Idea for tutorial

[portfedh]

Hi!

I just made a short blog post of a snippet i use a lot with fpdf2.

Its a script to merge odd and even pdf pages.

I use it when I scan files with lots of pages on a scanner that can only scan one side at a time.

I think its simple enough that it might be a good addition to the fpdf2 tutorial section.

Here is the blog post.

Let me know what you think!

from PyPDF2 import PdfFileReader, PdfFileWriter

While your blog post instructs to install fpdf2, what your code actually uses is an entirely different package...

Thank you for pointing that out!

I made the same script with several packages and uploaded the wrong one.
I'll correct the post and post again for you to review.

I double checked, and found the reason I ended up switching in to PyPDF2.

In FPDF2, I found this tutorial.
https://pyfpdf.github.io/fpdf2/ExistingPDFs.html

I tried to work on it, but even after installing, i got:

ModuleNotFoundError: No module named 'pdfrw'

Sorry about that. I still think its a good idea, but I couldn't get it to work.
I'll change the post to reflect the right package. : (

In FPDF2, I found this tutorial. https://pyfpdf.github.io/fpdf2/ExistingPDFs.html

At the very top of that page, it explains:

This page provides several examples of doing so using pdfrw, ...

So why didn't you just install the pdfrw package at that point?

Of course, if you only want to shuffle pages in existing PDFs around, then using a full fledged PDF generator like fpdf2 is overkill in the first place.
Each one of pdfrw or PyPDF2 will do that just fine on its own.

I did try to install using:
pip install pdfrw

And also the way the tutorial mentions in fpdf2:
https://pyfpdf.github.io/fpdf2/ExistingPDFs.html
pip install git+https://github.com/PyFPDF/pdfrw.git@addpage_at_index

But when running the script I kept getting an error as if the library was not installed. I didn't really get why.

I agree, this is a very simple thing, and its overkill.
