mediaLib Library Functions      mlib_ImageColorRGB2CIEMono(3MLIB)



NAME
     mlib_ImageColorRGB2CIEMono - RGB to monochrome conversion

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

     mlib_status mlib_ImageColorRGB2CIEMono(mlib_image *dst,
          const mlib_image *src);


DESCRIPTION
     The mlib_ImageColorRGB2CIEMono() function performs a conver-
     sion  from  a  red/green/blue  to a monochromatic image. The
     source image must be a three-channel image. The  destination
     image must be a single-channel image.


     It uses the following equation:

       dst[x][y][0] = 0.2125*src[x][y][0] +
                      0.7154*src[x][y][1] +
                      0.0721*src[x][y][2]


PARAMETERS
     The function takes the following arguments:

     dst    Pointer to destination image.


     src    Pointer to source image.


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