I made some modifications to a program called "xv"....   One of the mods enables
xv to output an eps file...   The process isn't especially streamlined, but here's
how I do it:
1) use a postscript interpreter to get the postscript image rendered onto the
   screen of my Sun workstation (I use "pageview", an OpenWindows utility)...
2) Capture the rendered postscript from the Sun's screen into a rasterfile
   (I use "snapshot", another OpenWindows utility)...
3) Read in the rasterfile and output the EPS file using "xv"...   I have found
   that I usually have to crop the image, and I also have to edit the colormap...
   The problem is that although the EPS spec will permit a "gray-scale" image,
   most programs that I have seen that use the preview portion of the EPS only
   can handle a bitmap...   So, you have to tell "xv" which colors you want mapped
   to black and which colors you want mapped to white...    Same is true for gray
   scale images...    I guess I could have written code that would have picked
   the color -> black/white mapping automatically, but it probably wouldn't map
   it the way the user really wanted it mapped...
4) the output of xv is an EPS file with a bitmap (i.e. black-and-white) preview
   section, followed by a postscript "image"....    The final step is to discard
   the postscript image, and replace it with the original postscript file...

I'm not partial to having to go through 4 steps to make an EPS file...
If someone has a better way of doing this, I'd like to hear it...

I'd be glad to give out my modified version of "xv"....    I sent the changes to the author
of xv (John Bradley  -  bradley@cis.upenn.edu), but he's working on making xv into
a commercial product so I'm not sure if/when he's gonna publish another release of
xv....
