Impressive is a tool to display PDF files that provides visual effects such as smooth alpha-blended slide transitions. It provides additional tools such as zooming, highlighting an area of the screen, and a tool to navigate the PDF pages.

PDFmarks is a technique that accompanies PDF, and that is used to store metadata such as author or title, but also structural information such as bookmarks or hyperlinks.

When Ghostscript reads the main PDF generated by the TeX system with embedded PDF files and outputs the final PDF, the PDF page mode and name targets etc. are not preserved. Therefore, when you open the final PDF, it is not displayed correctly. Also, remote PDF links do not work correctly.

This program is able to extract the page mode and named targets as PDFmark from PDF. In this way, you can obtain embedded PDF files that have kept this information.

Xournal is an application for notetaking, sketching, keeping a journal using a stylus.

flyer-composer can be used to prepare one- or two-sided flyers for printing on one sheet of paper.

Imagine you have designed a flyer in A6 format and want to print it using your A4 printer. Of course, you want to print four flyers on each sheet. This is where Flyer Composer steps in, creating a PDF which holds your flyer four times. If you have a second page, Flyer Composer can arrange it the same way - even if the second page is in a separate PDF file.

This package contains both the command line tool and the gui too.

pdfposter can be used to create a large poster by building it from multiple pages and/or printing it on large media. It expects as input a PDF file, normally printing on a single page. The output is again a PDF file, maybe containing multiple pages together building the poster. The input page will be scaled to obtain the desired size.

This is much like poster does for Postscript files, but working with PDF. Since sometimes poster does not like your files converted from PDF. Indeed pdfposter was inspired by poster.
