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
       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 re-
       move 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  consider-
       ably  reduce  the main PDF-file's size.	(Note: Ghostscript 9.17	- 9.21
       needs -dPDFDontUseFontObjectNum commandline option for removing	dupli-
       cate  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	embed-
       ded, 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.)
