OpenPDF is open source software with a LGPL and MPL license. It is a fork of iText version 4, more specifically iText svn tag 4.2.0, which was hosted publicly on sourceforge with LGPL and MPL license headers in the source code, and LGPL and MPL license documents in the svn repository. Beginning with version 5.0 of iText, the developers have moved to the AGPL to improve their ability to sell commercial licenses.

We have now different versions of OpenPDF, and they require different versions of Java:
- The 2.0.x Branch requires Java 17 or later.
- The 1.4.x Branch requires Java 11 or later.
- The 1.3.x Branch requires Java 8 or later.
- Some versions of 1.3 where release with Java 11 as minimum requirement, but we have reverted this to Java 8 as minimum requirement.
- OpenPDF versions 2.0.x: We are working on modernizing the OpenPDF library for Java 17+.
As of 1.3.21 the UTF-8 Liberation fonts moved to its own module, to reduce the size of the OpenPDF
jar. If you want to use the bundled UTF-8 fonts, please add the following dependency to your project
and use the class org.librepdf.openpdf.fonts.Liberation.
<dependency>
<groupId>com.github.librepdf</groupId>
<artifactId>openpdf-fonts-extra</artifactId>
<version>${openpdf.version}</version>
</dependency>OpenPDF supports glyph substitution which is required for correct rendering of fonts ligature substitution requirements. FOP dependency is required to enable this feature. Refer following wiki for details: wiki
OpenPDF supports OpenType layout, glyph positioning, reordering and substitution which is e.g. required for correct positioning of accents, the rendering of non-Latin and right-to-left scripts. OpenPDF supports DIN 91379. See: wiki
