OpenPDF is a free and open-source Java library for creating and manipulating PDF files. It is licensed under the LGPL and MPL.

The openpdf module is the main core module of the library. It contains the essential classes for PDF creation, reading, and modification, including:

• PdfReader – for reading existing PDF documents
• PdfWriter – for generating new PDF files
• Document, Paragraph, Chunk, Font – for building structured content
• Low-level APIs for working directly with the PDF specification

This module is required by most other modules in the project, such as:
