Usage

Overview

lcms is a standalone CMM engine, which deals with the color management. It implements a fast transformation between ICC profiles. icclink is little cms device link generator.

Links two or more profiles into a single devicelink profile. Colorspaces must be paired except Lab/XYZ, that can be interchanged.

Options

-8

Creates 8-bit devicelink.

-b

Black point compensation.

-c <0,1,2,3>

Precission (0=LowRes, 1=Normal, 2=Hi-res). [defaults to 1]

-d description

Description text (quotes can be used).

-h <0,1,2,3>

Show summary of options and examples.

-i profile

Input profile (defaults to sRGB).

-k <0..400>

Ink-limiting in % (CMYK only)

-o profile

Output devicelink profile. [defaults to 'devicelink.icm']

-t <0,1,2,3>

Intent (0=Perceptual, 1=Colorimetric, 2=Saturation, 3=Absolute).

-x

Creatively, guess deviceclass of resulting profile.

Built-in profiles:

	*Lab  -- D50-based CIEL*a*b (PCS)
	*XYZ  -- CIE XYZ (PCS)
	*sRGB -- sRGB color space
	*Gray22- Monochrome of Gamma 2.2
	*Lin2222- CMYK linearization of gamma 2.2 on each channel

Examples

To create 'devicelink.icm' from a.icc to b.icc:
	icclink a.icc b.icc
To create 'out.icc' from sRGB to cmyk.icc:
	icclink -o out.icc *sRGB cmyk.icc
To create a sRGB input profile working in Lab:
	icclink -x -o sRGBLab.icc *sRGB *Lab
To create a XYZ -> sRGB output profile:
	icclink -x -o sRGBLab.icc *XYZ *sRGB
To create a abstract profile doing softproof for cmyk.icc:
	icclink -t1 -x -o softproof.icc *Lab cmyk.icc cmyk.icc *Lab
To create a 'grayer' sRGB input profile:
	icclink -x -o grayer.icc *sRGB gray.icc gray.icc *Lab
To embed ink limiting into a cmyk output profile:
	icclink -x -o cmyklimited.icc -k 250 cmyk.icc *Lab
