How do I convert a multiple paged PDF into a PNG image per pdf page in Python

Asked 2022-Apr-15 at 17:47

Amateur Python developer here. I'm working on a project where I take multiple PDfs, each one with varying amounts of pages(1-20ish), and turn them into PNG files to use with pytesseract later.

I'm using pdf2image and poppler on a test pdf that has 3 pages. The problem is that it only converts the last page of the PDF to a PNG. I thought "maybe the program is making the same file name for each pdf page, and with each iteration it rewrites the file until only the last pdf page remains" So I tried to write the program so it would change the file name with each iteration. Here's the code.

Your code is only outputting a single file as far as I can see. The problem is that you have a typo in your code.

The line

file_number =+ 1

is actually an assignment:

file_number = (+1)

This should probably be

file_number += 1

Asked 2022-Mar-30 at 20:10

I'm trying to create a PDF preview for my PDF files, but I don't know where to start, I'm using poppler gem on Ruby on Rails.

The app is giving me this message: "ActiveStorage::UnpreviewableError in Tasks#show"

So I'm not understanding where should I need to declare the preview

Looking on google I found several sites with methods, but I don't know where to add this code, I've tried by creating a new folder on the app directory, but this didn't work.

In activestorage documentation says about requirements to use this feature.

libvips v8.6+ or ImageMagick for image analysis and transformations
ffmpeg v3.4+ for video previews and ffprobe for video/audio analysis
poppler or muPDF for PDF previews

Check if in your environment has the requirements

cv2 rename ä ö ü to ae oe ue

Asked 2021-Oct-26 at 15:04

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 "lÃ¶sung_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?

ANSWER

Answered 2021-Oct-11 at 09:08

I found the solution. For it to not throw the error, I had to change my file_get_contens a bit, I did this by doing the following:

$file = rtrim(file_get_contents($f->file_current, FILE_TEXT)); $file = mb_convert_encoding($file, 'UTF-8', mb_detect_encoding($file, 'UTF-8, ISO-8859-1', true));

and then put $file in to ->set('file', $file) instead of ->set('file', file_get_contents($f->file_current))

So converting it from one encoding to another seemed to fix it.

Create an uploads folder & copy the sample.pdf file which you want to convert as png. since here I am only going to show you how to convert the pdf to png I am using the pdf as a static path you need to upload that pdf file via REST API.
