Also as a side note I see that there is a pdftoraster.c file that is part of GS<br>
9. Is this a CM enabled replacement for the pdftoraster CUPS filter? Or is<br>
this something else? Has anyone had a chance to look at GS 9 yet to see if it<br>
has what is needed to be a basis for a CM enabled CUPS PDF based work flow?</blockquote><div><br></div><div>I can't comment on the CUPS side, but I've had long talks with Michael from Artifex who did their CM implementation and it is an excellent implementation with support for not only the standard itself but also enough flexibility for their OEMs to implement various extensions (such as n-colourant profiles and PDF/X-5n).</div>
