问题 I used chrome to convert a webpage into Pdf using save as pdf option. Now the problem is that when I extract the data from it using PyPDF2, it shows Null whereas it works on other pdf files easily. I know that I can extract data directly from the website but I want to understand why this is not working. It shows the correct number of pages but when I extracttext(), it shows nothing. Does anyone know what is the problem? The link to the page is https://en.wikipedia.org/wiki/Rapping. I

问题 I am using PyPDF4 to create an offline-readable version of the journal "Nature". I use PyPDF4 PdfFileReader to read the individual article PDFs and PdfFileWriter to create a single, merged ouput. The problem that I am trying to solve is that the page numbers of some issues do not start at 1, for example, issue 7805 starts with page 563. How do I specify the desired /PageLabels in the document catalog? for pdf_file in pdf_files: input_pdf = PdfFileReader(open(pdf_file, 'rb')) page_indices =

问题 I'm trying to automate merging several PDF files and have two requirements: a) existing bookmarks AND b) pagelabels (custom page numbering) need to be retained. Retaining bookmarks when merging happens by default with PyPDF2 and pdftk, but not with pdfrw. Pagelabels are consistently not retained in PyPDF2, pdftk or pdfrw. I am guessing, after having searched a lot, that there is no straightforward approach to doing what I want. If I'm wrong then I hope someone can point to this easy solution.

问题 I'm creating a python script to edit text from PDFs. I have this Python code which allows me to add text into specific positions of a PDF file. import PyPDF2 import io from reportlab.pdfgen import canvas from reportlab.lib.pagesizes import letter import sys packet = io.BytesIO() # create a new PDF with Reportlab can = canvas.Canvas(packet, pagesize=letter) # Insert code into specific position can.drawString(300, 115, "Hello world") can.save() #move to the beginning of the StringIO buffer

问题 I'm editing a PDF file with pyPDF2. I managed to generate the PDF I want but I've yet to rotate some pages. I went to the documentation and found two methods: rotateClockwise and rotateCounterClockwise , and while they say the parameter is an int , I can't make it work.
