PyPDF2 'PageObject' 未定义

Question

I've been using PyPDF2 (version 1.26.0) to create new PDFs with no problems so far: rotating, cropping pages and more.

For some reason, the second line throws an error:

from PyPDF2 import PdfFileWriter, PdfFileReader

page = PageObject.createBlankPage(100, 100)

Being the error the following:

NameError: name 'PageObject' is not defined

Why could this be happening?

Answer 1

It seems like you aren't importing the PageObject class. Python only has access to the things you import. Please add this to the top of your file:

from PyPDF2.pdf import PageObject

Answer 2

I found another way to achieve what I wanted, using PdfFileWriter's "addBlankPage"

from PyPDF2 import PdfFileWriter, PdfFileReader
output = PdfFileWriter()
output.addBlankPage(100, 100)
