I have a number of pdf file and I'd like to concat them into one pdf.
I'm using Python 3

QUESTION
I've been working on a project in which I extract table data from a pdf with neural network, I successfuly detect tables and get their coordinate (x,y,width,height) , I've been trying to crop the pdf with pypdf2 to isolate the table but for some reason cropping never matches the desired outcome. After running inference i get these coordinates
[[5.0948269e+01, 1.5970685e+02, 1.1579385e+03, 2.7092386e+02 9.9353129e-01]]
the 5th number is my neural network precision , we can safely ignore it
trying them in pyplot works , so there's no problem with them:
However using the same coords in pypdf2 is always off

QUESTION
I have 2 PDF's resultant from splitting a 2-up document composed by 32 pages signatures. Meaning one PDF has pages 1-16, 33-48, 65-80.... and the other has pages 17-32, 49-64, 81-96....
How can I merge both, iterating through 16-page segments of each, using Python? To get a final composed PDF with 1-16, 17-32, 33-48, 49-64.....
I can iterate them page by page and I can combine one full PDF after the other, etc. But can't seem to get the correct way merging by segments.
The first operations are done with external software (Xerox Freeflow Core) and I get to a point where I have 4 files with the 16-page sequences divided in even/odd pages, I join them iterating with:

QUESTION
I have a single PDF that I would like to create different PDFs for each of its pages. How would I be able to so without downloading anything locally? I know that Document AI has a file splitting module (which would actually identify different files.. that would be most ideal) but that is not available publicly.
I am using PyPDF2 to do this curretly
...ANSWER
Answered 2021-May-14 at 13:42To split a PDF file in several small file (page), you need to download the data for that. You can materialize the data in a file (in the writable directory /tmp) or simply keep them in memory in a python variable.
In both cases:
- The data will reside in memory
- You need to get the data to perform the PDF split.
If you absolutely want to read the data in streaming (I don't know if it's possible with PDF format!!), you can use the streaming feature of GCS. But, because there isn't CRC on the downloaded data, I won't recommend you this solution, except if you are ready to handle corrupted data, retries and all related stuff.
QUESTION
I am currently doing a project to extract the contents of a PDF. The code runs smoothly and I am able to extract the text but the extracted text are not in the right order. The code extracts the text in a weird way. The order of the text is all over the place. It does not go from top to bottom and is really confusing.
I looked up online but there was very little help on how to order the text extraction. Most tutorials came up with the same result. For reference, this is the PDF that I am currently testing it on (page 5): https://www.pidm.gov.my/PIDM/files/13/134b5c79-5319-4199-ac68-99f62aca6047.pdf
...ANSWER
Answered 2021-May-16 at 13:44I had to deal with a problem that was similar and it turned out that the module pdfplumber worked better than PyPDF. I guess it depends on the document itself, you should try.
Otherwise another answer to your problem would be to treat the PDFs as images with the pdf2image module and extract the text within them using pytesseract. However it might not be perfect method as the pdf2image method convert_from_path can take quite a long time to run.
I drop some code down here if you are interested.
First of all make sure you install all necessary depedencies as well as Tesseract and ImageMagik. You can find any information regarding install on the website. If you are working with windows there's a good Medium article here.
To convert PDFs to images using pdf2image:
Don't forget to add your poppler path if you are working on windows. It should look like something like that r'C:\\poppler-21.02.0\Library\bin'
QUESTION
I'm writing a code in Python 3 that takes in an XML file and from the links extracts the texts (currently trying with PyPDF2). I have written this function that tries to do it:
...ANSWER
Answered 2021-May-16 at 08:28You can know how many pages there are via getNumPages().
Based on this method, there are two properties: numPages and pages. The first is an alias of getNumPages, so it returns an int (how many pages do you have), while the latter is a list holding all pages objects.

Install PyPDF2
You can use PyPDF2 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
