       extractpdfmark - Extract page mode and named destinations as PDFmark from PDF


       extractpdfmark file.pdf >


       This manual page documents briefly the extractpdfmark command.

       When you create a PDF document using a TeX system, you may include many small PDF files in
       the main PDF file.  It is common for each of those files to use the same fonts.

       If the small PDF files contain embedded font subsets, the TeX system includes  them  as-is
       in  the  main PDF.  As a result, several subsets of the same font are embedded in the main
       PDF.  It is not possible to remove the duplicates since the subsets differ.   This  vastly
       increases the size of the main PDF file.

       On  the other hand, if the small PDF files contain embedded full font sets, the TeX system
       also includes all of them in the main PDF.  This time, the main PDF contains duplicates of
       the  same full sets of fonts.  Therefore, Ghostscript can remove the duplicates.  This may
       considerably reduce the main PDF-file's  size.   (Note:  Ghostscript  9.17  -  9.21  needs
       -dPDFDontUseFontObjectNum  commandline  option  for  removing duplicate fonts.  If you use
       Ghostscript 9.22+, you cannot use this "full set embedding" method since it cannot  remove
       duplicate fonts.  In this case, you can use "*not* embedding" method as following.)

       Finally,  if  the small PDF files contain some fonts that are not embedded, the TeX system
       outputs the main PDF file with some fonts missing.  In this case,  Ghostscript  can  embed
       the necessary fonts.  It can also significantly reduce the required disk size.

       Either way, when Ghostscript reads the main PDF produced by the TeX system and outputs the
       final PDF it does not preserve PDF page-mode and named-destinations, etc.   As  a  result,
       when  you  open the final PDF, it is not displayed correctly.  Also, remote PDF links will
       not work.

       This program is able to extract the page mode and named destinations as PDFmark from  PDF.
       By using this you can get the small PDF files that have preserved them.

       (Note: Ghostscript 9.26+ needs -dPrinted=false commandline option.)
