pax – Extract and reinsert PDF annotations with pdfTeX

If PDF files are in­cluded us­ing pdfTeX, PDF an­no­ta­tions are stripped. The pax project of­fers a so­lu­tion with­out al­ter­ing pdfTeX. A Java pro­gram (pax.jar) parses the PDF file that will later be in­cluded. The pro­gram then writes the data of the an­no­ta­tions into a file that can be read by TeX.
The LaTeX pack­age pax ex­tends the graph­ics pack­age to sup­port the scheme: if a PDF file is in­cluded, the pack­age looks for the file with the an­no­ta­tion data, reads them and puts the an­no­ta­tions in the right place.
