Then, what you will need is a regular expression, that finds any 'RG' or
'rg' color commands, to replace them with 'K' or 'k', respectively.
Of course, the expression needs to be smart enough only to replace
occurrences of 'RG' or 'rg' that is actually color commands.
Searching for occurrences of three space separated numbers followed by space
and then 'RG' or 'rg' is a hack, that might (but only might) be good enough.
Ok, i understood that. But i think the color values must be changed too
or i'm wrong. I think there must be a conversion from rgb to cmyk values?!?
Then, the XRef Table needs to be rebuilt.
This tasks should be possible to do with another regular expression,
That searches for any occurrences of '[anInteger] [anotherInteger] obj' and
adds the byte offset positions of these matches into a new XRef Table, that
in the end should replace the existing XRef Table.
Sorry don't understand that. For what is this task?
Timo
Also, the number on the second last line of the document should be replaced
with the number of bytes written until the occurrence of the last 'endobj'
command.
There is a number of plug-ins, that can be used from within Adobe Reader to
convert the RGB colors of a PDF document into CMYK colors.
There is a tool named QuiteABoxOfTricks that can be found at
http://www.quite.com doing this.
I am sure it is possible to setup a batch processing solution as well, in
order to create a totally automated hack solution for this lack.
PitStop server is another solution.

Ben,
The President of my employer is a lawyer. Dunno if open-source will
happen anytime soon for that lib. ;-)
Have you checked if the open-source Multivalent lib supports this type
of operation? I'll try and take a gander too, but you should check
and see.
I will check it next week.
Thanks for the tip.
I think it should be possible to create cmyk pdf from FOP directly. So
if you can't "open-source" your solution, maybe you can talk a little
bit about how to do such a replacement, so that i can maybe hack
something similar into FOP?
Timo
