mediaLib Library Functions   mlibVideoColorJFIFYC2RGB422(3MLIB)



NAME
     mlibVideoColorJFIFYC2RGB422 -  JFIF  YCbCr  to  RGB  color
     conversion

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

     mlibstatus mlibVideoColorJFIFYC2RGB422(mlibu8 *rgb,
          const mlibu8 *y, const mlibu8 *cb,
          const mlibu8 *cr, mlibs32 n);


DESCRIPTION
     The mlibVideoColorJFIFYC2RGB422() function performs  color
     space  conversion  from  YCbCr to RGB together with sampling
     rate conversion when used in the JPEG File Interchange  For-
     mat (JFIF).

PARAMETERS
     The function takes the following arguments:

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


     y      Pointer to destination Y component row. y 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.


RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
