gimp and CMS
 
I'm using Gimp on Ubuntu

I have the color management turned on and have it configured to convert
to the Adobe 98RGB working space if a profile is embedded in the image
file, I have chosen an approximation for my monitor profile
(edit/preferences/color management)

but (file/new/advanced) does not include an option for a profile, just
RGB or grey scale

I will search for some images either in Adobe 98RGB or with some
embedded profiles, and standard datas (I see some B%W film data out
there http://registry.gimp.org/node/27897 )

shouldn't gimp allow for the file/new cube to be mapped to a working
space gamut, RGB or otherwise? I realize my choice of monitor
approximation may override any end goal, but I am just hacking with Yuv,
generic/convolution and grey scale in curves to get at UCR/GCR/UCA and
whatever else may come of it

looks like any moves in uvL, h*s*L*, etc. that I wanted to code in gimp
can be handled under the Colors/Map routines, Alien Map is very good in
HSL model with available frequency and phase shifts on selectable HSL
channels

I don't have a color or spectrum measurement device for my monitor or
printer and I don't know the price/quality ranges, I don't even have my
printer attached

I might still hack at the color stuff and fourier and laplace stuff I am
interested in for something to do, and likely to spend more time
learning gimp and what plug-ins are already registered

anyone know how to populate a palette to use with the Color/Map/Palette
map filter? might be easier to map palettes with filters than just
making filters
