NAME
mlib_VideoColorBGR2JFIFYCC444_S16 - BGR to JFIF YCbCr color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoColorBGR2JFIFYCC444_S16(mlib_s16 *y, mlib_s16 *cb, mlib_s16 *cr, const mlib_s16 *bgr, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorBGR2JFIFYCC444_S16() function performs color space conversion from BGR to YCbCr when used in the JPEG File Interchange Format (JFIF). Both the input BGR components and the output YCbCr components are supposed to be in the range of [0, 4095]. 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 + 2048 Cr = 0.50000 * R - 0.41869 * G - 0.08131 * B + 2048
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.
