mediaLib Library Functions         mlibImageColorConvert2(3MLIB)



NAME
     mlibImageColorConvert2  -  color  conversion  using  a  3x3
     floating-point matrix and a three-element offset

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

     mlibstatus mlibImageColorConvert2(mlibimage *dst, const mlibimage *src,
          const mlibd64 *cmat, const mlibd64 *offset);


DESCRIPTION
     The   mlibImageColorConvert2()   function   takes   a   3x3
     floating-point  conversion matrix and a three-element offset
     and converts the source color image to the destination color
     image.


     The source and  destination  images  must  be  three-channel
     images.


     It uses the following equation:

       dst[x][y][0]  cmat[0] cmat[1] cmat[2]  src[x][y][0]  offset[0]
       dst[x][y][1] =cmat[3] cmat[4] cmat[5] *src[x][y][1] ]offset[1]
       dst[x][y][2]  cmat[6] cmat[7] cmat[8]  src[x][y][2]  offset[2]


PARAMETERS
     The function takes the following arguments:

     dst       Pointer to destination image.


     src       Pointer to source image.


     cmat      Conversion matrix in row major order.


     offset    Offset array.


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