Is there an easy to use Python library to read a PDF file and extract its text?
the answer is pdfminer as others have said but if the libraries aren working for you it likely because you are expecting too much from them. You need to understand how the pdf file format works as opposed to how format works. Specifically we all expect to be able to use a library to parse some file format for and be able to iterate through the line by line but what if the has no line characters? How would the library know what constitutes a line? Most libraries won try to guess at that and honestly we wouldn want them to because if the line isn represented by a line character then the concept of line isn really part of the (is it?) and we are using the library to extract **. In pdf is laid out meaning that a particular object get displayed at a particular xy position on the page. So what you might think of as 3 lines would actually be 3 objects displayed at (xy) (x y-2) (x y-4) so a extraction library would just pull out the but you have no line data. (IRRC pdfminer hands you String as output just a big String not a (line) iterable it was because PDFMiner didn work for me that I had to study up and learn a bit about pdf to get what I wanted out of the files). The upside is this You finally get a chance to roll your own. Fortunately extracting the out of a pdf is very well defined and simple goal. And fortuanately PDF is a very well documented and very well understood file format so google is going to be very helpful. If pushes to shove the rendering part of the spec is less than 2 pages but you won need to go there. Start here Introduction to PDF s Then read the wikipedia article which is super well written. Then you will have to open the file in editor and study it which won be hard if you are interested only in . Use this as a tool to understand the stream writing operators Adobe Portable Document Format The accepted answer to the following SO tells you what you need to investigate to understand how is encoded within the pdf Programatically rip from a PDF File (by hand) - Missing some Google anything you wish to understand and you will be brought to cool sites like planetpdf where they have great articles. It should take you a day or two to hand write your parser and you will learn a lot in the process about something prettymon. The libraries have to be general so they are going to be limited. (perhaps irrelevant the pdfs I was working with are linearizedsee the ed referenceswhich made studying the in the pdf and mapping to the layout on the screen super simple I didn study an non-linearized files because i didn have to but if it makes things harder there a ton of code out there to linearize a pdf but not a lot out there that can go the otherway)
Is there a tool (say Python library or so) for image processing techniques to scrape PDF documents for information such as shapes, objects and text?
I think there's a couple of options albeit I'm not really sure what you're looking fornIf you want the from the PDF check out the PyPDF2 library s . It could alse be worth looking into getting the shape information in this way. If that PyPDF2 for some reason doesn't cut it you could try running an OCR program on the document (Optical Character Recognition) like Tesseract s . You might need to convert your document to TIFF or PNG which can be done with Ghostscript 3 some Python packages calims to be able to do it but AFAIK they all rely on Ghostscript so just go with Ghostscript and the subprocess sh or envoy modules 's also some Python packages s avaiable for interacting with Tesseract but I doesn't have any experience using them so I would probably just go formunicating with Tesseract through the subprocess sh or evnoy modules. Hope it helps )
What is a good PDF rendering library for Django/Python?
Django Tools Django easy PDF s is the best library for creating PDF documents. It is actually an app which you need to install in your django project. It can render documents form HTML and CSS. Using s object coordinates metadata from PDF files is easy to do with pdf miner. It supports python 2.4+ but python 3 is not yet supported (Duh!!) Code2pdf s is another interesting library that converts your source code into pdf file with syntax highlighting line numbers etc. WeasyPrint is quite good although it can't be installed in a virtualenv as it depends on a good deal of GNOME code (GDK cairo gobject etc) Another drawback is that jpegs don't appear to render properly and everything must be converted to PNG before being included in a PDF generated with Weasyprint. But it is being actively maintained and issues can be resolved. PyPDF2 s Active development. Split merge crop creating watermarks etc. of PDF files. Pure Python. Includes sample code andmand line interface good documentation. Python 2 and 3 support. The above list is pretty much what I have used up till now for various projects. There are other tools which your can check out on this page s for your particular requirements. Most of these libraries have overlapping capabilities. I prefer to use django easy pdf for my websites. Pdfminer for extraction and Pypdf2 for manipulating pdf files.

How do I convert scanned documents to editable word documents?
Well converting scanned documents to editable word documents is not that easy. Furthermore it depends whether your document is PDF or s. For the PDF's I nevere to try OCR's as I had integrated it with my Python code where I was using PyPDF2 u232 which is a python library built as a PDF toolkit. It is capable of Extracting document information (title author ...) Merging documents page by page Merging multiple pages into a single page Also there are more ways to parse PDF's using Python. So keep exploring! With the s) Google Cloud's VisionAPI (it offers powerful pre-trained machine learning models through REST and RPC APIs assigns labels to catalogue) and tesseract (Tesseract is an OCR engine for various operating systems. It is free software released under the Apache License Version 2. and development has been sponsored by Google since 26). Mathpix OCR was okay it has Python integration. For slight details it works fine. Google Cloud's Vision API worked best but since I did not find a better way to integrate it with Python and also it was billable so I left it. For Tesseract in the windows I had to install Tesseract then I integrated it with my Python code using the pytesseract library of Python and it worked great. At least it did not ask for billing unlike Google Cloud's Vision API. So now you have the s of s to editable word documents where you just have to upload your scanned documents on their sites and they will convert them to word documents and then you can download them. However they are not 1% accurate. Also there are privacy issues when using the online OCR's. If you find it useful like it. Also please help me inments if youe across better OCR's or ways to convert scanned documents to editable word documents and if you get a way to use Google Cloud's VisionAPI without enabling billable.
