pikepdf | Python library for reading and writing PDF | Document Editor library

Okay i did try Something which ist not nice but did work for me I will sketch the concept and show code afterwards:

1. split String on '=' a) using (import re) and: re.split('=', Gleichung)

2. List Element[0] is part before '=' List Element[1] is part after '='

3. use Sympy to render latex code for each Element

4. join new strings ( latex code strings) by '='

5. give this new string into shown function

The whole file has to be downloaded to a device via RAM so the blob as a FILE can be parsed at the very END for one OR more %%EOF and the location of page 0 (it gets converted to 1 or i) it could be ANYWHERE IN THE STREAM,.

THEN you can navigate to other sequential numbered pages in the RANDOM order they are built. Any complaints please contact Adobe.

However it is easiest if it is cached as a physical FILE object. If you dont want that on disk use a ram drive for your browser.

Again those two objects at bottom of page one could be anywhere mixed into the content of "page" 99's objects, or otherwise. each letter in a PDF can in its extreme be more than one object anywhere in the file. but a good authoring editor would try to keep them as lines by lines. (there is no such PDF thing as a word or paragraph.)

We can Print the file as Plain Text to see how it is composited and although (secured) that is allowed.

I tried printing from browser with little success but know that can depend on browser system and OS print drivers. Here I have printed the page as text using Acrobat portable, so we can see the sequential offsets of each text block from Left Hand margin JUST LIKE a PDF VIEWER would need to rebuild them.

UPDATE You said your target is (1380-4.4) to the RIGHT of ALTERNATE but again A PDF has no concept of Left and Right or BEFORE or AFTER so we find IN THIS FILE the variable target is in 2 separate pieces PRIOR to the KNOWN characters which luckily is a complete single block (alternate). Thus here proximity of plain text could well work if the capture is confined to that nearby locality. However there is no guarantee that ALTERNATE would always be a single block.

It was perhaps not a good Idea To show the way a Printer would be given a stream of sequential data Here is the way one PDF viewer goes about decrypting the file

As stated on this occasion the word ALTERNATE is defined as text however the next item is the "3" under "B" which is text as a vector path it is not called a "character" although it looks like one but a numbered glyph from a font table. We do see later that some of those numbers are stored as "text" and for your target it is mixed in with similar text in the same object.

Thus you need to call a PDF interpreter to give you a meaningful translation of all bits and pieces of objects so that you can extract the "right" text.

The easiest way for a "simple" one line target in a complex file is to use MuPDF to first tidy up the file

See the below code to get the desired output with auto-generated password for each pdf:

Edited Implemented in your code:

You can restart your kernel of your notebook and install pikepdf

!pip install pikepdf

Then you should import it by

from pikepdf import pdf

and so on.

You should install your dependencies first then run the code.

Try using file instead of filename:

strdup is an extension to standard C.
