The PGPLOT package can produce high quality postscript output. The output files are, however, not compressed and so can be quite large and in particular pose problems when making submission to on-line article archives such as ArXiv
The output files can usually be drastically compressed by making use of the facilities already build in to the newer versions postscript language. I’ve found that the following sequence of post-processing operations produces identical output and often much smaller files:
Normalisation of the original postscript figure using the “eps2eps” utility:
eps2eps infile.eps interfile1
Compression using the encode.ps utility script (as a text file). This script converts the postscript to internally compressed postscript representation. Invoke as:
gs -q -dLEVEL3 -dASCII -- encode.ps interfile1 interfile2
Recreation of the bounding box using the “ps2eps” utility:
cat interfile2 | ps2eps -f -O -B -E > finalfile.eps
Above infile.eps
is the postcript figure as produced by PGPLOT,
interfile1
and interfile2
are intermediate files and
finalfile.eps
is the final compressed encapsulated
postscript figure.
Command Summary:
eps2eps infile.eps interfile1
gs -q -dLEVEL3 -dASCII -- encode.ps interfile1 interfile2
cat interfile2 | ps2eps -f -O -B -E > finalfile.eps
