Built-in Profiles

*Lab2  -- D50-based v2 CIEL*a*b
*Lab4  -- D50-based v4 CIEL*a*b
*Lab   -- D50-based v4 CIEL*a*b
*sRGB  -- sRGB color space
*Gray22 - Monochrome of Gamma 2.2
*Gray30 - Monochrome of Gamma 3.0
*null   - Monochrome black for all input
*Lin2222- CMYK linearization of gamma 2.2 on each channel


To color correct from scanner to sRGB:
	jpgicc -iscanner.icm in.jpg out.jpg

To convert from monitor1 to monitor2:
	jpgicc -imon1.icm -omon2.icm in.jpg out.jpg

To make a CMYK separation:
	jpgicc -oprinter.icm inrgb.jpg outcmyk.jpg

To recover sRGB from a CMYK separation:
	jpgicc -iprinter.icm incmyk.jpg outrgb.jpg

To convert from CIELab ITU/Fax JPEG to sRGB
	jpgicc -iitufax.icm in.jpg out.jpg

To convert from CIELab ITU/Fax JPEG to sRGB
