ICCLINK(1)						      General Commands Manual							ICCLINK(1)

NAME

       icclink - little cms device link generator.

SYNOPSIS

       icclink [options] <profiles>

DESCRIPTION

       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
