SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorARGB2JFIFYCC420(mlib_u8 *y0,
mlib_u8 *y1, mlib_u8 *cb, mlib_u8 *cr, const mlib_u8 *argb0,
const mlib_u8 *argb1, mlib_s32 n);
DESCRIPTION
The mlib_VideoColorARGB2JFIFYCC420() function performs color space con‐
version from ARGB to YCbCr together with sampling rate conversion when
used in the JPEG File Interchange Format (JFIF).
PARAMETERS
The function takes the following arguments:
y0 Pointer to upper destination Y component row. y0 must be
8-byte aligned.
y1 Pointer to lower destination Y component row. y1 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.
argb0 Pointer to upper source ARGB multi-component row. argb0 must
be 8-byte aligned.
argb1 Pointer to lower source ARGB multi-component row. argb1 must
be 8-byte aligned.
n Length of Y component row. n must be even. The length of Cb
and Cr component rows must be n/2. The length of the ARGB
multi-component row must be 4*n.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
