Hallo David,<br>
<br>
I have tried all combinations of color models for my printer object and images
(indexed, rgb ),<br>
under unix and linux OS but the output is still gray.<br>
<br>
My question is: can the XPrinter option 'Generic(File Only') and EPSF selected
print colored <br>
graphic trees. If not, is there any posibility to save a graphics tree/view
to an eps file? <br>
<br>
Thanks! <br>
<br>
Milan<br>
