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.
