NAME
mlib_VideoColorBGR2JFIFYCC444 - BGR to JFIF YCbCr color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorBGR2JFIFYCC444(mlib_u8 *y, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *bgr, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorBGR2JFIFYCC444() function performs color space conversion from BGR to YCbCr when used in the JPEG File Interchange For- mat (JFIF). The following equation is used: Y = 0.29900 * R + 0.58700 * G + 0.11400 * B Cb = -0.16874 * R - 0.33126 * G + 0.50000 * B + 128 Cr = 0.50000 * R - 0.41869 * G - 0.08131 * B + 128
PARAMETERS
The function takes the following arguments: y Pointer to destination Y component row. y must be 8-byte aligned. cb Pointer to destination Cb component row. cb must be 8-byte aligned. cr Pointer to destination Cr component row. cr must be 8-byte aligned. bgr Pointer to source BGR multi-component row. bgr must be 8-byte aligned. n Length of Y component row. The length of Cb and Cr component rows must be n. The length of the BGR multi-component row must be 3*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
