  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.
  83  *
