public class CMYKConversion
extends java.lang.Object
Convert from CMYK color space to RGB color space.
static void | convertCMYK32InterleavedToRGB24Planar(byte[] cmyk, int cmykOffset, byte[] red, int redOffset, byte[] green, int greenOffset, byte[] blue, int blueOffset, int numPixels) - Converts a number of CMYK pixels stored in interleaved order (all samples of one pixel
together: CMYKCMYKCMYK...) to RGB pixels which are stored as planes (all red samples
together, etc.).

int cmykOffset,
byte[] red,
int redOffset,
byte[] green,
int greenOffset,
byte[] blue,
int blueOffset,

Converts a number of CMYK pixels stored in interleaved order (all samples of one pixel
together: CMYKCMYKCMYK...) to RGB pixels which are stored as planes (all red samples
together, etc.).
cmyk
- a byte array with numPixels times four samples stored in order C-M-Y-KcmykOffset
- the index of the first byte that is to be accessedred
- the byte array to which the red samples will be written by this methodredOffset
- the offset into the red array of the first sample to be writtengreen
- the byte array to which the green samples will be written by this methodgreenOffset
- the offset into the green array of the first sample to be writtenblue
- the byte array to which the blue samples will be written by this methodblueOffset
- the offset into the blue array of the first sample to be written

convertCMYK32ToRGB24
public static void convertCMYK32ToRGB24(int cyan,
int magenta,
int yellow,
int black,
int[] rgb)
Converts a 32 bit CMYK pixel to a 24 bit RGB pixel.
Red, green and blue sample will be written at the indexes that
RGBIndex
defines for them.
cyan
- the cyan sample, must lie in the interval 0 to 255magenta
- the magenta sample, must lie in the interval 0 to 255yellow
- the yellow sample, must lie in the interval 0 to 255black
- the black sample, must lie in the interval 0 to 255rgb
- byte array for the destination R-G-B pixel, must have length 3 or larger, will be accessed using RGBIndex, each sample will lie in the interval 0 to 255
