67 * A representation of color profile data for device independent and
68 * device dependent color spaces based on the International Color
69 * Consortium Specification ICC.1:2001-12, File Format for Color Profiles,
70 * (see <A href="http://www.color.org"> http://www.color.org</A>).
71 * <p>
72 * An ICC_ColorSpace object can be constructed from an appropriate
73 * ICC_Profile.
74 * Typically, an ICC_ColorSpace would be associated with an ICC
75 * Profile which is either an input, display, or output profile (see
76 * the ICC specification). There are also device link, abstract,
77 * color space conversion, and named color profiles. These are less
78 * useful for tagging a color or image, but are useful for other
79 * purposes (in particular device link profiles can provide improved
80 * performance for converting from one device's color space to
81 * another's).
82 * <p>
83 * ICC Profiles represent transformations from the color space of
84 * the profile (e.g. a monitor) to a Profile Connection Space (PCS).
85 * Profiles of interest for tagging images or colors have a PCS
86 * which is one of the two specific device independent
87 * spaces (one CIEXYZ space and one CIELab space) defined in the
88 * ICC Profile Format Specification. Most profiles of interest
89 * either have invertible transformations or explicitly specify
90 * transformations going both directions.

1921 * resolve the bogus deserialized profile object with one obtained
1922 * with getInstance as well.
1923 *
1924 * There are two primary factory methods for construction of ICC
1925 * profiles: getInstance(int cspace) and getInstance(byte[] data).
1926 * This implementation of ICC_Profile uses the former to return a
1927 * cached singleton profile object, other implementations will
1928 * likely use this technique too. To preserve the singleton
1929 * pattern across serialization we serialize cached singleton
1930 * profiles in such a way that deserializing VM could call
1931 * getInstance(int cspace) method that will resolve deserialized
1932 * object into the corresponding singleton as well.
1933 *
1934 * Since the singletons are private to ICC_Profile the readResolve
1935 * method have to be `protected' instead of `private' so that
1936 * singletons that are instances of subclasses of ICC_Profile
