/**

 * 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 {@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.

 *

 * @see ICC_ColorSpace
