pdf2image | A utility for converting pdf to image and base64 format | Document Editor library

I am trying to convert pdf to an image using the following code

I am trying to deploy my docker container on AWS Lambda. However, I use pdf2image package in my code which depends on poppler. To install poppler, I need to insert the following line in the Dockerfile.

I wanted to make a Python program that converts PDFs to PNGs, but when I ran the code it showed an error for some reason.

Here's my code:

in the code i'm converting multiple 1-page PDFs into PNG Format. The converting itself works out well with cv2 but sadly many documents (PDFs) names contain german umlauts (ä,ö,ü) and the PNGs end up having special characters.

Example: After converting the PDF (lösung_122.png) to PNG, it looks like this "lösung_122.png". It should be loesung_122.png.

I would like to replace all these characters (ä,ö,ü) in the document titles with ae, oe, ue.

How can i adjust my code to archieve this? What options do i have? Maybe theres a way to rename the documents (PDFs) before converting them?

Using PyQt5 I am viewing an image in a QGraphicsView. I want to be able to zoom in/out while pressing ctrl and using the mouse wheel. I have this working, however if the image is too large, and there are scroll bars, it ignores the zoom functionality until you scroll to the top or bottom.

How can I fix this to where it does not scroll when ctrl is pressed, while allowing it to zoom in/out.

I need a simple python library to convert PDF to image (render the PDF as is), but after hours of searching, I keep hitting the same wall, I find libraries like pdf2image python library (and many similar ones), which depend on external applications or wrap command-line tools.

Although there are workarounds to allow using these libraries in serverless settings, they all would complicate our deployment and require creating the likes of Execution Environments or extra lambda layers, which will eat up from the small allowed lambda size.

Is there a self-contained, independent mechanism (not dependent on command-line tools) to allow achieving this (seemingly simple) task?

Also, I am wondering, is there a reason (licensing or patents) for the scarcity of tools that deal with PDFs (they are mostly commercial or under strict AGPL licenses)?

I have this simple code that takes a PDF, converts the pages into images and then displays them inside a ttk Notebook. This works only if I do not use a function to load the PDF. However this is part of a much larger program that lists many PDF forms; therefore, I need a function to load the PDF. It looks like the PDF is loading but its all grey.

I don't know what I am doing wrong here. I looked around but couldn't find anything related to the exact problem I am running into. I do want to use this method of displaying PDF forms because it's the one that looks the best when the PDF forms are filled in with information.

Please bear with me because I just started programming a month ago. There might be more than one thing wrong with my code.

I've found some guides online on how to make a PDF searchable if it was scanned. However, I'm currently struggling with figuring out how to do it for a multipage PDF.

My code takes multipaged PDFs, converts each page into a JPG, runs OCR on each page and then converts it into a PDF. However, only the last page is returned.

I am working on a project to extract text from a bunch of scanned PDF's. I am following this tutorial. One of the first steps involves importing modules. I'm having some trouble importing 'pdf2image'. For context, I'm using a Conda environment called, "textExtractor" in VS Code's Python terminal. I checked if pdf2image was installed by running "Conda list" and it looks to be installed. However, when I run the python script I get an error saying,

(textExtractor) C:\Users\mhiebing\Documents\GitHub_Repos\MonthlyStatsExtract>C:/Users/mhiebing/Anaconda3/python.exe c:/Users/mhiebing/Documents/GitHub_Repos/MonthlyStatsExtract/PDF_to_Image.py

Traceback (most recent call last): File "c:/Users/mhiebing/Documents/GitHub_Repos/MonthlyStatsExtract/PDF_to_Image.py", line 1, in from pdf2image import convert_from_path, convert_from_bytes

ModuleNotFoundError: No module named 'pdf2image'

Below is a screenshot showing pdf2image and the error:

Any idea what's going wrong?
