Hi :)

why -ir, not -ia?
Just a mistake on my part when changing from 0.7b8 syntax ( -ij) to 1.0.0 syntax (-i<intent> -pj).
I shall change this for the next version, unless people would prefer it to be runtime-selectable? 


2. collink -G Shot.gam -ip -op -ip -cmt -dpp AdobeRGB1998.icc HPED2880.icc 
Shot_lnk.icc
why two -ip?


Another oversight on my part ;)


As I understood from the CMS documentation, in gamut maping mode the -o key 
isn't used at all, as it for simple mode exclusively IMHO. Am I right? There is 
clear division between simple and gamut mapping modes in colllink.htm.
Scar tissue left over from early experiments - you're correct, it should be removed :) 


So the questions: which intent I need to chose in tiffgmut?


I'd say use a unless you have a specific reason not to.


And is there the -o key needed in collink gamut mapping mode?
No, and the next version of ImgTarget will clean up these issues - thanks for pointing them out :) 

All the best,
