61 /**
62 * A representation of color profile data for device independent and device
63 * dependent color spaces based on the International Color Consortium
64 * Specification ICC.1:2001-12, File Format for Color Profiles, (see
65 * <a href="http://www.color.org"> http://www.color.org</a>).
66 * <p>
67 * An {@code ICC_ColorSpace} object can be constructed from an appropriate
68 * {@code ICC_Profile}. Typically, an {@code ICC_ColorSpace} would be associated
69 * with an ICC Profile which is either an input, display, or output profile (see
70 * the ICC specification). There are also device link, abstract, color space
71 * conversion, and named color profiles. These are less useful for tagging a
72 * color or image, but are useful for other purposes (in particular device link
73 * profiles can provide improved performance for converting from one device's
74 * color space to another's).
75 * <p>
76 * ICC Profiles represent transformations from the color space of the profile
77 * (e.g. a monitor) to a Profile Connection Space (PCS). Profiles of interest
78 * for tagging images or colors have a PCS which is one of the two specific
79 * device independent spaces (one CIEXYZ space and one CIELab space) defined in
80 * the ICC Profile Format Specification. Most profiles of interest either have
81 * invertible transformations or explicitly specify transformations going both
82 * directions.

1893 * object with one obtained with getInstance as well.
1894 *
1895 * There are two primary factory methods for construction of ICC profiles:
1896 * getInstance(int cspace) and getInstance(byte[] data). This implementation
1897 * of ICC_Profile uses the former to return a cached singleton profile
1898 * object, other implementations will likely use this technique too. To
1899 * preserve the singleton pattern across serialization we serialize cached
1900 * singleton profiles in such a way that deserializing VM could call
1901 * getInstance(int cspace) method that will resolve deserialized object into
1902 * the corresponding singleton as well.
1903 *

1905 * have to be `protected' instead of `private' so that singletons that are
1906 * instances of subclasses of ICC_Profile could be correctly deserialized.
