| * Specification ICC.1:2001-12, File Format for Color Profiles, (see |
| * <a href="http://www.color.org"> http://www.color.org</a>). |
| * <p> |
| * An {@code ICC_ColorSpace} object can be constructed from an appropriate |
| * {@code ICC_Profile}. Typically, an {@code 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. |

| * |
| * There are two primary factory methods for construction of ICC profiles: |
| * getInstance(int cspace) and getInstance(byte[] data). This implementation |
| * of ICC_Profile uses the former to return a cached singleton profile |
| * object, other implementations will likely use this technique too. To |
| * preserve the singleton pattern across serialization we serialize cached |
| * singleton profiles in such a way that deserializing VM could call |
| * getInstance(int cspace) method that will resolve deserialized object into |
| * the corresponding singleton as well. |
| * |
| * Since the singletons are private to ICC_Profile the readResolve method |
| * have to be `protected' instead of `private' so that singletons that are |
| * instances of subclasses of ICC_Profile could be correctly deserialized. |
