Ethan has explained why the ps file does not depend on "set size".

Decrease size of pm3d map in ps file can be done by:

1. Postprocessing your ps file -- see scripts pm3dCompress.awk and
pm3dConvertToImage.awk in gnuplot sources or in
http://gnuplot.sourceforge.net/scripts/

2. Use "with pixels style" patch by Daniel at the "Patches" section on
sourceforge.
