java.awt.color.ICC_ProfileRGB
public class ICC_ProfileRGB
ICC_ProfileRGB - a special case of ICC_Profiles. The ICC_Profile.getInstance() method will return an instance of the ICC_ProfileRGB subclass when all the following conditions are met: The device color space of the profile is TYPE_RGB. The profile contains red, green and blue ColorantTags. The profile contains red, green and blue TRCTags. The profile contains a mediaWhitePointTag included. As per the ICC specification, the color space conversion can then be done through the following method: linearR = redTRC[deviceR] linearG = greenTRC[deviceG] linearB = blueTRC[deviceB] TRC curves are either a single gamma value, or a 1-dimensional lookup table. Followed by the matrix transform: PCS = M*linear Where PCS is the vector of profile color space (must be XYZ) coordinates, linear is the vector of linear RGB coordinates, and the matrix M is constructed from the ColorantTags, where the columns are red, green and blue respectively, and the rows are X, Y and Z. Note that if the profile contains a CLUT for the color space conversion, it should be used instead, and the TRC information ignored.
