NAME
       mlib_VideoColorJFIFYCC2RGB420 - JFIF YCbCr to RGB color conversion

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoColorJFIFYCC2RGB420(mlib_u8 *rgb0,
	   mlib_u8 *rgb1, const mlib_u8 *y0,
	   const mlib_u8 *y1, const mlib_u8 *cb0,
	   const mlib_u8 *cr0, const mlib_u8 *cb1,
	   const mlib_u8 *cr1, const mlib_u8 *cb2,
	   const mlib_u8 *cr2, mlib_s32 n);

DESCRIPTION
       The  mlib_VideoColorJFIFYCC2RGB420() function performs color space con‐
       version from YCbCr to RGB together with sampling rate  conversion  when
       used in the JPEG File Interchange Format (JFIF).

PARAMETERS
       The function takes the following arguments:

       rgb0    Pointer to upper destination RGB multi-component row. rgb0 must
	       be 8-byte aligned.

       rgb1    Pointer to lower destination RGB multi-component row. rgb1 must
	       be 8-byte aligned.

       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.

       cb0     Pointer	to  source  upper Cb component row. cb0 must be 8-byte
	       aligned.

       cr0     Pointer to source upper Cr component row. cr0  must  be	8-byte
	       aligned.

       cb1     Pointer	to  source middle Cb component row. cb1 must be 8-byte
	       aligned.

       cr1     Pointer to source middle Cr component row. cr1 must  be	8-byte
	       aligned.

       cb2     Pointer	to  source  lower Cb component row. cb2 must be 8-byte
	       aligned.

       cr2     Pointer to source lower Cr component row. cr2  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 RGB multi-com‐
	       ponent row must be 3*n.

RETURN VALUES
       The  function  returns MLIB_SUCCESS if successful. Otherwise it returns
       MLIB_FAILURE.
