/**
* 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
