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 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.

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.)
