public class ICC_ColorSpace
ICC_ColorSpace - an implementation of ColorSpace While an ICC_Profile class abstracts the data in an ICC profile file an ICC_ColorSpace performs the color space conversions defined by an ICC_Profile instance. Typically, an ICC_Profile will either be created using getInstance, either from the built-in colorspaces, or from an ICC profile file. Then a ICC_Colorspace will be used to perform transforms from the device colorspace to and from the profile color space. The PCS used by ColorSpace is CIE XYZ relative a D50 white point. (Profiles using a CIE Lab PCS will have their input and output converted to D50 CIE XYZ accordingly. Note that a valid profile may not contain transforms in both directions, in which case the output may be undefined. All built-in colorspaces have bidirectional transforms, but developers using an ICC profile file may want to check the profile class using the ICC_Profile.getProfileClass() method. Input class profiles are guaranteed to have transforms to the PCS, output class profiles are guaranteed to have transforms from the PCS to device space.
