# New import from _filter import LocationFilterįrom .rectangle import Rectangleĭ: typing. It gets notified of all Events when rendering the Page and passes those (to its children) that occur inside predefined bounds:įrom _text_extraction import SimpleTextExtraction In order to allow borb to filter out a Rectangle we'll be using the LocationFilter class. Let's refine this code and tell borb which Rectangle we are interested in.įor instance, let's extract the shipping information (but you can modify the code to retrieve any area of interest). This is of course not very useful to us as this would require more processing before we can do much with it, though this is a great start, especially compared to OCR-scanned PDF documents! This code-snippet should print all the text in the invoice, in reading order (top to bottom, left to right): Date With open( "output.pdf", "rb") as pdf_in_handle:Īssert d is not None print(l.get_text_for_page( 0)) L: SimpleTextExtraction = SimpleTextExtraction() # New import from _text_extraction import SimpleTextExtraction We'll start by extracting all the text: import typing RegularExpressionTextExtraction: Matches a regular expression, and returns the matches per page.SimpleImageExtraction: Extracts all images from a PDF.SimpleTextExtraction : Extracts text from a PDF.If you'd like to read more about How to Create Invoices in Python with borb, we've got you covered! In the previous guide, we've generated a PDF invoice, using borb, which we'll now be processing. Installing borbīorb can be downloaded from source on GitHub, or installed via pip: $ pip install borb Creating a PDF Invoice in Python with borb In this guide, we'll take a look at how to process a PDF invoice in Python using borb, by extracting text, since PDF is an extractable format - which makes it prone to automated processing.Īutomating processing is one of the fundamental goals of machines, and if someone doesn't supply a parsable document, such as json alongside a human-oriented invoice - you'll have to parse the PDF contents yourself. It offers both a low-level model (allowing you access to the exact coordinates and layout if you choose to use those) and a high-level model (where you can delegate the precise calculations of margins, positions, etc to a layout manager). In this guide, we'll be using borb - a Python library dedicated to reading, manipulating and generating PDF documents. In fact, PDF is based on a scripting language - PostScript, which was the first device-independent Page Description Language. To achieve this, PDF was constructed to be interacted with via something more like a programming language, and relies on a series of instructions and operations to achieve a result. It was developed to be platform-agnostic, independent of the underlying operating system and rendering engines. The Portable Document Format (PDF) is not a WYSIWYG (What You See is What You Get) format.
