From the jpeg2ps site,
jpeg2ps is a utility for converting JPEG images to compressed PostScript Level 2 or 3 files (without uncompressing the images). The JPEG data is simply »wrapped« with PostScript which yields considerably smaller PS files. jpeg2ps is a simple command line utility and can be used on DOS, Windows, and Unix machines.
I have created an RPM that can be installed using via the kriehn repository using yum:
~> sudo yum install pngoutIf Hit Enter and press 'y' when asked if you wish to install the package, along with any dependencies. After it is installed, source your ~/.bashrc file:
~> source ~/.bashrcIf you need help with the syntax, type:
~> pngout --helpYou are now ready to use jpeg2ps. If you need help with the syntax, read the man page.
