/**

 * A representation of color profile data for device independent and

 * device dependent color spaces based on the International Color

 * Consortium Specification ICC.1:2001-12, File Format for Color Profiles,

 * (see <A href="http://www.color.org"> http://www.color.org</A>).

 * <p>

 * An ICC_ColorSpace object can be constructed from an appropriate

 * ICC_Profile.

 * Typically, an ICC_ColorSpace would be associated with an ICC

 * Profile which is either an input, display, or output profile (see

 * the ICC specification).  There are also device link, abstract,

 * color space conversion, and named color profiles.  These are less

 * useful for tagging a color or image, but are useful for other

 * purposes (in particular device link profiles can provide improved

 * performance for converting from one device's color space to

 * another's).

 * <p>

 * ICC Profiles represent transformations from the color space of

 * the profile (e.g. a monitor) to a Profile Connection Space (PCS).

 * Profiles of interest for tagging images or colors have a PCS

 * which is one of the two specific device independent

 * spaces (one CIEXYZ space and one CIELab space) defined in the

 * ICC Profile Format Specification.  Most profiles of interest

 * either have invertible transformations or explicitly specify

 * transformations going both directions.

 * <p>

 * @see ICC_ColorSpace
