Everything is already there. The LCMS library can work on either an
array of bytes of RGB values or on three values from a table (for
indexed images), it will write it's output into a new array (or
return just the values for the color index). All I have to do
is open two profiles, connect them to a transformation. This
transformation then gets a pointer to the input data, a=20
pointer to the output data and that's it.=20

=2E.. and of course you need a way to specify the path to the
profiles.=20


Other than that a fast CPU would help :-) Actually it's not that
bad: The LCMS library is optimized for speed.=20
