Dear all,
I am often using scribus
http://web2.altmuehlnet.de/fschmid/
Scribus is a Layout program for Linux�, similar to Adobe� PageMaker,
QuarkXPress, Adobe� InDesign,
except that it is published under the GNU GPL.
I have successfully read in your image and I am able to save it in eps.
If you are interested I could mail you the result.
Another problem we have had at the linux is solved by this too.
The eps output is in cmyk and if you like you can do color separations.
regards
Reimar
