NAME
     mlibVideoColorJFIFYC2RGB420Nearest - JFIF  YCbCr  to  RGB
     color conversion

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibVideoColorJFIFYC2RGB420Nearest(mlibu8 *rgb0,
          mlibu8 *rgb1, const mlibu8 *y0,
          const mlibu8 *y1, const mlibu8 *cb,
          const mlibu8 *cr, mlibs32 n);


DESCRIPTION
     The  mlibVideoColorJFIFYC2RGB420Nearest()  function  per-
     forms color space conversion from YCbCr to RGB together with
     sampling rate conversion when used in the JPEG  File  Inter-
     change 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.


     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.


     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-component row must be 3*n.
