I printed the PNG and PS file. The result looks same on paper as well. I was
comparing the two ps file one from IDL one from MPL. IDL looks neat both on
the screen and printed.

OK, here is one more comparison.

I use xpdf distiller, and set the pdf comparison to 0 in the rc file.

http://ccnworks.googlecode.com/svn/trunk/test.png
http://ccnworks.googlecode.com/svn/trunk/test.ps
http://ccnworks.googlecode.com/svn/trunk/test.eps
http://ccnworks.googlecode.com/svn/trunk/test.pdf

PS and EPS outputs are almost alike to my eye. Setting ps.distiller.res to
6000 DPI doesn't make a difference either. PDF backend produces the highest
quality output. However the problem with that I can't include pdf images on
a regular OpenOffice document :(

With xpdf the line is plotted blue correctly as it is seen on my screen.
Before it was drawing a red-line.
