I have had very good success with ImageMagick which can convert nearly
any image format into nearly any other image format.  It has a GPL-like
lisence and is available for nearly any platform at


The source code and binaries are available here or at your favorite Linux
download sites.  

>From the command line, converting from postscript to jpg is as easy as
# convert plot.ps plot.jpg

Resolution can be improved by arguements like
# convert -density 288 -geometry 25% plot.ps plot.gif

which essentially says to put more information into a smaller region.

Additionally, there are all kinds of wrappers for the ImageMagick
libraries, including Perl, Python, and C/C++.
