borb

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

Description

Working with PDF can be complex and challenging at the best of times. This is why borb was created with user-friendliness in mind. Users are not required to have extensive PDF knowledge.

Many competing libraries require the user to have detailed knowledge of the inner workings of the PDF format. Even something as trivial as adding text to a page would require you to know the coordinate system in PDF.

borb offers automatic page layout that takes care of margins, padding, leading, and more.

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.

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
