Examples of this kind of profile are three-component matrix-based input profiles and RGB display profiles. The getInstance methods in the ICC_Profile class will return an ICC_ProfileRGB object when the above conditions are met. The advantage of this class is that it provides color transform matrices and lookup tables that Java or native methods may be able to use directly to optimize color conversion in some cases. <p> To transform from a device profile color space to the CIEXYZ Profile Connection Space, each device color component is first linearized by a lookup through the corresponding tone reproduction curve (TRC). Then the resulting linear RGB components are converted via a 3x3 matrix (constructed from the RGB colorants) to the CIEXYZ PCS.<pre> linearR = redTRC[deviceR] linearG = greenTRC[deviceG] linearB = blueTRC[deviceB] _ _ _ _ _ _ [ PCSX ] [ redColorantX greenColorantX blueColorantX ] [ linearR ] [ ] [ ] [ ] [ PCSY ] = [ redColorantY greenColorantY blueColorantY ] [ linearG ] [ ] [ ] [ ] [_ PCSZ _] [_ redColorantZ greenColorantZ blueColorantZ _] [_ linearB _]</pre> The inverse transform is done by converting PCS XYZ components to linear RGB components via the inverse of the above 3x3 matrix, and then converting linear RGB to device RGB via inverses of the TRCs. <p><P><DL><DT><B>See Also: </B><DD><A HREF="../../../serialized-form.html#java.awt.color.ICC_ProfileRGB">Serialized
