Pdfbox

A BaseX interface for the Apache Pdfbox library version 3.

The Apache PDFBox® library is an open source Java tool for working with PDF documents. This project allows creation of new PDF documents, manipulation of existing documents and the ability to extract content from documents.

This interface is packaged in the Expath format. A test suite is available and workflow actions run this on BaseX 10.7 and 11.7.

Note

Currently (v0.1.5) works with BaseX 9.7, but this may change with future versions.

• read PDF page count.
• read any PDF outline and return as map(s) or XML.
• read pagelabels.

• save pdf page range to a new pdf.
