EXTRACTPDFMARK(1)	     General Commands Manual	       EXTRACTPDFMARK(1)

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

SYNOPSIS
     extractpdfmark file.pdf > file.ps

DESCRIPTION
     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 in-
     cludes 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  -dPDFDontUse-
     FontObjectNum  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-des-
     tinations,  etc.	As a result, when you open the final PDF, it is not dis-
     played 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.

EXAMPLE
     $ extractpdfmark TeX-System-Outputted.pdf > Extracted-PDFmark.ps
     $ gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite \
	  -dPDFDontUseFontObjectNum -dPrinted=false \
	  -sOutputFile=Final.pdf \
	  TeX-System-Outputted.pdf Extracted-PDFmark.ps

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