Method Summary

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.).
static void	convertCMYK32PlanarToRGB24Planar(byte[] cyan, int cyanOffset, byte[] magenta, int magentaOffset, byte[] yellow, int yellowOffset, byte[] black, int blackOffset, byte[] red, int redOffset, byte[] green, int greenOffset, byte[] blue, int blueOffset, int numPixels)

Method Detail

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.

Parameters:

cyan - the cyan sample, must lie in the interval 0 to 255

magenta - the magenta sample, must lie in the interval 0 to 255

yellow - the yellow sample, must lie in the interval 0 to 255

black - the black sample, must lie in the interval 0 to 255

rgb - 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

                                                         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.).

Parameters:

cmyk - a byte array with numPixels times four samples stored in order C-M-Y-K

cmykOffset - the index of the first byte that is to be accessed

red - the byte array to which the red samples will be written by this method

redOffset - the offset into the red array of the first sample to be written

green - the byte array to which the green samples will be written by this method

greenOffset - the offset into the green array of the first sample to be written

blue - the byte array to which the blue samples will be written by this method

blueOffset - the offset into the blue array of the first sample to be written
