Re: Saving Image data in eps format.

[Jonathan Stickel]

You might try the using "epstk"

http://www.epstk.de/

It is an alternative plotting toolkit for Octave that produces 
exclusively eps output.  It includes a function for writing images.  The 
syntax can be something like

 M=rand(50);
 eopen ("epstktest.eps")
 eimagesc (M)
 eclose

This will produce an eps file with the scaled image representation of 
matrix M.
