borb

borb is a library for creating and manipulating PDF files in python.

0. About borb

borb is a pure python library to read, write and manipulate PDF documents. It represents a PDF document as a JSON-like datastructure of nested lists, dictionaries and primitives (numbers, string, booleans, etc)

This is currently a one-man project, so the focus will always be to support those use-cases that are more common in favor of those that are rare.

📣 I am excited to share that a major release is in the works! 🎉 This update includes significant improvements and new features designed to enhance performance, usability, and functionality. While this update is taking longer, I am confident that the added benefits will make the wait worthwhile. Stay tuned for more updates and thank you for your continued support!

📣 update on the major release: The vast majority of things related to creating a PDF are done. Major changes include:

• The codebase no longer uses Decimal.
• The codebase no longer uses external files (some people were experiencing issues with that when trying to pack their code into an executable.)
• Annotation objects have become part of the LayoutElement hierarchy.
• LayoutElement objects are characterised by 2 methods: get_size and paint.
• The codebase is fully checked using mypy.
• The codebase is fully checked using pydocstyle.
• The codebase is tested even more thoroughly (1200+ tests!)

Next up is reading a PDF, after which I can work on modifying a PDF in a way that is fully consistent with the ISO standard.

1. About the Examples

The examples can be found in a separate repository. This ensures the borb repository stays relatively small, whilst still providing a thorough knowledgebase of code-samples, screenshots and explanatory text.

Check out the examples repository here!

They include;

• Reading a PDF and extracting meta-information
• Changing meta-information
• Extracting text from a PDF
• Extracting images from a PDF
• Changing images in a PDF
• Adding annotations (notes, links, etc) to a PDF
• Adding text to a PDF
• Adding tables to a PDF
• Adding lists to a PDF
• Using a PageLayout manager

and much more

1.0 Installing borb

borb can be installed using pip

pip install borb

If you have installed borb before, and you want to ensure pip downloads the latest version (rather than using its internal cache) you can use the following commands:

pip uninstall borb
pip install --no-cache borb

1.1 Hello World

To give you an immediate idea of the way borb works, this is the classic Hello World example, in borb:

from pathlib import Path

from borb.pdf import Document
from borb.pdf import Page
from borb.pdf import SingleColumnLayout
from borb.pdf import Paragraph
from borb.pdf import PDF

# create an empty Document
pdf = Document()

# add an empty Page
page = Page()
pdf.add_page(page)

# use a PageLayout (SingleColumnLayout in this case)
layout = SingleColumnLayout(page)

# add a Paragraph object
layout.add(Paragraph("Hello World!"))
    
# store the PDF
with open(Path("output.pdf"), "wb") as pdf_file_handle:
    PDF.dumps(pdf_file_handle, pdf)

2. License

borb is dual licensed as AGPL/Commercial software.

AGPL is a free / open source software license. This doesn't mean the software is gratis!

Buying a license is mandatory as soon as you develop commercial activities distributing the borb software inside your product or deploying it on a network without disclosing the source code of your own applications under the AGPL license. These activities include:

• Offering paid services to customers as an ASP
• Serving PDFs on the fly in the cloud or in a web application
• Shipping borb with a closed source product
