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.

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.
