Hi Robert,

Which we've very much appreciated, even though I still have to try out
your latest.  I've been busy with other things, like making dcraw do
the right (IMHO) thing.  But I digress.

Don't worry, I wasn't feeling unappreciated - just torn between two projects, like yourself :)

It would *really* be helpful to plug this into the Print plugin, if
not Gimp-Print itself, so that when the GIMP feeds 8 bit values to the
plugin these values are reprocessed into 16 bit values, rather than 8
bit ones.

This should be a fairly trivial change once we have the infrastructure to get the current working profile and/or the image's profile into plugins in general.

The print plugin would itself need to link against lcms, and it would simply fetch the current working profile (or the image's own profile if there is one), and create a transform from 8-bit data in the source profile to 16-bit data in the destination profile.

The sticking point would be the destination profile - the user would need one that accurately describes gimp-print's characteristics! We could of course just use sRGB (which lcms has built-in) as a default.

All the best,
