Most of the images are saved in RGB color space. Also Indexed and Grayscale color spaces may be used. CMYK color space is never used.
For some images the color space may be different on different platforms.
public static final int SIMPLE_CMYK
Images in RGB color space are converted to CMYK using formula: Black = minimum(1-Red,1-Green,1-Blue). Cyan = (1-Red-Black)/(1-Black). Magenta = (1-Green-Black)/(1-Black). Yellow = (1-Blue-Black)/(1-Black). RGB values are normalized - they are between 0 and 1.0.
