http://pybrary.net/pyPdf/) ReportLab (http://www.reportlab.com) but I can't seem to find how to shrink and merge like this.

有任何提示吗?

谢谢！

推荐答案

pdfnup具有此功能(http://pypi.python.org/pypi/pdfnup)#

pdfnup has this functionality (http://pypi.python.org/pypi/pdfnup)#

例如

from pyPdf import PdfFileWriter, PdfFileReader
from pdfnup import generateNup

output = PdfFileWriter()
input1 = PdfFileReader(file("in.pdf", "rb"))

page1 = input1.getPage(0)
page2 = input1.getPage(1)

output.addPage(page1)
output.addPage(page2)

outputStream = file("out.pdf", "wb")
output.write(outputStream)
outputStream.close()

generateNup("out.pdf", 2)
