/**
 * 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.
 * @see ICC_ColorSpace
