[Tuglist] print the color images to monochrome images

[Baskaran]

Dear sir,

This idea is the best for processing figures and i am trying to make it for
the same idea suggested by you. I also see the CTAN.

Thanks for all

Regards

Well, the PStricks package does all its work mainly in PostScript and
should, according to your definition, not be available for TeX.

Basically, you should be able to write something like
\special{ps::some_pscode}
and get that working.  With images, something connected with the
setcolortransfer command might do the trick.  I can't look this up
right now, not having the PostScript Language Reference Manual
(PLRM.pdf somewhere on the net) available here.

Since the mechanisms involved are readily available in PostScript,
somebody might already have made a LaTeX style for it, after all. 
Check CTAN and the Catalogue, perhaps you are lucky.
