如何在Python中检测PDF文档中的旋转页面?

问题描述:

给出具有多个页面的PDF文档,如何检查给定页面是否旋转(-90、90或180º)?最好使用Python(pdfminer,pyPDF)...

Given a PDF document with multiple pages, how to check if a given page is rotated (-90, 90 or 180º)? Preferable using Python (pdfminer, pyPDF) ...

更新:扫描页面,并且大部分页面由文本组成.

UPDATE: The pages are scanned, and most of the page is composed by text.

我只是在PyPDF2中使用了页面的/Rotate属性:

I used simply /Rotate attribute of the page in PyPDF2:

 pdf = PyPDF2.PdfFileReader(open('example.pdf', 'rb'))
 orientation = pdf.getPage(pagenumber).get('/Rotate')
