RGB to CMYK

Hi,

I've started writing a GUI wrapper for nconvert to convert RGB jpegs to CMYK jpegs. Is it possible to convert from rgb to cmyk?

I notice there is a -cspace cmyk, and thought that this would do the trick, but no joy so far

Also, is it possible to embed an .icc profile in the output jpeg?

Has anybody got any pre-written nconvert command lines for me to look at, and learn from

Many thanks,

Brian

Currently icc profile is not supported, -cspace is for RAW files

Pierre,

Thanks for the quick reply - I'll look for something else, then!

I have been experimenting with ImageMagick, which does let you embed profiles, but I couldn't fine-tune enough to get the output I required

Oh, well, I feel a Google coming on!
