2.2.0

OpenPDF 2.2.0 Released!

We’re excited to announce the release of OpenPDF 2.2.0, a new milestone in our ongoing mission to build a modern, fully open-source PDF library for Java.

What's New

openpdf-renderer Module Added (#1357)

We’ve added a brand new module: openpdf-renderer.

This module integrates the openpdf-renderer engine into OpenPDF, enabling:

• High-quality PDF rendering to images
• Fast page previews and thumbnails
• Support for converting PDF pages to BufferedImage for use in Java applications

It’s perfect for developers who need visual previews of PDFs in desktop or server-side applications.
