PdfFileWriter | PDF File Writer C # class library PdfFileWriter Version | Document Editor library

I am very new to python. I have the following code that takes user input from a GUI for the "x" and "a" variable. The goal is to have it open each .pdf in the directory perform the modifications, and save over itself. Each pdf in the directory is a single page pdf. It seems to work however, the newly saved file is corrupted and cannot be opened.

I am trying to parse a number from an image. Here's an example of the images

I tried first to extract all the text to have a look at the final result but the code didn't recognize the desired number This is my try

I'm trying to merge two pages one from reportlab that has the text I wish and another one is my source pdf

But when I merge those two pages, my text is rotated 90 degree

Pdf created using Report lab -> Overlay Created using Reportlab

when Merged with Source pdf -> Source Pdf

Code that I have Used :

So I tried writing a code where when I insert the address of a pdf file into my code below,It extracts only the first 3 pages of the pdf and save it as(nameofthepdf_subset.pdf). But now I want to this to happen to every Pdf in the folder, How do I make it happen?

This my code which I got from a YouTube channel:

I have multiple pdf files that I want to extract a group of specific pages from where each set of pages is different for each pdf file. I have created a dictionary with the keys as the pdf file name and the values as the list of pages to be extracted from each pdf file (shown as key). I intend to extract the given pages from the associated pdf file and write them all to one new pdf file so that I can do data extraction on this final file. I have tried PyPDF4 as well as FPDF but no joy as yet as it gives me either a large pdf with blank pages or a pdf with just 1 or 2 pages extracted or error that the pdf object cannot be found. I am hoping to get some guidance on where I am going wrong with my approach. Below is my code:

I am attempting to create a function that combines pdf files into a single file. I am attempting to take a dictionary that is constructed as follows:

What i'm to do is to read all the pdf file from selected directory, then i do for loop for all the pdf that i get from the directory. and then i protect the file with given password.

let say i have 5 file to be protect with given password. first file protected successfully with correct content. but the second file until five file content are merged with the previous file content.

example in second file there is a first file content and second file content. in the third file content there is first file, second file and third file content.

This is the code :

I want to change the color of the rectangle contourn created with addLink command of PyPDF2 from black to blue but I can't find documentation about it and I couldn't find any solution yet.

I am trying to put a watermark on a pdf but when I run the code it does nothing , It does not create the output file what did I missed?
