3 .TH LINKICC 1 "September 30, 2004"
4 .SH NAME
5 linkicc - little cms device link generator.
6 .SH SYNOPSIS
7 .B linkicc
8 .RI [ options ] " profiles"
9 .SH DESCRIPTION
10 lcms is a standalone CMM engine, which deals with the color management.
11 It implements a fast transformation between ICC profiles.
12 .B linkicc
13 is a little cms device link generator.
14 .P
15 Links two or more profiles into a single devicelink profile.
16 Colorspaces must be paired except Lab/XYZ, that can be interchanged.
