Hi,
I am trying to make a makefile to convert PDFs in a directory to 4-up
PDFs using psnup but I am not able to.
I have L??N.pdf files in a directory and wish to produce a corresponding
4-up PDF for each file named L??N-4up.pdf.
I have a shell script which converts all L??N.pdf files to 4up PDF files:
#########################################################
#!/bin/bash
if (( $# != 1 )); then
echo "Usage: $0 <pdf file>"
exit -1
fi
#get the base name of the file
bn=`basename $1 .pdf`
#use acroread to get the PS of the file. acroread gives smaller PS
#files than pdf2ps!
acroread -toPostScript $1
#now convert the PS file to 4up and then to the final PDF version
psnup -m0.5cm -l -Pletter -pletter -4 ${bn}.ps | ps2pdf - ${bn}-4up.pdf
#delete the intermediate ps file
rm -f ${bn}.ps
###############################################################
This works great, but using a makefile would be even better, won't need
to run the script on all PDF in a directory if only a few are revised.
Here is my dismal attempt at making a makefile:
#########################################################
SRC=$(wildcard L??N.pdf)
OBJS=$(patsubst %N.pdf,%N-4up.pdf,$(wildcard L??N.pdf))
#reset recognized suffixes
.SUFFIXES: N.pdf N-4up.pdf
#%N-4up.pdf: %N.pdf
# echo 'making #> #@'
%N-4up.pdf: %N.pdf
echo "making $@ from $?"
4ups: *N-4up.pdf
#########################################################
Any help in making this makefile is greatly apprecaited.
Thanks,
->HS
