Hi all,
if I produce scores that are to be printed on double-sided, folded
sheets (i.e. four A4 pages on one A3 sheet) I need to find a way to
add empty pages to the end of the score.
pdfjam is part of the pdfpages package. Try something like
pdfjam --landscape --keepinfo --paper a3paper --nup '2x1'
--outfile out.pdf -- in.pdf
I have to repeat myself: My issue is not about the imposing from A4
to A3.
I want to produce a file in A4 that *can* be imposed on a folded A4
paper.
So it has to have a page count of a multiple of 4.
Well, then try something like this:
#!/bin/bash
if [ -z "$2" ]; then
echo usage: $0 in.pdf out.pdf
exit 1
fi
#
# we need pdfjam, so abort if it is not installed
#
PDFJAM=`which pdfjam`
if [ "$PDFJAM" = "" ]; then
echo cannot find pdfjam!
exit 2
fi
#
# we need pdfinfo, so abort if it is not installed
#
PDFINFO=`which pdfinfo`
if [ "$PDFINFO" = "" ]; then
echo cannot find pdfinfo!
exit 3
fi
#
# read the number of pages and calculate the remainder of
# (number of pages) / 4
#
INPAGES=`pdfinfo $1 | grep Pages | grep -o "[[:digit:]]*"`
let "MOD = INPAGES % 4"
#
# add 0 to 3 empty pages
#
if [ $MOD -eq "3" ]; then
pdfjam --keepinfo --paper a4paper --outfile $2 -- $1 '1-,{}'
elif [ $MOD -eq "2" ]; then
pdfjam --keepinfo --paper a4paper --outfile $2 -- $1 '1-,{},{}'
elif [ $MOD -eq "1" ]; then
pdfjam --keepinfo --paper a4paper --outfile $2 -- $1
'1-,{},{},{}'
else
cp $1 $2
fi
exit 0
