public final class ICC_ProfileGray extends ICC_Profile
The ICC_ProfileGray class is a subclass of the ICC_Profile class that represents profiles which meet the following criteria: the color space type of the profile is TYPE_GRAY and the profile includes the grayTRCTag and mediaWhitePointTag tags. The getInstance methods in the ICC_Profile class will return an ICC_ProfileGray object when the above conditions are met. Examples of this kind of profile are monochrome input profiles, monochrome display profiles, and monochrome output profiles.

The advantage of this class is that it provides a lookup table that Java or native methods can use directly to optimize color conversion in some cases.

To transform from a GRAY device profile color space to the CIEXYZ Profile Connection Space, the device gray component is transformed by a lookup through the tone reproduction curve (TRC). The result is treated as the achromatic component of the PCS.


                 PCSY = grayTRC[deviceGray]

 
The inverse transform is done by converting the PCS Y components to device Gray via the inverse of the grayTRC.
