NAME
mlib_VideoColorJFIFYCCK2CMYK444 - JFIF YCbCr to CMYK color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorJFIFYCCK2CMYK444(mlib_u8 *cmyk, const mlib_u8 *y, const mlib_u8 *cb, const mlib_u8 *cr, const mlib_u8 *k, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorJFIFYCCK2CMYK444() function performs color space conversion from YCbCrK to CMYK when used in the JPEG File Interchange Format (JFIF). The following equation is used: R = Y + 1.40200 * (Cr - 128) G = Y - 0.34414 * (Cb - 128) - 0.71414 * (Cr - 128) B = Y + 1.77200 * (Cb - 128) C = (255 - R) M = (255 - G) Y = (255 - B) K = K
PARAMETERS
The function takes the following arguments: cmyk Pointer to destination CMYK multi-component row. cmyk must be 8-byte aligned. y Pointer to source Y component row. y must be 8-byte aligned. cb Pointer to source Cb component row. cb must be 8-byte aligned. cr Pointer to source Cr component row. cr must be 8-byte aligned. k Pointer to source K component row. k must be 8-byte aligned. n Length of Y, Cb, Cr, and K component rows. The length of the CMYK multi-component row must be 4*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
